Jackpot - James Gosling's Latest Project

Posted by michael on from the bingo-eureka dept.

Pete Bevin writes "Artima has a fine interview with James Gosling, creator of Java, about his latest project. It's called Jackpot, and it treats the parse tree as the program. This makes refactoring much, much more intuitive. The article has some good insights into code visualization, technical writing, and making your programs more understandable."

  1. It's the Matrix! by greg_barton · · Score: 3, Funny

    So you can write what is kind of like a reverse grammar, where you associate structural patterns with what you can think of almost as TeX descriptions of how to represent the patterns graphically. What you see on the screen has been generated from this pattern matching. So we can, on a user chosen basis, turn various program structures into all kinds of visual representations.

    Why, methinks he's reinvented the Matrix. :)

    Always document your code so that a mentally retarded 6 year old can understand what you mean.

    I learned that when doing math proofs. It it wasn't written so retarded 6 year old can understand it, the TA took off marks.

    "Complexity is in many ways just evil. Complexity makes things harder to understand, harder to build, harder to debug, harder to evolve, harder to just about everything."

    So says the creator of Java. I wonder if he's bothered to browse the API lately?

    Does this mean it will be any easier for me to learn Java? Probably not. Will I ever learn Java? Of course. Let's be honest, Qweez No. Probably not.

    Hey this is my first post. I have angry half-baked opinions tho. I find that commenting for a retarded 6 year old makes code unreadable. Have you ever tried to find anything in the apache tomcat sourcecode using only notepad? Why is there a comment on "getInfo()" that says "Returns the info."??? Some classes I was trying to understand I just went through and deleted every comment so I could read the damn thing. Turns out the class was only like 12 lines of code. It was like shaving a cat.

    Oh yeah. In my ANSI Common Lisp book. Something about the real power of Lisp being that everything, including the program itself is just a tree structure.

    As a Slashdot thread on a programming language progresses, the probability of someone claiming that "Lisp already does that" approaches unity.

    Alex Stepanov famously described Java as "a money-oriented programming language". I guess that makes the name "Jackpot" an appropriate name. I suppose the next projects will be "Jingle" and "Jyp".

    It's all remiscent of my favorite programming language: intent. Unlike other programming languages which are based on strict syntax and grammatical rules, intent goes beyond what you actually type and gets what you mean, or rather, what you intend.

    Here is an example of the full source code of a compiler (filename "intend") for the intent language, written, of course in the intent language:

    write compiler for teh intent languge

    Note that despite the lack of capitalization, punctuation and proper English spelling, this will compile under the intent standard, and will produce object code which is a working intent compiler:

    [ac@/. #] intend "write compiler for teh intent languge" > intend2
    [ac@/. #] diff intend intend2
    [ac@/. #]
    Refactoring code is trivially easy, and in fact a refactorizer written in intent looks like:

    refactor the code

    This refactorizer works on all languages, just as you intend, of course. Refactoring Java is as easy as:

    [ac@/. #] intend "refactor the code" > refactor
    [ac@/. #] refactor *.java
    If simple refactoring isn't enough, you can get all of the features of Gosling's Jackpot with the code:

    write a program liek that one jackpot thing that had the slashdot storey that one time.
