Changelog

FutureBlitz 1.0.0

The first stable release, of the language, its standard library, and its tools.

The language

• Values and types: sized integers, Float and Double, Bool, Char, String, tuples, arrays, Maps, and ranges, with types inferred from values.
• Your own types: Structs, which are values, and Classes, which are references, with Properties, inheritance, Interfaces with default Methods, Enums, Operators, and Extend.
• Null safety: a type that can be Null says so, and the compiler checks it before it’s used.
• Memory: reference counting, with no garbage collector, Weak references, Defer, and leak reports in debug builds.
• Errors: Throws, Try, Catch, and Finally, and panics with stack traces of FutureBlitz’s own names and lines, in release builds too.
• Generics: generic Functions and types, constraints, inference, and defaults, compiled for each use.
• Concurrency: Spawn and Task, Parallel For, Channel, Mutex, and Atomic, Sendable and Shared Class, Async and Await, and coroutines with schedulers; the compiler stops data races between threads.
• Modules and packages: one module a file, Import and From, Public, Package, and Private, and project.toml.
• C interop: Extern blocks, @CLayout Structs, callbacks, pointers in Unsafe code, and native libraries in project.toml.
• Compile-time code: Consts, attributes, reflection, #If, and Embed.

The standard library

More than 200 modules, written in FutureBlitz and documented from their own doc comments, in twelve areas: core, collections, text, data formats, files and streams, networking and HTTP, concurrency, math, time, crypto and compression, images and the terminal, and the OS and processes. The C libraries they’re built on link in statically.

The tools

• fb: new, check, build, run, test, fmt, doc, and bindgen, and add, update, search, publish, yank, owner, login, and logout for packages.
• Builds: native executables through LLVM, linked by fb’s own lld, for Windows on x64, and macOS and Linux on x64 and arm64. Windows and Linux need no C compiler; macOS needs Apple’s Command Line Tools, for its SDK.
• The formatter: one style, with the line width the only setting.
• Tests: @Test Functions, std.test’s Expect, and doc comments’ examples run as tests.
• Docs: /// and //! doc comments in Markdown, and fb doc’s JSON of a package’s API.
• Debugging: debug info for any debugger, and VS Code debugging through CodeLLDB.
• Editors: the VS Code extension, and fb’s language server for every other editor.
• Packages: futureblitz.dev’s registry, fb.lock, other registries and mirrors, and trusted publishing from GitHub Actions.
• Installing: winget, Homebrew, apt, dnf, installers, and install scripts, on the download page.
