NESFab is a new programming language for creating NES games.

• The NESFab compiler (src/) is licensed under GPL 3.0 (see COPYING).
• The NESFab standard library (lib/), examples (examples/), and documentation (doc/) are licensed under the Boost Software License 1.0 (See lib/LICENSE_1_0.txt).

TL;DR: If you make a game using NESFab, your code can remain private, and you do not need to include attribution in your binary release.

Requirements:

• GCC Compiler, supporting the C++20 standard.
• Boost Library (You may also need the libboost-program-options-dev package)
• Make

NESFab can be built in either debug mode, or release mode.

• Debug mode includes runtime sanity checks to ensure the compiler is working correctly.
• Release mode has no checks and is optimized for speed.

To build in debug mode, run:

make debug

To build in release mode, run:

make release

By default, the compiler builds executables for the x86-64 architecture. To target others, specify a blank ARCH flag:

make ARCH=release

By default, the NESFab compiler builds binaries that use unofficial ("illegal") instructions. To force the compiler to only use official ones, compile the compiler with the following flag:

make ISA=legal

Post bug reports on the Github issues page and include a minimal reproducible example if possible.

When testing bugs, use the debug-mode compiler. It gives far better diagnostics.

Small fixes are welcome and can be submitted as Github pull requests. For anything larger, open a Github issue prefixed with "Contrib Request:" and what you'd like to do, and await approval before starting.

If you made a project using NESFab, please get in touch! It would be great to hear about.
