Fu

Fu is a simple functional language, whose name is inspired by Dr. Fu Manchu in the Sax Rohmer book series of the same name.

This language and implementation has the following goals:

• Being embeddable easily into C or C++ programs,
• Being compilable to C or LLVM,
• Having its own graph-based IR to produce high-quality executables,
• Serve as learning material for people wanting to learn about advanced compiler design,
• Progress in tandem with coding videos in which I talk about the compiler.

Building

To build Fu, just type the following commands:

meson setup builddir
cd builddir
meson compile

Planned Language Features

• Type system with first-class modules and parametric polymorphism
• Local type inference algorithm
• Partial evaluation constructs for compile-time function evaluation
