Re: Reducing the number of pages in an article

[Daniel Lohmann]

If you compile with pdflatex to pdf, you might also consider loading the 
microtype package in your preamble:

\usepackage{microtype}

Not only this improves the typographical aesthetics of your document, I have 
also found it reducing the number of pages slightly (by about a quarter page 
per ten pages in a two-column style, that is by about 2-3%, which might be 
enough in your case.)

More evil hacks include:

- explicitly putting negative vskips (e.g., \vskip{-2ex}) to reduce the spacing 
between certain figure floats and the following text or between the figure and 
its caption.

- explicitly enlarging the one or other page by a single line 
(\enlargethispage{\baselineskip})

two. In the example I have used the plus symbol (+) as delimiter to split the 
arguments; the delimiter itself is not printed.  However, you might use 
whatever you want to delimit the arguments, even complex tokens:

 Thanks, Daniel, for sharing this solution.  

 Which style file are we talking about?  

The beamer theme I have developed for my department. Its a complete own theme 
that is included with \usetheme{i4} in your preamble and has to be put 
somewhere in your texmf-tree (or side by side to the presentation). I have 
zipped it together with a small example:
  http://www4.informatik.uni-erlangen.de/~lohmann/download/i4beamer.zip

As a (somewhat bigger) example I have also provided the Puma-Talk:
  http://www4.informatik.uni-erlangen.de/~lohmann/download/puma-slides.zip

Here I have put the style side by side to the presentation, as I was 
collaborating with a colleague on that.
DISCLAIMER: As most of my talks, this one went through some last-minute 
optimization that partly lead to, well, not so nice code.

 Since examples are the best teachers, could you please upload (or point to) a 
 Lyx file to produce (part of?) the very nice presentation of PUMA that was 
 showcased on your last message?

Sorry, there is no LyX file. I considered the discussion to be already at a 
point how to achieve such things with beamer at all.

I personally do not consider LyX to be the right front end for beamer. In my 
presentations, I tend to use a lot of visual effects and as little plain text 
as possible. The visual effects are mostly achieved with TikZ and some LaTeX 
(and sometimes even plain TeX) coding, which means that within LyX I would end 
up with 80% ERT, which would be a PITA. LyX is definitely not my editor of 
choice for LaTeX code.

Even though I never have tried it: the theme should be usable together with LyX 
as good (or as bad) as any Beamer theme, so feel free to experiment with it.

 Daniel, your solution inspired me to solve the other Beamer problem I'd been

 altered by a \setlength{\textwidth}, but no matter what I did with \center, 
 \centering, \hskip, \leftskip, I couldn't center it.

Yeah, this LaTeX center commands are all a bit strange wrt when they work and 
when not; I have never really understood it. The one that works for me is the 
center *environment*. I usually combine it with minipages to achieve the 
desired text width:

 \begin{center}\begin{minipage}{0.8\textwidth}
   BLOCK 
\end{minipage}\end{center}


 Ehud and Daniel, what other Beamer difficulties can you think of? I'm having 
 a 
 lot of trouble getting onto the Beamer-Latex mailing list, so this is the 
 most 
 authoritative Beamer knowledge source I have.


There is probably plenty to say that (even more probably) I have forgot 
meanwhile. So, to just get this started:

** absolute positioning of elements.
IMHO an essential for presentation slides, but not natively supported by 
beamer. I ended up with using TikZ pictures with the [overlay] option and the 
(current page) node to achieve this (see the puma-slides example). In fact, 
TikZ has come to my rescue in many more cases, so I use it quite a lot in 
conjunction with beamer. A major downside of employing TikZ quite a lot, is, 
however...

** long compilation times.
I use the comment package (\begin{comment} ... \end{comment} to uncomment 
during authoring those parts of a presentation I am currently not working on.

** reusability of frames.
This is an issue I do not yet have found a good solution for. In theory, beamer 
frames should be simply reusable, that is, just copy the \begin{frame} ... 
\end{frame} block into your new presentation  -- right? 
In practice, this only works for the most trivial slides. LaTeX is all about 
easing your life with macros, packages, styles, and so on and I use all of it 
quite a lot. The downside is that after a while it is no longer obvious on 
which packages, listing-styles, tikz-styles, color definitions, custom macros, 
and so on -- all that stuff one usually puts (or has to put) in the preamble -- 
a certain frame depends. Things become even worse in a collaborative 
environment, where each of your colleagues has her own tool kit in this 
respect. An attempt to reuse just three slides from a colleague in one of my 
lectures turned out to be multi-hour project, because of such subtle 
dependencies, especially those that do not show up at compilation time, but 
just make the result looking weird, are hard to debug.

that is included with \usetheme{i4} in your preamble and has to be put 
somewhere in your texmf-tree (or side by side to the presentation). I have 
zipped it together with a small example:
  http://www4.informatik.uni-erlangen.de/~lohmann/download/i4beamer.zip

As a (somewhat bigger) example I have also provided the Puma-Talk:
  http://www4.informatik.uni-erlangen.de/~lohmann/download/puma-slides.zip

Here I have put the style side by side to the presentation, as I was 
collaborating with a colleague on that.
DISCLAIMER: As most of my talks, this one went through some last-minute 
optimization that partly lead to, well, not so nice code.

 Since examples are the best teachers, could you please upload (or point to) a 
 Lyx file to produce (part of?) the very nice presentation of PUMA that was 
 showcased on your last message?

Sorry, there is no LyX file. I considered the discussion to be already at a 
point how to achieve such things with beamer at all.

I personally do not consider LyX to be the right front end for beamer. In my 
presentations, I tend to use a lot of visual effects and as little plain text 
as possible. The visual effects are mostly achieved with TikZ and some LaTeX 
(and sometimes even plain TeX) coding, which means that within LyX I would end 
up with 80% ERT, which would be a PITA. LyX is definitely not my editor of 
choice for LaTeX code.

Even though I never have tried it: the theme should be usable together with LyX 
as good (or as bad) as any Beamer theme, so feel free to experiment with it.

Yeah, this LaTeX center commands are all a bit strange wrt when they work and

 Ehud and Daniel, what other Beamer difficulties can you think of? I'm having 
 a 
 lot of trouble getting onto the Beamer-Latex mailing list, so this is the 
 most 
 authoritative Beamer knowledge source I have.


There is probably plenty to say that (even more probably) I have forgot 
meanwhile. So, to just get this started:

** absolute positioning of elements.
IMHO an essential for presentation slides, but not natively supported by 
beamer. I ended up with using TikZ pictures with the [overlay] option and the 
(current page) node to achieve this (see the puma-slides example). In fact, 
TikZ has come to my rescue in many more cases, so I use it quite a lot in 
conjunction with beamer. A major downside of employing TikZ quite a lot, is, 
however...

** long compilation times.
I use the comment package (\begin{comment} ... \end{comment} to uncomment 
during authoring those parts of a presentation I am currently not working on.

** reusability of frames.
This is an issue I do not yet have found a good solution for. In theory, beamer 
frames should be simply reusable, that is, just copy the \begin{frame} ... 
\end{frame} block into your new presentation  -- right? 
In practice, this only works for the most trivial slides. LaTeX is all about 
easing your life with macros, packages, styles, and so on and I use all of it 
quite a lot. The downside is that after a while it is no longer obvious on 
which packages, listing-styles, tikz-styles, color definitions, custom macros, 
and so on -- all that stuff one usually puts (or has to put) in the preamble -- 
a certain frame depends. Things become even worse in a collaborative 
environment, where each of your colleagues has her own tool kit in this 
respect. An attempt to reuse just three slides from a colleague in one of my 
lectures turned out to be multi-hour project, because of such subtle 
dependencies, especially those that do not show up at compilation time, but 
just make the result looking weird, are hard to debug.

Steve (and others),

I know that you a are a friend of pragmatic solutions (recalling the recurring 
discussion on how to do the front matter), so here is mine with respect to 
beamer, which kind of resembles your front-matter approach :-)

I tried for about a day to implement my group's slide style with beamer, 
including a logo on every slide, of course, but also some other graphical 
elements. (If there is one thing I really dislike about beamer than it are the 
standard styles. I have seen them just too many times, they look all the same. 
IMHO, it should not be overly obvious to the audience which tool the presenter 
has used to create her presentation!)

After fiddling around just too long with pgfimage and Co I gave up and went for 
the brute force approach. I draw the slide style with my graphics program of 
choice into an PDF image of exactly 128x96 mm (the dimensions of a beamer 
slide). Then I install this as the background image on every page. I do not 
use any additional beamer style stuff, and -- voila, there we are. In the style 
file this looks as follows:

%
% background image setup
%
% This is the real trick :-) All graphical elements of the i4-layout are just
% in the background image. To support the plain-option for frames, we actually
% need two different background images (and probably a third one for the title
% slide, don't know yet)
%
%
  \usebackgroundtemplate{
\ifbea...@plainframe%
  \includegraphics[width=\paperwidth]{beamerthemei4_bgplain}%
\else %
  \includegraphics[width=\paperwidth]{beamerthemei4_bg}
\fi%
  }

Of course, this approach is not really the beamer philosophy. You cannot 
combine it as smoothly with outer styles, inner styles, and all this stuff ... 
but what the heck -- I do not need (pseudo-) variety, I need just ONE style 
done right.

Assuming you are compiling with pdftex as backend (which is most probably the

when compiling to dvi), you can use the  \pdffilemoddate{filename} built-in

LyXically and applied for the own source file this comes down to the following 
two lines, which should be inserted into your document's preamble:

\date{\expandafter\parsedate\pdffilemoddate{\jobname.tex}\empty}

(You can alter the display format, e.g., to use full stops instead of hyphens 
as separators, by modifying the \empty{} part of the first line.

I have found the basics of this trick on the net some time ago, so I do not

works for the years 2000 -- 2099.

I have found the xstring package, which provides a \StrRemoveBraces command 
that helps here:

\usepackage{xstring}
\strremovebraces{\in...@path\jobname.lyx}[\lyxfilepath]
\def\parsedate #1:20#2#3#4#5#6#7#8\empty{20#2#3/#4#5/#6#7}
\date{\expandafter\parsedate\pdffilemoddate{\lyxfilepath}\empty}

Attached is a .lyx-file that demonstrate this.

Nevertheless, I would prefer a solution that does not employ xstring.

I have found the xstring package, which provides a \StrRemoveBraces command

\def\parsedate #1:20#2#3#4#5#6#7#8\empty{20#2#3/#4#5/#6#7}
\date{\expandafter\parsedate\pdffilemoddate{\lyxfilepath}\empty}

Attached is a .lyx-file that demonstrate this.

Nevertheless, I would prefer a solution that does not employ xstring.

Assuming you are compiling with pdftex as backend (which is most probably the 
case, as all more or less recent LaTeX-Distributions use it by default -- even 
when compiling to dvi), you can use the  \pdffilemoddate{} built-in 
command to retrieve the "last modified" date of . 

LyXically and applied for the own source file this comes down to the following 
two lines, which should be inserted into your document's preamble:

\def\parsedate #1:20#2#3#4#5#6#7#8\empty{20#2#3/#4#5/#6#7}
\date{\expandafter\parsedate\pdffilemoddate{\jobname.tex}\empty}

(You can alter the display format, e.g., to use full stops instead of hyphens 
as separators, by modifying the \empty{} part of the first line.

I have found the basics of this trick on the net some time ago, so I do not 
want claim authorship for it. Note that in its current form \parsedate only 
works for the years 2000 -- 2099.

Stefano, you are right, of course!

We need the path to the LyX-File, not to the generated .tex file:

\date{\expandafter\parsedate\pdffilemoddate{/Users/lohmann/test.lyx}\empty}

However, I would prefer not to hard-code the absolute path to the LyX file. 
Fortunately, LyX defines \in...@path in the preamble as the file path to the 
LyX-file directory:

\def\in...@path{{/Users/lohmann//}}

However, the following does /not/ work:

\date{\expandafter\parsedate\pdffilemoddate{\in...@path\jobname.lyx}\empty}

Apparently, the problem is the double curly braces that LyX uses in the 
definition of \in...@path and that somehow influence the TeX-internal scanning; 
with the following definition it /would/ work: 

\def\in...@path{/Users/lohmann//}

Does anybody know, how to expand \in...@path in a way that the double curly

 If so, then I would think the workflow could look like this. You create two 
 separate documents: a LyX document for the text, and a presentation document, 
 for which you could use OpenOffice Impress or LyX itself, via the Beamer 
 class, or you could stick with PowerPoint. You print the presentation 
 document as a PDF and then use something like pdftoppm to convert the pages 
 of the pdf to images. The images themselves can then be inserted into the LyX 
 document in the usual way. Since all of this is just running a bunch of 
 programs, it could all be automated, even, though you might have to check the 
 image names manually, as they could change if you'd added or removed pages.

It's even easier than that as LyX/Latex (\includegraphics) can directly embed a 
certain page of a PDF file as graphics. 

The general idea is to have the slides as external material that is *referenced 
from* the textbook document instead of *copied into* it, so that whenever a 
silde changes, it also changes in the textbook. Note: While I surely would like 
to convince you to use LyX, this should be possible with Word as well (at least 
it used to be possible ten years ago).

Re: Convert Comment into Marginal Note

[Daniel Lohmann]

Hi Diego,

I did something similar for lyxgreyedout in my dissertation. The  
caveat is that both., lyxgreyedout and comment are environments,  
whereas marginpar is a command. So actually you are looking for a  
technique to grab the content of an environment in a way it can be  
passed to a command.


After hours of googling I had found the trick. The amsmath package  
provides  a fairly magic macro called \coll...@body to perform this  
task.


I have added the respective lines from my thesis preamble. I developed  
three variants to typeset the comments, but don't know if the  
marginpar variant ever really worked. The tikz variant was way  
cooler :-)



Have fun,

Daniel

You thought you changed font over a selection of text, but only the

You have most probably used a command instead of a declaration. The  
command should take the text as its argument. If you don't group the  
text, only the first character will be passed as the argument.


What I don't know and wasn't able to find is how to group the text.

You thought you changed font over a selection of text, but only the  
first character has come out in the new font.
You have most probably used a command instead of a declaration. The  
command should take the text as its argument. If you don't group the  
text, only the first character will be passed as the argument.


What I don't know and wasn't able to find is how to group the text.

Hope someone could help me :-)

Re: Convert "Comment" into "Marginal Note"

[Daniel Lohmann]

Hi Diego,

I did something similar for "lyxgreyedout" in my dissertation. The  
caveat is that both., "lyxgreyedout" and "comment" are environments,  
whereas marginpar is a command. So actually you are looking for a  
technique to grab the content of an environment in a way it can be  
passed to a command.


After hours of googling I had found the trick. The amsmath package  
provides  a fairly magic macro called \coll...@body to perform this  
task.


I have added the respective lines from my thesis preamble. I developed  
three variants to typeset the comments, but don't know if the  
marginpar variant ever really worked. The tikz variant was way  
cooler :-)



Have fun,

Daniel

Re: floats and subfloats with longtables SOLVED

[Daniel Lohmann]

Hi Rob,

a clean solution might be possible using the afterpage package.  
Basically it provides the \afterpage{something} command, which  
causes the expansion of something to be postponed until LaTeX has  
shipped out the current page. If you insert your long table this way,  
it should (theoretically) appear on the beginning of the next page  
without interrupting the flow of text on the current page.

Re: Lining up text and graphics in tables?

[Daniel Lohmann]

Thanks Daniel,

Yeah, I tried a minipage containing three minipages just before I  
wrote the

original email. It walked waay off the right side of the page.

Hmmm, but I didn't try the textwidth and hfill. Where would I place  
the
\textwidth, and how would I back it out once all these triples are  
complete?




Hi Steve,

the width of the minipage can be set up in its settings; the hfill can  
be entered in LyX via Insert-Formatting-Horizontal Space  
However, never mind -- the hfill trick works only with two columns,  
for three we need to do something different.


Attached is a LyX file with three minipages in a row. I have set the  
width of each minipage to 0.3\textwidth (30 textwidth% in the LyX  
minpage settings) and inserted a horizontal space of 0.05\textwidth (5  
textwidth%) in between, so the complete row should sum up to 100  
textwidth%.


The spacing has to be done via ERT, as LyX does not allow to enter  
relative dimensions in the Horizontal Space dialog.


It's pretty obvious -- once you have seen it. Well LyX and LaTeX tend  
to be like that :-)

textwidth%) in between, so the complete row should sum up to 100  
textwidth%.


The spacing has to be done via ERT, as LyX does not allow to enter  
relative dimensions in the "Horizontal Space" dialog.


It's pretty obvious -- once you have seen it. Well LyX and LaTeX tend  
to be like that :-)


Have fun,

Re: Lining up text and graphics in tables?

Hi Steve,

have you tried using minipages instead? In my experience they tend to  
be less fragile than tables. I have never tried 3 columns (just 2 so  
far), but that shouldn't matter. Just insert 3 minipages side by side  
with a width of 33% \textwidth and a \hfill in between.

Hey Petr,

Thanks for all the hard work on LyZ. I haven't checked out Zotero for  
a while; liked it a lot, but the integration with LyX was odd and it  
tended to corrupt my bibtex databases. However, with LyZ I will give  
it another try.


I just want to put emphasize the importance of customizable citation  
keys! Many of us work in collaborative environments with shared bibtex  
databases and specific home grown requirements on how the keys are  
made up. For instance, in our group this is:
 author:two-digit-year:venue (with venue being an  
abbreviation for the conference or journal the paper appeared.)
In fact, in my group this it has always been the number one argument  
against bibtex frontend XYZ that it does not get the keys right.


Having said that, I would appreciate an even better configurability of  
the key generation. What I would really like is the option to enter an  
advanced formatting string to generate the keys, including besides the  
variables for author, year, etc. various formatting specifiers and  
conditionals, such as:

- number of digits (e.g., use only the two last digits of the year)
- upper case/lower vase (very important, unfortunately very few tools  
support this)
- conditionals (e.g., @book entries do not have a venue; URLs do not  
have a year and the venue is 'site')

- ...

Another important point in which most, if not all, bibtex frontends  
fail miserably is the requirement to be minimally invasive on the  
bibtex database. Some collaborators still prefer editing the database  
with a text editor. What I expect from  a good frontend is that it  
leaves all entries alone in the file that have not been modified in  
the current session,  including formatting, LaTeX comment lines  
beginning with %, and so on. Basically, if I use your tool to add or  
edit an entry 'foobar' and update the bibtex file underneath, the the  
diff to the previous version of the bibtex file should contain only  
lines that are related to the 'foobar' entry.


Just my 2 items on the long-term wish list :-)

without looking into the code, creating tikz->png convertor wont help?
pavel


Just to close this thread:

Defining an additional tikz->png converter does indeed solve the  
problem. Another possible solution is to extend the convertDefault.py  
script to recognize "TikZ:" as input format. For convenience reasons,  
this is the route I have been taking.



If others would like to try this:  Here are the step-by-step  
instructions:


-- Under [File Handling --> File formats] add a new file format "TikZ"  
as Vector graphics format,Short Name: "Tikz", Extension: "tikz",  
and Editor: "vim".


-- Under [File Handling --> Converters] add a Converter Definition  
"TikZ --> PDF (ps2pdf)"with Converter: "pdflatex - 
interaction=nonstopmode $$i"


-- Replace the convertDefault.py script by the attached version.

Disclaimer: This are my very first lines of Python code!

Note: According to the docs, it should be enough to put the customized  
version of convertDefault.py into $LYXUSER/scripts (~/Library/ 
Application Support/Lyx-1.x on the Mac). However, on my system (Mac OS  
X, LyX 1.6.3) it seems to remain unrecognized in this position, so I  
ended up with replacing the default version.

Rather, I think you just want to include the tikz code itself. You can
just use input on the TikZ figure itself. If you put that inside a LyX
floating graphic or a minipage, it just works in the final
processing. In Lyx, choose Insert File Child Document and then
choose your tikz text file.  As long as it is just the figure, it is
all good. I've just tested it, and it does work.

But you won't get an in-document preview in LyX without a  bit of

the Dia code has a good idea.  I've tried to figure that part out, but
no solution yet. We need a way to tell LyX to pass the Tikz figure
code straight through to LaTeX, but we also want an on-screen preview
of what that will be like.  But it is inherently impossible to get a
preview of what that will be like without compiling the whole
document.  A conundrum for me.


Paul,

Your comments are very valid, but I intentionally want to have the  
possibility to compile the TikZ-figures externally and embedd them as  
PDF:


- TikZ can increase compilation times *dramatically*. If you embed  
dozens of nontrivial TikZ figures as code into your document,  
compilation of your LyX document may take minutes instead of seconds.
- During the development of the TikZ figures (a time-consuming process  
of its own) I need to compile and debug them stand alone with short  
roundtrip times.

- PDF images are much easier to scale (to, e.g, pagewidth)
- Regarding the font (and styles and colors...) issue: I solve it by  
setting that up in a common preamble that is \input'ed into the LyX  
document and the TikZ figures. However, on some (rare) occasions I  
*want* to have different fonts in the figure than in the document.  
This, again, is easy to achieve via the PDF route, but requires quite  
same hacking if the figure is embedded into the source.


In fact, I can imagine only one situation I would prefer embedding  
TikZ figures by source: If they contain references into other parts  
of  the document (such as clicking on a TikZ node should bring you to  
page 212 or you refer to some bibliography item within the figure).

Hi,

Even though I consider myself a LyX master in many respects, the  
exact usage of File Formats, Converters and External  
Material... have always remained a mystery to me. Today I gave it  
another try (LyX 1.6.3-mac) -- and failed again.


So here is what I want to achieve:

I have some TikZ figures (which are actually stand-alone LaTeX- 
documents with the extension .tikz) that I want to embed (not the  
source, but the PDF/EPS via \includegraphics) into my LyX document  
in a way that (1) the LyX-Preview does work (2) PDF generation does  
work, and (3) the .tikz-file is opened in vim when I select Edit  
externally...


So far I got (2) and (3) working, but not (1):

-- Under [File Handling -- File formats] I have added a new file  
format TikZ as Vector graphics format,Short Name: Tikz,  
Extension: tikz, and Editor: vim.


-- Under [File Handling -- Converters] I have added a Converter  
Definition TikZ -- PDF (ps2pdf)with Converter: pdflatex $$i


If I now embed a .tikz-file, external editing and PDF generation  
works fine, but LyX is not able to show a preview. As I interpret  
the output of lyx -dbg graphics, LyX does not know how to  
generate a pixmap  from the input format (TikZ). Do I have to  
define a converter to some pixmap format as well?  How to do so?

Hi Pavel,

Thanks for your answer!

However, I have to admit that I don't really get what you suggest me  
to do. As I read 27914, this introduces Dia support via  
external_templates. Does that mean that it is *not possible* to  
achieve goal (1) (the preview in LyX, everything else works) via file  
formats and converters only?  Do I have to go the external_templates  
route?


Thanks!

Daniel




Hi,

Even though I consider myself a LyX master in many respects, the  
exact usage of File Formats, Converters and External  
Material... have always remained a mystery to me. Today I gave it  
another try (LyX 1.6.3-mac) -- and failed again.


So here is what I want to achieve:

I have some TikZ figures (which are actually stand-alone LaTeX- 
documents with the extension .tikz) that I want to embed (not the  
source, but the PDF/EPS via \includegraphics) into my LyX document  
in a way that (1) the LyX-Preview does work (2) PDF generation does  
work, and (3) the .tikz-file is opened in vim when I select Edit  
externally...


So far I got (2) and (3) working, but not (1):

-- Under [File Handling -- File formats] I have added a new file  
format TikZ as Vector graphics format,Short Name: Tikz,  
Extension: tikz, and Editor: vim.


-- Under [File Handling -- Converters] I have added a Converter  
Definition TikZ -- PDF (ps2pdf)with Converter: pdflatex $$i


If I now embed a .tikz-file, external editing and PDF generation  
works fine, but LyX is not able to show a preview. As I interpret  
the output of lyx -dbg graphics, LyX does not know how to  
generate a pixmap  from the input format (TikZ). Do I have to  
define a converter to some pixmap format as well?  How to do so?


This is pretty confusing. As I understand the manuals (don't  
remember where exactly I have read this) LyX should be able to

Hi Luis,

This may not be exactly the answer you are looking for :-)

IMHO the front matter (the stuff that is rendered by \maketitle) is  
the
most difficult part to get right into a LyX layout, especially with  
paper

styles. Every paper style uses different concepts on how authors,
institutions, multiple authors per institution, authors with multiple
institutions,  thanks-titlenotes, and so on have to be specified.  
So even
with the well-designed paper layout files that ship with LyX (LNCS,  
IEEE,
...) I usually end up using ERT in the front matter to get what I  
need.


So if you are not going to write dozens of articles using that  
style, I
would just not bother in getting everything right into the layout  
and use

ERT in the paper to specify the front matter.

Ok, maybe I didn't make myself clear: you can have self-contained  
archives
with no compression at all on OSX. It works like this: you make a  
directory
and in that directory you dump a special file that tells finder to  
display

the directory as a package.

But from the command line, it is still a directory. And in finder,  
you can
look into the package by choosing Show Package Contents from the  
pop up

menu.

Now Pages files for example come as such packages, you can copy that
directory around, send it through email (yea, email clients handle it
surprisingly well), and it still works.

Now, other operating systems see a directory and not a package.  
People using
something other than OSX would have to be reminded to copy the  
directory

around the .lyx file around, which would be managed by lyx.

The file would still be accessible, no performance penalty, but  
complete
send-aroundability, and while it might feel a little alien on other  
OS's, on

OSX it's the standard way to do such things, so OSX users will cheer.


No, they won't.

The thing is that OSX -- or at least the OSX applications that use  
this concept, with Pages being a good (well, bad) example -- do *not*  
treat packages as true directories, but as a personal container.  
Whenever you save a Pages document, for instance, Pages deletes  
everything in the directory that was not created by itself. This can  
be quite surprising!  Pages might also decide to rename its files in  
the directory. And so on.


All tools that need to manage side-by-side metadata in directories  
(such as CVS and SVN) are inherently unusable with OSX apps that use  
the package format. You just cannot put a Keynote presentation into an  
svn repository...


Packages are one of those OSX standards that are conceptually nice,  
but unfortunately seriously broken in the actual implementation.
