How do I add custom items to the context menu in Dolphin in KDE 5?

I've Googled around, but can't seem to find any consistent tutorials or documentation that describe how to do this (in my case, on Kubuntu 15.10). I want to add custom scripts to the context menu in Dolphin (a la nautilus-scripts for Nautilus). For some reason, when I follow any instructions I find, I'm only able to make the context menu appear when right-clicking the relevant .desktop file. How can I solve this?

Solution 1:

KDE Service Menus

In KDE-speak a "servicemenu" is a special entry that appears in a context menu (or other context-based interface) for a file (or for directory), depending on the type of files that are selected.

Paths

KDE Frameworks 5 is looking services from:

kf5-config --path services

Executing:

$ kf5-config --path services
/home/user26687/.local/share/kservices5/:/usr/share/kservices5/

That is:

User servicemenus are:

$HOME/.local/share/kservices5/ServiceMenus/

System servicemenus are at

/usr/share/kservices5/ServiceMenus/

Desktop files

Servicemenus are defined using .desktop files. Desktop Entry Specification: https://standards.freedesktop.org/desktop-entry-spec/latest/

An example - simple servicemenu with file path:

Making: $HOME/.local/share/kservices5/ServiceMenus/myFirstServiceMenu.desktop

If the directory doesn't exist the user can make it !

[Desktop Entry]
Type=Service
Icon=smiley-shape
X-KDE-ServiceTypes=KonqPopupMenu/Plugin
MimeType=all/allfiles;
Actions=helloWorld;
Encoding=UTF-8

[Desktop Action helloWorld]
Name=Hello with path information
Icon=smiley-shape
Exec=kdialog --msgbox "Path is %f"

Closing all Dolphin windows and starting a new one. When right clicking a file:

Solution 2:

The following worked for me on Ubuntu 16.04

place the scripts in the directory ~/.local/share/kservices5/ServiceMenus/

run kbuildsycoca5

scripts will be visible in new dolphin instances.
