;;; Commentary:

;; Extra expansions for editing JSP files. To be used in conjunction
;; with the html-mode expansions
;;
;;     er/mark-jstl-escape
;;
;; These expansions aren't loaded by default, so you'll have to explicitly
;; ask for them in your init file with:
;;
;;     (eval-after-load 'sgml-mode '(require 'jsp-expansions))
;;
;; Feel free to contribute any other expansions for JSP at
;;
;;     https://github.com/magnars/expand-region.el

;;; Code:

(require 'expand-region-core)

(defun er/mark-jstl-escape ()
    "Mark jstl-escape presumes that point is outside the brackets.
If point is inside the brackets, they will be marked first anyway."
    (interactive)
      (when (or (looking-at "\\${")
            (er/looking-back-exact "$"))
    (forward-char 1)
    (search-backward "\$")
    (set-mark (point))
    (forward-char 1)
    (forward-list)
    (exchange-point-and-mark)))

(defun er/add-jsp-expansions ()
  "Adds JSP-specific expansions to the buffer"
  (set (make-local-variable 'er/try-expand-list) (append
                                                  er/try-expand-list
                                                  '(er/mark-jstl-escape))))
