[Solved] Detect if LibreOffice Extension is installed and activated

[dhoelzl]

Hello!

We are developing an extension with VB macros for LibreOffice.
Our macros are then called via

Code: Select all

soffice.com --nodefault --norestore "macro:///<OurLibrary>.<OurModule>.<OurMacroFunction>(<Arguments>)"

This works perfectly fine if the user has installed our extension. However if the extension is not installed, just nothing happens. No output to stdout/sterr, and the exit code is still zero, like on the successfull call.

Is there any (clean) possibility to check if the user has installed the extension from external?
Is there a possibility to return a value from the macro?

Probably one workaround would be to add a macro function which writes something into a file passed by an argument, and then check if the data was written or not, but that's a workaround that I would like to avoid.

Thank you and regards,
Dominik

C:\Program Files\OpenOffice4\program\unopkg list apso.python.script.organizer
returns all info about installed apso.python.script.organizer

Thank you, that resolves my problem.
In my case I have to call "C:\Program Files\LibreOffice\program\unopkg.bin" list org.openoffice.legacy.<ExtensionName>.zip and check the output for "is registered: yes", the exit code is zero if it exists and 1 if not.
