Squeak SmalltalkJoker Squeak Smalltalk : Tools Tricks Usage : prevnext Smacc AST

I am exploring the SmaCC package (using it to parse Java source 
files), but I am greatly lacking in my understanding of parsers and 
scanners.  My question is hopefully a simple one...  Once I have 
parsed or just scanned the source, what can I do with it?  There is a 
collection of SmaCCTokens returned via JavaParser class>>parse: but I 
don't know what to do with them.  They seem to be coded in some way 
but I have no idea how to interpret the codes. Does anyone have a 
short tutorial they can point me to?  The pages on the SWiki aren't 
very helpful and the tutorial on refactory.com isn't very helpful 
either.

Put code into the { }-blocks to build a abstract-syntax-tree (AST) 
from your parsed source. Unfortunately the examples coming with SmaCC 
don't do this, but actually this is the most common thing to do when 
parsing. A lot of fancy stuff can then be done by walking over the AST 
with visitors.

Have a look at the parsers and visitors that I wrote in 
SmallWiki-Parser 
(http://map1.squeakfoundation.org/sm/package/5a8df662-642d-4d2a-a093- 
5efa58780247) or

FunctionalPatternMatching 
(http://map1.squeakfoundation.org/sm/package/3772b420-ba02-4fbd-ae30- 
8eadfc323b7b) on SqueakMap. 

Hope this helps, Lukas
