# A class for running commands in a git directory
#
# It's faster to check if we're already in that directory instead
# of having to `cd` into each time. https://twitter.com/schneems/status/1305196730170961920
#
# Example:
#
# in_git_path = InGitPath.new(`bundle info heapy --path`.strip)
# in_git_path.checkout!("f0f92b06156f2274021aa42f15326da041ee9009")
# in_git_path.short_sha # => "f0f92b0"
class Git::InPath
attr_reader :path
def initialize(path)
@path = path
end
