[il-antlr-interest: 32946] Re: [antlr-interest] ANTLR problem with .+ in tree grammar
I use the following rule for that:
genericBlock
: '{'
(genericBlock | ~('{'|'}'))*
'}'
;
Since the curly braces are inside the genericBlock rule, you'll have to modify
your componentStatement rule:
componentStatement
:'component'^ IDENT genericBlock ';'!
;

Subject: [antlr-interest] ANTLR problem with .+ in tree grammar
Hi,
I've got such a problem. I am experimenting with the ANTLR in order to
implement some kind of language later. The example below.
Grammar file (interesting part):
...
tokens{
BODY;
}
componentStatement
:'component'^ IDENT '{'! body '}'! ';'!
;
body
:.+ - BODY
;
...
tree gramar file:
...
component
: ^('component' name=IDENT body=BODY) {comp.add(new
Component($name.text, $body.text));}
;
..
What i want is to catch such a situation (for experiment purposes only):
component Foo {
anything goes here 123 :)
};
Now, I know rewrite in my example rewrites .+ to BODY it is ok. When I change
the grammar to body
:.+ - BODY
;
and tree grammar to:
component
: ^('component' name=IDENT body=(.+)) {comp.add(new
Component($name.text, $body.text));}
;
the generates Walker generates it wrong:
comp.add(new Component((name!=null?name.getText():null), b.text)); it should
have been b.getText()
How can I change files in order to catch what I want?
PS: ANTLR is great:) And Greetings to everybody :)

[il-antlr-interest: 32947] Re: [antlr-interest] ANTLRWorks Interpreter
I just downloaded ANTLRWorks and tried the example expression grammar. I type in a simple expression into the Interpreter and see the generated parse tree. Fine. I then load the SQL 2003 grammar and type in a simple Insert statement. I click the arrow and it never returns from Interpreting (Operation in progress). Can ANTLRWorks handle a more complex grammar?

[il-antlr-interest: 32948] Re: [antlr-interest] ANTLRWorks Interpreter
The interpreter is only suitable for very small grammars (without predicates!). For more complicated grammars, use ANTLRWorks' debugger instead. Regards, Bart.

[il-antlr-interest: 32949] Re: [antlr-interest] ANTLR ActionScript target broken | ANTLR 3.3 fail to compile : antlr3-maven-archetype does not exist
Since the ActionScript target is buggy, I tried to compile ANTLR 3.3.
Installed Maven, set the PATH, and followed the instructions to compile ANTLR.
While I actually can maven subproject like gunit, I fail to maven the ANTLR
folder.
I mean the main pm.xml. Get this error:
[ERROR] Child module /Users/KKK/Desktop/Neuer Ordner 4/antlr-3
2.3/antlr3-maven-archetype
of /Users/KKK/Desktop/Neuer Ordner 4/antlr-3 2.3/pom.xml does
not exist
Part of the ANTLR distribution is antlr3-maven-plugin.
Since BUILD.txt states that building ANTLR is trivial, I wonder, I forgot to
perform
a trivial step ;-)
Could someone assist?

I'd probably jump in and invest some days to reanimate the project. There are
several problems, but all seem to be small and relatively easy fixable.
Let's see. Installing the Maven Eclipse plugin right now ;-)

Subject: [antlr-interest] ANTLR ActionScript target broken
Hi,
According to these instructions, I'm trying to use ANTLR generated *.as
files in a current Flash Builder 4.5.1 project.
Therefore, I added this ANTLR's Actionscript runtime to my project -
without problems.
I compiled lexer/parser specs using ANTLRWorks without problems too.
I added the language option to the source *.g file to make ANTLR
generate Actionscript sources:
options {
backtrack = true;
memoize = true;
k=2;
output = AST;
language=ActionScript;// Added this
ASTLabelType = CommonTree;
}
Unfortunately, the ANTLR/ANTLRworks generated Actionscript code is
buggy:
Catch statements read like this catch (RecognitionException re), but
should read like this:catch ( re:RecognitionException ).
Furthermore, Flash Builder complains about the use of Array here:
public override function get tokenNames():Array { return
PhpParser.tokenNames; } Besides this, other problems exist in the
generated ActionScript sources. E.g. wrong function declaration,
package declaration inside package, ChartStream.getLine() called
instead of ChartStream.line(),...
I checked ANTLR itself too. But the pure JAR renders the same problem.
Thus, ANTLRworks isn't the problem, but ANTLR itself.
Assuming that I did everything correct, I wonder if and when the ANTLR
project may provide a bug fix.
Ah, hints how to make the current ANTLR work with ActionScript, would
be even better ;-)
Kinds regards,
S

Please send the full output and make sure you followed the instructions step by
