2:44 osfameron: is there a way to stop an (iterate) on a condition?
2:44 e.g. an equivalent of (reduced) ?
2:45 I was going to say "the docs for iterate don't mention anything" but then again, the docs for *reduce* don't mention this either...
2:46 rhg135: You don't stop a lazy sequence iirc
2:47 You just stop consuming it
2:47 osfameron: nah, reductions is a lazy sequence, and can also be terminated by (reduce)
2:47 it's up to a given sequence whether it wants to terminate or not
2:48 e.g. you can produce a finite range lazily too
2:48 rhg135: take-while
2:49 osfameron: yeah, that'd probably be the simplest way to implement what I want
2:49 of course take-while also returns a lazy-seq :D
2:51 thanks for suggestion, saves me implementing something more complex in meantime
3:01 BigSafari: im storing a cookie in ring middleware cookie-store. the data i store is a hashmap with a joda.datetime object inside. but the reader is having trouble reading the cookie back in, because the reader does not know hos to parse the datetime object. error: No reader function for tag object. can i define a reader function for such an object?
3:03 dysfun: BigSafari: i don't think you can pass extra readers to the cookie store
3:06 BigSafari: im just storing a hashmap from a database record, which includes a joda datetime. is there a better format for the datetime which is supported by the reader?
3:08 rhg135: int if you like being vague
3:08 BigSafari: nice one :-)
3:08 dysfun: you can convert it to an instant
3:09 instants have a built in reader tag
3:09 but make sure to put it into UTC first :)
4:42 m1dnight2: Im trying to make two macros: one that holds a symbol (I think?) which represents a variable, and then one that injects that symbol into another macro. But Im finding it hard to make it work
4:43 dysfun: well macros don't 'hold' anything
4:43 I can't realy explain it well :p But what I'm trying to achieve is something I need for another macro. This is a minimal test case
4:43 dysfun: why is vars a macro? it can be a function
4:44 m1dnight2: So as I understand it, the vars macro takes a symbol and turns that into a regular clojure value. Then I want to take that value and turn it into an AST again (I call the values that are parameters to the macro "AST"s)
4:44 It's a technique I need for another larger macro
4:44 dysfun: yeah, but what i mean is the outer macro stops the forms from being evaluated, then it's just regular clojure data that can be passed to functions, which can use the same tricks
4:44 m1dnight2: Basically, I have a macro "create-actor" and that will expand to a blueprint for an actor. And when I call (spawn actordef) I want to construct a function from that
4:45 But if I call (vars [x y z]) as a function, it will evaluate x y and z, and those are not supposed to be bound
4:46 dysfun: sure, but you're effectively calling (vars '[x y z]) because they're not evaluated to start with
4:46 m1dnight2: Rabble, my explanation is not clear enough, sorry
4:46 Euh, I think I have a more telling example. I'll be back sec :p
4:46 dysfun: as will i in a couple of minutes
