Method: Overcommit::Utils.repo_root

Defined in:
lib/overcommit/utils.rb

.repo_root ⇒ String

Returns an absolute path to the root of the repository.

We do this ourselves rather than call ‘git rev-parse –show-toplevel` to solve an issue where the .git directory might not actually be valid in tests.

Returns:

  • (String)
