[antlr-interest] some questions about antlr

[Bharath Sundararaman]

Hi Yolanda,

Did you check this page: http://www.antlr.org/grammar/list?
 

>> What is antlr tranlation of the following PCCTS rule: (IF YOU ARE ASKING
WHAT THIS MEANS, HERE IS A SIMPLE EXPLANATION).

This is a rule (in the parser) that would recognize a "block of statements"
in your input, which start with an openBracket, contains statements and ends
with a closeBracket.

Assume that openBracket is a left curly "{", closeBracket is a right curly
"}", colon is obviously ":", variableName is an identifier and verticalBar
is "|". If "a:=10;" can be considered as a statement, then your "block" rule
would recognize the code fragment below:

{ // Open bracket
	:myVariable // This is your identifier.
	|  // Vertical bar
	a:=10;
	b:=20; // Statements
}// Close bracket

The # symbol is for the abstract syntax tree, which gets generated if you
set the buildAST option to true. For this code to work, you must have other
rules that take care of whitespace, newlines, tabs and single line comments.


Bharath.

Hello,

 I have some problems with antlr and I hope you could help me:

1- I need antlr .g extension file for smalltalk-80. Where could I find it?
2- What is antlr tranlation of the following PCCTS rule: 
     block :
	  openBracket #{ ( colon variableName )+ verticalBar } statements
closeBracket
	;

Thank you,

Yolanda
