## プロジェクトの歴史と使われ方

OpenVi is a portable packaging of the OpenBSD vi/ex editor for Unix-like systems outside OpenBSD. Its significance is preservation and portability rather than a new editor model: it gives package users a small BSD-licensed vi derived from OpenBSD base-system code.

### プロジェクトの歴史

The OpenVi README describes the project as a fork of the vi/ex editor included with OpenBSD. That editor descends from nvi 1.79, the Berkeley ex/vi reimplementation associated with Keith Bostic, Sven Verdoolaege, and other CSRG contributors, and nvi itself traces back through Steve Kirkendall's Elvis editor.

OpenVi follows the common OpenBSD-portable pattern: take audited base-system code, add portability glue, and make it build on other Unix systems. Its README emphasizes readable code, secure C library idioms such as strlcpy, snprintf, mkstemp, and pledge where available, and a permissive BSD/ISC licensing mix.

### 採用の歴史

OpenVi's adoption footprint is niche. It is packaged by Homebrew, Alpine, and Nix for users who want OpenBSD's vi behavior without installing OpenBSD, but it does not appear to be a general editor ecosystem on the scale of Vim, Neovim, or nvi2.

Its most natural audience is package minimalists, BSD users working on non-BSD hosts, and developers who want a small vi with OpenBSD ancestry rather than plugin systems, scripting runtimes, or GUI layers.

### 使われ方

The package installs ovi, oex, and oview so users can edit files, run ex commands, and inspect files with a vi-family tool. It is useful in lightweight shell environments, recovery setups, containers, and systems where a traditional vi is wanted with few moving parts.

### パッケージ好きにとっての重要性

OpenVi is interesting because it packages a lineage rather than a feature race: Berkeley vi to nvi to OpenBSD vi to a portable downstream. For package nerds, that makes it a compact case study in base-system code being exported into package-manager space.

### タイムライン

- 1996: nvi 1.79 becomes the ancestor named by the OpenVi README for OpenBSD vi.
- 2020s: OpenVi is distributed as a portable OpenBSD vi for Unix-like systems and appears in package managers including Homebrew, Alpine, and Nix.
- 2026: Homebrew packages OpenVi 7.7.32 with ovi, oex, and oview.

### Related projects

- OpenVi is related to OpenBSD vi, nvi, nvi2, Elvis, Vim, Neovim, and other small Unix editor ports that preserve traditional ex/vi behavior.
