This was added long ago as part of the userdiff refactoring for textconv, as internally it made the code simpler and cleaner.

2010-12-27diff: funcname and word patterns for perlLibravatar Jonathan Nieder1-0/+2
The default function name discovery already works quite well for Perl code... with the exception of here-documents (or rather their ending). sub foo { print <<END here-document END return 1; } The default funcname pattern treats the unindented END line as a function declaration and puts it in the @@ line of diff and "grep --show-function" output. With a little knowledge of perl syntax, we can do better. You can try it out by adding "*.perl diff=perl" to the gitattributes file.

2010-12-22convert filter: supply path to external driverLibravatar Pete Wyckoff1-0/+10
Filtering to support keyword expansion may need the name of the file being filtered. In particular, to support p4 keywords like $File: //depot/product/dir/script.sh $ the smudge filter needs to know the name of the file it is smudging. Allow "%f" in the custom filter command line specified in the configuration. This will be substituted by the filename inside a single-quote pair to be passed to the shell.

2010-12-01Make the tab width used for whitespace checks configurableLibravatar Johannes Sixt1-2/+4
A new whitespace "rule" is added that sets the tab width to use for whitespace checks and fix-ups and replaces the hard-coded constant 8. Since the setting is part of the rules, it can be set per file using .gitattributes. The new configuration is backwards compatible because older git versions simply ignore unknown whitespace rules.

2010-09-10userdiff.c: add builtin fortran regex patternsLibravatar Brandon Casey1-0/+2
This adds fortran xfuncname and wordRegex patterns to the list of builtin patterns. The intention is for the patterns to be appropriate for all versions of fortran including 77, 90, 95. The patterns can be enabled by adding the diff=fortran attribute to the .gitattributes file for the desired file glob. This also adds a new macro named IPATTERN which is just like the PATTERNS macro except it sets the REG_ICASE flag so that case will be ignored. The test code in t4018 and the docs were updated as appropriate. Signed-off-by: Brandon Casey <casey@nrlssc.navy.mil> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2010-07-02Avoid conflicts when merging branches with mixed normalizationLibravatar Eyvind Bernhardsen1-0/+34
Currently, merging across changes in line ending normalization is painful since files containing CRLF will conflict with normalized files, even if the only difference between the two versions is the line endings. Additionally, any "real" merge conflicts that exist are obscured because every line in the file has a conflict. Assume you start out with a repo that has a lot of text files with CRLF checked in (A): o---C / \ A---B---D B: Add "* text=auto" to .gitattributes and normalize all files to LF-only C: Modify some of the text files D: Try to merge C You will get a ridiculous number of LF/CRLF conflicts when trying to merge C into D, since the repository contents for C are "wrong" wrt the new .gitattributes file. Fix ll-merge so that the "base", "theirs" and "ours" stages are passed through convert_to_worktree() and convert_to_git() before a three-way merge. This ensures that all three stages are normalized in the same way, removing from consideration differences that are only due to normalization. This feature is optional for now since it changes a low-level mechanism and is not necessary for the majority of users. The "merge.renormalize" config variable enables it.

2010-06-06Add "core.eol" config variableLibravatar Eyvind Bernhardsen1-13/+15
Introduce a new configuration variable, "core.eol", that allows the user to set which line endings to use for end-of-line-normalized files in the working directory. It defaults to "native", which means CRLF on Windows and LF everywhere else. Note that "core.autocrlf" overrides core.eol. This means that [core] autocrlf = true puts CRLFs in the working directory even if core.eol is set to "lf".

2010-05-19Add per-repository eol normalizationLibravatar Eyvind Bernhardsen1-25/+113
Change the semantics of the "crlf" attribute so that it enables end-of-line normalization when it is set, regardless of "core.autocrlf". Add a new setting for "crlf": "auto", which enables end-of-line conversion but does not override the automatic text file detection. Add a new attribute "eol" with possible values "crlf" and "lf". When set, this attribute enables normalization and forces git to use CRLF or LF line endings in the working directory, respectively. The line ending style to be used for normalized text files in the working directory is set using "core.autocrlf". When it is set to "true", CRLFs are used in the working directory; when set to "input" or "false", LFs are used.

2010-04-14diff: add --word-diff option that generalizes --color-wordsLibravatar Thomas Rast1-1/+1
This teaches the --color-words engine a more general interface that supports two new modes: * --word-diff=plain, inspired by the 'wdiff' utility (most similar to 'wdiff -n <old> <new>'): uses delimiters [-removed-] and {+added+} * --word-diff=porcelain, which generates an ad-hoc machine readable format: - each diff unit is prefixed by [-+ ] and terminated by newline as in unified diff - newlines in the input are output as a line consisting only of a tilde '~' Both of these formats still support color if it is enabled, using it to highlight the differences. --color-words becomes a synonym for --word-diff=color, which is the color-only format. Also adds some compatibility/convenience options. Thanks to Junio C Hamano and Miles Bader for good ideas.

2010-04-02diff: cache textconv outputLibravatar Jeff King1-0/+20
Running a textconv filter can take a long time. It's particularly bad for a large file which needs to be spooled to disk, but even for small files, the fork+exec overhead can add up for something like "git log -p". This patch uses the notes-cache mechanism to keep a fast cache of textconv output. Caches are stored in refs/notes/textconv/$x, where $x is the userdiff driver defined in gitattributes. Caching is enabled only if diff.$x.cachetextconv is true. In my test repo, on a commit with 45 jpg and avi files changed and a textconv to show their exif tags: [before] $ time git show >/dev/null real 0m13.724s user 0m12.057s sys 0m1.624s [after, first run] $ git config diff.mfo.cachetextconv true $ time git show >/dev/null real 0m14.252s user 0m12.197s sys 0m1.800s [after, subsequent runs] $ time git show >/dev/null real 0m0.352s user 0m0.148s sys 0m0.200s So for a slight (3.8%) cost on the first run, we achieve an almost 40x speed up on subsequent runs.

2010-01-10Documentation: spell 'git cmd' without dash throughoutLibravatar Thomas Rast1-6/+6
The documentation was quite inconsistent when spelling 'git cmd' if it only refers to the program, not to some specific invocation syntax: both 'git-cmd' and 'git cmd' spellings exist. The current trend goes towards dashless forms, and there is precedent in 647ac70 (git-svn.txt: stop using dash-form of commands., 2009-07-07) to actively eliminate the dashed variants. Replace 'git-cmd' with 'git cmd' throughout, except where git-shell, git-cvsserver, git-upload-pack, git-receive-pack, and git-upload-archive are concerned, because those really live in the $PATH.

Most of the docs and printouts refer to "commands" when discussing what the end users call via the "git" top-level program. We should refer them as "git programs" when we discuss the fact that the commands are implemented as separate programs, but in other contexts, it is better to use the term "git commands" consistently.

2009-04-17doc/gitattributes: clarify location of config textLibravatar Jeff King1-3/+6
The gitattributes documentation has a section on the "diff" attribute, with subsections for each of the things you might want to configure in your diff config section (external diff, hunk headers, etc). The first such subsection specifically notes that the definition of the diff driver should go into $GIT_DIR/config, but subsequent sections do not. This location is implied if you are reading the documentation sequentially, but it is not uncommon for a new user to jump to (or be referred to) a specific section. For a new user who does not know git well enough to recognize the config syntax, it is not clear that those directives don't also go into the gitattributes file. This patch just mentions the config file in each subsection, similar to the way it is mentioned in the first.
