history

Project history and usage

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.

Project history

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.

How it is used

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.

Why package nerds care

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.

Recommended review

Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.
