mergetool: fallback to tool when guitool unavailable In git-difftool, if the tool is called with --gui but `diff.guitool` is not set, it falls back to `diff.tool`. Make git-mergetool also fallback from `merge.guitool` to `merge.tool` if the former is undefined. If git-difftool, when called with `--gui`, were to use `get_configured_mergetool` in a future patch, it would also get the fallback behavior in the following precedence: 1. diff.guitool 2. merge.guitool 3. diff.tool 4. merge.tool The behavior for when difftool or mergetool are called without `--gui` should be identical with or without this patch. Note that the search loop could be written as sections="merge" keys="tool" if diff_mode then sections="diff $sections" fi if gui_mode then keys="guitool $keys" fi merge_tool=$( IFS=' ' for key in $keys do for section in $sections do selected=$(git config $section.$key) if test -n "$selected" then echo "$selected" return fi done done) which would make adding a mode in the future much easier. However, adding a new mode will likely never happen as it is highly discouraged so, as a result, it is written in its current form so that it is more readable for future readers.

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-.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://public-inbox.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):
