## Wren is a small, fast, class-based concurrent scripting language
|
|
|
|
Think Smalltalk in a Lua-sized package with a dash of Erlang and wrapped up in
|
|
a familiar, modern [syntax][].
|
|
|
|
:::dart
|
|
IO.print("Hello, world!")
|
|
|
|
class Wren {
|
|
flyTo(city) {
|
|
IO.print("Flying to ", city)
|
|
}
|
|
}
|
|
|
|
var adjectives = Fiber.new {
|
|
["small", "clean", "fast"].each {|word| Fiber.yield(word) }
|
|
}
|
|
|
|
while (!adjectives.isDone) IO.print(adjectives.call())
|
|
|
|
* **Wren is small.** The codebase is about [5,000 lines][src]. You can
|
|
skim the whole thing in an afternoon. It's *small*, but not *dense*. It
|
|
is readable and [lovingly-commented][nan].
|
|
|
|
* **Wren is fast.** A fast single-pass compiler to tight bytecode, and a
|
|
compact object representation help Wren [compete with other dynamic
|
|
languages][perf].
|
|
|
|
* **Wren is class-based.** There are lots of scripting languages out there,
|
|
but many have unusual or non-existent object models. Wren places
|
|
[classes][] front and center.
|
|
|
|
* **Wren is concurrent.** Lightweight [fibers][] are core to the execution
|
|
model and let you organize your program into an army of communicating
|
|
coroutines.
|
|
|
|
* **Wren is a scripting language.** Wren is intended for embedding in
|
|
applications. It has no dependencies, a small standard library,
|
|
and [an easy-to-use C API][embedding]. It compiles cleanly as C99, C++98
|
|
or anything later.
|
|
|
|
If you like the sound of this, [let's get started][started]. You can even try
|
|
it [in your browser][browser]! Excited? Well, come on and [get
|
|
involved][contribute]!
