My apologies - by "a long paper" I meant an academic paper which is long (ie 
many pages).
For publication in an academic journal, one needs to submit a Latex document 
using the journal's own document type, and the environments supported by that 
document type.
Many mathematicians write directly in Latex, but I much prefer to write in Lyx 
and export to Latex for submission.

It is very common for a paper to be redirected from one journal to another, and 
the submission document then needs to be changed to work with the new journal's 
document type.
In this use case, Jean-Marc Lasgouttes' solution (below) is very elegant and in 
fact shows another benefit of Lyx over raw Latex:

You could try, in Document Settings>Local Layout, something like

Style Paragraph
   ObsoletedBy SubsubSection
End

Style SubParagraph
   ObsoletedBy SpecialSection
End

Bulk changing environments in Lyx

[Dr Paul Verschueren]

Dear all -
I just had to change the AMS document type for a long paper.
I have made heavy use of the paragraph/subparagraph environments, but these do 
not exist(!) in the new doctype.
Is there any way of doing a find/replace via Lyx?
If not, is there any alternative to hacking the Lyx source, and does anyone 
foresee any gotchas with this approach?
(I'll obviously take a backup first).
Many thanks
Paul

RE: User list server settings

[Dr Paul Verschueren via lyx-users]

The Outlook client view has not changed. It does provide slightly more 
information (see attached screen shot).

I have not come across this form of address line on emails from any other 
source (it contains 3 email addresses!), so there is something unusual about it.



[cid:image001.png@01D7F286.F06688F0]



The “Reply” command believes the return address is:

“Daniel xraco...@gmx.de”

whereas “LyX Users lyx-users@lists.lyx.org” 
would be more useful here!

Re: I think we need a better name than "MWE"

[Dr Paul Verschueren via lyx-users]

It’s not perfect, but I think it is worth pointing out that this is not Lyx 
terminology, I have come across it in many communities. I note it has its own 
Wikipedia entry:

In computing, a minimal working example (abbreviated MWE) is a collection of 
source code and other data files which allow a bug or problem to be 
demonstrated and reproduced. The important feature of a minimal working example 
is that it is as small and as simple as possible, such that it is just 
sufficient to demonstrate the problem, but without any additional complexity or 
dependencies which will make resolution harder.

A minimal working example may also be referred to as minimal reproducible 
example or short self-contained correct example.

RE: Lyx on Chromebook - Yes it works!

[Dr Paul Verschueren]

I assumed that the relative silence indicated I'm on my own, so I thought I 
would make an initial investigation this lunchtime.
Great news - it turns out to be relatively trivial to get Lyx working under 
Chrome OS, and there is no need to compile a native app.

Chrome OS sets up a small VM with a copy of Debian 10, and Lyx 2.3.2 installs 
cleanly via apt(?) - even for a Windows die-hard like myself with no previous 
Linux exposure.
Performance does not seem an issue - there is a slight slow-down noticeable 
compiling a complex 40 page math paper, but it is perfectly acceptable (to me 
at least).
I now have several Word docs open, about 20 Chrome browser tabs, some pdfs, 
Debian and Lyx all running happily in 4Gb RAM and with a 32Gb disk - amazing!

The more challenging steps now will be replicating my custom Lyx environment 
under Linux (all those weird path names!), and gaining access to all my 
OneDrive disks (I've found a Linux utility called rclone, but it doesn't seem 
to like my multiple OneDrive setup). Again any previous experience/hints/tips 
would be most welcome.

My congratulations to all the team who have obviously kept the product lean and 
mean - I did not have high expectation of getting it working well on a 
Chromebook, but I was wrong!
Best wishes
Paul

Yes, garbage. there's no LyX app.

Qt does exist for Android, so it might be possible to compile LyX for Android. 
It would probably take some adjustments here and there. There's some info here:

Lyx on Chromebook

[Dr Paul Verschueren]

I'm just evaluating a friend's Chromebook - and I'm very impressed. It seems to 
do everything I want, at a fraction of the weight and cost of my old dying 
laptop ... with one exception - Lyx!
This link: https://www.bestchromebookapps.com/lyx-for-chromebook/  promises Lyx 
is available as an app. This is presumably just nonsense?

An offering called Rollapp promises to give me Lyx in the cloud which is fine 
in principle, but costs money.

Finally this link hints that it should be possible to get Lyx working via the 
Linux support under Chrome OS:
https://www.reddit.com/r/chromeos/comments/6lwrhz/lyx_on_samsung_plus_pro_over_crouton/

I might have a go at the last of these, but wanted to reach out first to find 
out if anyone has already tried this and has any tips (eg it doesn't work!) ?
The most obvious problem is space - the Chromebook has about 12Gb of available 
storage (less than the RAM on my old laptop!), so some careful disk management 
may be required.
Many thanks for any help/tips/comments.
Paul

Problem saving documents in Dropbox

[Dr Paul Verschueren]

Dear all -
Using LyX Version 2.3.2-1 (14 December 2018) under Win10, I am experiencing the 
problem described below with seemingly greater regularity.
I'm guessing the atomicity of the Lyx save/rename operation is being broken by 
a locking operation by Dropbox.
Does anyone know more?

The problem is intermittent and takes the form of a write failure on saving:
[cid:image001.png@01D4374F.61710D50]

When I press OK, I get:
[cid:image002.png@01D4374F.61710D50]

On pressing Retry, the document is saved.

Since it takes only a couple of clicks to complete the save operation, I have 
been living with this for a while, but it is getting irritating especially as 
the frequency appears to be increasing. Any suggestions (other than don't use 
Dropbox!) gratefully received.

Paul

This problem should be solved in LyX 2.3.3. There are still performance 
problems to look at[*], but this should fix the regression.

JMarc

[*] basically, I made a function faster, but it should also be called it less 
often. The two sides of optimization...

RE: Lyx sluggish on Windows 10

[Dr Paul Verschueren]

Yes I get the same problem with David's test file (i7 laptop, LyX Version 
2.3.2-1, up to date Win10).
I had noticed some sluggishness previously when the number of equations builds 
up, but not enough to make it worth raising as an issue.
However this test file is solid equations, and shows up the problem nicely - 
well done David!

Yes, pretty standard.

No, it should not. I doubt they are really usable as screen fonts, actually

Thank you for the document, I will try it out when I find the time (my main 
machine is linux).
Please keep it on your dropbox for now.

Does it make a difference if the rest of the document is text instead of math?
