Description

Synopsis

Context and elements

data Ctxt Source

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

Constructors

Ctxt

Fields

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

emptyCtxt :: Ctxt Source

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

data Element a Source

An element holds a value along with the user-defined object’s name (if exists), the associated groups and the used material. Those values can be used to sort the data per object or per group and to lookup materials.

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.
