Description

Synopsis

Context and elements

The lexer context. The result of lexing a stream of tokens is this exact type.

Constructors

Fields

ctxtName :: Maybe Text: Name of the object. Nothing means that the object is not user-defined.
ctxtLocations :: DList Location: Locations.
ctxtTexCoords :: DList TexCoord: Texture coordinates.
ctxtNormals :: DList Normal: Normals.
ctxtPoints :: DList (Element Point): Points.
ctxtLines :: DList (Element Line): Lines.
ctxtFaces :: DList (Element Face): Faces.
ctxtCurrentObject :: Maybe Text: Current object.
ctxtCurrentGroups :: [Text]: Current groups.
ctxtCurrentMtl :: Maybe Text: Current material.
ctxtMtlLibs :: DList Text: Material libraries.

Instances

Eq Ctxt Source
Show Ctxt Source

The empty Ctxt. Such a context exists at the beginning of the token stream and gets altered as we consume tokens.

An element holds a value along with the user-defined object’s name (if exists), the associated groups and the used material.

Constructors

Element
Fields elObject :: Maybe Text elGroups :: [Text] elMtl :: Maybe Text elValue :: a

Instances

Eq a => Eq (Element a) Source
Show a => Show (Element a) Source

lexer :: TokenStream -> Ctxt Source

The lexer function, consuming tokens and yielding a Ctxt.
