プロジェクトの歴史

The official Chordii site traces the project to the original CHORD program by Martin Leclerc and Mario Dorion. It says the chord notation was invented in June 1991, with original releases recovered from 1992 archives and the last known original CHORD 3.6.2 distribution dated July 1995.

Johan Vromans and Adam Monsen revived the unmaintained program in 2007 after being unable to contact the original authors. The revived project was first called Chordie, then renamed Chordii in 2008 to avoid confusion with chordie.com.

A major packaging milestone came in December 2009, when the original authors agreed to a GPL-only CHORD 3.6.4 release. Chordii 4.3 was then rebased on that release, making it officially GPL and suitable for inclusion in distributions.

採用の歴史

The official news page records Fedora approval for Chordii 4.3 in January 2010, with inclusion planned for Fedora 13 and updates for Fedora 11 and 12. The supplied package-manager facts list Homebrew, Debian, Ubuntu, and MacPorts packages.

Homebrew currently packages Chordii as a niche formula with stable version 4.5.3b and low install counts, consistent with a specialized music-notation utility rather than a broad CLI platform.

使われ方

Chordii reads lyrics and chord annotations in ChordPro format and emits PostScript song sheets with titles, chord names above words, chord diagrams, columns, indexes, multiple logical pages, configurable fonts, and songbook support.

The 2013 Chordii 4.5 news item added reading input from standard input, explicitly making Chordii usable as a filter in toolchains.

パッケージ好きにとっての重要性

Chordii matters to package-history people because it preserves an early plain-text music notation ecosystem: a 1991-era Unix tool, alt.sources-era releases, licensing cleanup for distro inclusion, and a later handoff to the ChordPro project.

Its long tail in Homebrew, Debian/Ubuntu, MacPorts, and Fedora history shows how small domain-specific command-line tools survive through package managers long after their main upstream development has slowed or moved to a successor.
