<h1>Updated filters for Recoll</h1>
|
||||
|
||||
<p>The following describe new and updated filters, which will be
|
||||
part of the next release, but can be installed on the current
|
||||
release if you need them.</p>
|
||||
|
||||
<p>For updated filters, you just need to copy the script to the
|
||||
filters directory which may be typically either <span
|
||||
class="filename">/usr/share/recoll/filters</span>, or <span
|
||||
class="filename">/usr/local/share/recoll/filters</span>.</p>
|
||||
|
||||
<p>For new filters, you'll need to copy the script file as
|
||||
above, possibly install the supporting application, and usually
|
||||
edit the
|
||||
<span class="filename">mimemap</span>,
|
||||
<span class="filename">mimeview</span> and
|
||||
<span class="filename">mimeconf</span> files, either in the
|
||||
shared directory
|
||||
(<span class="filename">
|
||||
/usr[/local]/share/recoll/examples</span>), or
|
||||
in your personal configuration directory
|
||||
(<span class="filename">$HOME/.recoll</span> or
|
||||
<span class="filename">$RECOLL_CONFDIR</span>).</p>
|
||||
|
||||
<p>Alternatively, you can replace your 1.[8,9,10] system files with
|
||||
these updated and complete versions:
|
||||
<a href="mimemap">mimemap</a>
|
||||
<a href="mimeconf">mimeconf</a>
|
||||
<a href="mimeview">mimeview</a> </p>
|
||||
|
||||
<p>Notes:</p>
|
||||
<blockquote>
|
||||
<p>All filters are up to date in Recoll 1.10.5</p>
|
||||
|
||||
<p>Recoll 1.10.0: only <span class="filename">rclsvg</span> for
|
||||
Scalable Vector Graphic files is missing.</p>
|
||||
|
||||
<p>Recoll 1.9: all filters are up to date in the release,
|
||||
except the <span class="filename">rclimg</span> image
|
||||
filter and <span class="filename">rcltex</span>TeX filter.</p>
|
||||
|
||||
<p>Recoll 1.8: The image, <b>kword</b>,
|
||||
<b>abiword</b> and <b>wordperfect</b> can be installed in
|
||||
addition.</p>
|
||||
</blockquote>
|
||||
|
||||
<h2>Open XML Office formats</h2>
|
||||
|
||||
<p>Filter: <a href="rclopxml">rclopxml</a>. </p>
|
||||
<p>This needs <span class="command">xsltproc</span> to be
|
||||
installed (if you run a decently recent Linux, this is
|
||||
probably on your system already). </p>
|
||||
|
||||
<p>The filters are certainly not perfect, but extract a good
|
||||
part of the text, which is probably better than nothing.</p>
|
||||
|
||||
<p>There are quite a few added lines in the configuration
|
||||
files, just fetch the new ones:
|
||||
<a href="mimemap">mimemap</a>
|
||||
<a href="mimeconf">mimeconf</a>
|
||||
<a href="mimeview">mimeview</a> </p>
|
||||
|
||||
|
||||
<h2>Scalable Vector Graphics filter</h2>
|
||||
|
||||
<p>A new filter for <b>SVG</b> files:
|
||||
<a href="rclsvg">rclsvg</a>.
|
||||
You'll have to add the following lines in the configuration
|
||||
files:</p>
|
||||
|
||||
<p>In <span class="filename">mimemap</span>: </p>
|
||||
<pre>.svg = image/svg+xml
|
||||
</pre>
|
||||
<p>In <span class="filename">mimeconf</span>, [index] section: </p>
|
||||
<pre>image/svg+xml = exec rclsvg</pre>
|
||||
<p><span class="filename">mimeconf</span>, [icons] section:</p>
|
||||
<pre>image/svg+xml = drawing</pre>
|
||||
<p><span class="filename">mimeconf</span>, [categories] section, also add
|
||||
<tt>image/svg+xml</tt> to the <tt>other</tt> list.</p>
|
||||
|
||||
<p>The filter is based on <span class="command">sed</span>, so
|
||||
you don't need to install any external application.</p>
|
||||
|
||||
<p>In
|
||||
<span class="filename">mimeview</span>, or the <em>[view]</em>
|
||||
section of
|
||||
<span class="filename">mimeconf</span> for older recoll versions: </p>
|
||||
<pre> image/svg+xml = inkview %f</pre>
|
||||
<p>(Or substitute your favorite editor).</p>
|
||||
|
||||
|
||||
|
||||
<h2>TeX filter</h2>
|
||||
|
||||
<p>A new filter for <b>TeX</b> files:
|
||||
<a href="rcltex">rcltex</a>.
|
||||
You'll have to add the following lines in the configuration
|
||||
files:</p>
|
||||
|
||||
<p>In <span class="filename">mimemap</span>: </p>
|
||||
<pre>.tex = application/x-tex
|
||||
</pre>
|
||||
<p>In <span class="filename">mimeconf</span>, [index] section: </p>
|
||||
<pre> application/x-tex = exec rcltex</pre>
|
||||
<p>mimeconf, [icons] section:</p>
|
||||
<pre>application/x-tex = wordprocessing</pre>
|
||||
<p>mimeconf, [categories] section, also add
|
||||
application/x-tex to the <tt>texts</tt> list.</p>
|
||||
|
||||
<p>This filter uses either <span class="command">untex</span>
|
||||
or <a
|
||||
"href=http://www.cs.purdue.edu/homes/trinkle/detex/">detex</a>
|
||||
if the command is available. . A copy of the
|
||||
source code for untex is stored <a "href=../untex/untex-1.3.jf.tar.gz">
|
||||
here</a></p>
|
||||
|
||||
<p>In
|
||||
<span class="filename">mimeview</span>, or the <em>[view]</em>
|
||||
section of
|
||||
<span class="filename">mimeconf</span> for older recoll versions: </p>
|
||||
<pre> application/x-tex = gnuclient -q %f</pre>
|
||||
<p>(Or substitute your favorite editor).</p>
|
||||
|
||||
|
||||
<h2>A filter for image tags</h2>
|
||||
|
||||
<p>A new filter for extracting tags from image and picture files:
|
||||
<a href="rclimg">rclimg</a>, by Cedric Scott. It is based on
|
||||
the <b>Exiftool</b> Perl application and library.
|
||||
You'll have to add the following lines in the configuration
|
||||
files:</p>
|
||||
|
||||
<p>In <span class="filename">mimemap</span>: </p>
|
||||
<pre>.jpeg = image/jpeg
|
||||
.gif = image/gif
|
||||
.tiff = image/tiff
|
||||
.tif = image/tiff
|
||||
</pre>
|
||||
<p>In <span class="filename">mimeconf</span>, [index] section: </p>
|
||||
<pre>image/gif = exec rclimg
|
||||
image/jpeg = exec rclimg
|
||||
image/png = exec rclimg
|
||||
image/tiff = exec rclimg
|
||||
</pre>
|
||||
<p>And remove the <tt>image/jpeg = exec rcljpeg</tt> line.</p>
|
||||
|
||||
<p>Exiftool supports many other image formats, just enter any
|
||||
additional ones like above.</p>
|
||||
|
||||
<h2>Wordperfect filter</h2>
|
||||
|
||||
<p>A new filter for <b>Wordperfect</b> files:
|
||||
<a href="rclwpd">rclwpd</a>.
|
||||
You'll have to add the following lines in the configuration
|
||||
files:</p>
|
||||
|
||||
<p>In <span class="filename">mimemap</span>: </p>
|
||||
<pre>.wpd = application/vnd.wordperfect
|
||||
</pre>
|
||||
<p>In <span class="filename">mimeconf</span>, [index] section: </p>
|
||||
<pre> application/vnd.wordperfect = exec rclwpd</pre>
|
||||
<p>mimeconf, [icons] section:</p>
|
||||
<pre>application/vnd.wordperfect = wordprocessing</pre>
|
||||
<p>mimeconf, [categories] section, also add
|
||||
application/vnd.wordperfect to the <tt>texts</tt> list.</p>
|
||||
|
||||
<p>In
|
||||
<span class="filename">mimeview</span>, or the <em>[view]</em>
|
||||
section of
|
||||
<span class="filename">mimeconf</span> for older recoll versions: </p>
|
||||
<pre> application/vnd.wordperfect = openoffice %f</pre>
|
||||
|
||||
<h2>Abiword filter</h2>
|
||||
|
||||
<p>A new filter for <a href="http://www.abisource.com/">
|
||||
abiword</a> files: <a href="rclabw">
|
||||
rclabw</a>.
|
||||
You'll have to add the following lines in the configuration
|
||||
files:</p>
|
||||
|
||||
<p>In <span class="filename">mimemap</span>: </p>
|
||||
<pre> .abw = application/x-abiword</pre>
|
||||
|
||||
<p>In <span class="filename">mimeconf</span>: </p>
|
||||
<pre> application/x-abiword = exec rclabw</pre>
|
||||
|
||||
<p>In
|
||||
<span class="filename">mimeview</span>, or the <em>[view]</em>
|
||||
section of
|
||||
<span class="filename">mimeconf</span> for older recoll versions: </p>
|
||||
<pre> application/x-abiword = abiword %f</pre>
|
||||
|
||||
<h2>Kword filter</h2>
|
||||
|
||||
<p>A new filter for <a href="http://www.kde.org/whatiskde/koffice.php/">
|
||||
kword</a> files: <a href="rclkwd">
|
||||
rclkwd</a>.
|
||||
You'll have to add the following lines in the configuration
|
||||
files:</p>
|
||||
|
||||
<p>In <span class="filename">mimemap</span>: </p>
|
||||
<pre> .kwd = application/x-kword</pre>
|
||||
<p>In <span class="filename">mimeconf</span>: </p>
|
||||
<pre> application/x-kword = exec rclkwd</pre>
|
||||
<p>In
|
||||
<span class="filename">mimeview</span>, or the <em>[view]</em>
|
||||
section of
|
||||
<span class="filename">mimeconf</span> for older recoll versions: </p>
|
||||
<pre> application/x-kword = kword %f</pre>
|
||||
|
||||
|
||||
<h2>Openoffice filter</h2>
|
||||
<p>The filter script for all releases up and including 1.7.5 had
|
||||
a bug on Debian and Ubuntu systems. You can download the <a
|
||||
href="rclsoff">corrected script</a>.</p>
|
||||
|
||||
<h2>Scribus filter</h2>
|
||||
|
||||
<p>A new filter for <a href="http://www.scribus.net/">
|
||||
Scribus</a> files: <a href="rclscribus">
|
||||
rclscribus</a>. This is only for the newer
|
||||
<em>.sla</em> files. I am willing to add support for the older
|
||||
<em>.scd</em> format if someone sends me a sample... You'll
|
||||
have to add the following lines in the configuration files:</p>
|
||||
|
||||
<p>In <span class="filename">mimemap</span>: </p>
|
||||
<pre> .sla = application/x-scribus</pre>
|
||||
<p>In <span class="filename">mimeconf</span>: </p>
|
||||
<pre> application/x-scribus = exec rclscribus</pre>
|
||||
<p>In
|
||||
<span class="filename">mimeview</span>, or the <em>[view]</em>
|
||||
section of
|
||||
<span class="filename">mimeconf</span> for older recoll versions: </p>
|
||||
<pre> application/x-scribus = scribus %f</pre>
|
||||
|
||||
<p>Do *not* add entries for <em>.sla.gz</em>, the normal recoll
|
||||
decompression process will handle them (hopefully...).</p>
|
||||
|
||||
|
||||
<h2>Lyx filter</h2>
|
||||
|
||||
<p>A new filter for <a href="http://www.lyx.or/">
|
||||
Lyx</a> files: <a href="rcllyx">rcllyx</a>.
|
||||
This probably has quite a few issues with character encoding,
|
||||
but it's also probably better than handling lyx documents as
|
||||
text files.</p>
|
||||
|
||||
<p>In <span class="filename">mimemap</span>: </p>
|
||||
<pre> .lyx = application/x-lyx</pre>
|
||||
<p>In <span class="filename">mimeconf</span>: </p>
|
||||
<pre> application/x-lyx = exec rcllyx</pre>
|
||||
<p>In
|
||||
<span class="filename">mimeview</span>, or the <em>[view]</em>
|
||||
section of
|
||||
<span class="filename">mimeconf</span> for older recoll versions: </p>
|
||||
<pre> application/x-lyx = lyx %f</pre>
