Nice! Thanks, Bob! Kevin

Yeah, it doesn't really make sense to include a dependency that doesn't get used. If there's no code in TurboGears to support doing something, there would still need to be documentation to tell users how to do that thing. And, if you're writing docs for it, you might as well add a line at the beginning that says easy_install json-py :) (But, in this case, Jeff was using json-py in core code and Bob has completely shortcircuited the need for json-py as is).

The new AjaxDataController expects all object data to arrive in JSON format. I was using json-py to parse the incoming JSON data. In keeping with the One Way To Do It, I think whatever JSON package TurboGears supports, MUST encode and decode JSON formatted data. Otherwise, developers will be forced to find an alternative solution for JSON.

OK. I wasn't aware of that. Feel free to add the json-py requirement back in (or I'll do it when I get a chance).

I'll have decoding in simple_json for 0.2. It's almost done... need to hammer out a bug or three and write real tests. -bob On Dec 25, 2005, at 8:24 AM, Kevin Dangoor wrote: OK.

[TurboGears] Re: simple_json now in use
Ok, it's done in svn with the obvious API (simple_json.loads/load), which takes an optional encoding kwarg to specify what encoding to expect input to be in. It must be an ASCII based encoding though, something like UCS-2 needs to come in as unicode because that affects more than strings. The encoder in 1.0 encodes as ASCII represented as str instances by default (using \u escapes), you can turn that off and get 0.1 behavior by passing ensure_ascii=False, which will give you either a str or unicode string as output based on the normal Python str-unicode coercion rules. I've version bumped to 1.0 because it's basically done other than future performance tweaks and maybe a bugfix or two. It's already on svn and in CheeseShop. The advantages-by-design over json-py are: 1. MIT licensed 2. Correct and fully extensible encoder 3. Correct decoder with encoding options 4. Python 2.3 support 5. Probably faster (have not benchmarked at all) The decoder does take advantage of some undocumented sre API, which binds it to sre and CPython, but that's basically an academic restriction in this context. The tests are kinda lazy and require nose. It's just a big doctest in simple_json/__init__.py. -bob On Dec 25, 2005, at 5:40 PM, Bob Ippolito wrote: I'll have decoding in simple_json for 0.2.

Thanks very much, Bob. I'll convert the AjaxDataController to use the new API.On 25 Dec, 2005, at 7:21 pm, Bob Ippolito wrote:Ok, it's done in svn with the obvious API --Jeff Watkinshttp://newburyportion.com/Democracy n: A country where the newspapers are pro-American.
[TurboGears] Re: simple_json now in use
It's also API compatible with json-py, all you have to do is change the import.. e.g.:-import json+import simple_json as jsonHowever, json-py's API is horribly named and I would recommend a refactor towards the marshal/pickle-inspired API. This is trivial: change read(s) to loads(s) and write(obj) to dumps(obj).There are, of course, load and dump for file-like objects. Technically load is currently worthless because it just does loads(f.read()), but dump actually will write in chunks which may be useful in some conditions.-bobOn Dec 25, 2005, at 9:36 PM, Jeff Watkins wrote:Thanks very much, Bob.
