[Sdl-developers] ABNF Grammar

[Daniel Leuck]

Hi Jesse,

 

I would just write a method to consume the multiline comments during the
tokenization phase.  At this point, I don't think SDL's grammar is complex
enough to require use of a parser generator.  I considered using JJTree as
we do for BeanShell (https://javacc.dev.java.net/doc/JJTree.html), but I
discovered writing it by hand wasn't too hard, and the Java and C#
implementations are very fast.

Just in case it makes a difference, I'm writing a completely handcoded
recursive descent parser for the C++ version (Boost::Spirit is a lot of
library overhead). Right now, the parsing functions for each part of the
grammar will look at the text stream directly. Should I add a lexer-type
class, and implement the multiline comments in there, or simply write in
multiline comments as a fallback when nothing else can be matched?
