Instance Method Details
#version ⇒ {Symbol => String/Fixnum}
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
}
