Description Javier Jardón (IRC: jjardon) 2010-06-18 01:14:09 UTC
Dasher should depend on the new a11y framework

at-spi2-core and at-spi2-atk instead at-spi

Comment 1 André Klapper 2010-07-02 13:19:00 UTC
Is it planned to work on this? It is required for GNOME3 which will be soon.
Comment 2 Patrick Welche 2010-08-18 15:19:01 UTC
Yes, I thought I would start with

(Note that dasher only uses bonobo for speech, and that at-spi2 has no cspi equivalent - so, we are well aware of what is going on, but the bug sounds more straight forward than it is - and more major than it actually is. Talking of speech: speech-dispatcher or OpenTTs anyone?)
Comment 3 André Klapper 2010-08-18 15:23:54 UTC
Currently OpenTTS, but you could ask in #a11y or on the mailing list?
Comment 4 Patrick Welche 2010-10-15 15:16:04 UTC
It seems to have changed back to SpeechDispatcher... Just in case there weren't enough moving targets, glib-dbus -> gio
Comment 5 André Klapper 2010-10-15 16:38:56 UTC
glib-dbus is not a gnome3.0 requirement.
Comment 6 6warez 2010-12-04 17:22:49 UTC
while i command dasher the following message and warnings are coming and the application starts
what is the problem and how to solve this?
please help me...

Comment 7 Alejandro Piñeiro Iglesias (IRC: infapi00) 2011-05-12 18:50:49 UTC
Patrick, you have lost some accessibility meetings, but FYI.

In relation to a C api in order to create an AT you can use libatspi. Current python bindings for at-spi2 are created using gobject introspection on this library.

It is not C-SPI compatible, but would allow to create a C AT compatible with at-spi2. So solving this issue for AT-SPI2 would involve moving to a new C API instead of a language migration.

Untested AT-SPI2 patch

I took a crack at porting dasher to at-spi2. I'm not sure what's meant by the API not being C-SPI compatible, as it seemed that most things were generally the same. That said, this patch is untested. I haven't gotten it to link, even, though everything seems to be in place.
Comment 9 André Klapper 2011-11-06 18:18:39 UTC
Could this patch get a review, please?
Comment 10 Seán de Búrca 2012-02-25 20:56:49 UTC
Any chance I could get some feedback on this patch?
Comment 11 Patrick Welche 2012-02-26 12:04:09 UTC
Could you try at least compiling and linking it first?

(In the meantime I have written at-spi2-* packages for, which have been committed a few weeks ago, so at least I have a libatspi. I am still working on removing all the various editors. After that I will write the equivalent of an external editor using libatspi. A quick look at the patch just looks like replacing old libcspi function names with libatspi...)

Updated patch with linking

The email about your comment must have gotten lost in the shuffle. I figured out the linking problem and have modified the patch accordingly. A very, very quick test seems to show it's mostly working, as far as I can tell.
Comment 13 Patrick Welche 2013-01-17 12:50:38 UTC
I have finally removed enough spaghetti to add at-spi2 support.
Comment 14 Patrick Welche 2013-01-25 17:44:32 UTC

at-spi2 support is function, in addition to Xtst and cspi.
