I’m the author/maintainer of Sysprof. I took over maintainership from Søren Sandmann Pedersen years ago so we could integrate it with GNOME Builder. In the process we really expanded it’s use cases beyond just being a sampling profiler. It is a system-wide profiler that makes it very easy to see what is going on and … Continue reading Frame pointers and other practical near-term solutions
I added a bunch of examples to help refine some of the libdex APIs. Additionally, I added support for the Windows Fibers API which brings our support matrix up to Linux, macOS, FreeBSD (possibly some other BSDs too), Illumos, Hurd, and now Windows. I know there are a few things I’d like to still add … Continue reading Fiber examples and Windows support
Previously on Futures, Work-Stealing, and such. One thing I admired during the early days of Python Twisted was how it took advantage of the language to write asynchronous code which read as synchronous. Pretty much all the modern languages now have some form of this in stackless or stackfull form. C has been able to … Continue reading Threading Fibers
Around 15 years ago I worked on some interesting pieces of software which are unfortunately still not part of my daily toolbox in GNOME and GTK programming. At the time, the world was going through changes to how we would write thread pools, particularly with regards to wait-free programming and thread-pooling. New trends like work-stealing … Continue reading Concurrency, Parallelism, I/O Scheduling, Thread Pooling, and Work-Stealing
Some of the first abstractions we made when creating GNOME Builder are now available to everyone in GObject! In particular, writing Text Editors requires tracking lots of information and changes from various sources. Sometimes those changes come from 2nd-degree objects via the object you really care about. For example, with a GtkTextView that might mean … Continue reading GSignalGroup and GBindingGroup
One of the things we spent some time on early with Builder was creating built-in VIM emulation. Originally it was written in C, but then got converted to this nasty CSS for a couple of reasons. First, that keybindings in GTK 3 were largely done with CSS due to how we moved away from gtkrc … Continue reading GtkSourceView is getting a VIM emulator
One of the last features from Builder I really wanted to get upstream for the 5.0 release (and the beginning of a new ABI stream) is our auto-indenter interface. It, however, was a product of the times in GTK 3 and was rather clunky by necessity. Now that we are on GTK 4, I could … Continue reading Auto-indenters for GtkSourceView
During the past years (and especially last cycle) I’ve worked to push a number of features upstream from Builder into GtkSourceView. Not only does this improve the ecosystem for all applications, but it reduces the number of things we need to maintain downstream in Builder as we move to GTK 4. That included a new … Continue reading GtkSourceView Interactive Tooltips
It started as an application for me to verify the correctness of the GtkSourceView 5 API (which targets GTK 4). After that it helped me implement JIT support for GtkSourceView languages. Once that was done it became my test case while I wrote the GTK 4 macOS backend and revamped the GL renderer. It is … Continue reading A GTK 4 based Text Editor
Earlier this year I started a branch to track GTK 4 development which is targeted for release by end-of-year. I just merged it which means that our recently released gtksourceview-4-8 branch is going to be our LTS for GTK 3. As you might remember from the previous maintainer, GtkSourceView 4.x is the continuation of the … Continue reading GtkSourceView Next
