change tracking for mathed

[Xu Wang]

I'm just curious as to whether change tracking will be implemented for
mathed or if there is some fundamental problem with doing so. I imagine it
will take a lot of work, but just curious if it's on anyone's (long term?)
todo list.

Re: can't clone git (non-developer)

[Xu Wang]

"git branch" lists only one branch for me (master). Should there be more?

can't clone git (non-developer)

[Xu Wang]

I am not developer but would like to clone the git.
I am following the new guide here http://wiki.lyx.org/Devel/LyXGit

git clone git://git.lyx.org/
Cloning into git.lyx.org...
fatal: The remote end hung up unexpectedly

Even though not a developer I should still be able to clone right?

Re: git.lyx.org - developers! your ssh public key please

[Xu Wang]

Excellent! How does this work for non-developers? For example, I would like
to be able to do something and then do a pull-request. I think at this
point I can only fix typos and maybe a small error, but my work would need
to be verified.

Thank you for this, Xu

Sorry to already break the silence. Am I right that if we were using git
now, there would be no problem with the server going down or whatever
maintenance is going on right now? Because everyone could still work on
their own branches and then everything could be merged easily.

Or is this also easy to do in SVN? I'm curious.

Thank you Richard! On my setup I gthink it's lib/bind/

Re: Import into LyX

[Xu Wang]

Hey Rob, that sounds like quite a nice project you have in mind!

My two cents: it's not worth carrying it out if you can't get the math to
import somewhat well. That seems to be the biggest problem with most ways
of converting doc to lyx. I understand it's very difficult, but I think
it's also the most important.

I don't mean to discourage you, just my two cents. I don't think importing
track changes is important at all (they should be able to go through the
changes in word and get rid of them). And I don't think round-tripping is
important. Of course, if you could pull these features off they would be
nice additions.

I looked at the google code project and it looks like it's still under
development. Is that correct? It would be nice to choose a library that is
still being actively developed.

Good luck with it all and thanks for your effort on this. I think in the
end it would indeed help a lot of would-be LyXers or already-LyXers but
need to collaborate with a Word-er.

Re: plans for Sweave

[Xu Wang]

Yihui,

Thank you for your contributions! It's especially impressive how you're
continuing to develop LyX support and documentation of Sweave, even though
in some sense knitr is a competitor. From what I have been reading, knitr
has clear advantages.

Are the following correct?

1. knitr will be integrated in LyX 2.0.3 (through a module) without
additional customization.
2. there will be knitr and sweave manuals in the help>specific manuals in
LyX 2.0.3.

Thanks so very much, Xu

Hey Nick,

Your last edit seems to have been made a month ago. Are you done or just
taking a break? You were very straightforward that you would only work on
it until you got bored, so I'm not at all asking anything of you. I'm just
curious :).

Thanks a lot for what you have done!

using git

[Xu Wang]

>From what I've read, svn will be replaced with git for LyX development. And
I guess some developers are using git already? I have been reading
http://wiki.lyx.org/Devel/Git

Will git eventually fully replace svn or will we always rely on git-svn? If
fully replace, is there any (rough) estimate on when this will happen (e.g.
1 year)?

Thanks,

Xu

Nick,

Thank you for the explanation! Your outside interests are definitely
understandable. Whatever you can accomplish will be greatly appreciated. I
actually prefer a .lyx file to a wiki file.

I wonder if this could be a new manual, "Developing LyX". It could be
hidden from the average user, just as the information inset is hidden and
can only be activated with a keyboard shortcut. Or it could be visible.

Re: idea for LyX 2.1.0: allow to paste text lists directly to tables

[Xu Wang]

+1

This would really be great and I've met several people that expected this
from the "paste special" menu option and were then disappointed.

Is it possible to use already existing code, e.g. from libre office, that
has such functionality?

I'm guessing there are some technical issues that make this feature
difficult to implement.

Great, thanks for all of the advice! I just noticed a .ui folder in the

Qt creator?

[Xu Wang]

I'm learning Qt from  "C++ GUI Programming with Qt 4" and am curious if
most LyX developers write Qt C++ code using a text editor or Qt Creator? I
would like to get used to doing whatever others are doing to make
communication and questions easier.

Thanks,

Xu

Re: #7894: Cannot use keyboard to "find next"

[Xu Wang]

Hi Maynard,

Thanks for your reply! I'm not sure what the protocol is for responding in
private or to the list. I was just curious. You are welcome to respond to
my messages on the list. In fact, this time I was surprised you didn't!

Thank you for clearing that up. I can definitely relate. I've had many
jokes go over not so well in email and text messages. I've learned that
sarcasm especially is something to avoid in textual communication.
Rereading your comments trying to see the humor or sarcasm though, I still
couldn't. It still seems offensive and rude to me. Either that's my
inability to see it, your inability to convey it, or just lost meaning
through text.

Thank you very much for taking the time to clear up a misunderstanding.
Many people get into disagreements and just "shut the door". Communication
is always good.

I'm replying to the list since I assume you want others to see your
explanation and I think you might have intended to send it to the list
anyway.

Best,

Xu

Re: #7894: Cannot use keyboard to "find next"

[Xu Wang]

Dear Maynard,

I think Richard's reply was actually quite polite compared to yours. I'm
not sure what it is that you don't understand. English seems like your
native language (you probably speak it better than me lol), so I'm guessing
that you do understand the meaning of the words you chose to use. Just in
case though, here are some examples:

You start off by "This is ridiculous". From what I understand, you are
suggesting that it is ridiculous that the LyX developers have not fixed
this bug. That is quite offensive. It is insensitive and suggests that they
are not correctly doing their job. It kind of sounds like you're saying
that *they* are ridiculous.

'DON'T do the half-assed job... do the job properly.'
--Assuming that English is your native language, you should realize that
these statements are commands. These are demands. Further, using capital
letters is analogous to shouting in spoken English.

As a final note, I just want to say that I can relate to you, Maynard. I
have often been quite frustrated with bugs that stay around for a long
time. I haven't had this happen in LyX, but in many other projects, both
open sourced and proprietary. I've often had the same reaction as you. But
usually I calm down and realize that the developers know a lot more than I
do and even though some bugs look like they're simple, often they are not.

Also, I'm not sure why you sent this to the list? Why didn't you just
contact Richard privately? What is it that you want to share with the rest
of us, exactly? Or were you just looking for a third opinion?

Best,

Xu

Re: introduction to programming LyX, anyone?

[Xu Wang]

I agree with you Philip! I have been wanting to write a similar email for a
while. I would love to help develop LyX. In fact, I learned C++ with that
being my primary purpose. But I am still lost when trying to navigate the
code.

I would love for some of the experienced developers to maybe document all
of the steps in particular bug fixes... For example,

1. I knew I had to look in xxx.cpp because... (e.g. I did a grep using the
phrase "yyy")
2. Then I went to the line containing the word xxx
3. Because xxx is of class yyy, I went to yyy.h
4. etc.

Even though every bug is so special, I think that we could learn a lot by
following such documentation.

Thank you!

Xu

Would it be difficult in Qt to allow dragging of elements in the outline
panel? Sometimes it's annoying to keep pushing the "up" or "down" buttons.

ubuntu - an error when I double click on a .lyx flie, but no error when I run from terminal

[Xu Wang]

If I start LyX from the terminal, everything works fine.


But if I just start LyX by double clicking on a .lyx file, then I have
problems (pasted at the end of email). I have tried reconfigure.

Do I have a problem with permissions or something? I don't see why the two
would be different.


I have tried reconfigure and reinstalling and neither has helped.


Here is the error in LyX:

File does not exist: /tmp/lyx_tmpdir.MT6574/lyx_tmpbuf2/testfile.pdf


In the terminal, here is the output:

Systemcall.cpp(238): Systemcall: 'pdflatex  "testfile.tex"' did not start!
Systemcall.cpp(239): error The process failed to start. Either the invoked
program is missing, or you may have insufficient permissions to invoke the
program.
Error: Cannot view file

File does not exist: /tmp/lyx_tmpdir.MT6574/lyx_tmpbuf2/testfile.pdf

I just want to check that I can do the same thing after updating from svn.
Is the following fine?

recompile one .cpp

[Xu Wang]

Hi,

How can I recompile just one of the .cpp and reinstall lyx on ubuntu?

Before, I was doing
make uninstall
make clean
make
sudo make install

But this takes a long time.

See my pitiful attempt below for recompiling one cpp:

xuwang@ubuntu:~/lyx-2.0.x/src$ g++ LaTeX.cpp
LaTeX.cpp:16:20: fatal error: config.h: No such file or directory
compilation terminated.

testing with svn before bug report

[Xu Wang]

Hi,

With all this talk of building testing binaries, I figure I should learn
which versions I should be testing against. Before filing a bug report,
should I test with all of the following?
-the current stable lyx release
-BRANCH_2_0_X
-trunk

If the bug I found is present in some of them but not all what should I do?


I've never used svn. Are these the correct commands to get the latest trunk
and branch?

svn co svn://svn.lyx.org/lyx/lyx-devel/branches/BRANCH_2_0_X lyx-2.0.x

svn co svn://svn.lyx.org/lyx/lyx-devel/trunk lyx-devel

I should have been more precise. I'm interested in learning qt4 for pretty
much the sole purpose of programming for LyX. As I do not know anything
about qt4, I do not know if there are different approaches to learning it,
one of which is more useful for LyX.

I should have been more precise. I'm interested in learning qt4 for pretty
much the sole purpose of programming for LyX. As I do not know anything
about qt4, I do not know if there are different approaches to learning it,
one of which is more useful for LyX.

Qt books

Hi, I would like to learn Qt. I learn much better from physical books than
online resources, although I've heard the Qt manual is very good.

Does anyone have suggestions for me?

How much does Qt change from year to year? I am trying to figure out how new
the book that I look for should be.

Is there any chance that LyX will stop using Qt in the recent future?

I've only studied Accelerated C++ but am thinking of also ordering C++
Primer.

Thank you,

Xu

I like your preferred option as well. However, I'm starting to realize that
such a feature is well over my head, even if I'm willing to spend a lot of
time programming. I need to learn more C++ and Qt4 until I tackle such a
feature so I will have to put it on hold unless anyone else would like to
take the lead.

Thank you very much Cyrille for your suggestions!

Which way would you vote for? I don't know enough about "the LyX way" to be
able to have an opinion.

I disagree. As you pointed out, you can re-export as an svg and then
reimport as an image and you're done. So according to your logic, fixing the
way to copy directly from Inkscape to LyX is not needed, because there is
something else that works. But of course what's the difference with this?
It's the same difference for deciding whether to implement this feature in
LyX or Inkscape: one takes another step (in your case, saving and
reimporting, in my case it would be opening up Inkscape and copying).

Also, there are a lot of people who don't know what vector graphic is, much
less how to edit one. And at my university, LyX is installed and kept up to
date, but we are not allowed to install any other software. Even if we were,
some people do not do this maneuver very often. I don't think they would
want to install another software to do it.

This is a good point. And I think you've almost convinced me that it is an
operation that should be left to a graphics editor. However, I want to point
out that what I am suggesting is not editing. Although a crop achieves the
same thing that I would like to do, this can be done without editing, using
LaTeX directly (as mentioned above with the bounding box or viewport). In
this way, the operation is not a direct graphic-edit. The manipulation would
not have to be WYSIWYG in terms of size, but just in terms of the ratios.
And I think this is more of a WYSIWYM approach.

advice on how to implement my dream LyX feature

[Xu Wang]

I am currently learning C++ programming (from Accelerated C++). There is a
feature that I would like to implement, but I would like some advice as to
1) what I need to know in order to implement it, 2) is it feasible? 3) would
this be useful to others?

Here is the feature:

The user could select a pdf, select a page, and then that page would be
visible in LyX. The user could then draw a rectangle on that pdf page that
would outline the part of that pdf page that he would like to insert into
his lyx document. I think the LaTeX code is not that complicated. It would
just use the bounding box or viewport option of the includegraphics command.
Also, I do not think this falls under the category of "stop requesting that
LyX includes a graphics editor" because it would not even need to access or
edit the image, except to display the pdf page.

Why do I think this would be a good feature?
I see too often documents (both papers and especially beamer presentations)
that would like to put in a table from another pdf, but they do so by taking
a screen shot, which ends up looking quite ugly because its a bitmap.

Any advice would be helpful.

Thank you,

Xu

a guide to LyX source code

[Xu Wang]

Hi,

I am currently learning C++ from Accelerated C++. I know enough to
understand what most chunks of code do. However, I am lost when trying to
navigate through the lyx source code. It seems that grep is my only friend.
I have read the Developing FAQ as well as many pages on the Wiki for
developers.

I would love to see more pages like this, for example:
http://wiki.lyx.org/Devel/NotesOnDispatchMechanism
It walks you through a couple of main ideas and describes the main functions
and
 a few rules on what to do and what not to do.

Are there any other such pages? Have there been any attempts at writing a
"guide
 to the LyX source code" which explains the main files and their connection
with
 one another?

Thank you,

Xu

feature: "page" in import graphics dialog

[Xu Wang]

Sure, the user can put it manually under "LaTeX options" but I think it
would be helpful to have a text box. This way, LyX could also display that
page instead of the first page.

Would this be difficult? My guess is that the text box would not be
difficult, but displaying the correct page would be.

Thank you
