Another week, another release, runrunrun v0.3.0 is here. This release adds all the features I actually needed to start using this project myself on a daily basis.

What’s New

Fallback: The new -f/--fallback option (or RRR_FALLBACK=true) enables automatic fallback to previous matching rules when commands fail. This is useful when some commands aren’t found on the system:

https://* lynx
https://* chromium
https://* firefox

With fallback enabled, rrr -f https://example.com will try firefox first, then chromium, then lynx until one succeeds.

Alias redefinition: Redefining an alias now updates all rules using it, including previous ones:

[video] vlc
*.mkv [video]
*.mp4 [video]

# Now .mkv and .mp4 both use mplayer
[video] mplayer
*.avi [video]

Fix in desktop file support: Added support for more format specifiers (%f, %F, %u, %U) in desktop files (previously we only supported %U).

As always, feedback and contributions are welcome!

Just one week after the initial release, here comes runrunrun v0.2.0 with a key feature from the roadmap: desktop file import.

What’s New

Desktop File Import: The :import directive can now read .desktop files and automatically generate rules from their MIME types:

:import /usr/local/share/applications/gimp.desktop
:import /usr/share/applications

This extracts the Exec and MimeTypes attributes, infers file extensions, and creates the appropriate glob patterns automatically. It’s a great bridge for migrating from existing desktop configurations.

Path Expansion: Configuration files now support tilde (~) and environment variable expansion:

:include ~/.config/rrr/work.conf
:include ~/$DOTFILES/rrr/common.conf

Include Loop Protection: Fixed a bug where circular includes would cause infinite loops. Now if a file has already been included, it’s simply skipped.

Performance: The config parser now only loads rules for the requested profile, improving startup time for large configurations.

Getting Started with Import

If you want to import your existing desktop file associations:

# Import a specific application
:import /usr/share/applications/firefox.desktop

# Import everything
:import /usr/share/applications
:import ~/.local/share/applications

Desktop files without Exec or MimeTypes are silently skipped, so you can safely import entire directories.

Next Steps

With desktop file import now available, migrating from traditional file association systems is much easier. As always, feedback and contributions are welcome!
