Subject: [PATCH 4/5] builtin-merge: allow using a custom strategy
Date: Tue, 29 Jul 2008 17:25:02 +0200 [thread overview]
Message-ID: <722d66a5a897b694f374aa96bd58aff01a2a5932.1217344803.git.vmiklos@frugalware.org> (raw)
In-Reply-To: <5ad105819efb1c905bd01db3d08eb3422d283b3b.1217344803.git.vmiklos@frugalware.org>
In-Reply-To: <cover.1217344802.git.vmiklos@frugalware.org>
Allow using a custom strategy, as long as it's named git-merge-foo. The
error handling is now done using is_git_command(). The list of available
strategies is now shown by list_commands().
If an invalid strategy is supplied, like -s foobar, then git-merge would
list all git-merge-* commands. This is not perfect, since for example
git-merge-index is not a valid strategy.
These are removed from the output by scanning the list of main commands;
if the git-merge-foo command is listed in the all_strategy list, then
it's shown, otherwise excluded. This does not exclude commands somewhere
else in the PATH, where custom strategies are expected.
