The `signatureSymbol` function previously built a method name string as a side effect before hashing it. This change separates the stringification logic into a new `signatureToString` function that writes the full signature name into a provided buffer and updates its length. All callers now use the new helper, making the code clearer and allowing the stringified signature to be reused independently of symbol lookup.
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.
IO.print("Hello, world!")
class Wren {
flyTo(city) {
IO.print("Flying to ", city)
}
}
var adjectives = new Fiber {
["small", "clean", "fast"].map {|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.
If you like the sound of this, give it a try! Even better, you can contribute to Wren itself.
