making \citep the default natbib citation style?

[Justin Wood]

Hi all. The usual apologies for asking a dumb and/or tired question, but I
have hunted through the list archive and online in general to no avail.

[System: LyX 1.6.5 on Mac OS X 10.6.2]

I'm using natbib citation style, set to *author-year*, with a 3rd party
style file for Chicago
format.
This works perfectly. As is normal in Chicago -- unless mentioning the
author name(s) explicitly in the text -- I use the *parenthetical *citation
format of *(Jones, 2001)*, which is readily provided by natbib's
*\citep*command. So far so good.

However, when LyX initially inserts a citation from a *new* reference not
previously used, it defaults to the *textual *citation format: natbib's *
\citet* command. This is not what I need. I can of course change any such
citation to parenthetical (\citep), or any of the other options, quite
simply with the GUI, but I would dearly love to be able to specify which
citation format is the *default*. As a workaround I can redefine the \citet
command using something like: \renewcommand{\citet}{\citep}. That nicely
changes the citation style to parenthetical in any output file.

But there are two problems with that kludge. One, I can't then use \citet if
I genuinely want to in the same document for some reason. And two, it still
displays as textual in LyX itself -- which may or may not be a real issue,
depending on how pedantic you are (and I am).

So is there any way in the natbib configuration, in LyX itself, or with some
other LaTeX preamble, that I can change the default insert-citation to be
\citep?

Thanks! And big respect to the general LyX community for this excellent
tool.

PS - for the most part my citations are inserted via lyxpipe using this
tasty little plugin for Zotero :
LyZ

announce: template to write Ph.D. theses with LyX

[Uwe Stöhr]

Dear LyX users,

there was often the question on this LyX how to write a thesis with LyX. There are many templates 
available on the Internet but LyX itself does not yet have one. The next major LyX version 2.0 will 
have one.


The template can be found here as ZIP-file:
http://fkurth.de/uwest/LyX/ThesisTemplate/Diss-Template.zip

It is designed to give people a starting point. The template is slightly minimalistic but highly 
customizable. It shows how to handle child documents and section headers.
The included BibTeX example files gives an overview about the different possible BibTeX entries and 
their formattings (e.g. how to handle chemical equations in titles, or how to cite standards).


Please give it a try and report what you think that should be changed.

thanks and regards
Uwe

RE: Realistic Size Limit in LyX

[Rob Oakes]

Dear LyX Users,

Thank you everyone for the very helpful recommendations.  I finally narrowed 
down what my problem was.  Turns out, it wasn't related to RAM, LaTeX, LyX or 
number of floats.   (Just for the record, XeLaTeX and LyX 2.0 are doing a 
marvelous job with 153 figure and table floats and more than 300 individual 
images.  I think that is rather neat.)

The problem is related to my very complicated Ubuntu installation.  I've been 
using LyX from within a VMware virtual machine on my MacBook Pro.  I do this 
because managing packages within Ubuntu is very easy and trying to make things 
work on Mac can be very hard.  (After much trial and error and otherwise head 
banging, I've just decided to run a virtual instance of Ubuntu.)

Anyway ... I have a number of shared directories so that I can access my files 
from both operating systems.  I've noticed on a number of occasions that Ubuntu 
crawls to a halt if the drive happens to be busy.  I think this is due to the 
way that VMware implements shared folders, but I honestly don't know.  But as 
all of my files are stored on the main hard drive (not in the virtual machine), 
launching xelatex with a large file will often cause Vmware to hang.  It also 
so happens that trying to convert a large SVN repository to a Bzr branch will 
cause the same thing.

For the past three days, I have been converting one of our larger SVN repos 
into a Bzr branch so that we could open source the code (of course, this was 
being done in the Ubuntu virtual machine).  As soon as the conversion finished, 
I found that I was no longer able to reproduce my problem.  The book magically 
started to compile without problems.

It turns out that the errors I was receiving were due to individual instances 
of xelatex  stalling and then getting killed by the OS.  That is why I was 
seeing bizarre errors in the debug screen of LyX, the xelatex jobs weren't 
finishing completely and subsequent runs were unable to correctly parse the 
code.  Once the hard drive was no longer busy, xelatex was able to successfully 
complete it's run and create a beautiful PDF of the book.

Not sure what the moral of this story should be, but at least I can report that 
the problem has been solved.

Cheers,

Rob

If it helps, I have written a document with 197 floats on 165 pages in the 
output PDF file.  While working on it, I did have problems with floats.  Here 
is how I fixed it:

1. Put the following in the Preamble:
  \usepackage{morefloats}
  \renewcommand{\bottomfraction}{.7}
  \renewcommand{\textfraction}{.05}

2. Put \clearpage (in ERT) at the end of each of 12 chapters.

That's all it took.  I did this over two years ago, when I was a few versions 
back for LyX, and I think I was still using a fairly ancient version of TeTeX.

bubbles IDE... making a splash. Some ideas useful for organizing text too (LyX could adopt)

[Jose Quesada]

Hi All,

There's a new concept for an IDE going around.
It's called bubbles IDE... making a splash. From slashdot:
covered on hacker news too http://news.ycombinator.com/item?id=1181742
*A team at Brown University has developed an IDE for Java called Code
Bubbles that makes a fairly radical departure from current IDEs — it is based
on fragments instead of
files
. *
 Some ideas useful for organizing text too (LyX could adopt). The basic
idea: Mindmap + IDE = great

The way I write in LyX uses many files. In many editors there's a clumsiness
of going from one file to another and then back to the original. This bubble
idea could go a long way.

I thought I'd drop it here. LyX has the best outliner I know of, but it'd be
good to keep an eye on new concepts.

Best,

I have texlive-2007 deb/ubuntu packages (executables in /usr/bin)
and the texlive-2009 in /usr/local directory (executables in ... see below)
By default LyX use 2009 because in my .bashrc file I added the line

PATH=/usr/local/texlive/2009/bin/x86_64-linux:$PATH; export PATH

Then the active latex is 2009.

If I want to test anything using texlive-2007 (hardly ever),
I comment (#) the above line and then the active latex is the
one from the default PATH, i.e. /usr/bin, i.e. texlive-2007.  

You can test the running latex with 'tex --version' command

That will steer you to one or the other version of the LaTeX executable, 
but what happens when it tries to load a class or style file -- will it 
look in the correct texmf database?  If latex runs another executable, 
will it grab the right one, or the first one on the system command path?


There should be a way to specify the TeX tree root via an environment 
variable (and run LyX within a shell that sets the variable one way or 
the other), but I don't know it off hand.

But the order you put paths there determines the order LyX will check
for executables like latex, so I think changing the PATH prefix will
do what you want. (I haven't tested it, though.)

OK. Interesting. In fact it has been removed because it could be wrongfully
exploited. See this post [1] from Angus Leeming:

"Interestingly, the LyX 1.4.x series uses the converter mechanism to 
convert files. Ie, the "Update Command" line no longer exists in the

Good luck navigating the unconventional interface. Once you change the formats
you actually create a new converter. Did it work?

External material is the only option if the stuff to be included is not suited
for a \includegraphics command. In your case you can do it either way. It seems
more natural to use Insert > Graphics.

Sorry, I must have misunderstood what you are trying to accomplish.  If you
insert Clear Double Page in a two-sided document, what follows will start on a
odd page.  That could require an entire blank even page to be inserted in the
output, if necessary.  That's what I would expect in two-sided documents; books,

This is possible. But every section in your document should have the 
same color to get a readable book.
(Personally, I don't think it is a good idea to change the background 
color. If colors are really necessary, then better change the color of 
the text.)


I attached a LyX file where I colored the background of all section 
headings and the text color of all subsection headings.


Some further hints for writing a book:

- Better use the book (KOMA-script) or memoir document class. These 
classes provide much more featues than the default book class. For 
example automatic print space calculation, title page formatting, 
binding correction, etc.
(The LyX UserGuide is an example how the power of KOMA-script is uses - 
look at its document settings.)


- If possible, use short titles for all section headings that are 
running in the PDF-output over more than one line. Otherwise the table 
of contents and the PDF bookmarks would become unreadable.


- Don't overuse colors and horizontal lines. Good books use both very 
rarely.

The UI is somewhat strange in this area. You can modify an existing
converter + its input/output formats and it will be saved as a new
converter.

Consider a name more specific than Python as input format description,
as there could be also Python scripts requiring other processing or
resulting in a different output format.

There is external material that does not fit in the converter tool
paradiga. Also, with 'external inset' you can specify parameters in the
LyX document. If these are not needed, defining a Converter is simpler
and enables a preview.

Re: Realistic Size Limit in LyX

[Helge Hafting]

Rob Oakes wrote:

Dear LyX Users,

 


Is anyone aware if there is a realistic limitation on the number of images
you can have in a long document (or the size of the resultant PDF)?
Yesterday, I've run into a problem that I don't know how to solve.

 


I have been working on the "Writing with open source tools" book, but my
overall PDF master document will no longer build.  It fails with an
extremely obscure errors.  Though they vary, the most common contain
reference to:



@@BOOKMARK

 


What is truly bizarre, however, is that if I remove one of several chapter
that has a very large number of images (examples, screenshots, etc), then
the book will compile without problem.  It does not seem to matter which,
I've tested several different configurations and it seems to be overall
number of images that is the problem.  (Also, I've tested all of the
individual chapter files that have been removed, and they all compile.)

 


I am also seeing errors in the debug output (I'm using an SVN version), and
it appears as though the worker thread is timing out.

 


Does anyone know what might be the cause of these problems?  Does LyX or
LaTeX have any kind of limit on the number of files that it can
realistically handle?  I'd be extremely appreciative of any advice.


I don't know of any limits in LyX, except for whatever limits your pc
and operating system have. Hitting those is not likely.

Latex have various limitations, especially for floating material. Is 
your graphics in floats? Floats may float around, bumping into other 
floats. There are some limits on how many floats latex can consider at

the same time.

If "Insert->Formatting->Clearpage" between your floats help, then
you probably hit some obscure "too many simultaneous floats" limit.

Same diagnosis if removing every other float in the chapter helps.
To distinguish between "too many floats" and "too many graphics files",
try dissolving floats instead of removing them. (i.e. the image remain
in the text, but non-floating.) If it helps, then you had a float
problem. If not, then you might have a problem with many files. Try
removing some.

Destructive tests are best done on a copy of your book. :-)

Possible fixes for float problems:
* Upgrade your latex, if possible. May also help with
  other limits.
* Make sure you don't have an "unplaceable float". Typically
  one that is bigger than a page, so it forces all floats
  to the end of the chapter/book. And that don't work
  if there are "too many".
* Fewer floats, but you probably doesn't want that.
* More text between floats, so one float can be placed before
  the next is issued. If some "clearpages" help, then more
  text in those locations will help too.
  If you started by outlining with some headings and then
  added all your figures before writing the text, then
  you might get such trouble.
* Merge adjacent floats into a single float containing
  several figures. (You can still have several numbered captions
  and cross-reference each of them.)
* Reduce the size of some figures, placement becomes easier
  for latex.

If your problems aren't float-related, then this isn't
likely to help.

I saw it in another posting to this list, and there's a few other similar 
examples that use it on the web:

I can define a new Python file format, but strangely, no matter what I do the 
"Add" button
in the converters section is greyed out. I can only create the converter by 
editing
and saving over an existing converter in the list.

Makes sense, but then what are the external material templates actually meant 
to be used for?

Yes, Python is on the path. I tried putting the full path to Python in the 
UpdateCommand as well but that didn't work either. I don't think it's a path 
issue because even a command like "echo test> output.txt" does not work.

If I first run the Python script manually and then try exporting the Lyx 
document to PDF (pdflatex), I still get this error:

"Missing $ inserted. Missing { inserted. I've inserted a
begin-math/end-math symbol since I think you left one out. Proceed,
with fingers crossed."

However, if I export to LaTeX (pdflatex), and then open this LaTeX file in 
TeXnicCenter, I can export to PDF with no problems and the Python-generated 
figure shows up correctly.

I tried putting everything in to the root directory C:\ but had the same 
problem.
