Mux Code Examples

A curated collection of Mux code examples organized by category. These examples demonstrate Mux's core features with runnable, commented code.

tip

All examples on this page demonstrate real Mux language features. Feel free to copy them to the playground and modify them!

Getting Started

Hello World

Every Mux program starts with a main function. This simple example demonstrates how to print text to the console.

hello.mux

Variables and Types

Mux has explicit typing with type inference. Variables can be declared with explicit types or using auto for inferred types. Constants are declared with const.

variables.mux

Functions

Functions in Mux can have required and optional parameters. Default values are specified directly in the parameter list. Functions return values using the return keyword.

functions.mux

Control Flow

Conditionals

Mux supports if/else statements with optional else if chains. Boolean expressions work with comparison operators.

conditionals.mux

Loops

Mux supports for loops with range() and while loops. The for loop can iterate over a range with optional step.

loops.mux

Pattern Matching

The match expression is Mux's powerful pattern matching tool. It works with enums, optionals, and custom types.

pattern_matching.mux

Collections

Lists

Lists are ordered, growable collections. They support indexing, push/pop operations, and various utility methods.

lists.mux

Maps

Maps store key-value pairs. Keys and values can be any type. Access values using bracket notation or the get() method for safe access.

maps.mux

Sets

Sets are unordered collections of unique elements. They provide fast membership testing with contains().

sets.mux

Types

Enums

Enums define tagged unions with data variants. Each variant can hold different types of data.

enums.mux

Classes

Classes encapsulate data and behavior. They can implement interfaces and contain methods with access to instance data via self.

classes.mux

Generic Classes

Generics allow you to write flexible, reusable code that works with any type while maintaining type safety.

generic_stack.mux

Error Handling

Result Types

Result types represent either a successful value (ok) or an error (err). Use use when an error should propagate through a sequence, and pattern matching when both outcomes need distinct work.

results.mux

Optional Types

Optional types represent a value that might not exist. some(value) contains a value, none indicates absence.

optionals.mux

Operators

Arithmetic

Mux supports standard arithmetic operators plus exponentiation.

arithmetic.mux

Logical Operators

Boolean operators include ! (not), && (and), and || (or). They support short-circuit evaluation.

logical.mux

Comparison Operators

Compare values using standard comparison operators. All comparisons return boolean values.

comparisons.mux

References and Pointers

Reference Parameters

Functions can accept references to modify the original value or avoid copying large data.

A reference parameter is written &T, the argument is passed with &, and the value behind it is read and written through *:

references.mux

Lambda Functions

Mux supports anonymous lambda functions that can be assigned to variables and passed around.

lambdas.mux
