Introduction and General Information
\end_layout
\begin_layout Subsection
What is LyX?
\end_layout
\begin_layout Standard
LyX is a program that provides a more modern approach to writing documents
with a computer, an approach that breaks with the obsolete tradition of
the
\begin_inset Quotes eld
\end_inset
typewriter concept.
\begin_inset Quotes erd
\end_inset
It is designed for authors who want professional output quickly with a
minimum of effort without becoming specialists in typesetting.
The job of typesetting is done mostly by the computer, not the author;
with LyX, the author can concentrate on the contents of her writing.
\end_layout
\begin_layout Standard
LyX provides an
\begin_inset Quotes eld
\end_inset
almost-WYSIWYG
\begin_inset Quotes erd
\end_inset
view of the document.
\begin_inset Quotes eld
\end_inset
Almost
\begin_inset Quotes erd
\end_inset
means that the line- and page-breaks are not displayed exactly as they
will appear in the printed document.
However, that's not really necessary, since LyX uses a separate typesetter
program (called LaTeX) to perform the final formatting of your text.
While LyX contains everything it needs to be a comfortable user interface,
the typesetting program contains everything necessary to format text, and
do so very, very well.
\end_layout
\begin_layout Standard
So, line- and page-breaks aren't your problem anymore.
Remembering which number to use for the next subsection isn't your problem
anymore.
Recalling what font you used for all of your section headings isn't your
problem anymore.
You tell LyX (and LaTeX) what
\emph on
kind
\emph default
of document you're editing and what
\emph on
type
\emph default
of paragraph this-or-that text is, the computer can typeset it accordingly.
Of course you can also still do some low-level formatting for fine-tuning.
However, the proper way with LyX is to tell the computer what the text
\emph on
is
\emph default
, not what it should look like.
So, we like to say that LyX gives you WYSIWYM editing (What You See Is
What You
\emph on
Mean
\emph default
).
\end_layout
\begin_layout Subsection
That's fine, but is it useful?
\end_layout
\begin_layout Standard

\end_layout
\begin_layout Subsection
Does LyX run on my computer?
\end_layout
\begin_layout Standard
At this time, you need to have the X Window system to run LyX.
OS/2 and Win32 ports exist, but you need to have an Xserver installed and
running on these systems.
LyX is known to run on the following platforms (and probably a zillion
others):
\end_layout
\begin_layout Itemize
Linux: RedHat 4.2, 5.0, 5.1, 6.0, 6.1, SUSE 5.x, Mandrake 7.0, 7.2
\end_layout
\begin_layout Itemize

\end_layout
\begin_layout Itemize
HP-UX
\end_layout
\begin_layout Itemize
OSF1 flore V4.0 1091 alpha
\end_layout
\begin_layout Subsection
How much hard disk space does LyX need?
\end_layout
\begin_layout Standard
On my system, the LyX binary consumes 2.0 MB of disk space, while the supporting
files occupy another 12.6 MB (9.1 MB of which is consumed by the docs! You
can delete the languages you don't care about to save some space).
Of course, you do need to have something like teTeX installed which consumes
a mere 115 MB, as well as ghostscript, which is another 10 MB!
\end_layout
\begin_layout Subsection
Is LyX really Open Source?
\end_layout
\begin_layout Standard
Yes.
The freely available X toolkit that LyX uses, xforms, was until recently
closed source.
Also the other toolkit that LyX uses, Qt, although a proprietary product
of Troll Tech, is used in its open source variant.
The LyX source itself is available under the GPL, so it qualifies.
\end_layout
\begin_layout Standard
Version 1.0 of xforms is available under the LGPL and its sources (and binaries)
can be found from
\begin_inset Flex URL
status collapsed
\begin_layout Plain Layout
http://savannah.nongnu.org/download/xforms/xforms-1.0.tar.gz

\begin_layout Section
Compatibility with other word/document processors
\end_layout
\begin_layout Subsection
Can I read/write LaTeX files?
\end_layout
\begin_layout Standard
Yes.
LyX outputs LaTeX files that are either machine or human friendly.
The
\family typewriter
tex2lyx
\family default
program that comes with LyX does a decent job of converting LaTeX into
LyX.
It's not perfect, but it will usually get at least 95% of the job done
for you.
\end_layout
\begin_layout Subsection
Can I read/write Word files?
\end_layout
\begin_layout Standard
Not trivially.
People have had some level of success with the following sequence: LyX
\begin_inset Formula $\rightarrow$
\end_inset
LaTeX
\begin_inset Formula $\rightarrow$
\end_inset
RTF
\begin_inset Formula $\rightarrow$
\end_inset
Word, and vice versa.
However, Word is inherently not a markup language like LyX and LaTeX are,
so conversions are usually difficult and almost meaningless.
\end_layout
\begin_layout Standard
However, here are a few suggestions which were sent in:
\end_layout
\begin_layout Description
word2x produces LaTeX, HTML and plain text output.
The LaTeX is importable in principle (and is rather clean) but I often
prefer plain text and add the formatting back in.
(This requires that you have knowledge on the original formatting).
On last writing did not yet handle Office 2000 Word.
\end_layout
\begin_layout Description
wvware (found at www.wvware.com, or the abisource CVS repository for the latest).
This was previously called msWordView.
Very good, only tends to produce visually formatted LaTeX/HTML.
Is however highly configurable: a config file
\family typewriter
wvLaTeX.xml
\family default
guides the translation process.
Handles also the newest Office formats.
\end_layout
\begin_layout Description
Ted This is the editor to use when someone sends you an RTF file created
by Word.
Fine product.
Mail yourself the converted version (plain text or HTML).
\end_layout
\begin_layout Standard
Finally, when all else fails, use any word processor (WordPerfect, StarOffice/Op
enOffice, ...) which understands Word.
Then export as the file as plain text and add the formatting by hand in
LyX.
\end_layout
\begin_layout Standard
For me personally, at least, it's faster doing this than cleaning up attempts
at a conversion, though it is certainly unsatisfactory if you need to go
back and forth a lot.
\end_layout
\begin_layout Subsection
Can I read/write HTML files?
\end_layout
\begin_layout Standard
You can output HTML files using the
\begin_inset Quotes eld
\end_inset
tth
\begin_inset Quotes erd
\end_inset
converter program, amongst others.
There may be a HTML
\begin_inset Formula $\rightarrow$
\end_inset
LaTeX program available which allows you to convert the other direction.

\begin_layout Section
Questions about Evil Red Text (IMPORTANT!)
\end_layout
\begin_layout Subsection
What is Evil Red Text (aka ERT)?
\end_layout
\begin_layout Standard
ERT (Evil Red Text) refers to raw LaTeX commands which are inserted into
your LyX document.
Certain troglodytes in the development group coined this term when they
complained about the unsightly appearance it leads to in LyX documents.
The more enlightened among us know that it is extremely useful, even though
it does qualify as URT (Ugly Red Text), but ERT seems to have stuck.
\end_layout
\begin_layout Subsection
How do I enter Evil Red Text?
\end_layout
\begin_layout Standard
Aesthetic arguments aside, many of the answers in this FAQ require that
you use ERT, so whenever we say
\begin_inset Quotes eld
\end_inset
insert the following LaTeX code
\begin_inset Quotes erd
\end_inset
, do the following
\end_layout
\begin_layout Enumerate
Click the TeX toolbar button or select
\family sans
\bar under
I
\bar default
nsert\SpecialChar \menuseparator
\bar under
T
\bar default
eX
\family default
.
\end_layout
\begin_layout Enumerate
Type the command as it is written in the normal way
\end_layout
\begin_layout Subsection
The new ERT inset is really inconvenient !
\end_layout
\begin_layout Standard
A lot of people have been complaining about the ERT inset introduced in
version 1.2.0.
However, since there is little hope of to see the old LaTeX font return
from the grave (it was really a hack), here are a couple of things to ponder:
\end_layout
\begin_layout Itemize
You can collapse the ERT like any other floats by using
\family sans

\begin_layout Itemize
You can also set it to
\begin_inset Quotes eld

\begin_inset Quotes erd
\end_inset
by using the properties dialog obtained by right-clicking anywhere in the

\end_layout
\begin_layout Subsection
Is there an alternative?
\end_layout
\begin_layout Standard
LaTeX commands can also be inserted in the
\begin_inset Quotes eld
\end_inset
LaTeX Preamble
\begin_inset Quotes erd
\end_inset
, a form in LyX that is inserted verbatim into the LaTeX file which is generated
during processing.
This is especially useful for including nonstandard LaTeX packages, defining
global shortcuts to be used within the document, etc.

How do I insert a fixed amount of horizontal space?
\end_layout
\begin_layout Standard
There are various ERT commands to use:
\family typewriter
\backslash
enspace
\family default
(1/2 em),
\family typewriter
\backslash
thinspace
\family default
(1/6 em),
\family typewriter
\backslash
negthinspace
\family default
(-1/6 em),
\family typewriter
\backslash
quad
\family default
(1 em),
\family typewriter
\backslash
qquad
\family default
(2 em),
\family typewriter
\backslash
hspace{
\emph on
length
\emph default
}
\family default
, etc.
An
\begin_inset Quotes eld
\end_inset
em
\begin_inset Quotes erd
\end_inset
is roughly the width of the letter
\begin_inset Quotes eld
\end_inset
m
\begin_inset Quotes erd
\end_inset
in the current font.
The length argument of the
\family typewriter
\backslash
hspace
\family default
command is any valid TeX length; units can be
\family typewriter
mm
\family default
(millimeters),
\family typewriter
cm
\family default
(centimeters),
\family typewriter
in
\family default
(inches),
\family typewriter
pt
\family default
(points = 1/72 inch),
\family typewriter
em
\family default
(width of letter
\begin_inset Quotes eld
\end_inset
m
\begin_inset Quotes erd
\end_inset
), or
\family typewriter
ex
\family default
(height of letter
\begin_inset Quotes eld
\end_inset

How can I make citations show up as [1,2,3,6] or [1-3,6] rather than [1][2][3][6
]?
\end_layout
\begin_layout Standard
Insert
\family typewriter
\backslash
usepackage{cite}
\family default
into the LaTeX preamble.
Most LaTeX distributions should have this package included.
LyX supports this package, if you insert multiple citations separated by
commas into the citation dialog, e.
g.
[Smalley_JCP,Jarrold_Sci], instead of just one citation after the other:
[Smalley_JCP] [Jarrold_Sci].

Figure related questions
\end_layout
\begin_layout Subsubsection
What is the difference between a
\begin_inset Quotes eld
\end_inset
figure
\begin_inset Quotes erd
\end_inset
and a
\begin_inset Quotes eld
\end_inset
figure float
\begin_inset Quotes erd
\end_inset
?
\end_layout
\begin_layout Standard
This is an example of less-than-ideal terminology.
\begin_inset Quotes eld
\end_inset
Figure
\begin_inset Quotes erd
\end_inset
is what I would really call a
\begin_inset Quotes eld
\end_inset
graphic
\begin_inset Quotes erd
\end_inset
; it basically means insert a picture file.
\begin_inset Quotes eld
\end_inset
Figure float
\begin_inset Quotes erd
\end_inset
is more what one means by a figure in a paper: it includes the graphic,
the caption, the figure label, etc.
You should almost always insert a figure float first, then put a figure
inside that.
\end_layout
\begin_layout Standard
Tables work in the same manner.
Put a table float in first, then insert the table within that.
\end_layout
\begin_layout Subsubsection
How do I get LyX to put the figure exactly where I want it?
\end_layout
\begin_layout Standard
Select
\family sans
Layout\SpecialChar \menuseparator
Document
\family default
.
In the
\family sans
Float Placement
\family default
box, type
\begin_inset Quotes eld
\end_inset
\family typewriter
!htp
\family default
\begin_inset Quotes erd
\end_inset
.
This tells LaTeX to try really hard to put the figure here first, then
the top of a page, then on a page by itself.
This is a global setting: all figure will then obey this rule set.
\end_layout
\begin_layout Standard
If you want to control how each figure behaves, right-click in the figure
float and you will get a dialog allowing to control the figure behavior.
\end_layout
\begin_layout Subsubsection
What does
\begin_inset Quotes eld
\end_inset
Too many unprocessed floats
\begin_inset Quotes erd
\end_inset
mean?
\end_layout
\begin_layout Standard
LaTeX can handle only a limited number of floating elements floating at
a given time.
For example, if Figure 4 can't be fit in a good location (using the default
rules of top of the page, then bottom, then a page of its own) and Figure
5 comes along, they will both continue to float toward the end of the document
until a good location can be found.
If nothing good turns up, they will just be placed at the end of the document.
If there are too many of these, LaTeX overruns a counter and emits the
\begin_inset Quotes eld
\end_inset
too many unprocessed floats
\begin_inset Quotes erd
\end_inset
error.
This is not a bug in LaTeX, this is simply too many figures with too little
text :-)
\end_layout
\begin_layout Standard
The easiest way to work around this is to insert a
\family typewriter
\backslash
clearpage
\family default
command somewhere in the document where a pagebreak would be appropriate.
While a pagebreak would simply start a new page,
\family typewriter
\backslash
clearpage
\family default
processes all remaining floats, then begins a new page.
This may lead to an unsightly stack of figures in the middle of your document;
you may need to use several
\family typewriter
\backslash
clearpages
\family default
to make things balance nicely.

Questions Related to Running LyX
\end_layout
\begin_layout Subsection
How do I convert LyX files to LaTeX from the command line?
\end_layout
\begin_layout Standard
File export was vastly improved in version 1.1.6.
Simply say
\end_layout
\begin_layout LyX-Code
lyx --export latex <yourfile>.lyx
\end_layout
\begin_layout Standard
and that is all you need to do.
\end_layout
\begin_layout Standard
If you have an older version of LyX, you can use the same syntax if you
are running X, because it will cause LyX windows to pop up onto your screen.
If you have the Xvfb command available, you can resort to a deeper level
of subterfuge (under
\family typewriter
bash
\family default
):
\end_layout
\begin_layout Standard
\family typewriter
(Xvfb :1 -once -terminate &); rm <file>.tex; lyx -display :1 --export latex
<file>.lyx
\end_layout
\begin_layout Standard
\noindent
Under csh/tcsh it is simply
\end_layout
\begin_layout Standard
\family typewriter
Xvfb :1 -once -terminate &; rm <file>.tex; lyx -display :1 --export latex
<file>.lyx
\end_layout
\begin_layout Standard

This should work anywhere, whether or not X is actually running.

Why doesn't my latest and greatest version of Ghostscript render EPS inline
figures properly?
\end_layout
\begin_layout Standard
[Note: this only applies to versions of LyX older than 1.2.0, since the graphics
rendering code has been rewritten in this version]
\end_layout
\begin_layout Standard
A couple of users reported that they couldn't get recent Ghostscript versions
to display inline figures in LyX.
It transpires that this is a Ghostscript bug:

This bug appears to affect Ghostscript 6.22 and upwards.
After applying the above mentioned patch, rendering in Lyx works fine again.
GNU Ghostscript 6.53 and above include this fix.

I want to mail someone about my problem.
\end_layout
\begin_layout Standard
Send email to the LyX Users list lyx-users@lists.lyx.org.

s' list at lyx-devel@lists.lyx.org.
\end_layout
\begin_layout Subsection
What to put in a request for help.
\end_layout
\begin_layout Standard
Include your version of LyX and a description of what you are trying to
do, along with evidence that you've actually read the docs.
\end_layout
\begin_layout Standard
If LyX has crashed, include the version of LyX, the operating system, the
version of xforms (if it seems to be a screen drawing problem), and a precise
description of the events that lead to the crash.
The easier it is for the developers to reproduce your crash, the more likely
it will get fixed.
If you're brave and like to hack, use gdb to generate a backtrace and include
the results with your mail.
If you have no clue what I'm talking about, just describe what you did
as completely as you can.
