;;; find-script.el --- Find a script in $PATH -*- lexical-binding: t; -*-

|
|
;;; Commentary:
|
|
|
|
;; This package makes it easier to find a script to edit in $PATH. The initial
|
|
;; `rehash-exes' is slow, but it's stored in `*exes*' as a caching mechanism.
|
|
;; However, I'm sure it could be improved.
|
|
|
|
;; In addition, `*exes*' currently contains /all/ executables in $PATH, which
|
|
;; ... maybe only the ones stored in some text format should be shown.
|
|
|
|
;;; Code:
|
|
|
|
(defvar *exes* nil
|
|
"All the exectuables in $PATH.
|
|
Run `rehash-exes' to refresh this variable.")
|
|
|
|
(defun rehash-exes ()
|
|
"List all the executables in $PATH.
|
|
Also sets `*exes*' parameter."
|
|
(setq *exes*
|
|
(cl-loop for dir in exec-path
|
|
append (file-expand-wildcards (concat dir "*"))
|
|
into exes
|
|
finally return exes)))
