module Haml
|
|
# Handles Haml version-reporting.
|
|
# Haml not only reports the standard three version numbers,
|
|
# but its Git revision hash as well,
|
|
# if it was installed from Git.
|
|
module Version
|
|
include Haml::Util
|
|
|
|
# Returns a hash representing the version of Haml.
|
|
# The `:major`, `:minor`, and `:teeny` keys have their respective numbers as Fixnums.
|
|
# The `:name` key has the name of the version.
|
|
# The `:string` key contains a human-readable string representation of the version.
|
|
# The `:number` key is the major, minor, and teeny keys separated by periods.
|
|
# If Haml is checked out from Git, the `:rev` key will have the revision hash.
|
|
# For example:
|
|
#
|
|
# {
|
|
# :string => "2.1.0.9616393",
|
|
# :rev => "9616393b8924ef36639c7e82aa88a51a24d16949",
|
|
# :number => "2.1.0",
|
|
# :major => 2, :minor => 1, :teeny => 0
|
|
# }
|
|
#
|
|
# @return [Hash<Symbol, String/Fixnum>] The version hash
