2016-02-25diff: activate diff.renames by defaultLibravatar Matthieu Moy1-1/+1
Rename detection is a very convenient feature, and new users shouldn't have to dig in the documentation to benefit from it. Potential objections to activating rename detection are that it sometimes fail, and it is sometimes slow. But rename detection is already activated by default in several cases like "git status" and "git merge", so activating diff.renames does not fundamentally change the situation. When the rename detection fails, it now fails consistently between "git diff" and "git status". This setting does not affect plumbing commands, hence well-written scripts will not be affected.

2016-02-25Documentation/diff-config: fix description of diff.renamesLibravatar Matthieu Moy1-3/+7
The description was misleading, since "set to any boolean value" include "set to false", and diff.renames=false does not enable basic detection, but actually disables it. Also, document that diff.renames only affects Porcelain. Signed-off-by: Matthieu Moy <Matthieu.Moy@imag.fr> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2013-09-11Improve documentation concerning the status.submodulesummary settingLibravatar Jens Lehmann1-1/+5
'git status' and 'git commit' can be told to also show the output of "git submodule summary" by setting the "status.submodulesummary" config option. But status and commit also honor the "diff.ignoreSubmodules" and the "submodule.<name>.ignore" settings, which then disable the summary partly or completely. This - and the fact that the last two settings do not affect the "git submodule" commands at all - is not well documented. Extend the documentation in those places where "status.submodulesummary", "diff.ignoreSubmodules" and "submodule.<name>.ignore" are described to better explain these dependencies.

Add diff.algorithm configuration so that the user does not type "diff --histogram". * mp/diff-algo-config: diff: Introduce --diff-algorithm command line option config: Introduce diff.algorithm variable git-completion.bash: Autocomplete --minimal and --histogram for git-diff

2013-01-16config: Introduce diff.algorithm variableLibravatar Michal Privoznik1-0/+17
Some users or projects prefer different algorithms over others, e.g. patience over myers or similar. However, specifying appropriate argument every time diff is to be used is impractical. Moreover, creating an alias doesn't play nicely with other tools based on diff (git-show for instance). Hence, a configuration variable which is able to set specific algorithm is needed. For now, these four values are accepted: 'myers' (which has the same effect as not setting the config variable at all), 'minimal', 'patience' and 'histogram'.

19299a8 (Documentation: Move diff.<driver>.* from config.txt to diff-config.txt, 2011-04-07) moved the diff configuration options to diff-config.txt, but forgot about diff.wordRegex, which was left behind in config.txt.

2012-09-30diff: diff.context configuration gives default to -ULibravatar Jeff Muizelaar1-0/+4
Introduce a configuration variable diff.context that tells Porcelain commands to use a non-default number of context lines instead of 3 (the default). With this variable, users do not have to keep repeating "git log -U8" from the command line; instead, it becomes sufficient to say "git config diff.context 8" just once.

2012-03-01diff --stat: add config option to limit graph widthLibravatar Zbigniew Jędrzejewski-Szmek1-0/+4
Config option diff.statGraphWidth=<width> is equivalent to --stat-graph-width=<width>, except that the config option is ignored by format-patch. For the graph-width limiting to be usable, it should happen 'automatically' once configured, hence the config option. Nevertheless, graph width limiting only makes sense when used on a wide terminal, so it should not influence the output of format-patch, which adheres to the 80-column standard.

2011-04-29New --dirstat=lines mode, doing dirstat analysis based on diffstatLibravatar Johan Herland1-0/+8
This patch adds an alternative implementation of show_dirstat(), called show_dirstat_by_line(), which uses the more expensive diffstat analysis (as opposed to show_dirstat()'s own (relatively inexpensive) analysis) to derive the numbers from which the --dirstat output is computed. The alternative implementation is controlled by the new "lines" parameter to the --dirstat option (or the diff.dirstat config variable). For binary files, the diffstat analysis counts bytes instead of lines, so to prevent binary files from dominating the dirstat results, the byte counts for binary files are divided by 64 before being compared to their textual/line-based counterparts. This is a stupid and ugly - but very cheap - heuristic. In linux-2.6.git, running the three different --dirstat modes: time git diff v2.6.20..v2.6.30 --dirstat=changes > /dev/null vs. time git diff v2.6.20..v2.6.30 --dirstat=lines > /dev/null vs. time git diff v2.6.20..v2.6.30 --dirstat=files > /dev/null yields the following average runtimes on my machine: - "changes" (default): ~6.0 s - "lines": ~9.6 s - "files": ~0.1 s So, as expected, there's a considerable performance hit (~60%) by going through the full diffstat analysis as compared to the default "changes" analysis (obviously, "files" is much faster than both). As such, the "lines" mode is probably only useful if you really need the --dirstat numbers to be consistent with the numbers returned from the other --*stat options. The patch also includes documentation and tests for the new dirstat mode.

2011-04-29Add config variable for specifying default --dirstat behaviorLibravatar Johan Herland1-0/+36
The new diff.dirstat config variable takes the same arguments as '--dirstat=<args>', and specifies the default arguments for --dirstat. The config is obviously overridden by --dirstat arguments passed on the command line. When not specified, the --dirstat defaults are 'changes,noncumulative,3'. The patch also adds several tests verifying the interaction between the diff.dirstat config variable, and the --dirstat command line option.

Although the gitattributes page contains comprehensive information about these configuration options, they should be included in the config documentation for completeness.
