Projektgeschichte

The project site frames ex-vi as source code for modern Unix systems. It traces vi back to Bill Joy's work at UCB starting around 1976, and notes that the old source became freely usable after Caldera removed usage restrictions from ancient Unix code under a BSD-style license in January 2002.

The port deliberately preserves traditional vi's small size, terminal control style, and feature set. Its changes focus on modern Unix portability, international character-set support including UTF-8, and selected later System V or POSIX.2 behavior.

Adoptionsgeschichte

ex-vi is adopted as a preservation-minded package rather than a modern editor platform. Package managers carry it for users who want traditional vi semantics, not Vim-style extensions.

The official page lists release 050325 as current and points adventurous users to a public CVS repository, while warning that CVS may be less tested than release archives.

Wie es verwendet wird

The vi manual describes vi, view, and vedit as visual-display editors based on ex. vi and ex share the same code, with users able to move between ex command mode and vi visual mode.

The manual documents ~/.exrc as a user configuration file, while the -s script mode explicitly disables EXINIT and .exrc processing.

Warum Paket-Nerds sich dafür interessieren

ex-vi matters to package collectors because it is close to historical Unix vi without the larger feature set of clones such as Vim or nvi. It is a compact compatibility and heritage package.

It is also a useful test case for ports that want a real traditional vi, UTF-8 support, and old ex behavior without bundling a much larger editor.
