i'm trying learn arrows, how parrows can replace parsec, there nonexistent number of tutorials. believe benefit lot simple examples, so, given binary tree: data tree = node tree tree | | b deriving show how can parrow used parse string similar to: "((a b) (a (b a)))" so becomes: node (node b) (node (node b a)) this not cleanest answer, managed with: import text.parsercombinators.parrow import control.arrow data tree = node tree tree | | b deriving show text = "((b a) (a b))" fromtoken :: char -> tree fromtoken 'a' = fromtoken 'b' = b token = anyof "ab" >>> arr fromtoken node = arr (uncurry node) <<< ((char '(' >>> token <+> node) -- left side >>! white -- whitespace &&& ((token <+> node) >>! char ')')) -- right side main = print $ runparser node text mind i'm still working on ar...

i creating bunch of foo objects in gae. i want each foo have function called fooify(). calling fooify(object) should return object, transformed in way. for example, fooify([2,3]) might return: [1,2] (fooify = lambda x: [n-1 n in x]) [2,3] (fooify = lambda x: x) [2,4] (fooify = lambda x: [x[0],x[1]+1]) i want able define fooify when create objects, preferably like: foo1=foo() foo1.fooify=lambda x: [n^2 n in x] foo1.put() the foo class looks like: from google.appengine.ext import ndb class foo(ndb.model): name=ndb.stringproperty(default="generic foo", indexed=true) fooify=ndb.somethingproperty(indexed=false) # contains function i know isn't datastore made for, still it. option can see following: class foo(ndb.model): name=ndb.stringproperty(default="generic foo", indexed=true) fooify_str=ndb.stringproperty(indexed=false) # contains "lambda x: [n+3 n in x]" def fooify(self,obj): func = eval(self...
