LyX 2.3.4 and Evince/Okular synctex

[Ben Houcine]

After a week of Linux distros tests I settled yesterday with 
manjaro-gnome-19.0.2. This distro worked fine with the latest version of 
LyX.Concerning LyX synctex with Okular I have the following note to add to the 
pageLyX wiki | LyX / SyncTeX
The following are necessary:
1) In Document > Settings > Formats, check Synchronize with output (In windows 
10 it's not necessary to do that because I think there is a difference between 
TeXLive versions in Windows and Linux and how they work)
2) Tools → Preferences → File Handling → File Formats
Select the format PDF (pdflatex)Set the Viewer field to Custom with a command: 
okular --unique
as seen this screenshot
https://imgur.com/Wf3aw9U



I note also that so far I have tested the command "okular --unique" don't work 
properly in Windows ports of okular.

- Synctex with Evince:It works great in my manjaro-gnome-19.0.2 tests, the only 
issue is that using the scripts 
http://www.spitzmueller.org/tools/lyx/evince_sync_lyx.zip
evince don't start maximized even if you save window settings in it.My solution 
is to edit the preceding scripts and replace "evince" by the command "evince 
--fullscreen"

- LyX version 2.3.4.4 (testing version):So far in my tests, I din't see any 
issue in Windows 10.

Okay, found the problem. For some reason, the encoding of my master 
document (Document > Settings > Language) was set to (non-default) utf8 
but the others were (default) latin9. Not sure why it didn't get me into 
trouble before. But now it works again.

Re: Preview a single child document while maintaining counters and references

Right. That’s even better. Thanks.

 You mean, without the master? No. I don't think that's possible in
 LaTeX either.

And with LyX

No. There is GUI support for it. Go to Document > Settings > Child
Documents (in your master file), select "Include only selected
children", select the chapters you want to include, and click "Maintain
counters and references" to have the complete document compiled once
before only the \includeonly documents are completed.

A drawback currently is that "Maintain counters and references" makes
LyX execute the extra compilation every time, which increases
compilation time.  Normally, you can uncheck it if the document has
been built once and if you only change the included document.

Ideally LyX should be smart enough to detect changes and do the
complete execution only if necessary.
