<?php /* bibtexbrowser: publication lists with bibtex and PHP
<!-- __ID__ -->
bibtexbrowser is a PHP script that creates publication lists from Bibtex files. For feature requests, bug reports, or patch proposals, [[http://www.monperrus.net/martin/|please drop me an email ]] or comment this page.
[[#Download|Download section]]
=====Major features=====
* **(11/2009)** Optimize your presence on Google Scholar: bibtexbrowser generates [[http://www.monperrus.net/martin/accurate+bibliographic+metadata+and+google+scholar|Google Scholar metadata]]
* **(11/2009)** More and more academics use bibliographic software like [[http://www.zotero.org/|Zotero]] or [[http://www.mendeley.com/|Mendeley]]. bibtexbrowser generates [[http://ocoins.info/|COinS]] for automatic import of bibliographic entries.
* **(10/2009)** People can subscribe to the RSS publication feed of an individual or a group so as to being kept up-to-date: bibtexbrowser generates RSS feeds for all queries (simply add &#38;rss at the end of the URL)! [[http://www.monperrus.net/martin/bibtexbrowser.php?bib=monperrus.bib&amp;all&amp;rss|demo]]
* **(02/2009)** bibtexbrowser can display all entries for an author with an academic style (i.e book, articles, conference, workshop): [[http://www.monperrus.net/martin/bibtexbrowser.php?bib=metrics.bib&amp;academic=Ducasse|demo]]
* **(05/2008)**: bibtexbrowser can be used to embed a publication list into another page: [[http://www.monperrus.net/martin/|demo]]
* **(04/2007)**: bibtexbrowser is easy to install: just a single file.
=====Other features=====
* **(01/2010)** bibtexbrowser can handle user-defined bibliographic styles
* **(10/2009)** bibtexbrowser is able to generate a bibtex file containing only the selected entries (simply add &#38;astext at the end of the link)
* **(10/2009)** bibtexbrowser is now independent of the configuration of register_globals
* **(01/2009)** bibtexbrowser allows multi criteria search, e.g. [[http://www.monperrus.net/martin/bibtexbrowser.php?bib=metrics.bib&amp;type=inproceedings&amp;year=2004|demo]]
* bibtexbrowser replaces constants defined in @STRING
* bibtexbrowser is very fast because it keeps a compiled version of the bibtex file (PHP object serialized)
* bibtexbrowser is compatible with PHP 4.x and PHP 5.x
* bibtexbrowser can display the menu and all entries without filtering from the file name passed as parameter [[http://www.monperrus.net/martin/bibtexbrowser.php?bib=metrics.bib|demo]]
* bibtexbrowser can display all entries out of a bibtex file [[http://www.monperrus.net/martin/bibtexbrowser.php?bib=metrics.bib&amp;all|demo]]
* bibtexbrowser can display all entries for a given year [[http://www.monperrus.net/martin/bibtexbrowser.php?bib=metrics.bib&amp;year=2004|demo]]
* bibtexbrowser can display a single bibtex entry [[http://www.monperrus.net/martin/bibtexbrowser.php?bib=metrics.bib&amp;key=monperrus08d|demo]]
* bibtexbrowser can display found entries with a search word (it can be in any bib field) [[http://www.monperrus.net/martin/bibtexbrowser.php?bib=metrics.bib&amp;search=ocl|demo]]
* bibtexbrowser can display all entries with a bib keyword
* bibtexbrowser outputs valid XHTML 1.0 Transitional
* bibtexbrowser can display all entries for an author [[http://www.monperrus.net/martin/bibtexbrowser.php?bib=metrics.bib&amp;author=Barbara+A.+Kitchenham|demo]]
* bibtexbrowser can be used with different encodings (change the default iso-8859-1 encoding if your bib file is in utf-8 ''define('ENCODING','utf-8')'' )

<a href="bibtexbrowser-screenshot.png"><img height="500" src="bibtexbrowser-screenshot.png" alt="bibtexbrowser screenshot"/></a>
=====How to create standalone publication lists=====
1) Create a bib file with the publication records (e.g. csgroup2008.bib)
* Use the link ''bibtexbrowser.php?bib=csgroup2008.bib'' (frameset based view)
* Use the link ''bibtexbrowser.php?bib=csgroup2008.bib&amp;all'' (pub list sorted by year)
* Use the link ''bibtexbrowser.php?bib=csgroup2008.bib&amp;all&amp;academic'' (pub list sorted by publication type, then by year)
=====How to include your publication list in your home page=====
<table border="1">
<tr><th></th><th>Sorted by year </th><th>Sorted by publication type</th></tr>
<tr><td>For a group/team/lab</td>
<td>
&#60;?php
$_GET&#91;'bib'&#93;='csgroup2008.bib';
$_GET&#91;'all'&#93;=1;
include( 'bibtexbrowser.php' );
?>
</td>
<td>
&#60;?php
$_GET&#91;'bib'&#93;='csgroup2008.bib';
$_GET&#91;'all'&#93;=true;
$_GET&#91;'academic'&#93;=true;
include( 'bibtexbrowser.php' );
?>
</td>
</tr><!-- end group -->
<tr><td>For an individual</td>
<td>
&#60;?php
$_GET&#91;'bib'&#93;='mybib.bib';
$_GET&#91;'author'&#93;='Martin Monperrus';
include( 'bibtexbrowser.php' );
?>
</td>
<td>
&#60;?php
$_GET&#91;'bib'&#93;='mybib.bib';
$_GET&#91;'academic'&#93;='Martin Monperrus';
include( 'bibtexbrowser.php' );
?>
</td>
</tr><!-- end individual -->
</table>
And tailor it with a CSS style, for example:
&#60;style>
.date { background-color: blue; }
.rheader { font-size: large }
.bibref { padding:3px; padding-left:15px; vertical-align:top;}
.bibtitle { font-weight:bold; }
.bibbooktitle { font-style:italic; }
&#60;/style>
=====How to add links to the slides of a conference/workshop paper?=====
You can simply fill the ''comment'' field of the bib entry with an HTML link:
<code>
@inproceedings{foo,
author="Jean Dupont",
title="Bibtexbrowser",
year=2009,
booktitle="Proceedings of the BIB conference",
comment={&lt;a href="myslides.pdf">slides&lt;/a>}
}
</code>
=====How to tailor bibtexbrowser?=====
====By modiyfing the CSS====
If bibtexbrowser.css exists, it will be used, otherwise bibtexbrowser uses the embedded CSS style (search for "embedded CSS", ~line 2060).
====By modiyfing the configuration parameters====
All configuration parameters are of the form ''define("PARAMETER_NAME","PARAMER_VALUE")'' at the beginning of the script. You can modify them by creating a file named "bibtexbrowser.local.php" containing the modified value. For instance:
''@define("ENCODING","utf-8");'' if your bibtex file is utf-8 encoded
<a name="modify-bibstyle"/>
====By modifying the bibliography style ====
The bibliography style is encapsulated in a function. If you want to modify the bibliography style, you can copy the default style ([[bibtexbrowser-style-default.php.txt|source]]) in a new file, say ''bibtexbrowser-yourstyle.php'', and rename the function ''DefaultBibliographyStyle'' in say ''MyFancyBibliographyStyle''.
Then, add in the file ''bibtexbrowser.local.php'':
<code>
include( 'bibtexbrowser-yourstyle.php' );
define('BIBLIOGRAPHYSTYLE','MyFancyBibliographyStyle');
</code>
[[http://www.monperrus.net/martin/bibtexbrowser-style-janos.php.txt|János Tapolcai contributed with this style, which looks like IEEE references]].

=====Related_tools=====
[[http://www.monperrus.net/martin/bibtex2latex|bibtex2latex is a layer on top of bibtexbrowser that generates publication lists in latex.]]
Old-fashioned:
[[http://nxg.me.uk/dist/bibhtml/|bibhtml]], [[http://www.litech.org/~wkiri/bib2html/|bib2html]], [[http://ilab.usc.edu/bibTOhtml/|bibtohtml]], [[http://people.csail.mit.edu/rahimi/bibtex/|bibtextohtml]], [[http://www.lri.fr/~filliatr/bibtex2html/|bibtex2html]], [[http://people.csail.mit.edu/mernst/software/bibtex2web.html |bibtex2web]], [[http://strategoxt.org/Stratego/BibtexTools|stratego bibtex module]]
Unlike them, **bibtexbrowser is dynamic**.i.e.; generates the HTML pages on the fly.
Thus, you do not need to regenerate the static HTML files each time the bib file is changed.
Furthermore you can search any string in it.
Heavyweight:
[[http://www.rennes.supelec.fr/ren/perso/etotel/PhpBibtexDbMng/|PHP BibTeX Database Manager]], [[http://gforge.inria.fr/projects/bibadmin/|bibadmin]], [[http://artis.imag.fr/Software/Basilic/|basilic]], [[http://phpbibman.sourceforge.net/|phpbibman]], [[http://www.aigaion.nl/|aigaion]], [[http://www.refbase.net/|refbase]], [[http://wikindx.sourceforge.net/|wikindx]], [[http://refdb.sourceforge.net/|refdb]]
Unlike them, **bibtexbrowser does not need a MySQL database**
Main competitors:
[[http://code.google.com/p/simplybibtex/|SimplyBibtex]] has the same spirit and makes different architectural and presentation choices
=> **bibtexbrowser is much more lightweight** (just one file!).
[[http://www.cs.toronto.edu/~fritz/bibbase/|BibBase]] is a nice and very similar script, but written in Perl
=> **bibtexbrowser does not require a CGI/Perl compliant webserver** .
Misc:

/** Release 2009-01-05
* Added support for new bibliographic styles (users just have to create a function and change a configuration parameter, see documentation)
* Packaged the IEEE-like bibliographic style of János Tapolcai (many thanks János), see http://www.monperrus.net/martin/bibtexbrowser-style-janos.php.txt
* Added support for external CSS (if bibtexbrowser.css exists, it is used instead of the embedded one)
* Added support for local configuration parameters in bibtexbrowser.local.php
* Bug in RSS fixed (handling of &)
* Bug found by Nelson fixed (the link to all bib entries)

Congratulations! bibtexbrowser is correctly installed!<br/>
Now you have to pass the name of the bibtex file as parameter (e.g. bibtexbrowser.php?bib=mybib.php)<br/>
You may browse:<br/>
<?php
foreach (glob("*.bib") as $bibfile) {
$url="?bib=".$bibfile; echo '<a href="'.$url.'">'.$bibfile.'</a><br/>';
}
exit;
}
if (!file_exists($_GET[Q_FILE])) {
// to automate dectection of faulty links with tools such as webcheck
header('HTTP/1.1 404 Not found');
die('<b>the bib file '.$_GET[Q_FILE].' does not exist !</b>');
}
// PHP version
// 20091010: bibtexbrowser is again PHP4 compatible :-)
/*if (ereg('^4',phpversion())) {
?>
You are using PHP v<?php echo phpversion();?><br/>
<b>bibtexbrowser requires a version of PHP >= 5 (PHP5)</b><br/>
QuickFix: you can try to add in .htaccess of the containing directory:
<code>
SetEnv PHP_VER 5
</code>
<?php
exit;
}*/
// save bandwidth and server cpu
// (imagine the number of requests from search engine bots...)
if (isset($_SERVER['HTTP_IF_MODIFIED_SINCE']) && (strtotime($_SERVER['HTTP_IF_MODIFIED_SINCE'])>filemtime($_GET[Q_FILE]))) {
header("HTTP/1.1 304 Not Modified");
exit;
}
// for sake of performance, once the bibtex file is parsed
// we try to save a "compiled" in a txt file
$compiledbib = $_GET[Q_FILE].'.txt';
$parse=true;
// do we have a compiled version ?
if (is_file($compiledbib) && is_readable($compiledbib)) {
// is it up to date ? wrt to the bib file and the script
// then upgrading with a new version of bibtexbrowser triggers a new compilation of the bib file
if (filemtime($_GET[Q_FILE])<filemtime($compiledbib) && filemtime(__FILE__)<filemtime($compiledbib)) {
$_GET[Q_DB] = unserialize(file_get_contents($compiledbib));

}
