Luma is a new programming language designed with clarity, pragmatism, and developer happiness in mind.

Born out of real-world frustrations with verbosity, rigid typing systems, and clunky error handling, Luma aims to be a clean, expressive, and fast-to-compile language — one that feels intuitive while remaining powerful and safe under the hood.

Why Luma?

Today's language ecosystem is vast — but many languages carry historical baggage, over-complicate simple tasks, or become unproductive for rapid prototyping. Some are overly academic. Others are too loose and unsafe.

Luma's mission is simple:

Readable and expressive syntax (like Python or Swift)
Optional types that integrate seamlessly (x: ?int = name.to_int())
Built-in utility functions like .to_int(), .type(), .is_type(), .to_str() — no libraries needed
Pragmatic compilation to Go, ensuring performance, portability, and easy debugging
Safe nullability using optional types instead of panics or crashes
Concise control flow and collection utilities, including built-in .walk(...) for iteration

Key Language Features

Optional Typing Done Right

You can write:

maybeNum: ?int = "123abc".to_int()

If the conversion fails, maybeNum becomes nil. No crashes. No panics. Just clear intent.

Built-in Conversions

Convert types in expressive ways:

x: int = "42".to_int()
flag: ?bool = "yes".to_bool()
pi: float = "3.14".to_float()

Each conversion supports optional fallback defaults too:

score: int = "invalid".to_int(0)

Elegant Collection Walking

Use .walk(...) -> {} on lists or ranges:

list: [int] = [1, 2, 3]
list.walk(index, value) -> {
    print("${index}: ${value}")
}

Or skip the index:

list.walk(value) -> print(value)

Built for Simplicity

Under the hood, Luma compiles to Go code.

This brings major benefits:

Leverages Go’s speed, memory safety, and concurrency
Cross-compilation and portability out-of-the-box
Zero dependency on custom virtual machines or interpreters
Easy to debug compiled code when needed

Luma avoids inventing a runtime — it piggybacks on the robust Go ecosystem while giving the developer a fresh syntax and ergonomics.

Philosophy and Design Direction

Luma is being built to solve real frustrations:

Stop repeating boilerplate — code should say what it means
Fail safely by default — no panics from failed parsing or missing keys
Be productive from day one — no giant ecosystem needed to be useful
Syntax should guide intent, not fight it
Clear type behavior, with optionality and simplicity in the type system

What’s Next?

Luma is under active development. Near-term roadmap includes:

Core language: parser, compiler, type system, built-in functions
Pattern matching support
More collection utilities (map, filter, reduce)
Improved error reporting and line tracking
REPL for quick experimentation
Package system for modularity

Try It Soon

The compiler is already working for many features — and it’s being refined daily. Very soon, Luma will be available as a CLI tool you can install and run on your machine.
