[antlr-interest] : help :Is it possible to have line number in the AST tree node

[Anthony Brenelière]

Yes,

But, you have to create an class that inherits from the class "baseAST",
that has a 'line' property.

The default used AST is CommonAST, and does not manage lines.

Set the created AST class to the factory that creates nodes.
In C++:

ANTLR_USE_NAMESPACE(antlr)ASTFactory ast_factory( "PNode" );

Cordially,
Anthony
