[Dri-devel] DRI configuration progress

[Felix <fx...@gm...>]

Hi,

I have the libGL part working now. I also wrote a small xdriinfo program
as described in the design doc. Now I'm working on some Python code that
uses xdriinfo for getting dri configuration information. While writing a
parser for the dri configuration information in Python (using Python's
expat bindings) I came across two issues:

1. There should one element around all <section>...</section> elements
   in order to make the whole thing a well formed XML document.

2. Negative numbers in ranges are a bit ugly. E.g.:

   <option name="foo" type="float" default="-1" valid="-1.5--0.5"/>

There is no ambiguity with 2. It just makes the parser a bit more
complicated (at least in Python) and it is a bit hard to read. You had
suggested to use ".." instead of "-" before. But then you'd have to be
careful not to confuse this with decimal points. What about using ":"
instead?

   <option name="foo" type="float" default="-1" valid="-1.5:-0.5"/>

or with multiple ranges:

   <option name="foo" type="float" default="-1" valid="-1.5:-0.5,0.5:1.5"/>

One more thing, I'd like to rename driConfigOptions to
__driConfigOptions. This matches the naming convention of
__driCreateScreen which is also obtained using dlsym in libGL.

Regards,
  Felix
