Re: Segfault when trying to run example 5 hours ago

From Chris Waldon to ~eliasnaur/gio

Hi Yaroslav,

I've never seen this error before in Gio. My suspicion is that it's
originating from the Artix Linux GL libraries that Gio is calling
into. I run a lot of Gio applications on Arch, and I can confirm that
this doesn't happen there.

You could try booting a live distribution for a different distro and
running it there as a sanity check. If you're looking to go deep and
debug this problem, I recommend attaching gdb to the built Gio program
and issuing `backtrace` after the segfault to try to find where in the
C library you're hitting the problem.

The ML is a good place for this until we better understand the

Arbor Virtual Retreat is starting soon! 2 days ago

From Chris Waldon to ~whereswaldon/arbor-announce

Hey all,

The retreat starts at 9:00am EDT (13:00 UTC)! You can join here:

https://meet.nixnet.services/b/chr-mdt-z3m

Our rough agenda (EDT times):

- 9am-12pm: divide into teams, choose a project, and start hacking away at it
- 12pm-2pm: social time for grabbing food, playing games, introducing
pets, etc...
- 2pm-4pm: more hacking time with your team
- 4pm-6pm: another social break for food and such
- 6pm-9pm: final hacking session with your team.

Re: trying to make an iOS GIO app problem 3 days ago

Hmm. This error reads to me as "I couldn't find this string within
this list of one string". I do not know off the top of my head why
this isn't working. I would recommend attaching a debugger to gogio
and watching it try to choose the provisioning profile. You will
probably be able to determine why it doesn't recognize that profile by
seeing where and how it concludes that no profiles match.

Re: Creating an iOS application 4 days ago

From Chris Waldon to ~eliasnaur/gio

Hi Christophe,

> I registered on the developer.apple.com site and didn’t see how to register a bundle id. It seam that we are required to subscribe to developer membership thing which cost 100USD per year to be able to create a bundle id on the web site.

I believe that it is _possible_ to run an app on your local iDevice
without paying the $100 fee, but you won't be able to distribute it.
This isn't the route that I went down though, so I'm not certain of
the details. I think everything you need can be done in XCode.

You could try this tutorial [0]. It's 5 years old, so things have
probably changed a little bit, but I suspect that the same general
workflow is still possible. Try to deploy just an iOS app (X-code or
swift new blank app project) to your phone by following the tutorial.
If you can make that work, try using the same bundle id in gogio.

I've done this process for sprig [0], and I can confirm Matt's point.
I don't have a step-by-step guide either (and it was sometime last
year, so I'm fuzzy), but you basically create a bundle identifier on
their site, then create a provisioning profile that is intended to
publish apps with that bundle id.

Jack Mordaunt and I talked about them during the last communit call,

This is currently true.

Re: Support for "CustomEvents" and "Addons" 8 days ago

From Chris Waldon to ~eliasnaur/gio

I think something like this could be very useful. I don't especially
want Gio's event router choked with application-level events, but I
think it makes a lot of sense to expose platform events like the
gyroscope or haptic feedback as events and operations similar to the
clipboard. I think it comes down to whether or not we can create this
extensibility without over-complicating the existing code to achieve
it.

Elias, do you think there's room to create this kind of extensibility
for other hardware/input event types?

Cheers,
Chris

Arbor Sync is on for today (sorry for the short notice) 11 days ago

From Chris Waldon to ~whereswaldon/arbor-announce

Hey all,

I just realized that I forgot to send the usual announcement email
this week, but we ARE syncing tonight. I forgot because I was too busy
working on the new features that just dropped in sprig v0.0.18-rc3. I
hope you get a chance to try them soon!

Anyway, you can join our meeting at 7pm EDT (23:00 UTC) here:
https://meet.nixnet.services/b/chr-mdt-z3m

We'll take notes in here: https://pad.nixnet.services/XBw6jJwVS0-uM25r9thmHw#

I hope I'll see you there!
