ValueError: Expecting , delimiter #3

I've been trying to convert this multi-line CSON to JSON. The CSON used in the example is a snippet for Atom editor. Since Atom lints all snippets in use on startup, I don't think there's anything wrong with it.

>>> cson = """
... '.text.html':
...   'cc-by':
...     'prefix': 'cc-by'
...     'body': '<${1:i} class="cc cc-by$2"></${1:i}>'
...   'cc-cc':
...     'prefix': 'cc-cc'
...     'body': '<${1:i} class="cc cc-cc$2"></${1:i}>'
... """
>>> cson.loads(cson)

Oddly enough, the same error occurs when using python-cson instead. Any ideas?

I assume it it a copy-paste error, since you override cson module with the string (i.e. in cson.loads(cson), you mention cson twice). In any case, the following works for me.

>>> import cson
>>> t = """
... '.text.html':
...   'cc-by':
...     'prefix': 'cc-by'
...     'body': '<${1:i} class="cc cc-by$2"></${1:i}>'
...   'cc-cc':
...     'prefix': 'cc-cc'
...     'body': '<${1:i} class="cc cc-cc$2"></${1:i}>'
... """
>>> cson.loads(t)
{u'.text.html': {u'cc-cc': {u'body': u'<${1:i} class="cc cc-cc$2"></${1:i}>', u'prefix': u'cc-cc'}, u'cc-by': {u'body': u'<${1:i} class="cc cc-by$2"></${1:i}>', u'prefix': u'cc-by'}}}

If it doesn't for you, please update the cson package and if it doesn't help, post the exact error here and I'll look into it further.

No, I only renamed my variable for this issue and didn't think of the conflicting name. Here's the full log:

>>> import cson
>>> t = """
... '.text.html':
...   'cc-by':
...     'prefix': 'cc-by'
...     'body': '<${1:i} class="cc cc-by$2"></${1:i}>'
...   'cc-cc':
...     'prefix': 'cc-cc'
...     'body': '<${1:i} class="cc cc-cc$2"></${1:i}>'
... """
>>> cson.loads(t)

Obviously, it's importing the wrong package. Sorry!

Ok, good. Note that python-cson does not actually parse Coffescript, but rather some weird extension of JSON. You should probably steer clear of it.

Let me know if I can help you further.
