Hmm, the honest answer is that I'm not sure, as I haven't tried it that way.

[il-antlr-interest: 33893] Re: [antlr-interest] ANTLRWorks 2 (for ANTLR v4)
Ter, Just to keep adding: Refactoring No complaints on this system. It does the most common things. displaying decision DFA (well, one person mentioned to say that sometimes it gets stuck) Do you mean the syntax diagram side? I don't recall seeing it get stuck. I do, however, use the syntax diagrams constantly and find having the visualization one of the best features of using AW. Again an auto-hide like pin interface might be nice. Another feature that could be potentially helpful, although not a huge priority perhaps, would be to full screen it. That would be nice for class demonstrations. only one person mentioned showing the generated code Since it's pretty straightforward to generate the code, it's not a huge deal for me either way. group/ungroup rules, rule collapsing No real preference. Many IDEs have this and it's useful for certain kinds of boiler plate code (e.g., generated forms). IF there's a use that's helpful, it might include collapsing sections, like options/members/boilerplate stuff, or just semantic actions, or something else. I don't use this a whole lot in large scale code though in other IDEs either, though. A few other thoughts after reading your post: 1. I definitely agree that the syntax diagram, interpreter, console, and debugger are sort of odd as tabs. Having them all as pinned windows is more common in an IDE and has the advantage of letting you see more than one at a time (if you wish). 2. It might be nice if you could have (on mac) a tabbed interface for multiple grammars instead of multiple floating windows. My most common use case is switching back and forth between a tree walker and a parser. Managing multiple tabs on multiple windows is somewhat more tedious than having one window where you can click on a new file and the syntax/interpreter, etc windows auto-respond accordingly. There's a few more thoughts, for what it's worth, Stefik On Fri, Sep 2, 2011 at 12:32 PM, Andreas Stefik stef...@gmail.com wrote: On Fri, Sep 2, 2011 at 11:58 AM, Terence Parr pa...@cs.usfca.edu wrote: On Sep 1, 2011, at 1:20 PM, Andreas Stefik wrote: Debugger: I'll admit that I don't really use the debugger.

Intelligent search of grammars. Every now and then I search the grammars in the examples and grammars list to see possible ways to do something. Sometimes I don't know enough and scan everything, but other times I know that I need a predicate, cardinality, a tree conversion, lexer rule, etc. List: http://www.antlr.org/mailman/listinfo/antlr-interest Unsubscribe: http://www.antlr.org/mailman/options/antlr-interest/your-email-address -- You received this message because you are subscribed to the Google Groups il-antlr-interest group.
