I\'m using ANTLR for creating a new general purpose programming language and I\'m quite happy with it.
I\'m currently developing a general-purpose agent-based programming language (its syntaxt will be somewhat inspired by Java, and we are also using object in this language).
I\'ve built my lexer and parser in ANTLR and they work really well in the sense that when user code fails to parse, it outputs useful error messages to STDERR, showing the exact line no. etc.
What is the fastest (smaller code) way to get grammar tree ? I am trying to get grammar tree. I\'ve generated C# code based on my simple grammar:
For parsing a test file I\'d like to allow identifier\'s to begin with a number. my rule is: ID:(\'a\'..\'z\' | \'A\'..\'Z\' | \'0\'..\'9\' | \'_\') (\'a\'..\'z\' | \'A\'..\'Z\' | \'0\'..\'9\' | \'_
I am new to ANTLRWorks and I am doin开发者_JAVA技巧g my final year project. Could anyone please help me in how to write ANTLR grammar just for recognising a class in java \"and printing it in any file
I am working on a project that involves transforming part of speech tagged text into an ANTLR3 AST with phrases as nodes of the AST.
I am trying to parse recursive expressions in ANTLR such as: (a + (b + C)) or ((a + b)) I read this supposed solution:
Ok... this is what I want to do..... Generate Java classes from some expression language.... Assume Step#1 is done... I have Java file. I have created JavaLaxer and JavaParser using Java.g file afte
Is there NOT logic in ANTLR? Im basically trying to negate a rule that i have and was wondering if its possible, also is there开发者_StackOverflow社区 AND logic? @larsmans already supplied the answer,
