The freedesktop Menu Specification provide 2 kinds of registered categories, the main ones and the additional ones. If I put the following into an ebuild: make_desktop_entry zita-dc1 zita-DC1 zita-dc1 AudioVideo:Audio:Engineering the spec tell me than Engineering can be used with any main category, and than Audio must include AudioVideo as well. which imply 'AudioVideo:Audio:Engineering' is correct. But emerge and ebuild tells me: * QA Notice: This package installs one or more .desktop files that do not * pass validation. * * /usr/share/applications/zita-dc1.desktop: error: value "AudioVideo:Audio:Engineering;" for key "Categories" in group "Desktop Entry" contains an unregistered value "AudioVideo:Audio:Engineering"; values extending the format should start with "X-" The final statement of that notice is wrong because AudioVideo, Audio and Engineering are all registered menu categories. Which imply X- doesn't apply in such a case. Reproducible: Always Steps to Reproduce: 1. make_destop_entry with additional categories 2. install the software with ebuild or merge it with emerge Actual Results: portage make the desktop entry as wanted, which is fine. But the QA notice is misleading and wrong.
And I made a mistake. With the above desktop entry command, the QA notice is correct because I used ':' instead of ';' semicolums. But it is even worst with the use of make_desktop_entry zita-dc1 'zita-Dynamic Compressor 1' zita-dc1 AudioVideo;Audio;Engineering The result is * QA Notice: command not found: * * /var/tmp/portage/media-sound/zita-dc1-0.3.3/temp/environment: line 1621: Audio: command not found * /var/tmp/portage/media-sound/zita-dc1-0.3.3/temp/environment: line 1622: Engineering: command not found So, I try to put the cats in quotes and everythins is working fine: make_desktop_entry zita-dc1 'zita-Dynamic Compressor 1' zita-dc1 'AudioVideo;Audio;Engineering;' One solution can be to close that bug as invalid. Another solution would be to change it into a documentation improvement for https://devmanual.gentoo.org/eclass-reference/desktop.eclass/index.html and add an example like that one.
AudioVideo;Audio;Engineering these are separate commands, after ; it tries to execute Audio, then Engineering, not pass it to make_desktop_entry You need to use quotes For an example from app-emulation/ruffle: > make_desktop_entry ${PN} ${PN^} ${PN} "AudioVideo;Player;Emulator;" \ > "MimeType=application/x-shockwave-flash;application/vnd.adobe.flash.movie;" (can leave out the mimetype part, just an example of what you can do)
