Hi bug-gnu-emacs,
Since version 22 Emacs lets scripts begin with a shebang line:
#!/usr/bin/emacs --script
;; Some ELisp code here
This breaks if Emacs isn't installed in /usr/bin, though. Thus, one would want
to write this:
#!/usr/bin/env emacs --script
;; Some ELisp code here
But this doesn't work (env doesn't split its arguments), and it also breaks
even if one is happy with hardcoding /usr/bin/emacs but tries to pass more than
one argument (think -Q and --script). Thus one writes this:
#!/bin/sh
":"; exec emacs -Q --script "$0" "$@" # -*- mode: emacs-lisp;
lexical-binding: t; -*-
(See
http://stackoverflow.com/questions/6238331/emacs-shell-scripts-how-to-put-initial-options-into-the-script/6259330#6259330)
This isn't pretty. Could we set up emacs to assume --script and possibly -Q
when started as "elisp", or "emacs-script", or some other name (that is, could
we make it so that invoking emacs with argv[0] = ".../elisp" starts emacs -Q
--script)? (And ideally Emacs would ignore all options after the script's name,
to let the script itself process them).
Thanks!
Clément.
