## プロジェクトの歴史と使われ方

ircII is a source-distributed Unix IRC and ICB client maintained by the ircII project. It is important in package history because it represents the early terminal IRC client tradition from which several later Unix IRC clients took inspiration or code.

### プロジェクトの歴史

The project site describes ircII as an IRC and ICB client for most Unix platforms, distributed in source form and maintained by a group that incorporates fixes and features. Its release news shows date-stamped source releases continuing through the 2000s and 2010s, including changes for SSL IRC servers, UTF-8 handling, lastlog behavior, macOS fixes, sanitizer-derived bug fixes, and generated HTML help.

The package's long-lived source archive style is part of its identity: the project publishes tarballs and a daily expanded source tree rather than presenting a modern forge as the primary source-control interface.

### 採用の歴史

ircII appears in Homebrew, Debian, Ubuntu, MacPorts, Alpine, and other package indexes because it remains a compact terminal client for IRC users who prefer a classic Unix interface. IRC help material also documents ircII as a Unix-shell client and discusses EPIC and other clients in relation to ircII.

### 使われ方

Users run `irc` or versioned helper binaries from a terminal to connect to IRC or ICB services. The Debian manpage describes it as a full-screen termcap interface that exposes normal IRC functions plus additional options, which matches its package-manager role as a lightweight console chat client.

### パッケージ好きにとっての重要性

ircII is package-nerd material because it preserves an older Unix distribution model: source tarballs, termcap UI, generated help files, and small command-line companion programs. Its versioned executable names in package managers are a reminder that old IRC clients often need to coexist with scripts and user habits built over decades.

### タイムライン

- 2006: Project news lists public releases in July 2006.
- 2011: Project news lists the 20110228 and 20111115 releases.
- 2014: Releases added HTTP proxy and SSL IRC server support, followed by resize and display fixes.
- 2017: A release focused on UTF-8, log, lastlog, resize, and macOS fixes.
- 2019: Releases added lastlog restore support and early HTML help conversion.
- 2021: A release included memory leak, crash, and sanitizer-derived fixes.
- 2024: The project published 20240111 and 20240918 source releases.
- 2026: The project published the 20260115 source release.

### Related projects

- ircII is historically adjacent to other Unix IRC clients such as EPIC, BitchX, ScrollZ, Irssi, and WeeChat, and to ICB clients through its combined IRC/ICB support.
