Support for self-hosted ClojureScript has landed in the test.check repo (https://github.com/clojure/test.check/commit/ebcc57dd631e25ee39bc059899e3bbd9ddf24ee9). Ultimately, when the JAR is available, we could consider perhaps writing a small generative test for some core function and add it to the ClojureScript test suite.

working on a macro which emits compiler warnings by hooking into ana/*cljs-warnings*, not sure if I’m doing it correctly, but it seems to work in my code - my problem is in cljs.test, where I’m getting double macro expansion calls so my warnings appear twice, is this a bug in cljs.test that form like (is (= (my-macro args) :val)) generates code which expands my-macro twice?

fyi: here is how I hook into cljs warnings: https://github.com/binaryage/cljs-oops/blob/7afe8ef49ddb2b7c9c645492bf9211da8b727960/src/lib/oops/core.clj#L257 https://github.com/binaryage/cljs-oops/blob/master/src/lib/oops/compiler.clj

have to go now, in the meantime any pointers how to implement compile-time warnings/errors in my own macros would be appreciated, thanks

I felt like the “easy way" of printing directly to err or out would fail when people used custom warnings handlers or automating the compiler via the API

@darwin I recently logged http://dev.clojure.org/jira/browse/CLJS-1764 which might be related

Test.check is self-host compatible => You can play with it in klipse: http://app.klipse.tech/?cljs_in.gist=viebel/c7aac39eb56f861a7091d144e0042177&external-libs=[https://raw.githubusercontent.com/clojure/test.check/master/src/main/clojure]&eval_only=1

Thanks @mfikes for making test.check self-host compatible
