kalman, can you suggest improvements to this? I don't know exactly what it's
for.

[Haojian Wu, 2013/10/17 12:29:06]

From what I understand, this will save the binary size since we don't compile
unnecessary generated model code.

yes but there's way more than just infobars.

[Haojian Wu, 2013/10/17 00:37:58]

I search the whole chromium code and find infobars API implementation doesn't
use the generated model code. It can be disable the schema code generation at
here.

Rather than putting this here in every conditional, you can put it under the
'variables' dictionary.

[Haojian Wu, 2013/10/17 12:29:06]

Done.
