Picrin is a lightweight R7RS scheme implementation written in pure C89. It contains a reasonably fast VM, an improved hygienic macro system, useful contribution libraries, and simple but powerful C interface.
|
|
|
|
- R7RS compatible
|
|
- Reentrant design (all VM states are stored in single global state object)
|
|
- Bytecode interpreter
|
|
- Direct threaded VM
|
|
- Internal representation by nan-boxing (available only on x64)
|
|
- Conservative call/cc implementation (VM stack and native c stack can interleave)
|
|
- Exact GC (simple mark and sweep, partially reference count)
|
|
- String representation by rope
|
|
- Hygienic macro transformers (syntactic closures, explicit and implicit renaming macros)
|
|
- Extended library syntax

## Homepage
|
|
|
|
Currently picrin is hosted on Github. You can freely send a bug report or pull-request, and fork the repository.
|

|
## Build
|
|
|
|
Just type `make` in the project root directory. You will find an executable binary newly created at bin/ directory.
|
|
|
|
$ make
|
|
|
|
When you are building picrin on x86_64 system, PIC_NAN_BOXING flag is automatically turned on (see include/picrin/config.h for detail).
|
|
|
|
## Install
|
|
|
|
`make install` target is provided. By default it installs picrin binary into `/usr/local/bin/`.
|
|
|
|
$ make install
|
|
|
|
Since picrin does not use autoconf, if you want to specify the install directory, pass the custom path to `make` via command line argument.
|
|
|
|
$ make install prefix=/path/to/dir
|
|
|
|
## Requirement
|
|
|
|
To build Picrin Scheme from source code, some external libraries are required:
|
|
|
|
- perl
|
|
- regex.h of POSIX.1
|
|
- libedit (optional)
|
|
|
|
Make command automatically turns on optional libraries if available.
|
|
Picrin is mainly developed on Mac OS X and only tested on OS X or Ubuntu 14.04+. When you tried to run picrin on other platforms and found something was wrong with it, please send us an issue.
