Version 3 of ANTLR (ANother Tool for Language Recognition) created and written by Dr. Terrence Parr

Version 3 of ANTLR.

What is ANTLR?

"ANTLR, ANother Tool for Language Recognition, is a language tool that provides a framework for constructing recognizers, interpreters, compilers, and translators from grammatical descriptions containing actions in a variety of target languages. ANTLR provides excellent support for tree construction, tree walking, translation, error recovery, and error reporting. ..." -- http://www.antlr.org

Updated links

On January 24th 2013, the www.antlr.org address was changed from pointing at site for ANTLR version 3 (www.antlr3.org) to ANTLR version 4 (www.antlr4.org). So questions and answers that used www.antlr.org were correct for ANTLR 3.x before this date. The links should be updated to www.antlr3.org for ANTLR 3.x or www.antlr4.org for ATNLR 4.x.

This is my first try with cmake and I would like to have, if possible, some feedbacks about what I did since some problems remain. In the CMakeLists.txt of the library folder, I created two makefile targets: configure-antlr3c and antlr3c. The first…

Scala parser combinators vs ANTLR/Java generated parser?

I am writing an expression parser for an app written mostly in Scala. I have built AST objects in Scala, and now need to write the parser. I have heard of Scala's built-in parser combinators, and also of ANTLR3, and am wondering: which would provide…

Let's say that I want to match "beer", but don't care about case sensitivity. Currently I am defining a token to be ('b'|'B' 'e'|'E' 'e'|'E' 'r'|'R') but I have a lot of such and don't really want to handle…

Are there any LL Parser Generators for Functional Languages such as Haskell or Scala?

I've noticed a distinct lack of LL parsers that create parsers in functional languages. The ideal find for what I've been looking for without success is something to generate a Haskell parser for an ANTLR-style LL(*) grammar (modulo minor…

In ANTLR 3 you could just do the following: andExpression : (andnotExpression -> andnotExpression) (AND? a=andnotExpression -> ^(AndNode $andExpression $a))* ; Any idea how to do it in the new version?

Why are antlr3 c# parser methods private?

I'm building a parser in antlr which compiles to a working java target. When I retarget for c#2 it produces a parser in which all of the parse methods are private but marked with a [GrammarRule("rulename")] attribute. What is the approved means to…
