 Of course transform semantic markup to semantic markup.  This implies
 that the website uses really good markup (text with HTML markup
 indicating its logical structure), not CSS-styleddiv  andspan  soups.


 The difficulty is that HTML is very limited in what it is capable of 
 marking, for the simple reason that there aren't very many tags. 

This is why our task becomes easy, if we decide to support HTML markup
only. 

Such a HTML importer would stand in the middle between simple text import
(no structure/markup preserved) and the annoying fully-formatted
pasting of some WPs. The basic structure of the document (lists,
sections, emphasized and preformatted text) is preserved in a WYSIWYG
way.

 LyX character styles, for example, would almost uniformly correspond to
 span, except for the handful of obvious exceptions. That, it seems to
 me, is why use div and span for everything has become almost the
 norm.  See e.g. elyxer's HTML output. LyX's is more flexible, because
 it is specifiable in the layout. But the problem remains.

Similar to the goal to achieve a loss-less lyx-latex-lyx round-trip,
we could (as a further option) extend the HTML importer to provide for
the features/constructs of the native HTML export.

Floating and Space between paragraph

Re: Floating and Space between paragraph

Nothing really. This is LaTeX doing it's job. When there is extra
space on a page, LaTeX expands the space between paragraphs to fill
it. Maybe having more paragraphs or smaller tables/images also help.

Assure that you _don't_ have set the float placement option here 
definitively, neither in the document settings and also not in the 
settings of the table floats.


If this is already the case, can you please send a _small_ LyX example

This can occur when you have large floats, images or tables that don't 
fit on the current page. To avoid that, try to use always figure/table 
floats and not plain figures/tables. Also assure that the float 
placement option is _not_ here definitively.


If this still doesn't help, insert a page break before the 
float/image/table, or whatever is too large to fit on the page.


If you even then still don't succeed, you can send me a LyX example file.

Re: silly newby graphics question

[Helge Hafting]

Richard Brown wrote:

This is a sily question, but my only excuse is I'm trying to understand.
Thanks for your patience, understanding and answers!

Up to now I've been inserting my photographs and other graphics in a float.
But what is the float actually  for? Can I just insert the graphics files
directly via the Insert  Graphics command? If I can, what are the
advantages and disadvantages of each system, that is with or without  a
float?


You can insert graphics directly without a float.
This has one disadvantage, which is the reason why
floats were invented:

You have probably noticed that text isn't broken into pages in LyX. That 
happens later, when you print (or make a PDF). The problem is - what 
happens when there is a rather big image, but it doesn't quite fit?


For example, half the page is full of text, but now there is an image
that need 2/3 of a page. There isn't room for it, so this page ends and 
the next page begins with the big image on top.


And the problem is that the previous page is now only half full. This 
wastes paper, and it looks ugly and unprofessional.


Of course, you can place the big image carefully to avoid this. (Using a 
pdf preview, and moving the image around.)
Now, consider a book manuscript with 50 such big images. Then you need 
to add half a page of text in the beginning - everything moves, and just 
about every image needs to be fixed again.


An automatic solution was needed - floats. With the image in a float, 
this happens during page layout:

* If the floating image fits, it goes right there.
* If it doesn't fit, it still moves to the next page. But the current
  page does *not* end. It is filled up with whatever text that comes
  after the big image. So, no half-full pages any more.
* The price for this is that the floats not necessarily appear exactly
  where you want them to be. (When they won't fit.)

As others have pointed out, floats also offers some niceties like cross
referencing and list of floats. But the automatic and nice-looking 
page breaking in the precence of (big) images is the main thing.

Re: inserting black and white graphics (musical notation) from TIFF

[Helge Hafting]

Richard Brown wrote:

I have some TIFF files exported from Sibelius, the music scoring program.
They are just high-quality images of black and white music scores. I tried
converting them to jpg in GIMP for inclusion in my Lyx manuscript, but the
results were awful- or at least, they were awful in lyx. When I open the
converted jpg files in other software they are really clear and good, but in
Lyx onscreen they are very poor and in the dvi files even worse. Many of the
fine lines that indicate musical notes are patchy, and a lot have
disappeared. Has anyone got any good ideas as to how to process this?


First, don't convert to jpg. You can insert tiff files directly in LyX.

While jpg is useful for photos, it is totally useless for anything with 
 a low number of colors and sharp contrasts. (Screen dumps, line art, 
and of course black  white music.)


As others have pointed out, using a vector graphic format like PDF (or 
postcript) is even better.  The reason: a bitmap image (tiff,png,jpg) 
has limited resolution. Therefore, it cannot look good on a device with 
higher resolution. Most bitmap images are made to look good on screen, a 
quality image looks good even on a really big screen. But that isn't 
enough for printing. Even a low-end printer has *much* higher resolution 
than the best screens, so bitmap images never gets really good in print. 
(Or in dvi, which really is a print preview.)


Vector graphics is completely different. Such files are independent of 
resolution. So they work perfectly on any printing device. There is one 
exception, and that is when one converts a bitmap into a pdf. The bitmap 
doesn't become vector graphics that way.


The only way is to use Sibelius, and get vector graphics from there. 
Perhaps it has options like export or save as, where you can specify 
a format like pdf or postscript (ps) or encapsulated postscript?


I haven't tried Sibelius, so I don't know. I have test-printed some 
music using lilypond though, and have gotten nice results that way.

2. sentence autocapitalization

Word has botched this completely - and it degrades the correspondence I

3. grammar check (not crucial)

Doable - do you know an open-source grammar checker we could use? LyX 
already use external programs for spellchecking. . .



4. search highlight occurences

For the incremental search, I guess?


6. edit history (go back to last edits). We seem to have only one step back?
Not sure what you mean here. You can undo much more than one step. All 
the way back to the state when the file was loaded into LyX, I believe.



7. the rest of the world operates on rich text/html. LyX doesn't (clipboard
integration is poor, copy-pasting from/to web loses formatting)


LyX does not use rich text internally. It uses a very different 
format. I don't think a perfect converter can be made. Still, it might 
be possible to make a decent converter for common cases. If someone is 
interested in doing it, that is.




8. 'pasted from' and url for every paste from the web (onenote uses this and
it's damn inspired)


Might be useful. Can this information be fetched from the clipboard? Or 
how would LyX get this data? Inserting a note or comment with the URL 
wouldn't be hard to code, but how to get it in the first place?

It's hard Julio. It's hard enough that I couldn't even *specify* a layout 
editor, though I tried. If I'd been able to specify one, I'd have either 
pestered the LyX crew to write it, or written it myself in Perl/Tk (I'm not 
much of a Qt type of guy).




The customization manual already tells how to write a layout file.  One 
can specify a GUI for doing the same, removing much of the tediousness

and many possibilities for error. (For example, such a GUI would always
remember to put End somewhere after Style stylename.

This would give us an easy way of making layout files. The problem is, 
to do anything interesting with it, one would still need to know latex. 
 Instead of writing a .layout from scratch, you could fill out a form 
like this (the layoutmodule code from logical markup):


=
Type: charstyle  (alt. paragraph style, document class)
Name of your character style: Code

Font in LyX:
 Family: typewriter
 Size: unchanged
 weight: unchanged
 ...

Latex implementation: command  (alt. environment)
Latex command: code
Latex preamble: \newcommand{\code}[1]{\texttt{#1}}
=

Of course, many of the fields would be comboboxes, making it impossible 
to enter a wrong value.


The tricky parts would be the latex command or the preamble. Still, it 
might be useful for those who understands some latex.



Making a layout editor for people who don't understand latex is much 
harder. And to some extent pointless. If the layout editor understand 
more latex than lyx does, then perhaps the effort could be better spent 
on improving lyx instead. And if it understands less, then it doesn't 
implement all that LyX can do.


Still, one could perhaps have something like math macros, but for 
text. Let the user create a style by doing ordinary edits on a demo 
word. This way, a user could create a style for, say, big green boxed 
marginal notes by inserting a marginal note around the demo text, then 
a box, and then use the text style dialog to make the text big and green 
as well.


I'm thinking the best way to address the difficulty of new environments and 
character styles might be to start a public collection of them. A person could 
start with something close to what he wants and tweak it til it's right. Such 
a collection could come with a supporting document that organizes various 
environments and character styles in a hierarchy so that what you need is 
easily findable.




Yes, this can make LyX more and more useful. There will still be people
complaining that I can't make my own style in an easy way though. :-/

Consider allowing the floats onto page of floats only. That way, there

Mac OSX Lyx: No XDVI?

Hi everyone

After years of using Linux, I was persuaded by my daughter to try her
hand-down Mac.
I installed all my usual goodies - C development system and, of course, LyX.

The LyX works fine, after I had got used to the Mac idiom of separate
windows for LyX and each opened document.
But ..
When I click on the View DVI button, LyX behaves as though I had hit the
View PDF document.
Is this expected behaviour?
Or do I have to find and install the OSX version of Xdvi?

 indicating its logical structure), not CSS-styleddiv  andspan  soups.


 The difficulty is that HTML is very limited in what it is capable of 
 marking, for the simple reason that there aren't very many tags. 

This is why our task becomes easy, if we decide to support HTML markup
only. 

Such a HTML importer would stand in the middle between simple text import
(no structure/markup preserved) and the annoying fully-formatted
pasting of some WPs. The basic structure of the document (lists,
sections, emphasized and preformatted text) is preserved in a WYSIWYG
way.

 LyX character styles, for example, would almost uniformly correspond to
 span, except for the handful of obvious exceptions. That, it seems to
 me, is why use div and span for everything has become almost the
 norm.  See e.g. elyxer's HTML output. LyX's is more flexible, because
 it is specifiable in the layout. But the problem remains.

Similar to the goal to achieve a loss-less lyx-latex-lyx round-trip,
we could (as a further option) extend the HTML importer to provide for
the features/constructs of the native HTML export.

Floating and Space between paragraph

Nothing really. This is LaTeX doing it's job. When there is extra

it. Maybe having more paragraphs or smaller tables/images also help.

Assure that you _don't_ have set the float placement option here 
definitively, neither in the document settings and also not in the 
settings of the table floats.


If this is already the case, can you please send a _small_ LyX example

This can occur when you have large floats, images or tables that don't 
fit on the current page. To avoid that, try to use always figure/table 
floats and not plain figures/tables. Also assure that the float 
placement option is _not_ here definitively.


If this still doesn't help, insert a page break before the 
float/image/table, or whatever is too large to fit on the page.


If you even then still don't succeed, you can send me a LyX example file.

Re: silly newby graphics question

[Helge Hafting]

Richard Brown wrote:

This is a sily question, but my only excuse is I'm trying to understand.
Thanks for your patience, understanding and answers!

Up to now I've been inserting my photographs and other graphics in a float.
But what is the float actually  for? Can I just insert the graphics files
directly via the Insert  Graphics command? If I can, what are the
advantages and disadvantages of each system, that is with or without  a
float?


You can insert graphics directly without a float.
This has one disadvantage, which is the reason why
floats were invented:

You have probably noticed that text isn't broken into pages in LyX. That 
happens later, when you print (or make a PDF). The problem is - what 
happens when there is a rather big image, but it doesn't quite fit?


For example, half the page is full of text, but now there is an image
that need 2/3 of a page. There isn't room for it, so this page ends and 
the next page begins with the big image on top.


And the problem is that the previous page is now only half full. This 
wastes paper, and it looks ugly and unprofessional.


Of course, you can place the big image carefully to avoid this. (Using a 
pdf preview, and moving the image around.)
Now, consider a book manuscript with 50 such big images. Then you need 
to add half a page of text in the beginning - everything moves, and just 
about every image needs to be fixed again.


An automatic solution was needed - floats. With the image in a float, 
this happens during page layout:

* If the floating image fits, it goes right there.
* If it doesn't fit, it still moves to the next page. But the current
  page does *not* end. It is filled up with whatever text that comes
  after the big image. So, no half-full pages any more.
* The price for this is that the floats not necessarily appear exactly
  where you want them to be. (When they won't fit.)

As others have pointed out, floats also offers some niceties like cross
referencing and list of floats. But the automatic and nice-looking 
page breaking in the precence of (big) images is the main thing.

Re: inserting black and white graphics (musical notation) from TIFF

[Helge Hafting]

Richard Brown wrote:

I have some TIFF files exported from Sibelius, the music scoring program.
They are just high-quality images of black and white music scores. I tried
converting them to jpg in GIMP for inclusion in my Lyx manuscript, but the
results were awful- or at least, they were awful in lyx. When I open the
converted jpg files in other software they are really clear and good, but in
Lyx onscreen they are very poor and in the dvi files even worse. Many of the
fine lines that indicate musical notes are patchy, and a lot have
disappeared. Has anyone got any good ideas as to how to process this?


First, don't convert to jpg. You can insert tiff files directly in LyX.

While jpg is useful for photos, it is totally useless for anything with 
 a low number of colors and sharp contrasts. (Screen dumps, line art, 
and of course black  white music.)


As others have pointed out, using a vector graphic format like PDF (or 
postcript) is even better.  The reason: a bitmap image (tiff,png,jpg) 
has limited resolution. Therefore, it cannot look good on a device with 
higher resolution. Most bitmap images are made to look good on screen, a 
quality image looks good even on a really big screen. But that isn't 
enough for printing. Even a low-end printer has *much* higher resolution 
than the best screens, so bitmap images never gets really good in print. 
(Or in dvi, which really is a print preview.)


Vector graphics is completely different. Such files are independent of 
resolution. So they work perfectly on any printing device. There is one 
exception, and that is when one converts a bitmap into a pdf. The bitmap 
doesn't become vector graphics that way.


The only way is to use Sibelius, and get vector graphics from there. 
Perhaps it has options like export or save as, where you can specify 
a format like pdf or postscript (ps) or encapsulated postscript?


I haven't tried Sibelius, so I don't know. I have test-printed some 
music using lilypond though, and have gotten nice results that way.

Not sure what you mean here. You can undo much more than one step. All

LyX does not use rich text internally. It uses a very different

be possible to make a decent converter for common cases. If someone is 
interested in doing it, that is.




8. 'pasted from' and url for every paste from the web (onenote uses this and
it's damn inspired)


Might be useful. Can this information be fetched from the clipboard? Or

It's hard Julio. It's hard enough that I couldn't even *specify* a layout

pestered the LyX crew to write it, or written it myself in Perl/Tk (I'm not 
much of a Qt type of guy).




The customization manual already tells how to write a layout file.  One 
can specify a GUI for doing the same, removing much of the tediousness

and many possibilities for error. (For example, such a GUI would always
remember to put End somewhere after Style stylename.

This would give us an easy way of making layout files. The problem is, 
to do anything interesting with it, one would still need to know latex. 
 Instead of writing a .layout from scratch, you could fill out a form 
like this (the layoutmodule code from logical markup):


=
Type: charstyle  (alt. paragraph style, document class)
Name of your character style: Code

Font in LyX:
 Family: typewriter
 Size: unchanged
 weight: unchanged
 ...

Latex implementation: command  (alt. environment)
Latex command: code
Latex preamble: \newcommand{\code}[1]{\texttt{#1}}
=

Of course, many of the fields would be comboboxes, making it impossible 
to enter a wrong value.


The tricky parts would be the latex command or the preamble. Still, it 
might be useful for those who understands some latex.



Making a layout editor for people who don't understand latex is much 
harder. And to some extent pointless. If the layout editor understand 
more latex than lyx does, then perhaps the effort could be better spent 
on improving lyx instead. And if it understands less, then it doesn't 
implement all that LyX can do.


Still, one could perhaps have something like math macros, but for 
text. Let the user create a style by doing ordinary edits on a demo 
word. This way, a user could create a style for, say, big green boxed 
marginal notes by inserting a marginal note around the demo text, then 
a box, and then use the text style dialog to make the text big and green 
as well.


I'm thinking the best way to address the difficulty of new environments and 
character styles might be to start a public collection of them. A person could 
start with something close to what he wants and tweak it til it's right. Such 
a collection could come with a supporting document that organizes various 
environments and character styles in a hierarchy so that what you need is 
easily findable.




Yes, this can make LyX more and more useful. There will still be people
complaining that I can't make my own style in an easy way though. :-/

Consider allowing the floats onto page of floats only. That way, there

Mac OSX Lyx: No XDVI?

After years of using Linux, I was persuaded by my daughter to try her
hand-down Mac.
I installed all my usual goodies - C development system and, of course, LyX.

The LyX works fine, after I had got used to the Mac idiom of separate
windows for LyX and each opened document.
But ..
When I click on the View DVI button, LyX behaves as though I had hit the
View PDF document.
Is this expected behaviour?
Or do I have to find and install the OSX version of Xdvi?

Because CTAN contains the *LaTeX* packages/classes while for using
them in LyX, we need *in addition to them* also LyX modules/layouts.

This need for definitions on both, LyX and LaTeX levels is a main
reason why creating/editing LyX layouts is such a complex task.
(And also the base for much frustation for people with either a just a
LyX layout or just a LaTeX class or package.)

No, rather an alternative (a paragraph on a related page instead of a
full wiki page). You might consider adding inter-wiki links at the
appropriate places (sparingly to avoid the impression of spamming).

A generic error reporting for all programs called by LyX would be a great

For the "Unicode in bibtex database problem", the solution might be to
use a unicode aware processor, e.g.

   * Database in BibTeX, BibTeXML and YAML formats.
   * full Unicode support.
   * Write to TeX, HTML and plain text.

I don't think this is very easy to do. Templates are just files, and
what shows them is just a file browser. We can't ask the file browser
not to show files that don't have associated LaTeX classes.
 

Then, we could consider grouping templates in sub-directories like e.g.

   templates/ # standard document classes
   templates/letter.lyx
   templates/slides.lyx
   ...
   templates/texlive  # document classes in texlive
   templates/texlive/dinbrief.lyx
   ...
   templates/other/   # "exotic" document classes

or in every template clearly state in a LyX-Note the required LaTeX
documentclass (and its home URL).

   
Exotic is in the eye of the beholder, I'm afraid, and what's standard 
varies from TeX distribution to TeX distribution. There's really no 
telling what someone might have installed. The issue here, or so it 
seems to me, is just a simple confusion about what LyX provides, how it 
relates to LaTeX, and what LaTeX provides. The fact that the dialog that 
pops up when you don't have the document class is so confusing doesn't 
help. But this, I believe, is now resolved in trunk.

Floating and Space between paragraph

[YURENA MENDOZA]

Hello,I have several tables floating in my document and they will be the
reason why along my document there are greater spaces between several
paragraphs despite I select the "default" option space between paragraphs.
What can I do in order to retain all paragraphs with the same length between
them?

Thanks

Re: Floating and Space between paragraph

[Julio Rojas]

Nothing really. This is LaTeX doing it's job. When there is extra
space on a page, LaTeX expands the space between paragraphs to fill
it. Maybe having more paragraphs or smaller tables/images also help.

Assure that you _don't_ have set the float placement option "here 
definitively", neither in the document settings and also not in the 
settings of the table floats.


If this is already the case, can you please send a _small_ LyX example 
file to be able to have a closer look?

This can occur when you have large floats, images or tables that don't 
fit on the current page. To avoid that, try to use always figure/table 
floats and not plain figures/tables. Also assure that the float 
placement option is _not_ "here definitively".


If this still doesn't help, insert a page break before the 
float/image/table, or whatever is too large to fit on the page.


If you even then still don't succeed, you can send me a LyX example file.

Re: silly newby graphics question

[Helge Hafting]

Richard Brown wrote:

This is a sily question, but my only excuse is I'm trying to understand.
Thanks for your patience, understanding and answers!

Up to now I've been inserting my photographs and other graphics in a float.
But what is the float actually  for? Can I just insert the graphics files
directly via the Insert > Graphics command? If I can, what are the
advantages and disadvantages of each system, that is with or without  a
float?


You can insert graphics directly without a float.
This has one disadvantage, which is the reason why
floats were invented:

You have probably noticed that text isn't broken into pages in LyX. That 
happens later, when you print (or make a PDF). The problem is - what 
happens when there is a rather big image, but it doesn't quite fit?


For example, half the page is full of text, but now there is an image
that need 2/3 of a page. There isn't room for it, so this page ends and 
the next page begins with the big image on top.


And the problem is that the previous page is now only half full. This 
wastes paper, and it looks ugly and unprofessional.


Of course, you can place the big image carefully to avoid this. (Using a 
pdf preview, and moving the image around.)
Now, consider a book manuscript with 50 such big images. Then you need 
to add half a page of text in the beginning - everything moves, and just 
about every image needs to be fixed again.


An automatic solution was needed - floats. With the image in a float, 
this happens during page layout:

* If the floating image fits, it goes right there.
* If it doesn't fit, it still moves to the next page. But the current
  page does *not* end. It is filled up with whatever text that comes
  after the big image. So, no half-full pages any more.
* The price for this is that the floats not necessarily appear exactly
  where you want them to be. (When they won't fit.)

As others have pointed out, floats also offers some niceties like cross
referencing and "list of floats". But the automatic and nice-looking 
page breaking in the precence of (big) images is the main thing.

Re: inserting black and white graphics (musical notation) from TIFF

[Helge Hafting]

Richard Brown wrote:

I have some TIFF files exported from Sibelius, the music scoring program.
They are just high-quality images of black and white music scores. I tried
converting them to jpg in GIMP for inclusion in my Lyx manuscript, but the
results were awful- or at least, they were awful in lyx. When I open the
converted jpg files in other software they are really clear and good, but in
Lyx onscreen they are very poor and in the dvi files even worse. Many of the
fine lines that indicate musical notes are patchy, and a lot have
disappeared. Has anyone got any good ideas as to how to process this?


First, don't convert to jpg. You can insert tiff files directly in LyX.

While jpg is useful for photos, it is totally useless for anything with 
 a low number of colors and sharp contrasts. (Screen dumps, line art, 
and of course black & white music.)


As others have pointed out, using a vector graphic format like PDF (or 
postcript) is even better.  The reason: a bitmap image (tiff,png,jpg) 
has limited resolution. Therefore, it cannot look good on a device with 
higher resolution. Most bitmap images are made to look good on screen, a 
quality image looks good even on a really big screen. But that isn't 
enough for printing. Even a low-end printer has *much* higher resolution 
than the best screens, so bitmap images never gets really good in print. 
(Or in dvi, which really is a print preview.)


Vector graphics is completely different. Such files are independent of 
resolution. So they work perfectly on any printing device. There is one 
exception, and that is when one converts a bitmap into a pdf. The bitmap 
doesn't become vector graphics that way.


The only way is to use Sibelius, and get vector graphics from there. 
Perhaps it has options like "export" or "save as", where you can specify 
a format like pdf or postscript (ps) or encapsulated postscript?


I haven't tried Sibelius, so I don't know. I have test-printed some 
music using lilypond though, and have gotten nice results that way.

Hi all,

In no special order, things that I miss in lyx...

1. incremental search

That'd be nice, sure.


2. sentence autocapitalization


Can you specify a way to do this *correctly*, without having the 
computer make lots of mistakes?


Word has botched this completely - and it degrades the correspondence I 
get. (I know how to turn such things off, most people doesn't even know 
that it can be turned off.) I get letters where the word "I" is 
capitalized, which is wrong when the language isn't english, for example.



3. grammar check (not crucial)

Doable - do you know an open-source grammar checker we could use? LyX 
already use external programs for spellchecking. . .



4. search highlight occurences

For the incremental search, I guess?


6. edit history (go back to last edits). We seem to have only one step back?
Not sure what you mean here. You can "undo" much more than one step. All 
the way back to the state when the file was loaded into LyX, I believe.



7. the rest of the world operates on rich text/html. LyX doesn't (clipboard
integration is poor, copy-pasting from/to web loses formatting)


LyX does not use "rich text" internally. It uses a very different 
format. I don't think a perfect converter can be made. Still, it might 
be possible to make a decent converter for common cases. If someone is 
interested in doing it, that is.




8. 'pasted from' and url for every paste from the web (onenote uses this and
it's damn inspired)


Might be useful. Can this information be fetched from the clipboard? Or 
how would LyX get this data? Inserting a note or comment with the URL 
wouldn't be hard to code, but how to get it in the first place?

It's hard Julio. It's hard enough that I couldn't even *specify* a layout 
editor, though I tried. If I'd been able to specify one, I'd have either 
pestered the LyX crew to write it, or written it myself in Perl/Tk (I'm not 
much of a Qt type of guy).




The customization manual already tells how to write a layout file.  One 
can specify a GUI for doing the same, removing much of the tediousness

and many possibilities for error. (For example, such a GUI would always
remember to put "End" somewhere after "Style stylename".

This would give us an "easy" way of making layout files. The problem is, 
to do anything interesting with it, one would still need to know latex. 
 Instead of writing a .layout from scratch, you could fill out a form 
like this (the layoutmodule "code" from logical markup):


=
Type: charstyle  (alt. paragraph style, document class)
Name of your character style: Code

Font in LyX:
 Family: typewriter
 Size: unchanged
 weight: unchanged
 ...

Latex implementation: command  (alt. environment)
Latex command: code
Latex preamble: \newcommand{\code}[1]{\texttt{#1}}
=

Of course, many of the fields would be comboboxes, making it impossible 
to enter a wrong value.


The tricky parts would be the latex command or the preamble. Still, it 
might be useful for those who understands some latex.



Making a layout editor for people who don't understand latex is much 
harder. And to some extent pointless. If the layout editor understand 
more latex than lyx does, then perhaps the effort could be better spent 
on improving lyx instead. And if it understands less, then it doesn't 
implement all that LyX can do.


Still, one could perhaps have something like "math macros", but for 
text. Let the user create a style by doing ordinary edits on a demo 
word. This way, a user could create a style for, say, "big green boxed 
marginal notes" by inserting a marginal note around the demo text, then 
a box, and then use the text style dialog to make the text big and green 
as well.


I'm thinking the best way to address the difficulty of new environments and 
character styles might be to start a public collection of them. A person could 
start with something close to what he wants and tweak it til it's right. Such 
a collection could come with a supporting document that organizes various 
environments and character styles in a hierarchy so that what you need is 
easily findable.




Yes, this can make LyX more and more useful. There will still be people
complaining that "I can't make my own style in an easy way" though. :-/

Consider allowing the floats onto "page of floats" only. That way, there 
will be no pages with mixed text and floats. And so the page breaking 
algorithm woon't need to compensate for objects of unusual size.

Mac OSX Lyx: No XDVI?

[john]

Hi everyone

After years of using Linux, I was persuaded by my daughter to try her
hand-down Mac.
I installed all my usual goodies - C development system and, of course, LyX.

The LyX works fine, after I had got used to the Mac idiom of separate
windows for LyX and each opened document.
But ..
When I click on the View DVI button, LyX behaves as though I had hit the
View PDF document.
Is this expected behaviour?
Or do I have to find and install the OSX version of Xdvi?
