NAME¶git-annex-smudge - git filter driver for git-annex
SYNOPSIS¶git annex smudge [--clean] file
git annex smudge --update
DESCRIPTION¶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.
- The git-annex-common-options(1) can be used.
