Apheleia with zprint question

[mihai-dinu]

Hi Anders, I didn't know how else to contact you other than this so here I am creating an issue for a question. I found your blog where you were using zprint for clojure formatting. I have tried using it as well, but without success. My problem is that it looks like Apheleia is calling it's formatters with make-process and that does not work well with shell redirection as far as I could tell.

Here is my apheleia use-package

(use-package! apheleia
  :defer t
  :hook ((typescript-mode . apheleia-mode)
         (javascript-mode . apheleia-mode)
         (js2-mode . apheleia-mode)
         (clojure-mode . apheleia-mode))
  :config
  (setf (alist-get 'clj-zprint apheleia-formatters)
        '("clj-zprint"
          "{:style [:community :justified] :map {:comma? false}} <"
          file))
  (add-to-list 'apheleia-mode-alist '(clojure-mode . clj-zprint)))

And here is what I've tried to reproduce the issue:

(defun testcmd ()
  (let* ((command '("clj-zprint"
                    "{:style [:community :justified] :map {:comma? false}} <"
                    "/Users/dimiha/code/personal/clojure/fwpd/src/fwpd/core.clj"
                    ))
        (proc (make-process
               :name "zprint"
               :buffer (current-buffer)
               :command command)))))

(testcmd)
Unknown switch '/Users/dimiha/code/personal/clojure/fwpd/src/fwpd/core.clj'

Process zprint exited abnormally with code 1

As you can see, the process exits with status code 1 and what I think happens is that Emacs doesn't know how to do stdin redirection (<) when running a process outside a shell.

Have you had this problem as well? Or do you have any ideas why this is happening?

Thanks in advance!
