The Compositor for Windows release 0.4 is now available! 🎉 Read all about it on the blog: compositorapp.com/blog/2025-11... #TeXLaTeX

During installer testing, a problem with the FileOpenPicker came up, which I need to fix before the Compositor for Windows 0.4 release. Shouldn't take long to sort out, I hope.

The Compositor for Windows 0.4 milestone is a wrap, expect a release announcement in the next few days! 🎉 github.com/ktraunmuelle...

The new compositorapp.com website is live! 🎉 I felt compelled to update the website a little earlier than planned, because it appears I am already the target of Chinese scammers 🤡 I have thus included a corresponding warning on the new website. compositorapp.com #LaTeX

Sneak peek: The Compositor product website will get a (long overdue) refresh soon! 🎉

The next milestone of Compositor for Windows is well underway! I have just cleared one hurdle that was causing the long delays after each keystroke, and I can now focus on the automatic package downloader and installer and #WYSIWYG editing of arbitrary #LaTeX documents. github.com/ktraunmuelle...

A new public prototype of a Windows version of my previously Mac-only WYSIWYG LaTeX app Compositor is now available! Find out more on the blog: compositorapp.com/blog/2025-09... #TeXLaTeX #SwiftOnWindows

The Compositor for Windows 0.3 milestone is ready to go! 🎉 I will publish a blog post with details and installer links in the next few days. #SwiftOnWindows

If executables from debug builds of your mixed Swift/C++ project run really slow, check if you're specifying -O0 in the Swift Package manifest or CMake configuration. That makes std::map extremely slow. Use -Og instead.

With some help from @compnerd.bsky.social on the Swift forums, I now have a working Swift Testing setup integrated with CMake / VSCode / LLDB for unit-testing the Windows-specific parts of the Compositor app. github.com/ktraunmuelle... #Swift #SwiftOnWindows

I really love how well a CMake-based build setup for a Swift project works on Windows. For integration with VSCode, I've configured the default build task (Ctrl+Shift+B) to "cmake --build --preset debug", and it picks up any changes in the whole project tree. It even feels better than Xcode & SPM.

Just finished migrating the build for Compositor on Windows from Swift Package Manager to CMake (with some help from ChatGPT), consolidating the WinRT repos into a monorepo along the way. CMake is actually great! #Swift #SwiftOnWindows #CMake github.com/ktraunmuelle...

Today I am releasing the first public prototype of a Windows version of my (previously Mac-only) WYSIWYG LaTeX editor app, Compositor! Find out more on the blog: compositorapp.com/blog/2025-05... #LaTeX #TeXLaTeX #SwiftOnWindows

We are finally getting close to the Compositor on Windows 0.2 milestone! This prototype can typeset and render the bundled User Guide. The core infrastructure is in place, performance is looking good. WYSIWYG editing will be added in the next milestone. github.com/ktraunmuelle... #LaTeX #TeXLaTeX

I started working on a cross-platform source editor foundation recently (for reasons described in the ticket).

The backing store is an ASCII piece table (with line tracking), a very simple data structure that is a perfect fit for Compositor's requirements.
