XS

v1.2.26A programming language. Anywhere, anytime, by anyone.One statically-linked binary contains the compiler, the language server, the debugger, the formatter, the linter, the test runner, the profiler, and the package manager. The same source runs unchanged on Linux, macOS, Windows, WASI, iOS, Android, ESP32, and Raspberry Pi.6backends3transpile targets0runtime deps2.9MB binaryhero.xsmacOS, Linux$curl -fsSL xslang.org/install | sh|Windows>irm xslang.org/install.ps1 | iexSource$git clone github.com/xs-lang0/xs && cd xs && makeBoth installers verify the GitHub release against its published SHA-256 sums before running anything.
