This product is developed at the second-grade course, Informatic Science Basic Experiment class at the University of Tokyo.

Picrin - a lightweight scheme interpreter

Freatures

• R7RS compatibility (but partial support)
• reentrant design (all VM states are stored in single global state object)
• bytecode interpreter (based on Stack VM technology)
• direct threading VM
• exact GC (simple mark and sweep strategy)
• advanced REPL support (multi-line input, etc)

How to use it

• build

    $ make build
  

  built executable binary will be under bin/ directory.

• run

  Simply directly run the binary bin/picrin from terminal, or you can use make to execute it like this.

    $ make run
  

In the default option, when make command is called without arguments, it builds the binary and right after that dropped into the picrin interactive shell (REPL).

Requirement

picrin scheme depends on some external libraries to build the binary:

• bison
• yacc
• make
• gcc
• readline
