A simple Lisp interpreter written in C++ and inspired by this essay. The goal is to create an interpreter for Lisp that is functional enough to implement Lisp within Lisp itself.
- Linux: Download and install Clang/LLVM (Or modify the makefile as appropriate if using a different compiler frontend), bison/flex.
- macOS: Download and install bison/flex using homebrew and the Xcode command line tools.
- Windows: Download and install Clang/LLVM, MingGW-64, make, bison/flex, and add to path.
Simply run make all in the root directory of the project to build the interpreter.
We can run the built mlisp executable to launch a REPL:
$./mlisp
M-Lisp>(+ 1 1)

We can also use --single-use to read from stdin and execute directly:
$./mlisp.exe --single-use "(+ 1 (+ 1 1)) (+ 1 1)"

The full set of operator and keywords supported by M-Lisp can be found in its language specification.
