 Hi Jerry,
 Is the document that you are editing exceptionally huge?

No—it is only a few paragraphs of e.g. lorem ipsum or whatever. Adding a few 
equations doesn't seem to make any difference; if anything, it might make 
scrolling faster (not sure) possibly of having less text to render. Also, I 
recall in the LyX docs seeing a page which was a full page of a pre-rendered 
image, and when LyX came to that page, it scrolled faster, then slowing again 
when the pre-rendered page passed.

 I am working on a 100+ pages manuscript with lots of equations and figures 
 without any problem. I am know under Lion on a 2011 MBP,

I wouldn't think Snow Leopard versus Lion would make an difference, but 
_something_ is apparently different between our systems. I think I'm using Qt 
4.7.0. (Is there a 32-bit or 64-bit issue here?)

 but I do not remember having met problems with my Snow Leopard 2008 MBP. But, 
 I have seen in the past some ails about this problem, have you searched the 
 mail list archive? Maybe this is a specific problem for which there could be 
 solutions.

I did a quick check of the archives but didn't see much that I thought was 
relevant.

Re: Image width in figure floats

[Guenter Milde]

On 2012-01-02, Maria Gouskova wrote:

 I want to insert a high-resolution pdf image into a figure float.

I assume this is a bitmap image wrapped into PDF? (For a vector image,
the high-resolution would not make sense to me.)

 I specify the width of the image in the figure properties as 100% of
 line width. Typesetting via pdflatex works fine, with the image scaled
 appropriately. Typesetting via ps2pdf or dvipdfm does not scale the
 image--it spills over onto the margin and off the page.

I cannot reproduce here. Tried inserting a scaled one-page PDF document
(without wrapping in a float). The output of 
PDF (pdflatex),
PDF (ps2pdf), and
PDF (dvipdfm)
is exactly the same (with proper scaling of the indcluded graphic).


 DVI didn't produce a pdf at all, even though LyX claimed successful
 import to pdf.

I don't understand this. (DVI (a file format) didn't produce pdf (a
different file format)?)

 I tried the same with an .eps figure and did not encounter these
 issues, so it seems to be a combination of using a .pdf image and
 certain output formats.

It might also depend on

* the content of the EPS or PDF figure, and
* the PDF - EPS conversion program (as for the ps2pdf route, LyX converts
  the input file from PDF to EPS, latex generates a DVI with a reference to
  the EPS file, dvips embedds it into the generated PS file and ps2pdf
  converts the PS file to PDF).

 I do not think so.

 And I have never seen this and I doubt that this will work because
 without loading the document class or any package, you cannot do much.

There are several use cases. I remember a similar request some time (maybe
years) ago. A hook for pre-documentclass code could also solve some of the
how do I configure auto-loaded packages problems.

I could imagine a layout keyword like

 PrePreamble
   % this should appear before the \documentclass call in the latex source
 EndPrePreamble

This could then be used by layouts like IEEEtranA4 as well as
in idividual documents via the local layout feature.

 But what exactly do you want? Can you send me a _small_ LyX file with a
 short explanation?

 Being able to input code before the \documentclass call is actually not 
 uncommon.

...

 I hope the above explanations are sufficient but I can still submit a 
 LyX file if you want me. I wouldn't be able to show much in it though 
 since this is what I would like LyX to do: allow me to input code before 
 \documentclass :)

In this case, a _small_ LaTeX file might be a better example.

Maybe you can provide some small LaTeX use cases to convince the
developers that this is a case common enought to support it without ugly
workarounds?

 p.s. I'm also using the 2nd example to compile two versions of the same 
 latex document, one with just maths questions (for students), and the 
 other with questions+answers (for supervisors). Saves time, different 
 issue though.

In LyX, conditional text is usually done with branches 
(define with DocumentSettingsBranches, use with InsertBranch).

 It would be quite nice if LyX offered a feature to edit, say, the source

 source, a separate window/panel appears with the source, do my edits 
 there e.g. add \\[10pt], press done to go back to normal LyX view. I 
 know it looks like it defeats the purpose of LyX but would allow quick 
 workarounds of any troublesome situations.

 What do others think?

My suggestion is to allow dissolution of a math inset similar to other
insets (note, float, minipages and other boxes, etc.):
  
  if you place the cursor at the first position in the inset and press
  Backspace, the inset is replaced by its content.
  
For a math-inset, the content would be the LaTeX source. Then you could
toggle between source and math-inset quite easily.

Of course, an editable LaTeX source view would be the more generic and long
awaited solution - but far more hard to implement.

Hi Jerry,

seems I was the only person to see it, although I could see it on 2 
machines (different OS versions of windows, different CPU different 
graphic cards). So I am somehow glad it's happening to you (sorry).


I did not have that problem with LyX 2.0.1, so I would advise to try

Just remove the affected files (which have conflicts) or all *.po* files. If

after the update.

Alternatively, you can also issue svn revert -R * from within the po

After removing all the .po files and nothing else from the po dir the

However, the lyx help shows still version 2.0.1 instead of 2.0.2.

What else do I have to do to get the latest version?

Hi,

I'm almost sure it depends on Qt-Version.

With LyX on Mac with Qt4 we have two fundamental problems:
1. Qt4 with Carbon crashes when interacting with some desktop tools like Divvy 
or SizeUp
http://www.lyx.org/trac/ticket/7365 and
http://www.lyx.org/trac/ticket/7519

2. Qt4 with Cocoa is painting text with kerning hints
This doesn't match with the drawing engine of LyX and LyX's cursor movement.
See the discussion here: 
http://www.mail-archive.com/lyx-devel@lists.lyx.org/msg169152.html

I've build 2.0.2 on Mac with Qt4.7 where Cocoa is the default to avoid (1).
The drawback is we have to deal with (2) - the current solution is to draw text 
just char by char,
the text fragments are only one character long.

To check if this is the culprit one may add the following line to your 
preferences file:
\force_paint_single_char false
On a Mac this is the file ~/Library/Application Support/LyX-2.0/preferences.
(Broken cursor placement for long lines should be one consequence.)

Beamer (elabeling) list and \uncover overlay

[Wolfgang Keller]

Hello,

in a beamer presentation (see attached minimal example), I want to
uncover a (labelled) list line by line, _including_ the labels for each
line. If I place the ERT with \uncoveri-{ in front of the label, this
yields an error due to mismatching of ] and }.

How do I place the ERT with \uncoveri-{ in front of the (invisible)
\item, so that the label does also get uncovered?

In TeXworks, this is easy, but in LyX, it seems to be essentially
impossible.


TIA,

Sincerely,

Wolfgang

Hi Jerry,

I also see the symptom you describe on a 110K word book in LyX, 
rendered in LyX 2.0.0 on Ubuntu Linux 11.04 on a 3 year old desktop 
with an Intel dual core. If I scroll by dragging the vertical 
scrollbar, it goes in jumps. If I use my mouse wheel, it seems a 
little slow there too. PageDown is not without its delays.

I've never noticed this problem before, even though I've written 
almost ten books in LyX. The reason I never noticed it is I seldom 
have a reason to scroll through significant parts of the book. If I'm 
looking for something, I can either find it drilling down via outline 
view, or use text search to find it. The only time I scroll is when I 
expect the needed text to be within a couple pagefulls of where I am 
now.

Also, Ctrl+Home and Ctrl+End can be used to go to the Beginning/End of 
the document, in less than 1/4 second. You can also set and goto up to 
9 bookmarks with hotkeys.

Bottom line, I reproduced the symptom you mentioned, but other LyX 
features make it not the slightest bit of a problem.

It is indeed a vector format pdf file generated in R, sorry about not
making sense to you with my explanation.

 I specify the width of the image in the figure properties as 100% of
 line width. Typesetting via pdflatex works fine, with the image scaled
 appropriately. Typesetting via ps2pdf or dvipdfm does not scale the
 image--it spills over onto the margin and off the page.

 I cannot reproduce here. Tried inserting a scaled one-page PDF document
 (without wrapping in a float). The output of
 PDF (pdflatex),
 PDF (ps2pdf), and
 PDF (dvipdfm)
 is exactly the same (with proper scaling of the indcluded graphic).

Okay. Are your OS and LyX version the same?

 DVI didn't produce a pdf at all, even though LyX claimed successful
 import to pdf.

 I don't understand this. (DVI (a file format) didn't produce pdf (a
 different file format)?)

Sorry, DVI produced an output, not a pdf file, obviously. That was a typo.

 I tried the same with an .eps figure and did not encounter these
 issues, so it seems to be a combination of using a .pdf image and
 certain output formats.

 It might also depend on

 * the content of the EPS or PDF figure, and
 * the PDF - EPS conversion program (as for the ps2pdf route, LyX converts
  the input file from PDF to EPS, latex generates a DVI with a reference to
  the EPS file, dvips embedds it into the generated PS file and ps2pdf
  converts the PS file to PDF).

Well, what I find interesting is that the output methods work equally
well when I specify the size of the figure as a percentage of the
original file (e.g., 40%), but not when I specify it as being 100% of
the line width.

Anyway, I have a sort of workaround, even though I do not have a
solution. Thanks for your response.

Hmmm. I suspect that the problem is worse on my machine because even scrolling

easily noticeable/annoying--hard to track features as they go by.

Scrolling large distances in a short time pretty much takes place as fast as 
scrolling a native application; it's just that to get the job done in roughly 
the same amount of time, there are huge jumps.

In an earlier post in this thread I noted that 2.0.1 was much better in this

looks like a recent development.

Re: UserDir Ui settings NOT overriding LyXDir Ui setting

Richard: I tried erasing the ~/.lyx dir, but nothing changes, same
behavior. I forgot to mention that the default ui I get is with three
toolbars (Standard, View/Update, Extra), two of which, however, are
almost completely hidden (see picture below). So it looks like it's
some configuration problem, perhaps on Archlinux only.

Guenter: I am not sure about what you mean by UI flavour. Is it the
choice of Default Classic, and Oxygen in ToolsPreferences
Look and Feel User interface? I tried selecting either classic or
oxygen but nothing seems to change.

 Hi,
 
 Check my 2 messages in the LyX 2.0.2 Released thread, one dated december 
 5th (user mailing lists, perhaps devel too) and the other one dated december 
 16th (devel ML), which contains more details:

 Hi,
 
 I'm almost sure it depends on Qt-Version.
 
 With LyX on Mac with Qt4 we have two fundamental problems:
 1. Qt4 with Carbon crashes when interacting with some desktop tools like 
 Divvy or SizeUp
 http://www.lyx.org/trac/ticket/7365 and
 http://www.lyx.org/trac/ticket/7519
 
 2. Qt4 with Cocoa is painting text with kerning hints
 This doesn't match with the drawing engine of LyX and LyX's cursor movement.
 See the discussion here: 
 http://www.mail-archive.com/lyx-devel@lists.lyx.org/msg169152.html
 
 I've build 2.0.2 on Mac with Qt4.7 where Cocoa is the default to avoid (1).
 The drawback is we have to deal with (2) - the current solution is to draw 
 text just char by char,
 the text fragments are only one character long.
 
 To check if this is the culprit one may add the following line to your 
 preferences file:
 \force_paint_single_char false
 On a Mac this is the file ~/Library/Application Support/LyX-2.0/preferences.
 (Broken cursor placement for long lines should be one consequence.)

I've added the line that you suggest and the scrolling is improved--much like 
or exactly like 2.0.1 scrolling that I commented on earlier in this thread. And 
I see no problem with an incorrectly placed cursor.

I do not think so.

And I have never seen this and I doubt that this will work because
without loading the document class or any package, you cannot do much.

There are several use cases. I remember a similar request some time
(maybe
years) ago. A hook for pre-documentclass code could also solve some
of the
how do I configure auto-loaded packages problems.

I could imagine a layout keyword like

PrePreamble
% this should appear before the \documentclass call in the latex source
EndPrePreamble

This could then be used by layouts like IEEEtranA4 as well as
in idividual documents via the local layout feature.

If this is definitely needed, it is easy to provide it. Adding Layout
stuff is fairly trivial. I guess the question was: Do we need it? or is
there some other way around this?

Richard


I guess the need question depends on the time and attitude of the 
devs. I agree that most users probably do not need it and then you as 
devs may argue that you don't want to bother for a minority. However, 
LyX is a truly great piece of software and would be nice to cover all 
user base, not just the majority (granted, the latter could be 
overwhelming).


I for one needed this fairly often for the IEEEtran class. In a reply to 
this thread I pointed to the official IEEEtran FAQ which requires code 
before \documentclass{} in order to set page margins: 
http://article.gmane.org/gmane.editors.lyx.general/73642


I also found older requests for this in the LyX list from users that 
were in the same situation: 
http://article.gmane.org/gmane.editors.lyx.general/50299


In my previous reply to this topic, I provided a hack that makes it 
possible (converter wrapper that parses and replaces the .tex output of 
LyX on the fly based on a placeholder in the LyX document class options 
before passing it to pdflatex). I did it in a matter of minutes so I 
believe (or want to believe) that it's trivial for the devs to add an 
extra text field next to the document class options field for code that 
goes before \documentclass{}.


See my hack here: http://article.gmane.org/gmane.editors.lyx.general/73663

In this case, a _small_ LaTeX file might be a better example.

Maybe you can provide some small LaTeX use cases to convince the

 p.s. I'm also using the 2nd example to compile two versions of the same

In LyX, conditional text is usually done with branches

My suggestion is to allow dissolution of a math inset similar to other
insets (note, float, minipages and other boxes, etc.):
  
  if you place the cursor at the first position in the inset and press
  Backspace, the inset is replaced by its content.
  
For a math-inset, the content would be the LaTeX source. Then you could

Of course, an editable LaTeX source view would be the more generic and long

Hi Jerry,

I reported the very same sysmptoms a few weeks ago but until now it 
seems I was the only person to see it, although I could see it on 2 
machines (different OS versions of windows, different CPU different 
graphic cards). So I am somehow glad it's happening to you (sorry).


I did not have that problem with LyX 2.0.1, so I would advise to try 
that version instead and report if it fixes the issue for you too.

Just remove the affected files (which have conflicts) or all *.po* files. If 
you remove the whole dir, you will need to rerun ./autogen.sh and configure 
after the update.

Alternatively, you can also issue svn revert -R * from within the po

After removing all the .po files and nothing else from the po dir the 
svn update went smoothly.

However, the lyx help shows still version 2.0.1 instead of 2.0.2.

What else do I have to do to get the latest version?

The version number gets updated at configure time IIRC. So try ./configure ;

I do not think so.

And I have never seen this and I doubt that this will work because
without loading the document class or any package, you cannot do much.

There are several use cases. I remember a similar request some time (maybe
years) ago. A hook for pre-documentclass code could also solve some of the
how do I configure auto-loaded packages problems.

I could imagine a layout keyword like

  PrePreamble
% this should appear before the \documentclass call in the latex source
  EndPrePreamble

This could then be used by layouts like IEEEtranA4 as well as
in idividual documents via the local layout feature.
If this is definitely needed, it is easy to provide it. Adding Layout 
stuff is fairly trivial. I guess the question was: Do we need it? or is 
there some other way around this?

I think a prefix for different branch versions is overkill, the changes should

Hi,

I'm almost sure it depends on Qt-Version.

With LyX on Mac with Qt4 we have two fundamental problems:
1. Qt4 with Carbon crashes when interacting with some desktop tools like Divvy 
or SizeUp
http://www.lyx.org/trac/ticket/7365 and
http://www.lyx.org/trac/ticket/7519

2. Qt4 with Cocoa is painting text with kerning hints
This doesn't match with the drawing engine of LyX and LyX's cursor movement.
See the discussion here: 
http://www.mail-archive.com/lyx-devel@lists.lyx.org/msg169152.html

I've build 2.0.2 on Mac with Qt4.7 where Cocoa is the default to avoid (1).
The drawback is we have to deal with (2) - the current solution is to draw text 
just char by char,
the text fragments are only one character long.

To check if this is the culprit one may add the following line to your 
preferences file:
\force_paint_single_char false
On a Mac this is the file ~/Library/Application Support/LyX-2.0/preferences.
(Broken cursor placement for long lines should be one consequence.)

Beamer (elabeling) list and \uncover overlay

[Wolfgang Keller]

Hello,

in a beamer presentation (see attached minimal example), I want to
uncover a (labelled) list line by line, _including_ the labels for each
line. If I place the ERT with \uncoveri-{ in front of the label, this
yields an error due to mismatching of ] and }.

How do I place the ERT with \uncoveri-{ in front of the (invisible)
\item, so that the label does also get uncovered?

In TeXworks, this is easy, but in LyX, it seems to be essentially
impossible.


TIA,

Sincerely,

Wolfgang

Hello,

and yet another issue with beamer and LyX:

Somehow, the list item bullets in the attached document get lost when
compiling to PDF. And this seems to be independent of whether I use
XeTeX or not.

Any idea what I have overseen?

TIA,

Hi Jerry,

I also see the symptom you describe on a 110K word book in LyX, 
rendered in LyX 2.0.0 on Ubuntu Linux 11.04 on a 3 year old desktop 
with an Intel dual core. If I scroll by dragging the vertical 
scrollbar, it goes in jumps. If I use my mouse wheel, it seems a 
little slow there too. PageDown is not without its delays.

I've never noticed this problem before, even though I've written 
almost ten books in LyX. The reason I never noticed it is I seldom 
have a reason to scroll through significant parts of the book. If I'm 
looking for something, I can either find it drilling down via outline 
view, or use text search to find it. The only time I scroll is when I 
expect the needed text to be within a couple pagefulls of where I am 
now.

Also, Ctrl+Home and Ctrl+End can be used to go to the Beginning/End of 
the document, in less than 1/4 second. You can also set and goto up to 
9 bookmarks with hotkeys.

Bottom line, I reproduced the symptom you mentioned, but other LyX 
features make it not the slightest bit of a problem.

 I assume this is a bitmap image wrapped into PDF? (For a vector image,

It is indeed a vector format pdf file generated in R, sorry about not
making sense to you with my explanation.

 I specify the width of the image in the figure properties as 100% of
 line width. Typesetting via pdflatex works fine, with the image scaled
 appropriately. Typesetting via ps2pdf or dvipdfm does not scale the
 image--it spills over onto the margin and off the page.

 I cannot reproduce here. Tried inserting a scaled one-page PDF document
 (without wrapping in a float). The output of
 PDF (pdflatex),
 PDF (ps2pdf), and
 PDF (dvipdfm)
 is exactly the same (with proper scaling of the indcluded graphic).

Okay. Are your OS and LyX version the same?

 DVI didn't produce a pdf at all, even though LyX claimed successful
 import to pdf.

 I don't understand this. (DVI (a file format) didn't produce pdf (a
 different file format)?)

Sorry, DVI produced an output, not a pdf file, obviously. That was a typo.

 I tried the same with an .eps figure and did not encounter these
 issues, so it seems to be a combination of using a .pdf image and
 certain output formats.

 It might also depend on

 * the content of the EPS or PDF figure, and
 * the PDF - EPS conversion program (as for the ps2pdf route, LyX converts
  the input file from PDF to EPS, latex generates a DVI with a reference to
  the EPS file, dvips embedds it into the generated PS file and ps2pdf
  converts the PS file to PDF).

Well, what I find interesting is that the output methods work equally
well when I specify the size of the figure as a percentage of the
original file (e.g., 40%), but not when I specify it as being 100% of
the line width.

Anyway, I have a sort of workaround, even though I do not have a
solution. Thanks for your response.

Hmmm. I suspect that the problem is worse on my machine because even scrolling 
small amounts (a few lines or a couple of pages) is so laggy/jumpy that it is 
easily noticeable/annoying--hard to track features as they go by.

Scrolling large distances in a short time pretty much takes place as fast as 
scrolling a native application; it's just that to get the job done in roughly 
the same amount of time, there are huge jumps.

In an earlier post in this thread I noted that 2.0.1 was much better in this 
regard (I just tried 2.0.1 a couple hours ago), so at least in part, this is 
looks like a recent development.

Re: UserDir Ui settings NOT overriding LyXDir Ui setting

[stefano franchi]

Richard: I tried erasing the ~/.lyx dir, but nothing changes, same
behavior. I forgot to mention that the default ui I get is with three
toolbars (Standard, View/Update, Extra), two of which, however, are
almost completely hidden (see picture below). So it looks like it's
some configuration problem, perhaps on Archlinux only.

Guenter: I am not sure about what you mean by UI flavour. Is it the
choice of Default Classic, and Oxygen in ToolsPreferences
Look and Feel User interface? I tried selecting either classic or
oxygen but nothing seems to change.

Cheers,

Stefano

 Hi,
 
 Check my 2 messages in the LyX 2.0.2 Released thread, one dated december 
 5th (user mailing lists, perhaps devel too) and the other one dated december 
 16th (devel ML), which contains more details:
 
 http://www.mail-archive.com/lyx-users@lists.lyx.org/msg90218.html

 Hi,
 
 I'm almost sure it depends on Qt-Version.
 
 With LyX on Mac with Qt4 we have two fundamental problems:
 1. Qt4 with Carbon crashes when interacting with some desktop tools like 
 Divvy or SizeUp
 http://www.lyx.org/trac/ticket/7365 and
 http://www.lyx.org/trac/ticket/7519
 
 2. Qt4 with Cocoa is painting text with kerning hints
 This doesn't match with the drawing engine of LyX and LyX's cursor movement.
 See the discussion here: 
 http://www.mail-archive.com/lyx-devel@lists.lyx.org/msg169152.html
 
 I've build 2.0.2 on Mac with Qt4.7 where Cocoa is the default to avoid (1).
 The drawback is we have to deal with (2) - the current solution is to draw 
 text just char by char,
 the text fragments are only one character long.
 
 To check if this is the culprit one may add the following line to your 
 preferences file:
 \force_paint_single_char false
 On a Mac this is the file ~/Library/Application Support/LyX-2.0/preferences.
 (Broken cursor placement for long lines should be one consequence.)

I've added the line that you suggest and the scrolling is improved--much like 
or exactly like 2.0.1 scrolling that I commented on earlier in this thread. And 
I see no problem with an incorrectly placed cursor.

There are several use cases. I remember a similar request some time

I guess the need question depends on the time and attitude of the 
devs. I agree that most users probably do not need it and then you as 
devs may argue that you don't want to bother for a minority. However, 
LyX is a truly great piece of software and would be nice to cover all 
user base, not just the majority (granted, the latter could be 
overwhelming).


I for one needed this fairly often for the IEEEtran class. In a reply to 
this thread I pointed to the official IEEEtran FAQ which requires code 
before \documentclass{} in order to set page margins: 
http://article.gmane.org/gmane.editors.lyx.general/73642


I also found older requests for this in the LyX list from users that 
were in the same situation: 
http://article.gmane.org/gmane.editors.lyx.general/50299


In my previous reply to this topic, I provided a hack that makes it 
possible (converter wrapper that parses and replaces the .tex output of 
LyX on the fly based on a placeholder in the LyX document class options 
before passing it to pdflatex). I did it in a matter of minutes so I 
believe (or want to believe) that it's trivial for the devs to add an 
extra text field next to the document class options field for code that 
goes before \documentclass{}.

No—it is only a few paragraphs of e.g. "lorem ipsum" or whatever. Adding a few 
equations doesn't seem to make any difference; if anything, it might make 
scrolling faster (not sure) possibly of having less text to render. Also, I 
recall in the LyX docs seeing a page which was a full page of a pre-rendered 
image, and when LyX came to that page, it scrolled faster, then slowing again 
when the pre-rendered page passed.

I wouldn't think Snow Leopard versus Lion would make an difference, but 
_something_ is apparently different between our systems. I think I'm using Qt 
4.7.0. (Is there a 32-bit or 64-bit issue here?)

I cannot reproduce here. Tried inserting a scaled one-page PDF document
(without wrapping in a float). The output of 
PDF (pdflatex),
PDF (ps2pdf), and
PDF (dvipdfm)
is exactly the same (with proper scaling of the indcluded graphic).

I don't understand this. (DVI (a file format) didn't produce pdf (a
different file format)?)

It might also depend on

* the content of the EPS or PDF figure, and
* the PDF -> EPS conversion program (as for the ps2pdf route, LyX converts
  the input file from PDF to EPS, latex generates a DVI with a reference to
  the EPS file, dvips embedds it into the generated PS file and ps2pdf
  converts the PS file to PDF).

In this case, a _small_ LaTeX file might be a better example.

Maybe you can provide some small LaTeX use cases to convince the

In LyX, conditional text is usually done with branches 
(define with Document>Settings>Branches, use with Insert>Branch).

My suggestion is to allow "dissolution" of a math inset similar to other
insets (note, float, minipages and other boxes, etc.):
  
  if you place the cursor at the first position in the inset and press
  Backspace, the inset is replaced by its content.
  
For a math-inset, the content would be the LaTeX source. Then you could
toggle between source and math-inset quite easily.

Of course, an editable LaTeX source view would be the more generic and long
awaited solution - but far more hard to implement.

Hi Jerry,

seems I was the only person to see it, although I could see it on 2 
machines (different OS versions of windows, different CPU different

I did not have that problem with LyX 2.0.1, so I would advise to try 
that version instead and report if it fixes the issue for you too.

Just remove the affected files (which have conflicts) or all *.po* files. If 
you remove the whole dir, you will need to rerun ./autogen.sh and configure 
after the update.

Alternatively, you can also issue "svn revert -R *" from within the po 
directory.

Thanks again, Jürgen

After removing all the .po files and nothing else from the po dir the 
svn update went smoothly.

However, the lyx help shows still version 2.0.1 instead of 2.0.2.

What else do I have to do to get the latest version?

The version number gets updated at configure time IIRC. So try ./configure ; 
make. If this doesn't help, you might even have to run ./autogen.sh in 
advance.

Thanks again, Juergen and Richard, 
sorry that I forgot to configure make 

when doing make and make check, I get this error:

make[3]: Entering directory `/mnt/sda/home/wolfgang/lyx-devel/src'

does it mean, I have to make clean and run first ./autogen.sh ?

and make install prefix=/usr/local/stow/lyx202 
might be wise, to have the old 2.0.1 available if something goes wrong ?

I think a prefix for different branch versions is overkill, the changes should 
be bearable. And you can always just reinstall 2.0.1 if things go wrong.

Hi,

I'm almost sure it depends on Qt-Version.

With LyX on Mac with Qt4 we have two fundamental problems:
1. Qt4 with Carbon crashes when interacting with some desktop tools like Divvy 
or SizeUp
http://www.lyx.org/trac/ticket/7365 and
http://www.lyx.org/trac/ticket/7519

2. Qt4 with Cocoa is painting text with kerning hints
This doesn't match with the drawing engine of LyX and LyX's cursor movement.
See the discussion here: 
http://www.mail-archive.com/lyx-devel@lists.lyx.org/msg169152.html

I've build 2.0.2 on Mac with Qt4.7 where Cocoa is the default to avoid (1).
The drawback is we have to deal with (2) - the current solution is to draw text 
just char by char,
the text fragments are only one character long.

To check if this is the culprit one may add the following line to your 
preferences file:
\force_paint_single_char false
On a Mac this is the file "~/Library/Application Support/LyX-2.0/preferences".
(Broken cursor placement for long lines should be one consequence.)

Beamer (elabeling) list and \uncover overlay

[Wolfgang Keller]

Hello,

in a beamer presentation (see attached minimal example), I want to
uncover a (labelled) list line by line, _including_ the labels for each
line. If I place the ERT with \uncover{ in front of the label, this
yields an error due to mismatching of ] and }.

How do I place the ERT with \uncover{ in front of the (invisible)
\item, so that the label does also get uncovered?

In TeXworks, this is easy, but in LyX, it seems to be essentially
impossible.


TIA,

Sincerely,

Wolfgang

Hello,

and yet another issue with beamer and LyX:

Somehow, the list item bullets in the attached document get lost when
compiling to PDF. And this seems to be independent of whether I use
XeTeX or not.

Any idea what I have overseen?

I just downloaded 2.0.1. The scrolling with that version is better, bordering 
on useful (or better). It is still sluggish but generally not horrible. 
(Nowhere as fast as native OS X scrolling.) Maybe a factor of 2x(?) faster.

Hi Jerry,

I also see the symptom you describe on a 110K word book in LyX, 
rendered in LyX 2.0.0 on Ubuntu Linux 11.04 on a 3 year old desktop 
with an Intel dual core. If I scroll by dragging the vertical 
scrollbar, it goes in jumps. If I use my mouse wheel, it seems a 
little slow there too. PageDown is not without its delays.

I've never noticed this problem before, even though I've written 
almost ten books in LyX. The reason I never noticed it is I seldom 
have a reason to scroll through significant parts of the book. If I'm 
looking for something, I can either find it drilling down via outline 
view, or use text search to find it. The only time I scroll is when I 
expect the needed text to be within a couple pagefulls of where I am 
now.

Also, Ctrl+Home and Ctrl+End can be used to go to the Beginning/End of 
the document, in less than 1/4 second. You can also set and goto up to 
9 bookmarks with hotkeys.

Bottom line, I reproduced the symptom you mentioned, but other LyX 
features make it not the slightest bit of a problem.

It is indeed a vector format pdf file generated in R, sorry about not

Okay. Are your OS and LyX version the same?

Sorry, DVI produced an output, not a pdf file, obviously. That was a typo.

Well, what I find interesting is that the output methods work equally
well when I specify the size of the figure as a percentage of the
original file (e.g., 40%), but not when I specify it as being 100% of
the line width.

Anyway, I have a sort of workaround, even though I do not have a
solution. Thanks for your response.

Hmmm. I suspect that the problem is worse on my machine because even scrolling 
small amounts (a few lines or a couple of pages) is so laggy/jumpy that it is 
easily noticeable/annoying--hard to track features as they go by.

Scrolling large distances in a short time pretty much takes place as fast as 
scrolling a native application; it's just that to get the job done in roughly 
the same amount of time, there are huge jumps.

In an earlier post in this thread I noted that 2.0.1 was much better in this 
regard (I just tried 2.0.1 a couple hours ago), so at least in part, this is 
looks like a recent development.

Re: UserDir Ui settings NOT overriding LyXDir Ui setting

[stefano franchi]

Richard: I tried erasing the ~/.lyx dir, but nothing changes, same
behavior. I forgot to mention that the default ui I get is with three
toolbars (Standard, View/Update, Extra), two of which, however, are
almost completely hidden (see picture below). So it looks like it's
some configuration problem, perhaps on Archlinux only.

Guenter: I am not sure about what you mean by "UI flavour." Is it the

I've added the line that you suggest and the scrolling is improved--much like 
or exactly like 2.0.1 scrolling that I commented on earlier in this thread. And 
I see no problem with an incorrectly placed cursor.

I do not think so.

And I have never seen this and I doubt that this will work because
without loading the document class or any package, you cannot do much.

There are several use cases. I remember a similar request some time
(maybe
years) ago. A "hook" for pre-documentclass code could also solve some
of the
"how do I configure auto-loaded packages" problems.

I could imagine a layout keyword like

PrePreamble
% this should appear before the \documentclass call in the latex source
EndPrePreamble

This could then be used by layouts like "IEEEtranA4" as well as
in idividual documents via the local layout feature.

If this is definitely needed, it is easy to provide it. Adding Layout
stuff is fairly trivial. I guess the question was: Do we need it? or is
there some other way around this?

Richard


I guess the "need" question depends on the time and attitude of the 
devs. I agree that most users probably do not need it and then you as 
devs may argue that you don't want to bother for a minority. However, 
LyX is a truly great piece of software and would be nice to cover all 
user base, not just the majority (granted, the latter could be 
overwhelming).


I for one needed this fairly often for the IEEEtran class. In a reply to 
this thread I pointed to the official IEEEtran FAQ which requires code 
before \documentclass{} in order to set page margins: 
http://article.gmane.org/gmane.editors.lyx.general/73642


I also found older requests for this in the LyX list from users that 
were in the same situation: 
http://article.gmane.org/gmane.editors.lyx.general/50299


In my previous reply to this topic, I provided a hack that makes it 
possible (converter wrapper that parses and replaces the .tex output of 
LyX on the fly based on a placeholder in the LyX document class options 
before passing it to pdflatex). I did it in a matter of minutes so I 
believe (or want to believe) that it's trivial for the devs to add an 
extra text field next to the document class options field for code that
