In package-manager practice, it is most historically tied to Haxe, which supported compilation to Neko bytecode before HashLink became the preferred successor target. ### プロジェクトの歴史 The Neko website says it was developed as part of Motion-Twin's research and development work on better languages by Nicolas Cannasse. The same site describes the compiler as producing `.n` bytecode executed by the VM, with a lightweight embeddable runtime and a C foreign-function interface. The Haxe manual records Neko as a VM originally designed for Haxe and says it was superseded by HashLink, introduced with Haxe 3.4. Nicolas Cannasse's 2016 HashLink article adds the historical detail that Neko was designed before Haxe and intended for several languages, but in practice NekoML and Haxe were the two that targeted it. ### 採用の歴史 Neko's adoption followed Haxe's early toolchain and server/runtime story rather than becoming a mainstream standalone language. The Neko GitHub repository's README marked the project deprecated on 2021-09-09, saying it is no longer actively maintained and is kept compatible with existing Haxe standard-library and language features. Despite that deprecation, package-manager usage persists because old Haxe projects, tooling, and runtime integrations still need it. Homebrew listed stable version 2.4.1 and showed 1,052 installs over 365 days, 174 over 90 days, and 72 over 30 days when checked on 2026-07-01. The GitHub API showed 584 stars and 110 forks the same day. ### 使われ方 Users install `neko`, `nekoc`, `nekoml`, and `nekotools` to run Neko bytecode, compile `.neko` sources, support legacy Haxe targets, or work with Neko's bundled libraries and Apache module history. Homebrew's formula notes the `NEKOPATH` environment variable, which matters because Neko expects to find its runtime libraries. For package nerds, Neko is less about new application development and more about keeping an older cross-language VM and Haxe target buildable. Its dependencies on a garbage collector, regex, TLS, database, and build tooling also show the VM's broader ambition as an embeddable and server-capable runtime. ### パッケージ好きにとっての重要性 Neko is significant as an early piece of the Haxe ecosystem and a predecessor to HashLink. It is a good example of a package that remains useful after deprecation because language ecosystems have long tails of bytecode targets, build scripts, and runtime assumptions. ### タイムライン - 2005: Haxe started; Neko predates or overlaps the earliest Haxe runtime design work. - 2013-05-25: HaxeFoundation/neko GitHub repository created. - 2016-11-22: HashLink article described HashLink as the successor to NekoVM for Haxe system/server/desktop applications. - 2021-09-09: Neko README marked the project deprecated and not actively maintained. - 2026-07-01: Homebrew formula stable version observed as 2.4.1. ### Related projects - Haxe - HashLink - NekoML - Motion-Twin - mod_neko ### ソース - - - - - - - ## セキュリティノート generalized runtime or code generation signal. -
