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

Howdy Andy,
i assume, the idea is to keep the orca API what is exposed to the Plugins very similar to NVDA one. in that way plugins could been very easy to port over. do i unerstand right, you would implement the usage of 2 different APIs in an plugin? i dont think this is a way to go as we cant force authors to do so. 

cheers chrys

Considering that Orca and NVDA are both written in Python 3, this concept of sharing addons between Orca/NVDA 
might be possible. The only trick is determining what screen reader is involved, then enabling/disabling the 
API for each one. When I get up and running, will take a look.

Howdy Alex,

This is an very good idea. I thought about something similar. Sadly, I do not have many experience with NVDAs 
API. Maybe Andy can help out here? As far as i understand he already did some nice additions for NVDA.

@Andy, maybe can create some level of compatibility? Maybe use the good, and improve the not so good concepts 
of NVDA in some compatible way?

Cheers chrys

Hi,

Then, let me propose something different. What if we made a common plugin format with NVDA, Orca, and others, 
os that plugins can be written once and shared. Like web browser extension, they would not be 100% portable, 
but could hire enough code to push the industry forward and give greater choice to users, leading to a bigger 
pool for developers.

Warm regards,
Alex

Howdy Alex,

well, possible is very unsharp by definition . Technically is everything possible. Depends on how many 
developers, time or money is spent. So the right question is does it make sense? It agree to Christopher, a 
lot of abstraction is required, and the backend scrips might need a complete rewrite on every Platt-form as 
well. even if possible, i would say its not wort to do. In that time you have created something from scratch 
as well and this fitts the needs even more. Just my opinion, not  a rule ;).

Cheers chrys

Yes, I understand. My point is that I don't think it's very feasible, but that's just my $0.02.

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.
