SLS is a statically-typed, stack-based language with pure postfix notation combining the execution model of HP's RPL, the type system of C and Rust, and modern array operations from Uiua.

Build Commands

Linux

C

cd SLS_C
python3 build.py build
./bin/sls

Python run module

cd SLS_Python
python3 -m sls_py
python3 -m sls_py.calc

Python Setup

cd SLS_Python
python -m venv .venv
source .venv/bin/activate
pip install build wheel "setuptools>=61.0"
pip install -e sls_build_backend

Python build module

cd SLS_Python
source .venv/bin/activate
python3 -m build --no-isolation
pip install ./dist/sls_python-0.0.2a0-py3-none-any.whl
python3 -m sls_py
python3 -m sls_py.calc

Rust

cd SLS_Rust/sls
cargo build
./target/debug/sls_rs

Windows

C (Using Visual Studio Developer PowerShell)

cd SLS_C
python build.py build
.\bin\sls.exe

Python run module

cd SLS_Python
python -m sls_py
python -m sls_py.calc

Python Setup

cd SLS_Python
python -m venv .venv
.venv\Scripts\activate.bat
pip install build wheel "setuptools>=61.0"
pip install -e sls_build_backend

Python build module

cd SLS_Python
.venv\Scripts\activate.bat
python -m build --no-isolation
pip install .\dist\sls_python-0.0.2a0-py3-none-any.whl
python -m sls_py
python -m sls_py.calc

Rust

cd SLS_Rust\sls
cargo build
.\target\debug\sls_rs.exe

MacOS

Reference Linux build instructions.

For C there is the python3 build.py macos command, but it is untested as I didn't test it on a Mac. I also don't know if python3 build.py build would also work on a Mac.

Python and Rust should just be the same or similar to Linux.

RP2040

Only tested on Linux. Only SLS_C supports RP2040.

Install Pico SDK to ~/pico/pico-sdk, or set environment variable PICO_SDK_PATH to your installation path. You will also need to install the appropriate compiler.

Debian GNU/Linux

sudo apt install gcc-arm-none-eabi

cd SLS_C
python3 build.py rp2040
