[SOLVED] Open file based on extension and not just file/mime type

[VanessaDeagan]

I use Unreal Engine 4, it produces C++ project files for CodeLite (e.g. MyProject.workspace). The type of this file is application/xml.

I can right-click on MyProject.workspace and then select Open With, Other, Development, CodeLite, which works fine, but it's annoying having to do that each and every time. It also means that when UE4 creates MyProject.workspace, it opens it with Firefox instead of CodeLite (I then have to close Firefox, navigate to the directory, then do the "Open With" thing).

If I right-click on MyProject.workspace, then select Properties, General Tab, File Type Options, and then add "*.workspace" to the "Filename Patterns" section, and "CodeLite" to the "Application Preference Order" section, then all XML files are opened with CodeLite (which is not what I want - I only want CodeLite projects (*.workspace) to be opened with CodeLite).

How do I configure KDE to open files of type application/xml, but with the extension *.workspace, with CodeLite?

Managed to solve this:

1. Go to System Settings.
2. Click on Applications.
3. Click on File Associations.
4. Expand Application in the Known Types tree.
5. Click the Add button (make sure "Group" is set to "Application").
6. In the Name textbox, enter: x-codelite-workspace (and click OK).
7. In File Patterns, click the Add button and add *.workspace
8. In the Application Preference Order click the Add button add CodeLite.
9. Optional: click on the icon box and select the CodeLite icon (which is in System Icons | Applications).
10. Reboot (changes didn't take effect until I rebooted - there's probably a way of doing this without a reboot).

Nice work! Thanks for posting your solution.
Concerning step #10 - just logging off and back on will also work.

An aside: One can use kcmshell5 in a Konsole to see and do many things on the CLI
