Subject: [PATCH v3 5/5] stash: teach 'push' (and 'create') to honor pathspec
Date: Sun,  5 Feb 2017 20:26:42 +0000	[thread overview]
Message-ID: <20170205202642.14216-6-t.gummerer@gmail.com> (raw)
In-Reply-To: <20170205202642.14216-1-t.gummerer@gmail.com>

While working on a repository, it's often helpful to stash the changes
of a single or multiple files, and leave others alone.  Unfortunately
git currently offers no such option.  git stash -p can be used to work
around this, but it's often impractical when there are a lot of changes
over multiple files.

Allow 'git stash push' to take pathspec to specify which paths to stash.

 	only <message> does not trigger this action to prevent a misspelled
 	subcommand from making an unwanted stash.
 +
+When pathspec is given to 'git stash push', the new stash records the
+modified states only for the files that match the pathspec.  The index
+entries and working tree files are then rolled back to the state in
+HEAD only for these files, too, leaving files that do not match the
+pathspec intact.
++
 If the `--keep-index` option is used, all changes already added to the
 index are left intact.
