[il-antlr-interest: 32988] [antlr-interest] rule parameter question
Hello,
I am trying to do what I think is a simple parameter passing to a rule in
Antlr 3.3:
---
grammar rule_params;
options
{
output = AST;
}
rule_params
: outer;
outer: outer_id '[' inner[$outer_id.tree] ']';
inner[CommonTree parent]: inner_id '[' ']';
outer_id: '#'! ID;
inner_id: '$'! ID ;
ID : ('a'..'z' | 'A'..'Z') ('a'..'z' | 'A'..'Z' | '0'..'9' | '_' )* ;
-
However the inner[CommonTree parent] generates the following:
*** inner4=inner((outer_id2!=null?((Object)outer_id2.tree):null));
Resulting in this error:
*** The method inner(CommonTree) in the type rule_paramsParser is not
applicable for the arguments (Object)
As best I can tell, this is the exact same as the example in the Antrl
book:
classDefinition[CommonTree mod]
(Kindle Location 3993) - sorry I don't know the page number but it is
in the middle of the book in chapter 9, section labeled Creating Nodes
with Arbitrary Actions.
Thanks for any help.

Hi Mark,
I presume you didn't see my answer on Stackoverflow:

If you did, is there anything that wasn't clear?

Good to hear it worked.

[il-antlr-interest: 32992] Re: [antlr-interest] rule parameter question
Just for the record, in case someone stumbles upon this post, the answer
from SO:
-
If you don't explicitly specify the tree to be used in your grammar,
.tree (which
is short forgetTree()) will return a java.lang.Object and a CommonTree will
be used as default Treeimplementation. To avoid casting, set the type of
tree in your options { ... } section:
options
{
output=AST;
ASTLabelType=CommonTree;
}

[il-antlr-interest: 32997] [antlr-interest] Ignore Mismatched input and No viable alternative
Hi all, I'm trying to parse a text file created by an application. There are lines in this text file that I know perfectly their contents and format, and these lines are correctly parsed. Otherwise, there are lines that can be recognized by any syntax I can think about. When I parse the file with my syntax, I'm getting several occurrences of Mismatched input and No viable alternative on the lines that I can't recognize. What I want is simply throw away these invalid lines, as if them would be absent from the text file. For my purposes, these lines are invisibles. How can I do that, ignoring the lexer/parser errors?

Perhaps, but Nilo is talking about discarding complete lines. Chances are that somewhere in these ignored-lines, text exists that looks like a token that _do_ need to be kept.

[il-antlr-interest: 33002] [antlr-interest] RES: Ignore Mismatched input and No viable alternative
Bart is right... I need to discard complete lines and not just some unrecognized tokens. And really exists recognized tokens on lines I want to discard, 'cause these tokens are in invalid places on the line... I'm thinking in change the text file format, putting a discard token on the beginning of the lines I want to discard (something like a comment line), but these will take a little more time...
