Instance Method Details

- ({Symbol => String/Fixnum}) version

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
}

If a prerelease version of Haml is being used, the :string and :number fields will reflect the full version (e.g. "2.2.beta.1"), and the :teeny field will be -1. A :prerelease key will contain the name of the prerelease (e.g. "beta"), and a :prerelease_number key will contain the rerelease number. For example:

{
  :string => "3.0.beta.1",
  :number => "3.0.beta.1",
  :major => 3, :minor => 0, :teeny => -1,
  :prerelease => "beta",
  :prerelease_number => 1
}

Returns:

  • ({Symbol => String/Fixnum}) —

    The version hash
