^title Welcome
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. You can skim the whole thing in an afternoon. It's small, but not dense. It is readable and lovingly-commented.
-
Wren is fast. A fast single-pass compiler to tight bytecode, and a compact object representation help Wren compete with other dynamic languages.
-
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. It compiles cleanly as C99, C++98 or anything later.
