I'm working on a domain-specific language (DSL) for non-programmers. Non-programmers make a lot of grammar mistakes: they misspell keywords, they don't close parentheses, they don't terminate blocks, etc.
I'm using ANTLR to generate my parser; it provides a nifty mechanism for handling RecognitionExceptions…

Hello,
I am trying to parse integers and to access their value in antlr 3.2.
I already found out how to do this in Java:
//token definition
INT : '0'..'9'+;
//rule to access token value:
start : val=INT {Integer x = Integer.valueOf( $val.text ).intValue(); }
;
... but I couldn't…

Is there anyway to use the Link Grammar or AbiSource grammar checker in PHP (or C# but I'd prefer php)? I need to have a tree structure for english sentences. Any ideas? The only things I found were in C and I can't use them on a shared host.

How would I separate the below string into its parts. What I need to separate is each < Word including the angle brackets from the rest of the string. So in the below case I would end up with several strings 1. "I have to break up with you because " 2. "< reason " (without the spaces) 3. "…

I am in need of parsing a small subset of English for one of my project, described as a context-free grammar with (1-level) feature structures (example) and I need to do it efficiently .
Right now I'm using NLTK's parser which produces the right output but is very slow. For my grammar of ~450 fairly…
