+ CircleCI: Test for Python 3 syntax errors and undefined names (#1522)

+
+ __E901,E999,F821,F822,F823__ are the "_showstopper_"
+ [flake8](http://flake8.pycqa.org) issues that can halt the runtime
+ with a SyntaxError, NameError, etc. Most other flake8 issues are
+ merely "style violations" -- useful for readability but they do not
+ effect runtime safety.
+ * F821: undefined name `name`
+ * F822: undefined name `name` in `__all__`
+ * F823: local variable name referenced before assignment
+ * E901: SyntaxError or IndentationError
+ * E999: SyntaxError -- failed to compile a file into an Abstract
+ Syntax Tree

+ Fix build on older Visual Studio versions (#1499)
+
+ * src/hb-cff-interp-dict-common.hh: Use ull for unsigned int64_t
+
+ The llu suffix does not work for older Visual Studio versions
+ (pre-2013), but ull works for all the compilers that we attempt to
+ support.
+
+ * test/api: Fix build on pre-C99 compilers
+
+ Ensure variables are declared at the top of the block.
+
+ * src/hb-dsalgs.hh: Add specialization for hb_is_signed<> for __int8
+
+ Pre-Visual Studio 2010 does not consider __int8 (which is typedef'ed
+ to
+ int8_t) to be equivilant to signed char, so the compiler cannot
+ find the
+ corresponding hb_is_signed<> specialization that is needed.
+
+ The interesting thing is unsigned __int8 is considered to be
+ equivilant
+ to unsigned char, so as the other types (short, int, long) that
+ we look
+ for here, so only the specialization for __int8 is added here.
+
+ This will fix builds on Visual Studio 2008 at least.

+
+ Make shaper's override_features() override user features as well
+
+ The override_features is used to override features that are normally
+ discretionary features, but in a specific shaper are for various
+ reasons desired to be bolted on or off, because they've been used
+ for inherent shaping. As such, it makes sense that they also
+ override user features. Ie. if user turned 'liga' on, we don't
+ want Khmer shaping to become broken... Or turn 'clig' off...

+
+ Optimize harfbuzz big integer conversions
+
+ Profiling showed that type conversions were adding considerable
+ cycles in time
+ spent doing text shaping.
+
+ The idea is to optimize it using native processor instructions to
+ help Blink
+ layout performance.
+
+ Doing further investigation revelead that compilers may not use the
+ proper instruction on ARM 32bits builds (i.e. REV16).
+
+ One way to insure that the generated ASM was ideal for both gcc/clang
+ was using __builtin_bswap16.
+
+ Added bonus is that we no longer need to test for CPU architecture.

+
+ [aat.morx] Remove set_object() business
+
+ With OS X 10.13 Apple Chancery fails to ligate if we limit each morx
+ sub-chain to its declared length. Perhaps their newer compiler does
+ object-sharing across sub-chains. Anyway, since that's a valid, if
+ unspecified, way to compile tables, remove enforcement.
+
+ Probably do the same with kern/kerx.

+ Revert b4c61130324455bfd42095b01fa14ac901e441f1
+
+ Was causing more trouble than it solved. We use unsigned for
+ indexing,
+ and it's not helpful to allow that wrapping to negative integers on
+ 32bit machines. The only way we could work around it would have been
+ by accepting int64_t arg, but that's overkill.
+
+ Ignore the MSVC 2008 build issue. We don't support that compiler.

+ Detect over/under-flow in UnsizedArray::operator[]
+
+ Was causing bad substitutions in mort table because of
+ WordOffsetToIndex()
+ producing negative numbers that were cast to unsigned int and
+ returned as
+ large numbers (which was desirable, so they would be rejected),
+ but then
+ they were cast to int when passed to this operator and acting as small
+ negative integers, which was bad...
+
+ Detect overflow. Ouch, however, now I see this still fails on 32-bit.
+ Guess I'm going to revert an earlier change.

+
+ The mark positioning (kern table CrossStream kerning) only works

+ [kern] In Format1, adjust how kerning is done
+
+ In a series of kerns in one action, kern all but last glyph forward,
+ and the last one backward. Seems to better match what CoreText
+ is doing.
+
+ Test cases, with GeezaPro Arabic:
+
+ $ ./hb-shape GeezaPro_10_10.ttc -u U+0631,U+0628
+ [u0628.beh=1+1415|u0631.reh=0@-202,0+700]
+
+ $ ./hb-shape GeezaPro_10_10.ttc -u U+0628,U+064F
+ [u064f.damma=0@0,-250+-250|u0628.beh=0@250,0+1665]
+
+ In a later change, I'll make kern machine avoid producing negative
+ kerns.

+ Make constructor / destructor call init_shallow/fini_shallow,

+ on stack now and no init/fini call is needed. As such,
+ hb_auto_t<> is not needed anymore. I'll remove that separately.

+
+ Remove ASSERT_POD
+
+ Newer compilers / language allows structs with constructor in union.
+ So, this was not actually testing anything. Indeed, the recent
+ change in DISALLOW_COPY *is* making some of our types non-POD.
+ That broke some bots.
+
+ Just remove this since it wasn't doing much, and I'd rather have
+ DISALLOW_COPY.

+ Make Array types uncopyable-unassignable
+
+ Finally! Catches hard-to-find errors like this:
+
+ - const SortedArrayOf<SVGDocumentIndexEntry> docs =
+ this+svgDocEntries;
+ + const SortedArrayOf<SVGDocumentIndexEntry> &docs =
+ this+svgDocEntries;
+
+ We implement this for our array types. This, in turn, trickles down
+ into all types that embed the arrays. So, as long as we define all
+ open-ended structs in terms of Array types (all can be done using
+ UnsizedArrayOf), this achieves the goal of making uncopyable all
+ structs that are variable-sized. Yay!

+ We had this exposed as unsigned int since 2.0.0 release in two APIs,

+ But since no one uses those (right?!), let's just fix this now.

+
+ Remove some use of Crap in hb-set.
+
+ When hb_set_t::page_for_insert needs to insert at the end of the
+ page_map
+ it ends up evaluating '&page_map[i + 1]' which has hb_vector return an
+ lvalue of a Crap so that nothing can be moved to its address. This
+ turns
+ into issues with ThreadSanitizer on Crap when two threads modify
+ different
+ hb_set_t instances. This can be avoided by using '&page_map[i] + 1'
+ instead.

+ [morx] Leave ligature on stack after ligating

+ ./hb-shape Apple\ Color\ Emoji-old.ttf --font-funcs=ot -u
+ U+1F468,200d,U+1F469,200d,U+1F467,200d,1f466
+
+ Should form full family if matching works correctly. It first makes
+ family of three, then makes family of four out of that and the last
+ two characters.

+ Actually the check is right,
+
+ On -myanmar.hh, on that particular switch, OT_C is indic_category_t

+
+ And on -arabic.cc, step can goes one number higher than step_t enum

+
+ Add two APIs for getting stylistic set labels
+
+ * hb_ot_layout_feature_get_characters
+ * hb_ot_layout_feature_get_name_ids
+
+ However HarfBuzz currently doesn't expose an API for retrieving
+ the actual
+ information associated with NameId from the `name` table and that
+ should be
+ done separately.

+ Map Quechua languages to closest ones with tags
+
+ OpenType only officially maps four ISO 639 codes to Quechua languages,
+ but prior versions of HarfBuzz also mapped qu to 'QUZ '. Because qu
+ is a
+ macrolanguage, the mapping now applies to all individual Quechua
+ languages. OpenType calls 'QUZ ' "Quechua", but it really corresponds
+ to
+ Cusco Quechua, so the individual Quechua languages should not all
+ necessarily be mapped to it.

+
+ Test deprecated tag fallback in a font
+
+ The font supports the deprecated tag 'DHV ' instead of 'DIV '. dv is
+ mapped to 'DIV ' and 'DHV ', in that order. The test specifies
+ `--language=dv`, demonstrating that if a font does not support
+ the first
+ OpenType tag mapped to a BCP 47 tag, it will fall back to the

+ Match extlang subtags
+
+ If the second subtag of a BCP 47 tag is three letters long, it denotes
+ an extended language. The tag converter ignores the language
+ subtag and
+ uses the extended language instead.
+
+ There are some grandfathered exceptions, which are handled earlier.

+
+ Autogenerate the BCP 47 to OpenType mappings
+
+ The new script, gen-tag-table.py, generates `ot_languages`
+ automatically
+ from the [OpenType language system tag registry][ot] and the [IANA
+ Language Subtag Registry][bcp47] with some manual modifications. If an
+ OpenType tag maps to a BCP 47 macrolanguage, all the macrolanguage's
+ individual languages are mapped to the same OpenType tag, except for
+ individual languages with their own OpenType mappings. Deprecated
+ BCP 47 tags are canonicalized.
+
+ [ot]:
+ https://docs.microsoft.com/en-us/typography/opentype/spec/languagetags
+ [bcp47]:
+ https://www.iana.org/assignments/language-subtag-registry/language-subtag-registry
+
+ Some OpenType tags correspond to multiple ISO 639 codes. The mapping
+ from ISO 639 codes lists OpenType tags in priority order, such
+ that more
+ specific or more likely tags appear first.
+
+ Some OpenType tags have no corresponding ISO 639 code in the
+ registry so
+ their mappings use BCP 47 subtags besides the language. For example,
+ any
+ BCP 47 tag with a fonipa variant subtag is mapped to 'IPPH', and
+ 'IPPH'
+ is mapped back to und-fonipa.
+
+ Other OpenType tags have no corresponding ISO 639 code because it
+ is not
+ clear what they are for. HarfBuzz just ignores these tags.
+
+ One such ignored tag is 'ZHP ' (Chinese Phonetic). It probably means
+ zh-Latn. However, it is used in Microsoft JhengHei and Microsoft YaHei
+ with the script tag 'hani', implying that it is not a romanization
+ scheme after all. It would be simple enough to add this mapping to
+ gen-tag-table.py once a definitive mapping is determined.
+
+ The manual modifications are mainly either obvious mappings that the
+ OpenType registry omits or mappings for compatibility with previous
+ versions of HarfBuzz. Some of the old mappings were discarded, though,
+ for homophonous language names. For example, OpenType maps 'KUI ' to
+ kxu; previous versions of HarfBuzz also mapped it to kvd, because kvd
+ and kxu both happen to be called "Kui".
+
+ gen-tag-table.py also generates a function to convert multi-subtag
+ tags
+ like el-polyton and zh-HK to OpenType tags, replacing
+ `ot_languages_zh`
+ and the hard-coded list of special cases in
+ `hb_ot_tags_from_language`.
+ It also generates a function to convert OpenType tags to BCP 47,
+ replacing the hard-coded list of special cases in
+ `hb_ot_tag_to_language`.

+Author: David Corbett <corbett.dav@husky.neu.edu>
+Date: Fri Dec 8 11:21:14 2017 -0500
+
+ Refactor the selection of script and language tags
+
+ The old hb-ot-tag.cc functions, `hb_ot_tags_from_script` and
+ `hb_ot_tag_from_language`, are now wrappers around a new function:
+ `hb_ot_tags`. It converts a script and a language to arrays of script
+ tags and language tags. This will make it easier to add new script
+ tags
+ to scripts, like 'dev3'. It also allows for language fallback chains;
+ nothing produces more than one language yet though.
+
+ Where the old functions return the default tags 'DFLT' and 'dflt',
+ `hb_ot_tags` returns an empty array. The caller is responsible for
+ using the default tag in that case.
+
+ The new function also adds a new private use subtag syntax for script
+ overrides: "x-hbscabcd" requests a script tag of 'abcd'.
+
+ The old hb-ot-layout.cc functions,`hb_ot_layout_table_choose_script`
+ and
+ `hb_ot_layout_script_find_language` are now wrappers around the new
+ functions `hb_ot_layout_table_select_script` and
+ `hb_ot_layout_script_select_language`. They are essentially the
+ same as
+ the old ones plus a tag count parameter.
+
+ Closes #495.

+ [kerx] No-op
+
+ Tested that Format0 works with Kannada MN font:
+
+ $ make -j5 lib -s && HB_OPTIONS=aat ./hb-shape Kannada\ MN.ttc
+ -u 0C95,0CC2
+ [kn_ka=0+1000|kn_matra_uu=0@-30,0+1345]

+ 0C95,0CC2 --features=-kern
+ [kn_ka=0+1030|kn_matra_uu=0+1375]
+
+ Note that GPOS does the same with 'dist' feature, and applies the
+ whole difference to the
+ same glyph:
+
+ $ make -j5 lib -s && ./hb-shape Kannada\ MN.ttc -u 0C95,0CC2
+ [kn_ka=0+970|kn_matra_uu=0+1375]
+

+
+ [ot-font] Don't pre-load cmap table
+
+ Now that we have get_h_advances() and get_nominal_glyphs()
+ implemented, the
+ overhead of doing a proper atomic load would be once per run, NOT
+ once per
+ glyph. So, no need to pre-load the tables to avoid that overhead.
+
+ As such, hb_ot_font_set_funcs() has become really cheap.
+ Can *finally* make
+ it be default font functions on all newly created fonts!

+
+ [ot/ft] Implement get_nominal_glyphs() callback
+
+ Some more measurable speedup. The recent commits' speedups are
+ as follows:
+
+ Testing with Roboto, ****when disabling kern and liga****:
+
+ Before:
+
+ FT --features=-kern,-liga
+ user↦ 0m0.521s
+
+ OT --features=-liga,-kern
+ user↦ 0m0.568s
+
+ After:
+
+ FT --features=-liga,-kern
+ user↦ 0m0.428s
+
+ OT --features=-liga,-kern
+ user↦ 0m0.470s
+
+ So, 17% speedup.
+
+ Note that FT callbacks are faster than OT these days since we added
+ an advance
+ cache to FT. I don't think the difference is enough to justify
+ adding a cache
+ to OT.
+
+ When not disabling kern, the thing is three times slower, so the
+ speedups
+ are three times less impressive... Still, 5% not bad for a codebase
+ that I
+ otherwise thought is optimized out.
+
+ Note that, because of this and other optimiztions in our main shaper,
+ disabling kern and liga, the OT shaper is now *faster* than the
+ fallback
+ shaper. So, that's my recommendation to clients that need the
+ absolute
+ fastest...

+
+ Even without FT or OT font funcs implementing get_nominal_glyphs(),

+ builds: Fix and clean up MSVC DLL builds
+
+ Instead of passing a CFLAG/CXXFLAG to define HB_EXTERN, define it
+ directly in src/hb.hh as __declspec(dllexport) extern when we are
+ building HarfBuzz as DLLs on Visual Studio. Define HB_INTERNAL
+ as nothing without defining HB_NO_VISIBILITY when building HarfBuzz as
+ DLLs to avoid linker errors on Visual Studio builds.
+
+ Also "install" harfbuzz-subset.dll into $(PREFIX)\bin as the
+ hb-subset utility will depend on that DLL at runtime, when HarfBuzz is
+ built as DLLs. Since it consists of private APIs that are subject to
+ change, we do not install its headers nor .lib file.

+ "The values in the right class table are stored pre-multiplied by the

+ class table are stored pre-multiplied by the number of bytes in one
+ row. This eliminates needing to multiply the row and column values
+ together to determine the location of the kerning value. The array can
+ be indexed by doing the right- and left-hand class mappings,
+ adding the
+ class values to the address of the array, and fetching the kerning
+ value to which the new address points."

+ [indic] Remove Consonant_Medial from grammar and code
+
+ The only Indic CM is U+0A75 GURMUKHI SIGN YAKASH, which Uniscribe
+ doesn't treat
+ specially, and font designers design for that. So, do the same.

+ [khmer] Rewrite grammar completely
+
+ Based on experimenting with Uniscribe to extract grammar and
+ categories.
+
+ Failures down from 44 to 35:
+
+ KHMER: 299089 out of 299124 tests passed. 35 failed (0.0117008%)
+
+ We still don't enforce the one-matra rule pre-decomposition,
+ but enforce
+ an order and one-matra-per-position post-decomposition.

+
+ Disallow null-enabled offsets to unsized structures...
+
+ ...like UnsizedArrayOf<>.
+
+ This fixes a class of crasher bugs, mostly with color and AAT tables.
+ We
+ cannot use nullable offsets to varsized data that does not declare
+ min_size,
+ because it's nost safe to use our fixed-size null pool for types
+ that have
+ their size external. So, use non_null'able offsets for these.
+
+ A further enhancement would be to make use of min_size in Null<>
+ itself.
+ Will try that after.

+ [dfont] Solve the mystery +2 offset thing!
+
+ Previously, ResourceForkHeader was defined as 30 bytes, having the
+ typeCountM1 as last member.
+ There was a mysterious offset-by-2 in the code, derived from FontTools
+ and JDK code this was
+ ported from.
+
+ In testing, I observed that typeListZ offset is actually 28.
+ Suggesting that the typeCountM1
+ does NOT actually belong to ResourceForkHeader, but belongs to the
+ array itself. Adjusting for
+ that resolves the mystery +2 offset hack, so everything is clean
+ and good now.
+
+ This, concludes my dfont hacking. The code looks great now, and
+ I'm happy to leave it.
+ Fuzzers might disagree though, we will see!

+ [ot-font] Return char-not-found if mapped to gid 0
+
+ OpenType cmap table can use gid=0 to mean "not covered" to produce
+ more optimized cmap subtables. Return false from get_nominal_glyph()
+ for those. hb-ft already does this.

+ Don't add reference in get_unicode_funcs() functions
+
+ Users don't expect a new reference returned from a get() function.
+ Indeed, all users of that API I foud where NOT destroying the

+ Just change the implementations to NOT return a reference.
+
+ This applies to the following APIs:
+ hb_unicode_funcs_get_default()
+ hb_glib_get_unicode_funcs()
+ hb_icu_get_unicode_funcs()

+ [iter] Make operator bool explicit

+ We would need to write:

+ for (Iter<T> it (...); bool (t); t++)
+
+ instead of:

+ for (Iter<T> it (...); t; t++)
+
+ But I think it's an improvement in code readability in the long term.

+ [atomic] On IBM, use light-weight sync for everything
+
+ lwsync() is a full read/write-barrier. That's all we need, never
+ need sync(). I'm not sure why an isync() was used in fetch_and_add,
+ but since that's a read-modify-write, I just changed it to have
+ lwsync() on both sides.

+ [atomic] Fix get() impl
+
+ Originally, glib's atomic_get was implemented as "memory_barrier;
+ load".
+ I copied this into cairo, fontconfig, and harfbuzz. However, that's
+ wrong. Correct way is "load; memory_barrier". The details are long
+ and hard to fully grasp. Best to read:
+
+ https://www.kernel.org/doc/Documentation/memory-barriers.txt
+
+ Also see my report against GNOME:
+
+ https://gitlab.gnome.org/GNOME/glib/issues/1449
+
+ Note that this is irrelevant if C++11-like atomic ops are available.

+
+ This reverts commit b1e5650c67266dc158f22355fed206cd1c413f70.
+
+ After lots of head-scratching and finally finding the only truly
+ readable source to be the good old:
+
+ https://www.kernel.org/doc/Documentation/memory-barriers.txt
+
+ I've convinced myself that we need consume memory-ordering on get().
+ The location of memory-barrier in a load should be after, not before
+ the load. That needs fixing. I'll do that separately.

+commit 1a96cc825dc9c8e3b6eef1403fe0864a1cfc0245
+Author: Behdad Esfahbod <behdad@behdad.org>
+Date: Tue Jul 31 11:45:32 2018 -0700
+
+ [khmer] Rewrite most of shaper to better follow spec
+
+ Khmer spec has only one reordering phase, and only simple prebase
+ matra and Coeng-Ro reordering. Implement that. Specifically,
+ this was done to address recognizing different orders of the matra
+ and Coeng-Ro sequence. That said, some combinations are now
+ reordered differently from Uniscribe. Not clear if that's intended
+ or a bug in Uniscribe. The following two sequences render the same
+ in Uniscribe whereas we reorder them differently:
+
+ U+17A0,U+17D2,U+179A,U+17C2
+ U+17A0,U+17C2,U+17D2,U+179A
+
+ For that reason, our test suite numbers regressed slightly. Used
+ to be at 34 for fails, now at:
+
+ KHMER: 299080 out of 299124 tests passed. 44 failed (0.0147096%)
+
+ But generally a good change, and removed lots of code.
+
+ Fixes https://github.com/harfbuzz/harfbuzz/issues/1026

+
+ Add a new API, hb_ot_layout_get_feature_name_ids (#976)
+
+ This new API returns cvXX and ssXX related NameId, things like
+ featUiLabelNameId, featUiTooltipTextNameId, sampleTextNameId,
+ ... of cvXX
+ and UINameId of ssXX, in a unified way.
+
+ However HarfBuzz currently doesn't expose an API for retrieving
+ the actual
+ information associated with NameId from the `name` table and that
+ should be
+ done separately.

+
+ gen-def.py: pass headers as arguments so that msys2 can convert
+ posix paths
+
+ When one is not using the msys2 python, the header files that are
+ passed in as environment
+ variable cannot be found.
+
+ https://ci.appveyor.com/project/fonttools/ttfautohint-py/build/1.0.65/job/rkremny4jjid9nl2#L803
+
+ This is because msys2 shell and make use POSIX paths
+ (e.g. /c/Users/clupo/...)
+ whereas non-msys2 python.exe uses native Windows paths
+ (e.g. C:\Users\clupo\...).
+
+ Msys2 will automatically convert command line arguments (but not
+ environment variables) from
+ POSIX to Windows paths when calling a native win32 executable,
+ so we pass the header paths
+ as arguments instead of environment variables.
+
+ This way the gen-def.py script can support both mingw python running
+ in an MSYS2 shell, and
+ native win32 python.

+ [indic] Adjust left-matra repositioning and Halant,ZWJ sequence
+
+ From the new code (first paragraph is from the OT Devanagari spec.):
+
+ /* o Reorder matras:
+ *
+ * If a pre-base matra character had been reordered before
+ applying basic
+ * features, the glyph can be moved closer to the main consonant
+ based on
+ * whether half-forms had been formed. Actual position for
+ the matra is
+ * defined as “after last standalone halant glyph, after
+ initial matra
+ * position and before the main consonant”. If ZWJ or ZWNJ
+ follow this
+ * halant, position is moved after it.
+ *
+ * IMPLEMENTATION NOTES:
+ *
+ * It looks like the last sentence is wrong. Testing, with Windows
+ 7 Uniscribe
+ * and Devanagari shows that the behavior is best described as:
+ *
+ * "If ZWJ follows this halant, matra is NOT repositioned after
+ this halant.
+ * If ZWNJ follows this halant, position is moved after it."
+ *
+ * Test case, with Adobe Devanagari or Nirmala UI:
+ *
+ * U+091F,U+094D,U+200C,U+092F,U+093F
+ * (Matra moves to the middle, after ZWNJ.)
+ *
+ * U+091F,U+094D,U+200D,U+092F,U+093F
+ * (Matra does NOT move, stays to the left.)
+
+ Fixes https://github.com/harfbuzz/harfbuzz/issues/1070
+
+ Test case added with Adobe Devanagari.

+ Adjust MarkBasePos heuristic in presence of MultipleSubst
+
+ From the issue:
+ "In this font, the virama,ya first forms a ligature, then decomposes
+ back to
+ virama,ya. This causes those two to be marked parts of a MultipleSubst
+ sequence. When attaching the matra, we look for the first of the
+ MultipleSubst
+ sequence because that's where we attach to (because of eg #740). In
+ this case,
+ the first glyph in the MultipleSubst sequence is a mark, so we skip
+ it and
+ attach to the base char before it."
+
+ Font in question is Nirmala UI from Windows 10. Test sequence:

+ Support pipe and friends on hb_blob_create_from_file (#1061)
+
+ With this hb-view/hb-shape support pipes and possibly socket and
+ named pipe
+ also, anything fails just on mmap.
+
+ We can later do the same for Windows also.
+
+ This however reveals two issues, the fact most of our bots don't
+ have HAVE_MMAP and using
+ this instead the other fread/fopen reader can make failure on CI. I
+ should look at them separately
+ this change however is very low risk I believe.

+
+ We were passing the font path directly to freetype so rendering
+ was broken when we are getting the font from stdin.
+
+ This fixes it by using FT_New_Memory_Face instead.
+
+ This fixes:
+ * build/util/hb-view /dev/stdin text < font.ttf
+ * build/util/hb-view - text < font.ttf
+ * cat font.ttf | build/util/hb-view - text
+
+ but doesn't work on
+ * cat font.ttf | build/util/hb-view /dev/stdin text
+

+ callbacks set on them, so they should work out of the box
+ without any callbacks set. If callbacks are set, everything

+- API changes:
+ The following functions do NOT reference their return value before
+ returning:
+ * hb_unicode_funcs_get_default()
+ * hb_glib_get_unicode_funcs()
+ * hb_icu_get_unicode_funcs()
+ This is consistent with their naming ("get", instead of "reference")
+ as well as how they are used in the wild (ie. no one calls destroy()

+8. Bring a 32bit version of `usp10.dll` for yourself from `C:\Windows\SysWOW64\usp10.dll` of your

that it is not a DirectWrite proxy ([for more info](https://en.wikipedia.org/wiki/Uniscribe)).
Rule of thumb, your `usp10.dll` should have a size more than 500kb, otherwise
it is designed to work with DirectWrite which Wine can't work with its original one.
Document them in NEWS. All API and API semantic changes should be clearly
marked as API additions, API changes, or API deletions. Document
deprecations. Ensure all new API / deprecations are in listed correctly in
- docs/harfbuzz-sections.txt
+ docs/harfbuzz-sections.txt. If release added new API, add entry for new
+ API index at the end of docs/harfbuzz-docs.xml.
If there's a backward-incompatible API change (including deletions for API
used anywhere), that's a release blocker. Do NOT release.
6. Do "make distcheck", if it passes, you get a tarball.
Otherwise, fix things and commit them separately before making release,
+ Note: Check src/hb-version.h and make sure the new version number is
+ there. Sometimes, it does not get updated. If that's the case,
+ "touch configure.ac" and rebuild. Also check that there is no hb-version.h
+ in your build/src file. Typically it will fail the distcheck if there is.
+ That's what happened to 2.0.0 going out with 1.8.0 hb-version.h... So, that's
+ a clue.
7. "make release-files". Enter your GPG password. This creates a sha256 hash
and signs it.
-8. Now that you have release files built, commit NEWS and configure.ac changes,
+8. Now that you have release files, commit NEWS, configure.ac, and src/hb-version.h,
as well as any REPLACEME changes you made. The commit message is simply the
release number. Eg. "1.4.7"
-General fixes:
-=============
-
-- Implement 'rand' feature.
-
-
API issues:
===========
- Add hb-cairo glue
-- Add sanitize API (and a cached version, that saves result on blob user-data)
-
-- BCP 47 language handling / API (language_matches?)
-
-- Add hb_font_create_unscaled()?
+- Add sanitize API.
- Add query / enumeration API for aalt-like features?

<p>
- Let's say we start with the following character sequence and cluster
- values:
- </p>
+ The basic shaping operations affect clusters in a predictable
+ manner when using level 0 or level 1:
+ </p>
+<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
+<li class="listitem"><p>
+ When two or more clusters <span class="emphasis"><em>merge</em></span>, the
+ resulting merged cluster takes as its cluster value the
+ <span class="emphasis"><em>minimum</em></span> of the incoming cluster values.
+ </p></li>
+<li class="listitem"><p>
+ When a cluster <span class="emphasis"><em>decomposes</em></span>, all of the
+ resulting child clusters inherit as their cluster value the
+ cluster value of the parent cluster.
+ </p></li>
+<li class="listitem"><p>
+ When a character is <span class="emphasis"><em>reordered</em></span>, the
+ reordered character and all clusters that the character
+ moves past as part of the reordering are merged into one cluster.
+ </p></li>
+</ul></div>
+<p>
+ The functionality, guarantees, and benefits of level 0 and level
+ 1 behavior can be seen with some examples. First, let us examine
+ what happens with cluster values when shaping involves cluster
+ merging with ligatures and decomposition.
+ </p>
+<p>
+ Let's say we start with the following character sequence (top row) and
+ initial cluster values (bottom row):
+ </p>
<pre class="programlisting">
- A,B,C,D,E
- 0,1,2,3,4
-</pre>
+ A,B,C,D,E
+ 0,1,2,3,4
+ </pre>
<p>
- We then map the characters to glyphs. For simplicity, let's assume
- that each character maps to the corresponding, identical-looking
- glyph:
- </p>
+ During shaping, HarfBuzz maps these characters to glyphs from
+ the font. For simplicity, let us assume that each character maps
+ to the corresponding, identical-looking glyph:
+ </p>
<pre class="programlisting">
- A,B,C,D,E
- 0,1,2,3,4
-</pre>
+ A,B,C,D,E
+ 0,1,2,3,4
+ </pre>
<p>
- Now if, for example, <code class="literal">B</code> and <code class="literal">C</code>
- ligate, then the clusters to which they belong "merge".
- This merged cluster takes for its cluster number the minimum of all
- the cluster numbers of the clusters that went in. In this case, we
- get:
- </p>
+ Now if, for example, <code class="literal">B</code> and <code class="literal">C</code>
+ form a ligature, then the clusters to which they belong
+ "merge". This merged cluster takes for its cluster
+ value the minimum of all the cluster values of the clusters that
+ went in to the ligature. In this case, we get:
+ </p>
<pre class="programlisting">
- A,BC,D,E
- 0,1 ,3,4
-</pre>
+ A,BC,D,E
+ 0,1 ,3,4
+ </pre>
<p>
- Now let's assume that the <code class="literal">BC</code> glyph decomposes
- into three components, and <code class="literal">D</code> also decomposes into
- two. The components each inherit the cluster value of their parent:
- </p>
+ because 1 is the minimum of the set {1,2}, which were the
+ cluster values of <code class="literal">B</code> and
+ <code class="literal">C</code>.
+ </p>
+<p>
+ Next, let us say that the <code class="literal">BC</code> ligature glyph
+ decomposes into three components, and <code class="literal">D</code> also
+ decomposes into two components. Whenever a cluster decomposes,
+ its components each inherit the cluster value of their parent:
+ </p>
<pre class="programlisting">
- A,BC0,BC1,BC2,D0,D1,E
- 0,1 ,1 ,1 ,3 ,3 ,4
-</pre>
+ A,BC0,BC1,BC2,D0,D1,E
+ 0,1 ,1 ,1 ,3 ,3 ,4
+ </pre>
<p>
- Now if <code class="literal">BC2</code> and <code class="literal">D0</code> ligate, then
- their clusters (numbers 1 and 3) merge into
- <code class="literal">min(1,3) = 1</code>:
- </p>
+ Next, if <code class="literal">BC2</code> and <code class="literal">D0</code> form a
+ ligature, then their clusters (cluster values 1 and 3) merge into
+ <code class="literal">min(1,3) = 1</code>:
+ </p>
<pre class="programlisting">
- A,BC0,BC1,BC2D0,D1,E
- 0,1 ,1 ,1 ,1 ,4
-</pre>
+ A,BC0,BC1,BC2D0,D1,E
+ 0,1 ,1 ,1 ,1 ,4
+ </pre>
+<p>
+ Note that the entirety of cluster 3 merges into cluster 1, not
+ just the <code class="literal">D0</code> glyph. This reflects the fact
+ that the cluster <span class="emphasis"><em>must</em></span> be treated as an
+ indivisible unit.
+ </p>
<p>
- At this point, cluster 1 means: the character sequence
- <code class="literal">BCD</code> is represented by glyphs
- <code class="literal">BC0,BC1,BC2D0,D1</code> and cannot be broken down any
- further.
- </p>

+<p>
+ In contrast to OpenType shaping, AAT shaping does not specify a
+ predefined set of shaping models or a set of supported scripts.
+ </p>
+<p>
+ Instead, each AAT font includes a complete set of rules that
+ implement the desired shaping model for the intended
+ script. These rules include finite-state machines to match glyph
+ sequences and the shaping operations to perform.
+ </p>
+<p>
+ Notably, AAT shaping rules are expressed for glyphs in the font,
+ not for Unicode codepoints. AAT shaping can perform the same
+ shaping operations used in OpenType shaping, as well as other
+ functions that have not been defined for OpenType shaping.

+ and many others)
+ </p></li>
+<li class="listitem"><p>
+ Emoji (including emoji modifier sequences, flag sequences,
+ and ZWJ sequences)
+ </p></li>
+</ul></div>
+<p>
+ In addition to OpenType shaping, HarfBuzz supports the latest
+ version of Graphite shaping (the "Graphite 2" model) and AAT
+ shaping.
+ </p>
+<p>
+ HarfBuzz can read and understand TrueType fonts (.ttf), TrueType
+ collections (.ttc), and OpenType fonts (.otf, including those
+ fonts that contain TrueType-style outlines and those that
+ contain PostScript CFF or CFF2 outlines).
+ </p>
+<p>
+ HarfBuzz is designed and tested to run on top of the FreeType
+ font renderer. It can run on Linux, Android, Windows, macOS, and
+ iOS systems.
+ </p>
+<p>
+ In addition to its core shaping functionality, HarfBuzz provides
+ functions for accessing other font features, including optional
+ GSUB and GPOS OpenType features, as well as
+ all color-font formats (<code class="literal">CBDT</code>,
+ <code class="literal">sbix</code>, <code class="literal">COLR/CPAL</code>, and
+ <code class="literal">SVG-OT</code>) and OpenType variable fonts. HarfBuzz
+ also includes a font-subsetting feature. HarfBuzz can perform
+ some low-level math-shaping operations, although it does not
+ currently perform full shaping for mathematical typesetting.
+ </p>
+<p>
+ A suite of command-line utilities is also provided in the
+ source-code tree, designed to help users test and debug
+ HarfBuzz's features on real-world fonts and input.

+<p>
+ In text shaping, a <span class="emphasis"><em>script</em></span> is a
+ writing system: a set of symbols, rules, and conventions
+ that is used to represent a language or multiple
+ languages.
+ </p>
+<p>
+ In general computing lingo, the word "script" can also
+ be used to mean an executable program (usually one
+ written in a human-readable programming language). For
+ the sake of clarity, HarfBuzz documents will always use
+ more specific terminology when referring to this
+ meaning, such as "Python script" or "shell script." In
+ all other instances, "script" refers to a writing system.
+ </p>
+<p>
+ For developers using HarfBuzz, it is important to note
+ the distinction between a script and a language. Most
+ scripts are used to write a variety of different
+ languages, and many languages may be written in more
+ than one script.

+<td><p><span class="term">shaper</span></p></td>
+<td><p>
+ In HarfBuzz, a <span class="emphasis"><em>shaper</em></span> is a
+ handler for a specific script-shaping model. HarfBuzz
+ implements separate shapers for Indic, Arabic, Thai and
+ Lao, Khmer, Myanmar, Tibetan, Hangul, Hebrew, the
+ Universal Shaping Engine (USE), and a default shaper for
+ non-complex scripts.
+ </p></td>
+</tr>
+<tr>
+<td><p><span class="term">cluster</span></p></td>
+<td>
+<p>
+ In text shaping, a <span class="emphasis"><em>cluster</em></span> is a
+ sequence of codepoints that must be treated as an
+ indivisible unit. Clusters can include code-point
+ sequences that form a ligature or base-and-mark
+ sequences. Tracking and preserving clusters is important
+ when shaping operations might separate or reorder
+ code points.
+ </p>
+<p>
+ HarfBuzz provides three cluster
+ <span class="emphasis"><em>levels</em></span> that implement different
+ approaches to the problem of preserving clusters during
+ shaping operations.
+ </p>
+</td>
+</tr>
+<tr>
+<td><p><span class="term">grapheme</span></p></td>
+<td>
+<p>
+ In linguistics, a <span class="emphasis"><em>grapheme</em></span> is one
+ of the indivisible units that make up a writing system or
+ script. Often, graphemes are individual symbols (letters,
+ numbers, punctuation marks, logograms, etc.) but,
+ depending on the writing system, a particular grapheme
+ might correspond to a sequence of several Unicode code
+ points.
+ </p>
+<p>
+ In practice, HarfBuzz and other text-shaping engines
+ are not generally concerned with graphemes. However, it
+ is important for developers using HarfBuzz to recognize
+ that there is a difference between graphemes and shaping
+ clusters (see above). The two concepts may overlap
+ frequently, but there is no guarantee that they will be
+ identical.
+ </p>
+</td>
+</tr>
+<tr>
+<td><p><span class="term">syllable</span></p></td>
+<td>
+<p>
+ In linguistics, a <span class="emphasis"><em>syllable</em></span> is an
+ a sequence of sounds that makes up a building block of a
+ particular language. Every language has its own set of
+ rules describing what constitutes a valid syllable.
+ </p>
+<p>
+ For text-shaping purposes, the various definitions of
+ "syllable" are important because script-specific shaping
+ operations may be applied at the syllable level. For
+ example, a reordering rule might specify that a vowel
+ mark be reordered to the beginning of the syllable.
+ </p>
+<p>
+ Syllables will consist of one or more Unicode code
+ points. The definition of a syllable for a particular
+ writing system might correspond to how HarfBuzz
+ identifies clusters (see above) for the same writing
+ system. However, it is important for developers using
+ HarfBuzz to recognize that there is a difference between
+ syllables and shaping clusters. The two concepts may
+ overlap frequently, but there is no guarantee that they
+ will be identical.

<p>
- In shaping text, a <span class="emphasis"><em>cluster</em></span> is a sequence of
- code points that needs to be treated as a single, indivisible unit.
- </p>
+ In text shaping, a <span class="emphasis"><em>cluster</em></span> is a sequence of
+ characters that needs to be treated as a single, indivisible
+ unit. A single letter or symbol can be a cluster of its
+ own. Other clusters correspond to longer subsequences of the
+ input code points — such as a ligature or conjunct form
+ — and require the shaper to ensure that the cluster is not
+ broken during the shaping process.
+ </p>
<p>
- When you add text to a HB buffer, each character is associated with
- a <span class="emphasis"><em>cluster value</em></span>. This is an arbitrary number as
- far as HB is concerned.
- </p>
+ A cluster is distinct from a <span class="emphasis"><em>grapheme</em></span>,
+ which is the smallest unit of meaning in a writing system or
+ script.
+ </p>
<p>
- Most clients will use UTF-8, UTF-16, or UTF-32 indices, but the
- actual number does not matter. Moreover, it is not required for the
- cluster values to be monotonically increasing, but pretty much all
- of HB's tests are performed on monotonically increasing cluster
- numbers. Nevertheless, there is no such assumption in the code
- itself. With that in mind, let's examine what happens with cluster
- values during shaping under each cluster-level.
- </p>
+ The definitions of the two terms are similar. However, clusters
+ are only relevant for script shaping and glyph layout. In
+ contrast, graphemes are a property of the underlying script, and
+ are of interest when client programs implement orthographic
+ or linguistic functionality.
+ </p>
<p>
- HarfBuzz provides three <span class="emphasis"><em>levels</em></span> of clustering
- support. Level 0 is the default behavior and reproduces the behavior
- of the old HarfBuzz library. Level 1 tweaks this behavior slightly
- to produce better results, so level 1 clustering is recommended for
- code that is not required to implement backward compatibility with
- the old HarfBuzz.
- </p>
+ For example, two individual letters are often two separate
+ graphemes. When two letters form a ligature, however, they
+ combine into a single glyph. They are then part of the same
+ cluster and are treated as a unit by the shaping engine —
+ even though the two original, underlying letters remain separate
+ graphemes.
+ </p>
<p>
- Level 2 differs significantly in how it treats cluster values.
- Levels 0 and 1 both process ligatures and glyph decomposition by
- merging clusters; level 2 does not.
- </p>
+ HarfBuzz is concerned with clusters, <span class="emphasis"><em>not</em></span>
+ with graphemes — although client programs using HarfBuzz
+ may still care about graphemes for other reasons from time to time.
+ </p>
<p>
- The conceptual model for what the cluster values mean, in levels 0
- and 1, is this:
- </p>
-<div class="itemizedlist"><ul class="itemizedlist compact" style="list-style-type: disc; ">
+ During the shaping process, there are several shaping operations
+ that may merge adjacent characters (for example, when two code
+ points form a ligature or a conjunct form and are replaced by a
+ single glyph) or split one character into several (for example,
+ when decomposing a code point through the
+ <code class="literal">ccmp</code> feature). Operations like these alter
+ clusters; HarfBuzz tracks the changes to ensure that no clusters
+ get lost or broken during shaping.
+ </p>
+<p>
+ HarfBuzz records cluster information independently from how
+ shaping operations affect the individual glyphs returned in an
+ output buffer. Consequently, a client program using HarfBuzz can
+ utilize the cluster information to implement features such as:
+ </p>
+<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
+<li class="listitem"><p>
+ Correctly positioning the cursor within a shaped text run,
+ even when characters have formed ligatures, composed or
+ decomposed, reordered, or undergone other shaping operations.
+ </p></li>
<li class="listitem"><p>
- the sequence of cluster values will always remain monotone
- </p></li>
+ Correctly highlighting a text selection that includes some,
+ but not all, of the characters in a word.
+ </p></li>
<li class="listitem"><p>
- each value represents a single cluster
- </p></li>
+ Applying text attributes (such as color or underlining) to
+ part, but not all, of a word.
+ </p></li>
<li class="listitem"><p>
- each cluster contains one or more glyphs and one or more
- characters
- </p></li>
+ Generating output document formats (such as PDF) with
+ embedded text that can be fully extracted.
+ </p></li>
+<li class="listitem"><p>
+ Determining the mapping between input characters and output
+ glyphs, such as which glyphs are ligatures.
+ </p></li>
+<li class="listitem"><p>
+ Performing line-breaking, justification, and other
+ line-level or paragraph-level operations that must be done
+ after shaping is complete, but which require examining
+ character-level properties.
+ </p></li>
</ul></div>
-<p>
- Assuming that initial cluster numbers were monotonically increasing
- and distinct, then all adjacent glyphs having the same cluster
- number belong to the same cluster, and all characters belong to the
- cluster that has the highest number not larger than their initial
- cluster number. This will become clearer with an example.

+<p>
+ In text-shaping terminology, scripts are generally classified as
+ either <span class="emphasis"><em>complex</em></span> or <span class="emphasis"><em>non-complex</em></span>.
+ </p>
+<p>
+ Complex scripts are those for which transforming the input
+ sequence into the final layout requires some combination of
+ operations—such as context-dependent substitutions,
+ context-dependent mark positioning, glyph-to-glyph joining,
+ glyph reordering, or glyph stacking.
+ </p>
+<p>
+ In some complex scripts, the shaping rules require that a text
+ run be divided into syllables before the operations can be
+ applied. Other complex scripts may apply shaping operations over
+ entire words or over the entire text run, with no subdivision
+ required.
+ </p>
+<p>
+ Non-complex scripts, by definition, do not require these
+ operations. However, correctly shaping a text run in a
+ non-complex script may still involve Unicode normalization,
+ ligature substitutions, mark positioning, kerning, and applying
+ other font features. The key difference is that a text run in a
+ non-complex script can be processed sequentially and in the same
+ order as the input sequence of Unicode codepoints, without
+ requiring an analysis stage.

+<p>
+ The core of the HarfBuzz shaping API is the function
+ <code class="function">hb_shape()</code>. This function takes a font, a
+ buffer containing a string of Unicode codepoints and
+ (optionally) a list of font features as its input. It replaces
+ the codepoints in the buffer with the corresponding glyphs from
+ the font, correctly ordered and positioned, and with any of the
+ optional font features applied.
+ </p>
+<p>
+ In addition to holding the pre-shaping input (the Unicode
+ codepoints that comprise the input string) and the post-shaping
+ output (the glyphs and positions), a HarfBuzz buffer has several
+ properties that affect shaping. The most important are the
+ text-flow direction (e.g., left-to-right, right-to-left,
+ top-to-bottom, or bottom-to-top), the script tag, and the
+ language tag.
+ </p>
+<p>
+ For input string buffers, flags are available to denote when the
+ buffer represents the beginning or end of a paragraph, to
+ indicate whether or not to visibly render Unicode <code class="literal">Default
+ Ignorable</code> codepoints, and to modify the cluster-merging
+ behavior for the buffer. For shaped output buffers, the
+ individual X and Y offsets and <code class="literal">advances</code>
+ (the logical dimensions) of each glyph are
+ accessible. HarfBuzz also flags glyphs as
+ <code class="literal">UNSAFE_TO_BREAK</code> if breaking the string at
+ that glyph (e.g., in a line-breaking or hyphenation process)
+ would require re-shaping the text.
+ </p>
+<p>
+ HarfBuzz also provides methods to compare the contents of
+ buffers, join buffers, normalize buffer contents, and handle
+ invalid codepoints, as well as to determine the state of a
+ buffer (e.g., input codepoints or output glyphs). Buffer
+ lifecycles are managed and all buffers are reference-counted.
+ </p>
+<p>
+ Although the default <code class="function">hb_shape()</code> function is
+ sufficient for most use cases, a variant is also provide that
+ lets you specify which of HarfBuzz's shapers to use on a buffer.
+ </p>
+<p>
+ HarfBuzz can read TrueType fonts, TrueType collections, OpenType
+ fonts, and OpenType collections. Functions are provided to query
+ font objects about metrics, Unicode coverage, available tables and
+ features, and variation selectors. Individual glyphs can also be
+ queried for metrics, variations, and glyph names. OpenType
+ variable fonts are supported, and HarfBuzz allows you to set
+ variation-axis coordinates on font objects.
+ </p>
+<p>
+ HarfBuzz provides glue code to integrate with various other
+ libraries, including FreeType, GObject, and CoreText. Support
+ for integrating with Uniscribe and DirectWrite is experimental
+ at present.

+<p>
+ In contrast to OpenType shaping, Graphite shaping does not
+ specify a predefined set of shaping models or a set of supported
+ scripts.
+ </p>
+<p>
+ Instead, each Graphite font contains a complete set of rules that
+ implement the required shaping model for the intended
+ script. These rules include finite-state machines to match
+ sequences of codepoints to the shaping operations to perform.
+ </p>
+<p>
+ Graphite shaping can perform the same shaping operations used in
+ OpenType shaping, as well as other functions that have not been
+ defined for OpenType shaping.

-<p>
- The code above will take a UTF8 string, shape it, and give you the
- information required to lay it out correctly on a single
- horizontal (or vertical) line using the font provided. That is the
- extent of HarfBuzz's responsibility.
- </p>
-<p>
- If you are implementing a text layout engine you may have other
- responsibilities, that HarfBuzz will not help you with:
- </p>
-<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
-<li class="listitem">
-<p>
- HarfBuzz won't help you with bidirectionality. If you want to
- lay out text with mixed Hebrew and English, you will need to
- ensure that the buffer provided to HarfBuzz has those
- characters in the correct layout order. This will be different
- from the logical order in which the Unicode text is stored. In
- other words, the user will hit the keys in the following
- sequence:
- </p>
-<pre class="programlisting">
-A B C [space] ג ב א [space] D E F
- </pre>
-<p>
- but will expect to see in the output:
- </p>
-<pre class="programlisting">
-ABC אבג DEF
- </pre>
-<p>
- This reordering is called <span class="emphasis"><em>bidi processing</em></span>
- ("bidi" is short for bidirectional), and there's an
- algorithm as an annex to the Unicode Standard which tells you how
- to reorder a string from logical order into presentation order.
- Before sending your string to HarfBuzz, you may need to apply the
- bidi algorithm to it. Libraries such as ICU and fribidi can do
- this for you.
- </p>
-</li>
-<li class="listitem"><p>
- HarfBuzz won't help you with text that contains different font
- properties. For instance, if you have the string "a
- <span class="emphasis"><em>huge</em></span> breakfast", and you expect
- "huge" to be italic, you will need to send three
- strings to HarfBuzz: <code class="literal">a</code>, in your Roman font;
- <code class="literal">huge</code> using your italic font; and
- <code class="literal">breakfast</code> using your Roman font again.
- Similarly if you change font, font size, script, language or
- direction within your string, you will need to shape each run
- independently and then output them independently. HarfBuzz
- expects to shape a run of characters sharing the same
- properties.
- </p></li>
-<li class="listitem">
-<p>
- HarfBuzz won't help you with line breaking, hyphenation or
- justification. As mentioned above, it lays out the string
- along a <span class="emphasis"><em>single line</em></span> of, notionally,
- infinite length. If you want to find out where the potential
- word, sentence and line break points are in your text, you
- could use the ICU library's break iterator functions.
- </p>
-<p>
- HarfBuzz can tell you how wide a shaped piece of text is, which is
- useful input to a justification algorithm, but it knows nothing
- about paragraphs, lines or line lengths. Nor will it adjust the
- space between words to fit them proportionally into a line. If you
- want to layout text in paragraphs, you will probably want to send
- each word of your text to HarfBuzz to determine its shaped width
- after glyph substitutions, then work out how many words will fit
- on a line, and then finally output each word of the line separated
- by a space of the correct size to fully justify the paragraph.
- </p>
-</li>
-</ul></div>
-<p>
- As a layout engine implementor, HarfBuzz will help you with the
- interface between your text and your font, and that's something
- that you'll need - what you then do with the glyphs that your font
- returns is up to you. The example we saw above enough to get us
- started using HarfBuzz. Now we are going to use the remainder of
- HarfBuzz's API to refine that example and improve our text shaping
- capabilities.

<a name="level-2"></a>Level 2</h2></div></div></div>
<p>
- Level 2 is a different beast from levels 0 and 1. It is simple to
- describe, but hard to make sense of. It simply doesn't do any
- cluster merging whatsoever. When things ligate or otherwise multiple
- glyphs turn into one, the cluster value of the first glyph is
- retained.
- </p>
-<p>
- Here are a few examples of why processing cluster values produced at
- this level might be tricky:
- </p>
-<div class="sect2">
-<div class="titlepage"><div><div><h3 class="title">
-<a name="ligatures-with-combining-marks"></a>Ligatures with combining marks</h3></div></div></div>
+ HarfBuzz's level 2 cluster behavior uses a significantly
+ different model than that of level 0 and level 1.
+ </p>
<p>
- Imagine capital letters are bases and lower case letters are
- combining marks. With an input sequence like this:
+ The level 2 behavior is easy to describe, but it may be
+ difficult to understand in practical terms. In brief, level 2
+ performs no merging of clusters whatsoever.
</p>
-<pre class="programlisting">
- A,a,B,b,C,c
- 0,1,2,3,4,5
-</pre>
<p>
- if <code class="literal">A,B,C</code> ligate, then here are the cluster
- values one would get under the various levels:
+ This means that there is no initial base-and-mark merging step
+ (as is done in level 0), and it means that reordering moves and
+ ligature substitutions do not trigger a cluster merge.
</p>
<p>
- level 0:
+ Only one shaping operation directly affects clusters when using
+ level 2:
</p>
-<pre class="programlisting">
- ABC,a,b,c
- 0 ,0,0,0
-</pre>
+<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
+ When a cluster <span class="emphasis"><em>decomposes</em></span>, all of the
+ resulting child clusters inherit as their cluster value the
+ cluster value of the parent cluster.
+ </p></li></ul></div>
<p>
- level 1:
+ When glyphs do form a ligature (or when some other feature
+ substitutes multiple glyphs with one glyph) the cluster value
+ of the first glyph is retained as the cluster value for the
+ resulting ligature.
</p>
-<pre class="programlisting">
- ABC,a,b,c
- 0 ,0,0,5
-</pre>
<p>
- level 2:
+ This occurrence sounds similar to a cluster merge, but it is
+ different. In particular, no subsequent characters —
+ including marks and modifiers — are affected. They retain
+ their previous cluster values.
</p>
-<pre class="programlisting">
- ABC,a,b,c
- 0 ,1,3,5
-</pre>
-<p>
- Making sense of the last example is the hardest for a client,
- because there is nothing in the cluster values to suggest that
- <code class="literal">B</code> and <code class="literal">C</code> ligated with
- <code class="literal">A</code>.
+<p>
+ Level 2 cluster behavior is ultimately less complex than level 0
+ or level 1, but there are several cases for which processing
+ cluster values produced at level 2 may be tricky.
</p>
+<div class="section">
+<div class="titlepage"><div><div><h3 class="title">
+<a name="ligatures-with-combining-marks-in-level-2"></a>Ligatures with combining marks in level 2</h3></div></div></div>
+<p>
+ The first example of how HarfBuzz's level 2 cluster behavior
+ can be tricky is when the text to be shaped includes combining
+ marks attached to ligatures.
+ </p>
+<p>
+ Let us start with an input sequence with the following
+ characters (top row) and initial cluster values (bottom row):
+ </p>
+<pre class="programlisting">
+ A,acute,B,breve,C,circumflex
+ 0,1 ,2,3 ,4,5
+ </pre>
+<p>
+ If the sequence <code class="literal">A,B,C</code> forms a ligature,
+ then these are the cluster values HarfBuzz will return under
+ the various cluster levels:
+ </p>
+<p>
+ Level 0:
+ </p>
+<pre class="programlisting">
+ ABC,acute,breve,circumflex
+ 0 ,0 ,0 ,0
+ </pre>
+<p>
+ Level 1:
+ </p>
+<pre class="programlisting">
+ ABC,acute,breve,circumflex
+ 0 ,0 ,0 ,5
+ </pre>
+<p>
+ Level 2:
+ </p>
+<pre class="programlisting">
+ ABC,acute,breve,circumflex
+ 0 ,1 ,3 ,5
+ </pre>
+<p>
+ Making sense of the level 2 result is the hardest for a client
+ program, because there is nothing in the cluster values that
+ indicates that <code class="literal">B</code> and <code class="literal">C</code>
+ formed a ligature with <code class="literal">A</code>.
+ </p>
+<p>
+ In contrast, the "merged" cluster values of the mark glyphs
+ that are seen in the level 0 and level 1 output are evidence
+ that a ligature substitution took place.
+ </p>
</div>
-<div class="sect2">
+<div class="section">
<div class="titlepage"><div><div><h3 class="title">
-<a name="reordering"></a>Reordering</h3></div></div></div>
+<a name="reordering-in-level-2"></a>Reordering in level 2</h3></div></div></div>
<p>
- Another tricky case is when things reorder. Under level 2:
- </p>
+ Another example of how HarfBuzz's level 2 cluster behavior
+ can be tricky is when glyphs reorder. Consider an input sequence
+ with the following characters (top row) and initial cluster
+ values (bottom row):
+ </p>
<pre class="programlisting">
- A,B,C,D,E
- 0,1,2,3,4
-</pre>
+ A,B,C,D,E
+ 0,1,2,3,4
+ </pre>
<p>
- Now imagine <code class="literal">D</code> moves before
- <code class="literal">B</code>:
- </p>
+ Now imagine <code class="literal">D</code> moves before
+ <code class="literal">B</code> in a reordering operation. The cluster
+ values will then be:
+ </p>
<pre class="programlisting">
- A,D,B,C,E
- 0,3,1,2,4
-</pre>
+ A,D,B,C,E
+ 0,3,1,2,4
+ </pre>
<p>
- Now, if <code class="literal">D</code> ligates with <code class="literal">B</code>, we
- get:
- </p>
+ Next, if <code class="literal">D</code> forms a ligature with
+ <code class="literal">B</code>, the output is:
+ </p>
<pre class="programlisting">
- A,DB,C,E
- 0,3 ,2,4
-</pre>
-<p>
- In a different scenario, <code class="literal">A</code> and
- <code class="literal">B</code> could have ligated
- <span class="emphasis"><em>before</em></span> <code class="literal">D</code> reordered; that
- would have resulted in:
- </p>
+ A,DB,C,E
+ 0,3 ,2,4
+ </pre>
+<p>
+ However, in a different scenario, in which the shaping rules
+ of the script instead caused <code class="literal">A</code> and
+ <code class="literal">B</code> to form a ligature
+ <span class="emphasis"><em>before</em></span> the <code class="literal">D</code> reordered, the
+ result would be:
+ </p>
<pre class="programlisting">
- AB,D,C,E
- 0 ,3,2,4
-</pre>
+ AB,D,C,E
+ 0 ,3,2,4
+ </pre>
<p>
- There's no way to differentiate between these two scenarios based
- on the cluster numbers alone.
- </p>
+ There is no way for a client program to differentiate between
+ these two scenarios based on the cluster values
+ alone. Consequently, client programs that use level 2 might
+ need to undertake additional work in order to manage cursor
+ positioning, text attributes, or other desired features.

- Another problem happens with ligatures under level 2 if the
- direction of the text is forced to opposite of its natural
- direction (e.g. left-to-right Arabic). But that's too much of a
- corner case to worry about.
- </p>
+ There may be other problems encountered with ligatures under
+ level 2, such as if the direction of the text is forced to
+ opposite of its natural direction (for example, Arabic text
+ that is forced into left-to-right directionality). But,
+ generally speaking, these other scenarios are minor corner
+ cases that are too obscure for most client programs to need to
+ worry about.

+ Malayalam, Oriya, Tamil, Telugu, and Sinhala.
+ </p>
+<p>
+ The Indic shaping model was revised significantly in

+<p>
+ Prior to 2012, the original HarfBuzz codebase (which, these

- Another common operation in the more complex shapers is when things
- reorder. In those cases, to maintain monotone clusters, HB merges
- the clusters of everything in the reordering sequence. For example,
- let's again start with the character sequence:
- </p>
+ Another common operation in the more complex shapers is glyph
+ reordering. In order to maintain a monotonic cluster sequence
+ when glyph reordering takes place, HarfBuzz merges the clusters
+ of everything in the reordering sequence.
+ </p>
+<p>
+ For example, let us again start with the character sequence (top
+ row) and initial cluster values (bottom row):
+ </p>
<pre class="programlisting">
- A,B,C,D,E
- 0,1,2,3,4
-</pre>
+ A,B,C,D,E
+ 0,1,2,3,4
+ </pre>
<p>
- If <code class="literal">D</code> is reordered before <code class="literal">B</code>,
- then the <code class="literal">B</code>, <code class="literal">C</code>, and
- <code class="literal">D</code> clusters merge, and we get:
- </p>
+ If <code class="literal">D</code> is reordered to the position immediately
+ before <code class="literal">B</code>, then HarfBuzz merges the
+ <code class="literal">B</code>, <code class="literal">C</code>, and
+ <code class="literal">D</code> clusters — all the clusters between
+ the final position of the reordered glyph and its original
+ position. This means that we get:
+ </p>
<pre class="programlisting">
- A,D,B,C,E
- 0,1,1,1,4
-</pre>
+ A,D,B,C,E
+ 0,1,1,1,4
+ </pre>
+<p>
+ as the final cluster sequence.
+ </p>
<p>
- This is clearly not ideal, but it is the only sensible way to
- maintain monotone indices and retain the true relationship between
- glyphs and characters.
- </p>
+ Merging this many clusters is not ideal, but it is the only
+ sensible way for HarfBuzz to maintain the guarantee that the
+ sequence of cluster values remains monotonic and to retain the
+ true relationship between glyphs and characters.
+ </p>

+ Text shaping is the process of transforming a sequence of Unicode
+ codepoints that represent individual characters (letters,
+ diacritics, tone marks, numbers, symbols, etc.) into the
+ orthographically and linguistically correct two-dimensional layout
+ of glyph shapes taken from a specified font.
+ </p>
+<p>
+ For some writing systems (or <span class="emphasis"><em>scripts</em></span>) and
+ languages, the process is simple, requiring the shaper to do
+ little more than advance the horizontal position forward by the
+ correct amount for each successive glyph.
+ </p>
+<p>
+ But, for <span class="emphasis"><em>complex scripts</em></span>, any combination of
+ several shaping operations may be required, and the rules for how
+ and when they are applied vary from script to script. HarfBuzz and
+ other shaping engines implement these rules.
+ </p>
+<p>
+ The exact rules and necessary operations for a particular script
+ constitute a shaping <span class="emphasis"><em>model</em></span>. OpenType
+ specifies a set of shaping models that covers all of
+ Unicode. Other shaping models are available, however, including
+ Graphite and Apple Advanced Typography (AAT).

<p>
- So, the above is pretty much what cluster levels 0 and 1 do. The
- only difference between the two is this: in level 0, at the very
- beginning of the shaping process, we also merge clusters between
- base characters and all Unicode marks (combining or not) following
- them. E.g.:
- </p>
+ The preceding examples demonstrate the main effects of using
+ cluster levels 0 and 1. The only difference between the two
+ levels is this: in level 0, at the very beginning of the shaping
+ process, HarfBuzz merges the cluster of each base character
+ with the clusters of all Unicode marks (combining or not) and
+ modifiers that follow it.
+ </p>
+<p>
+ For example, let us start with the following character sequence
+ (top row) and accompanying initial cluster values (bottom row):
+ </p>
<pre class="programlisting">
- A,acute,B
- 0,1 ,2
-</pre>
+ A,acute,B
+ 0,1 ,2
+ </pre>
<p>
- will become:
- </p>
+ The <code class="literal">acute</code> is a Unicode mark. If HarfBuzz is
+ using cluster level 0 on this sequence, then the
+ <code class="literal">A</code> and <code class="literal">acute</code> clusters will
+ merge, and the result will become:
+ </p>
<pre class="programlisting">
- A,acute,B
- 0,0 ,2
-</pre>
+ A,acute,B
+ 0,0 ,2
+ </pre>
+<p>
+ This merger is performed before any other script-shaping
+ steps.
+ </p>
+<p>
+ This initial cluster merging is the default behavior of the
+ Windows shaping engine, and the old HarfBuzz codebase copied
+ that behavior to maintain compatibility. Consequently, it has
+ remained the default behavior in the new HarfBuzz codebase.
+ </p>
+<p>
+ But this initial cluster-merging behavior makes it impossible
+ client programs to implement some features (such as to
+ color diacritic marks differently from their base
+ characters). That is why, in level 1, HarfBuzz does not perform
+ the initial merging step.
+ </p>
<p>
- This is the default behavior. We do it because Windows did it and
- old HarfBuzz did it, so this remained the default. But this behavior
- makes it impossible to color diacritic marks differently from their
- base characters. That's why in level 1 we do not perform this
- initial merging step.
- </p>
+ For client programs that rely on HarfBuzz cluster values to
+ perform cursor positioning, level 0 is more convenient. But
+ relying on cluster boundaries for cursor positioning is wrong: cursor
+ positions should be determined based on Unicode grapheme
+ boundaries, not on shaping-cluster boundaries. As such, using
+ level 1 clustering behavior is recommended.
+ </p>
<p>
- For clients, level 0 is more convenient if they rely on HarfBuzz
- clusters for cursor positioning. But that's wrong anyway: cursor
- positions should be determined based on Unicode grapheme boundaries,
- NOT shaping clusters. As such, level 1 clusters are preferred.
- </p>
+ One final facet of levels 0 and 1 is worth noting. HarfBuzz
+ currently does not allow any
+ <span class="emphasis"><em>multiple-substitution</em></span> GSUB lookups to
+ replace a glyph with zero glyphs (in other words, to delete a
+ glyph).
+ </p>
<p>
- One last note about levels 0 and 1. We currently don't allow a
- <code class="literal">MultipleSubst</code> lookup to replace a glyph with zero
- glyphs (i.e., to delete a glyph). But in some other situations,
- glyphs can be deleted. In those cases, if the glyph being deleted is
- the last glyph of its cluster, we make sure to merge the cluster
- with a neighboring cluster.
- </p>
+ But, in some other situations, glyphs can be deleted. In
+ those cases, if the glyph being deleted is the last glyph of its
+ cluster, HarfBuzz makes sure to merge the deleted glyph's
+ cluster with a neighboring cluster.
+ </p>
<p>
- This is, primarily, to make sure that the starting cluster of the
- text always has the cluster index pointing to the start of the text
- for the run; more than one client currently relies on this
- guarantee.

<p>
- Incidentally, Apple's CoreText does something else to maintain the
- same promise: it inserts a glyph with id 65535 at the beginning of
- the glyph string if the glyph corresponding to the first character
- in the run was deleted. HarfBuzz might do something similar in the
- future.

+<p>
+ Shaping models are typically specified with respect to how
+ scripts are defined in the Unicode standard.
+ </p>
+<p>
+ Every codepoint in the Unicode Character Database (UCD) is
+ assigned a <span class="emphasis"><em>Unicode General Category</em></span> (UGC),
+ which provides the most fundamental information about the
+ codepoint: whether the codepoint represents a
+ <span class="emphasis"><em>Letter</em></span>, a <span class="emphasis"><em>Mark</em></span>, a
+ <span class="emphasis"><em>Number</em></span>, <span class="emphasis"><em>Punctuation</em></span>, a
+ <span class="emphasis"><em>Symbol</em></span>, a <span class="emphasis"><em>Separator</em></span>,
+ or something else (<span class="emphasis"><em>Other</em></span>).
+ </p>
+<p>
+ These UGC properties are "Major" categories. Each codepoint is
+ further assigned to a "minor" category within its Major
+ category, such as "Letter, uppercase" (<code class="literal">Lu</code>) or
+ "Letter, modifier" (<code class="literal">Lm</code>).
+ </p>
+<p>
+ Shaping models are concerned primarily with Letter and Mark
+ codepoints. The minor categories of Mark codepoints are
+ particularly important for shaping. Marks can be nonspacing
+ (<code class="literal">Mn</code>), spacing combining
+ (<code class="literal">Mc</code>), or enclosing (<code class="literal">Me</code>).
+ </p>
+<p>
+ In addition to the UGC property, codepoints in the Indic and
+ Southeast Asian scripts are also assigned
+ <span class="emphasis"><em>Unicode Indic Syllabic Category</em></span> (UISC) and
+ <span class="emphasis"><em>Unicode Indic Positional Category</em></span> (UIPC)
+ properties that provide more detailed information needed for
+ shaping.
+ </p>
+<p>
+ The UISC property sub-categorizes Letters and Marks according to
+ common script-shaping behaviors. For example, UISC distinguishes
+ between consonant letters, vowel letters, and vowel marks. The
+ UIPC property sub-categorizes Mark codepoints by the relative visual
+ position that they occupy (above, below, right, left, or in
+ multiple positions).
+ </p>
+<p>
+ Some complex scripts require that the text run be split into
+ syllables. What constitutes a valid syllable in these
+ scripts is specified in regular expressions, formed from the
+ Letter and Mark codepoints, that take the UISC and UIPC
+ properties into account.

+ </p>
+<p>
+ It is important to note that if you are implementing a complete

+ HarfBuzz won't help you with bidirectionality. If you want to
+ lay out text that includes a mix of Hebrew and English, you
+ will need to ensure that each buffer provided to HarfBuzz
+ has all of its characters in the same order and that the
+ directionality of the buffer is set correctly. This may mean
+ segmenting the text before it is placed into HarfBuzz buffers. In

+ properties. For instance, if you have the string "a
+ <span class="emphasis"><em>huge</em></span> breakfast", and you expect
+ "huge" to be italic, then you will need to send three
+ strings to HarfBuzz: <code class="literal">a</code>, in your Roman font;
+ <code class="literal">huge</code> using your italic font; and
+ <code class="literal">breakfast</code> using your Roman font again.
+ </p>
+<p>
+ Similarly, if you change the font, font size, script,
+ language, or direction within your string, then you will
+ need to shape each run independently and output them
+ independently. HarfBuzz expects to shape a run of characters
+ that all share the same properties.
+ </p>
+</li>
+<li class="listitem">
+<p>
+ HarfBuzz won't help you with line breaking, hyphenation, or
+ justification. As mentioned above, HarfBuzz lays out the string
+ along a <span class="emphasis"><em>single line</em></span> of, notionally,
+ infinite length. If you want to find out where the potential
+ word, sentence and line break points are in your text, you
+ could use the ICU library's break iterator functions.
+ </p>
+<p>
+ HarfBuzz can tell you how wide a shaped piece of text is, which is
+ useful input to a justification algorithm, but it knows nothing
+ about paragraphs, lines or line lengths. Nor will it adjust the
+ space between words to fit them proportionally into a line.
+ </p>
+</li>
+</ul></div>
+<p>
+ As a layout-engine implementor, HarfBuzz will help you with the
+ interface between your text and your font, and that's something
+ that you'll need—what you then do with the glyphs that your font
+ returns is up to you.

- HarfBuzz is a <span class="emphasis"><em>text shaping engine</em></span>. It solves
- the problem of selecting and positioning glyphs from a font given a
- Unicode string.
+ HarfBuzz is a <span class="emphasis"><em>text-shaping engine</em></span>. If you
+ give HarfBuzz a font and a string containing a sequence of Unicode
+ codepoints, HarfBuzz selects and positions the corresponding
+ glyphs from the font, applying all of the necessary layout rules
+ and font features. HarfBuzz then returns the string to you in the
+ form that is correctly arranged for the language and writing
+ system.
+ </p>
+<p>
+ HarfBuzz can properly shape all of the world's major writing
+ systems. It runs on all major operating systems and software
+ platforms and it supports the major font formats in use
+ today.

+<p>
+ Text shaping is the process of translating a string of character
+ codes (such as Unicode codepoints) into a properly arranged
+ sequence of glyphs that can be rendered onto a screen or into
+ final output form for inclusion in a document.
+ </p>
+<p>
+ The shaping process is dependent on the input string, the active
+ font, the script (or writing system) that the string is in, and
+ the language that the string is in.
+ </p>
+<p>
+ Modern software systems generally only deal with strings in the
+ Unicode encoding scheme (although legacy systems and documents may
+ involve other encodings).
+ </p>
+<p>
+ There are several font formats that a program might
+ encounter, each of which has a set of standard text-shaping
+ rules.
+ </p>
+<p>The dominant format is <a class="ulink" href="http://www.microsoft.com/typography/otspec/" target="_top">OpenType</a>. The
+ OpenType specification defines a series of <a class="ulink" href="https://github.com/n8willis/opentype-shaping-documents" target="_top">shaping models</a> for
+ various scripts from around the world. These shaping models depend on
+ the font incorporating certain features as
+ <span class="emphasis"><em>lookups</em></span> in its <code class="literal">GSUB</code>
+ and <code class="literal">GPOS</code> tables.
+ </p>
<p>
- Text shaping is an integral part of preparing text for display. It
- is a fairly low level operation; HarfBuzz is used directly by
- graphic rendering libraries such as Pango, and the layout engines
- in Firefox, LibreOffice and Chromium. Unless you are
- <span class="emphasis"><em>writing</em></span> one of these layout engines yourself,
- you will probably not need to use HarfBuzz - normally higher level
- libraries will turn text into glyphs for you.
+ Alternatively, OpenType fonts can include shaping features for
+ the <a class="ulink" href="https://graphite.sil.org/" target="_top">Graphite</a> shaping model.
</p>
<p>
- However, if you <span class="emphasis"><em>are</em></span> writing a layout engine
- or graphics library yourself, you will need to perform text
- shaping, and this is where HarfBuzz can help you. Here are some
- reasons why you need it:
+ TrueType fonts can also include OpenType shaping
+ features. Alternatively, TrueType fonts can also include <a class="ulink" href="https://developer.apple.com/fonts/TrueType-Reference-Manual/RM09/AppendixF.html" target="_top">Apple
+ Advanced Typography</a> (AAT) tables to implement shaping
+ support. AAT fonts are generally only found on macOS and iOS systems.
</p>
-<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
-<li class="listitem"><p>
- OpenType fonts contain a set of glyphs, indexed by glyph ID.
- The glyph ID within the font does not necessarily relate to a
- Unicode codepoint. For instance, some fonts have the letter
- "a" as glyph ID 1. To pull the right glyph out of
- the font in order to display it, you need to consult a table
- within the font (the "cmap" table) which maps
- Unicode codepoints to glyph IDs. Text shaping turns codepoints
- into glyph IDs.
- </p></li>
-<li class="listitem"><p>
- Many OpenType fonts contain ligatures: combinations of
- characters which are rendered together. For instance, it's
- common for the <code class="literal">fi</code> combination to appear in
- print as the single ligature "fi". Whether you should
- render text as <code class="literal">fi</code> or "fi" does not
- depend on the input text, but on the capabilities of the font
- and the level of ligature application you wish to perform.
- Text shaping involves querying the font's ligature tables and
- determining what substitutions should be made.
- </p></li>
-<li class="listitem"><p>
- While ligatures like "fi" are typographic
- refinements, some languages <span class="emphasis"><em>require</em></span> such
- substitutions to be made in order to display text correctly.
- In Tamil, when the letter "TTA" (ட) letter is
- followed by "U" (உ), the combination should appear
- as the single glyph "டு". The sequence of Unicode
- characters "டஉ" needs to be rendered as a single
- glyph from the font - text shaping chooses the correct glyph
- from the sequence of characters provided.
- </p></li>
-<li class="listitem"><p>
- Similarly, each Arabic character has four different variants:
- within a font, there will be glyphs for the initial, medial,
- final, and isolated forms of each letter. Unicode only encodes
- one codepoint per character, and so a Unicode string will not
- tell you which glyph to use. Text shaping chooses the correct
- form of the letter and returns the correct glyph from the font
- that you need to render.
- </p></li>
-<li class="listitem"><p>
- Other languages have marks and accents which need to be
- rendered in certain positions around a base character. For
- instance, the Moldovan language has the Cyrillic letter
- "zhe" (ж) with a breve accent, like so: ӂ. Some
- fonts will contain this character as an individual glyph,
- whereas other fonts will not contain a zhe-with-breve glyph
- but expect the rendering engine to form the character by
- overlaying the two glyphs ж and ˘. Where you should draw the
- combining breve depends on the height of the preceding glyph.
- Again, for Arabic, the correct positioning of vowel marks
- depends on the height of the character on which you are
- placing the mark. Text shaping tells you whether you have a
- precomposed glyph within your font or if you need to compose a
- glyph yourself out of combining marks, and if so, where to
- position those marks.
- </p></li>
-</ul></div>
<p>
- If this is something that you need to do, then you need a text
- shaping engine: you could use Uniscribe if you are using Windows;
- you could use CoreText on OS X; or you could use HarfBuzz. In the
- rest of this manual, we are going to assume that you are the
- implementor of a text layout engine.
+ Text strings will usually be tagged with a script and language
+ tag that provide the context needed to perform text shaping
+ correctly. The necessary <a class="ulink" href="https://docs.microsoft.com/en-us/typography/opentype/spec/scripttags" target="_top">script</a>
+ and <a class="ulink" href="https://docs.microsoft.com/en-us/typography/opentype/spec/languagetags" target="_top">language</a>
+ tags are defined by OpenType.

+<p>
+ Text shaping is an integral part of preparing text for
+ display. Before a Unicode sequence can be rendered, the
+ codepoints in the sequence must be mapped to the corresponding
+ glyphs provided in the font, and those glyphs must be positioned
+ correctly relative to each other. For many of the scripts
+ supported in Unicode, these steps involve script-specific layout
+ rules, including complex joining, reordering, and positioning
+ behavior. Implementing these rules is the job of the shaping engine.
+ </p>
+<p>
+ Text shaping is a fairly low-level operation. HarfBuzz is
+ used directly by text-handling libraries like <a class="ulink" href="https://www.pango.org/" target="_top">Pango</a>, as well as by the layout
+ engines in Firefox, LibreOffice, and Chromium. Unless you are
+ <span class="emphasis"><em>writing</em></span> one of these layout engines
+ yourself, you will probably not need to use HarfBuzz: normally,
+ a layout engine, toolkit, or other library will turn text into
+ glyphs for you.
+ </p>
+<p>
+ However, if you <span class="emphasis"><em>are</em></span> writing a layout engine
+ or graphics library yourself, then you will need to perform text
+ shaping, and this is where HarfBuzz can help you.
+ </p>
+<p>
+ Here are some specific scenarios where a text-shaping engine
+ like HarfBuzz helps you:
+ </p>
+<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">

+ OpenType fonts contain a set of glyphs (that is, shapes
+ to represent the letters, numbers, punctuation marks, and
+ all other symbols), which are indexed by a <code class="literal">glyph ID</code>.
+ </p>
+<p>
+ A particular glyph ID within the font does not necessarily
+ correlate to a predictable Unicode codepoint. For instance,
+ some fonts have the letter "a" as glyph ID 1, but
+ many others do not. In order to retrieve the right glyph
+ from the font to display "a", you need to consult

+ sequence to appear in print as the single ligature glyph
+ "fi".
+ </p>
+<p>
+ Whether you should render an "f, i" sequence
+ as <code class="literal">fi</code> or as "fi" does not

+<p>
+ When you add text to a HarfBuzz buffer, each code point must be
+ assigned a <span class="emphasis"><em>cluster value</em></span>.
+ </p>
+<p>
+ This cluster value is an arbitrary number; HarfBuzz uses it only
+ to distinguish between clusters. Many client programs will use
+ the index of each code point in the input text stream as the
+ cluster value. This is for the sake of convenience; the actual
+ value does not matter.
+ </p>
+<p>
+ Some of the shaping operations performed by HarfBuzz —
+ such as reordering, composition, decomposition, and substitution
+ — may alter the cluster values of some characters. The
+ final cluster values in the buffer at the end of the shaping
+ process will indicate to client programs which subsequences of
+ glyphs represent a cluster and, therefore, must not be
+ separated.
+ </p>
+<p>
+ In addition, client programs can query the final cluster values
+ to discern other potentially important information about the
+ glyphs in the output buffer (such as whether or not a ligature
+ was formed).
+ </p>
+<p>
+ For example, if the initial sequence of cluster values was:
+ </p>
+<pre class="programlisting">
+ 0,1,2,3,4
+ </pre>
+<p>
+ and the final sequence of cluster values is:
+ </p>
+<pre class="programlisting">
+ 0,0,3,3
+ </pre>
+<p>
+ then there are two clusters in the output buffer: the first
+ cluster includes the first two glyphs, and the second cluster
+ includes the third and fourth glyphs. It is also evident that a
+ ligature or conjunct has been formed, because there are fewer
+ glyphs in the output buffer (four) than there were code points
+ in the input buffer (five).

<title>Clusters</title>
- <para>
- In shaping text, a <emphasis>cluster</emphasis> is a sequence of
- code points that needs to be treated as a single, indivisible unit.
- </para>
- <para>
- When you add text to a HB buffer, each character is associated with
- a <emphasis>cluster value</emphasis>. This is an arbitrary number as
- far as HB is concerned.
- </para>
- <para>
- Most clients will use UTF-8, UTF-16, or UTF-32 indices, but the
- actual number does not matter. Moreover, it is not required for the
- cluster values to be monotonically increasing, but pretty much all
- of HB's tests are performed on monotonically increasing cluster
- numbers. Nevertheless, there is no such assumption in the code
- itself. With that in mind, let's examine what happens with cluster
- values during shaping under each cluster-level.
- </para>
- <para>
- HarfBuzz provides three <emphasis>levels</emphasis> of clustering
- support. Level 0 is the default behavior and reproduces the behavior
- of the old HarfBuzz library. Level 1 tweaks this behavior slightly
- to produce better results, so level 1 clustering is recommended for
- code that is not required to implement backward compatibility with
- the old HarfBuzz.
- </para>
- <para>
- Level 2 differs significantly in how it treats cluster values.
- Levels 0 and 1 both process ligatures and glyph decomposition by
- merging clusters; level 2 does not.
- </para>
- <para>
- The conceptual model for what the cluster values mean, in levels 0
- and 1, is this:
- </para>
- <itemizedlist spacing="compact">
- <listitem>
- <para>
- the sequence of cluster values will always remain monotone

- Assuming that initial cluster numbers were monotonically increasing
- and distinct, then all adjacent glyphs having the same cluster

- cluster number. This will become clearer with an example.
- </para>
-</sect1>
-<sect1 id="a-clustering-example-for-levels-0-and-1">
- <title>A clustering example for levels 0 and 1</title>
- <para>
- Let's say we start with the following character sequence and cluster
- values:
- </para>
- <programlisting>
- A,B,C,D,E
- 0,1,2,3,4
-</programlisting>
- <para>
- We then map the characters to glyphs. For simplicity, let's assume
- that each character maps to the corresponding, identical-looking
- glyph:
- </para>
- <programlisting>
- A,B,C,D,E
- 0,1,2,3,4
-</programlisting>
- <para>
- Now if, for example, <literal>B</literal> and <literal>C</literal>
- ligate, then the clusters to which they belong "merge".
- This merged cluster takes for its cluster number the minimum of all
- the cluster numbers of the clusters that went in. In this case, we
- get:
- </para>
- <programlisting>
- A,BC,D,E
- 0,1 ,3,4
-</programlisting>
- <para>
- Now let's assume that the <literal>BC</literal> glyph decomposes
- into three components, and <literal>D</literal> also decomposes into
- two. The components each inherit the cluster value of their parent:
- </para>
- <programlisting>
- A,BC0,BC1,BC2,D0,D1,E
- 0,1 ,1 ,1 ,3 ,3 ,4
-</programlisting>
- <para>
- Now if <literal>BC2</literal> and <literal>D0</literal> ligate, then
- their clusters (numbers 1 and 3) merge into
- <literal>min(1,3) = 1</literal>:
- </para>
- <programlisting>
- A,BC0,BC1,BC2D0,D1,E
- 0,1 ,1 ,1 ,1 ,4
-</programlisting>
- <para>
- At this point, cluster 1 means: the character sequence
- <literal>BCD</literal> is represented by glyphs
- <literal>BC0,BC1,BC2D0,D1</literal> and cannot be broken down any
- further.
- </para>
-</sect1>
-<sect1 id="reordering-in-levels-0-and-1">
- <title>Reordering in levels 0 and 1</title>
- <para>
- Another common operation in the more complex shapers is when things
- reorder. In those cases, to maintain monotone clusters, HB merges
- the clusters of everything in the reordering sequence. For example,
- let's again start with the character sequence:
- </para>
- <programlisting>
- A,B,C,D,E
- 0,1,2,3,4
-</programlisting>
- <para>
- If <literal>D</literal> is reordered before <literal>B</literal>,
- then the <literal>B</literal>, <literal>C</literal>, and
- <literal>D</literal> clusters merge, and we get:
- </para>
- <programlisting>
- A,D,B,C,E
- 0,1,1,1,4
-</programlisting>
- <para>
- This is clearly not ideal, but it is the only sensible way to
- maintain monotone indices and retain the true relationship between
- glyphs and characters.
- </para>
-</sect1>
-<sect1 id="the-distinction-between-levels-0-and-1">
- <title>The distinction between levels 0 and 1</title>
- <para>
- So, the above is pretty much what cluster levels 0 and 1 do. The
- only difference between the two is this: in level 0, at the very
- beginning of the shaping process, we also merge clusters between
- base characters and all Unicode marks (combining or not) following
- them. E.g.:
- </para>
- <programlisting>
- A,acute,B
- 0,1 ,2
-</programlisting>
- <para>
- will become:
- </para>
- <programlisting>
- A,acute,B
- 0,0 ,2
-</programlisting>
- <para>
- This is the default behavior. We do it because Windows did it and
- old HarfBuzz did it, so this remained the default. But this behavior
- makes it impossible to color diacritic marks differently from their
- base characters. That's why in level 1 we do not perform this
- initial merging step.
- </para>
- <para>
- For clients, level 0 is more convenient if they rely on HarfBuzz
- clusters for cursor positioning. But that's wrong anyway: cursor
- positions should be determined based on Unicode grapheme boundaries,
- NOT shaping clusters. As such, level 1 clusters are preferred.
- </para>
- <para>
- One last note about levels 0 and 1. We currently don't allow a
- <literal>MultipleSubst</literal> lookup to replace a glyph with zero
- glyphs (i.e., to delete a glyph). But in some other situations,
- glyphs can be deleted. In those cases, if the glyph being deleted is
- the last glyph of its cluster, we make sure to merge the cluster
- with a neighboring cluster.
- </para>
- <para>
- This is, primarily, to make sure that the starting cluster of the
- text always has the cluster index pointing to the start of the text
- for the run; more than one client currently relies on this
- guarantee.
- </para>
- <para>
- Incidentally, Apple's CoreText does something else to maintain the
- same promise: it inserts a glyph with id 65535 at the beginning of
- the glyph string if the glyph corresponding to the first character
- in the run was deleted. HarfBuzz might do something similar in the
- future.
- </para>
-</sect1>
-<sect1 id="level-2">
- <title>Level 2</title>
- <para>
- Level 2 is a different beast from levels 0 and 1. It is simple to
- describe, but hard to make sense of. It simply doesn't do any
- cluster merging whatsoever. When things ligate or otherwise multiple
- glyphs turn into one, the cluster value of the first glyph is
- retained.
- </para>
- <para>
- Here are a few examples of why processing cluster values produced at
- this level might be tricky:

+ <title>Clusters and shaping</title>
+ <para>
+ In text shaping, a <emphasis>cluster</emphasis> is a sequence of
+ characters that needs to be treated as a single, indivisible
+ unit. A single letter or symbol can be a cluster of its
+ own. Other clusters correspond to longer subsequences of the
+ input code points — such as a ligature or conjunct form
+ — and require the shaper to ensure that the cluster is not
+ broken during the shaping process.
+ </para>
+ <para>
+ A cluster is distinct from a <emphasis>grapheme</emphasis>,
+ which is the smallest unit of meaning in a writing system or
+ script.
+ </para>
+ <para>
+ The definitions of the two terms are similar. However, clusters
+ are only relevant for script shaping and glyph layout. In
+ contrast, graphemes are a property of the underlying script, and
+ are of interest when client programs implement orthographic
+ or linguistic functionality.
+ </para>
+ <para>
+ For example, two individual letters are often two separate
+ graphemes. When two letters form a ligature, however, they
+ combine into a single glyph. They are then part of the same
+ cluster and are treated as a unit by the shaping engine —
+ even though the two original, underlying letters remain separate
+ graphemes.
+ </para>
+ <para>
+ HarfBuzz is concerned with clusters, <emphasis>not</emphasis>
+ with graphemes — although client programs using HarfBuzz
+ may still care about graphemes for other reasons from time to time.
+ </para>
+ <para>
+ During the shaping process, there are several shaping operations
+ that may merge adjacent characters (for example, when two code
+ points form a ligature or a conjunct form and are replaced by a
+ single glyph) or split one character into several (for example,
+ when decomposing a code point through the
+ <literal>ccmp</literal> feature). Operations like these alter
+ clusters; HarfBuzz tracks the changes to ensure that no clusters
+ get lost or broken during shaping.
+ </para>
+ <para>
+ HarfBuzz records cluster information independently from how
+ shaping operations affect the individual glyphs returned in an
+ output buffer. Consequently, a client program using HarfBuzz can
+ utilize the cluster information to implement features such as:

+ <itemizedlist>

+ <para>
+ The functionality, guarantees, and benefits of level 0 and level
+ 1 behavior can be seen with some examples. First, let us examine
+ what happens with cluster values when shaping involves cluster
+ merging with ligatures and decomposition.
+ </para>
+
+ <para>
+ Let's say we start with the following character sequence (top row) and
+ initial cluster values (bottom row):
</para>
<programlisting>
- ABC,a,b,c
- 0 ,0,0,0
-</programlisting>
+ A,B,C,D,E
+ 0,1,2,3,4
+ </programlisting>
<para>
- level 1:
+ During shaping, HarfBuzz maps these characters to glyphs from
+ the font. For simplicity, let us assume that each character maps
+ to the corresponding, identical-looking glyph:
</para>
<programlisting>
- ABC,a,b,c
- 0 ,0,0,5
-</programlisting>
+ A,B,C,D,E
+ 0,1,2,3,4
+ </programlisting>
<para>
- level 2:
+ Now if, for example, <literal>B</literal> and <literal>C</literal>
+ form a ligature, then the clusters to which they belong
+ "merge". This merged cluster takes for its cluster
+ value the minimum of all the cluster values of the clusters that
+ went in to the ligature. In this case, we get:
</para>
<programlisting>
- ABC,a,b,c
- 0 ,1,3,5
-</programlisting>
+ A,BC,D,E
+ 0,1 ,3,4
+ </programlisting>
+ <para>
+ because 1 is the minimum of the set {1,2}, which were the
+ cluster values of <literal>B</literal> and
+ <literal>C</literal>.
+ </para>
+ <para>
+ Next, let us say that the <literal>BC</literal> ligature glyph
+ decomposes into three components, and <literal>D</literal> also
+ decomposes into two components. Whenever a cluster decomposes,
+ its components each inherit the cluster value of their parent:
+ </para>
+ <programlisting>
+ A,BC0,BC1,BC2,D0,D1,E
+ 0,1 ,1 ,1 ,3 ,3 ,4
+ </programlisting>
+ <para>
+ Next, if <literal>BC2</literal> and <literal>D0</literal> form a
+ ligature, then their clusters (cluster values 1 and 3) merge into
+ <literal>min(1,3) = 1</literal>:
+ </para>
+ <programlisting>
+ A,BC0,BC1,BC2D0,D1,E
+ 0,1 ,1 ,1 ,1 ,4
+ </programlisting>
+ <para>
+ Note that the entirety of cluster 3 merges into cluster 1, not
+ just the <literal>D0</literal> glyph. This reflects the fact
+ that the cluster <emphasis>must</emphasis> be treated as an
+ indivisible unit.
+ </para>
<para>
- Making sense of the last example is the hardest for a client,
- because there is nothing in the cluster values to suggest that
- <literal>B</literal> and <literal>C</literal> ligated with
- <literal>A</literal>.
+ At this point, cluster 1 means: the character sequence
+ <literal>BCD</literal> is represented by glyphs
+ <literal>BC0,BC1,BC2D0,D1</literal> and cannot be broken down any
+ further.

<para>
- Another tricky case is when things reorder. Under level 2:
+ Another common operation in the more complex shapers is glyph
+ reordering. In order to maintain a monotonic cluster sequence
+ when glyph reordering takes place, HarfBuzz merges the clusters
+ of everything in the reordering sequence.
+ </para>

+ For example, let us again start with the character sequence (top

- 0,1,2,3,4
-</programlisting>
+ A,B,C,D,E
+ 0,1,2,3,4
+ </programlisting>
<para>
- Now imagine <literal>D</literal> moves before
- <literal>B</literal>:
+ If <literal>D</literal> is reordered to the position immediately
+ before <literal>B</literal>, then HarfBuzz merges the
+ <literal>B</literal>, <literal>C</literal>, and
+ <literal>D</literal> clusters — all the clusters between
+ the final position of the reordered glyph and its original
+ position. This means that we get:
</para>
<programlisting>
- A,D,B,C,E
- 0,3,1,2,4
-</programlisting>
+ A,D,B,C,E
+ 0,1,1,1,4
+ </programlisting>
+ <para>
+ as the final cluster sequence.
+ </para>
+ <para>
+ Merging this many clusters is not ideal, but it is the only
+ sensible way for HarfBuzz to maintain the guarantee that the
+ sequence of cluster values remains monotonic and to retain the
+ true relationship between glyphs and characters.

+ <section id="the-distinction-between-levels-0-and-1">
+ <title>The distinction between levels 0 and 1</title>
+ <para>
+ The preceding examples demonstrate the main effects of using
+ cluster levels 0 and 1. The only difference between the two
+ levels is this: in level 0, at the very beginning of the shaping
+ process, HarfBuzz merges the cluster of each base character
+ with the clusters of all Unicode marks (combining or not) and
+ modifiers that follow it.
+ </para>
<para>
- Now, if <literal>D</literal> ligates with <literal>B</literal>, we
- get:
+ For example, let us start with the following character sequence
+ (top row) and accompanying initial cluster values (bottom row):
</para>
<programlisting>
- A,DB,C,E
- 0,3 ,2,4
-</programlisting>
+ A,acute,B
+ 0,1 ,2
+ </programlisting>
<para>
- In a different scenario, <literal>A</literal> and
- <literal>B</literal> could have ligated
- <emphasis>before</emphasis> <literal>D</literal> reordered; that
- would have resulted in:
+ The <literal>acute</literal> is a Unicode mark. If HarfBuzz is

+ <literal>A</literal> and <literal>acute</literal> clusters will
+ merge, and the result will become:
</para>
<programlisting>
- AB,D,C,E
- 0 ,3,2,4
-</programlisting>
+ A,acute,B
+ 0,0 ,2
+ </programlisting>
+ <para>
+ This merger is performed before any other script-shaping
+ steps.
+ </para>
+ <para>
+ This initial cluster merging is the default behavior of the
+ Windows shaping engine, and the old HarfBuzz codebase copied
+ that behavior to maintain compatibility. Consequently, it has
+ remained the default behavior in the new HarfBuzz codebase.
+ </para>
+ <para>
+ But this initial cluster-merging behavior makes it impossible
+ client programs to implement some features (such as to
+ color diacritic marks differently from their base
+ characters). That is why, in level 1, HarfBuzz does not perform
+ the initial merging step.
+ </para>
+ <para>
+ For client programs that rely on HarfBuzz cluster values to
+ perform cursor positioning, level 0 is more convenient. But
+ relying on cluster boundaries for cursor positioning is wrong: cursor
+ positions should be determined based on Unicode grapheme
+ boundaries, not on shaping-cluster boundaries. As such, using
+ level 1 clustering behavior is recommended.
+ </para>
<para>
- There's no way to differentiate between these two scenarios based
- on the cluster numbers alone.
+ One final facet of levels 0 and 1 is worth noting. HarfBuzz
+ currently does not allow any
+ <emphasis>multiple-substitution</emphasis> GSUB lookups to
+ replace a glyph with zero glyphs (in other words, to delete a
+ glyph).
</para>
<para>
- Another problem happens with ligatures under level 2 if the
- direction of the text is forced to opposite of its natural
- direction (e.g. left-to-right Arabic). But that's too much of a
- corner case to worry about.
+ But, in some other situations, glyphs can be deleted. In
+ those cases, if the glyph being deleted is the last glyph of its
+ cluster, HarfBuzz makes sure to merge the deleted glyph's
+ cluster with a neighboring cluster.
</para>
- </sect2>
-</sect1>
+ <para>
+ This is done primarily to make sure that the starting cluster of the
+ text always has the cluster index pointing to the start of the text
+ for the run; more than one client program currently relies on this
+ guarantee.
+ </para>
+ <para>
+ Incidentally, Apple's CoreText does something different to
+ maintain the same promise: it inserts a glyph with id 65535 at
+ the beginning of the glyph string if the glyph corresponding to
+ the first character in the run was deleted. HarfBuzz might do
+ something similar in the future.

+ The level 2 behavior is easy to describe, but it may be

+ performs no merging of clusters whatsoever.
+ </para>
+ <para>
+ This means that there is no initial base-and-mark merging step
+ (as is done in level 0), and it means that reordering moves and

+ <para>
+ When glyphs do form a ligature (or when some other feature

+ <title>An overview of the HarfBuzz shaping API</title>
+ <para>
+ The core of the HarfBuzz shaping API is the function
+ <function>hb_shape()</function>. This function takes a font, a
+ buffer containing a string of Unicode codepoints and
+ (optionally) a list of font features as its input. It replaces
+ the codepoints in the buffer with the corresponding glyphs from
+ the font, correctly ordered and positioned, and with any of the
+ optional font features applied.
+ </para>
+ <para>
+ In addition to holding the pre-shaping input (the Unicode
+ codepoints that comprise the input string) and the post-shaping
+ output (the glyphs and positions), a HarfBuzz buffer has several
+ properties that affect shaping. The most important are the
+ text-flow direction (e.g., left-to-right, right-to-left,
+ top-to-bottom, or bottom-to-top), the script tag, and the
+ language tag.
+ </para>
+
+ <para>
+ For input string buffers, flags are available to denote when the
+ buffer represents the beginning or end of a paragraph, to
+ indicate whether or not to visibly render Unicode <literal>Default
+ Ignorable</literal> codepoints, and to modify the cluster-merging
+ behavior for the buffer. For shaped output buffers, the
+ individual X and Y offsets and <literal>advances</literal>
+ (the logical dimensions) of each glyph are
+ accessible. HarfBuzz also flags glyphs as
+ <literal>UNSAFE_TO_BREAK</literal> if breaking the string at
+ that glyph (e.g., in a line-breaking or hyphenation process)
+ would require re-shaping the text.
+ </para>
+
+ <para>
+ HarfBuzz also provides methods to compare the contents of
+ buffers, join buffers, normalize buffer contents, and handle
+ invalid codepoints, as well as to determine the state of a
+ buffer (e.g., input codepoints or output glyphs). Buffer
+ lifecycles are managed and all buffers are reference-counted.
+ </para>
+
+ <para>
+ Although the default <function>hb_shape()</function> function is
+ sufficient for most use cases, a variant is also provide that
+ lets you specify which of HarfBuzz's shapers to use on a buffer.
+ </para>
+
+ <para>
+ HarfBuzz can read TrueType fonts, TrueType collections, OpenType
+ fonts, and OpenType collections. Functions are provided to query
+ font objects about metrics, Unicode coverage, available tables and
+ features, and variation selectors. Individual glyphs can also be
+ queried for metrics, variations, and glyph names. OpenType
+ variable fonts are supported, and HarfBuzz allows you to set
+ variation-axis coordinates on font objects.
+ </para>
+
+ <para>
+ HarfBuzz provides glue code to integrate with various other
+ libraries, including FreeType, GObject, and CoreText. Support
+ for integrating with Uniscribe and DirectWrite is experimental
+ at present.

- <title>What HarfBuzz doesn't do</title>
- <para>
- The code above will take a UTF8 string, shape it, and give you the
- information required to lay it out correctly on a single
- horizontal (or vertical) line using the font provided. That is the
- extent of HarfBuzz's responsibility.
- </para>
- <para>
- If you are implementing a text layout engine you may have other
- responsibilities, that HarfBuzz will not help you with:
- </para>
- <itemizedlist>
- <listitem>
- <para>
- HarfBuzz won't help you with bidirectionality. If you want to
- lay out text with mixed Hebrew and English, you will need to
- ensure that the buffer provided to HarfBuzz has those
- characters in the correct layout order. This will be different
- from the logical order in which the Unicode text is stored. In
- other words, the user will hit the keys in the following
- sequence:
- </para>
- <programlisting>
-A B C [space] ג ב א [space] D E F
- </programlisting>
- <para>
- but will expect to see in the output:
- </para>
- <programlisting>
-ABC אבג DEF
- </programlisting>
- <para>
- This reordering is called <emphasis>bidi processing</emphasis>
- ("bidi" is short for bidirectional), and there's an
- algorithm as an annex to the Unicode Standard which tells you how
- to reorder a string from logical order into presentation order.
- Before sending your string to HarfBuzz, you may need to apply the
- bidi algorithm to it. Libraries such as ICU and fribidi can do
- this for you.
- </para>
- </listitem>
- <listitem>
- <para>
- HarfBuzz won't help you with text that contains different font
- properties. For instance, if you have the string "a
- <emphasis>huge</emphasis> breakfast", and you expect
- "huge" to be italic, you will need to send three
- strings to HarfBuzz: <literal>a</literal>, in your Roman font;
- <literal>huge</literal> using your italic font; and
- <literal>breakfast</literal> using your Roman font again.
- Similarly if you change font, font size, script, language or
- direction within your string, you will need to shape each run
- independently and then output them independently. HarfBuzz
- expects to shape a run of characters sharing the same
- properties.
- </para>
- </listitem>
- <listitem>
- <para>
- HarfBuzz won't help you with line breaking, hyphenation or
- justification. As mentioned above, it lays out the string
- along a <emphasis>single line</emphasis> of, notionally,
- infinite length. If you want to find out where the potential
- word, sentence and line break points are in your text, you
- could use the ICU library's break iterator functions.
- </para>
- <para>
- HarfBuzz can tell you how wide a shaped piece of text is, which is
- useful input to a justification algorithm, but it knows nothing
- about paragraphs, lines or line lengths. Nor will it adjust the
- space between words to fit them proportionally into a line. If you
- want to layout text in paragraphs, you will probably want to send
- each word of your text to HarfBuzz to determine its shaped width
- after glyph substitutions, then work out how many words will fit
- on a line, and then finally output each word of the line separated
- by a space of the correct size to fully justify the paragraph.
- </para>
- </listitem>
- </itemizedlist>
- <para>
- As a layout engine implementor, HarfBuzz will help you with the
- interface between your text and your font, and that's something
- that you'll need - what you then do with the glyphs that your font
- returns is up to you. The example we saw above enough to get us
- started using HarfBuzz. Now we are going to use the remainder of
- HarfBuzz's API to refine that example and improve our text shaping
- capabilities.

+ <para>
+ Text shaping is the process of transforming a sequence of Unicode
+ codepoints that represent individual characters (letters,
+ diacritics, tone marks, numbers, symbols, etc.) into the
+ orthographically and linguistically correct two-dimensional layout
+ of glyph shapes taken from a specified font.
+ </para>
+ <para>
+ For some writing systems (or <emphasis>scripts</emphasis>) and
+ languages, the process is simple, requiring the shaper to do
+ little more than advance the horizontal position forward by the
+ correct amount for each successive glyph.
+ </para>
+ <para>
+ But, for <emphasis>complex scripts</emphasis>, any combination of
+ several shaping operations may be required, and the rules for how
+ and when they are applied vary from script to script. HarfBuzz and
+ other shaping engines implement these rules.
+ </para>
+ <para>
+ The exact rules and necessary operations for a particular script
+ constitute a shaping <emphasis>model</emphasis>. OpenType
+ specifies a set of shaping models that covers all of
+ Unicode. Other shaping models are available, however, including
+ Graphite and Apple Advanced Typography (AAT).

+ <title>Complex scripts</title>
+ <para>
+ In text-shaping terminology, scripts are generally classified as
+ either <emphasis>complex</emphasis> or <emphasis>non-complex</emphasis>.
+ </para>
+ <para>
+ Complex scripts are those for which transforming the input
+ sequence into the final layout requires some combination of
+ operations—such as context-dependent substitutions,
+ context-dependent mark positioning, glyph-to-glyph joining,
+ glyph reordering, or glyph stacking.
+ </para>
+ <para>
+ In some complex scripts, the shaping rules require that a text
+ run be divided into syllables before the operations can be
+ applied. Other complex scripts may apply shaping operations over
+ entire words or over the entire text run, with no subdivision
+ required.
+ </para>
+ <para>
+ Non-complex scripts, by definition, do not require these
+ operations. However, correctly shaping a text run in a
+ non-complex script may still involve Unicode normalization,
+ ligature substitutions, mark positioning, kerning, and applying
+ other font features. The key difference is that a text run in a
+ non-complex script can be processed sequentially and in the same
+ order as the input sequence of Unicode codepoints, without
+ requiring an analysis stage.

+ Every codepoint in the Unicode Character Database (UCD) is

+ "Letter, modifier" (<literal>Lm</literal>).
+ </para>
+ <para>
+ Shaping models are concerned primarily with Letter and Mark

+ (<literal>Mn</literal>), spacing combining
+ (<literal>Mc</literal>), or enclosing (<literal>Me</literal>).
+ </para>
+ <para>
+ In addition to the UGC property, codepoints in the Indic and

+ properties that provide more detailed information needed for

+ <para>
+ The UISC property sub-categorizes Letters and Marks according to

+ between consonant letters, vowel letters, and vowel marks. The
+ UIPC property sub-categorizes Mark codepoints by the relative visual
+ position that they occupy (above, below, right, left, or in
+ multiple positions).
+ </para>
+ <para>
+ Some complex scripts require that the text run be split into
+ syllables. What constitutes a valid syllable in these

+ HarfBuzz can read and understand TrueType fonts (.ttf), TrueType

+ <title>What HarfBuzz doesn't do</title>
+ <para>
+ HarfBuzz will take a Unicode string, shape it, and give you the
+ information required to lay it out correctly on a single
+ horizontal (or vertical) line using the font provided. That is the
+ extent of HarfBuzz's responsibility.
+ </para>
+ <para>
+ It is important to note that if you are implementing a complete
+ text-layout engine you may have other responsibilities that
+ HarfBuzz will <emphasis>not</emphasis> help you with. For example:
+ </para>
+ <itemizedlist>
+ <listitem>
+ <para>
+ HarfBuzz won't help you with bidirectionality. If you want to
+ lay out text that includes a mix of Hebrew and English, you
+ will need to ensure that each buffer provided to HarfBuzz
+ has all of its characters in the same order and that the
+ directionality of the buffer is set correctly. This may mean
+ segmenting the text before it is placed into HarfBuzz buffers. In
+ other words, the user will hit the keys in the following
+ sequence:
+ </para>
+ <programlisting>
+ A B C [space] ג ב א [space] D E F
+ </programlisting>
+ <para>
+ but will expect to see in the output:
+ </para>
+ <programlisting>
+ ABC אבג DEF
+ </programlisting>
+ <para>
+ This reordering is called <emphasis>bidi processing</emphasis>
+ ("bidi" is short for bidirectional), and there's an
+ algorithm as an annex to the Unicode Standard which tells you how
+ to process a string of mixed directionality.
+ Before sending your string to HarfBuzz, you may need to apply the
+ bidi algorithm to it. Libraries such as <ulink
+ url="http://icu-project.org/">ICU</ulink> and <ulink
+ url="http://fribidi.org/">fribidi</ulink> can do this for you.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ HarfBuzz won't help you with text that contains different font
+ properties. For instance, if you have the string "a
+ <emphasis>huge</emphasis> breakfast", and you expect
+ "huge" to be italic, then you will need to send three
+ strings to HarfBuzz: <literal>a</literal>, in your Roman font;
+ <literal>huge</literal> using your italic font; and
+ <literal>breakfast</literal> using your Roman font again.
+ </para>
+ <para>
+ Similarly, if you change the font, font size, script,
+ language, or direction within your string, then you will
+ need to shape each run independently and output them
+ independently. HarfBuzz expects to shape a run of characters
+ that all share the same properties.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ HarfBuzz won't help you with line breaking, hyphenation, or
+ justification. As mentioned above, HarfBuzz lays out the string
+ along a <emphasis>single line</emphasis> of, notionally,
+ infinite length. If you want to find out where the potential
+ word, sentence and line break points are in your text, you
+ could use the ICU library's break iterator functions.
+ </para>
+ <para>
+ HarfBuzz can tell you how wide a shaped piece of text is, which is
+ useful input to a justification algorithm, but it knows nothing
+ about paragraphs, lines or line lengths. Nor will it adjust the
+ space between words to fit them proportionally into a line.
</para>

<para>
- If this is something that you need to do, then you need a text
- shaping engine: you could use Uniscribe if you are using Windows;
- you could use CoreText on OS X; or you could use HarfBuzz. In the
- rest of this manual, we are going to assume that you are the
- implementor of a text layout engine.
+ As a layout-engine implementor, HarfBuzz will help you with the
+ interface between your text and your font, and that's something
+ that you'll need—what you then do with the glyphs that your font
+ returns is up to you.

*
* In general, this file does a fine job of what it's supposed to do.
* There are, however, things that need more work:
*
- * - I remember seeing FT_Get_Advance() without the NO_HINTING flag to be buggy.
- * Have not investigated.
- *
* - FreeType works in 26.6 mode. Clients can decide to use that mode, and everything
* would work fine. However, we also abuse this API for performing in font-space,
* but don't pass the correct flags to FreeType. We just abuse the no-hinting mode
* for that, such that no rounding etc happens. As such, we don't set ppem, and
* pass NO_HINTING as load_flags. Would be much better to use NO_SCALE, and scale
- * ourselves, like we do in uniscribe, etc.
+ * ourselves.
*
* - We don't handle / allow for emboldening / obliqueing.
*
* - In the future, we should add constructors to create fonts in font space?
- *
- * - FT_Load_Glyph() is extremely costly. Do something about it?

+/*
+ * Sanitize
+ *
+ *
+ * === Introduction ===
+ *
+ * The sanitize machinery is at the core of our zero-cost font loading. We
+ * mmap() font file into memory and create a blob out of it. Font subtables
+ * are returned as a readonly sub-blob of the main font blob. These table
+ * blobs are then sanitized before use, to ensure invalid memory access does
+ * not happen. The toplevel sanitize API use is like, eg. to load the 'head'
+ * table:
+ *
+ * hb_blob_t *head_blob = hb_sanitize_context_t ().reference_table<OT::head> (face);
+ *
+ * The blob then can be converted to a head table struct with:
+ *
+ * const head *head_table = head_blob->as<head> ();
+ *
+ * What the reference_table does is, to call hb_face_reference_table() to load
+ * the table blob, sanitize it and return either the sanitized blob, or empty
+ * blob if sanitization failed. The blob->as() function returns the null
+ * object of its template type argument if the blob is empty. Otherwise, it
+ * just casts the blob contents to the desired type.
+ *
+ * Sanitizing a blob of data with a type T works as follows (with minor
+ * simplification):
+ *
+ * - Cast blob content to T*, call sanitize() method of it,
+ * - If sanitize succeeded, return blob.
+ * - Otherwise, if blob is not writable, try making it writable,
+ * or copy if cannot be made writable in-place,
+ * - Call sanitize() again. Return blob if sanitize succeeded.
+ * - Return empty blob otherwise.
+ *
+ *
+ * === The sanitize() contract ===
+ *
+ * The sanitize() method of each object type shall return true if it's safe to
+ * call other methods of the object, and false otherwise.
+ *
+ * Note that what sanitize() checks for might align with what the specification
+ * describes as valid table data, but does not have to be. In particular, we
+ * do NOT want to be pedantic and concern ourselves with validity checks that
+ * are irrelevant to our use of the table. On the contrary, we want to be
+ * lenient with error handling and accept invalid data to the extent that it
+ * does not impose extra burden on us.
+ *
+ * Based on the sanitize contract, one can see that what we check for depends
+ * on how we use the data in other table methods. Ie. if other table methods
+ * assume that offsets do NOT point out of the table data block, then that's
+ * something sanitize() must check for (GSUB/GPOS/GDEF/etc work this way). On
+ * the other hand, if other methods do such checks themselves, then sanitize()
+ * does not have to bother with them (glyf/local work this way). The choice
+ * depends on the table structure and sanitize() performance. For example, to
+ * check glyf/loca offsets in sanitize() would cost O(num-glyphs). We try hard
+ * to avoid such costs during font loading. By postponing such checks to the
+ * actual glyph loading, we reduce the sanitize cost to O(1) and total runtime
+ * cost to O(used-glyphs). As such, this is preferred.
+ *
+ * The same argument can be made re GSUB/GPOS/GDEF, but there, the table
+ * structure is so complicated that by checking all offsets at sanitize() time,
+ * we make the code much simpler in other methods, as offsets and referenced
+ * objects do not need to be validated at each use site.
+ */
+
+/* This limits sanitizing time on really broken fonts. */

- * Yes, it is correct that a new version of the AFDKO (version 2.0) will be
- * coming out soon, and that the makeotf program will build a font with a
- * 'size' feature that is correct by the specification.
- *
- * The specification for this feature tag is in the "OpenType Layout Tag
- * Registry". You can see a copy of this at:
- * https://docs.microsoft.com/en-us/typography/opentype/spec/features_pt#tag-size
- *
- * Here is one set of rules to determine if the 'size' feature is built
- * correctly, or as by the older versions of MakeOTF. You may be able to do
- * better.
- *
- * Assume that the offset to the size feature is according to specification,
- * and make the following value checks. If it fails, assume the size
- * feature is calculated as versions of MakeOTF before the AFDKO 2.0 built it.
- * If this fails, reject the 'size' feature. The older makeOTF's calculated the
- * offset from the beginning of the FeatureList table, rather than from the
- * beginning of the 'size' Feature table.
- *
- * If "design size" == 0:
- * fails check
- *
- * Else if ("subfamily identifier" == 0 and
- * "range start" == 0 and
- * "range end" == 0 and
- * "range start" == 0 and
- * "menu name ID" == 0)
- * passes check: this is the format used when there is a design size
- * specified, but there is no recommended size range.
- *
- * Else if ("design size" < "range start" or
- * "design size" > "range end" or
- * "range end" <= "range start" or
- * "menu name ID" < 256 or
- * "menu name ID" > 32767 or
- * menu name ID is not a name ID which is actually in the name table)
- * fails test

+ * coming out soon, and that the makeotf program will build a font with a
+ * 'size' feature that is correct by the specification.
+ *
+ * The specification for this feature tag is in the "OpenType Layout Tag
+ * Registry". You can see a copy of this at:
+ * https://docs.microsoft.com/en-us/typography/opentype/spec/features_pt#tag-size
+ *
+ * Here is one set of rules to determine if the 'size' feature is built
+ * correctly, or as by the older versions of MakeOTF. You may be able to do
+ * better.
+ *
+ * Assume that the offset to the size feature is according to specification,
+ * and make the following value checks. If it fails, assume the size
+ * feature is calculated as versions of MakeOTF before the AFDKO 2.0 built it.
+ * If this fails, reject the 'size' feature. The older makeOTF's calculated the
+ * offset from the beginning of the FeatureList table, rather than from the
+ * beginning of the 'size' Feature table.
+ *
+ * If "design size" == 0:
+ * fails check
+ *
+ * Else if ("subfamily identifier" == 0 and
+ * "range start" == 0 and
+ * "range end" == 0 and
+ * "range start" == 0 and
+ * "menu name ID" == 0)
+ * passes check: this is the format used when there is a design size
+ * specified, but there is no recommended size range.
+ *
+ * Else if ("design size" < "range start" or
+ * "design size" > "range end" or
+ * "range end" <= "range start" or
+ * "menu name ID" < 256 or
+ * "menu name ID" > 32767 or

- * This is perhaps the trickiest part of OpenType... Remarks:

- *
- * - Ligatures cannot be formed across glyphs attached to different components
- * of previous ligatures. Eg. the sequence is LAM,SHADDA,LAM,FATHA,HEH, and
- * LAM,LAM,HEH form a ligature, leaving SHADDA,FATHA next to eachother.
- * However, it would be wrong to ligate that SHADDA,FATHA sequence.
- * There are a couple of exceptions to this:
- *
- * o If a ligature tries ligating with marks that belong to it itself, go ahead,
- * assuming that the font designer knows what they are doing (otherwise it can
- * break Indic stuff when a matra wants to ligate with a conjunct,
- *
- * o If two marks want to ligate and they belong to different components of the
- * same ligature glyph, and said ligature glyph is to be ignored according to
- * mark-filtering rules, then allow.
