Hi List,
assume this works in a shell
,------------------------
| $ prg -'fun "strg" num'
`------------------------
with 'prg' being a shell-command (for bash on GNU/Linux) calling a program,
'fun' being a function defined in that program, 'strg' being a string argument
to that function, and 'num' being a numeric argument to that function.
The task is to make a string out of this in an Elisp program and give
this 'cmd' as single argument to an Elisp function that then does
something like
#+begin_src emacs-lisp
(let ((cmdlist (split-string cmd)))
(set-buffer (apply 'make-comint "buffer-name" (car cmdlist)
nil (cdr cmdlist) ) ))
#+end_src
Experimenting with (format "%s %S etc" ...) and (shell-quote-argument..) did
not result in anything that works. It seems the outcome is either
,--------------------
| prg -'fun strg num'
`--------------------
or
,------------------------
| prg -'fun \"strg\" num'
`------------------------
or
,--------------------------------
| prg\\ -\\'fun\\ \\\"strg\\\"\\ num\\'
`--------------------------------
or something similar, all resulting in errors.
Trying to replace the single quotes in that line with double-quote did not
work either.
How can I quote such a 'cmd' string in a way that it finally arrives as
,------------------------
| $ prg -'fun "strg" num'
`------------------------
?
