<js.String 'BaseHTTPServer'> -> TypeError: obj is undefined

[jedie]

import js

modules = js.globals.vm._allModules
print modules
print dir(modules)

print modules[0]
print dir(modules[0])

output:

[object Object]
[<js.String 'BaseHTTPServer'>, <js.String 'Bastion'>, ..., <js.String 'xmlrpclib'>, <js.String 'zipfile'>]
undefined
Traceback (most recent call last):
  File "c callback", line 8, in <module>
  File "<string>", line 7, in <module>
Error: TypeError: obj is undefined

Where is my mistake?

That's a legitimate javascript error, doing undefined[0] in JS will give the same thing. The _allModules is a dict, not a list:

modules = js.globals.vm._allModules
print modules['BaseHTTPServer']

[jedie]

Hm. But not a real python dict, isn't it?

modules = js.globals.vm._allModules
print repr(modules) # -> <js.Object handle=9>

Using modules.keys() or modules.items() doesn't work. dir(modules) returns the list: [<js.String 'BaseHTTPServer'>, <js.String 'Bastion'>, ...

solution for the initial problem:

modules = js.globals.vm._allModules  
module_names = [str(m) for m in modules]
print module_names

will print:

['BaseHTTPServer', 'Bastion', 'CGIHTTPServer', 'ConfigParser', 'Cookie',...]

btw:

len(js.globals.vm._allModules) -> TypeError: 'Object' has no length

[rfk]

But not a real python dict, isn't it?

Correct; I should have said "javascript hash object", technically an instance of js.Object which is dict-like but doesn't implement all the methods of standard python dictionaries.

[rfk]

len(js.globals.vm._allModules) -> TypeError: 'Object' has no length

Unfortunately this is the expected behavior, there's no easy way to tell the number of keys in a javascript hash object.

Thanks for the information... Now i have commit with https://github.com/jedie/pypyjs/commit/53cbf2a651817cdadcb8143175fca1d6c2a31e5a a fast, complete import test... ;)

Output is:
