Thanks again for your help up to now. Albeit your suggestion solves the problem as I stated it, I was wrong to state it the way I did. I wanted to simplify my...
I noticed that the Java engine contains constants that are not declared as final (with a note from the author not to change the values). Is this on purpose or...
When there is an error in the 'test grammar' window, and I click on the error line, the cursor in the source window is not placed over the error, so I have to...
Dear fellow GP users, I am pleased to announce ASTParser 1.0, an application that can be used to create a parser that can convert a source code file directly ...
Hello Achilleas, I think you have done some fantastic work with the AST parser. Congratulations!!! I saw your source-code and saw that you are actually writing...
Dear Pavan, The ASTParser works in a very simple way: 1. each class is linked to a rule. 2. each member of a class is linked to one of the rule's symbols. Then...
Hi Achilleas, That sounds neat. I have one question. How do you treat rules that have multiple ways of reduction. For example if: <Procedure> ::= <Type>...
Hello everyone, I am trying to write a grammar which is actually for two different languages fitted together. Based on the scope, a different lexer/parser is...
Hi Pavan, and thanks for the interest. In order to manage rules that have multiple clauses, one has two declare an empty super class, and one class that...
I added a new capability: base class member bindings. Now one can write a base class that contains all the interesting fields, and have subclasses do the...
Hello everyone, I have some parser rules which are as below (only a snippet of the complete grammar): identifier = ({Letter} | '_') ({Alphanumeric} | '_')* ...
Consider the line based log file: their arbitrary lines \n # comment \n @our structured line \n @our structured line 2 \n another of their % ^ abitrary lines ...
From what I can see you declare a terminal that contains a rule: identifier = ({Letter} | '_') ({Alphanumeric} | '_')* <integral_type> I don't know if it is...
Oh, the <integral_type> is a rule which is on the next line. I guess you mistook it as being part of the "identifier" terminal. I guess that is probably...
hello all, First of all, let me congratulate the author of this wonderful parsing system I have 1 request though, I've been working on a parser for Visual...
I have already given you the solution: terminals don't include rules, but rules include terminals. You should change your grammar to: <identifier> ::=...

Hello, I have a need to have something like .* in lex/yacc. This I believe is popularly used in parsing Comments. I was wondering how I could have it part of...
What I want is effectively like a comment, like /* ... */ Just that instead of /* it is '{' and instead of */ it is '{'. I want all the text within the braces...
