I've also preferred the Clojure doc style, under the theory that arglists are meant for humans, who can tell whether a boolean or optional arg is probably meant from context, and not autocompleters. -- Stephen Compall ^aCollection allSatisfy: [:each|aCondition]: less is better -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: Compilable clojure program, but unreadable?
Hi, Is this inconsistent behaviour: user=> `s/foo s/foo user=> ::s/foo # nil user=> (require '[clojure.string :as s]) nil user=> `s/foo clojure.string/foo user=> ::s/foo :clojure.string/foo I think that ::s/foo should be resolved to :s/foo if there is no alias for s (like symbols).

The reader page says, with :: they are resolved in the current namespace.

Automatically generating test-cases for functions (problem with macros)
Hi!
I've written a macro to generate tests for functions that have the ":_test"
key in their metadata. I know that clojure.test automatically runs tests
associated with ":test" keys, but I'd like to implement my own test-case
generation.
Here' what it looks like:
(defn my-last
"P01 (*) Find the last box of a list."
{ :_test '(= (my-last '(a b c d)) 'd) }
[lst]
(if (<= (count lst) 1)
(first lst)
(recur (rest lst
(defmacro gen-tests []
`(do ~@(for [f (map first (ns-publics *ns*)) :when (:_test (meta
(ns-resolve *ns* (symbol f]
`(clojure.test/deftest ~(symbol (str f '-test)) (clojure.test/is
~(:_test (meta (ns-resolve *ns* (symbol f)
The gen-tests macro basically enumerates all publics in the current
namespace and generates a 'deftest' declaration for each function that
contains the ":_test" key in its metadata.
I'm sure there exists more reasonable and idiomatic way to do the same
thing. Specifically, I'd really like to remove the repeating "(:_test (meta
...)" part, but I wasn't able to come up with the solution myself.
Any help will be appreciated. Thanks!

Re: how to restart Clojurescript One repl the right way?
Yes, good question. It leads to another one: is ther a clojure hook to stop the server ? I personally kill the process to sweep out the vm and then can restart again.

When you get a BindException error like the one you have it's probably because your ring server didn't shut down properly when your repl disconnected. I always have to resort to looking up the pid(in Linux) and killing the process running on the address:port and running lein repl again or cljs-repl if you are still within the clojure repl. I think this situation can be remedied somehow if the server connection can be saved to a var so that a stop and start function can be called on it.
