This is a fork of https://github.com/i3/i3/ where I have migrated the sourcecode from C to C++23 just for fun.

I have experimented with the following:

• Converted the source code from C to C++23
• Used C++20 modules
• Played around with ANTLR4 to parse the configuration file
• Use XPP as a wrapper for XCB
• Used GMock and GTest for mocking and unittests
• Conan2 as a dependency manager
• CMake + ninja as a build system

It builds (on my machine) with a minor patch to libev (its broken when used in conjunction with C++20 modules) with clang 18 and Cmake 3.28.3
