What is the combination you are referring to?  As online display of books and 
other documents becomes increasingly common, the semantically meaningful use of 
color (e.g., syntax coloring program source code, color-coded navigational aids) 
becomes increasingly important.  As such, good support for color is one of the 
features of LyX I'm interested in.

Re: Initial Newbie Questions

[rgheck]

I just downloaded and installed LyX via the Windows installer. I've 
used LaTeX before (not recently), but never LyX. In playing around 
with the LyX Tutorial, I find that after changing some text to red or 
green and then generating DVI, I get errors such as this,

   LaTeX Error: Undefined color `RED'
 with this explanation when I click on the message (yes, the 
explanation really does refer to green, not red, notwithstanding the 
message above):

   \chapter
 {\textcolor{green}{Getting started with \LyX{}}}
   You're in trouble here.  Try typing   The resulting DVI has the appropriate colors on the appropriate text, 
so I don't

 know what the LaTeX errors are complaining about.


This is a weird problem. It's got something to do---I don't know what, 
yet---with the way LyX is handling "LyX" and "LaTeX". These get 
converted to custom macros, and they are not playing nice for some 
reason with \textcolor. I'm cc'ing this to the devel list so someone 
will take care of it, or at least explain it.


Furthermore, I find that I have to wait at least 10 seconds for Yap to 
update
its display after generating new DVI, and this is on what should be a 
pretty
fast machine:  a dual-core newish Thinkpad with 2GB of RAM.  Sometimes 
I've had to wait over 30 seconds for Yap to update.


You don't say which documents you are compiling. Even on my spankin' new 
quad core monster, the Extended Features manual can take a while to 
compile. This is a LaTeX thing. Given the references, figures, and 
stuff, there's a lot to do. LaTeX runs three times, at least. (If you 
launch LyX from a terminal, you can see what's going on.) If you were 
really going to write something as long as that manual, it'd be a good 
idea to break it up into chunks. I suppose that one's not broken up 
because it's intended to be readable online, via the Help menu. Anyway, 
it depends on what you are doing. And I guess it depends upon Yap. Maybe 
it's slow as dirt? What do other people use around here? Anyone? (I'm on 
Linux.)


It'd be nice if compiling happened in the background. I know that's on 
several people's radar, but no-one has gotten to it.

In 1.5.1 and 1.5.2, a system layout file is used whenever possible so
your local layout file is completely ignored. In 1.5.3, a local layout
file is used before the system one. This makes it easy for a user to
modify and use a local layout file, or distribute a document with an
updated layout file. The source of the bug, as I have explained, is
that the same layout file is loaded repeatedly by child documents.

The bundle feature is under active development, and it would be
another half a year (?) for 1.6.0 to be released with this feature.

The development on the XML side, as far as I can tell, is stalled, and
there is little hope to deliver it for 1.6.0. This feature is supposed
to be transparent to users though.

Re: 1.5.3 bug? - using child documents with same class causing error

Hey Bo,
I renamed the local file and did a reconfigure and that seems to have worked
- it also seems to have corrected the "0"s issue. I'm working on both
windows and mac (currently my mac), so I can't test the dev version till
next week but will let you know. I should also note that I've been using
these files with 1.5.2, 1.5.1, etc so I was surprised to see the issue but
thanks for helping out. I would've never figured that out. Really glad to
hear about the bundles support coming, I'm currently storing my figures in a
subfolder so that at least all the paths are relative to the document which
helps alot.

I'm also curious - i have also heard that there is going to be a new file
format that is XML-based. Is this going to be implemented for 1.6? Does this
have ramifications for lyx being for other purposes besides just LaTeX? for
example see my thread on docbook support.

Thanks,
Ryan

This happens because you put an eqnarray in a tabular cell, and this is
a catch-22 problem for LaTeX. Indeed, LaTeX tries to figure out the width
of the eqnarray, but the eqnarray can't be typeset because it has to extend
to the full width, which is what has to be determined...

There are two solutions here. The first one is specifying a width for
the column where you put the eqnarray. However, this is not convenient
because you have to perform some visual formatting.

The second, more convenient, one is using the aligned environment in
place of eqnarray. Create a math inset by Ctrl-M, put the cursor inside
it and then use the menu Insert->Math->Aligned Environment. You can get
more rows by hitting Ctrl-Enter. Now simply copy the content of the
eqnarray environment to the newly created aligned environment. Copy what
you have in the first eqnarray column to the first column of the aligned
environment and merge the second and third eqnarray columns into the
second column of the aligned environment. That's it.

However, this way the original definition is not retained.
This is equally simple and retains the definition:

Let me first assume it's the latter.

Since you are new to LyX and LaTeX: LaTeX isn't really designed to make

quotation font was chosen by the designers of the koma-book class, and

to be sure. But there's no way to do it from within LyX itself, because

find it in scrguide.pdf, which ought to have come with your TeX 
distribution. If not, you can find it on ctan.org. Direct LaTeX changes 
are entered into the document preamble, under Document>Settings. If you 
wanted the title to be Huge for example, you could add this to the preamble:

   \addtokomafont{title}{\Huge}
See section 3.2.1 of the manual for this. But this doesn't work for 
quotations.


If koma-book doesn't provide a way to change this, then you have to get

\renewenvironment{quotation}
  {\list{}{\listparindent 1em%
   \itemindent\listparindent

   \item\small\relax}
  {\endlist}
\renewenvironment{quote}
  {\list{}{\rightmargin\leftmargin}%

I think that'll work. I just stole it from the scrbook.cls class file, 
and added the "\small".


OK, so second: If you want to change the font size on-screen, then you 
need to modify the layout file. Copy scrbook.layout to your local LyX 
directory ($HOME/.lyx, on Linux), and then add these two lines to the 
end of it:

Style Quote
   Font

Style Quotation

Nice work.

Some of the problem(s) with the \cvline specification in this class file
have been noted in the Bug (at least in part):

http://bugzilla.lyx.org/show_bug.cgi?id=4415

Xavier, the maintainer of moderncv, is aware of some of these things. I'd
suggest that you flip him a condensed version of these two points and let

No, they can also be added in the other tabs, though the procedure is
less evident. If you choose 'Options -> Customize entry types', you can
choose an entry type on the left (e.g. 'article'). On the right side the
required and optional fields appear. There you can choose from the
dropdown list or give a field that is not selectable from the dropdown
list (in your case 'language'). Clicking on 'Add' appends the field name
to the list. Afterwards you can move it around using the arrow keys.

Note that it is also possible to add entry types that not yet exist
(e.g. 'myarticle') by typing it into the input field at the bottom left
corner and clicking on 'Add'.

I didn't get that bit, sorry. Do you mean adding a value to the new
field?

> How can I make this the default setting for all my bib files?

'Options -> Preferences' and then the buttons 'Import preferences' and
'Export preferences' in the bottom left corner.

If you have suggestions on how to improve the documentation, please give
feedback to me via private mail, also in German if you like

math mode latex errors

[Hicham Mouline]

Hello,
Being a beginner of lyx (no knowledge of latex), I have this lyx-generated 
latex source (lyxout.txt attached)
When doing view / PDF (PDFLatex), latex run 1, I get a few "Missing ... 
inserted"
and these errors:

>LaTeX Error: \begin{tabular} on input line 90 ended by \end{eqnarray*}.

... & = & d_{1}-\sigma\sqrt{T}\end{eqnarray*}

Your command was ignored.

Type I   to replace it with another command,

or  to continue without it.

>Too many }'s.

\end{tabular}

\begin{tabular}{|c|c|c||c|}

You've closed more groups than you opened.

Such booboos are generally harmless, so keep going.

No pdf is generated. The lyx doc contains tables, and a lot of math formulae.

Any ideas?

The standard Black-Scholes framework is extended to cope with time-dependency
of the risk-free rate, dividend and volatility parameters.

In the following,

\begin{lyxlist}{00.00.}
\item [{$V$}] is the value of the option being priced,
\item [{$c$}] the price of a European call
\item [{$p$}] the price of a European put
\item [{$X$}] the option's strike
\item [{$T$}] the option's time to expiration date
\item [{$S$}] the price of the contract underlying the option
\item [{$\sigma$}] the standard deviation of the continuously compounded
log returns, per sqrt of annum, can be constant or time-dependent
$\sigma(t)$
\item [{$D$}] the present value of the dividends during the life of the
option, discounted at the risk-free rate, in case the underlying contract
pays discrete dividends
\item [{$q$}] the continuously compounded dividend yield, can be constant
or time-dependent $q(t)$
\item [{$r$}] the continuously compounded risk-free rate, can be constant
or time-dependent $r(t)$
\item [{$N(.)$}] the cumulative standard normal distribution function
\item [{$n(.)$}] the standard normal distribution density function

$V$ value of the option

\[
\frac{\partial V}{\partial 
t}+\frac{1}{2}\sigma^{2}S^{2}\frac{\partial^{2}V}{\partial

Questions about graphics

[Deskins, Nathaniel A]

 
I'm relatively new to Latex and Lyx. I have a few questions about
images/graphics.

1) How does Lyx/Latex treat graphic resizing? For instance, I have a
900x900 pixel image. If I manually set the image to be 3 inches wide,
does Lyx simply rescale it to be a 3 inch by 3 inch image with 300 dpi? 

Or does it assume some dpi and use some algorithm to rescale the pixel
size (i.e. 1200x1200 pixels)?


2) What image format is recommended? I understand Lyx can convert files
on the fly, but is there a 'best practices' approach to this? Or should
I not worry about this? 

3) I've created several figure floats and put two figures in each of
them with the images right on top of each other within the float. All
look fine, but one float puts the figure caption right through the
second image. What would cause this and how do I fix it?

Thank you,

Aaron

Neal,

1. The first time the footnote occurs, put it in normally. 

2. Then put a label in the footnote.

3. To refer to the same footnote a second time, insert a crossreference to the 
label and format it as superscript.

4. Example attached.

RE: (latex question) Repeated footnote?

[Daniel CLEMENT]

Also possible :

Place the cross-reference to the labeled footnote in a superscript, so that
it will appear as a note too.

Thus you get twice the same reference to the same footnote, they look alike,
and the numbering si preserved.

Re: 1.5.3 bug? - using child documents with same class causing error

It is a new feature, and you have encountered a bug that I think I
have fixed. (I would appreciate it if you can see if the problem
persists with
the latest development version such as
http://www.lyx.org/~bpeng/LyX-1.5.4svn-2008-01-04-Installer.exe ).

Begin with lyx 1.5.0, local, meaning in the same directory with the
document, style file (.sty, .cls) and layout (.layout) file can be
used directly by a document. You can not create such a document in lyx
(unless you modify a .lyx file directly) because local .layout does
not show up in the style list, but if you send your document, along
with your layout and .cls file to your co-authors, they do not have to
install anything to open and modify your file. This feature is not
well-publicized because it is a precursor to a 'bundle' feature (due
1.6.0) with which you can bundle figures, layouts, bibtex etc to a
single .lyx file.

Your problem is caused by the repeated loading of the same local
layout file by your child documents, which is a bug that I should have
fixed.

> Is there a preference for which to remove? Also, will I need to do a

You can use the latest svn if it fixes your problem, or remove local
layout file. Removing system layout file may not work.

> And, just for good measure, any comment on why the "0"s are appearing? is
> this related to the same issue?

I am not sure about this one. If the problem persists after the layout
problem is fixed, you can send a shrinked version of your document to
me, or the lyx-users list.

Bo

You could do something like

1: [label-in-footnote] This is a footnote.
2: On this topic, see footnote [reference:label-in-footnote]

That's what labels in footnotes could e.g. be used for.

language field in JabRef

[Wolfgang Engelmann]

in order to use babelbib for handling references of different languages 
correctly I am supposed to create a field 
language 
in Jabref. How do I do it and how can I insert 
english in each reference?
Most of my references are in english, than I need only to change the remaining 
one into ngerman, french etc. 
Of course, it would be ideal to have a program which determines the language 
automatically and puts it in the language field. But that is probably asked 
for too much.

This needs to be replaced with a command string for an PDF->EPS converter

Exactly. Reading the Help>Customization guide will help with the format
(basically, $$i will be replace with input-filename and $$o with output
filename).

Also, after making sure that the from: and to: formats are still set as
intended, you need to press the add button (left top corner) and than [Save].



Regarding a suitable command, we need to know your system a bit more...

pdftops - Portable Document Format (PDF) to PostScript converter


SYNOPSIS

   pdftops [options] [PDF-file [PS-file]]


   -f number
  Specifies the first page to print.

   -l number
  Specifies the last page to print.
  
   -eps   Generate an Encapsulated PostScript (EPS)  file.   An  EPS  file
  contains a single image, so if you use this option with a multi-
  page PDF file, you must use -f and -l to specify a single  page.
  No more than one of the mode options (-eps, -form) may be given.

Beamer style

[sticken]

Hi,

i am using LyX 1.5 on Windows XP/Mac OS X. I tried using the Beamer Layout
style (latex-beamer). I got it working, but run into several caveats:

- When I used a shorttitle and copied text into the field, it did not work. I
had to enter the text manually.
- I figured out it is important to nest styles. A list is nested in a block is
nested in a frame...
- I had problems to to use consecutive Block styles. I solved it by using a
empty paragraph in between with a LyX note.
- I worked out there must be a FrameEnd at the end of the document.
- I could not compile the beamer example in the examples folder. I had to
change the document font styles to default values and remove an ert (pgf
graphic). Then it worked.

bye,

However, it is controled by the ui files. You can e.g. copy stdmenus.inc
(/usr/share/lyx/ui/stdmenus.inc on my Debian system) to your personal lyx
dir (~/.lyx/ui/stdmenus.inc, say) and modify e.g.

-   Submenu "File|F" "file"
+   Submenu "File" "file"


Some of the Alt- bindings (the visible ones) are realised via
the stdmenus file, while others (invisible ones) are added via menus.bind
(or e.g. /de/menus.bind) So you might have to add bindings disabled in
stdmenus.inc to menus.bind.

I did not find out, how the translation of the ui bindings work - if I
e.g. change

-   Item "Revert to Saved|R" "buffer-reload"
+   Item "Reload from Disk|R" "buffer-reload"

the changed menu entry appears in English also in a German LyX interface.
