Chaos

Turn chaos into magic!

Chaos is a strongly typed, dynamic yet compilable, test-oriented procedural programming language that achieves zero cyclomatic complexity.

Influenced by

TypeScript's type safety
Python's syntax, modules and extensibility
JavaScript's cross-platform support
Ruby's loops and blocks, Rexx's FOREVER keyword
PHP's dedication to server-side
Haskell's pure functions
C's speed and interoperability
Go's standalone executables

Featured Aspects

There are no control structures. (no if..else, no switch..case) Decision making only possible on function returns:

 num def add(num x, num y)
     num z = x + y
 end {
     z == 8  : f1(),
     z > 10  : f2(),
     default : f3()
 }

A single unit test is enough to have 100% coverage on functions, always.
Warns you about untested functions in the executed program.
Detects possible runtime errors in compile-time.
Unique function call system that combines procedures with some aspects of functional programming paradigm.
No while or when keywords. Loops are mostly predetermined. Infinite loops can only be achievable through the INFINITE keyword.
There are break and continue statements but breaking a multiline loop inside a function is forbidden.
Single source of errors and unique exit codes for each one of them. So the errors are catchable by other programs.
Language's itself forces you to write less error-prone code.
Say goodbye to dependency conflicts with Occultist dependency manager.
Eliminated segmentation fault possibility using strict memory management and predictions.
Simplest C extension development framework so far.
