Can someone provide guidance on how handle operator precedence and associativity with Polyparse?
Do you mean parsing something like "1 + 2 * 3" ? I don't think there's any real difference in using Polyparse vs Parsec for this, except for doing "p `orElse` q" rather than "try p <|> q".
Actually, I was looking for something equivalent to Text.ParserCombinators.Parsec.Expr.buildExpressionParser. I suppose I should learn how Parsec implements this under the hood.
There's nothing like that for PolyParse: it has a much smaller set of combinators than Parsec, which I for one prefer because I don't have to worry about behaviour of existing combinators being different than what I want/need (as it stands, I already use a custom version of bracket from polyparse). -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
