Re: [orca-list] Pluginsystem for Orca using libpeas

Does macOS/iOS even give you the API access to write your own screen readers?
I've heard so much complaining about VoiceOver on both, that it seems like we'd have other screen readers if it was possible. There are several on Android, multiple on Windows, and at least were multiple Linux screen readers if anyone here remembers Gnopernicus. :)

Hi Christopher,

I wasn’t meaning to ask if you could do this work, just trying tu gauge how possible such an endeavour would 
be before sticking a few devs on it. We are particularly interested in an alternate Mac screen reader in 
addition to Linux support. :)

Warm regards,
Alex

My understanding is that a lot of screen reader code is taking advantage of technologies built into and 
unique to each operating system, so only a limited amount of the code could be ported, and a lot of work 
would have to go into making this portable code work with the OS specific layers that would be needed on each 
platform. Just my $0.02.

Howdy Alex,

maybe its technically possible, but windows already has a lot of screen readers. So i will only concentrate 
my time to Linux. For windows its just another alternative. fur Linux its a must have without any choice 
currently.

Hi All,

I’m just throwing this out there but can this work set the stage for Orca to be ported to other operating 
systems? The organization I work with is interested in cross-platform screen reader technologies. If there 
are already separate plugins for GTK and QT apps on the table, could this pave the way for plugins based on 
MSAA or Apple’s AXAccessibility APIs?

Warm regards,
Alex

Hi,

I would go for: 3. Build libpeas from source.

Make a package for it just took 40 seconds on my laptop.

I'll leave for others to tell you how to do that for Ubuntu.

Cheers,
Didier

if this commit is true, you need at least version 1.26 of libpeas from January 2020.

Debian Bullseye (the next release) has libpeas 1.28.
Unfortunately, it doesn't appear to be in buster-backports.
I looked at the version in Bullseye. It actually has fewer dependencies than the version in Buster, and many 
of them are the same version or are covered by packages in Buster.
However, it depends on libpython3.9, and as the version of Python in Buster is 3.7.3 and one of the dependencies 
for libpython3.9 is libc6 >= 2.29 which is higher than the version in Buster, trying to pull in libpeas from 
Bullseye will result in an upgrade of libc6 which will suck in a whole lot of other packages.
As I see it, your choices are:
1.  Upgrade to Bullseye.  Bullseye is currently frozen and is likely to release soon, so this might be safe 
enough to do.  I'm going to do this on one of my systems for a similar reason - I need Python > 3.7.  You 
should read the release notes first though as there may be important changes (you should do this anyway).
2.  Pull in libpeas from Bullseye anyway and accept all the upgraded packages.  This will result in a 
partially upgraded system which is probably not a good idea, especially given that lib6 will be upgraded.
3.  Build libpeas from source. I have no idea at all how involved this is and it may well be more work than 
it's worth, particularly given the dependencies.
4.  Wait for Bullseye to release.
HTH,
Geoff.
