I was writing some code the other day and found it helpful to have a
function to expand a command name to its full-path -- somewhat like
`expand-file-name'. I didn't manage to locate a function that does
this already so I wrote one. Is there already something like this?
Below is one implementation:
(defun expand-command-name (name)
"Expand command NAME to a full-path filename by searching `exec-path'."
(let ((paths exec-path)
(while (and paths (not path))
(setq path (file-name-completion name (car paths)))
(setq full-path (concat (car paths) "/" name)))
(setq paths (cdr paths)))
- function `expand-command-name',
