Hi list,
I have a small Ruby CLI program that I want to call from emacs. This script
simply opens an emacs orgmode file from a specific location in my hard
drive, and does some text processing. When I call it from the terminal
directly, it works fine. When I call it from emacs, the script fails with
an encoding error.
I'm using this elisp to call it from emacs after a buffer is saved:
(defun test ()
> (let ((universal-coding-system-argument 'us-ascii-mac))
> (shell-command "/Users/myself/.rvm/bin/rvm ruby-1.9.3-p194 do
> /usr/bin/myrubyscript")
> ))
> (add-hook 'after-save-hook 'test)
After I save a buffer, the shell-command function is fired, but I get the
following output in the "*Shell Command Output*" buffer:
F, [2012-08-30T01:59:18.688827 #94004] FATAL -- : invalid byte sequence in
> US-ASCII (ArgumentError)
> /Users/myself/.rvm/gems/ruby-1.9.3-p194/gems/org-ruby-0.6.3/lib/org-ruby/parser.rb:89:in
> `split'
> /Users/myself/.rvm/gems/ruby-1.9.3-p194/gems/org-ruby-0.6.3/lib/org-ruby/parser.rb:89:in
> `initia
The strange thing is that the file that this script opens *is* accessible,
and is the same file it would open if it were fired up from the terminal.
For some reason, Emacs is getting in the way, but I have no idea what that
could be. Am I missing something? If someone could enlighten me here, I'd
be really grateful!
Thanks in advance,
- Marcelo.
