Hayoo http://hayoo.fh-wedel.de has been relaunched. Hayoo is a search engine for Hackage packages, which allows you to search for functions, data types and packages.
It is currently work in progress. Any feedback is greatly appreciated!
Thanks for this fabulous search engine that covers all of hackage! But I have feedback. :)
Yesterday, I was trying to search for the operator (^?!), but no results. Today, I found that I have to put it in quotes, so the following queries work: "(^?!)", "^?!". I guess that one of the three symbols has some special meaning in the query language, but would it be possible to change the lexical syntax to match Haskell's syntax? I.e. any valid Haskell identifier is also a valid search query. (I'm happy to put parentheses around operators.)
I experienced something similar/related by simply querying for "foldl'" (without the quotes):
Internal Error: (line 1, column 6): unexpected '\'' expecting "\\", "^", space, white space, "++", "NEAR", "FOLLOW", "AND", "OR" or end of input
The query succeeds when using "foldl'" with the quotes. I'm not sure whether it's intentional for those queries to fail, but it feels counter-intuitive. Anyway, next to that: thanks for your work on Hayoo! Nicolas
