git‐annex‐diffdriver − external git diff driver shim

git annex diffdriver −− cmd −−opts −−

This is an external git diff driver shim. Normally, when
using git diff with an external diff driver, the symlinks to
annexed files are not set up right, so the external diff
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 this, you will need to have installed some git
external diff driver command. This is not the regular diff
command; it takes a git−specific input. See git’s
documentation of GIT_EXTERNAL_DIFF and gitattributes(5)’s
documentation of external diff drivers.

     Configure git to use "git‐annex diffdriver −− cmd
params −−" as the external diff driver, where cmd is the
external diff driver you want it to run, 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 −−
