Using gron as an external git diff driver

.gitattributes

*.json diff=gron

.gitconfig

[diff "gron"]
    textconv=gron --no-sort

[core]
    # or omit this and put the attributes file
    # in ~/.config/git/attributes instead
    attributesfile=~/.gitattributes

This allows you to use gron as an external diff tool for git.

You just need both of these files in your $HOME, plus gron of course 😄

Usage:

git show HEAD:test.json
{
  "foo": "bar"
}

cat test.json
{
  "foo": "bar",
  "baz": "quux"
}

git diff test.json
diff --git test.json test.json
index c8c4105..3fe4371 100644
--- test.json
+++ test.json
@@ -1,2 +1,3 @@
 json = {};
 json.foo = "bar";
+json.baz = "quux";
