Re: problem with custom converter (bug?) - workaround provided
Hi Bogdan,
I have not yet used it myself but, it seems that this is a typical
situation to be handled with branches in Lyx, no?
One branch for only the questions and another one for questions and
answers? SO, you can selectively compile the branch that interests you.

One way to do this, then, would be (a) to define a new file format, call
it pdfx (more or less copy over the definition of the PDF (pdflatex)
format, but making that one change from pdf2 to pdfx) and then define a
custom converter for latex --> pdfx. The one for latex --> pdf2 is:
pdflatex $$i
so you'd have to get the quotes right, etc, to make that work.
Not ideal, I know. But if we fix this, it will be 2.1 before the fix is
out, since it will definitely change the file format (probably of layout
files).
Thanks for replying Richard. I already defined a new converter like
the above. I use it to compile two versions of the same problem sheet,
one with answers, one without (there is a bug with defining that
converter for which I found a workaround but I'll make a separate post
about it).
However, as you say, it's quite far from ideal for the purpose of
paper margins since I'd have to keep modifying the converter and/or
file format to fit each document margin requirements etc. Gets the job
done for now but it would quite nice to have the possibility of adding
code before calling \documentclass{} in the future. Shall I file an
enhancement request about this, pointing to this discussion?
Sure.

Re: problem with custom converter (bug?) - workaround provided
Actually, I just discovered that the expansion of $$i is put at the end
of the actual command LyX launches no matter what I use for the
converter command, e.g. if the converter command is:
pdflatexna $$i 20 20
then LyX is actually executing:
pdflatexna 20 20 sheet.tex
Nasty :)

I defined a new converter in LyX do achieve the same but I could not do

My workaround is to wrap the whole thing in a cmd script pdflatexna.bat

Biblatex-biber citation problem
Hello, I'm not sure if this is the right place for my question. In that case please either ignore my mail or give me a hint where to place the following problem: I'm using biblatex with backend=bibtex8 and wanted to change to backend=biber. The change went fine but the output of the some of the in-text citation references is now different: I'm using Natbib author/year style. In cases of electronic references (entry type "online") where no author and year are provided (but title, url and urldate) backend=bibtex8 produces the in-text citation (correctly) just with the title. But biber now adds the year of the urldate. I think this is wrong because the date of the url - producing "visited on .." - has nothing to do with the (unknown) time the page was written. Any suggestion? - In the meanwhile I stick to bibtex8 ;-) Peter
Re: Crash with language change in combination with utf8 & float tableau
Thanks for investigating and (I guess) solving the problem. Sorry, but I don't know how to compile the source myself. I will wait for the new LyX release. In the meanwhile I have found a (provisional?) solution: I converted the bib file so I don't need utf8 anymore. Peter PS.: I'm using OS 10.6.8.

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.
For the IEEEtran class for instance, the page margins can be set only
by setting some IEEEtran
latex variables before the \documentclass{} call ... the use of
geometry package or the likes is
highly discouraged for IEEEtran.
Can you please point me to the IEEEtran documentation where this is
described? No example nor the documentation of IEEEtran on CTAN
http://ctan.org/tex-archive/macros/latex/contrib/IEEEtran/
describe or use this.
Sure, the official FAQ: http://www.michaelshell.org/tex/ieeetran/
Search for the string "incorrect margins". The PDF doc of the IEEEtran
does not list many tricks.
But what exactly do you want? Can you send me a _small_ LyX file with a
short explanation?
I'm occasionally using IEEEtran in A4 paper format for other purposes
than submitting academic papers to IEEE journals/conferences. IEEEtran
fixes the content size regardless of the paper size, hence the top and
bottom paper margins become quite large when using the a4paper class
option. I want to use shorter top and bottom margins but the usage of
the geometry package is highly discouraged in conjunction with IEEEtran.
Others ran into the same issue:
http://andrejserafim.wordpress.com/2009/04/28/ieeetran-page-margins/
Being able to input code before the \documentclass call is actually not
uncommon. In fact, it is mentioned in many latex tutorials/docs
indirectly. I'm sure you all know that you can compile a latex file
either like:
pdflatex myfile.tex
or
pdflatex "\def\myvar{true}\input{myfile.tex}"
e.g. http://en.wikibooks.org/wiki/LaTeX/Customizing_LaTeX#Command-line_LaTeX
The 2nd command above is equivalent to declaring "\def\myvar{true}"
before \documentclass. This way, \myvar may be used internally by the
class, allowing fixing such things like the margin issue in IEEEtran.
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 :)
Bogdan.
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.

Highly unusual. ;-)
p.s. If not, I think this is a worthy enhancement to have in LyX.
Opinions?
If it's needed for certain classes, then it's a worthwhile enhancement.
Uwe, do you know if there's another way to do this?

example thesis template in LyX
Dear LyX users Happy New Year 2012 I have released the fifth maintenance of uthm-thesis-lyx http://code.google.com/p/uthm-thesis-lyx/ I hope this thesis example will be useful to others too. If you have any suggestions to improve this thesis template project, especially to cleanup many ERT that still appear in the text, or to simplified the LaTeX preamble, please fell free to inform me. Best regards waluyo
