<h1>Introduction<a class="headerlink" href="#introduction" title="Permalink to this heading">¶</a></h1>
|
||
<p>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.</p>
|
||
<ul class="simple">
|
||
<li><p>R7RS compatible</p></li>
|
||
<li><p>Reentrant design (all VM states are stored in single global state object)</p></li>
|
||
<li><p>Bytecode interpreter</p></li>
|
||
<li><p>Direct threaded VM</p></li>
|
||
<li><p>Internal representation by nan-boxing (available only on x64)</p></li>
|
||
<li><p>Conservative call/cc implementation (VM stack and native c stack can interleave)</p></li>
|
||
<li><p>Exact GC (simple mark and sweep, partially reference count)</p></li>
|
||
<li><p>String representation by rope</p></li>
|
||
<li><p>Hygienic macro transformers (syntactic closures, explicit and implicit renaming macros)</p></li>
|
||
<li><p>Extended library syntax</p></li>
|
||
</ul>
