Documentation

initState :: HlState Source #

alexScanToken :: (AlexState HlState, AlexInput) -> Maybe (Tok Token, (AlexState HlState, AlexInput)) Source #

Scan one token. Return (maybe) a token and a new state.

tokenToStyle :: Token -> UIStyle -> Style Source #

Takes a Token and returns a style to be used for that type of token.

TODO: The elem check is potentially unnecessarily slow. We could split the Const constructor into two different ones, one for builtins and one for others.

type TT = Tok Token Source #

data Token Source #

The different tokens.

data Reserved Source #

The constructors for Reserved have an apostrophe as a suffix because Default is already used. Also note that Undefined' is not intended as some sort of "backup" reserved word for things we don't care about -- it really means the "undefined" built-in in JavaScript.

Show Reserved Source #

Eq Reserved Source #

data Operator Source #

The constructors for Operator have an apostrophe as a suffix because e.g. LT is already used by Prelude.

Instances

Eq Operator Source #

type HlState = Int Source #

HlState is 0 when outside of a multi-line comment and -1 when inside one.

prefixOperators :: [Operator] Source #

Prefix operators. NOTE: Add' is also a valid prefix operator, but since it's completely useless in the real world, we don't care about it here. Doing this makes parsing much, much easier.

infixOperators :: [Operator] Source #

Infix operators.

postfixOperators :: [Operator] Source #

Postfix operators.
