Current Version: 2026.1.11
Windows (x64)
For Windows 10/11 64-bit.
Download lambda-st-windows-x64.zip
Installation:
- Extract the zip file
- Add the folder to your PATH (optional)
- Run
lambda-st --versionto verify
The executable is fully self-contained - all standard libraries are embedded:
- Collections (auto-loaded)
- CLI, CodeGen, Core, Parallel, Terminal, Testing, Text, Transform (via
Module import:)
No external files required.
Linux (x64)
For Linux 64-bit (glibc 2.17+).
Download lambda-st-linux-x64.tar.gz
Installation:
tar xzf lambda-st-linux-x64.tar.gz
sudo mv lambda-st /usr/local/bin/
lambda-st --version
The executable is fully self-contained - all standard libraries are embedded. No external files required.
Standard Library Source
The standard library is embedded in the binary for single-file distribution. To extract the source files:
lambda-st dump-stdlib
This creates a stdlib/ directory containing all .st files:
- CLI.st, CodeGen.st, Core.st, FastCGI.st, Lambda.st
- Http.st, Http.Router.st, Http.Server.st, Maybe.st, Observer.st
- Parallel.st, Shell.st, Terminal.st, Testing.st, Text.st, Transform.st
- Collections.st (auto-loaded at startup)
Custom output directory:
lambda-st dump-stdlib -o /path/to/output
Overriding Embedded Libraries
During development, you can override the embedded libraries by placing files in lib/:
your-project/
├── lib/
│ └── Collections.st ← This takes priority over embedded
└── script.st
The VM searches in this order:
./lib/Collections.st(local override)- Embedded in binary (fallback)
This lets you experiment with library changes without recompiling the binary.
