I think you could even just inline the whole of api_features in here.

        if platform in api['platforms'])

Hm, so, how about we change the way this works.
- do away with 'chrome' and 'experimental'. just have 'stable', 'beta', 'dev',
'trunk', and 'experimental'  at the top level.
- factor templates accordingly.

[hukun, 2013/11/04 11:07:26]

This is a little big change, I guess it will influence some other pages. Could I
use another CL to make this change?

[not at google - send to devlin, 2013/11/04 18:30:49]

Sure.

if category in ('chrome', 'experimental'):

though I might just implement this in an else: clause.

[hukun, 2013/11/04 11:07:26]

Do you mean put "private apis" here, then put "chrome,experiment" in else
clause?

[not at google - send to devlin, 2013/11/04 18:30:49]

Yes

[not at google - send to devlin, 2013/11/02 00:31:48]

when is there not a model? there should always be a model...

[hukun, 2013/11/04 11:07:26]

For some private api, e.g. extension.sendNativeMessage. There is no model.

[not at google - send to devlin, 2013/11/04 18:30:49]

Ah right. Yes, I just fixed a bug for that in APIModels. You should be able to
list models with APIModels.GetNames() which will filter out things like
"extension.sendNativeMethod"; and then GetModel should never return None.

[not at google - send to devlin, 2013/11/02 00:31:48]

why do you need this? an empty list would be simpler I think.

[hukun, 2013/11/04 11:07:26]

I used this to check if there is some data in template language. According to
handlebar,null is never considered a value. Is there someway to check the length
of list in handlebar template? I did not find out it, so I just use null to
stand for "false".

[not at google - send to devlin, 2013/11/04 18:30:49]

{{?empty_list}} should be false (same as None/False).

See here:
https://github.com/kalman/templates/blob/master/python/handlebar.py#L571

The documentation itself may be a little out of date; the source code is a
better reference (even better is the source code that's actually checked into
Chromium; the version there is a little newer).

you could do just all_apis.sort(key=itemgetter('name')). however, I'd just
inline it:

  'all_apis': sorted(all_apis, key=itemgetter('name')),
  'private': sorted(all_apis, key=itemgetter('name')),
