ASK: Emacs inferior-arc on Windows
2 points by archie 876 days ago | 7 comments
Hi guys!

I'm trying to configure arc mode in emacs and inferior-arc on MS Windows machine. To this end, I put this content in my .emacs file:

  (add-to-list 'load-path "C:/path/to/anarki/extras")
  (autoload 'run-arc "inferior-arc"
    "Run an inferior Arc process, input and output via buffer *arc*.")
  (autoload 'arc-mode "arc"
    "Major mode for editing Arc." t)
  (add-to-list 'auto-mode-alist '("\\.arc$" . arc-mode))
  (setq arc-program-name "C:/path/to/runarc.bat")
Here's the content of the runarc.bat file:

C:/path/to/Racket.exe -e "(require anarki) (current-directory anarki-path) (anarki-repl)"

Now, arc mode seems to work OK, but here's the problem: when I start arc repl from Emacs (with M-x run-arc), the arc prompt is not displayed. Although I can type in the expressions in repl, nothing is printed back as a result of evaluation. Only when I type in some wrong expressions I get the usual arc error messages printed. It seems like only stderr is printed, but stdout isn't. I don't know what I'm doing wrong and how to correct this. Any help???

I'm a big Emacs fan. I'll check this out when I'm home.

No answer, huh? It's really an annoying problem...

Ah, sorry I missed that. Right now (on Linux), I'm not even getting as far as you are. Upon M-x run-arc, I'm getting this error:

    emacs: /home/zck/programs/arc/arc3.1/ Exec format error

    Process arc exited abnormally with code 126

Hmmm, interesting. But I don't have any problem on my linux machine, only Windows is problematic. Here's mine .emacs setup on linux:

  (add-to-list 'load-path "~/.racket/6.4/pkgs/anarki/extras")
  (autoload 'arc-mode "arc"
    "Major mode for editing Arc." t)
  (add-to-list 'auto-mode-alist '("\\.arc$" . arc-mode))
  (setq arc-program-name "~/.racket/6.4/pkgs/anarki/arc -n")
  (add-hook 'inferior-arc-mode-hook
  	    (lambda ()
	      (set (make-local-variable 'comint-use-prompt-regexp) t)
	      (set (make-local-variable 'comint-prompt-read-only) t)))

Are you able to get inferior-lisp working on Windows? Maybe the appropriate forum could help with any gotchas there?

If you do figure this out don't forget to come back and tell us!

Oh, weird. Then I'm less able to help you, as I don't have a Windows computer. Sorry about that.

I have no experience with Emacs, sadly, but hopefully someone here does and can share a working setup.
