Now that the Perl version produces the same output as the built-in version (mostly fixing bugs in the latter), let's add a regression test to verify that it stays this way. Note that we only `grep` for the colored error message instead of verifying that the entire `stderr` consists of just this one line: when running the test script using the `-x` option to trace the commands, the sub-shell in `force_color` causes those commands to be traced into `err.raw` (unless running in Bash where we set the `BASH_XTRACEFD` variable to avoid that). Also note that the color reset in the `<BLUE>+<RESET><BLUE>new<RESET>` line might look funny and unnecessary, as the corresponding `old` line does not reset the color after the diff marker only to turn the color back on right away. However, this is a (necessary) side effect of the white-space check: in `emit_line_ws_markup()`, we first emit the diff marker via `emit_line_0()` and then the rest of the line via `ws_check_emit()`. To leave them somewhat decoupled, the color has to be reset after the diff marker to allow for the rest of the line to start with another color (or inverted, in case of white-space issues). Finally, we have to simulate hunk editing: the `git add -p` command cannot rely on the internal diff machinery for coloring after letting the user edit a hunk; It has to "re-color" the edited hunk. This is the primary reason why that command is interested in the exact values of the `color.diff.*` settings in the first place. To test this re-coloring, we therefore have to pretend to edit a hunk and then show that hunk in the regression test.

Git - fast, scalable, distributed revision control system
Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.
Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.
See Documentation/gittutorial.txt to get started, then see
Documentation/giteveryday.txt for a useful minimum set of commands, and
Documentation/git-<commandname>.txt for documentation of each command.
If git has been correctly installed, then the tutorial can also be
read with man gittutorial or git help tutorial, and the
documentation of each command with man git-<commandname> or git help <commandname>.
CVS users may also want to read Documentation/gitcvs-migration.txt
(man gitcvs-migration or git help cvs-migration if git is
installed).
The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission). To subscribe to the list, send an email with just "subscribe git" in the body to majordomo@vger.kernel.org. The mailing list archives are available at https://lore.kernel.org/git/, http://marc.info/?l=git and other archival sites.
Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.
The maintainer frequently sends the "What's cooking" reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.
The name "git" was given by Linus Torvalds when he wrote the very first version. He described the tool as "the stupid content tracker" and the name as (depending on your mood):
- random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant.
- stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang.
- "global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room.
- "goddamn idiotic truckload of sh*t": when it breaks
