# Gitaly note: JV: not sure what to make of this class. Why does it use
# the full disk path of the repository to look up attributes This is
# problematic in Gitaly, because Gitaly hides the full disk path to the
# repository from gitlab-ce.
module Gitlab
module Git
# Parses gitattributes at `$GIT_DIR/info/attributes`
#
# Unlike Rugged this parser only needs a single IO call (a call to `open`),
# vastly reducing the time spent in extracting attributes.
#
# This class _only_ supports parsing the attributes file located at
# `$GIT_DIR/info/attributes` as GitLab doesn't use any other files
# (`.gitattributes` is copied to this particular path).
#
# Basic usage:
#
# attributes = Gitlab::Git::InfoAttributes.new(some_repo.path)
#
# attributes.attributes('README.md') # => { "eol" => "lf }
class InfoAttributes
delegate :attributes, :patterns, to: :parser
# path - The path to the Git repository.
