Debugging a custom reader literal for a sorted-set

I am having trouble with an implementation of a custom reader literal called #sorted-set. Please see my short code first: https://github.com/xpe/sorted-map-literal Why does this work correctly: (to-sorted-map '(1 2 3 4)) #sorted-map (1 2 3 4) ; correct While this does not? #sorted-map (1 2 3 4)

Re: Debugging a custom reader literal for a sorted-set

That's a good point about: user=> eval (to-sorted-map '(1 2 3 4))) {1 2, 3 4} But this should work, right? user=> (assoc #sorted-map (:a 1 :b 2) :c 3) {:c 3, :a 1, :b 2} ; incorrect -- -- You received this message because you are subscribed to the Google Groups "Clojure" group. To post to this

Heuristic search: convenient memoization?

Background: I'm implementing a heuristic search over a tree of possibilities. The heuristic calculation runs over a map of state. I have a large number of nested functions that support this heuristic. So, for convenience, I often pass around `state` as the first argument in these functions. Ins

Re: Convenient memoization with destructured arguments

I just renamed the subject line since my question has nothing inherently to do with heuristic search. (That was just my particular use case.) This kind of thing can happen in any codebase where destructuring of function arguments is used. On Monday, January 26, 2015 at 12:16:04 PM UTC-5, David

Re: Convenient memoization with destructured arguments

Thanks for mentioning it, Rob. (I have looked at Prismatic Graph before. Putting arguments in a graph (at macro time) is a powerful idea; plumbing uses this to offer a declarative way to offer various evaluation strategies. It is nice to show off Clojure macros! In this case, it makes Clojure f

Re: OO Programmer trying to move to Clojure: Namespace Organization

I often group functions that operate on similar data structures together in a namespace. This isn't always clear-cut, because some functions may "fit" in more than one namespace. I sometimes use a (soft) convention to group functions by the first argument. Yes, this means that my Clojure project

Accessing branches in PersistentTreeMap / sorted-map / CLJ-1008

Summary: I'd like to find a public API to work with the underlying tree of a sorted-map. For example: (def t (sorted-map 1 :a 2 :b 3 :c 4 :d 5 :e 6 :f)) The underlying implementation of sorted-map uses a PersistentTreeMap, which can be accessed with `tree`: (.tree t) ;=> [2 :b] I have not f

Thanks for your comments. I see now that I should clarify: all I really need is public access to the left and right Java methods in PTM. (So, perhaps CLJ-1008 is asking for more than I really need.) It seems to me that since Clojure's RB-Tree implementation (i.e. sorted-map = PTM), it might as

Well, this is question many people ask. :) It is a matter of tradeoffs: - Too many arguments may be an aesthetic problem. It may also reflect a design problem; you might be able to rethink a system to simplify it. (What "too many" means is debatable.) - With many arguments, you may c
