[antlr-interest] Seperating Grammar and Actions..

[Anakreon Mejdi]

There is annotation-20020416.zip in the files section at yahoo.
Here is an example:

class CalcTreeWalker extends TreeParser;

expr <init>
     :   #(PLUS <p1>expr <p2>expr)   <p3>
     |   #(STAR <s1>expr <s2>expr)   <s3>
     |   <i1>INT                   <i2>
     ;

in a separate file (say file.act) you can define:
@init: code in the desired  language
@p3: some other code
call java annotation.Insert -s your_grama_file -i file.act -d output.g

output.g is parsable by antlr and has antlr code with tags replaced by 
the code defined in @init, @p3 ,...

For more information see the readme.txt file included in the archive.
