Subject: Can't run preview latex after deleting prv files
Date: Thu, 06 Jun 2019 15:16:38 +0200

When running preview latex the first time on a document, everything is
fine.
But then when I delete the created folder _region_.prv and the files
_region_.log, prv_test.fmt, prv_test.log and _region_.tex, I can not run
preview latex (say with C-c C-p C-b)  anymore, it gives me the following
error

I want it to be as if I never ran preview latex, so that I can run it
again.
There must be some entry in some other file that gets created that I
have to remove.

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

I don't understand the intention behind it: If you start preview with
'C-c C-p C-b', you're fine, but why do delete the files above
unconditionally?  Remove them after your session, or use 'C-c C-p C-c
C-b' to delete them.

Best, Arash

Thank you for taking the time!

I am not 100% sure what exactly my specific intention was, but I am 
pretty sure that my point in the end was just that if I were to, 
intentionally or accidentally, delete those files, it seems to have 
"bricked" preview latex for that document.  As in, I was not able to 
ever make it work again.

Since I deleted all local (with respect to the latex document) files, 
and these weren't generated again, I assumed that maybe somewhere else 
it is recorded that there are supposed to be some files somewhere that 
now no longer exist, so I wondered where this was recorded.  Or I didn't 
understand the problem correctly.

I will try to recreate the behaviour, thank you for your time!

Thanks for your reponse.  I suggest we close this report for now.  We
can reopen this if the issue is still present and you have a recipe to
reproduce this.  Sorry it took so long.

Best, Arash
