# File lib/lolcommits/cli/fatals.rb, line 66 def self.die_if_not_git_repo! debug 'Checking for valid git repo' Git.open('.') # FIXME: should be extracted to GitInfo class rescue ArgumentError # ruby-git throws an argument error if path isnt for a valid git repo. fatal "Erm? Can't do that since we're not in a valid git repository!" exit 1 end
