Zotero LibreOffice Integration comprises extensions for LibreOffice and Zotero that communicate using local web servers.
LibreOffice SDK is not required.
To build:
scripts/symlink_sdk
.buildoxt.sh
from within the build
directory to build install/Zotero_LibreOffice_Integration.oxt
.Zotero_LibreOffice_Integration.oxt
into LibreOffice, either by choosing "Reinstall Extension" from within the Zotero preferences, by installing it manually from within LibreOffice, or by using unopkg
from the command line.
This extension is fairly straightforward. It consists of a LibreOffice UNO based java extension for LibreOffice. The UNO runtime allows various programming languages to interface with a running LibreOffice process. The extension code is initialized by LibreOffice and starts execution in ZoteroOpenOfficeIntegrationImpl.java.
Communication between Zotero and LibreOffice is mediated in zoteroLibreOfficeIntegration.js where a TCP socket is initialized and used for both sending and receiving messages. The complimentary socket connection on the LibreOffice extension end is found in CommServer.java.
The Java extension code can be debugged directly during runtime.
Follow these instructions to enable debugging in LibreOffice. After restarting, LibreOffice will freeze the until a debugging client connects. Create a remote debugging configuration in Eclipse and run it:
LibreOffice will unfreeze. If you add breakpoints in Eclipse they will be triggered freezing the LibreOffice process and allowing you to inspect the execution environment. This technique can be used to debug on remote or virtual machines too.
