;;; Commentary:

;; Much like ~/.emacs.d/gnus.el, this is eshell-specific configuration that's
;; loaded whenever `eshell' is loaded.

;;; Code:

(require 'setup)

;;; Environment
(setenv "PAGER" "cat")

;;; Aliases

(dolist (definition '(("e" . "find-file $1")
                      ("ff" . "find-file $1")
                      ("emacs" . "find-file $1")
                      ("ee" . "find-file-other-window $1")))
  (eshell/alias (car definition) (cdr definition)))

;;; Functions

;;; Extra eshell packages

(setup (:straight esh-autosuggest)
  (:hook-into eshell-mode))

(setup (:straight esh-help)
  (require 'esh-help)
  (setq-local eldoc-documentation-function #'esh-help-eldoc-command))

(setup (:straight eshell-syntax-highlighting)
  (eshell-syntax-highlighting-global-mode +1))

(setup (:straight-if fish-completion
                     (executable-find "fish"))
  (:autoload global-fish-completion-mode)
  (global-fish-completion-mode +1))

;;; Miscellaneous

;; Fix modeline
(when (boundp 'simple-modeline--mode-line)
  (setq mode-line-format '(:eval simple-modeline--mode-line)))

;;; Tell Emacs our customizations are loaded.
(defvar eshell-customizations-loaded t
  "Whether eshell's customizations have been loaded yet.")
