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

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.

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
