Alee Forth

Still very much in development! Not suitable for real applications yet.

Alee is a portable and concise Forth implementation in modern C++. Its primary aims are for reduced program size and execution efficiency. Portability includes bare-metal platforms, with intentions to support microcontrollers with kilobytes of memory.

Compatibility

A base dictionary is being built following the "core" glossary. Progress on implementation of these words is documented in compat.txt.

A sys is available which links to a C++ function for user-defined functionality.

Building

Alee requires make and a C++17-compatible compiler.

To compile, simply run the make command. This will produce a library, libalee.a, as well as a REPL binary named alee.
A small target exists that optimizes the build for size.
