forspll

forspll is an implementation of Forsp as an LLVM-based compiler. Forsp is a tiny yet very versatile programming language that mixes features of Forth and Lisp. Through LLVM, Forsp can be compiled into efficient machine code for a wide array of platforms.

forspll features:

  • Lisp-style S-expression syntax
  • Forth-style data stack for parameters/values
  • Linking with C functions (see support.c)
  • Recursion: $self gets pointer to current function

Missing features:

  • Captured variables: Functions/lambdas are not dynamic and do not capture the state of previously declared variables
  • Quote operator: quote/'
  • Built-in dynamic allocations (implement them via platform-specific support.c)

Building

Requires Clang and LLVM development files.

Run make to build the compiler.

Run make prog to compile test.fp and support.c.
