Hi,

I am developing a custom script editor. I need to provide a parser for the editor. Is there any good tutorial which explains how to develop a parser from the scratch? I tried googling but none explained parser development from a newbie's prespective.
I would like to follow the AST approach. Please let me know if there is any good link which I could start with..

Thanks,
Daisy.

Hi Daisy,

I have only general recomendation to start reading at http://en.wikipedia.org/wiki/Parsing

Also there are some books on the subject, but I am not sure which is the best for you.

Regards,
Alex

Hi Alex,

Thank you for the link. I am aware of the basics of parsing. What I need to know is how we can develop a parser for a language using the AST technique. I find this link useful http://www.eclipse.org/articles/article.php?file=Article-Jav aCodeManipulation_AST/index.html but I am searching for something which goes into its details. Also, I would like to know whether using an ANTLR generated parser and lexer or a handwritten one is better?

Thanks again,
Daisy.

Hi

I think a good idea to use the ANTLR, he often used by many people, and has a lot of documentation available.

This book is very good:

There are lots of books on parsers and lots of information on google.

The "Dragon Book" is a classic reference but very hard going.

Having just written a compiler for Smalltalk (http://redline.st) and doing it first by hand and then using JavaCC my advice is to use a tool like ANTLR, JavaCC or Lex/Yacc.

Those tools mentioned above all have some form of documentation and forums to help you get started.

Good luck with your Compiler !

Rgs, James.
