## 项目历史与用法

chruby is a minimal shell-based Ruby version switcher that changes the active Ruby by updating shell environment variables instead of using shims.

### 项目历史

The GitHub repository was created in August 2012 and early tags begin with v0.0.1 on the same date. The README highlights a deliberately small design: update PATH and RubyGems environment variables, support bash and zsh, default to system Ruby, and keep the implementation around 100 lines.

chruby's README frames its design through anti-features: it does not hook cd by default, does not install executable shims, does not regenerate shims after gem installation, and does not require Rubies to live in the user's home directory.

### 采用历史

The official README documents Homebrew installation, source installation, Arch AUR, Fedora Copr, FreeBSD ports, and pairing with ruby-install or ruby-build. The supplied package facts also show Homebrew, MacPorts, and Nix packaging.

### 使用方式

Users source chruby.sh from shell startup files and optionally source auto.sh to switch versions by reading .ruby-version files in the current or parent directories. Non-standard Ruby install directories can be appended to the RUBIES shell array.

### 为什么软件包爱好者会关心

chruby matters because it is the small-tool answer to heavier Ruby version managers. It plays well with package managers because it separates installing Ruby builds from selecting one in the shell, which keeps version switching inspectable and avoids shim directories.

### 时间线

- 2012: Repository created and v0.0.1 tag published.
- 2012: v0.1.x releases established the shell-based switcher.
- 2013: v0.3.x line matured around auto-switching and compatibility.
- 2023: v0.3.9 released.
- 2025: Repository metadata shows continued maintenance activity.
