|
||
|
||
;;; Commentary:
|
||
|
||
;; Description:
|
||
;;
|
||
;; This Emacs Lisp package provides a major mode for editing Metafont
|
||
;; or MetaPost sources. It includes all the necessary code to set up
|
||
;; a major mode including an approriate syntax table, keymap, and a
|
||
;; mode-specific pull-down menu. It also provides a sophisticated set
|
||
;; of font-lock patterns, a fancy indentation function adapted from
|
||
;; AUCTeX's latex.el, and some basic mode-specific editing functions
|
||
;; such as functions to move to the beginning or end of the enclosing
|
||
;; environment, or to mark, re-indent, or comment-out environments.
|
||
;; On the other hand, it doesn't yet provide any functionality for
|
||
;; running Metafont or MetaPost in a shell buffer form within Emacs,
|
||
;; but such functionality might be added later, either as part of this
|
||
;; package or as a separate Emacs Lisp package.
|
||
|
||
;; Installation:
|
||
;;
|
||
;; An interface to running Metafont or MetaPost as a shell process
|
||
;; from within Emacs is currently under development as a separate
|
||
;; Emacs Lisp package (meta-buf.el). In order to have that package
|
||
;; loaded automatically when first entering Metafont or MetaPost mode,
|
||
;; you might use the load-hook provided in this package by adding
|
||
;; these lines to your startup file:
|
||
;;
|
||
;; (add-hook 'meta-mode-load-hook
|
||
;; '(lambda () (require 'meta-buf)))
|
||
;;
|
||
;; The add-on package loaded this way may in turn make use of the
|
||
;; mode-hooks provided in this package to activate additional features
|
||
;; when entering Metafont or MetaPost mode.
|
||
|
||
;; Font Lock Support:
|
||
;;
|
||
;; If you are using global-font-lock-mode (introduced in Emacs 19.31),
|
||
;; fontification in Metafont and/or MetaPost mode will be activated
|
||
;; automatically. To speed up fontification for the rather complex
|
||
;; patterns used in these modes, it may be a good idea to activate
|
||
;; lazy-lock as a font-lock-support-mode (introduced in Emacs 19.32)
|
||
;; by adding these lines to your startup file:
|
||
;;
|
||
;; (global-font-lock-mode t)
|
||
;; (setq font-lock-support-mode 'lazy-lock-mode)
|
||
;;
|
||
;; If you are using an older version of Emacs, which doesn't provide
|
||
;; global-font-lock-mode or font-lock-support-mode, you can also
|
||
;; activate fontification in Metafont and/or MetaPost mode by adding
|
||
;; the following lines to your startup file:
|
||
;;
|
||
;; (add-hook 'meta-common-mode-hook 'turn-on-font-lock)
|
||
;; (add-hook 'meta-common-mode-hook 'turn-on-lazy-lock)
|
||
|
||
;; Customization:
|
||
;;
|
||
;; Following the usual Emacs Lisp coding conventions, the major modes
|
||
;; defined in this package provide several hook variables to allow for
|
||
;; local customization when entering the modes. In particular, there
|
||
;; is a `meta-common-mode-hook' which applies to both modes as well as
|
||
;; `metafont-mode-hook' and `metapost-mode-hook' which apply to the
|
||
;; individual modes. In addition, there are several variables and
|
||
;; regexps controlling e.g. the behavior of the indentation function,
|
||
;; which may be customized via `edit-options'. Please refer to the
|
||
;; docstrings in the code below for details.
|
||
|
||
;; Availability:
|
||
;;
|
||
;; This package is currently available via my "TeX Software" WWW page:
|
||
;;
|
||
;; http://www.thphy.uni-duesseldorf.de/~vieth/subjects/tex/software.html
|
||
;;
|
||
;; As of this version 1.0, this package will be uploaded to CTAN
|
||
;; archives, where it shall find a permanent home, presumably in
|
||
;; tex-archive/support/emacs-modes. It will also be submitted for
|
||
;; integration into the GNU Emacs distribution at that time.
|
||
;;
|
||
;; History:
|
||
;;
|
||
;; v 0.0 -- 1997/02/01 UV Started writing meta-mode.el.
|
||
;; v 0.1 -- 1997/02/02 UV Added preliminary set of font-lock patterns.
|
||
;; v 0.2 -- 1997/02/03 UV Improved and debugged font-lock patterns.
|
||
;; Added indent-line-function for TAB.
|
||
;; v 0.3 -- 1997/02/17 UV Improved font-lock patterns and syntax table.
|
||
;; Improved and debbuged indentation function.
|
||
;; v 0.4 -- 1997/02/18 UV Added functions to indent regions for M-C-q,
|
||
;; also added a preliminary mode-specific menu.
|
||
;; v 0.5 -- 1997/02/19 UV Added functions to skip to next or previous
|
||
;; defun and to re-indent or comment-out defuns.
|
||
;; v 0.6 -- 1997/02/20 UV More debugging, testing and clean-up.
|
||
;; v 0.7 -- 1997/02/22 UV Use easymenu to define mode-specific menu.
|
||
;; v 0.8 -- 1997/02/24 UV Added completion function for M-TAB.
|
||
;; v 0.9 -- 1997/03/08 UV Added fill-paragraph function for comments.
|
||
;; Also fixed a few remaining font-lock problems.
|
||
;; Added meta-mode-load-hook to load meta-buf.el.
|
||
;; v 1.0 -- 1997/04/07 UV Cleanup for official public release.
|
||
;;
|
||
;; Historical Footnote:
|
||
;;
|
||
;; This package was begun on February 1, 1997, exactly 20 years after
|
||
;; the genesis of TeX took place according to Don Knuth's own account
|
||
;; (cf. ``The Errors of TeX'', reprinted in ``Literate Programming'',
|
||
;; Chapter 10, p. 249). What better date could there be to choose?
