No, that patch doesn't work. See attachment for what it gives me

BTW, the patch says:

case '~':

 break;
 
 case '^':

Shouldn't both values added to column-variable be 3, instead of 16 and 17?
Anyway, I tried that too, but it doesn't solve my problem either.

Well you did read my comment on bug #44 in lyxbugs, didn't you? But I know
you're busy (as I am) so I explain it to you another time. Normally LyX put's
the cursor before the specified position (there is one exeption). In the
case of a NeedFullRow or displayed inset we want to set the cursor NOT in
front of the inset but at the end of the row before (if it is of the same
paragraph!), BUT we need the y position of the original position as otherwise
when we enter the inset we have a wrong outside y() and the insetcursor depends
on it, therefor for the inset we need the y position BEFORE the inset!
Explained well enough?

| +y -= (text.cursor.iy());
 
 feel free to remove the parantesis as well.

Sure

 I do not understand the comment.

Well it should say the y positon before the inset or something like that feel
free to give me a better short description for it.

 I hate variables just called flag, what is this a flag for? What does
 it mean?

Me too but it is really obvious for what it is needed and the function is
really short!

 should it really have been called
 there_is_a_space_on_the_last_posisiton?

no it should be

ignore_the_space_on_the_last_position

 If it fix the problem then ok... 

It fixes it but we have one more (but it is VERY unlikely someone discovered
it. It only happens if you have one or more full rows with ONLY chars
(no separators), try it and then try to press the End button and look where
the cursor goes ;)

But as I said it's very unlikely that someone sees this and it still puts the
inserted char in the right row, not like with the inset that it has the cursor
in the row below and inserts chars in the row above.

Well I commit it then!

No, an argument would be a single inset , which can be either a
single token (character, anything that make sense) or a `box inset'. A
`box inset' is an inset which contains a string of math insets.

Andre How should editing work when you want to change a_i to a_{ij}?

Using your award-winning (and patent pending) method of selecting the
'i' and using math-box-insert, which would create a box with i in it.

center woes

   \includegraphics[height=0.8172in, width=2.9084in]{Weg3.eps}%
   \caption{Nonisomorphic trees with four vertices}%

  \latex latex 
  \backslash includegraphics[height=0.8172in, width=2.9084in]{Weg3.eps}
  \latex default 

  \layout Caption
  \align center 
  Nonisomorphic trees with four vertices

  \layout Standard
  \end_float 

The problem is the '\align center' in the caption that gets read in
and displayed properly by LyX but is written to LaTeX as  

  \caption{\begin{center} ... \end{center}}

(and of course LaTeX chokes on that)

I seem unable to create such a situation from within LyX proper, but this
seriously hampers co-operation with users of Scientific Workplace, since
that's what they produce...

Guess what. We already have MathBraceInset, which are MathNestInsets with a
single cell (MathArray) that get written to LaTeX as '{', contents, '}'.

So we could reformulate this as:

Currently:

 MathFracInset == MathNestInset with two MathArrays
 MathArray == vectorMathAtom
 MathAtom  == smartpointerMathInset

Is this what you want:

 MathFracInset  == MathNestInset with two MathAtoms
 MathAtom   == smartpointerMathInset
 MathBraceInset == some special Mathinset == vectorMathAtom

?

This would look feasible. And it would actually memory usage a bit since a
MathAtom is smaller than a MathArray with one entry...

Andre == smartpointerMathInset MathBraceInset == some special
Andre Mathinset == vectorMathAtom

Andre ?

Yes, something like this.

Andre This would look feasible. And it would actually memory usage a
Andre bit since a MathAtom is smaller than a MathArray with one
Andre entry...

The problem first is to know whether it is desirable :) I cannot guess
what all the implications of this might be. But I think that with
current mathed, one has to use space much too often for fast typing.

Dekel,

I have modified the line as follows:

  PassThru  1
  CopyStyle Affiliation
  LatexName email
  LabelString   Electronic Address: 

  TextFont
Family  Typewriter
  EndFont
  LabelFont
# override Typewriter
Family  Roman
  EndFont
End

Style Author_URL
  PassThru  1
  CopyStyle Author Email
  LatexName homepage
  LabelString   URL:

[...]

To no avail :(.

I still get the litteral text \textasciitilde{} in my final output.
I also tried with Typewriter replaced by Roman, but also that
did not help.

Any other ideas?

Thanks,
Rob.

Well... it's a fairly fundamental blow to the current architecture.

Getting it compiled should be easy, however. The real problem will be to
get editing and navigation working again, and quite a few people won't
like it because it will be different...

 But I think that with current mathed, one has to use space much too

Maybe our usage patterns differ.

Jug,

I can fix the cursor placement by commenting out line 570 in insetert.C 
(InsetERT::draw):

if (!isOpen()) {
draw_collapsed(pain, baseline, x);
// x += TEXT_TO_INSET_OFFSET;  -- this one!
return;

But don't ask me why I did this ;-)

Give insets a full Row

[Juergen Vigna]

The attached small patch changes LyX's behaviour for NeedFullRow insets in
that it does give them ALWAYS the full row for drawing and does not care if
there is some indent or depth. IMO this is correct and should be done, also
this fixes a few problems we have and makes things easier to handle.

Comments!?

Graphics: file loading problems

[R. Lahaye]

Hi,

I have attached a tar file that contains an example lyx-file
and a graphics file, that hopefully demonstrate the problem.

Please start LyX-CVS from beginning (don't use an already
running LyX) and open the attached GraphicsTest.lyx, which
has figures/MyGraph.jpg as a graphics-float inset.

All you need to do is: View-DVI, which will generate an error.

See the attached png files for my LyX-canvas and the LaTeX-Error
window.
(sorry for all attachments, don't know howelse to show this).

Can you reproduce this error?
If so, please notice that in the process LyX generates a file 
figures/MyGraph.eps. This shouldn't happen, should it?

But since we now have that eps file there, please open next
the graphics dialog and change the filename to the eps file.
All of a sudden View-DVI works fine!

There is something wrong here with non-(e)ps files.

Am I the only one experiencing this?

Regards,
Rob.

Forget it. This is caused by KDE (when you start lyx from a desktop icon and 
the mouse pointer is over the lyx window, the splash screen disappears).

No, that patch doesn't work. See attachment for what it gives me

Shouldn't both values added to column-variable be 3, instead of 16 and 17?

Any more ideas how to solve this tilde/circum problem ?

It seems to occur only with the "Author Email" and "Auther URL"

Well you did read my comment on bug #44 in lyxbugs, didn't you? But I know
you're busy (as I am) so I explain it to you another time. Normally LyX put's
the cursor "before" the specified position (there is one exeption). In the
case of a NeedFullRow or displayed inset we want to set the cursor NOT in
front of the inset but at the end of the row before (if it is of the same
paragraph!), BUT we need the y position of the original position as otherwise
when we enter the inset we have a wrong outside y() and the insetcursor depends
on it, therefor for the inset we need the y position BEFORE the inset!
Explained well enough?

Well it should say the y positon before the inset or something like that feel

It fixes it but we have one more (but it is VERY unlikely someone discovered
it. It only happens if you have one or more full rows with ONLY chars
(no separators), try it and then try to press the "End" button and look where
the cursor goes ;)

But as I said it's very unlikely that someone sees this and it still puts the
inserted char in the right row, not like with the inset that it has the cursor
in the row below and inserts chars in the row above.

Well I commit it then!

OK.

Andre> PS: BTW how often do you use \macrowithoutarg{ ?

This is not the problem I had in mind. Assume there is a macros \foo
which takes an argument and which for some reason is not known to
mathed. When I type \foo{, I'd like to have the red braces. But
obviously, if I type, say, \sqrt{, I do not expect to have the braces,
since they are already provided by mathed.

Anyway, I thought about a different thing this morning (for later :).
In mathed you have some macros which only have a scope of one
character (like font changes), while most of them create a box, from
which you have to exit later. The (La)TeX behaviour is different: by
default, arguments are only one token, unless you add explicit braces
(add a box, in mathed terms). Why couldn't mathed have the same
behaviour? This makes simple formulas much easier to enter (a_i+b_i
vs. a_i+b_i) and would probably be intuitive to use. If
you want to have a longer subscript you can add a box, for example
with a lfun bound to (surprise!) the key {.

Does it make sense?

Please remember that I once managed to convince you to do something about

Sorry, but I myself am totally ignorant about fonts and related stuff.

Is the font selected due to my own personal settings or is that
fixed in the REVTeX-4 class file? I have no idea where to look for this!

If this is really relevant, please tell me how to find out about
what fonts I'm using and how I can fix it.

I have a strong feeling that mathed will get more aware of macro arguments
during the 1.3 series and I think we might 'fix' this then. Consider filing
a feature request on bugzilla.

Yes, but I don't think I want implement this. We would need a 'stateful
cursor' again to distiguish between '{' pressed or not, and editing
probably would get a mess again. How should editing work when you want to
change  a_i  to a_{ij}?

No you don't.  If '{' is not pressed, the cursor is in a 'single char
subscript'. If '{' is pressed, the cursor is in a full blown box math
(inset). So the cursor's state is expressed by where it is?

[For the record: Everything in math is an 'inset', the boxes are 'cells' of
a 'nestinset' which is a special type of 'inset' which can have, well,
'nested cells']

This would mean some extra inset for 'one char superscripts'?

Yes but he's still right how would you "edit" when in single mode? We would
have to introduce a lot of code just for this case as you cannot simply add
a box before the i and where are you supposed to press '{' in that case?

No, an argument would be a single inset , which can be either a
single token (character, anything that make sense) or a `box inset'. A
`box inset' is an inset which contains a string of math insets.

Andre> How should editing work when you want to change a_i to a_{ij}?

Using your award-winning (and patent pending) method of selecting the
'i' and using math-box-insert, which would create a box with i in it.

Note that I am not sure that this is better in all respects (and
unfortunately one has to implement it to find out), but it looks
interesting to me. And it gets you much closer to what TeX does.

How would you do that in latex? First you add {} around the single

center woes

[Andre Poenitz]

reLyX translates

   \begin{figure}[h]
   \begin{center}
   \includegraphics[height=0.8172in, width=2.9084in]{Weg3.eps}%
   \caption{Nonisomorphic trees with four vertices}%
   \end{center}
   \end{figure}

to something like

  \begin_float fig 
  \layout Standard
  \align center 
  \latex latex 
  \backslash includegraphics[height=0.8172in, width=2.9084in]{Weg3.eps}
  \latex default 

  \layout Caption
  \align center 
  Nonisomorphic trees with four vertices

  \layout Standard
  \end_float 

The problem is the '\align center' in the caption that gets read in
and displayed properly by LyX but is written to LaTeX as  

  \caption{\begin{center} ... \end{center}}

(and of course LaTeX chokes on that)

I seem unable to create such a situation from within LyX proper, but this
seriously hampers co-operation with users of Scientific Workplace, since
that's what they produce...

Indeed. But I can't see doing it easyly and consistently.

What about \frac? Do I need to have four insets for this then?

  \frac12
  \frac{11}2
  \frac1{22}
  \frac{11}{22}

The saved ' ' key press durcing input does not really seem worth the

No. Let me rephrase it: a macro argument is a math inset. A math inset
can be any normal inset (for example a single character or a\frac, as
in %a_\frac{a}{b}$, which latex understands perfectly), but it can be
a 'box inset', which holds a string of insets and outputs them enclosed
in braces.

I think it is actually simpler, since a macro does not need to know
what are their arguments: they are just single insets.

Ok. Currently we have a 'MathArray' which basically is your 'box inset'
and can hold any number of 'MathAtoms' (which are a sort of smart pointers
to other insets)

You suggest using instead some polymorphic structure that can be either of
a 'MathArray' as we have now, and a single 'MathAtom'.

Is that what you mean?

Guess what. We already have MathBraceInset, which are MathNestInsets with a
single cell (MathArray) that get written to LaTeX as '{', contents, '}'.

So we could reformulate this as:

Currently:

 MathFracInset == MathNestInset with two MathArrays
 MathArray == vector
 MathAtom  == smartpointer

Is this what you want:

 MathFracInset  == MathNestInset with two MathAtoms
 MathAtom   == smartpointer
 MathBraceInset == some special Mathinset == vector

?

This would look feasible. And it would actually memory usage a bit since a
MathAtom is smaller than a MathArray with one entry...

Why a short description ? Use the one above (suitable edited). This is
really really obscure code, and there is far too much of it that's

The problem first is to know whether it is desirable :) I cannot guess

Dekel,

I have modified the line as follows:

[...]
Style Author_Email
  PassThru  1
  CopyStyle Affiliation
  LatexName email
  LabelString   "Electronic Address: "

  TextFont
Family  Typewriter
  EndFont
  LabelFont
# override Typewriter
Family  Roman
  EndFont
End

Style Author_URL
  PassThru  1
  CopyStyle "Author Email"
  LatexName homepage
  LabelString   "URL: "
End
[...]

To no avail :(.

I still get the litteral text "\textasciitilde{}" in my final output.
I also tried with "Typewriter" replaced by "Roman", but also that
did not help.

Any other ideas?

Thanks,
Rob.

Well... it's a fairly fundamental blow to the current architecture.

Getting it compiled should be easy, however. The real problem will be to
get editing and navigation working again, and quite a few people won't
like it because it will be different...

Put the PassThru after the CopyStyle command.

Jug,

I can fix the cursor placement by commenting out line 570 in insetert.C 
(InsetERT::draw):

if (!isOpen()) {
draw_collapsed(pain, baseline, x);
// x += TEXT_TO_INSET_OFFSET;  <-- this one!
return;
}

But don't ask me why I did this ;-)

Agreed. I just had to share this bright idea with bright people :)

Don't you use subscripts?

Well I would say "good spoted" x is already set in draw_collapsed to the
width of the button + 2 * TEXT_TO_INSET_OFFSET and this has been fixed in
InsetCollpsable, but has been forgotten (probably myself) to fix it here too!

Will comit soon!

Give insets a full Row

[Juergen Vigna]

The attached small patch changes LyX's behaviour for NeedFullRow insets in
that it does give them ALWAYS the full row for drawing and does not care if
there is some indent or depth. IMO this is correct and should be done, also
this fixes a few problems we have and makes things easier to handle.

Comments!?

I've done so. Needless to say I tweaked it a little. I decided that the

Anyway, it's just the remnants of the BadWindow xforms bug, it looks
like.

It can be ignored. We shouldn't quieten it though, it is there to remind
us that this is an error condition

Graphics: file loading problems

[R. Lahaye]

Hi,

I have attached a tar file that contains an example lyx-file
and a graphics file, that hopefully demonstrate the problem.

Please start LyX-CVS from beginning (don't use an already
running LyX) and open the attached GraphicsTest.lyx, which
has "figures/MyGraph.jpg" as a graphics-float inset.

All you need to do is: View->DVI, which will generate an error.

See the attached png files for my LyX-canvas and the LaTeX-Error
window.
(sorry for all attachments, don't know howelse to show this).

Can you reproduce this error?
If so, please notice that in the process LyX generates a file 
"figures/MyGraph.eps". This shouldn't happen, should it?

But since we now have that eps file there, please open next
the graphics dialog and change the filename to the eps file.
All of a sudden View->DVI works fine!

There is something wrong here with non-(e)ps files.

Am I the only one experiencing this?

Regards,
Rob.
