;; GNU Emacs 24 major mode for editing Raku code.

;; Currently only provides very basic syntax highlighting.

;;; Code:

(defgroup raku nil
  "Major mode for editing Raku code."
  :prefix "raku-"
  :group 'language)

(require 'raku-detect)
(require 'raku-font-lock)
(require 'raku-indent)
(require 'raku-imenu)

;;;###autoload
(define-derived-mode raku-mode prog-mode "Raku"
  "Major mode for editing Raku code."
  ;; Syntaxification and font locking
  (setq-local syntax-propertize-function #'raku-syntax-propertize)

  (setq-local font-lock-syntactic-face-function #'raku-font-lock-syntactic-face)
  (setq-local font-lock-defaults '(raku-font-lock-keywords nil nil))
  ;; Add imenu support for raku-mode.  Note that imenu-generic-expression
  ;; is buffer-local, so we don't need a local-variable for it.
  (add-hook 'raku-mode-hook 'imenu-add-menubar-index)
  (setq imenu-generic-expression raku-imenu-generic-expression
