NAME

6       git-annex-diffdriver - external git diff driver shim
7

SYNOPSIS

9       git annex diffdriver -- cmd --opts --
10

DESCRIPTION

12       This is an external git diff driver shim. Normally, when using git diff
13       with an external diff driver, it will not see the contents  of  annexed
14       files,  since git passes to it the git-annex symlinks or pointer files.
15       This command works around the problem, by  running  the  real  external
16       diff driver, and passing it the paths to the annexed content.
17
18       To  use  this,  you  will need to have installed some git external diff
19       driver command. This is not  the  regular  diff  command;  it  takes  a
20       git-specific  input.  See  git's documentation of GIT_EXTERNAL_DIFF and
21       gitattributes(5)'s documentation of external diff drivers.
22
23       Configure git to use "git-annex diffdriver -- cmd params --" as the ex‐
24       ternal  diff  driver, where cmd is the external diff driver you want it
25       to run, and params are any extra parameters to pass  to  it.  Note  the
26       trailing "--", which is required.
27
28       For example, set GIT_EXTERNAL_DIFF=git-annex diffdriver -- j-c-diff --
29

OPTIONS

31       Normally "--" followed by the diff driver command, its options, and an‐
32       other "--"
33
34       Also the git-annex-common-options(1) can be used.
