Mech is for building data-driven, reactive systems like robots, games, embedded devices and more.

It simplifies data distribution, transformation, and analysis so you can focus on your project.

The following code implements FizzBuzz in Mech:

See the docs for an extended version that runs live in your browser.

Some notable features of Mech are demonstrated in this short program:

Concise Syntax: Expressive and flexible, with no need for keywords or semicolons; Mech programs are generally shorter than in other languages.
Broadcast Operations: Vector operations apply elementwise automatically, removing explicit loops and enabling efficient vectorization.
Logical Indexing: Vector elements are conditionally selected using broadcast logic operations, enabling declarative iteration and parallel execution.
Type Inference: Variable and expression types are inferred, so explicit type declarations are often unnecessary.
Immutable: Variables are immutable unless specified, promoting safer code and easier reasoning.
Rich Text: Mech programs support rich formatting and literate programming through Mechdown, a Markdown dialect.

Run Mech

There are several ways to get Mech running on your machine, which you can find in the docs. The easiest way to get started is to use the online REPL at try.mech-lang.org.

Project Roadmap

Mech v0.3 is currently beta status, meaning while many intended features are implemented and working well, other features are incomplete, not tested, or undocumented.

A Brief Roadmap:

☑️ v0.1 - proof of concept system - minimum viable language implementation
☑️ v0.2 - data specification - formulas, defining and manipulating data
📍 v0.3 - program specification - functions, modules, state machines, Mika
☐ v0.4 - system specification - tools, distributed programs, capabilities

For more details, read the ROADMAP.

Notice

Mech should be considered unstable and therefore unfit for use in critical systems until v1.0 is released.
