Better Git diffs

[hauleth]

In Git 2.25 there comes native support for Elixir definitions. That will
make git diff --function-context work properly. Additionally it makes
diff headers to contain name of enclosing function.

I hope that this will work in GitHub diffs as well.

Would it make sense to generate a .gitattributes file when generating a new project, similar to .gitignore?

[hauleth]

@michalmuskala I would rather document such thing and encourage people to add it to their own global Git configuration:

$ mkdir -p ~/.config/git
$ printf '*.ex diff=elixir\n*.exs diff=elixir\n' >> ~/.config/git/attributes

[michalmuskala]

Makes sense. Given I know nothing about how git attributes work - why wouldn't that be a default now that git has this support? Is there some conflict on the extensions?

[hauleth]

Because Git do not support default attributes for any files at all. It would be big change in Git to provide defaults and I do not have time to go through that right now.

TL;DR there is no "default" attributes in Git, everything uses the same and user can define them on their own

[michalmuskala]

Makes sense. Thank you for explaining.
