プロジェクトの歴史

The suckless source log reaches back to early 2007, with release tags appearing that year. The project page and README define ii's core idea plainly: make IRC scriptable with standard command-line and filesystem tools instead of a large terminal client UI.

Over time ii kept the same small-file abstraction while accumulating pragmatic Unix fixes: portability changes, manual-page updates, OpenBSD pledge support, release bumps, and later direct TLS support through libretls.

採用の歴史

ii's adoption has been strongest among Unix minimalists, suckless users, and people writing bots or personal IRC workflows. Its package-manager spread across Homebrew and Linux distributions reflects that it is small enough to package but distinctive enough to keep around.

使われ方

A user starts ii against a server, then writes IRC commands to `in` files and reads messages from `out` files. Joining a channel can be as simple as echoing `/j directory.

パッケージ好きにとっての重要性

ii is a canonical tiny Unix package: the interface is the filesystem, composition happens with shell tools, and the implementation goal is small enough to audit. It is useful package-manager lore because it shows how far plain files and FIFOs can replace application UI.

タイムライン

• 2007: Early public source history and 1.2/1.3 release tags.

• 2011: Version 1.6 kept the implementation under a small line-count target after restructuring.
• 2016: OpenBSD pledge support added.
• 2022: Version 2.0 release bump.
• 2025: Direct TLS support added.

Related projects

• ii is part of the suckless tools family and is described by suckless as the big brother of sic. It is also conceptually related to filesystem- and FIFO-oriented chat clients and shell-driven IRC bot workflows.
