Hi,
Thanks a lot for your suggestion.
I have another question. I am using ParseTreeBuilder to get ParseTree,
however, I cannot get the line location of a token in original source code
by parseTree.getLine().
The results of getLine() in the parseTree and its sub-parseTree are always
zero. How can I figure it out? Thanks!
ParseTreeBuilder builder = new ParseTreeBuilder("nil");
Parser parser = new Parser(tokens,builder);
parser.compilationUnit();
TokenStream inputStream = parser.input;
ParseTree parseTree = builder.getTree();
parseTree.getLine(); ---------------------à always 0
parseTree.getChild(0).getLine();---------à always 0
I was used to analyze source code using AST, and I can precisely get the
line location of a certain token by the following codes:
Parser parser = new Parser(tokens);
parser.setTreeAdaptor(adaptor);
Parser.compilationUnit_return ret = parser.compilationUnit();
Asttree = (CommonTree) ret.getTree();
Asttree.getChild(0).getLine();---------------àcould give me the correct the
line location of the first token.
Best,
Gang

A related mail from archive:
you mean a parse tree, not AST, right? There is a ParseTreeBuilder i think.

Hey,
Is there any API in ANTLRWorks I can use to directly get the parse tree of a
sample source code?
I want to analyze the parse tree generated from Integrated Debugger in
ANTLRWorks. Is there any API in the ANTLRWorks for this goal? Thanks a lot!
Best,
Gang
