    Documentation

    FutureBlitz 0.1.0's docs: guides by topic, the language's spec, and the references for fb, project.toml, and the standard library.

    New to FutureBlitz? The tour comes first. Each guide's examples are whole programs, built and run with fb when the site was built.

    Guides

    Coming from Blitz3D

    What stayed from Blitz3D, what changed and why, and how a .bb program's parts are written in FutureBlitz.

    Types and nullability

    The built-in types, conversions, aliases, Enums, and how T? keeps Null where it's written.

    Classes and Structs

    Values and objects, constructors, Destroy, Properties, Statics, Operators, Extend, and visibility.

    Errors

    Checked errors with Throws, Try and Catch, Finally and Defer, and panics with stack traces.

    Generics and Interfaces

    Interfaces with defaults, the built-in ones, generic Functions and types, constraints, and Where.

    Concurrency and async

    The worker pool, Spawn and Tasks, Parallel For, Channels, Mutex and Atomic, Sendable, and coroutines.

    Modules and packages

    Modules and Import, visibility, project.toml, local dependencies, libraries, and native libraries.

    C libraries and bindgen

    Extern blocks, the C types, @CLayout Structs, strings, callbacks, Unsafe, and fb bindgen.

    Testing

    @Test Functions, Expect and ExpectThrows, fb test, tests/ folders, and doc tests.

    Release builds and shipping

    Debug and release builds, what an executable needs beside it, stack traces, licenses, and formatting.

    Reference

    The fb command

    Every command of fb's, with its options, as fb help gives them.

    project.toml

    Every key of a package's manifest, from spec chapter 11.

    The standard library

    Every module of std's, from its own doc comments.

    The language spec

    The specification is the language's source of truth, written for the compiler's builders as much as its users; its examples are close to FutureBlitz but not all whole programs.
