Community call recording The recording for the July community call is at https://youtu.be/-LIbXfuzfS0 It includes a presentation by Chris Waldon about his Arbor chat system, its Sprig Gio client and his work on implementing material design components. Viktor Ogeman also presents his ongoing work on the low-level GPU vector rendering. He's is the author of affine transformations in Gio and is working on a new renderer based on compute shaders. * Material components - https://git.sr.ht/~whereswaldon/materials * Arbor - https://arbor.chat * Sprig (Arbor GUI client) - https://git.sr.ht/~whereswaldon/sprig * Compute shaders on the CPU - https://github.com/vron/compute Loader The new widget.Loader can display an animated indeterminate loader. The Loader is simple to use and require no state: https://git.sr.ht/~eliasnaur/gio/tree/master/example/kitchen/kitchen.go#L336 Borders The widget.Border widget is useful for drawing borders around other widgets or areas. It's used the same way as layouts: https://git.sr.ht/~eliasnaur/gio/tree/master/example/kitchen/kitchen.go#L259 The widget is based on the lower level clip.Border for constructing the border outline. Native IconVG icons Gio displays icons by first converting them to images, and then transfer them to the GPU for drawing. While simple, the process is slow and memory-heavy. René Post is working on converting IconVG icons directly to Gio drawing and clipping operations: https://github.com/reactivego/ivg Font collections Nik U contributed font fallback to Gio, so missing glyphs from a primary font can be provided by secondary fonts. There's a "Hello, World" example is many languages in his repository: https://github.com/Nik-U/gioexamples/blob/master/fonts Complex script layout Supporting multiple fonts is just one step on the way to supporting layout of complex scripts such as Arabic or Hebrew. Nik also did a great deal of research to assess the options for supporting them: https://todo.sr.ht/~eliasnaur/gio/146 The main issue is that the usual library for text layout, HarfBuzz, is written in C++ and thus difficult to integrate with Gio's static binaries and minimal dependencies.
