Install CL++

Download the installer, run it, and CL++ is on your machine: the clpp compiler, editor highlighting, IntelliSense, and a language server.

Download CL++ installer for Windows

1. Save clpp-setup.exe.
2. Double-click it. The installer copies the compiler to %LOCALAPPDATA%\Programs\CLPP, adds it to your PATH, and installs the language pack in Cursor and VS Code.
3. Open a new terminal and run clpp --help.
4. Reload the editor window.

That is the full path: the site gives you the installer; the installer installs the language.

From the command line

If you already have clpp:

clpp setup

That replaces an older compiler on this machine (for example 0.1.0) with the one you just ran, then copies the matching editor pack.

Editor pack only (compiler already installed):

clpp install
clpp install --editor cursor
clpp install --editor code

From source

cargo install --path .
clpp setup

Compile a file

clpp compile examples/hello/hello.server.clpp
clpp build examples -o out
clpp fmt examples/hello/hello.server.clpp
clpp watch examples -o out

Next: Your first script.
