プロジェクトの歴史

The official GitHub repository was created in July 2018, and the first listed GitHub release, v0.1.0, was published on 2018-10-12. It is written in Rust and integrates with Bash, Zsh, Fish, and PowerShell rather than replacing the shell itself.

McFly's README emphasizes reversibility: it augments shell history in a SQLite database while maintaining the normal shell history file, so users can stop using McFly without losing the conventional history path. That design choice helped it fit into conservative shell setups.

採用の歴史

The supplied package-manager facts list McFly across Homebrew, MacPorts, Alpine, Arch, Nix, Scoop, WinGet, and openSUSE/Zypper, showing broad packaging across Unix-like and Windows-adjacent ecosystems.

The README documents Homebrew, MacPorts, WinGet, install-script, manual release, source, and Zinit installation paths. It also includes release-process notes for Homebrew, reflecting long-running package-manager maintenance rather than a one-off binary upload.

使われ方

Typical use is rebinding Ctrl-R in a shell startup file so McFly opens a full-screen history search UI. The tool stores enhanced history metadata in an OS-specific SQLite database and can dump history to stdout for scripting or inspection.

McFly's settings are mostly environment-variable based, with color settings stored in a config.toml under the McFly data directory. The README documents the macOS application-support path, Linux XDG data path, and a legacy ~/.mcfly fallback.

パッケージ好きにとっての重要性

McFly is package-nerd interesting because it modernized an old shell muscle-memory path without requiring a new shell or large framework. It is a Rust CLI with many package-manager entries, a small executable surface, and visible cross-shell integration details.

Its use of SQLite for enriched history also makes it part of the broader trend of CLIs turning plain-text shell workflows into indexed local databases while preserving escape hatches back to ordinary files.

• Related shell-history tools include fzf-based Ctrl-R bindings, atuin, hstr, and shell-native history search. McFly's official positioning is specifically an intelligent replacement for Ctrl-R rather than a full shell environment.
