<p>Think Smalltalk in a Lua-sized package with a dash of Erlang and wrapped up in
|
|
a familiar, modern <a href="syntax.html">syntax</a>.</p>

<p><strong>Wren is small.</strong> The VM implementation is under <a href="https://github.com/wren-lang/wren/tree/main/src">4,000 semicolons</a>.
|
|
You can skim the whole thing in an afternoon. It’s <em>small</em>, but not
|
|
<em>dense</em>. It is readable and <a href="https://github.com/wren-lang/wren/blob/46c1ba92492e9257aba6418403161072d640cb29/src/wren_value.h#L378-L433">lovingly-commented</a>.</p>
|
|
</li>
|
|
<li>
|
|
<p><strong>Wren is fast.</strong> A fast single-pass compiler to tight bytecode, and a
|
|
compact object representation help Wren <a href="performance.html">compete with other dynamic
|
|
languages</a>.</p>
|
|
</li>
|
|
<li>
|
|
<p><strong>Wren is class-based.</strong> There are lots of scripting languages out there,
|
|
but many have unusual or non-existent object models. Wren places
|
|
<a href="classes.html">classes</a> front and center.</p>
|
|
</li>
|
|
<li>
|
|
<p><strong>Wren is concurrent.</strong> Lightweight <a href="concurrency.html">fibers</a> are core to the execution
|
|
model and let you organize your program into a flock of communicating
|
|
coroutines.</p>
|
|
</li>
|
|
<li>
|
|
<p><strong>Wren is a scripting language.</strong> Wren is intended for embedding in
|
|
applications. It has no dependencies, a small standard library,
|
|
and <a href="embedding">an easy-to-use C API</a>. It compiles cleanly as C99, C++98
|
|
or anything later.</p>
|
|
