git‐annex‐smudge − git filter driver for git‐annex


git annex smudge [−−clean] file

     git annex smudge −−update


This command lets git‐annex be used as a git filter driver
which lets annexed files in the git repository to be
unlocked, instead of being symlinks, and lets git add store
files in the annex.

     When adding a file with git add, the annex.largefiles
config is consulted to decide if a given file should be
added to git as−is, or if its content are large enough to
need to use git‐annex.  The annex.gitaddtoannex setting
overrides that; setting it to false prevents git add from
adding files to the annex.

     However, if git‐annex can tell that a file was annexed
before, it will still be added to the annex even when those
configs would normally prevent it. Two examples of this are
adding a modified version of an annexed file, and moving an
annexed file to a new filename and adding that.

     The git configuration to use this command as a filter
driver is as follows.  This is normally set up for you by
git‐annex init, so you should not need to configure it
manually.

      [filter "annex"]
         smudge = git‐annex smudge %f
         clean = git‐annex smudge −−clean %f

     To make git use that filter driver, it needs to be
configured in the .gitattributes file or in
.git/info/attributes. The latter is normally configured when
a repository is initialized, with the following contents:

      * filter=annex
 .* !filter

     The smudge filter does not provide git with the content
of annexed files, because that would be slow and triggers
memory leaks in git. Instead, it records which worktree
files need to be updated, and git annex smudge −−update
later updates the work tree to contain the content. That is
run by several git hooks, including post−checkout and
post−merge. However, a few git commands, notably git stash
and git cherry−pick, do not run any hooks, so after using
those commands you can manually run git annex smudge
−−update to update the working tree.
