## プロジェクトの歴史と使われ方

frum is a Ruby version manager written in Rust. Its README positions it as a fast, modern alternative in the Ruby toolchain space, with support for `.ruby-version` files, shell initialization, completions, and Ruby installation commands.

### プロジェクトの歴史

The project appeared publicly as a 0.1.0 alpha series in April 2021 and reached v0.1.0 in May 2021. Its README emphasizes a pure Rust implementation that does not use ruby-build, cross-platform support for macOS and Linux, and faster shell initialization than rbenv in the included benchmark.

The release history stayed small, with v0.1.2 published in November 2021. The README references fnm, a Rust-based Node.js version manager, which places frum in the family of small compiled version managers built for quick shell startup.

### 採用の歴史

frum's official installation section documents Homebrew/Linuxbrew, Arch AUR packages, Cargo installation, and release binaries. The v0.1.1 release notes explicitly mention Linuxbrew installation, showing package-manager support as part of its early adoption path.

### 使われ方

Users initialize frum in their shell profile with `frum init`, then install, uninstall, list, and select Ruby versions with subcommands such as `install`, `versions`, `global`, and `local`. The tool also supports `.ruby-version` files so it can fit into existing Ruby project conventions.

The README documents `$HOME/.frum` as the default installation root, with `--frum-dir` and `FRUM_DIR` available when users need a customized location.

### パッケージ好きにとっての重要性

frum is notable as an example of the Rust rewrite wave reaching language-version managers: it borrows the fast-startup pitch common to tools like fnm while targeting Ruby workflows historically served by rbenv, chruby, RVM, and ruby-build-based tooling.

### タイムライン

- 2021: v0.1.0-alpha.0 was published as the first GitHub release.
- 2021: v0.1.0 followed in May with global config options.
- 2021: v0.1.1 added documented Linuxbrew installation support.
- 2021: v0.1.2 fixed Homebrew OpenSSL usage.

### Related projects

- The README lists Schniz/fnm as a reference project.
- The benchmark compares shell initialization against rbenv, making rbenv an important adjacent Ruby version manager.
