Introduction
|
|
============
|
|
|
|
Picrin is a lightweight scheme implementation intended to comply with full R7RS specification. Its code is written in pure C89 and does not require any special external libraries installed on the platform.
|
|
|
|
- R7RS compatibility
|
|
- reentrant design (all VM states are stored in single global state object)
|
|
- bytecode interpreter (based on stack VM)
|
|
- direct threaded VM
|
|
- internal representation by nan-boxing
|
|
- conservative call/cc implementation (users can freely interleave native stack with VM stack)
|
|
- exact GC (simple mark and sweep, partially reference count is used as well)
|
|
- string representation by rope data structure
|
|
- support full set hygienic macro transformers, including implicit renaming macros
|
|
- extended library syntax
|
|
- advanced REPL support (multi-line input, etc)
|
|
- tiny & portable library (all functions will be in `libpicrin.so`)
