bnfc-mode simplifies editing BNFC input files in Emacs. BNFC is a handy tool for converting context-free grammars into parsers, syntax highlighters, and documentation.
Input files are in a language called Labelled BNF. As a context-free grammar, it's capable of describing itself. Here's a screenshot of part of that grammar in bnfc-mode.
- Syntax highlighting via
font-lock-mode - Automatically loads on files with
*.cfextension - Comment/uncomment lines using
M-;
The recommended way is via MELPA, but it can also be installed manually.
