 Yes, hello. As you know, Thor is the Nordic god of lightning, so lightning talks are stupid for me. I'm going to tell you about something I did about a year ago, but which, as far as I know, has actually been used. That's the comment from the commit. The idea is that if you want to compare saves of some document as ODF, you want to avoid differences that aren't relevant and don't see the actual semantical differences, if any, because you can use that for instance for regression testing to check that if in two versions of LibreOffice that shouldn't have any semantical differences in ODF output that there actually also are no differences, or check for what changes have been made to the actual contents of some document or something like that. Avoid irrelevant stuff, because normally when we say ODF, some parts with are pretty random, even if you have the same document and just save it using an identical way. To turn on this, you set this horribly named environment variable and as you see the one way is supposed to give you a hint that an ODF save display is not supposed to be used anymore to load into LibreOffice because I'm not quite sure if it actually is total legal ODF or it might have other problems. The two things that this environment variable turns on are it changes the automatic style names because those normally are, I don't remember exactly anymore, but if you check the commit comment it says what the problem is to them and the other one are some IDs in the ODF that are like typically totally random numbers because they need to be because they can be copy pasted into other documents and that's why they need to be more or less unique. So the patch just told the switch turns on that instead it uses just sequential int yards for them and if you want to get more instructions just look and give the log for the commit add. It has a fairly long description what it does and that's all. Questions? No questions so thank you.
