プロジェクトの歴史

The GitHub repository was created in March 2017 and describes Janet as a dynamic language and bytecode VM. The README positions it between Lua and GNU Guile: easier to embed and port than Python or Guile, richer than Lua, and distributed in a form suitable for embedding into larger programs.

Janet's core grew around a compact but batteries-included runtime: more than 600 core functions and macros, socket networking, threading, subprocesses, filesystem operations, parsing expression grammars, continuations, an event loop, Erlang-style supervision trees, a C FFI, and documentation available inside the REPL.

採用の歴史

Janet adoption is package-manager friendly because the runtime is small, scriptable, and useful without a large ecosystem install. The input package metadata records packaging across Homebrew, Alpine, Fedora, MacPorts, Nix, Scoop, winget, and openSUSE-style zypper, while Homebrew API data available during this enrichment recorded 1,057 installs over 365 days.

The project also maintains two companion ecosystem tools, Spork and JPM. The README describes Spork as a collection of utility modules and packaged scripts, while JPM is the older project manager; that split reflects Janet's use both as an embeddable runtime and as a standalone scripting language.

使われ方

Users run Janet scripts, explore with the REPL, embed the VM in C or C++ applications, or use its FFI and event-loop facilities for automation and systems tasks. The official documentation covers language syntax, special forms, data structures, fibers, modules, networking, process management, FFI, the C API, JPM, and Spork.

パッケージ好きにとっての重要性

Janet is package-nerd interesting because it packs a Lisp-like language, VM, C API, REPL, FFI, PEG engine, and async/event primitives into a small runtime package. It appeals to users who like Lua's embedding story but want macros, richer core facilities, and a Unix-scripting feel.

タイムライン

• 2017: GitHub repository created for the Janet language and VM.
• 2024: v1.36.0 release notes recorded AAPCS64 calling-convention support and REPL improvements.
• 2025: v1.40.0 release notes recorded Windows-related runtime and documentation work among many community changes.
• 2026: v1.41.2 release notes fixed a regression in out-of-bounds buffer and array indexing.

Related projects

• Janet is related to Lua, GNU Guile, Python embedding use cases, and Lisp-family scripting languages. Inside its own ecosystem, Spork and JPM are the important companion projects, and the README notes an official GitHub repository plus an actively maintained SourceHut mirror.
