Enumerate Python objects in JavaScript

Reported by Paul J. Davis | March 25th, 2009 @ 06:58 PM

I haven't gotten the "for(var f in foo)" syntax working when foo is a wrapped Python object.

    • Tag changed from python, wrapping to iterators, python, wrapping
    • State changed from “new” to “open”

    I have the initial support for iterating python objects in the JS vm. This syntax is supported:

    for(var v in obj) {
        // do something with v

    But I still have to add a check so that I can do the following syntax:

    for each(var v in obj) {
        // do something with v

    The difference being that 'for()' returns the property names (or indexes for arrays) while 'for each()' returns the value associated with each property (or array index).

    This should be fairly straightforward to add because the next() function gets passed a boolean value that indicates if it wants the name vs. the value.

    (from [fd5307a25d574ec655e41929a8a4a1be860068ca]) 'for each' iteration support in JavaScript.

    Added the 'for each(var v in obj)' semantics to iteration.

    (from [e75f991342e41d62647aa5f557eaff784598ff4b]) Fix integer property lookups.

    >>> rt = spidermonkey.Runtime()
    >>> cx = rt.new_context()
    >>> cx.add_global("bang", [2, "got me!"])
    >>> assert cx.execute("bang[1];") == "got me!"

    Thanks to spahl for the report and fix.

Python/JavaScript bridge module, making use of Mozilla's spidermonkey JavaScript implementation. Allows implementation of JavaScript classes, objects and functions in Python, and evaluation and calling of JavaScript scripts and functions respectively. Borrows heavily from Claes Jacobssen's Javascript Perl module, in turn based on Mozilla's 'PerlConnect' Perl binding.
