Hi everybody, I am using the uu-parsinglib to parse a structured language and map the results to some proper data structures. Thanks to Prof Doaitse Swierstra (and other authors if any), it is fun to write a parser using this library. I've been sending private mails to Doaitse about my questions, who kindly gives nice replies everytime. But this time I thought I can ask my question to the community, and give everyone the chance to benefit from the answers. [After the intro, here comes my real question] I am trying to capture the following pattern. pKeyword_Int = ( \ _ _ _ -> "int" ) <$> pSym 'i' <*> pSym 'n' <*> pSym 't' pKeyword_Float = ( \ _ _ _ _ _ -> "float" ) <$> pSym 'f' <*> pSym 'l' <*> pSym 'o' <*> pSym 'a' <*> pSym 't' As you can see there is an obvious pattern if you try to capture a "keyword". If there were a function called pKeyword taking a string as an argument and producing the necessary parser, things would be easier. What I mean is, pKeyword_Int = pKeyword "int" pKeyword_Float = pKeyword "float" I tried to create this pKeyword function myself but I couldn't manage to do it. I can feel that, one can simply add a "<* pReturn []" to the ends of every parser and write a recursion with this base condition. Any suggestions? PS: Actually I'm a little bit uncomfortable since there may be such a function in the library already :) -- Ozgur Akgun
