LkbMode

(comment: Why not merge this page with LkbEmacs?)

There are some emacs lisp extensions to make life easier when you are running the LKB from within emacs,

lkb.el (available here) adds an LKB menu to the emacs menu bar and provides some useful keybinds (see below).

tdl-mode.el (available here) creates a mode for editing TDL called tdl-mode that provides syntax highlighting and lines up elements in the tdl expressions.

Install with:

;;; load them
(load-file "/path/to/lkb.el")
(load-file "/path/to/tdl-mode.el")
;;; use it for .tdl and .mtr files
(add-to-list 'auto-mode-alist '("\\.tdl\\'" . tdl-mode))
(add-to-list 'auto-mode-alist '("\\.mtf\\'" . tdl-mode))
;;; make a menu of types in this file
(add-hook 'tdl-mode-hook
          (function (lambda ()
                      (imenu-add-to-menubar "Types"))))

They are both installed as part of Logon.

Key Bindings

There are also some general key bindings for controlling the lkb when using LkbEmacs.

The "⁁" shows where the cursor is placed at the end of the command.

• C-c p: parse using the main grammar (lkb::do-parse-tty "⁁")

• C-c r: parse using a client grammar

  • (mt::parse-interactively "⁁")

  C-c u: start a client grammar

  • (tsdb::tsdb :cpu :⁁ :file t)

  C-c g: load a grammar

  • (lkb::read-script-file-aux "~/⁁/lkb/script")

  C-c G: reload a grammar

  C-c i: index for generation

  C-c I: reload and index grammar

  C-c l: show a word (unexpanded)

  • (lkb::show-word-aux-tty "⁁" nil)

  C-c L: show a word (expanded)

  • (lkb::show-word-aux-tty "⁁" t)

You can also use commands from Inferior Common Lisp, such as the extremely useful:

• C-c C-p:find the previous command

  • fi:pop-input

  C-c C-n: find the next command in the ring

  • fi:push-input

Troubleshooting

Older versions of emacs use insert-string(), while newer versions use insert(). The newest version of lkb.el can handle both (thanks to Stephan Oepen and Joshua Crowgey).
