+# git fake bare repositories have a detached workspace. One potential
+# application is storing dotfiles in git, keeping them checked out in
+# one $HOME, but checked into different git repositories. This file adds
# support for them, separate from the normal git support.
# To make mr use this file, add a line like this inside the [DEFAULT]
# section of your ~/.mrconfig
#include = cat /path/to/mrconfig.git-fake-bare
+# And an example repo using it would look something like:
+#[.dotfiles]
+#lib = git_fake_bare_worktree $HOME
+#checkout = git_fake_bare_checkout git://... .dotfiles
+
+lib =
+ # called to tell git where the worktree is
+ git_fake_bare_worktree() {
+ GIT_WORK_TREE="$1"; export GIT_WORK_TREE

+ # git doesn't have an easy way to check out such a repo, so
+ # do it by hand
