Re: How can I remove this "nil?" check from my code?

Thank you all. I especially like the use of reduce-kv and the 2 fnils. I looked at reduce-kv, but I was too stupid to figure out how to apply it here. On Tuesday, May 26, 2015 at 12:27:16 PM UTC-4, Francis Avila wrote: > > Your two functions can be written more succinctly (and with fewer expl

Re: [ANN] Clojure 1.7.0-RC1 now available

Tassilo, the issue with flatland.ordered.set/ordered-set was that library had never been updated to match the change in hash function that occurred when Clojure 1.6.0 was released. Alan Malloy released a new version of the ordered library today that fixes that. That has no effect on the other CLJ

Leon spot on, maybe ill get to implement such a thing :) On Friday, May 29, 2015 at 2:44:04 AM UTC+3, ronen wrote: > > Gary your last comment hits what I look for exactly: > > "If you are looking for an encoding of clojure's syntax extensions into > pure edn reader tags (as my crystall ball tell

Re: clojure edn function reader

Gary your last comment hits what I look for exactly: "If you are looking for an encoding of clojure's syntax extensions into pure edn reader tags (as my crystall ball tells me you might be), I haven't encountered such a thing yet, even though it's conceivable." My use case is to pass functions

Re: clojure edn function reader

I don't know of any open source implementation of the Datomic function literal. It shouldn't be too difficult and a great excercise. However just using read and eval won't suffice. Datomic creates an anonymous namespace around for each of those functions with the specified requires and imports

Re: Get anonymous function's(which is parameter to function) body in called function

"but it won't give useful information if you don't construct the op inline." The interesting question here is what constitutes useful information! The trade-off is breaking an existing public API. If Shalaka's primary goal is prettier errors in test failures, I'd settle for the fn body itself as

Re: Get anonymous function's(which is parameter to function) body in called function

Hi Shalaka, +1 to what Herwig said. Changing wait-until to a macro seems like the simplest way to tackle this. It gives you access to pred at compile time, does not force the caller to add meta-data to pred, and you can construct the error message as you like. The challenge with your approach 1

Re: clojure edn function reader

Not very clear to me either, but, in the spirit of reducing the field of possible understandings of the question: are you aware of eval? If so, can you reframe your question around it, i.e. what is it missing for your use-case or haw it's not a good fit? (If you are not yet aware of eval, know that

Re: Get anonymous function's(which is parameter to function) body in called function

I'd definitely go with 1.), because the `exec` in 2.) is basically `eval` and thus should be used most sparingly. You can also expand on 1.) by using a macro, that stores the source and other debugging information in metadata and thus get all the benefits of 2.) and then some. -- You received thi

Hi Alex, I've spotted another bug which I've already reported http://dev.clojure.org/jira/browse/CLJ-1739. The problem is that sets of different kinds are equal which is of course expected, e.g., (= #{1 2 3} (flatland.ordered.set/ordered-set 1 2 3)) ;=> true (= #{1 2 3} (java.util.HashSet. [
