SUGGESTION: Rewrite in pure Emacs Lisp (and fails to run nrepl on MacOS)

[rswgnu]

This would be so much more useful if you wrote a replica in pure Emacs Lisp, removing all Clojure dependencies as getting Clojure setup properly can be quite involved.

For example, I used 'brew' on MacOS to install clojure and leiningen but flower still did not work, some failure in starting up the repl, even though it found it in the path.

Thanks for the suggestion @rswgnu - sounds good but it requires some enormous investment of effort

The most probable issue which prevents the Emacs setup from working might be the same one which prevent pure Clojure version from working: #95 (comment) (we need to release new version which already includes fixes).

Please stay with us for a while. Output from Emacs startup logs will be also be very helpful here.

@rswgnu also please consider that default installation of Emacs on Mac OS X cannot find Leiningen in its exec-path which doesn't include /usr/local/bin by default, so some additional steps like (add-to-list 'exec-path "/usr/local/bin") may be required (just reproduced this today).

Thanks for the tip but /usr/local/bin is in my PATH.

Here's the stack trace and cascading list of unfound libraries in the error on MacOS 10.14.6:

Yes, seems the same as in #95 (comment)

I won't be closing the issue as duplicate until fully checking that everything works in Emacs as intended.

Thank you again for the issue. You will get a comment here once we build new release with @harlov

Based on the issue profitware linked to above, I just substituted flower and clojure versions in the Emacs flower/project.clj file and things started working. So you could fix this by just making these updates without even having to merge the new branch.

Thank you for the workaround. Let it reside here until branches merge.

@rswgnu please check if 0.4.7 release version works for you. It has been updated in MELPA already: https://melpa.org/#/flower
