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.

-> String

Absolute path to the importing file.

-> IO [SassImport]

Imports.

Type of the function that acts like an importer.

You may return the empty list in order to tell libsass to handle the import by itself.

data SassImporter

Description of the importer.

Constructors

SassImporter

Fields

• importerPriority :: Double

  Priority of the importer.

• importerFunction :: SassImporterType

  Main function.

type SassHeaderType

Arguments

 = String

Absolute path to the file being processed.

-> IO [SassImport]

Imports.

Type of the function that acts like a header.

data SassHeader

Description of the header.

Constructors

SassHeader

Fields

• headerPriority :: Double

  Priority of the header.

• headerFunction :: SassHeaderType

  Main function.

makeSourceImport :: String -> SassImport

makeSourceImport s is equivalent to SassImport Nothing Nothing (Just s) Nothing.

makePathImport :: String -> String -> SassImport

makePathImport p b is equivalent to SassImport (Just p) (Just b) Nothing Nothing.
