I often work with YACC (Bison) grammars, but still didn’t find comfortable editor for them. So I’m still using Notepad for this purpose. However, some time ago I found Perl script called
linkify.pl as far as I remember, which produces HTML page based on the grammar and the list of non-terminal symbols. Edward Smirnov, colleague of mine, take this script and bring it to the completely new level.
What are the benefits of using such generated HTML page?
- You can go exactly to whatever line number just adding
- You can go exactly to the place where nonterminal symbol is defined.
All nonterminal symbols on this page are the links to theirs definitions indeed. Thus you may easily go down from the start symbol to the tokens using these links. One more benefit is that you may use “Back” browser button for one level up return.
- Last but not least. Syntax highlighting: comments are grey, nonterminal symbols are close to red, the code and terminal symbols are navy.
