Speaks Nim, C, Vlang, Python, and JavaScript fluently.

Coluber is a genus of non-venomous snakes known for being fast, agile, and adaptable, just like the language.

Note: Coluber is a personal hobby project born out of curiosity and a love for programming.

What is Coluber?

Coluber is a compiled, statically-typed programming language that:

Compiles to native code, supports dual-backend target: Nim (default, transpiling to C via Nim) and Vlang (experimental, transpiling to C via Vlang)

Interoperable , a single .clbr file can declare bindings to C, Nim, Python, JavaScript, and Vlang via its FFI system

Automatic memory management , delegates to the underlying backend collector (Nim's ORC/ARC or V's GC)

The compiler itself is written entirely in Nim .

Note

Vlang Backend Target (Experimental)<br>Coluber now politely offers an experimental Vlang compilation target (-b vlang or --backend vlang). This backend transpiles your .clbr code to clean Vlang code (.v), which is then compiled to a native binary.

FFI Compatibility : Under the Vlang target, FFI support is limited to C, JavaScript, and native Vlang modules. FFI bindings for Nim (.nim) and Python (.py) remain exclusive to the default Nim backend target.

Taste of the Syntax

serve name = "world"<br>constant VERSION = 1

cond first (VERSION > 0):<br>say("Hello, {name}! Welcome to Coluber.")<br>cond nothing:<br>say("Something went very wrong.")<br>public data Rectangle:<br>width: int<br>height: int<br>area: int = width * height

public task main():<br>serve r = Rectangle(width: 10, height: 20)<br>say("Area is {r.area}")<br>serve primes: list[int] = [2, 3, 5, 7, 11, 13]<br>crawl p of primes:<br>say("{p} is prime!")<br>introduce core/math task sqrt(x: float) -> float<br>introduce core/math task pow(base: float, exp: float) -> float

public task main():<br>say("sqrt(144) = {sqrt(144.0)}")<br>say("2 ^ 10 = {pow(2.0, 10.0)}")<br>introduce core/mathpy task compute_half(x: float) -> float<br>introduce core/mathnim task compute_double(x: int) -> int

public task main():<br>say("Python says half of 10 is: {compute_half(10.0)}")<br>say("Nim says double of 7 is: {compute_double(7)}")

Why Coluber?

Pain Point<br>What Coluber Does

Complex syntax<br>Indentation-based syntax, no braces or semicolons

Python performance<br>Python FFI is used selectively; core logic compiles to native code

FFI boilerplate<br>introduce path task name(args) -> type, single-line binding declaration

Garbage collector pauses<br>Uses Nim's ARC/ORC deterministic collector, which avoids stop-the-world GC

Inconsistent loop constructs<br>Two loop forms only: loop (condition-based) and crawl (iteration)

The FFI System 🔌

One of Coluber's core features is its multi-language FFI . You can link to any backend from a single source file:

use gfx/pygamecanvas alias canvas<br>introduce core/math task sqrt(x: float) -> float<br>introduce crypto/hash task hash_string(s: string) -> string alias nim_hash

public task main():<br>canvas.init(800, 600, "My...
