8 This file describes recent user-visible changes in groff. Bug fixes are not
9 described. There are more details in the man and info pages.
18 o The character `#' can now be used as an eqn delimiter within tables.
28 has been added to reactivate delimiters which have been disabled with
35 (There was no release 1.22.)
40 o A new option `-j' has been added to call the `chem' preprocessor.
45 o Improved line numbering support.
50 o Support for the `refer' preprocessor has been added to the -mm macro
53 o In -me, the `TH' macro was changed for compatibility with line number
56 `bl' now works inside of blocks.
58 The behaviour of centered blocks has been improved.
60 Line numbering support has been improved.
62 o The -mom macro package has reached version 2.0, focusing on PDF output
63 with gropdf (using the new `pdfmom' wrapper script). See the file
64 `version-2.html' of the -mom documentation for a list of the many changes.
66 o Some generic Unicode fallback characters (mainly Roman numerals) have been
72 o A new driver for generating PDF output directly, contributed by Deri James
73 <deri@chuzzlewit.myzen.co.uk>. Note that this driver is written in Perl,
74 thus you need a working Perl installation to run this output device.
79 o A new wrapper around groff that facilitates the production of PDF
80 documents from files formatted with the -mom macros.
89 o The new `lsm' request specifies a macro to be invoked when leading spaces
90 in an input line are encountered (which are removed then). Number
91 registers `lsn' and `lss' hold the number of removed leading spaces and
92 the corresponding horizontal space, respectively.
94 o There is a new warning category `file', enabled by default. The `mso'
95 request emits warnings in this category when the requested macro file does
98 o The new `class' request assigns a short name to a set of characters
99 which can be referred to in the `cflags' request. This is especially
100 useful to control line-breaking and hyphenation rules in CJK languages.
102 o Three new values for the `cflags' request have been added, which are
103 needed for proper CJK support.
105 128 prohibit before but allow break after character
106 256 prohibit after but allow break before character
107 512 allow break before and after character
112 o A new global option `nowarn' suppresses warnings if tables are longer than
113 the current line width.
118 o New option `-o' to specify the name of the output file.
123 o A new macro `%U' has been added to the mdoc package to indicate a URL
124 reference within an .Rs/.Re environment.
126 o Rudimentary support for the Japanese script has been added, most suitable
127 for man page handling as output by grotty. The file `ja.tmac' contains
128 the necessary setup to allow line breaks before and after CJK characters
129 (with proper exceptions). Note, however, that no inter-character spacing
130 is implemented yet -- this usually causes many warnings about bad line
137 A packaging error made it necessary to publish this release. No
138 user-visible changes.
147 o XHTML support has been added to grohtml and can be specified by
148 -Txhtml. This option also utilizes the MathML capability of
149 eqn and combines the outputs of both in the final XHTML file.
150 Users can also specify the `-P-V' option together with `-Txhtml'
151 in groff. This has the effect of creating an XHTML validator
152 button at the bottom of each page.
154 o Some options have been added to control a new preprocessor,
155 `preconv' (see below): `-k' activates it, `-K' sets the input
156 encoding, and `-D' sets the default encoding.
158 o A new environment variable `GROFF_ENCODING' sets the encoding
159 of input files; it implies command option `-k'.
164 o Two new requests `device' and `devicem' have been added which are
165 equivalents to the \X and \Y escapes, respectively.
167 o A new read-only number register `.br' is available which is set to 1
168 if a macro is called as .foo and to 0 if called as 'foo. This allows to
169 reliably modify requests.
174 . ie \\n[.br] .bp@orig
179 o A new request `fzoom' has been added to adjust the optical size of a
180 font in relation to the others. The zoom factor is given in integer
181 multiples of 1/1000th. In the following example, the CR font is
182 magnified by 10% (the zoom factor is 1.1).
187 Palatino and \f[CR]Courier\f[]
189 The new number register `.zoom' holds the zoom value of the current font,
190 in multiples of 1/1000th.
192 o The `cflags' request has been extended with a new flag value 64, to be
193 used in combination with values 2 (break before character) and 4 (break
194 after character). If set, the hyphenation codes of the surrounding
195 characters are ignored.
197 o A new debugging request, `pev', has been added to print all of the current
198 known environments to stderr. It first prints the state of the current
199 environment, then iterates through all of the known environments, printing
200 each except the one that is current.
202 o A new escape `\$^' has been added. It represents the parameters of a
203 macro as if they were an argument to the `ds' request. This is used by
206 o A new read-only number register `.O' is available which returns the
207 current suppression level as set by the `\O' escape.
209 o The space width emitted by the `\|' and `\^' escape sequences can be
210 controlled on a per-font basis. If there is a glyph named `\|' or `\^',
211 respectively (note the leading backslash), defined in the current font
212 file, use this glyph's width instead of the default value.
214 This behaviour is not new, but hasn't been documented before.
219 o Two new command line options `-w' and `-W' are accepted and passed to
220 groff to enable and disable warning messages, respectively.
225 o This is a new preprocessor to convert various input encodings to something
226 groff understands (this is, ASCII and \[uXXXX] entities, with `XXXX' a
227 hexadecimal number with 4 to 6 digits, representing a Unicode input code).
228 Normally, preconv should be invoked with options `-k' and `-K' of groff.
229 See the preconv man page for details.
234 o int(x) now really behaves as documented: It truncates the non-integer part
235 of x, this is, it rounds towards zero and not towards the next integer
236 less than or equal to x.
238 o Pic now supports up to 32 macro arguments (and up to 16 on EBCDIC
241 o Heinz-Jürgen Örtel contributed code for two new keywords, `xslanted' and
242 `yslanted', which can change the shape of boxes into arbitrary
248 o Latest versions of DWB tbl introduced an `x' column specifier for a single
249 column expanded to the line width. GNU tbl has now been extended to
250 support even multiple `x' specifiers within a table.
252 o To avoid collision with the new `x' specifier, a block formatting macro
253 must now be selected with specifier letter `m'.
258 o Eric S. Raymond has added a new device type to eqn, MathML. When
259 -TMathML is enabled, eqn now emits MathML formula markup rather than
260 groff commands. The new groff -Txhtml device uses this.
265 o The preprocessor `chem' was added. `chem' is a roff language to generate
266 chemical structure diagrams. It generates `pic' output.
271 o The PS font definition files have been regenerated with newer AFM versions
272 from Adobe's 35 core fonts as present in most Level 2 PS printers. The
273 changes are minor (most notably, the addition of the `Euro' glyph and an
274 extended set of kerning values).
276 For backwards compatibility, the old set of font definition files is still
277 available; for details please read the man page of grops.
282 o \D'p...' is now supported if the polygon consists entirely of horizontal
288 o XHTML support has been added.
290 o New command line option `-V' (to be used in XHTML mode) to produce an
291 XHTML validator button.
293 o New command line option `-y' to produce a right-justified groff signature
294 at the end of the document (in combination with option `-V').
299 o Support for keyboard navigation has been improved.
301 o Similar to other X11 applications, there are now two resource files,
302 `GXditview' and `GXditview-color'.
307 o `groffer' version 1.* exists now in a shell and a Perl version.
312 o New option `-c' to output more font information as comments.
314 o New option `-k' to suppress output of kerning data.
316 o New option `-f NAME' to set the internal name of the groff font.
321 o Joachim Walsdorff contributed the `hdtbl' package for the generation of
322 tables, using a syntax very similar to the HTML table model. For
323 example, a table with two cells and two rows looks like this:
330 Here the same table using a more expanded syntax:
341 Tables can be nested; `hdtbl' works without a preprocessor so that the
342 full capability of groff's macro engine is available.
344 This package currently works with `-Tps' only.
346 o -mandoc now supports multiple man pages (in either man or mdoc format).
348 o Fabrice Ménard contributed locales support. In particular, it is now
349 possible to get French localization of the main macro packages (-ms, -mm,
350 -me, and -mom, but not -man and -mdoc which are localized differently) by
351 appending `-mfr' to the list of macro packages. Example:
353 groff -ms -mfr foo > foo.ps
355 Note that latin-9 input encoding is used for French (to support the `oe'
358 o Swedish macro localization (with `-msv') has been added.
360 o German macro localization (with `-mde' and `-mden' for traditional and
361 new orthography, respectively) has been added.
363 o Czech macro localization (with `-mcs') has been added.
365 Note that latin-2 input encoding is used for Czech.
367 o A new macro `Dx' has been added to the mdoc package which identifies the
370 o If mdoc is used to print multiple man pages (together with the -rcR=0
371 command line option), each man page now starts a new page.
373 o -mtrace has been considerably improved, now showing number and string
374 register assignments, among other things. See the groff_trace man page
377 o The PSPIC macro now works with all devices (producing a hollow
378 rectangle on devices which don't support inclusion of PS images) and
379 is loaded in troffrc at start-up.
381 o A new auxiliary macro package `62bit' has been added which provides some
382 macros for adding, multiplying, and dividing signed 62bit integers (mainly
383 to handle normal groff number operations without risking overflow errors).
385 o For -ms, Eric S. Raymond contributed support for ancient Bell Labs
386 localisms `.SC', `.UC', `.P1', and `.P2'. The latter three are enabled
387 only after .SC is called.
389 o A new string, `SN-STYLE', has been added to the ms macros, controlling
390 the formatting of section numbers in headings defined by `.NH'.
392 o The new macro package `ptx' provides a template definition for the `.xx'
393 macro as needed by GNU ptx (for creating permuted indices).
402 o Analogously to the .ft and \f pair, two new requests `gcolor' and
403 `fcolor' (which pair with \m and \M, respectively) have been added to
404 set the glyph and background colours.
406 o A new read-only, string-valued register `.sty' returns the name of the
409 o Two new conditional operators `F <name>' and `S <name>' have been added.
410 `F' is true if a font <name> exists. `S' is true if a style <name> has
413 o Cyrillic characters have been added to the `utf8' and `html' output
419 o The `by' argument in a `for' loop can now be negative if it is additive.
420 For the multiplicative case, it must be greater than zero.
425 o The following keywords aren't new but haven't been documented previously:
427 undef NAME (to undefine a macro)
428 copy "FILE" (a synonym for `include')
429 space n (to modify the vertical spacing before and after
432 o The following macros aren't new but haven't been documented previously:
434 Alpha, ..., Omega (the same as `ALPHA', ..., `OMEGA')
435 ldots (three dots on the base line)
436 dollar (a dollar glyph)
438 o The following keywords have been extended. Again, this isn't new but
439 hasn't been documented previously:
448 cpile n { ... } (set vertical spacing between rows to N)
453 o This device driver has been raised to beta stage; its set of tags should
456 o New command line option `-s' to set the base point size.
458 o New command line option `-S' to set the split level while generating
464 o Experimental support for zero-width and double-width characters.
469 o On platforms which have the X Window System this program is now built and
470 installed automatically.
475 o This program to create font definition files for xditview isn't new but
476 hasn't been installed previously.
481 o A security problem (reported as CAN-2004-0969) has been fixed.
486 o A new script contributed by Mike Bianchi. It compares two groff, nroff,
487 or troff documents and creates an output with added margin characters
488 (using `.mc') to indicate the differences.
493 o A new wrapper script contributed by Keith Marshall to easily create PDF
494 documents with groff.
501 . Support for fractional point sizes: A value for the `PS', `VS', `FPS',
502 and `VPS' register larger than or equal to 1000 is always divided by
503 1000. For example, `.nr PS 10250' sets the document's font size to
506 . The `Ds' and `De' macros provided in ms since groff version 1.19 have
507 been removed; the equivalent `DS' and `DE' macros should be used
508 instead. X11 documents which actually use `Ds' and `De' always load a
509 specific macro file from the X11 distribution (`macros.t') which
510 provides proper definitions for the two macros.
512 . The following registers have been added for improving layout control:
515 Defines number of lines following `LP', `PP', `QP', `IP' or `XP' which
516 must be kept together, before any automatic page break.
519 Sets number of lines of following paragraph which must be kept with a
520 heading, defined by `NH' or `SH', before any automatic page break.
523 Sets the first level of heading (set with `NH') which keeps the
524 same point size as body text.
527 Sets the point size increment for each level of heading (set with
528 `NH'), below the threshold level set by `GROWPS'; e.g., if
529 \n[PS] = 10, \n[GROWPS] = 3 and \n[PSINCR] = 2.0p, then `.NH 1'
530 produces 14pt headings, `.NH 2' produces 12pt, and all other
531 levels remain at 10pt (because \n[PS] = 10).
533 . The `SH' macro now accepts a numeric argument, to make heading size
534 match that of `NH' with same argument value when the `GROWPS'/`PSINCR'
537 Please refer to the documentation of the ms package for other, minor
542 The section type set with the `++' request is available in the `_M'
543 register. This isn't new but hasn't been documented before.
547 The `HR' macro no longer causes an empty line for non-HTML devices.
549 A new macro `HEAD' has been added to directly add data to the
550 <head>...</head> block.
552 New macros `OLS' and `OLE' to start and end an ordered list.
554 New macros `DLS' and `DLE' to start and end a definition list.
559 o A new macro package contributed by Keith Marshall which implements PDF
560 marks. This is in alpha stage currently.
565 o Two new keywords to the DESC file have been added which are needed for
566 grohtml: `image_generator' and `unscaled_charwidths'. The former gives
567 the name of the program which creates PNG images, and the latter makes
568 troff always use unscaled character widths.
577 o The argument of the command line option `-I' is now also passed to troff
578 and grops, specifying a directory to search for files on the command line,
579 files named in `so' and `psbb' requests, and files named in \X'ps: file'
580 and \X'ps: import' escapes.
582 o If option `-V' is used more than once, the commands are both printed
583 on standard error and run.
588 o Two new read-only, string-valued registers `.m' and `.M' return the
589 name of the current drawing and background color, respectively.
591 o New read-only register `.U' which is set to 1 if in safer mode and set
592 to 0 if in unsafe mode.
594 o An input encoding file for latin-5 (a.k.a. ISO 8859-9) has been added.
597 groff -Tdvi -mlatin5 my_file > my_file.dvi
599 Note that some output devices don't support all glyphs of this encoding.
601 o If the `return' request is called with an argument, it exits twice,
602 namely the current macro and the macro one level higher. This is
603 used to define a wrapper macro for `return' in trace.tmac.
605 o For completeness, two new requests have been added: `dei1' and `ami1'.
606 They are equivalent to `dei' and `ami', respectively, but the macros
607 are executed with compatibility mode off (similar to `de1' and `am1').
609 o New command line option `-I' to specify a directory for files (both
610 those on the command line and those named in `psbb' requests). This is
611 also handled by the groff wrapper program.
613 o Since version 1.19 you can say `.vs 0'. Older versions emit a warning
614 and convert this to `.vs \n[.V]'.
616 This hasn't been documented properly. Note that `.vs 0' isn't saved in a
617 diversion since it doesn't result in vertical motion.
622 o Dashed and dotted ellipses have been implemented.
627 o New specifier `x' to make tbl call a user-defined macro on a table
628 cell. Patch by Heinz-Jürgen Oertel <hj.oertel@surfeu.de>.
633 o A new script contributed by Eric S. Raymond <esr@thyrsus.com>. It
634 converts a grap diagram into a cropped image. Since it uses gs and the
635 PNM library, virtually all graphics formats are available for output.
636 [Note that the grap program itself isn't part of the groff package;
637 see the file MORE.STUFF how to obtain grap.]
642 o New option `-j' to emit output split into multiple files.
647 o New command line option `-I' to specify a directory to search for files
648 on the command line and files named in \X'ps: import' and \X'ps: file'
649 escapes. This is also handled by the groff wrapper program.
651 o The default value for the `broken' keyword in the DESC file is now 0.
656 o A new man page `lj4_font(5)' documents how fonts are accessed with
659 o The built-in fonts for LJ4 and newer PCL 5 devices have been completely
660 revised, mainly to access as much glyphs as possible. The provided
661 metric files should be compatible with recent PCL 5 printers also.
662 Additionally, font description files have been added for the Arial and
663 Times New Roman family, the MS symbol, and Wingdings fonts.
668 o New option `-x' to prevent use of built-in Adobe Glyph List.
673 o Completely revised to handle HP TrueType metric files also. See the
674 hpftodit manual page for more details.
679 o This version is a rewrite of groffer in many parts, but it is kept in
680 the old single script style.
682 New options: --text, --mode text, --tty-viewer, --X, --mode X,
683 --X-viewer, --html, --mode html, --html-view, --apropos-data,
684 --apropos-devel, --apropos-progs.
686 New documentation file: README_SH.
688 Enhancement of the configuration files and the `apropos' handling.
693 o www.tmac: New macro `JOBNAME' to split output into multiple files.
695 o In mdoc, multiple calls to `.Lb' are now supported in the LIBRARY
705 o Input encoding files for latin-9 (a.k.a. latin-0 and ISO 8859-15) and
706 latin-2 (ISO 8859-2) have been added. Example use:
708 groff -Tdvi -mlatin9 my_file > my_file.dvi
710 You still need proper fonts with the necessary glyphs. Out of the box,
711 the groff package supports latin-9 only for -Tps, -Tdvi, and -Tutf8,
712 and latin-2 only for -Tdvi and -Tutf8.
714 o Composite glyphs are now supported. To do this, a subset of the Adobe
715 Glyph List (AGL) Algorithm as described in
717 http://partners.adobe.com/public/developer/opentype/index_glyph.html
719 is used to construct glyph names based on Unicode character codes. The
720 existing groff glyph names are frozen; no glyph names which can't be
721 constructed algorithmically will be added in the future.
723 The \[...] escape sequence has been extended to specify multiple glyph
728 this accesses a glyph with the name `u0041_0328'.
730 Some groff glyphs which are useful as composites map to `wrong' Unicode
731 code points. For example, `ho' maps to U+02DB which is a spacing
732 ogonek, whereas a non-spacing ogonek U+0328 is needed for composite
733 glyphs. The new request
737 changes the mapping while a composite glyph name is constructed.
738 To make \[A ho] yield the expected result,
742 is needed. [The new file `composite.tmac' loaded at start-up already
743 contains proper calls to `.composite'.]
745 Please refer to the info pages of groff and to the groff_char man page
748 o A new request `fschar' has been added to define font-specific fallback
749 characters. They are searched after the list of fonts declared with the
750 `fspecial' request but before the list of fonts declared with `special'.
752 o Fallback characters defined with `fschar' can be removed with the
753 new `rfschar' request.
755 o A new request `schar' has been added to define global fallback
756 characters. They are searched after the list of fonts declared with the
757 `special' request but before the already mounted special fonts.
759 o In groff versions 1.18 and 1.18.1, \D'f ...' didn't move the current
760 point horizontally. Despite of being silly, this change has been
761 reverted for backwards compatibility. Consequently, the intermediate
762 output command `Df' also moves the position horizontally again.
764 \D'f ...' is deprecated since it depends on the horizontal resolution of
765 the output device (given with the `hor' parameter in the DESC file).
766 Use the new \D'Fg ...' escape instead.
768 o For orthogonality, new \D subcommands to change the fill color are
775 \D'Fd' (default color)
777 The arguments are the same as with the `defcolor' request. The current
778 position is *not* changed.
780 o The values set with \H and \S are now available in number registers
781 \n[.height] and \n[.slant], respectively.
783 o The `.pe' number register isn't new but hasn't been documented before.
784 It is set to 1 during a page ejection caused by the `bp' request.
786 o The new glyph symbol `tno' is a textual variant of `no'.
788 o The new glyph symbol `+e' represents U+03F5, GREEK LUNATE EPSILON SYMBOL.
789 (Well, it is not really new since it has been previously supported by
790 grolj4.) The mapping for both the dvi and lj4 symbol font has been
791 changed accordingly so that Greek small letter epsilon, `*e', has the
792 same glyph shape as with other devices.
797 o The font `freeeuro.pfa' has been added to provide various default glyph
798 shapes for `eu' and `Eu'.
800 o It is now possible to access all glyphs in a Type 1 font, not only 256
801 (provided the font file created by afmtodit has proper entries). grops
802 constructs additional encoding vectors on the fly if necessary.
804 o The paper size is now emitted via the %%DocumentMedia and PageSize
805 mechanisms so that it is no longer required to tell `gv' or `ps2pdf'
806 about the paper size. The `broken' flag value 16 omits this feature
807 (the used PostScript command `setpagedevice' is a LanguageLevel 2
808 extension) -- if you intend to further process grops output to get an
809 encapsulated PS (EPS) file you must also use this option.
811 Patch by Egil Kvaleberg <egil@kvaleberg.no>.
813 o Non-slanted PostScript metrics have been changed again; they no longer
814 contain negative left italic correction values. This assures correct
820 o The font cmtex10 has been added as the special font `SC' to the DVI fonts.
821 It is used as a font-specific special font for CW and CWI.
823 o New options -l and -p to set landscape orientation and the paper size.
824 grodvi now emits a `papersize' special which is understood by DVI drivers
827 Consequently, the DESC file should contain a `papersize' keyword.
829 o The glyph shapes for \[*f] and \[*e] have been exchanged with \[+f] and
830 \[+e], respectively, to be in sync with all other devices.
832 o Glyphs \[HE] and \[DI] have been replaced with \[u2662] and \[u2661],
833 respectively, since the former two glyphs have a black (filled) shape
834 which grodvi doesn't provide by default (it never has actually).
839 o The glyphs \[*e] and \[+e] have been exchanged to be in sync with
842 o The glyph \[~=] is now called \[|=]. Similar to other devices, \[~=]
843 is now another name for glyph \[~~].
848 o New option `-r'. It is similar to the -i option except it tells grotty to
849 use the `reverse video' attribute to render italic fonts.
854 o New command `figname' to set the name of a picture's output box in TeX
860 o The environment variable `REFER' to override the name of the default
861 database isn't new but hasn't been documented before.
866 o New option `-r' to avoid emission of `.lf' lines.
868 o New option `-t' to emit TeX comment lines (giving current file and the
869 line number) instead of `.lf' lines.
874 o Unencoded glyphs in an AFM file are output also (since grops can now emit
875 multiple encoding vectors for a single font).
877 o New option `-m' to prevent negative left italic correction values.
879 o The mapping and encoding file together with file `DESC' are now searched
880 in the default font directory also. Please refer to the man page of
881 afmtodit for more details.
886 o Larry Kollar <kollar@alltel.net> and others made the man macros more
889 . New command line options -rFT, -rIN, and -rSN to set the vertical
890 location of the footer line, the body text indentation, and the
891 sub-subheading indentation.
893 . New command line option -rHY (similar to the ms macros) to control
896 . New macros `.PT' and `.BT' to print the header and footer strings.
897 They can be replaced with a customized version in `man.local'.
899 . The string `HF' now holds the typeface to print headings and
902 . Similar to the ms macros, the LT register now defaults to LL if not
903 explicitly specified on the command line.
905 o troff's start-up file `troffrc' now includes `papersize.tmac' to set
906 the paper size with the command line option `-dpaper=<size>'.
908 Possible values for `<size>' are the same as the predefined `papersize'
909 values in the DESC file (only lowercase; see the groff_font man page)
910 except a7-d7. An appended `l' (ell) character denotes landscape
911 orientation. Examples: `a4', `c3l', `letterl'.
913 Most output drivers need additional command line switches `-p' and
914 `-l' to override the default paper length and orientation as set in
915 the driver specific DESC file.
917 For example, use the following for PS output on A4 paper in landscape
920 groff -Tps -dpaper=a4l -P-pa4 -P-l -ms foo.ms > foo.ps
929 o The non-slanted PostScript font definition files have been regenerated to
930 include left and right italic correction values. Applying those to a
931 glyph (this is, prepending the glyph with `\,' and appending `\/' to the
932 glyph) sets the glyph width to the real value given by the horizontal
933 bounding box values. Without those escapes, the advance width for the
934 particular glyph is used (which can differ considerably).
936 Most users will neither need this feature nor notice a difference in
937 existing documents (provided \, and \/ is used as advertised, namely for
938 italic fonts only); its main goal is to improve image generation with
941 This is an experimental change, and feedback is welcome.
946 o Added global option `nospaces' to ignore leading and trailing spaces in
952 o The option -w (--linewidth) has been added (similar to other device
953 drivers) to set the default line width.
958 o Support for b-spline and Bezier curves has been added.
963 o New option `--shell' to select the shell under which groffer shall run.
968 o The string `Am' (producing an ampersand) has been added to mdoc for
969 compatibility with NetBSD.
971 o `.IX' is now deprecated for mom; you should use `.IQ' (Indent Quit)
974 o In mom, new inlines `FWD', `BCK', `UP', and `DOWN' deal with horizontal
975 and vertical movements; please refer to contrib/mom/NEWS for more
978 o New macro ENDNOTES_HDRFTR_CENTER for mom to better control headers.
983 o The `papersize' keyword in the DESC file now accepts multiple arguments.
984 It is scanned from left to the right, and the first valid argument is
985 used. This makes it possible to provide a fallback paper size.
989 papersize /etc/papersize a4
991 o A local font directory has been prepended to the default font path; it
992 defaults to /usr/local/share/groff/site-font. Similar to the normal
993 font searching process, files must be placed into a devXXX subdirectory,
996 /usr/local/share/groff/site-font/devps/FOO
998 for a PostScript font definition file FOO.
1004 ***************************************************************************
1006 * PLEASE READ THE CHANGES BELOW REGARDING GROTTY, GROFF'S TTY FRONTEND. *
1008 ***************************************************************************
1013 o Color support has been added to troff and pic (and to the device drivers
1014 grops, grodvi, grotty, and grohtml -- other preprocessors and drivers will
1015 follow). A new function `defcolor' defines colors; the escape sequence
1016 `\m' sets the drawing color, the escape sequence `\M' specifies the
1017 background color for closed objects created with \D'...' commands.
1018 `\m[]' and `\M[]' switch back to the previous color. `\m' and `\M'
1019 correspond to the new troff output command sets starting with `m' and
1020 `DF'. The device-specific default color is called `default' and can't be
1023 Use the `color' request to toggle the usage of colors (default is on); the
1024 read-only register `.color' is 0 if colors are not active, and non-zero
1027 The old `Df' output command is mapped onto `DFg'; all color output
1028 commands don't change the current font position (consequently, `Df'
1031 Outputting color can be disabled in troff and groff with the option -c
1032 (it is always disabled in compatibility mode). See the section on grotty
1033 for the GROFF_NO_SGR environment variable also.
1035 For defining color components as fractions between 0 and 1, a new scaling
1036 indicator `f' has been introduced: 1f = 65536u. For testing whether a
1037 color is defined (with .if and .ie), a new conditional operator `m' is
1040 More details can be found in the groff_diff.7 manual page and in
1043 o Similar to \m and \M, \f[] switches back to the previous font. \fP
1044 (and \f[P]) is still valid for backwards compatibility.
1046 o The new escape \F is the same as `.fam'; \F[] switches back to previous
1047 family -- \F[P] selects family `P'.
1049 o Two new glyph symbols are available: `eu' is the official Euro symbol;
1050 `Eu' is a font-specific glyph variant.
1052 o The new glyph symbols `t+-', `tdi', and `tmu' are textual variants of
1053 `+-', `di', and `mu', respectively.
1055 o Latin-1 character 181 (PS name `mu', Unicode name U+00B5 MICRO SIGN) has
1056 got the troff glyph name `mc'.
1058 o -Tutf8 is now available on EBCDIC hosts.
1060 o Strings can take arguments, using this syntax: \*[foo arg1 arg2 ...].
1063 .ds xxx This is a \\$1 test.
1066 o It is now possible to have whitespace between the first and second dot (or
1067 the name of the ending macro) to end a macro definition. Example:
1073 . nop Hello, I'm `foo'.
1074 . nop I will now define `bar'.
1076 . nop Hello, I'm `bar'.
1080 o `.fn' is a new string-valued register which returns the (internal) real
1081 font name; styles and families are properly concatenated.
1083 o Three new read/write registers `seconds', `minutes', and `hours' contain
1084 the current time, set at start-up of troff. Use the `af' request to
1085 control their output format.
1087 o The new request `fchar' can be used to provide fallback characters. It
1088 has the same syntax as the `char' request; the only difference is that a
1089 character defined with `.char' hides the glyph with the same name in the
1090 current font, whereas a character defined with `.fchar' is checked only if
1091 the particular glyph isn't found in the current font. This test happens
1092 before checking special fonts.
1094 o In analogy to the `tmc' request, `.writec' is the same as `.write' but
1095 doesn't emit a final newline.
1097 o The new request `itc' is a variant of `.it' for which a line interrupted
1098 with \c counts as one input line.
1100 o Two new requests `ds1' and `as1' which are similar to `ds' and `as' but
1101 with compatibility mode disabled during expansion of strings defined by
1104 o The syntax of the `substring' request has been changed: The first
1105 character in a string now has index 0, the last character has index -1.
1106 Note that this is an incompatible change.
1108 o To emit strings directly to the intermediate output, a new `output'
1109 request has been added; it is similar to `\!' used at the top level.
1111 o `.hpf' has been extended. It can now handle most TeX hyphenation
1112 pattern files without modification. To do that, the commands \patterns,
1113 \hyphenation, and \endinput are recognized. Please refer to groff_diff.7
1114 for more information.
1116 o `hpfcode' is a new request to provide an input encoding mapping for the
1119 o The new request `hpfa' appends hyphenation patterns (`hpf' replaces
1120 already existing patterns).
1122 o A new request `ami' (append macro indirect) has been added. The first and
1123 second parameter of `ami' are taken from string registers rather than
1124 directly; this very special request is needed to make `trace.tmac'
1125 independent from the escape character (which might even be disabled).
1127 o The new request `sizes' is similar to the `sizes' command in DESC files.
1128 It expects the same syntax; the data must be on a single line, and the
1129 final `0' can be omitted.
1131 o `trin' (translate input) is a new request which is similar to `tr' with
1132 the exception that the `asciify' request uses the character code (if
1133 any) before the character translation. Example:
1145 The result is `x a'. Using `tr', the result would be `x x'.
1147 o The request `pvs' isn't new, but hasn't been documented before. It
1148 adds vertical space after a line has been output. This makes it an
1149 alternative to the `ls' request to produce double-spaced documents.
1150 The read-only register `.pvs' holds the current amount of the
1151 post-vertical line space.
1153 o For compatibility with plan 9's troff, multiple `pi' requests are
1159 is now equivalent to
1163 o A new escape sequence `\O' is available to disable and enable glyph
1164 output. Please see groff_diff.7 and groff.texinfo for more details.
1166 o The escapes `\%', `\&', `\)', and `\:' no longer cause an error in \X;
1167 they are ignored now. Additionally `\ ' and `\~' are converted to
1168 single space characters.
1170 o The default tab distance in nroff mode is now 0.8i to be compatible
1173 o Using the latin-1 input character 0xAD (soft hyphen) for the `shc'
1174 request was a bad idea. Instead, it is now translated to `\%', and
1175 the default hyphenation character is again \[hy]. Note that the glyph
1176 \[shc] is not useful for typographic purposes; it only exists to have
1177 glyph names for all latin-1 characters.
1182 o Peter Schaffter <df191@ncf.ca> has contributed a new major macro package
1183 called `mom', mainly for non-scientific writers, which takes care of
1184 many typographic issues. It comes with a complete reference (in HTML
1185 format) and some examples. `mom' has been designed to format documents
1186 for PostScript output only.
1188 o Two macros `AT' (AT&T) and `UC' (Univ. of California) have been added to
1189 the man macros for compatibility with older BSD releases.
1191 o Both the man and mdoc macro packages now use the LL and LT registers for
1192 setting the line and title length, respectively (similar to those
1193 registers in the ms macro package). If not set on the command line or
1194 in a macro file loaded before the macro package itself, they default to
1195 78n in nroff mode and 6.5i in troff mode.
1197 o The `-xwidth' specifier in the mdoc macro package has been removed. Its
1198 functionality is now integrated directly into `-width'. Similarly,
1199 `-column' has been extended to provide this functionality also.
1201 o A new macro `Ex' has been added to the mdoc macro package to document an
1204 o The PSPIC macro has been extended to work with DVI output (`pspic.tmac' is
1205 now automatically loaded for -Tdvi), using a dvips special to load the EPS
1208 o The trace.tmac package now traces calls to `am' also. Additionally, it
1209 works in compatibility mode.
1211 o `troff.1' has been split. Differences to UNIX troff are now documented
1212 in the new man page `groff_diff.7'.
1214 o `groff_mwww.7' has been renamed to `groff_www.7'. The file mwww.tmac
1217 o `groff_ms.7' has been completely rewritten. It now contains a complete
1218 reference to the ms macros.
1220 o `groff_trace.7' documents the trace macro package.
1222 o Changes in www.tmac:
1224 Note that HTML support is still in alpha change, so it is rather likely
1225 that both macro names and macro syntax will change. Some of the macros
1226 mentioned below aren't really new but haven't been documented properly
1229 The following macros have been renamed:
1235 For consistency, the macros `URL', `FTL', and `MTO' now all have the
1236 address as the first parameter followed by the description.
1238 By default, grohtml generates links to all section headings at the top
1239 of the document. Use the new `LK' macro to specify a different place.
1241 For specifying the background color and a background image, use the
1242 new macros `BCL' and `BGIMG', respectively.
1244 The macro `NHR' has been added; it suppresses the generation of top and
1245 bottom rules which grohtml emits by default.
1247 The new macro `HX' determines the cut-off point for automatic link
1248 generation to headings.
1250 The image position parameter names in `IMG' have been changed to `-L',
1253 New macro `PIMG' for inclusion of a PNG image (it automatically
1254 converts it into an EPS file if not -Thtml is used).
1256 New macro `MPIMG' for putting a PNG image into the left or right margin
1257 (it automatically converts it into an EPS file if not -Thtml is used).
1259 New macros `HnS', `HnE' to start and end a header line block.
1261 New macro `DC' to produce dropcap characters.
1263 New macro `HTL' to generate an HTML title line only but no H1 heading.
1265 New macros `ULS' and `ULE' to start and end an unordered list. The new
1266 macro `LI' inserts a list item.
1271 o The new command line option `-c' disables color output (which is always
1272 disabled in compatibility mode).
1277 o Two new command line options `-c' and `-C'; the former passes `-c' to
1278 grotty (switching to the old output scheme); the latter passes `-C' to
1279 groff (enabling compatibility mode).
1284 o New keywords `color' (or `colour', `colored', `coloured'), `outline' (or
1285 `outlined'), and `shaded' are available. `outline' sets the color of the
1286 outline, `shaded' the fill color, and `color' sets both. Example:
1288 circle shaded "green" outline "black" ;
1290 Filled arrows always use the outline color for filling.
1292 Color support for TeX output is not implemented yet.
1297 o A new script contributed by Eric S. Raymond <esr@thyrsus.com>. It
1298 converts a PIC diagram into a cropped image. Since it uses gs and the PNM
1299 library, virtually all graphics formats are available for output.
1304 o A new script contributed by Eric S. Raymond <esr@thyrsus.com>. It
1305 converts an EQN diagram into a cropped image. Since it uses gs and the PNM
1306 library, virtually all graphics formats are available for output.
1311 o A new script contributed by Bernd Warken <bwarken@mayn.de>. It displays
1312 groff files and man pages on X and tty, taking care of most parameters
1318 o Documents using the mom macro package are recognized.
1323 o Color support has been added.
1325 o A new option `-p' is available to select the output paper size. It has
1326 the same syntax as the new `papersize' keyword in the DESC file.
1331 o By default, font sizes are now available in the range 5-10000pt, similar
1332 to PS fonts. If you want the old behaviour (i.e., font sizes at discrete
1333 values only), insert the following at the start of your document:
1336 . sizes 500 600 700 800 900 1000 1095 1200 1400 1440 1600 \
1337 1728 1800 2000 2074 2200 2400 2488 2800 3600
1339 o A new font file HBI (using cmssbxo10; this is slanted sans serif bold
1340 extended) has been added.
1342 o Two font families are now available: `T' and `H'.
1344 o EC and TC fonts have been integrated. Use `-mec' (calling the file
1345 ec.tmac) to switch to them. Those fonts give a much better coverage of
1346 the symbols defined by groff than the CM fonts.
1348 Note that ec.tmac must be called before any language-specific files; it
1349 doesn't take care of hcode values.
1351 o Color support has been added. For drawing commands, colors are translated
1352 to gray values currently.
1357 o Color support has been added, using the SGR (ISO 6429, sometimes called
1358 ANSI color) escape sequences.
1360 o SGR escape sequences are now used by default for underlining and bold
1361 printing also, no longer using the backspace character trick. To revert
1362 to the old behaviour, use the `-c' switch.
1364 Note that you have to use the `-R' option of `less' to make SGR escapes
1365 display correctly. On the other hand, terminal programs and consoles like
1366 `xterm' which support SGR sequences natively can directly display the
1367 output of grotty. Consequently, the options `-b', `-B', `-u', and `-U'
1368 work only in combination with `-c' and are ignored silently otherwise.
1370 For the `man' program, it may be necessary to add the `-R' option of
1371 `less' to the $PAGER environment variable (or $MANPAGER, depending on the
1372 used `man' program); alternatively, you can use `man's `-P' option (or
1373 adapt its configuration file accordingly). See man(1) for more details.
1375 o If the environment variable GROFF_NO_SGR is set, SGR output is disabled,
1376 reverting to the old behaviour.
1378 o A new special \X'tty: sgr n' has been added; if n is non-zero or missing,
1379 enable SGR output (the default).
1381 o If the new option `-i' is used (only in SGR mode), grotty sends escape
1382 sequences to set the italic font attribute instead of the underline
1383 attribute for italic fonts. Note that many terminals don't have support
1384 for this (including xterm).
1389 o Color support for glyphs has been added.
1391 o New option `-h' to select the style of headings in HTML output.
1393 o New option `-b' to set the background colour to white.
1395 o New options `-a' and `-g' to control the number of bits for anti-aliasing
1396 used for text and graphics, respectively. Default value is 4; 0 means
1399 o groff character/glyph entities now map onto HTML 4 character entities.
1404 o Valid paper sizes are now specified as with the new `papersize' keyword
1405 in the DESC file. Specifically, the old custom paper type format
1406 `custAAAxBBB' is no longer supported.
1411 o A new manual page `ditroff.7' is available.
1413 o The groff texinfo manual is installed now, together with a bunch
1416 o A new keyword `papersize' has been added to the DESC file format. Its
1419 . a predefined paper format (e.g. `A4' or `letter')
1421 . a file name pointing to a file which must contain a paper size
1422 specification in its first line (e.g. `/etc/papersize')
1424 . a custom paper size definition like `35c,4i'
1426 See groff_font(5) for more details. This keyword only affects the
1427 physical dimensions of the output medium; grops, grolj4, and grolbp use it
1428 currently. troff completely ignores it.
1434 This is major bug-fixing release which should replace 1.17.1.
1439 o The `IMAGE' macro in www.tmac has changed: Now the optional 2nd parameter
1440 gives the horizontal image location (left, centered, or right), and the
1441 optional 3rd and 4th parameter the image dimensions.
1447 This is mainly a bug-fixing release.
1452 o Two new requests `de1' and `am1' which are similar to `de' and `am' but
1453 with compatibility mode disabled during expansion of macros defined by
1456 o Added request `brp'. This is the same as `\p'.
1458 o Similar to other versions of troff, the `ns' request now works in all
1459 diversions, not only in the top-level one.
1461 o New read-only number register `.ns'. Returns 1 if in no-space mode,
1467 o Options -p (pic) and -t (tbl) added.
1469 o The environment variable GROFF_BIN_PATH is now checked before PATH for
1475 o New option `-D dir' to specify a directory in which all images are placed.
1477 o New option `-I stem' to specify an image name stame. If not given,
1478 `grohtml-XXX' is used (`XXX' is the process ID).
1487 o `-mFOO' now searches first for `FOO.tmac' and then for `tmac.FOO'. The
1488 old behaviour has been changed to overcome problems with platforms which
1489 have an 8+3 file name limit, and platforms which have other versions of
1490 troff installed also. Additionally, all macro files have been renamed
1491 using the latter scheme to avoid 8+3 name clashes.
1493 o The new environment variable GROFF_BIN_PATH is checked for programs groff
1494 is calling (preprocessors, troff, and output devices) before PATH. If not
1495 set, it defaults to the directory where the groff binary is located.
1496 Previously, it was PATH only. The nroff script only uses GROFF_BIN_PATH
1497 to find the groff binary but passes both the GROFF_BIN_PATH and PATH
1498 environment variables to groff.
1503 o The mdoc package has been completely rewritten, using the full power of
1504 GNU troff to remove limitations of Unix troff (which is no longer
1505 supported). Most important changes are:
1508 . Almost all macros are parsed and callable (if it makes sense)
1509 . `.Lb': prints library names
1510 . `.Nm <punctuation>' now works as expected; `.Nm "" <punctuation>' has
1512 . Updated `.St' command
1513 . `.Fx': prints FreeBSD
1514 . `.Ox': prints OpenBSD
1515 . `.Bsx': prints BSD/OS
1516 . `.Brq', `.Bro', `.Brc': brace enclosure macros
1517 . `.Bd -centered': center lines
1518 . `.Bl -xwidth <string>': interpret <string> and use the resulting width
1519 . Support for double-sided printing (-rD1 command line switch)
1520 . Support for 11pt and 12pt document sizes (-rS11, -rS12 command line
1523 `groff_mdoc.7' replaces `groff_mdoc.samples.7'; it now completely
1524 documents the mdoc package.
1526 Great care has been taken to assure backwards compatibility. If you
1527 encounter any abnormal results, please report them to bug-groff@gnu.org.
1529 o A new command line option for the `man' macros (similar to the `mdoc'
1530 package) has been implemented: `-rcR=1' (now the default in nroff mode)
1531 produces one single, very long page instead of multiple pages. `-rcR=0'
1534 o The `return' request has been added to return immediately from a macro.
1536 o A new request `nop' (no operation) has been added which is similar to
1537 `if 1'. For example,
1543 can now be written as
1549 o `box' and `boxa' are two new requests which behave similarly to `di' and
1550 `da' but don't include a partially filled line (which is restored after
1551 ending the diversion).
1553 o The `asciify' request has been extended to `unformat' space characters
1554 and some other escape sequences also.
1556 `\ ' is no longer unformatted as a space but remains an unpaddable,
1557 unbreakable space character.
1559 o The new `unformat' request is similar to `asciify' but only handles space
1560 characters and tabs specially if the diversion is reread, retaining font
1561 information. This makes it possible to reformat diversions; for example
1566 a01 a02 a03 a04 a05 a06 a07 a08 a09 a10.
1571 \f[B]b01 b02 b03 b04 b05 b06 b07 b08 b09 b10.\f[P]
1576 c01 c02 c03 c04 c05 c06 c07 c08 c09 c10.
1583 a01 a02 a03 a04 a05 a06 a07
1584 a08 a09 a10. c01 c02 c03 c04
1585 c05 c06 c07 c08 c09 c10. b01
1586 b02 b03 b04 b05 b06 b07 b08
1589 Without the `unformat' request, space characters are converted to word
1590 space nodes which are no longer stretchable, and the result would be
1592 a01 a02 a03 a04 a05 a06 a07
1593 a08 a09 a10. c01 c02 c03 c04
1594 c05 c06 c07 c08 c09 c10. b01
1595 b02 b03 b04 b05 b06 b07 b08
1598 o The new request `linetabs' controls the `line-tabs' mode. In line-tabs
1599 mode, tab distances are computed relative to the (current) output line.
1600 Otherwise they are taken relative to the input line. For example, the
1615 In line-tabs mode, the same code gives
1619 The new read-only number register `.linetabs' returns 1 if in line-tabs
1620 mode, and 0 otherwise.
1622 o Two new requests `tm1' and `tmc' have been added to improve writing
1623 messages to the terminal. `tm1' is similar to `tm' but allows leading
1624 whitespace. `tmc' is similar to `tm1' but doesn't emit a final newline.
1626 o For compatibility with sqtroff, the request `output' has been added.
1627 The behaviour is similar to `\!' at the top-level, that is, it directly
1628 inserts its argument into the intermediate output format. The syntax
1629 is similar to .tm1, allowing leading whitespace.
1631 o The new `spreadwarn' request makes troff warn if spaces in an output
1632 line are widened by a given limit or more.
1634 o Use `warnscale' to change the scaling indicator troff uses for
1637 o A new request `dei' (define indirect) has been added. The first and
1638 second parameter of `dei' are taken from string registers rather than
1639 directly; this very special request is needed to make `trace.tmac'
1640 independent from the escape character (which might even be disabled).
1642 o It is now possible to save and restore the escape character with two new
1643 requests `ecs' and `ecr'.
1645 o The new escape sequence \B'...' is an analogon to `\A': If the string
1646 within the delimiters is a valid numeric expression, return character `1',
1649 o The new escape sequence `\:' inserts a zero-width break point. This is
1650 similar to `\%' but without a soft hyphen character.
1652 o The `tr' request can now map characters onto `\~'.
1654 o Calling the `fam' request without an argument switches back to the
1655 previous font family.
1657 o The new read-only register `.int' is set to a positive value if the last
1658 output line is interrupted (i.e., if the input line contains `\c').
1660 o The `writem' request is not new, but hasn't been documented before. This
1661 is similar to `write' but instead of a string the contents of a given
1662 macro or string is written to a stream.
1664 o The read/write number register `hp' to get/set the current horizontal
1665 position relative to the input line isn't new but hasn't been documented
1668 o `\X' and `\Y' are now transparent for end-of-sentence recognition.
1670 o The `cu' request in nroff mode now works as documented (i.e., it
1671 underlines spaces also).
1676 o The grog script now works in non-compatibility mode also (which is the
1677 default). As usual, use the `-C' option to activate compatibility mode.
1682 o A new option `-P' resp. a new environment variable `GROPS_PROLOGUE' has
1683 been added to select a different prologue file.
1685 o The effect of the former `-mpsnew' option to access more Type 1 characters
1686 is now the default and no longer available. To get the old behaviour
1687 (i.e., emulation of some glyphs by composition) use `-mpsold'.
1692 o For security reasons the following changes have been done:
1694 . The tmac.safer file has been replaced with a built-in solution; .open,
1695 .opena, .pso, .sy, and .pi are completely disabled in safer mode (which
1696 is the default); to enable these requests the `-U' command line flag
1699 . Files specified with the .mso request or given with the `-m' command
1700 line option, and hyphenation patterns loaded with `.hpf' are no longer
1701 searched in the current directory by default (besides the usual tmac
1702 path). Instead, the home directory is used. To add the current
1703 directory, either use the `-U' or `-M' command line option or set the
1704 GROFF_TMAC_PATH environment variable to an appropriate value.
1706 . troffrc, troffrc-end, and eqnrc are neither searched in the current nor
1707 in the home directory (even if -U is given). Use -M or GROFF_TMAC_PATH
1710 . Similarly, the current directory is no longer part of the font path.
1711 Use the `-F' command line option or the GROFF_FONT_PATH environment
1712 variable if you really need the current directory.
1714 o groff now installs its data files into /usr/local/share/groff/<version> by
1715 default, following the GNU standard. Additionally, a local tmac directory
1716 (by default /usr/local/share/groff/site-tmac) is scanned before the
1717 standard tmac directory. Wrapper files for system-specific macro packages
1718 (if necessary) are put into /usr/local/lib/groff/site-tmac; this directory
1719 is searched before the local tmac directory.
1721 o All programs now have option `-v' to show the version number; they exit
1722 immediately afterwards, following the GNU standards. Additionally,
1723 `--version' and `--help' have been added, doing the obvious actions.
1729 Bug fixes only; no user-visible changes.
1738 The anachronism of calling the man macro package with `-man' has been fixed;
1739 now you can say `-m man' also. The same is true for `ms', `me', `markup',
1740 `mandoc', and `mdoc'.
1742 A new switch `-g' for calling `grn' is available.
1744 A new switch `-G' for calling `grap' is available.
1746 EBCDIC support for tty devices has been added. On such hosts, IBM code page
1747 1047 is available with -Tcp1047 instead of -Tascii and -Tlatin1 (and, for
1748 the moment, -Tutf8). Note that non-tty devices are not yet supported (but
1754 A new command line option to the `man' macros is available: `-rSxx' (with
1755 `xx' either 10, 11, or 12) to set the base document font size to `xx'
1756 points. Additionally, `.SH' now produces larger headings than `.SS'.
1758 To solve a problem with the .PSPIC macro which needs the `-U' switch of
1759 troff to access an external program (psbb), a new request .psbb is now
1760 available to get the bounding box of a PostScript image file. The values
1761 (in PostScript units) are returned in the new read-only number registers
1762 `llx', `lly', `urx', and `ury'. Consequently, .PSPIC has been adapted to
1763 use the new request, and the psbb program has been removed.
1765 A new predefined writable number register, `year', has been added. It
1766 contains the current year.
1768 A new read-only register, `.Y', has been added. It contains the revision
1769 number of the groff package.
1771 `\fP' now behaves as expected in situations like the following where the
1772 font `foo' is undefined:
1775 normal text \f[foo]bar\fP normal text
1777 Previously, the text after \fP appeared as bold.
1779 The `substring' request is not new, but hasn't been documented before.
1781 The predefined `.T' string register (which holds the current output device)
1782 is not new, but hasn't been documented before.
1784 A new request `length' computes the length of a string and returns it in
1787 The macro files `tmac.a4' (for specifying A4 paper format) and `tmac.trace'
1788 (a debugging aid) are now installed also.
1790 A new resource file, `troffrc-end', is now available. It is invoked after
1791 all user-specified macros. Currently used by the html device to include
1792 tmac.html; thus no need for users to specify -mhtml anymore.
1794 The soft hyphen character now has a glyph name: `shc'.
1796 The latin-1 character 173 (PS name `periodcentered') has got the troff glyph
1797 name `pc' and is no longer intermixed with the symbol character `md' (PS
1800 ASCII character 34 (PS name `quotedbl') has got the troff glyph name `dq'
1801 (which is an alias to character `"').
1803 ASCII character 39 (PS name `quoteright') has got the troff glyph name `cq'
1804 (which is an alias to character "'").
1806 Some additions to the font description files have been implemented for
1807 better support of HTML output:
1809 The new format of lines in the `charset' subsection of font description
1812 name metrics type code [entity_name] [-- comment]
1814 Currently, only the font description files in devhtml use the optional
1815 entity_name string to define glyph entities in HTML. Everything after the
1816 entity_name field is ignored; in case this field isn't used, two hyphen
1817 characters are now necessary to start a comment.
1819 Two new requests are available in DESC files (currently used only with
1822 use_charnames_in_special
1823 This command indicates that troff should encode named characters
1824 inside special commands.
1827 requests that troff tells the driver the source file name being
1828 processed. This is achieved by another tcommand: `F filename'.
1833 Bruno Haible <haible@clisp.cons.org> contributed support for UTF8 output.
1838 Added .LINE macro to tmac.arkup.
1840 The obsolete `.LINK' macro has been removed.
1842 .URL, .FTP, and .MAILTO macros now accept an optional third argument which
1843 is immediately appended to the second argument (to be used with
1844 punctuation, for example).
1849 The font size 11pt has been changed to 10.95pt (as used in LaTeX 2e).
1851 A new font file CWI (using cmitt10; this is typewriter italic) has been
1857 A new driver for Canon CAPSL printers (LBP-4 and LBP-8 series laser
1858 printers). This code has been contributed by Francisco Andres Verdu
1859 <pandres@dragonet.es>.
1864 A new preprocessor to process gremlin pictures. It is based on the
1865 original Berkeley implementation of grn, written by David Slattengren
1866 and Barry Roitblat, and has been adapted to groff by Daniel Senderowicz
1867 <daniel@synchrods.com> and Werner Lemberg <wl@gnu.org>.
1872 Added the `srand' command to set the seed for a new sequence of
1873 pseudo-random numbers to be returned by `rand'.
1878 Simplified installation: The Imakefile is now configured (by groff's
1884 Three new man pages are available: groff_tmac.5 (documenting how troff macros
1885 are accessed and where they are found), groff.7 (a short reference of the GNU
1886 roff language), and roff.7 (a general survey on GNU troff).
1891 A partial port to win32 (for use with Microsoft Visual C++ 6.0) is now part
1892 of the distribution. It has been contributed by Blake McBride
1893 <blake@florida-software.com>.
1895 More information about programs, macros, documentation, etc., which is
1896 related to groff has been collected in the file `MORE.STUFF'.
1899 VERSION 1.13, 1.14, 1.15
1900 ========================
1902 Bug fixes only; no user-visible changes.
1908 Finally, there are new maintainers for groff. Mailing lists and a CVS
1909 repository are available also. See the file README for details. Not all
1910 reported bugs could be fixed, so please send mails again if something is
1913 Most of the installation problems should have vanished now (most
1914 notably the $(tmac_wrap) bug).
1916 There is now a man page called groff_man.7 which documents the basics of the
1917 -man macros. It has been originally written by Susan G. Kleinmann
1920 A (still incomplete) groff reference manual in texinfo format originally
1921 contributed by Trent A. Fisher <trent@gnurd.portland.or.us>.
1923 me.man and msafer.man have been renamed to groff_me.man
1924 resp. groff_msafer.man for consistency.
1926 Default strings for macros in doc-common resp. tmac.an no longer contain the
1929 groff should now be Y2k safe (fixes contributed by Paul Eggert
1930 <eggert@twinsun.com>).
1932 Following the GNU standards, groff now uses the prefix `/usr/local/' as
1933 the default instead of replacing an existent groff binary.
1935 groff, troff, nroff, and pic now support the -U flag to activate unsafe
1936 behaviour (without -msafer); the -S flag for using the -msafer macros is now
1942 This is a new output device for producing HTML output contributed by Gaius
1943 Mulley <gaius@glam.ac.uk>. It is still very alpha but has been included
1944 into the distribution so that a lot of people have a chance to test it. Bug
1945 reports are highly welcome.
1950 Duplex printing support has been contributed by Jeffrey Copeland
1956 Added -I option for defining include paths (patch contributed by Peter
1957 Miller <peterm@jna.com.au>).
1962 Fallback resources added (patch contributed by Larry Jones
1963 <larry.jones@sdrc.com>).
1965 Will now support 8 gray levels.
1970 New version 1.32 (contributed by Joergen Haegg <jh@axis.com>).
1976 Complete documentation for pic is now in the file doc/pic.ms. It was
1977 contributed by Eric S. Raymond, <esr@thyrsus.com>, who is emphatically
1978 *not* volunteering to take over groff as he is way overworked with
1979 half a dozen other projects.
1985 The directory where data files are installed has been changed from
1986 /usr/local/lib/groff to /usr/local/share/groff to comply with the
1987 latest GNU coding standards.
1989 By default groff programs with Unix equivalents are installed with a
1990 "g" prefix unless there is an existing (non-groff) troff installation.
1992 A new approach is used to make system macro packages available to
1993 groff. Instead of simply including /usr/lib/tmac in the list of
1994 directories searched by groff, the installation process creates for
1995 each system macro package a wrapper macro package in the groff macro
1996 directory that references the system macro package. The groff macro
1997 packages are now installed with a leading "g" prefix if there is a
1998 system version of the same macro package, and otherwise without the
1999 "g" prefix, with the exception that the groff version of -me which is
2000 always installed as -me.
2002 There is a new device, lj4, for the HP LaserJet 4 (and PCL5
2008 groff has a -S option that prevents the use of unsafe features in pic
2009 and troff. This uses a new -S option of pic and the -msafer macros
2015 The `blm' request specifies a macro to be invoked when a blank line is
2021 A -S (safer) option disables the sh command.
2026 The -m option enables manual feed.
2032 \(rn now produces a character that has the traditional metrics,
2033 and form corners with \(ul and \(br. This means that it does not
2034 align properly with \(sr. Instead there's a new character
2035 \[radicalex] which aligns with \(sr; this is used by eqn for doing
2041 The `pso' request allows you to read from the standard output of a
2047 The PSPIC macro has options to allow the horizontal alignment of the
2048 graphic to be specified.
2057 The escape sequence \V[xxx] interpolates the value of the
2058 environment variable xxx.
2063 The decimalpoint option can be used to specify the character to be
2064 recognized as the decimal point character in place of the default
2074 The environment variable GROFF_COMMAND_PREFIX can be used to control
2075 whether groff looks for `gtroff' or `troff' (similarily for the
2081 Multilingual hyphenation is supported by new `hpf' and `hla' requests,
2082 and by a `\n[.hla]' number register. The -H option has been removed.
2083 Files of hyphenation patterns can have comments.
2085 When a font cannot be found, troff gives a warning (of type `font',
2086 enabled by default) instead of an error.
2088 There's a new request `trnt' that's like `tr' except that it doesn't
2089 apply to text transparently throughput into a diversion with \!.
2094 There is a `nokeep' option which tells tbl not to use diversions to
2095 try to keep the table on one page.
2100 Setting the parameter `nroff' to a non-zero value causes `ndefine' to
2101 behave like `define' and `tdefine' to be ignored. This is done by
2102 eqnrc when the current device is ascii or latin1. There's a `neqn'
2103 script that just does `eqn -Tascii'.
2108 grotty uses whatever page length was specified using the `pl' request
2109 rather than using the paperlength command in the DESC file. The
2110 paperwidth command in the DESC file is also ignored.
2116 The programs in groff that have Unix counterparts can now be installed
2117 without a leading `g' prefix. See the `g' variable in the Makefile.
2119 The g?nroff script simulates the nroff command using groff.
2121 New special characters \(+h, \(+f, \(+p, \(Fn, \(Bq, \(bq, \(aq, \(lz,
2122 \(an. See groff_char(7).
2124 ^L is now a valid input character.
2129 The Xps pseudo-device has disappeared. Instead there is a new -X
2130 option that tells groff to use gxditview instead of the usual
2131 postprocessor. (So instead of -TXps, use -XTps or just -X if your
2132 default device is ps.)
2134 The postprocessor to be used for a particular device is now specified
2135 by a `postpro' command in the DESC file rather than being compiled
2136 into groff. Similarly the command to be used for printing (with the
2137 -l option) is now specified by a `print' command in the DESC file.
2139 The groff command no longer specifies eqnchar as an input file for
2140 eqn. Instead eqn automatically loads a file `eqnrc'. The groff
2141 command no longer passes the -D option to eqn. Instead eqnrc sets the
2142 draw_lines parameter.
2144 The groff command no longer tells troff to load a device-specific
2145 macro file. This is handled instead by the `troffrc' file, which is
2146 always loaded by troff.
2148 The shell script version of groff has been removed.
2153 The `rchar' request removes a character definition established with `char'.
2155 Compatibility mode is disabled and the escape character is set to `\'
2156 while a character definition is being processed.
2158 The `\#' escape sequence is like `\"' except that the terminating
2161 The `shc' request tells troff which character to insert (instead of
2162 the default \(hy) when a word is hyphenated at a line break.
2164 A font name of 0 (zero) in the DESC file causes no font to be
2165 mounted on the corresponding font position. This is useful for
2166 arranging that special fonts are mounted on positions on which users
2167 are not likely explicitly to mount fonts. All groff devices now avoid
2168 initially mounting fonts on positions 5-9.
2170 The `do' request allows a single request or macro to be interpreted
2171 with compatibility mode disabled.
2173 troff automatically loads a file `troffrc' before any other input file.
2174 This can be prevented with the -R option. This file is responsible
2175 for loading the device-specific macros.
2180 The -x option has been removed and a -n option has been added. By
2181 default, pic now assumes that the postprocessor supports groff
2182 extensions. The -n option tells pic to generate output that works
2183 with ditroff drivers. The -z option now applies only to TeX mode.
2185 The -p option has been removed. Instead if the -n option is not
2186 specified, pic generates output that uses \X'ps: ...' if the \n(0p
2187 register is non-zero and tmac.ps sets this register to 1.
2189 In places where you could 1st or 5th you can now say `i'th or `i+1'th
2190 (the quotes are required).
2195 Eqn now automatically reads a file `eqnrc' from the macro directory.
2196 This performs the same role that the eqnchar files used to. This can
2197 be prevented by the -R option.
2199 Setting the draw_lines parameter to a non-zero value causes lines to
2200 be drawn using \D rather than \l. The -D option is now obsolete.
2202 `uparrow', `downarrow' and `updownarrow' can be used with `left' and
2205 The amount of extra space added before and after lines containing
2206 equations can be controlled using the `body_height' and `body_depth'
2212 Font description files have been regenerated from newer AFM files.
2213 You can get access to the additional characters present in the text
2214 fonts in newer PostScript printers by using -mpsnew.
2216 The default value of the -b option is specified by a `broken' command
2219 With the -g option, grops generates PostScript code that guesses
2220 the page height. This allows documents to be printed on both letter
2221 (8.5x11) and A4 paper without change.
2226 ISO Latin-1 characters are available with -Tdvi. Format groff_char(7)
2227 with groff -Tdvi for more information.
2232 The -mtty-char macros contain additional character definitions for
2238 In previous releases the groff -me macros treated the $r and $R number
2239 registers in a way that was incompatible with the BSD -me macros. The
2240 reason for this was that the approach used by the BSD -me macros does
2241 not work with low resolution devices such as -TX75 and -TX100.
2242 However, this caused problems with existing -me documents. In this
2243 release, the vertical spacing is controlled by the $v and $V registers
2244 which have the same meaning as $r and $R in earlier groff releases.
2245 In addition, if the $r or $R register is set to a value that would be
2246 correct for for the BSD -me macros and a low resolution device is not
2247 being used, then an appropriate value for the $v or $V register
2248 is derived from the $r or $R register.
2250 The groff -me macros work with -C and (I think) with Unix troff.
2252 For backward compatibility with BSD -me, the \*{ and \*} strings are
2253 also available as \*[ and \*]. Of course, \*[ is only usable
2256 The \*T string has been deleted. Use \*(Tm instead.
2261 The `n', Space and Return keys are bound to the Next Page action. The
2262 `p', BackSpace and Delete keys are bound to the Previous Page action.
2263 The `q' key is bound to the Quit action.
2265 The `r' key is bound to a rerasterize action that reruns groff, and
2266 redisplays the current page.
2275 There is a alternative assignment operator `:=' which interacts
2276 differently with blocks.
2278 There is a new command `command', which allows the values of variables
2279 to be passed through to troff or TeX.
2281 The `print' command now accepts multiple arguments.
2283 String comparison expressions (using `==' or `!=') are allowed in more
2289 Horizontal and vertical lines drawn with \D'l ...' are rendered
2290 using -, | and + characters. This is intended to give reasonable
2291 results with boxed tables. It won't work well with pic.
2296 The -mdoc macros have been upgraded to the version in the second
2297 Berkeley networking release. This version is not completely
2298 compatible with earlier versions; the old version is still available
2299 as -mdoc.old. The grog script has been enhanced so that it can
2300 usually determine whether a document requires the old or new versions.
2302 With -TX75, -TX100 and -TXps, the PSPIC macro produces a box
2303 around where the picture would appear with -Tps.
2309 An implementation of the -mm macros is included.
2311 The directory in which temporary files are created can be controlled
2312 by setting the GROFF_TMPDIR or TMPDIR environment variables.
2317 Some MS-DOS support (see pic/make-dos-dist).
2322 There are two new \X commands (\X'ps: invis' and \X'ps: endinvis')
2323 which make it possible to have substitute characters that are
2324 displayed when previewing with -TXps but ignored when printing with
2330 Support for scalable fonts.
2336 No changes other than bug fixes.
2342 There is an implementation of refer and associated programs. groff -R
2343 preprocesses with grefer; no mechanism is provided for passing
2344 arguments to grefer because most grefer options have equivalent
2345 commands which can be included in the file. grog also supports refer.
2347 There is an alternative perl implementation of the grog script.
2349 The code field in lines in the charset section of font description
2350 files is now allowed to contain an arbitrary integer (previously it
2351 was required to lie between 0 and 255). Currently grops and grodvi
2352 use only the low order 8 bits of the value. Grodvi uses the
2353 complete value; however, this is unlikely to be useful with
2354 traditional TeX tools (.tfm files only allow 8 bit character codes.)
2356 Left and right double quotes can be obtained with \(lq and \(rq
2359 There is a new program called pfbtops which translates PostScript
2360 fonts in pfb format to ASCII.
2362 A slightly modified version of the Berkeley tmac.doc is included.
2367 In long escape names the closing ] is now required to be at the same
2368 input level as the opening [.
2370 The \A'S' escape sequence returns 1 or 0 according as S is or is not
2371 suitable for use as a name.
2373 \~ produces an unbreakable space that can be stretched when the line
2376 The `mso' request is like the `so' request except that it searches for
2377 the file in the same directories in which tmac.X is searched for when
2378 the -mX option is given.
2380 The escape sequence `\R' is similar to the `nr' request.
2385 A new `special' primitive allows you to add new types of unary
2386 constructs by writing a troff macro.
2391 The implementation no longer uses gperf.
2396 The compile-time -DBROKEN_SPOOLER option has been replaced by a
2397 BROKEN_SPOOLER_FLAGS option. This allows more precise control over
2398 how grops should workaround broken spoolers and previewers. There is
2399 a new -b option that can change this at run-time.
2401 Grops now generates PostScript that complies with version 3.0 of the
2402 Document Structuring Convention.
2404 The resource management component of grops (the part that deals with
2405 imported documents and downloadable fonts) has been rewritten and now
2406 supports version 3.0 of the Document Structuring Conventions. The

2411 tmac.psatk contains some macros that support the mechanism used by the
2412 Andrew Toolkit for including PostScript graphics in troff documents.
2417 Parts of xditview have been rewritten so that it can be used with the
2418 output of gtroff -Tps. groff -TXps runs gtroff -Tps with
2421 There is a new menu entry `Print' which brings up a dialog box for
2422 specifying a command with which the file being previewed should be
2425 Xditview now uses imake.
2431 The groff command now understands the gtroff `-a' and `-i' options.
2433 With the `m' and `n' scale indicators, the scale factor is rounded
2434 horizontally before being applied. This makes (almost) no difference
2435 for devices with `hor' equal to 1, but it makes groff with -Tascii or
2436 -Tlatin1 behave more like nroff in its treatment of these scale
2437 indicators. Accordingly tmac.tty now calls the `nroff' request so
2438 that the `n' condition is true.
2440 The device-specific macros (tmac.ps, tmac.dvi, tmac.tty and tmac.X)
2441 have been made to work at least somewhat with -C. In particular the
2442 special characters defined by these macros now work with -C.
2444 groff -Tdvi -p now passes pic the -x flag; this enables filling
2445 of arrowheads and boxes, provided that your dvi driver supports the
2446 latest version of the tpic specials.
2451 There is a new `-N' option that tells eqn not to allow newlines in
2452 delimiters. This allows eqn to recover better from missing closing
2453 delimiters. The groff command passes on a `-N' option to eqn.
2458 You can now use psfig with grops. See the file ps/psfig.diff. I do
2459 not recommend using psfig for new documents.
2461 The command \X'ps: file F' is similar to \X'ps: exec ...' except that
2462 the PostScript code is read from the file F instead of being contained
2463 within the \X command. This was added to support psfig.
2468 There are font files HB and HI corresponding to cmsssbx10 and cmssi10.
2473 The groff -me macros now work with the -C option. As a result, they
2474 may also work with Unix nroff/troff.
2476 In -me, the $r and $R number registers now contain the line spacing as
2477 a percentage of the pointsize expressed in units (normally about 120).
2478 The previous definition was useless with low resolution devices such
2485 A -ms-like macro-package is now included.
2487 The name for the Icelandic lowercase eth character has been changed
2493 There is a new request `nroff', which makes the `n' built-in condition
2494 true and the `t' built-in condition false; also a new request `troff'
2495 which undoes the effect of the `nroff' request. This is intended only
2496 for backward compatibility: it is usually better to test \n(.H or
2497 \n(.V or to use the `c' built-in condition.
2499 The \R escape sequence has been deleted. Use \E instead.
2501 There are `break' and `continue' requests for use with the `while'
2504 There is a request `hym' that can ensure that when the current
2505 adjustment mode is not `b' a line is not hyphenated if it is no
2506 more than a given amount short, and a request `hys' that can ensure
2507 that when the current adjustment mode is `b' a line is not
2508 hyphenated if it can be justified by adding no more than a given
2509 amount of extra space to each word space.
2511 There is a request `rj' similar to `ce' that right justifies lines.
2513 A warning of type `space' is given when a call is made to an
2514 undefined request or macro with a name longer than two characters, and
2515 the first two characters of the name make a name that is defined.
2516 This is intended to find places where a space has been omitted been a
2517 request or macro and its argument. This type of warning is enabled by
2523 A comma is permitted between the arguments to the `reset' command.
2525 For use with TeX, there is a new `-c' option that makes gpic treat
2526 lines beginning with `.' in a way that is more compatible with tpic
2532 It is no longer necessary to add `space 0' at the beginning of
2533 complicated equations inside pictures.
2535 `prime' is now treated as an ordinary character, as in Unix eqn. The
2536 previous behaviour of `prime' as an operator can now be obtained using
2542 There are two new devices X75-12 and X100-12 which are the same as X75
2543 and X100 except that they are optimized for documents that use mostly
2550 The installation process has been refined to make it easy for you to
2551 share groff with someone who has the same type of machine as you but
2552 does not have a C++ compiler. See the end of the INSTALL file for
2555 There is a man page for the tfmtodit program which explains how to use
2556 your own fonts with groff -Tdvi.
2558 There is a man page for afmtodit which explains how to use your own
2559 PostScript fonts with groff -Tps.
2561 The \N escape sequence is now fully supported. It can now be used to
2562 access any character in a font by its output code, even if it doesn't
2563 have a groff name. This is made possible by a convention in the font
2564 files that a character name of `---' refers to an unnamed character.
2565 The drivers now all support the `N' command required for this. The font
2566 description files have been updated to include unnamed characters.
2568 The `x' command in font description files has been removed: instead
2569 any unknown commands are automatically made available to the drivers.
2570 If you constructed your own font files with an earlier version of
2571 tfmtodit or afmtodit, you must construct them again using the current
2574 Characters between 0200 and 0237 octal are no longer valid input
2575 characters. Note that these are not used in ISO 8859.
2577 A command called `grog' has been added, similar to the `doctype'
2578 command described in Kernighan and Pike.
2583 The groff command has some new options: -V prints the pipeline
2584 instead of executing it; -P passes an argument to the postprocessor,
2585 -L passes an argument to the spooler.
2587 There is a C++ implementation of the groff command. This handles some
2588 things slightly better than the shell script. In particular, it can
2589 correctly handle arguments containing characters that have a special
2590 meaning to the shell; it can give an error message when child
2591 processes other than the last in the pipeline terminate abnormally;
2592 its exit status can take account of the exit statuses of all its child
2593 processes; it is a little more efficient; when geqn is used, it
2594 searches for the eqnchar file in the same way that font metric files
2595 are searched for, rather than expecting to find it in one particular
2601 There is font translation feature: For example, you can tell gtroff to
2602 use font `HR' whenever font `H' is requested with the line
2604 This would be useful for a document that uses `H' to refer to
2607 There are some new number registers: `.kern' contains the current kern
2608 mode, `.lg' the current ligature mode, `.x' the major version number,
2609 `.y' the minor version number, `.ce' the number of lines to be
2610 centered in the current environment, `.trunc' the amount of vertical
2611 space truncated by the most recently sprung vertical position trap,
2612 `.ne' the amount of vertical space needed in the last `ne' request
2613 that caused a vertical position trap to be sprung.
2615 The `cf' request now behaves sensibly in a diversion. If used in a
2616 diversion, it now arranges for the file to be copied to the output
2617 when the diversion is reread.
2619 There is a new request `trf' (transparent file) similar to `cf', but
2622 There is a new escape sequence `\Y[xxx]', roughly equivalent to
2623 `\X'\*[xxx]'', except that the contents of string or macro xxx are not
2624 interpreted, and xxx may contain newlines. This requires an output
2625 format extension; the drivers have been modified to understand this.
2626 Grops has also been modified to cope with newlines in the arguments to
2627 \X commands; grops has a new \X command mdef, which is like def except
2628 that it has a first argument giving the number of definitions.
2630 There is a new warning category `escape' which warns about unknown
2633 The `fp' request now takes an optional third argument giving the external
2636 The `\_' character is now automatically translated to `\(ul' as in troff.
2638 The environment variable `GROFF_HYPHEN' gives the name of the file
2639 containing the hyphenation patterns.
2641 There is a `\C'xxx'' escape sequence equivalent to `\[xxx]'.
2643 Characters ", ', ), ], *, \(dg are now initially transparent for the purposes
2644 of end of sentence recognition.
2646 There is an anti-recursion feature in the `char' request, so you can
2647 say `.char \(bu \s+2\(bu\s-2'.
2649 The limit on the number of font positions has been removed.
2650 Accordingly `\n[.fp]' never returns 0.
2652 The restriction on the number of numbered environments has been removed.
2654 There is a new escape sequence `\E' that makes it possible to
2655 guarantee that an escape sequence won't get interpreted in copy-mode.
2656 The `\R' escape sequence is accordingly now deprecated.
2661 Arguments of the form `X anything X' (in the `copy thru', `sh', `for',
2662 `if' and `define' constructs) can now be of the form `{ anything }'.
2664 If the `linethick' variable is negative (as it now is initially),
2665 lines are drawn with a thickness proportional to the current point
2668 The `rand' function now takes no arguments and returns a number between
2669 0 and 1. The old syntax is still supported.
2671 `^' can be used in expressions to indicate exponentiation.
2673 In the `for' construct the argument to the by clause can be prefixed
2674 by `*' to indicate that the increment is multiplicative.
2676 A bare expression may be used as an attribute. If the current
2677 direction is `dir', then an attribute `expr' is equivalent to
2680 There is a `sprintf' construct that allows numbers to be formatted and used
2681 wherever a quoted string can be used.
2683 The height of a text object without an explicit height attribute is
2684 the number of text strings associated with the object times the value
2685 of the `textht' variable.
2687 The maximum height and width of a picture is controlled by the
2688 `maxpswid' and `maxpsht' variables.
2693 Gtbl can now handle gracefully the situation where the `ce' request
2694 has been applied to a table.
2699 The `ifdef' primitive has been generalized.
2701 A tilde accent can be put underneath a box using `utilde'. This
2702 defined using a general `uaccent' primitive.
2707 There is a new PostScript font downloading scheme which handles font
2708 downloading for imported illustrations. Previously, the name of the
2709 file containing the font was given in the `x download' line in the
2710 groff font metric file. Now, there is a `download' file which says
2711 for each PostScript font name which file contains that font. Grops
2712 can also now handle inter-font dependencies, where one downloadable
2713 font depends on some other (possibly downloadable) font.
2715 The `T' font has been removed. The characters it used to provide are
2716 now provided by `char' definitions in tmac.ps. TSymbol.ps has also
2717 been removed, and the tweaks it provided are now provided by `char'
