Hi All,
I am trying to use ANTLR for checking the return values from my Tree
grammar.
I have a simple rule which just returns the text found.
start_tree_parser walks start_parser:
"this is text" returns ["this is text"]
However, the Answer returned from this rule is the actual AST built up by
the parser,
i.e. (TEXT this is text) is the actual value returned.
The options I have in my Tree grammar are.
options {
language = Java;
output = AST;
tokenVocab = text_parser;
ASTLabelType = CommonTree;
}
And my tree grammar is as follows:
start_tree_parser returns [String result = " "] :
^(TEXT text) {$result = $text.result;}
text returns [String result = ""; ]:
(TEXTTOKEN) {$result = $text;}
The tree being formed from the parser is correct, however, I want to test
the output of walking the tree and checking the string returned.
I am not sure if I am using the correct syntax for checking the return
values. If anyone could point me in the right direction, that would be
great!
Thanks,
Kunal
