\begin_layout Standard
eLyXer (pronounced 
\emph on
elixir
\emph default
) is a LyX to HTML converter.
 While there are a ton of such projects all over the web, eLyXer has a clear
 focus on flexibility and elegant output.
\end_layout

\begin_layout Standard

\end_layout

\begin_layout Subsection
System Requirements
\end_layout

\begin_layout Standard
eLyXer requires Python 2.3.4, and should work with versions up to 2.6.
\begin_inset Formula $x$
\end_inset

; it will convert documents generated by LyX 1.5.
\begin_inset Formula $x$
\end_inset

 to 1.6.
\begin_inset Formula $y$
\end_inset

.
 It has been tested on the most common operating systems: on Mac OS X, Linux
 and Windows, with and without CygWin.
\end_layout

\begin_layout Standard
Resource usage should be quite frugal; eLyXer runs quite happily on my 1st-gen
 Asus Eee, with its puny Celeron@570MHz and 512 MB of RAM.
 It should also be fast -- the Eee can convert ~200 pages of LyX text in
 just over 50 seconds.
 Performance is fairly linear: 200 pages take 
\begin_inset Formula $10\times$
\end_inset

 as long as 20, so there are no scalability problems.
 Memory usage stays low even when processing large documents, and conversion
 can be done on the fly (with 
\family typewriter
--lowmem
\family default
) for even lower memory requirements.
\end_layout

\begin_layout Subsection
Installation
\end_layout

\begin_layout Standard
This section looks at how to install eLyXer on your system.
\end_layout

\begin_layout Subsubsection*
Download eLyXer
\end_layout

\begin_layout Standard
First you will need to fetch the official distribution file from the 
\begin_inset CommandInset href
LatexCommand href
name "download area"
target "https://savannah.nongnu.org/files/?group=elyxer"

\end_inset

.
 Now, there is more than one way to install eLyXe, but all of them start
 by uncompressing the distributed file to a suitable directory.
 Just write at the command prompt:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 tar -xzf elyxer-
\emph on
[version]
\emph default
.tar.gz
\end_layout

\begin_layout Standard
Or for the 
\family typewriter
.zip
\family default
 version:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 unzip elyxer-
\emph on
[version]
\emph default
.zip
\end_layout

\begin_layout Standard
A directory called 
\family typewriter
elyxer
\family default
 should appear, where the main executable file 
\family typewriter
elyxer.py
\family default
 resides.
\end_layout

\begin_layout Subsubsection*
Using the Installer
\end_layout

\begin_layout Standard
An installer is provided in the root directory, called 
\family typewriter
install.py
\family default
; it is the recommended way to install eLyXer.
 To run it just type in a console as root:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
#
\color inherit
 python install.py
\end_layout

\begin_layout Standard
On Windows you can type (as a regular user):
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
>
\color inherit
 python.exe install.py
\end_layout

\begin_layout Standard
In any case, the script will look at your Python version and decide if it
 can install eLyXer as a Python module or as a binary.
 By default it will install eLyXer as a binary, so you can check if it was
 installed successfully:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 elyxer.py --help
\end_layout

\begin_layout Standard
If it is possible (i.e.
 if your Python version is above 2.3), it will also install eLyXer as a module:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 python -m elyxer --help
\end_layout

\begin_layout Standard
In any case, a brief help text and the list of command line options should
 appear.
\end_layout

\begin_layout Standard
In what follows we will assume that eLyXer has been installed as a binary,
 except where stated; substitute 
\family typewriter
"elyxer.py"
\family default
 with 
\family typewriter
"python -m elyxer"
\family default
 if your system has eLyXer as a module and you want to use it.
\end_layout

\begin_layout Standard
The installer will also copy existing translation files to your hard drive
 so that they can be used from within eLyXer for internationalization.
\end_layout

\begin_layout Subsubsection*
Prepackaged Versions
\end_layout

\begin_layout Standard
The easiest way to install eLyXer is if someone has prepackaged it for your
 system.
 Some Linux distributions include eLyXer: 
\begin_inset CommandInset href
LatexCommand href
name "Debian squeeze"
target "http://packages.debian.org/squeeze/elyxer"

\end_inset

 and 
\begin_inset CommandInset href
LatexCommand href
name "Ubuntu Lucid"
target "http://packages.ubuntu.com/lucid/elyxer"

\end_inset

.
 In this case eLyXer needs to be run as 
\family typewriter
"elyxer"
\family default
:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 elyxer --help
\end_layout

\begin_layout Standard
Another way is with the LyX installer: the 
\begin_inset CommandInset href
LatexCommand href
name "alternate LyX installer"
target "http://wiki.lyx.org/Windows/LyXWinInstaller"

\end_inset

 includes eLyXer in the default installation.
 See 
\begin_inset CommandInset ref
LatexCommand ref
reference "sub:LyX-Integration"

\end_inset

 for LyX integration.
\end_layout

\begin_layout Subsubsection*
Manual Installation
\end_layout

\begin_layout Standard
If the installer did not work for you, you can manually install it as a
 module.
 On Linux go to the elyxer directory and type, as root:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
#
\color inherit
 python setup.py install
\end_layout

\begin_layout Standard
On Windows just type:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
>
\color inherit
 python.exe setup.py install
\end_layout

\begin_layout Standard
On Mac OS X you can use sudo to have permission:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
%
\color inherit
 sudo python setup.py install
\end_layout

\begin_layout Standard
Now you can run eLyXer as a Python module:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 python -m elyxer --help
\end_layout

\begin_layout Standard
The list of command line options should appear.
 You can also manually copy the file 
\family typewriter
elyxer.py
\family default
 to a directory found in the execution path (for instance, 
\family typewriter
/usr/bin
\family default
 on Linux or 
\family typewriter
c:
\backslash
windows
\backslash
system32
\family default
 on Windows).
\end_layout

\begin_layout Subsection
Test Drive
\end_layout

\begin_layout Standard
Now you may want to try to convert the user guide:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 elyxer.py --css lyx.css --title "eLyXer User Guide" docs/userguide.lyx docs/usergu
ide2.html
\end_layout

\begin_layout Standard
or, to run eLyXer as a Python module:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 python -m elyxer --css lyx.css --title "eLyXer User Guide" docs/userguide.lyx
 docs/userguide2.html
\end_layout

\begin_layout Standard
It should generate a working web page identical to the one distributed:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 diff docs/userguide.html docs/userguide2.html
\end_layout

\begin_layout Standard
The typical output will contain just the changed lines, which in this case
 should be only the header with the file creation date.
 An example is shown on listing 
\begin_inset CommandInset ref
LatexCommand ref
reference "alg:diff"

\end_inset

.
\end_layout

\end_layout

\end_inset


\end_layout

\end_inset


\end_layout

\begin_layout Standard
If nothing else appears (i.e.
 both files are functionally equal) then everything is working fine.
 If you have 
\family typewriter
bash
\family default
 installed, to test that everything 
\emph on
really
\emph default
 works fine you can just run the included tests:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 ./run-tests
\end_layout

\begin_layout Standard
It will run a number of test and check the results, so you can see if everything
 is well.
 You also need to have installed the command-line tool 
\family typewriter
diff
\family default
 to show differences between two files.
\end_layout

\begin_layout Subsection
Usage
\end_layout

\begin_layout Standard
eLyXer is a standalone command line tool.
 It can be invoked from the command line as:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 elyxer.py [options] [source file] [destination file]
\end_layout

\begin_layout Standard
or, again for the module:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 python -m elyxer [options] [source file] [destination file]
\end_layout

\begin_layout Standard
If the source file is omitted then 
\family typewriter
STDIN
\family default
 is used; likewise, if no destination file is specified eLyXer will output
 to 
\family typewriter
STDOUT
\family default
.
 This allows its use in pipes and other flexible configurations.
 Some examples:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 elyxer.py file.lyx file.html
\end_layout

\begin_layout Standard
converts 
\family typewriter
file.lyx
\family default
 to 
\family typewriter
file.html
\family default
.
 Debug messages are shown.
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 cat file.lyx | elyxer.py > file.html
\end_layout

\begin_layout Standard
converts 
\family typewriter
file.lyx
\family default
 to 
\family typewriter
file.html
\family default
, as before.
 This time debug messages are not shown.
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 elyxer.py file.lyx | grep "<blockquote>" | wc
\end_layout

\begin_layout Standard
counts all blockquote paragraphs.
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 elyxer.py file.lyx | wget --no-check-certificate --spider -nv -F -i -
\end_layout

\begin_layout Standard
checks all external links in a document recursively.
 (Local links will appear as unresolved, but they can be ignored.)
\end_layout

\begin_layout Subsection
Image Processing
\end_layout

\begin_layout Standard
HTML pages do not contain images, as PDF documents; rather they have pointers
 to image locations on disk.
 (Luckily LyX documents are the same in this respect.) eLyXer will generate
 pages that point to the same locations as the original images, when they
 are PNG images.
 Other image types like Encapsulated PostScript cannot be used directly
 from within pages.
 If the ImageMagick package is installed eLyXer will use the 
\family typewriter
convert
\family default
 tool to create PNG versions of the images embedded in the document.
 If it is not installed eLyXer will show an error message and will not try
 to convert further images.
\end_layout

\begin_layout Standard
Image location is fragile.
 All images should be placed in the same location (and with the same structure)
 as the original document; and they should all be referenced relatively
 to the current document.
 During conversion from within LyX (in those versions where it is available)
 image locations can be lost.
 Your best bet is to do conversion in place.
\end_layout

\begin_layout Subsection
\begin_inset CommandInset label
LatexCommand label
name "sub:LyX-Integration"

\end_inset

LyX Integration
\end_layout

\begin_layout Standard
If you used the eLyXer installer LyX will automatically detect it after
 reconfiguration.
 Just make sure that you are running LyX 1.6.5 or later, and click on Tools\SpecialChar \menuseparator
Reconfi
gure.
\end_layout

\begin_layout Standard
LyX should be able to detect if eLyXer was installed as a module or as a
 binary, or even if it has been installed from a Linux distribution.
 In any case you can verify that it has been recognized by LyX by opening
 Tools\SpecialChar \menuseparator
Preferences\SpecialChar \ldots{}
, going to External formats\SpecialChar \menuseparator
Converters, and finding the
 converter for 
\begin_inset Quotes eld
\end_inset

LyX -> HTML
\begin_inset Quotes erd
\end_inset

.
 If eLyXer is there, it worked! Now you can convert your documents using
 View\SpecialChar \menuseparator
HTML.
 Otherwise try to reinstall eLyXer from scratch and then reconfigure LyX.
\end_layout

\begin_layout Section
Advanced Use
\end_layout

\begin_layout Standard
There are some advanced uses for eLyXer if you want to extract the most
 of it.
\end_layout

\begin_layout Subsection

\begin_layout Subsubsection*
Adding Options In LyX
\end_layout

\begin_layout Standard
To add one of these options so that it is used from within LyX, you have
 to modify the converter line.
 To this effect open Tools\SpecialChar \menuseparator
Preferences\SpecialChar \ldots{}
, go to External formats\SpecialChar \menuseparator
Converters,
 find the converter for 
\begin_inset Quotes eld
\end_inset

LyX -> HTML
\begin_inset Quotes erd
\end_inset

 and edit the converter line.
 It should read something like this:
\end_layout

\begin_layout LyX-Code

\family typewriter
python -m elyxer --directory $$r $$i $$o
\end_layout

\begin_layout Standard
(By default LyX will prefer to use eLyXer as a module.) If you want to generate
 pure HTML instead of XHTML, change the line to:
\end_layout

\begin_layout LyX-Code

\family typewriter
python -m elyxer 
\family default
\series bold
--html
\family typewriter
\series default
 --directory $$r $$i $$o
\end_layout

\begin_layout Standard
And so on.
 If eLyXer was only installed as a binary the original line will be:
\end_layout

\begin_layout LyX-Code

\family typewriter
elyxer.py --directory $$r $$i $$o
\end_layout

\begin_layout Standard
So you will have to change it accordingly.
 Figure 1 shows what to do to add the 
\family typewriter
--html
\family default
 option when eLyXer is installed as a module: after editing the line and
 adding the new option, click on 
\begin_inset Quotes eld
\end_inset

Modify
\begin_inset Quotes erd
\end_inset

 and then 
\begin_inset Quotes eld
\end_inset

Save
\begin_inset Quotes erd
\end_inset

 or 
\begin_inset Quotes eld
\end_inset

Apply
\begin_inset Quotes erd
\end_inset

 the changes.
\begin_inset Marginal

You should never remove the

\begin_layout Standard
This sample CSS file is published on nongnu.org and distributed along with
 the scripts, 
\family typewriter
docs/lyx.css
\family default
.
 (You may have found that your document shows minor changes in its appearance
 with time -- this is the reason.
 The main author regularly publishes a new, updated version of 
\family typewriter
lyx.css
\family default
 on nongnu.org, and all documents using it automatically appear with the
 changes.
 Backwards compatibility is maintained as much as possible.)
\end_layout

\begin_layout Standard
To give your document a customized appearance (or for pages to be accessible
 offline) you probably will want to use your own CSS file; to use it first
 copy it to the directory where your document resides (e.g.
 renaming it to 
\family typewriter
custom.css
\family default
), and customize as needed.
 Then run 
\family typewriter
elyxer.py
\family default
 with the following option:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 elyxer.py --css=custom.css document.lyx page.html
\end_layout

\begin_layout Standard
This will make the generated 
\family typewriter
page.html
\family default
 use your 
\family typewriter
custom.css
\family default
 file.
 The 
\family typewriter
`='
\family default
 sign between the constant 
\family typewriter
`--css'
\family default
 and the name of the CSS file is optional.
 More than one 
\family typewriter
--css
\family default
 option can be added if you want several CSS files to be used in the header.
\end_layout

\begin_layout Standard
Sometimes the styles in a CSS are needed in the HTML document (for offline
 viewing, or to distribute as stand-alone pages).
 For these uses there is the option 
\family typewriter
--embedcss
\family default
: the styles contained in the CSS file passed as an argument will be embedded
 in the resulting HTML document.
 For instance:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 elyxer.py --embedcss custom.css document.lyx page.html
\end_layout

\begin_layout Standard
This command generates a document 
\family typewriter
page.html
\family default
 where the styles in 
\family typewriter
custom.css
\family default
 are embedded.
 The CSS to embed must be a file, not a remote URL.
 Listing 
\begin_inset CommandInset ref
LatexCommand ref
reference "alg:embed-CSS"

\end_inset

 shows the resulting HTML header for a test CSS with just one style, 
\family typewriter
div.Standard
\family default
.
 Note that the remote CSS is still added by default; to avoid it just add
 an option with an empty CSS file, 
\family typewriter
--css=""
\family default
.

\begin_layout Subsection
Title
\end_layout

\begin_layout Standard
By default the generated web pages have the title 
\begin_inset Quotes eld
\end_inset

Converted Document
\begin_inset Quotes erd
\end_inset

.
 If a PDF title is found then it is used instead.
 The proper LyX title (a paragraph of type 
\begin_inset Quotes eld
\end_inset

Title
\begin_inset Quotes erd
\end_inset

 embedded in the text) will also be used if found.
 But when 
\family typewriter
--lowmem
\family default
 is in use eLyXer does not try to get the proper title, since it may be
 found in the middle of the document or not be present at all; scanning
 for it would mean doing two passes, one to look for the title in all the
 document and another to output the web page, and 
\family typewriter
--lowmem
\family default
 implies on-the-fly conversion to save memory.
\end_layout

\begin_layout Standard
You can change the title of the generated web page with the 
\family typewriter
--title
\family default
 option:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 elyxer.py --title "My Beautiful Document" document.lyx page.html
\end_layout

\begin_layout Subsection
Table Of Contents
\begin_inset CommandInset label
LatexCommand label
name "sub:TOC"

\end_inset


\end_layout

\begin_layout Standard
A table of contents (or TOC) can be generated for every converted LyX document.
 You can optionally also add a target frame to every link.
 The trick is to combine both options to generate a TOC that links to the
 original document on a different frame.
 For example, if the original page is called 
\family typewriter
page.html
\family default
 and you generated it with this command:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 elyxer.py document.lyx page.html
\end_layout

\begin_layout Standard
you can generate the TOC linking to this page, and at the same time point
 it to frame 
\family typewriter
contents
\family default
:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 elyxer.py --toc --toctarget page.html --target contents document.lyx page-toc.html
\end_layout

\begin_layout Standard
Then you can put it all together with a simple frameset generated manually.
 Just remember to place the original document in the frame called 
\family typewriter
contents
\family default
.

\end_layout

\begin_layout Standard
TOC generation accepts the same options as normal document conversion.
 For example, if you follow these instructions literally you will notice
 that the TOC has very wide margins and looks a bit weird; that is because
 it is using the default CSS.
 A special CSS file for TOC files is provided in 
\family typewriter
docs/toc.css
\family default
, so better results should be obtained with the 
\family typewriter
--css
\family default
 option:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 elyxer.py --toc --toctarget page.html --css docs/toc.css --target contents
 document.lyx page-toc.html
\end_layout

\begin_layout Standard
With a little bit of practice you will be able to generate useful (and nice
 looking) TOC files.
 You can see an example for the 
\begin_inset CommandInset href
LatexCommand href
name "user guide"
target "userguide-frameset.html"

\end_inset

 (if you are not already looking at it).
\end_layout

\begin_layout Subsection
Segmenting Pages
\begin_inset CommandInset label
LatexCommand label
name "sub:Segmenting-Pages"

\end_inset


\end_layout

\begin_layout Standard
Quite often you don't want a huge monolithic page, but a set of linked pages.
 To do so you can use the 
\family typewriter
--splitpart
\family default
 option, specifying the level at which eLyXer should split pages.
 For instance:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 elyxer.py --splitpart 1 document.lyx output.html
\end_layout

\begin_layout Standard
will split 
\family typewriter
document.lyx
\family default
 into pages at level 1, using 
\family typewriter
output.html
\family default
 as the root page.
 Each page will get a number that starts with 
\family typewriter
output
\family default
 and ends with 
\family typewriter
.html
\family default
, with a suffix that depends on the page -- 
\family typewriter
output-2.html
\family default
 will correspond to the second split part.
\end_layout

\begin_layout Standard
The level corresponding to 1 depends on the document class: books will be
 split at chapters, but articles will get a section per page.
 And so on with lower levels.
\end_layout

\begin_layout Subsection
HTML Code
\begin_inset CommandInset label
LatexCommand label
name "sub:HTML-Code"

\end_inset


\end_layout

\begin_layout Standard
The HTML code generated is technically XHTML Transitional, version 1.0 
\begin_inset CommandInset citation
LatexCommand cite
key "xhtml"

\end_inset

, using UTF-8 encoding.
 Some programs have (in this day and age) trouble importing XHTML, notably
 some popular word processors.
 To work around this problem and provide more flexible output in general
 you can output HTML 4.0:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 elyxer.py --html document.lyx page-to-import.html
\end_layout

\begin_layout Standard
Again, technically the code generated is HTML 4.01 Transitional 
\begin_inset CommandInset citation
LatexCommand cite
key "html-401"

\end_inset

 using UTF-8 encoding.
 Both versions should pass the W3C tests 
\begin_inset CommandInset citation
LatexCommand cite
key "w3c-validator"

\end_inset

.
 If your particular web page doesn't pass the tests, then it is a bug and
 it will be treated as such.
\end_layout

\begin_layout Standard
The CSS file for eLyXer uses some CSS2 features for math structures (fractions,
 arrays).
 This makes the output incompatible with older browsers; it requires Microsoft
 Internet Explorer 7, Firefox 3, Safari 3 or Chrome 1.
 Check the 
\begin_inset CommandInset href
LatexCommand href
name "Math Showcase"
target "math.html"

\end_inset

 to see if your browser can render eLyXer output correctly.
\end_layout

\begin_layout Subsubsection*
Character Encodings
\end_layout

\begin_layout Standard
For better browser compatibility, medium mathematical spaces are substituted
 in the output with midspaces -- improving the output for some popular browsers.
 If you want your mathematical spaces back, just use the 
\family typewriter
--unicode
\family default
 option:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 elyxer.py --unicode document.lyx page-to-import.html
\end_layout

\begin_layout Standard
Check out the 
\begin_inset CommandInset href
LatexCommand href
name "Math Showcase with Unicode"
target "math-unicode.html"

\end_inset

 to see the results.
 In the future other non-Unicode substitutions might be used.
\end_layout

\begin_layout Standard
In case you want to use the ISO-8859-15 encoding in your generated document,
 you can add the 
\family typewriter
--iso885915
\family default
 option:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 elyxer.py --iso885915 document.lyx page.html
\end_layout

\begin_layout Standard
This will make eLyXer output a document with all non-ASCII characters encoded
 as 
\family typewriter
&nbsp;
\family default
, 
\family typewriter
&#x2005;
\family default
 and so on.
 This encoding is similar to ISO-8859-1, also called Latin-1, but including
 the Euro sign.
 The 
\begin_inset CommandInset href
LatexCommand href
name "Math Showcase (ISO-8859-15 edition)"
target "math-iso885915.html"

\end_inset

 has been generated using this option.
\end_layout

\begin_layout Standard
Both encoding options can be combined with 
\family typewriter
--html
\family default
 at will.
\end_layout

\begin_layout Subsection
Internationalization
\end_layout

\begin_layout Standard
eLyXer is distributed along with a few translation files.
 They are automatically regenerated every time 
\family typewriter
make
\family default
 is run, and reside in the folder 
\family typewriter
po/
\family default
.
 Internationalization is done using GNU 
\family typewriter
gettext
\family default
, so every locale is identified by a two-letter code (such as 
\begin_inset Quotes eld
\end_inset

en
\begin_inset Quotes erd
\end_inset

 for English and 
\begin_inset Quotes eld
\end_inset

es
\begin_inset Quotes erd
\end_inset

 for Spanish).
 There are two kinds of files: the text 
\family typewriter
.po
\family default
 file (which can be found in 
\family typewriter
po/my.po
\family default
 for locale 
\begin_inset Quotes eld
\end_inset

my
\begin_inset Quotes erd
\end_inset

), and the binary 
\family typewriter
.mo
\family default
 file (found in 
\family typewriter
po/my/elyxer.po
\family default
).
\end_layout

\begin_layout Standard
For internationalization to work properly, Linux distributors should take
 all binary 
\family typewriter
.mo
\family default
 files and place them in the directory corresponding to locale files, which
 we will call 
\family typewriter
$localedir
\family default
.
 As 
\begin_inset CommandInset href
LatexCommand href
name "the Python gettext page"
target "http://docs.python.org/library/gettext.html"

\end_inset

 explains, this is distribution-dependent: for example on Debian 
\family typewriter
$localedir
\family default
 is 
\family typewriter
/usr/share/locale
\family default
, so for locale 
\begin_inset Quotes eld
\end_inset

es
\begin_inset Quotes erd
\end_inset

 the correct route would be
\end_layout

\begin_layout LyX-Code

\family typewriter
/usr/share/locale/es/LC_MESSAGES/elyxer.mo
\end_layout

\begin_layout Standard
Windows distributors on the other hand should place files in 
\family typewriter
%PYTHONHOME%
\backslash
share
\backslash
locale
\family default
, for example for locale 
\begin_inset Quotes eld
\end_inset

es
\begin_inset Quotes erd
\end_inset

 on a machine where Python is in 
\family typewriter
C:

\end_layout

\begin_layout Standard
To generate a new translation file (we will use 
\begin_inset Quotes eld
\end_inset

my
\begin_inset Quotes erd
\end_inset

 as an example locale here, corresponding to Burmese): you need to have
 the GNU 
\family typewriter
gettext
\family default
 package installed.
 Then go to the directory where elyxer.pot resides:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 cd src/conf
\end_layout

\begin_layout Standard
and generate a 
\family typewriter
.po
\family default
 file for your locale:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 msginit --output-file=my.po --locale=my
\end_layout

\begin_layout Standard
Then move the file to the 
\family typewriter
po/
\family default
 directory:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 mv my.po ../../po/
\end_layout

\begin_layout Standard
and start translating it to Burmese! Once you are done run make from the
 root directory:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 ./make
\end_layout

\begin_layout Standard
and it will generate the file 
\family typewriter
po/my/elyxer.mo
\family default
.
 Finally, place this file in
\end_layout

\begin_layout LyX-Code

\family typewriter
$localedir/my/LC_MESSAGES/elyxer.mo
\end_layout

\begin_layout Standard
and you are done.
\end_layout

\begin_layout Subsection
Math
\begin_inset CommandInset label
LatexCommand label
name "sub:Math"

\end_inset


\end_layout

\begin_layout Standard
Math equations are an important part of what takes LyX apart from other
 editors, since it supports the full LaTeX feature set -- that is, about
 everything under the sun.
 Unfortunately, math support is hard to get right.
 Many developers are focusing on MathML, but at the time of this writing
 (Q2 2010) support on some common browsers is still missing.
\end_layout

\begin_layout Standard
eLyXer follows its usual minimalistic approach and doesn't try to be everything
 to everybody -- instead, it supports out of the box a set of usual constructs
 (fraction, square root) and tries to simulate others (binomial, overbrace).
 See the 
\begin_inset CommandInset href
LatexCommand href
name "Math showcase"
target "math.html"

\end_inset

 for yourself and learn what eLyXer supports and what not.
\end_layout

\begin_layout Standard
For more sophisticated math equations there are a couple of advanced features.
\end_layout

\begin_layout Subsubsection*
jsMath
\end_layout

\begin_layout Standard
The first is to use 
\begin_inset CommandInset href
LatexCommand href
name "jsMath"
target "http://www.math.union.edu/~dpvc/jsMath/welcome.html"

\end_inset

, for which you have to run eLyXer with the option 
\family typewriter
--jsmath
\family default
:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 elyxer.py --jsmath jsMath/ math.lyx math-jsmath.html
\end_layout

\begin_layout Standard
It uses the given URL (in this case the relative URL 
\family typewriter
jsMath/
\family default
) to load the required JavaScript files and start rendering.
 Unfortunately, all JavaScript code has to be loaded from the same domain
 as the main document, so if you wish to use this method you will have to
 host jsMath on your site.
 See the 
\begin_inset CommandInset href
LatexCommand href
name "Math showcase (jsMath edition)"
target "math-jsmath.html"

\end_inset

 to see how jsMath improves (or deteriorates) the picture for you.
\end_layout

\begin_layout Subsubsection*
MathJax
\end_layout

\begin_layout Standard
Another possibility is to use 
\begin_inset CommandInset href
LatexCommand href
name "MathJax"
target "http://www.mathjax.org/"

\end_inset

, which is just as simple with the option 
\family typewriter
--mathjax
\family default
:
\end_layout

\begin_layout LyX-Code

\family typewriter
\color blue
$
\color inherit
 elyxer.py --mathjax MathJax/ math.lyx math-jsmath.html
\end_layout

\begin_layout Standard
This option also uses the given URL (now 
\family typewriter
MathJax/
\family default
) to load MathJax from and set it up.
 Although some code needs to be hosted on the same site as the pages, MathJax
 uses a feature called web-fonts which can be downloaded from a public server;
 this is quite easier to host.
 See the 
\begin_inset CommandInset href
LatexCommand href
name "Math showcase (MathJax edition)"
target "math-mathjax.html"

\end_inset

 to see how MathJax fares with eLyXer.
 Keep in mind that MathJax is still prerelease quality; it should improve
 greatly during 2010.
\end_layout

\begin_layout Subsubsection*
Client-side Rendering
\end_layout

\begin_layout Standard
Something to note is that both jsMath and MathJax are JavaScript libraries;
 all rendering is done client-side by the user's browser.
 This has quite a few advantages:
\end_layout

\begin_layout Itemize
Math processing on the server is quite light; equations are basically surrounded
 by a special tag and left in TeX form.
\end_layout

\begin_layout Itemize
For developers: integration of these libraries is very easy.
 It took just a few days to integrate both libraries with eLyXer.
\end_layout

\begin_layout Itemize
Both libraries (especially MathJax) are improving all the time thanks to
 the efforts of Davide P.
 Cervone and the rest of the developer team; eLyXer and its users reap the
 benefits readily.
\end_layout

\begin_layout Itemize
The client browser already knows its abilities, and can choose the rendering
 method it considers to be the best.
 MathJax can even choose between MathML and HTML+CSS 
\emph on
at page rendering time
\emph default
, showing MathML on fancier browsers and simpler HTML where it is not available.
\end_layout

\begin_layout Standard
It also brings some disadvantages:
\end_layout

\begin_layout Itemize
JavaScript code can only be loaded from the server originating the page.
 This means that you cannot host your pages e.g.
 at www.myserver.com and MathJax at www.mymathjaxserver.com.
\end_layout

\begin_layout Itemize
As a consequence, everyone publishing eLyXer pages converted with 
\family typewriter
--mathjax
\family default
 needs to also host the code for MathJax, and the same for jsMath.
 (Web fonts used in MathJax can at least be hosted elsewhere, so publishers
 do not need to also host the fonts package, but this hasn't still been
 used in eLyXer.)
\end_layout

\begin_layout Itemize
And of course it takes some time to render everything on the client, which
 can degrade the user experience on older machines.
\end_layout

\begin_layout Standard
Publishers should carefully consider pros and cons before deciding what
 to use.
\end_layout

\begin_layout Subsection
Footnotes
\begin_inset CommandInset label
LatexCommand label
name "sub:Footnotes"

\end_inset


\end_layout

\begin_layout Standard
Footnote generation is surprisingly hard to get right in an HTML document.
 eLyXer has a fairly complete set of command line options to customize how
 footnotes are generated.
 Here we will use the aggregated option 
\family typewriter
--footnotes "options"
\family default
 which can be used to specify any combination, but they can be turned on
 independently using 
\family typewriter
--\SpecialChar \ldots{}
foot
\family default
.
 For instance: 
\family typewriter
--footnotes number,margin
\family default
 is equivalent to 
\family typewriter
--numberfoot --marginfoot
\family default
.
\end_layout

\begin_layout Subsubsection*
Markers
\end_layout

\begin_layout Standard
The footnote is attached to a point of the text (the 
\emph on
referring
\emph default
 text) which is usually marked by a bit of text.
 The default behavior for the marker is to use a superscript letter surrounded
 by square brackets, in blue: 
\color blue

\begin_inset Formula $^{\text{[A]}}$
\end_inset


\color inherit
.
 The text can be changed to aligned text with 
\family typewriter
--footnotes align
\family default
: 
\color blue
[A]
\color inherit
, so markers are not mistaken with other superscript constructs such as
 exponents (like 
\begin_inset Formula $e^{a}$
\end_inset

).
\end_layout

\begin_layout Standard
Markers can also be converted to numbers using 
\family typewriter
--footnotes number
\family default
: 
\color blue

\begin_inset Formula $^{\text{[1]}}$
\end_inset

.

\color inherit
 Or, they can be switched over to symbols using 
\family typewriter
--footnotes symbol
\family default
: 
\color blue

\begin_inset Formula $^{\text{⁎}}$
\end_inset


\color inherit
.
 Available symbols are rotated from this sequence: * ** † ‡ § §§ ¶ ¶¶ #
 ##.
 All options can be combined.
 For instance, symbol markers look best when shown aligned; 
\family typewriter
--footnotes align,symbol
\family default
 will show aligned symbolic markers such as 
\color blue
*
\color inherit
 or 
\color blue
†
\color inherit
.
\end_layout

\begin_layout Subsubsection*
Position
\end_layout

\begin_layout Standard
Footnotes are supposed to appear at the foot of the page, but that is not
 always possible or practical in web pages.
 Huge pages make scrolling up and down quite uncomfortable, and remove the
 immediacy of having the note in the same page as the referring text.
\end_layout

\begin_layout Standard
There are a few alternatives: use the margin, show hovering text, or link
 to the note at the bottom of the page.
 eLyXer can use all three.
 
\family typewriter
--footnotes margin
\family default
 will place the notes at the margin, just as margin notes but with the addition
 of the footnote marker.
 While 
\family typewriter
--footnotes hover
\family default
 will show hovering text when the mouse is placed on the marker; this is
 the default behavior.
 Note that hovering notes are converted into margin notes when printing.
\end_layout

\begin_layout Standard
When footnotes are shown at the end of the page with 
\family typewriter
--footnotes end
\family default
, footnote markers turn into links.
 The actual footnote at the end then contains a link back to the marker.
\end_layout

\begin_layout Standard
The most interesting part is that these three options can be combined at
 will: 
\family typewriter
--footnotes margin,hover,end
\family default
 will show footnotes at the three possible locations.
 The most practical combination is probably 
\family typewriter
--footnotes hover,end
\family default
, which will show notes as hovering text and also at the end of the page.
 Note however that in this case notes will be printed twice (at the margin
 instead of hovering and at the end).
\end_layout

\begin_layout Section
Work in Progress
\end_layout

\begin_layout Standard
As you can see eLyXer is a mature and tried package, but it has some rough
 edges.
\end_layout

\begin_layout Subsection
Known Issues
\end_layout

\begin_layout Standard
The following issues (including bugs and missing features) are acknowledged.
 Some of them should be solved soon; others may take longer.
\end_layout

\begin_layout Enumerate
On Mac OS X the output of a message with Unicode characters may cause an
 error.
 Workaround: run 
\family typewriter
elyxer.py
\family default
 with the 
\family typewriter
--quiet
\family default
 option.
\end_layout

\begin_layout Enumerate
Some phonetic alphabet symbols are not well supported -- if generated with
 LyX they only appear in a different color: 
\begin_inset Formula $\text{\textipa{[sample]}}$
\end_inset

.
 
\begin_inset Note Note

\begin_layout Plain Layout
This happens only in the HTML file converted with eLyXer, not from within
 LyX.
\end_layout

\end_inset


\begin_inset Note Comment

\begin_layout Plain Layout
By the way, the previous note (and this one) should not appear on the HTML.
\end_layout

\end_inset


\end_layout

\begin_layout Enumerate
Multi-column layouts are lost.
 This one is almost impossible to get right in CSS, so there are no plans
 to even try.
\end_layout

\begin_layout Enumerate
Many BibTeX styles are missing.
 (They are quite trivial to add though.)
\end_layout

\begin_layout Enumerate
ERT (bare TeX code) is ignored.
\end_layout

\begin_layout Enumerate
Many AMS environments (like 
\family typewriter
alignat
\family default
, 
\family typewriter
gather
\family default
\SpecialChar \ldots{}
) are not working or look strange -- some non-AMS environments too.
\end_layout

\begin_layout Enumerate
Images are never scaled above their nominal resolution.
 This is seldom needed if at all, so there are no plans to change it; if
 people really need the feature just let the author know so it can be added
 as an option.
\end_layout

\begin_layout Subsection
Wish List
\begin_inset CommandInset label
LatexCommand label
name "sub:Wish-List"

\end_inset


\end_layout

\begin_layout Standard
The following features have been requested by users; specific people are
 referenced by a couple of initials so they can recognize themselves while
 keeping some anonymity.
 (If you prefer that your initials do not to appear here at all just let
 me know.)
\end_layout

\begin_layout Standard
Queued features will be added at the next big release -- the priority for
 each feature will be set by the number of users requesting it and date
 requested.
 Pending features need some assessment.
 Those marked as too complex have been evaluated as requiring too much work,
 but the decision might be reversed if there are enough people interested
 or a simple way to implement them is found.
 Once done, features are marked with the first release where they appear.

\end_layout

\begin_layout Standard
The EPUB management package 
\begin_inset CommandInset href
LatexCommand href
name "calibre"
target "http://calibre-ebook.com/user_manual/conversion.html"

\end_inset

 does not output valid EPUB documents when converted from eLyXer HTML files,
 at least according to the 
\begin_inset CommandInset href
LatexCommand href
name "Threepress validator"
target "http://threepress.org/document/epub-validate"

\end_inset

.
\end_layout

\begin_layout Standard
This is a complex feature request; calibre does minimal formatting in its
 EPUB conversion, so making it generate valid EPUB documents requires changing
 deeply how eLyXer outputs XHTML.
 Lots of help would be needed to get this working.
\end_layout

\begin_layout Standard
This feature would be most welcome from the part of the author.
 Unfortunately, Firefox alone from the major browsers refuses to render
 
\family typewriter

\family default
 tags correctly for SVG.
 According to 
\begin_inset CommandInset href
LatexCommand href
name "bug #276431"
target "https://bugzilla.mozilla.org/show_bug.cgi?id=276431"

\end_inset

, this was fixed on 2010-09-08, so the next version should do the right
 thing; at that point this feature will be queued for inclusion.

\begin_layout Subsubsection*
More controls for image conversion
\begin_inset CommandInset label
LatexCommand label
name "sub:More-controls-for"

\end_inset


\end_layout

\begin_layout Standard
eLyXer uses ImageMagick to convert images.
 Some images (in EPS format, for example) do have blank borders, or they
 come in varied sizes.
 It would be nice to remove blank borders and have some kind of unified
 resolution in the conversion, which would be passed to ImageMagick.
\end_layout

\begin_layout Standard
As of 1.1.0, the improvements include using 
\family typewriter
ps:use-cropbox=true
\family default
 in ImageMagick for PostScript and EPS images.
 Unified resolution has not been added as it might collide with picture
 density, but suggestions are welcome.

]A mixed solution for CSS styles:
\end_layout

\begin_layout Enumerate
The essential minimum css for math formatting (a compacted version of a
 
\family typewriter
math.css
\family default
 subset) included directly inside HTML head.
\end_layout

\begin_layout Enumerate
Then a call to download the on-line full CSS, that can repeat the minimum
 already included 
\family typewriter
math.css
\family default
 (from item 1) plus some other styles.
 The default can be changed by 
\family typewriter
--css
\family default
 command line option.
\end_layout

\begin_layout Enumerate
A new option (
\family typewriter
--addcss
\family default
) to add another CSS defined by the user.
 For example, to only redefine some styles from the default, etc.
\end_layout

\begin_layout Standard
The styles should be included in that order (using the "cascading" property).
 Item 1 is fixed in every HTML file.
 Item 2 is always added and by default pointing to the eLyXer on-line css,
 but it can be changed by option 
\family typewriter
--css
\family default
 to another url or file.
 Item 3 is optional and its url would be added after the other two items,
 only if the 
\family typewriter
--addcss
\family default
 option was used in conversion.

\end_layout

\begin_layout Standard
As of 1.1.1, an option

 has been added which allows embedding one or more custom CSS files into

\family default
 can be repeated as many times as desired to use several CSS files.

\begin_layout Subsection
Extending eLyXer
\end_layout

\begin_layout Standard
eLyXer should now support most LyX features; but sometimes it will ignore
 a command, sometimes it will signal it, and it might even refuse to work
 with certain documents.
 What can you do if eLyXer does not work with your LyX file? Worry not!
 Its flexible approach to processing allows anyone to write support for
 the missing commands.
\end_layout

\begin_layout Standard
eLyXer is written in Python so that it does not need to be compiled; its
 code is interpreted on the fly.
 See the accompanying 
\begin_inset CommandInset href
LatexCommand href
name "developer guide"
target "devguide.html"

\end_inset

 to learn how to extend eLyXer for your own purposes.
 If you know how to program in Python it should not be difficult to support
 other LyX features.
 If you don't your best bet is to ask the author.
\end_layout

\begin_layout Section
FAQ
\end_layout

\begin_layout Description
Q: What versions of LyX are supported?
\end_layout

\begin_layout Description
A: The tool is slowly improving; it now should work with LyX versions 1.5.5
 to 1.6.5.
 It has been tested on Linux, Mac OS X and Windows.
\end_layout

\begin_layout Description
Q: There are indeed 
\emph on
a ton
\emph default
 of similar projects over the web.
 Why add another one?
\end_layout

\begin_layout Description
A: The four tools supported by LyX (tex4ht, hevea, tth and latex2html) gave
 inferior results a couple of years ago, and were quite inflexible.
 The author found the need for a good converter, while at the same time
 acknowledging the difficulty of the problem.
\end_layout

\begin_layout Description
Q: Speaking of that: why build a LyX to HTML converter, instead of a more
 generic LaTeX to HTML converter?
\end_layout

\begin_layout Description
A: The problem space is quite simplified, and therefore progress is much
 faster.
 To make it even easier eLyXer has historically centered on the subset of
 LyX functionality that is useful to most LyX users, leaving the rest for
 a later stage.
 Nowadays eLyXer aims to support the full LyX feature set.
\end_layout

\begin_layout Description
Q: What can we expect from the tool in the future?
\end_layout

\begin_layout Description
A: eLyXer should fulfill the needs of 99% of LyX users in the short term.
 It has also learned a couple of tricks of its own such as page segmenting.
 Eventually it could be distributed along with LyX as part of the standard
 installer.
\end_layout

\begin_layout Description
Q: Why did you leave out my favorite feature 
\emph on
<insert random LyX command here>
\emph default
?
\end_layout

\begin_layout Description
A: In short, because nobody asked for it.
 Every feature which has been requested (either to me personally or to the
 list) has been tended to, unless it was too far out or I forgot about it.
 At this point of development every missing LyX feature will be considered
 a high priority item for the next version, if at all possible to implement.
\end_layout

\begin_layout Description
Q: My document changed its appearance without my intervention.
 Was it black magic, elves or what?
\end_layout

\begin_layout Description
A: It probably uses the online CSS file, which is regularly updated.
 See section 
\begin_inset CommandInset ref
LatexCommand ref
reference "sub:CSS"

\end_inset

 for details.
\end_layout

\begin_layout Description
Q: Why use an online CSS, instead of placing the CSS file in the same directory
 as the converted file?
\end_layout

\begin_layout Description
A: There were pros and cons.
 An online CSS resource allowed me to update it for everyone at the same
 time, but might make it more difficult for people without an internet connectio
n; local CSS files are more flexible but can also be confusing to novice
 users.
 In the end the online solution was preferred, with the 
\family typewriter
--css
\family default
 option as a fallback.
