## 项目历史与用法

OnDir is a small terminal automation utility for running directory-specific shell actions when a user enters, leaves, or passes through configured paths. Its core idea is deliberately narrow: pair shell startup hooks with entries in ~/.ondirrc so path traversal can change process-local state such as umask values, environment setup, or virtualenv activation.

### 项目历史

The upstream documentation presents OnDir as a compact C and shell tool by Alec Thomas, with source tarballs from 0.1.0 through 0.2.2 published on the project page and a mirrored GitHub repository containing the README, man page, shell hooks, and configuration examples. The project stayed small by design; the README describes the behavior as simple but effective.

### 使用方式

Users install shell hooks for Bash, tcsh, zsh, or fish and then define enter and leave sections in ~/.ondirrc. The examples cover a public_html umask change, multiple paths per section, tilde and environment-variable expansion, regular-expression path matching, and automatic activation or deactivation of Python virtual environments.

### 为什么软件包爱好者会关心

OnDir is an early Unix-style answer to per-directory environment automation: tiny, text-configured, and shell-integrated rather than a large daemon. For package nerds, it is interesting less for scale than for how long the directory-hook pattern has been packaged as a standalone CLI.

### Related projects

- The project sits in the same conceptual space as shell prompt hooks and per-directory environment tools, but its implementation is limited to running configured scripts during directory traversal.
