Sotlas for Visual Studio Code & Open VSX

Official extension support for the Sotlas programming language (.sotlas, .sth).

Sotlas is a modern, safe, and expressive general-purpose and systems programming language — engineered with infinite possibilities, from the lowest level (bare-metal, monolithic kernels/microkernels, drivers, and embedded systems) to high-level applications (game engines, command-line tools, network services, and desktop apps).
