Replace the generic `wrenIntBufferFind` function with a specialized `hasMethod` helper that performs exact method symbol matching in the compiler. This change removes the generic `BufferFind` macro from the buffer utility system and introduces a focused implementation in `wren_compiler.c` that directly compares method symbols using `memcmp`. The error message for duplicate methods is also simplified to exclude the module name. Additionally, a new test file `duplicate_methods.wren` is added to verify error handling for duplicate instance and static method definitions.
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.
System.print("Hello, world!")
class Wren {
flyTo(city) {
System.print("Flying to %(city)")
}
}
var adjectives = Fiber.new {
["small", "clean", "fast"].each {|word| Fiber.yield(word) }
}
while (!adjectives.isDone) System.print(adjectives.call())
-
Wren is small. The VM implementation is under 4,000 semicolons. 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.
