[g-a-devel] CSPI finally dropped, use libatspi instead

[Piñeiro <apinheiro igalia com>]

Hi,

Just sharing with all the people one of the conclusions of the last 
meeting (minutes not available yet).

Some months ago Mike Gorse changed how python at-spi2 bindings are 
created, so now there is a core C library called libatspi, and pyatspi2 
is created based on gobject introspection.

That means that now we have a library based on C to access at-spi2 
(thanks Mike). So if anyone want to create a C AT, in theory he can use 
libatspi.

*But*, libatspi is not fully API compatible with CSPI. Mike proposed 
that it could be possible to create a intermediate compatibility layer. 
But we concluded that it doesn't worth.

That means that any existing C-SPI based app that wants to be compatible 
with at-spi2, needs to be migrated to libatspi, so it is possible that 
this "doesn't worth" is wrong, but for the moment this is the current plan.

In related news:
  * As it is based on gobject introspection, Joseph will investigate if 
it is possible to call those methods using javascript. We already call 
atk methods on gnome-shell, so we are positive on it.
  * Status of libatspi documentation is not enough (IMHO) to ask upload 
it to http://developer.gnome.org/references. We'll try to sort it soon.
  * CCed Patrick, as Dasher migration to work with at-spi2 is still 
pending, we hope that this would help.
  * CCed Eitan, as on his last work with Caribou, he is moving some 
parts of Caribou to C
