Generalize and libify index_is_dirty() to index_differs_from(...)

2009-02-11T06:25:39Z

index_is_dirty() in builtin-revert.c checks if the index is dirty. This patch generalizes this function to check if the index differs from a revision, i.e. the former index_is_dirty() behavior can now be achieved by index_differs_from("HEAD", 0). The second argument "diff_flags" allows to set further diff option flags like DIFF_OPT_IGNORE_SUBMODULES. See DIFF_OPT_* macros in diff.h for a list. index_differs_from() seems to be useful for more than builtin-revert.c, so it is moved into diff-lib.c and also used in builtin-commit.c. Yet to mention: - "rev.abbrev = 0;" can be safely removed. This has no impact on performance or functioning of neither setup_revisions() nor run_diff_index(). - rev.pending.objects is free()d because this fixes a leak. (Also see 295dd2ad "Fix memory leak in traverse_commit_list") Mentored-by: Daniel Barkalow Mentored-by: Christian Couder Signed-off-by: Stephan Beyer Signed-off-by: Junio C Hamano

color-words: take an optional regular expression describing words

2009-01-17T18:43:08Z

In some applications, words are not delimited by white space. To allow for that, you can specify a regular expression describing what makes a word with git diff --color-words='[A-Za-z0-9]+' Note that words cannot contain newline characters. As suggested by Thomas Rast, the words are the exact matches of the regular expression. Note that a regular expression beginning with a '^' will match only a word at the beginning of the hunk, not a word at the beginning of a line, and is probably not what you want. This commit contains a quoting fix by Thomas Rast. Signed-off-by: Johannes Schindelin Signed-off-by: Junio C Hamano

diff: add option to show context between close hunks

2008-12-29T09:05:21Z

Merge two hunks if there is only the specified number of otherwise unshown context between them. For --inter-hunk-context=1, the resulting patch has the same number of lines but shows uninterrupted context instead of a context header line in between. Patches generated with this option are easier to read but are also more likely to conflict if the file to be patched contains other changes. This patch keeps the default for this option at 0. It is intended to just make the feature available in order to see its advantages and downsides. Signed-off-by: Rene Scharfe Signed-off-by: Junio C Hamano

userdiff: require explicitly allowing textconv

2008-10-26T21:09:48Z

Diffs that have been produced with textconv almost certainly cannot be applied, so we want to be careful not to generate them in things like format-patch. This introduces a new diff options, ALLOW_TEXTCONV, which controls this behavior. It is off by default, but is explicitly turned on for the "log" family of commands, as well as the "diff" porcelain (but not diff-* plumbing). Because both text conversion and external diffing are controlled by these diff options, we can get rid of the "plumbing versus porcelain" distinction when reading the config. This was an attempt to control the same thing, but suffered from being too coarse-grained. Signed-off-by: Jeff King Signed-off-by: Junio C Hamano

diff --dirstat-by-file: count changed files, not lines

2008-09-05T21:04:26Z

This new option --dirstat-by-file is the same as --dirstat, but it counts "impacted files" instead of "impacted lines" (lines that are added or removed). Signed-off-by: Heikki Orsila Signed-off-by: Junio C Hamano

diff --cumulative is a sub-option of --dirstat

2008-09-04T05:37:03Z

The option used to be implemented as if it is a totally independent one, but "git diff --cumulative" would not mean anything without "--dirstat". This makes --cumulative imply --dirstat. Signed-off-by: Junio C Hamano

diff: vary default prefix depending on what are compared

2008-08-31T03:53:24Z

With a new configuration "diff.mnemonicprefix", "git diff" shows the differences between various combinations of preimage and postimage trees with prefixes different from the standard "a/" and "b/". Hopefully this will make the distinction stand out for some people. "git diff" compares the (i)ndex and the (w)ork tree; "git diff HEAD" compares a (c)ommit and the (w)ork tree; "git diff --cached" compares a (c)ommit and the (i)ndex; "git-diff HEAD:file1 file2" compares an (o)bject and a (w)ork tree entity; "git diff --no-index a b" compares two non-git things (1) and (2). Because these mnemonics now have meanings, they are swapped when reverse diff is in effect and this feature is enabled. Signed-off-by: Junio C Hamano
