# 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 threaded VM
|
|
- Internal representation by Nan-Boxing
|
|
- exact GC (simple mark and sweep strategy)
|
|
- advanced REPL support (multi-line input, etc)
|
|
- tiny & portable library (all functions will be in `libpicrin.so`)
|
|
|
|
## Homepage
|
|
|
|
Currently picrin is hosted on Github. You can freely send a bug report or pull-request, and fork the repository.

## How to use it
|
|
|
|
- build
|
|
|
|
$ make build
|
|
|
|
built executable binary will be under bin/ directory and shared library `libpicrin.so` under lib/.
|
|
|
|
- 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).
|
|
|
|
- install
|
|
|
|
As of now picrin does not provide a command automatically installs the binary. If you want to place picrin library and binary in a parmanent directory, please do it by hand.
|
|
|
|
## Requirement
|
|
|
|
picrin scheme depends on some external libraries to build the binary:
|
|
|
|
- bison
|
|
- yacc
|
|
- make
|
|
- gcc
|
|
- readline
|
|
|
|
The compilation is tested only on Mac OSX. I think (or hope) it'll be ok to compile and run on other operating systems such as Linux or Windows, but there's no guarantee :(
