xdg-sanity

The xdg-sanity script is built to replace your default web browser in your desktop/XDG settings. It intercepts http/s URIs sent to the default browser by xdg-open and sends it to the appropriate application. For example, it will send image/jpeg MIME type files to your image viewer.

Installation

Arch

I maintain a package on the AUR.

From Source

First, make sure you have curl(1) and handlr installed. Then, clone this repository and move the xdg-sanity/ folder into /etc and xdg-sanity.sh to xdg-sanity wherever your operating system stores locally-installed binaries. This is usually /usr/local/bin.

Then, create a xdg-sanity.desktop file either manually or with gendesk(1), placing it, also, where your OS stores locally-installed .desktop files, usually /usr/local/applications. Set your default web browser to be that .desktop file.

Now, add your default web browser to /etc/xdg-sanity/xdg-sanity.conf so the script can forward links to it.
