6 git-annex-diffdriver - external git diff driver shim

9 git annex diffdriver -- cmd --opts --
10
12 This is an external git diff driver shim. Normally, when using git diff
13 with an external diff driver, the symlinks to annexed files are not set
14 up right, so the external diff driver cannot read them in order to per‐
15 form smart diffing of their contents. This command works around the
16 problem, by passing the fixed up files to the real external diff
17 driver.
18
19 To use this, you will need to have installed some git external diff
20 driver command. This is not the regular diff command; it takes a
21 git-specific input. See git's documentation of GIT_EXTERNAL_DIFF and
22 gitattributes(5)'s documentation of external diff drivers.
23
24 Configure git to use "git-annex diffdriver -- cmd params --" as the
25 external diff driver, where cmd is the external diff driver you want it
26 to run, and params are any extra parameters to pass to it. Note the
27 trailing "--", which is required.
28
29 For example, set GIT_EXTERNAL_DIFF=git-annex diffdriver -- j-c-diff --
