# NAME

git-annex diffdriver - external git diff driver shim

# SYNOPSIS

git annex diffdriver `-- cmd --opts --`

# DESCRIPTION

This is an external git diff driver shim. Normally, when using `git diff`
with an external git driver, the symlinks to annexed files are not set up
right, so the external git driver cannot read them in order to perform
smart diffing of their contents. This command works around the problem,
by passing the fixed up files to the real external diff driver.

To use, just configure git to use "git-annex diffdriver -- cmd params --"
as the external diff command, where cmd is the real external diff
command you want to use, and params are any extra parameters to pass
to it. Note the trailing "--", which is required.

For example, set `GIT_EXTERNAL_DIFF=git-annex diffdriver -- j-c-diff --`
