;;; test-prog-shell--format-wiring.el --- Verify the Shell formatter is wired -*- lexical-binding: t; -*-

;;; Commentary:
;; The shfmt use-package gates on `:if (executable-find shfmt-path)' so
;; the keymap entries only install when shfmt is on PATH. The bind/
;; fboundp tests therefore call the executable-skip helper first.
;;
;; Three checks for the shell formatter, each repeated for the two
;; relevant mode-maps (`sh-mode-map' and `bash-ts-mode-map'):
;;   1. `shfmt-buffer' is fboundp.
;;   2. C-; f in each map resolves to `shfmt-buffer'.
;;   3. The `shfmt' executable is on PATH.
