Re: Clojure for LISP programmers....

I generally like that Clojure dispenses with parens that exist for the benefit of the evaluator rather than the developer; thus far fewer parens when using (cond). Still, my old Lisp habits (20 years without use) succumbed as much as Simons. See my earlier thread about exception reporting. Coul

Re: Clojure for LISP programmers....

Hi Simon, there is a detailed explanation of syntax, data structures etc. as well as a complete reference at the Clojure site[1]. Then there's a wiki[2] with a lot of information of setting Clojure up with different editors like emacs or vim and a lot of examples. Also explaining some of the qui

Re: Clojure for LISP programmers....

I never read anywhere in the documentation or in the user group that Clojure is a Common LISP implementation. Since it's existence, LISP has not gained a large acceptance in the commercial market compared to other "conventional" programming languages. I started to use it 28 years ago (UCI Lisp on

Hi folks, I made some small changes to clojure.contrib.test-is: 1. *test-out* now defaults to standard output (instead of standard error). This should be better for SLIME users. 2. Based on Frantisek Sodomka's suggestions, I've added two convenience macros, each= and all-true: user=> (doc all-t

Another idea I had was this (and I haven't had a chance to check the source code to see if any of this is already implemented): When Clojure creates a new Java class for a function, it should find a way to hang the meta-data for the function as a static field on the function. Alternately, there

Re: A value that equals everything, or, ignoring things in multi-dispatch

what i think would be nice here is multimethods taking multiple dispatch functions. (i'm not sure how you'd do that without breaking the default value syntax) so it'd try the first function, and if it doesn't match any method, then it tries the second, etc. then :default, then throws an exception

Allowing she-bang lines?

One (hackish) solution would be to write a wrapper script in some other scripting language that chops off the #! line before running Clojure. But maybe, as a special case, the Clojure reader could ignore #! on the first line. I think some Schemes do that. -S On Nov 15, 7:52 pm, Jeff Rose <[EMAI

Re: A value that equals everything, or, ignoring things in multi-dispatch

All multimethods have :default as the default fallback value, regardless of what the dispatch function is. But I assume that only works with single values. Maybe what you want is TWO multimethods, one that dispatches on the first value, then calls the second multimethod to dispatch on the other

One way I could think of to do this would be to build a map with each unique item as a key and the count as its value. Then it would be trivial to pull out the keys with the count as a specified value. I started writing this, but my SLIME is royally screwed up right now after the upgrade to Clojur
