To avoid conflictions of inits between SRFIs and others, inits in the srfi nitro should be prefixed with srfi_. Without the convention, we may need to use generic words such as string, vector, random, array, etc. Moreover, there are SRFIs those subject is same (e.g. array may be used by SRFI 25, 47, 58 and 63). Thus, we need a clear and conflict-free naming convention. Signed-off-by: OGINO Masanori <masanori.ogino@gmail.com> |

README.md
Picrin is a lightweight R7RS scheme implementation written in pure C89. It contains a reasonably fast VM, an improved hygienic macro system, usuful 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.

Our chat room is at #picrin channel, chat.freenode.org. IRC logs here: https://botbot.me/freenode/picrin/
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.
