Antlr questions

[areeda]

I am having fun with antlr and antlrWorks but getting down to the nitty-gritty I find I'm missing something.

1. How do you add antlr-runtime.jar to a module project? I've spent a fair amount of time searching with no luck.

2. How are people implementing the tokenId list? As I go through the thousands of sample files I'm finding things that weren't in the BNF description I was working from. Not a big deal really but when I add a new token do I have to regenerate the list?

Thanks,
Joe

You should make a new library wrapper module that contains the ANTLR
jar-file, and add the new ANTLR-module as a dependency.

A great resource for questions like this is the developer FAQ wiki page:
http://wiki.netbeans.org/NetBeansDeveloperFAQ

Under there look for "What is a library wrapper module and how do I use it?". That should be exactly what you are looking for.

You have to restart Netbeans for it to see the library you added...I get burned by that quite a bit.

Once you bring in your library you do need to make those jar packages public. So on your library wrapper module go to the project properties, then API versioning, and then select the packages that you want to expose. I usually just select everything.

I should also amend that you probably only need to restart Netbeans if you add more than one jar to your library wrapper module. That makes sense to because Netbeans does not know anything about jars that you add manually.

If it helps you can look at my SQLRaider project as a reference under the lib-wrapper module. As you can see I brought in quite a few dependencies.

Also be sure to do a clean build so that Netbeans picks everything up properly.

As soon as I created a module suite everything fell into place.

Believe it or not the syntax coloring seems to be working. It went through my test cases and colored them just fine.

Thanks again Jeff for the hand holding.

No problem! I'm pretty new to all this myself .

I added a wiki page with some notes on what I learned implementing the stuff in Jeff's tutorial.

Joe,

What I did was create a simple translator in ANTLR that will auto generate the appropriate syntax. I use the following syntax.


//TOKEN TYPE: keyword
{list of tokens that are keywords}


//TOKEN TYPE: operator
...


Then I copy paste the .tokens file into another text file along with the token defs from my grammar. I then run a parser that reads through the .token stuff and puts it into a hash map. Then when it goes through the token defs it looks up the token map and outputs the correct syntax for the language hierarchy class.


It is pretty simple and quick. When I get more time I want to refine it so that it will auoto generate the language hierarchy class for me using the stringtemplate engine.


When I get back to my computer I'll paste the simple grammar file for the above and an example

James,

That's the way I did it too for quite a while. It's definitely simple and quick. I went for the more extensive solution eventually because I got bored of copy-pasting the code any time I changed something in the grammar. Either way works though.
