+gitattributes - Defining attributes per path
SYNOPSIS
--------
Each line in `gitattributes` file is of form:
- pattern attr1 attr2 ...
+ pattern attr1 attr2 ...
That is, a pattern followed by an attributes list,
-separated by whitespaces. When the pattern matches the
-path in question, the attributes listed on the line are given to
-the path.
+separated by whitespaces. Leading and trailing whitespaces are
+ignored. Lines that begin with '#' are ignored. Patterns
+that begin with a double quote are quoted in C style.
+When the pattern matches the path in question, the attributes
+listed on the line are given to the path.
Each attribute can be in one of these states for a given path:
When more than one pattern matches the path, a later line
overrides an earlier line. This overriding is done per
-attribute. The rules how the pattern matches paths are the
-same as in `.gitignore` files; see linkgit:gitignore[5].
-Unlike `.gitignore`, negative patterns are forbidden.
+attribute.
-When deciding what attributes are assigned to a path, git
+The rules by which the pattern matches paths are the same as in
+`.gitignore` files (see linkgit:gitignore[5]), with a few exceptions:
+
+ - negative patterns are forbidden
+
+ - patterns that match a directory do not recursively match paths
+ inside that directory (so using the trailing-slash `path/` syntax is
+ pointless in an attributes file; use `path/**` instead)
+
+When deciding what attributes are assigned to a path, Git
consults `$GIT_DIR/info/attributes` file (which has the highest
precedence), `.gitattributes` file in the same directory as the
path in question, and its parent directories up to the toplevel of the
repositories (i.e., attributes of interest to all users) should go into
`.gitattributes` files. Attributes that should affect all repositories
for a single user should be placed in a file specified by the
-`core.attributesfile` configuration option (see linkgit:git-config[1]).

Its default value is $XDG_CONFIG_HOME/git/attributes. If $XDG_CONFIG_HOME
is either not set or empty, $HOME/.config/git/attributes is used instead.
Attributes for all users on a system should be placed in the
`$(prefix)/etc/gitattributes` file.

the name of the attribute prefixed with an exclamation point `!`.

+`working-tree-encoding`
+^^^^^^^^^^^^^^^^^^^^^^^
+
+Git recognizes files encoded in ASCII or one of its supersets (e.g.
+UTF-8, ISO-8859-1, ...) as text files. Files encoded in certain other
+encodings (e.g. UTF-16) are interpreted as binary and consequently
+built-in Git text processing tools (e.g. 'git diff') as well as most Git
+web front ends do not visualize the contents of these files by default.
+
+In these cases you can tell Git the encoding of a file in the working
+directory with the `working-tree-encoding` attribute. If a file with this
+attribute is added to Git, then Git reencodes the content from the
+specified encoding to UTF-8. Finally, Git stores the UTF-8 encoded
+content in its internal data structure (called "the index"). On checkout
+the content is reencoded back to the specified encoding.
+
+Please note that using the `working-tree-encoding` attribute may have a
+number of pitfalls:
+
+- Alternative Git implementations (e.g. JGit or libgit2) and older Git
+ versions (as of March 2018) do not support the `working-tree-encoding`
+ attribute. If you decide to use the `working-tree-encoding` attribute
+ in your repository, then it is strongly recommended to ensure that all
+ clients working with the repository support it.
++
+For example, Microsoft Visual Studio resources files (`*.rc`) or
+PowerShell script files (`*.ps1`) are sometimes encoded in UTF-16.
+If you declare `*.ps1` as files as UTF-16 and you add `foo.ps1` with
+a `working-tree-encoding` enabled Git client, then `foo.ps1` will be
+stored as UTF-8 internally. A client without `working-tree-encoding`
+support will checkout `foo.ps1` as UTF-8 encoded file. This will
+typically cause trouble for the users of this file.
++
+If a Git client that does not support the `working-tree-encoding`
+attribute adds a new file `bar.ps1`, then `bar.ps1` will be
+stored "as-is" internally (in this example probably as UTF-16).
+A client with `working-tree-encoding` support will interpret the
+internal contents as UTF-8 and try to convert it to UTF-16 on checkout.
+That operation will fail and cause an error.
+
+- Reencoding content to non-UTF encodings can cause errors as the
+ conversion might not be UTF-8 round trip safe. If you suspect your
+ encoding to not be round trip safe, then add it to
+ `core.checkRoundtripEncoding` to make Git check the round trip
+ encoding (see linkgit:git-config[1]). SHIFT-JIS (Japanese character
+ set) is known to have round trip issues with UTF-8 and is checked by
+ default.
+
+- Reencoding content requires resources that might slow down certain
+ Git operations (e.g 'git checkout' or 'git add').
+
+Use the `working-tree-encoding` attribute only if you cannot store a file
+in UTF-8 encoding and if you want Git to be able to process the content
+as text.
+
+As an example, use the following attributes if your '*.ps1' files are
+UTF-16 encoded with byte order mark (BOM) and you want Git to perform
+automatic line ending conversion based on your platform.
+
+------------------------
+*.ps1 text working-tree-encoding=UTF-16
+------------------------
+
+Use the following attributes if your '*.ps1' files are UTF-16 little
+endian encoded without BOM and you want Git to use Windows line endings
+in the working directory (use `UTF-16LE-BOM` instead of `UTF-16LE` if
+you want UTF-16 little endian with BOM).
+Please note, it is highly recommended to
+explicitly define the line endings with `eol` if the `working-tree-encoding`
+attribute is used to avoid ambiguity.
+
+------------------------
+*.ps1 text working-tree-encoding=UTF-16LE eol=CRLF
+------------------------
+
+You can get a list of all available encodings on your platform with the
+following command:
+
+------------------------
+iconv --list
+------------------------
+
+If you do not know the encoding of a file, then you can use the `file`
+command to guess the encoding:
+
+------------------------
+file foo.ps1
+------------------------
+
+
`ident`
^^^^^^^
-When the attribute `ident` is set for a path, git replaces
+When the attribute `ident` is set for a path, Git replaces
`$Id$` in the blob object with `$Id:`, followed by the
40-character hexadecimal blob object name, followed by a dollar
sign `$` upon checkout. Any byte sequence that begins with
fed the blob object from its standard input, and its standard
output is used to update the worktree file. Similarly, the
`clean` command is used to convert the contents of worktree file
-upon checkin.
+upon checkin. By default these commands process only a single
+blob and terminate. If a long running `process` filter is used
+in place of `clean` and/or `smudge` filters, then Git can process
+all blobs with a single filter command invocation for the entire
+life of a single Git command, for example `git add --all`. If a
+long running `process` filter is configured then it always takes
+precedence over a configured single blob filter. See section
+below for the description of the protocol used to communicate with
+a `process` filter.
One use of the content filtering is to massage the content into a shape
that is more convenient for the platform, filesystem, and the user to use.
Another use of the content filtering is to store the content that cannot
be directly used in the repository (e.g. a UUID that refers to the true
-content stored outside git, or an encrypted content) and turn it into a
+content stored outside Git, or an encrypted content) and turn it into a
usable form upon checkout (e.g. download the external content, or decrypt
the encrypted content).
into a usable content by setting the filter.<driver>.required configuration
variable to `true`.
+Note: Whenever the clean filter is changed, the repo should be renormalized:
+$ git add --renormalize .
+
For example, in .gitattributes, you would assign the `filter`
attribute for paths.
smudge = git-p4-filter --smudge %f
------------------------
+Note that "%f" is the name of the path that is being worked on. Depending
+on the version that is being filtered, the corresponding file on disk may
+not exist, or may have different contents. So, smudge and clean commands
+should not try to access the file on disk, but only act as filters on the
+content provided to them on standard input.
+
+Long Running Filter Process
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If the filter command (a string value) is defined via
+`filter.<driver>.process` then Git can process all blobs with a
+single filter invocation for the entire life of a single Git
+command. This is achieved by using the long-running process protocol
+(described in technical/long-running-process-protocol.txt).
+
+When Git encounters the first file that needs to be cleaned or smudged,
+it starts the filter and performs the handshake. In the handshake, the
+welcome message sent by Git is "git-filter-client", only version 2 is
+suppported, and the supported capabilities are "clean", "smudge", and
+"delay".
+
+Afterwards Git sends a list of "key=value" pairs terminated with
+a flush packet. The list will contain at least the filter command
+(based on the supported capabilities) and the pathname of the file
+to filter relative to the repository root. Right after the flush packet
+Git sends the content split in zero or more pkt-line packets and a
+flush packet to terminate content. Please note, that the filter
+must not send any response before it received the content and the
+final flush packet. Also note that the "value" of a "key=value" pair
+can contain the "=" character whereas the key would never contain
+that character.
+------------------------
+packet: git> command=smudge
+packet: git> pathname=path/testfile.dat
+packet: git> 0000
+packet: git> CONTENT
+packet: git> 0000
+------------------------
+
+The filter is expected to respond with a list of "key=value" pairs
+terminated with a flush packet. If the filter does not experience
+problems then the list must contain a "success" status. Right after
+these packets the filter is expected to send the content in zero
+or more pkt-line packets and a flush packet at the end. Finally, a
+second list of "key=value" pairs terminated with a flush packet
+is expected. The filter can change the status in the second list
+or keep the status as is with an empty list. Please note that the
+empty list must be terminated with a flush packet regardless.
+
+------------------------
+packet: git< status=success
+packet: git< 0000
+packet: git< SMUDGED_CONTENT
+packet: git< 0000
+packet: git< 0000 # empty list, keep "status=success" unchanged!
+------------------------
+
+If the result content is empty then the filter is expected to respond
+with a "success" status and a flush packet to signal the empty content.
+------------------------
+packet: git< status=success
+packet: git< 0000
+packet: git< 0000 # empty content!
+packet: git< 0000 # empty list, keep "status=success" unchanged!
+------------------------
+
+In case the filter cannot or does not want to process the content,
+it is expected to respond with an "error" status.
+------------------------
+packet: git< status=error
+packet: git< 0000
+------------------------
+
+If the filter experiences an error during processing, then it can
+send the status "error" after the content was (partially or
+completely) sent.
+------------------------
+packet: git< status=success
+packet: git< 0000
+packet: git< HALF_WRITTEN_ERRONEOUS_CONTENT
+packet: git< 0000
+packet: git< status=error
+packet: git< 0000
+------------------------
+
+In case the filter cannot or does not want to process the content
+as well as any future content for the lifetime of the Git process,
+then it is expected to respond with an "abort" status at any point
+in the protocol.
+------------------------
+packet: git< status=abort
+packet: git< 0000
+------------------------
+
+Git neither stops nor restarts the filter process in case the
+"error"/"abort" status is set. However, Git sets its exit code
+according to the `filter.<driver>.required` flag, mimicking the
+behavior of the `filter.<driver>.clean` / `filter.<driver>.smudge`
+mechanism.
+
+If the filter dies during the communication or does not adhere to
+the protocol then Git will stop the filter process and restart it
+with the next file that needs to be processed. Depending on the
+`filter.<driver>.required` flag Git will interpret that as error.
+
+Delay
+^^^^^
+
+If the filter supports the "delay" capability, then Git can send the
+flag "can-delay" after the filter command and pathname. This flag
+denotes that the filter can delay filtering the current blob (e.g. to
+compensate network latencies) by responding with no content but with
+the status "delayed" and a flush packet.
+------------------------
+packet: git> command=smudge
+packet: git> pathname=path/testfile.dat
+packet: git> can-delay=1
+packet: git> 0000
+packet: git> CONTENT
+packet: git> 0000
+packet: git< status=delayed
+packet: git< 0000
+------------------------
+
+If the filter supports the "delay" capability then it must support the
+"list_available_blobs" command. If Git sends this command, then the
+filter is expected to return a list of pathnames representing blobs
+that have been delayed earlier and are now available.
+The list must be terminated with a flush packet followed
+by a "success" status that is also terminated with a flush packet. If
+no blobs for the delayed paths are available, yet, then the filter is
+expected to block the response until at least one blob becomes
+available. The filter can tell Git that it has no more delayed blobs
+by sending an empty list. As soon as the filter responds with an empty
+list, Git stops asking. All blobs that Git has not received at this
+point are considered missing and will result in an error.
+
+------------------------
+packet: git> command=list_available_blobs
+packet: git> 0000
+packet: git< pathname=path/testfile.dat
+packet: git< pathname=path/otherfile.dat
+packet: git< 0000
+packet: git< status=success
+packet: git< 0000
+------------------------
+
+After Git received the pathnames, it will request the corresponding
+blobs again. These requests contain a pathname and an empty content
+section. The filter is expected to respond with the smudged content
+in the usual way as explained above.
+------------------------
+packet: git> command=smudge
+packet: git> pathname=path/testfile.dat
+packet: git> 0000
+packet: git> 0000 # empty content!
+packet: git< status=success
+packet: git< 0000
+packet: git< SMUDGED_CONTENT
+packet: git< 0000
+packet: git< 0000 # empty list, keep "status=success" unchanged!
+------------------------
+
+Example
+^^^^^^^
+
+A long running filter demo implementation can be found in
+`contrib/long-running-filter/example.pl` located in the Git
+core repository. If you develop your own long running filter
+process then the `GIT_TRACE_PACKET` environment variables can be
+very helpful for debugging (see linkgit:git[1]).
+
+Please note that you cannot use an existing `filter.<driver>.clean`
+or `filter.<driver>.smudge` command with `filter.<driver>.process`
+because the former two use a different inter process communication
+protocol than the latter one.

If you have these three `gitattributes` file:
the attributes given to path `t/abc` are computed as follows:
