Full description
a68-mode -- Algol68 major mode
This mode fully supports automatic indentation and font locking (i.e. syntax highlighting) including the three comment styles.
a68-mode supports the classical UPPER stropping regime and the more modern SUPPER stropping implemented by the GCC Algol 68 front-end. The mode will assume SUPPER stropping unless the string "pr UPPER pr" is found anywhere in the program text.
Manual installation
Just put a68-mode.el somewhere in your load-path and require it. Or visit the file with Emacs and M-x package-install-file RET.
Customization
The following variables are available for customization:
- a68-indent-level (default 3): indentation offset
- a68-comment-style-{upper,supper} (default "#"): the default comment style used by e.g. comment-dwim.
see M-x customize-group a68 RET for more info.
Little history of this code
Jose E. Marchesi wrote the first version of a68-mode.el.
At some point someone got a copy of a68-mode.el, renamed it to algol-mode.el and distributed it in github.
Then Omar Polo forked algol-mode.el, renaming it back to a68-mode.el.
Finally at some point Jose decided to ditch his original version and start using and maintain Omar's version instead.
This is that copy.
