containers

A modular, clean and powerful extension of the OCaml standard library
IN THIS PACKAGE
Module CCParse . Infix
val (>|=) : 'a t -> ( 'a -> 'b ) -> 'b t

Alias to map. p >|= f parses an item x using p, and returns f x.

val (>>=) : 'a t -> ( 'a -> 'b t ) -> 'b t

Alias to bind. p >>= f results in a new parser which behaves as p then, in case of success, applies f to the result.

val (<*>) : ( 'a -> 'b ) t -> 'a t -> 'b t

Applicative.

val (<*) : 'a t -> _ t -> 'a t

a <* b parses a into x, parses b and ignores its result, and returns x.

val (*>) : _ t -> 'a t -> 'a t

a *> b parses a, then parses b into x, and returns x. The result of a is ignored.

val (<|>) : 'a t -> 'a t -> 'a t

Alias to or_.

a <|> b tries to parse a, and if a fails without consuming any input, backtracks and tries to parse b, otherwise it fails as a.

val (<?>) : 'a t -> string -> 'a t

a <?> msg behaves like a, but if a fails, a <?> msg fails with msg instead. Useful as the last choice in a series of <|>. For example: a <|> b <|> c <?> "expected one of a, b, c".

val (|||) : 'a t -> 'b t -> ('a * 'b) t

Alias to both. a ||| b parses a, then b, then returns the pair of their results.
