Text.Sass.Functions

Provides support for user-defined functions, importers and headers.

Functions

type SassFunctionType

Arguments

 = SassValue

Arguments of the function (SassList).

-> IO SassValue

Result of the computation.

Type of the function that may be used in sass source.

data SassFunction

Description of the function that may be used in sass source.

Constructors

SassFunction

Fields

• funcSignature :: String

  Signature of the function, parsable by libsass.

• funcComputation :: SassFunctionType

  Main function.

Imports and headers

data SassImport

Represents a sass import - a sass content with additional metadata.

Even though this ADT has four fields, you may just provide either importPath and importBase and leave loading to the library, or provide importSource and do not provide importPath nor importBase. Nevertheless, you are free to provide all of the fields.

Constructors

SassImport

Fields

• importPath :: Maybe FilePath

  Path to the import, relative to base.

• importBase :: Maybe FilePath

  Base path.

• importSource :: Maybe String

  Import's source.

• importSourceMap :: Maybe String

  Source map of the import.

type SassImporterType

Arguments

 = String

Path to the import that needs to be loaded or file that is being processed when used as a header.

-> IO [SassImport]

Imports.

Type of the function that acts like importer/header.

You may return empty list in order to tell libsass to handle the import by itself or not insert any header.

data SassImporter

Description of the importer.

Constructors

SassImporter

Fields

• importerPriority :: Double

  Priority of the importer.

• importerFunction :: SassImporterType

  Main function.

makeSourceImport :: String -> SassImport
