Dirvana - Reach directory nirvana

Warning

Beta Status - We Need Your Feedback!

Dirvana is currently in beta. Found a bug? Have a feature request? Please open an issue!

Automatically load shell aliases, functions, and environment variables per directory.

Dirvana is a lightweight CLI tool that manages project-specific shell environments.

When you enter a directory, Dirvana automatically loads the configuration defined in .dirvana.yml, giving you instant access to project-specific commands and settings.

When you leave, everything is automatically unloaded.

The Problem

$ cd ~/projects/terraform
$ export TF_LOG=debug
$ alias tf="task terraform --"
$ alias plan="task terraform -- plan"
# ... and don't forget to unset everything when leaving!

The Solution

# .dirvana.yml
aliases:
  tf:
    command: task terraform --
    completion: terraform  # Auto-completion works!
  plan: task terraform -- plan

env:
  TF_LOG: debug

$ cd ~/projects/terraform
# Everything loads automatically!
$ tf <TAB>          # Auto-completion works!
  apply  console  destroy  init  plan  validate ...

$ cd ..
# Everything unloads automatically!
