Enable calling clojure.tools.namespace.repl/set-refresh-dirs as part of setup.

[grzm]

.cljc files in /resources/ (such as those copied there during figwheel compilation) are picked up by default during clojure.tools.namespace.repl/refresh, which can stomp on code loaded into memory by test-refresh. By exposing clojure.tools.namespace.repl/set-refresh-dirs in some way as part of the test-refresh run, we can avoid this from happening.

For more detail, see a blog post I wrote detailing how I worked around the same issue with the Reloaded workflow

I believe this only needs to be called once, not on every test run. Perhaps have a "setup-fn" that's specified in project.clj and called in leiningen.test-refresh/test-refresh?

Interesting problem.

Allowing a generic setup-fn would allow lein-test-refresh users to do whatever they want (depending on implementationeither prior to every test run or just once before running any tests). That is an interesting approach as it would let people do whatever they want and I think would enable some neat things. If implemented for solving this problem it does put quite a burden on user of lein-test-refresh. I think the function would need to be called in the com.jakemccrary.test-refresh/monitor-project as that is when code is being evaluated within the context of the project.

Another approach would be to add a :refresh-dirs option that is similar to the :watch-dirs option. This feels a lot easier for users.

I won't be able to give a shot at either solution until sometime later this week. I'd most likely accept a PR for :refresh-dirs immediately. I'd need to think about the setup-fn idea a bit before getting that feature into the codebase.

Actually, was thinking about some weirdness I've been seeing in one of my own projects and wondering if its because of this problem. Going to build out the first option today.

Released 0.16.1-SNAPSHOT with a :refresh-dirs option. Check the sample.project.clj for what it looks like.

Sort of wondering if :watch-dirs and :refresh-dirs should be collapsed into a single option. I'm having a difficult time coming up with a scenario in which you would set one and not the other.

Thanks! From my initial testing, setting :refresh-dirs with 0.16.1-SNAPSHOT works for me!

I don't know enough about how Figwheel does its compilation, but I wonder if Figwheel could be convinced to place its compilation someplace other than where the final JavaScript output ends up. Of course that's an issue for a different project :)

Thanks again for your quick response!

Just released a non-snapshot release, 0.17.0, with this feature.

Thanks!
