Use revamped enrich-classpath plugin #3364

vemv · 2023-07-05T11:09:21Z

Bump enrich-classpath
Introduce clojure.sh script for Clojure CLI usage
Use a reworked middleware for Leiningen integration
- Its new functioning is described in v2 plugin enrich-classpath#23
- It works. On REPL startup, users will see this on the banner:

Because those artifacts are appended at the tail of the classpath (as guaranteed by using a bespoke java command, as opposed to delegating classpath construction to Lein), they won't give problems.

Under this code path, Lein users now run just one JVM!

Might be good to also mention some of things you've written in the description of the PR in the docs.

vemv · 2023-07-05T15:07:12Z

Ready. I've kept QAing this and adding resilience.

Doc got some updates but I'm also leaving a bit minimalistic.

A follow-up PR will add Clojure CLI compat - that work is done already.

vemv · 2023-07-06T12:00:22Z

Moving this to draft again because I'll want to also QA this for figwheel repls.

(I had for shadow-cljs repls only, as far as cljs is concerned)

Otherwise the PR is reviewable.

Note to self: avoid this when the intended repl type is not 'clj.

Not that it's problematic, but seems a sensible way to start.

vemv

(Mostly a note to self)

For Lein users, it would be important to evaluate the Lein :init code.

Perhaps CIDER can make this happen, e.g. we determine the final :init value (after applying profiles, plugins, etc), persist it or store it in memory, and then we evaluate CIDER-side it as the first thing that happens after a successful (and enriched, i.e. no fallback was applied) connection.

edit: maybe it simply can be a clojure.main arg here https://github.com/clojure-emacs/enrich-classpath/blob/585f80f12b610b2438492e7523582796c5c1ee03/lein-plugin/src/cider/enrich_classpath/plugin_v2.clj#L90

vemv · 2023-08-14T21:18:37Z

@bbatsov: this is starting to look great, however I plan to merge it after the 1.8.0 release to contain risks.

This way, users can choose to use 1.8.0 or master.

vemv

I've been refining the Clojure CLI integration (both in https://github.com/clojure-emacs/enrich-classpath itself and the clojure.sh wrapper script, now included in the PR).

I'm more confident about it now and have successfully tried with CIDER in large projects.

vemv · 2023-08-19T06:13:30Z

+  (lambda ()
+    (when (symbol-file 'cider-jack-in-command)
+      (concat (file-name-directory (symbol-file 'cider-jack-in-command))
+              "clojure.sh")))


I intend to ship the clojure.sh wrapper into the artifact to be unzipped into ~/.emacs.d/elpa/cider[...]

symbol-file would help me find that.

SGTY? @bbatsov

Bundled with what - CIDER or enrich?

Ah, I see it's bundled with CIDER. I'm not sure what symbol-file does, but there's package-user-dir or something like this that specifies the path to ELPA, so it seems you can use it instead.

I just want to mention that package-user-dir seems to only be used by package.el. So if you are using something like straigth.el to manage your Emacs packages (like I do), my CIDER files won't be in the directory contained in package-user-dir. E.g., package-user-dir in my case contains "~/.emacs.d/elpa", but my packages are at ~/.emacs.d/straight-emacs-29/straight/build/ (for Emacs 29.1; I keep a separate package directory per Emacs version).

(symbol-file 'cider-jack-in-command) on the other hand gives me "/home/iarenaza/.emacs.d/straight-emacs-29/straight/build/cider/cider.elc" which seems about right 😄

Agree with @iarenaza to not use package-user-dir (personally I use borg as package manager).

I think using locate-library is pretty common and I saw it a few times where the packages needs to find the sources for compiling a native module like vterm or jinx.

For cider this would be something like:
(file-name-directory (locate-library "cider.el" t))

My bad, I keep forgetting not everyone is using ELPA. :-) I agree that locate-library is probably the best approach (mostly because it's obvious what you're trying to do with it).

bbatsov · 2023-08-23T04:58:48Z

Seems the windows integration tests are failing all the time now. Perhaps there's some real problem with them?

+  "The location of enrich-classpath's clojure.sh wrapper script."
+  :package-version '(cider . "1.8.0")

Seems weird that something that looks like a filename should be a function IMO.

bbatsov · 2023-08-23T05:10:48Z

cider.el

+                           (executable-find (funcall cider-enrich-classpath-clojure-cli-script)))


Here it also looks that this is a function. Perhaps you can just have a function that just expands properly whatever is in the defcustom (e.g. tries to find whatever was specified by the user and falls back to clojure.sh)?

I tentatively left this as a simple defun, and with a clearer name. Users would rarely have the need to point elsewhere for the script.

One can always edit the script inline, create a symlink, etc.

Seems the windows integration tests are failing all the time now. Perhaps there's some real problem with them?

Probably not. In Circle they're passing as usual, while GHA's jobs have been more flaky.

Maybe their Win servers were having a slow day.

Looks OK to me in the current state. I guess we'll squash this down to 1 commit, right?

Thanks!

I'm fixing something in enrich itself, will squash afterwards.

It now is in. clojure.sh works when distributed by melpa and located CIDER-side.

@iarenaza, @dakra, given that you had the generosity to review, you might also want to give it a spin?

Doc lives at https://docs.cider.mx/cider/config/basic_config.html#use-enrich-classpath

Cheers - V

iarenaza · 2023-08-29T15:44:02Z

Am I right in assuming that I need master for that to work? (just to make sure, as I'm running CIDER 1.7.0 right now).

bbatsov · 2023-08-29T16:34:58Z

@iarenaza Yeah, you need to be on master.

vemv · 2023-08-29T16:41:31Z

Be advised, I already got quite some feedback, nothing critical, but enough for not bothering more people (yet).

Either way, CIDER 1.7.0 -> 1.8.0 has lots of reliability improvements (changelog), so feedback for all those other areas would be most useful.
