[cclib-devel] Further JSON support

[Karol L. <kar...@kn...>]

Hi,

 A clarification on my latest commit. Since I started to use a different JSON 
encoder/decoder than simplejson, I decided to add support for them in cclib.

 One of simplejson, cjson ot json is loaded dynamically when load_json() is 
called in data.py. It is only loaded once, unless an optional argument for 
the module name is passed (can be passed through read_json, etc.). An 
example:

>>> import cclib
>>> m = cclib.parser.ccopen("dvb_sp.out").parse()
(...)
>>> m.writejson(outfile="x.simplejson", module="simplejson")
>>> m.writejson(outfile="x.json", module="json")
>>> m.writejson(outfile="x.cjson", module="cjson")

This writes three files using the three different modules. So,

x.cjson is 63K
x.json is 69K
x.simplejson is 105K

I don't know if any of these modules is better or faster or if it matters, but 
since simplejson was first it is the default (being the first to try to 
load).

Cheers,
Karol
