プロジェクトの歴史

The reproduced man page and source identify Ben Crowell as the author and give a copyright range beginning in 2003. The page's included man page is for When 1.1.46 dated 21 December 2011, while the Bitbucket repository now carries the source history and tags.

Bitbucket repository metadata shows the current public repository was created in January 2023, but tags exposed through the Bitbucket API include version 1.1.30 in January 2013 and later 1.1.39 through 1.1.45 releases from 2020 to 2022. The project therefore predates its current hosting location.

採用の歴史

When's official page documents packaging across traditional Unix-like systems, including Debian and Ubuntu, Gentoo, FreeBSD, and Slackware-family packaging. That adoption pattern fits the tool's design: a small Perl script with no library dependencies is easy for distributions and ports trees to carry.

使われ方

The basic workflow is to run when, let it create initial setup information, edit the plain-text calendar with when e, and then run when to print upcoming items. The default report covers the next two weeks, while commands can show weekly, monthly, or yearly ranges, wall-calendar grids, the current date, or modified Julian days.

Calendar entries are simple text lines such as a date followed by a comma and description. The program also supports recurring date expressions, language handling, UTF-8 input, pager and terminal styling options, and a prefilter mechanism for splitting larger calendars through tools such as m4.

パッケージ好きにとっての重要性

When is package-nerd significant as a small, inspectable Unix productivity tool: it stores user data in text, delegates editing to the user's editor, and avoids library dependencies. It is the kind of program that survives in package archives because it is easy to understand, easy to patch, and compatible with old-school shell workflows.
