Re: Javascript generator
I've heard of scriptjure but never used it or looked at it. My interests took me in another direction and I've never circled back. I would be interested to know how the differ.

Re: Javascript generator
Well, taking a brief look over your code, it seems like the main difference is that scriptjure is macro-based, so all the code generation gets done at compile-time. That makes scriptjure faster, but at the expense of needing an unquote form - (clj ...) - to splice clojure expressions into the javascript source sexps. -Steve jim jim.d...@gmail.com writes: I've heard of scriptjure but never used it or looked at it.

Re: Javascript generator
I'll be glad to support it if people choose to use it and report issues. My plans to use are still on my todo list, things just keep getting put on top of them. One of which is to get my own server set up to host this and some other projects. I'll check out those asserts and make them so they're not dependent on order. Have you seen anything else that needs to be fixed? Thanks Jim --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Clojure group.

Re: Javascript generator
Cool! Rather then waiting, you could host it in the interim on GitHub or
Google Code so people like myself can submit patches (which I'm more than
willing to do) ;) Just a thought...
A couple of things:
(println
(javascript (var x)))
I would expect this to convert to:
var x;
It does not.
(println
(javascript (new Object {prop1 a prop2 b})))
var MyClass = new(ClassGenerator, {prop1:a,prop2:b});
Instead of ,
var MyClass = new ClassGenerator({prop1:a, prop2:b});
This idiom is essential to MooTools, a JS library I use quite a bit.
The other thought that I had was how to use macros with js-gen? The
javascript macro pretty much captures everything and doesn't allow macros to
be embedded. Seems like this would be quite handy.
I've been contemplating writing a system which generates tagged javascript
so that it can be sanely debugged if generated server side via Clojure.

Re: Javascript generator
Cool! Thanks.
Also sorry for the accidental double post and I had a typo, I meant the
weird result was:
(println
(javascript (new ClassGenerator {prop1 a prop2 b})))
var MyClass = new(ClassGenerator, {prop1:a,prop2:b});
Instead of-
var MyClass = new ClassGenerator({prop1:a, prop2:b});

Re: Javascript generator
One thing, there are several assertions in js-gen like the following:
(assert (= '(obj = {prop2:\str-val\,prop1:3})
(run out-str
(js-assignment '(= obj {prop1 3, prop2 str-val}) out-str
This assertion statement might fail (and did for me) since maps are not
ordered.
