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 by working through the "core" and "core extension" glossaries. These word lists are included in compat.txt, with "yes" indicating that the word is implemented either in core.fth or within Alee itself.

A sys word is available to provide access to user-defined C++ functions.

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.
