FParsec is fantastic. I have implemented a parser that supports a indentation based language in it. FParsec makes it very productive, and very fun.

Is published? I have tried to use FParsec before for the same kind of language and failed.

Its currently in a private bitbucket repo. I can give you the parser though, MIT licensed.

ParserUtils is where maybeIndented and indented are. They make indentation just work. There currently overzealous with backtracking though, makes errors kinda shit. Working on that at somepoint.

Ok, thanks.

But this not look more easy than just do it as TopDown Parser. But I don't know your language so it maybe have provided you with some benefits more than just lines of code?

Big benefit to me was being able to do it all with parser combinators, and without having to drop into another language like lex and yacc.

Parser combinators are top down parsers.
