HI JMarc,
 That was the query I had before. Together, the three
files amount to
nearly 1400 kilobytes.  Is that too large to send to the list?


I would propose to attach a compressed version to ticket

Bonjour Jean-Marc,

   I am in the middle of another update using Compare,
and have found a couple of small errors, when the Differences
file  is showing the change incorrectly.  The files are nearly 500 kB
and thus might not be welcome on the Users list.

I can extract the errors and post them as plain text,  send the
complete files as an attachment,  or send the files directly to you.


Dear Gordon, please keep discussions on the list, it is easier for 
others to follow.


You can directly send a pair of file to me, but the best of course would 
be to build small documents that exhibit problems, if you can do that.


I suspect that your problem is http://www.lyx.org/trac/ticket/6889

I turns out that the original author of Compare is busy right now, and 
that nobody else knows the code. Yet, if a determined user could 
describe when the problem occurs and when it does not, we might be able 
to do something in some common cases.

  Am using Compare right now and have not had a repeat of the
reported problem.

  Found a small error,  here are the related extracts.  Note that the
 numbered lines were correctly classed as Enumerate in both texts.

1. /Original lines/:


   "3.6.3 Troubleshooting

 * No sound, though speaker icon is in the Notification Area.
 o Try raising all controls to a higher level.
 o Edit the configuration file directly: see Section 7.4.
 * No sound, and no speaker icon is in the Notification Area. It could
   be that the sound card is missing or unrecognized, but the most
   common problem is that of multiple soundcards, which we address here.
1. Solution 1: click *Start menu > Settings > MX Sound Card*, and
   follow the screen to select and test the card you want to use.

3. Solution 3: enter the BIOS and turn off HDMI"

Just about to work on more comparisons, will report on any errors later.

I recall reading some time ago that if we switched the LyX source to
valid XML, our diff troubles would evaporate (along with a number of
other difficulties, like epub conversion). Is this still so? And are
we any closer to XML'ing .lyx files?

I'm not sure, but indeed one can expect that a xmldiff tool exists 
somewhere and one may hope that it is correctly implemented :)

No, we did not move on that. I tend to be suspicious of miraculous 
solutions, though.

A quick search for "xmldiff" suggests that we'd be more hard-pressed
to choose one, rather than find one:

Re: best practices for Compare feature?

[Gordon Cooper]

Hello Liviu,

 My use of Compare is fairly frequent.  Document is the User
Manual for an operating system which may be changed/updated
several times a year, then released in html and pdf.

Manual is written in Lyx. My task is producing the pdf and because
of aspect ratio differences between images in html on a screen
and in pdf for possible printing, we have a separate Lyx master
for pdf conversion.  Compare is used to update this master.

Compare is excellent for finding changes, including  minor
punctuation and in hyperlinks. Twice I have had the same
problem as Bert where the synchronisation between documents
is lost and Compare thinks that every character has changed.

Regards,
Gordon.

What was the interest for this particular Compare? Did you want to
see/edit changes within LyX, or simply to visualize differences
between files. If it is the latter, then one approach that could help
would be to use an intermediary file.

Re: best practices for Compare feature?

[Bert Lloyd]

Dear all,

Thanks for your comments. Just to follow up, as in Gordon's
experience, when the Compare process did conclude, the result was as
if every character had changed.

Unfortunately I can't share the document publicly.

Best,
BL

Certainly, will do.  Files are a software manual and readily

best practices for Compare feature?

[Bert Lloyd]

Dear LyX users,

I am attempting to compare two versions of a LyX document using Tools
- Compare. The document is roughly 60,000 characters including spaces,
and my rough estimate is that 5% of the document has been changed
between the two versions.

I suspect I am doing something wrong, because the tool has been
running for over an hour, reports 40,000+ differences, and that it is
0% complete.

Any advice?

Thanks,

BL

I think it is just a difficult feature of LyX to implement correctly.
You can see the current bugs that we are aware of for the comparison
feature here:

http://www.lyx.org/trac/query?status=accepted=assigned=new=reopened=~=compare=~=~=id=summary=reporter=status=type=severity=keywords=1=id

If you don't have one of those issues and you can provide a reproducible
example, please make a bug report.

Re: best practices for Compare feature?

[Gordon Cooper]

 Dear Bert,
   I have had this problem, without finding the cause. 
I use

Compare quite often on a 100 page document (which has multiple
maintainers and regular updates), and usually, the Differences
file is generated in a few minutes.

Twice, Compare has behaved as you describe and when I stopped the
process  then restarted it the problem had gone.  I came to the
conclusion that synchronisation had been lost between the two copies,
and that every character was then considered as having changed.

Perhaps that idea is incorrect, but Compare is working properly more
than 90% of the time.

Regards,
Gordon.
