How are folks connecting Calva to the Exercism Clojure exercises?
exercism download to get a local copy of one of the exercises, and then open a parent folder in VS Code (the parent
clojure folder will do), I can then open the
.clj file in the
Now I follow the “Jack-in” instructions and hit
ctrl-option-j. That pops up the “Jack-in” menu where I’m asked for the “Project Type”. I know the test runner on the server uses Babashka, and there’s a
projects.clj file (provides Leiningen support?), but I just went with a softly-softly approach and chose deps.edn. I opted to not pick a launch target on the next pop-up because I figure
:tests is not for launching a REPL??
This seems to do the trick, and I can
ctrl-enter to my heart’s content. I still run the tests from the command line, and I don’t know what else I’m missing out on. Is there a better way?
If you like, you can make use of the Calva test runner or debugger, but I find them to be somewhat superfluous.
I run the tests directly from the editor by evaluating
(clojure.test/run-tests) from the test namespace.
There’s no reason not to select
Babashka from the project type menu, which has the benefit of instantaneous startup.
One tool I really enjoy is RCF: hyperfiddle/rcf: RCF – a REPL-first, async test macro for Clojure/Script (github.com)
It gives you a
tests macro that lets you define test cases in the same file as your source code, so then you don’t need to switch files all the time!
Here is a video demo I made: Fizzbuzz demo with RCF - YouTube
Great, that clears it up a lot!
deps.edn is not causing me trouble so far, but nice to know about
Babashka. And I see the “Calva test runner”
ctrl+alt+c t command is quite handy for running all the tests.
Great vid too. I’m very new, but standard RCF’s are serving me well at the moment. Again, great to know of options.
