I think that error message would be easier to understand if it started with

spec error add a bunch of text so the location somehow gets lost in the noise

thheller08:03:34

but so far using clojure.core.specs just works 😉

Hello everyone! Does this http://dev.clojure.org/jira/browse/CLJS-1954 affect current 1.9.494 release?

thheller10:03:46

yes, waiting for the new Closure release

jetzajac10:03:53

BTW I see this ticket https://github.com/google/closure-compiler/issues/2336 closed 3 days ago

thheller10:03:49

closure does a release once a month usually

jetzajac10:03:19

do we really have to wait for release or maybe we can build something up by ourselves out of this commit? 😃

thheller10:03:30

you can, but it isn't easy 😛

jetzajac10:03:54

oh.. we kinda stuck between broken cljs releases. there are 3 things that are broken in different versions and there is no one out there that works for us. are there any tricks I need to know on how to build cljs against custom closure compiler?

thheller10:03:53

don't need to build custom CLJS, just build and include the updated closure compiler in your dependencies

thheller10:03:23

someone in #clojurescript did that the other day, forgot who though

thheller10:03:57

oh no wait it was here @martinklepsch

jetzajac10:03:04

doesn’t sound too hard. will try to do so, thanx a lot!

martinklepsch10:03:13

@jetzajac I linked a repo here that has instructions for building Closure Compiler locally

martinklepsch10:03:25

Oh and also Closure Compiler readme has good instructions now
