Junction lets you choose the application to open files and links.
Set Junction as the default application for a resource and let it do the rest. Junction will pop up and offer multiple options to handle it.
Set Junction as default browser
xdg-settings set default-web-browser re.sonny.Junction.desktop
Set Junction as default for all files
xdg-mime default re.sonny.Junction.desktop x-scheme-handler/file
Please note that this may not be respected by all applications but the command xdg-open will.
Set Junction as default for png
xdg-mime default re.sonny.Junction.desktop image/png
Set Junction as default email composer
xdg-settings set default-url-scheme-handler mailto re.sonny.Junction.desktop
Set Junction as default folder opener
xdg-settings default re.sonny.Junction.desktop inode/directory
Keyboard navigation
Use the menu or <Ctrl>? to learn about Keyboard usage.
Open with multiple applications
Use middle-click to keep Junction open - allowing you to open the resource in multiple applications.
Make Junction appear in the center of the screen
On GNOME you can make all new windows open in the center using
gsettings set org.gnome.mutter center-new-windows trueUse Junction from the terminal
Create a permant alias, for example alias open="flatpak run re.sonny.Junction".
Then you can use open my-file.
Add custom scripts to Junction
You can add your own script to Junction by creating a .desktop file for it in ~/.local/share/applications.
See https://wiki.archlinux.org/title/desktop_entries (distro agnostic).
Open links on a website with Junction
If you want links on your favorite websites to open Junction, set it as the default browser and use Tangram.
A browser extension might be coming.
Multiple Firefox profiles
See Profile Manager - Create, remove or switch Firefox profiles
If you want to be able to choose the Firefox profile to open the resource with, you can make desktop files for your Firefox profiles in ~/.local/share/applications.
Here is an example ~/.local/share/applications/firefox-work.desktop
[Desktop Entry]
Version=1.0
Name=Firefox work
Exec=firefox -P work --class=firefox-work %u
Icon=firefox
Terminal=false
Type=Application
StartupWMClass=firefox-work
MimeType=text/html;text/xml;application/xhtml+xml;application/vnd.mozilla.xul+xml;text/mml;x-scheme-handler/http;x-scheme-handler/https;
StartupNotify=trueSave, run update-desktop-database ~/.local/share/applications, enjoy.
I can't distinguish between options with the same icon
Within Junction, you can toggle Show names in the menu or hover the application with the mouse to display a tooltip.
Otherwise, you can edit the desktop files to use distinctive icons, here are a some tools
My app doesn't show up
If the application was installed via Flatpak, the package manager or an other conventional way, feel free to open an issue.
Make sure the application desktop file has a MimeType key that matches the type of resource you want it to handle. For example if you want the application ~/.local/share/applications/my-custom-browser.desktop to handle web content; add the following MimeType=text/html;text/xml;application/xhtml+xml;text/mml;x-scheme-handler/http;x-scheme-handler/https;.
The desktop filename should be unique. Junction can't display both /usr/share/applicatins/firefox.desktop and ~/.local/share/applications/firefox.desktop. The second overrides the first.
Finally - make sure to run update-desktop-database ~/.local/share/applications after installing a desktop file.
