<p style="color: grey"> Python recipe 580727 by <a href="/recipes/users/4173351/">Vasudev Ram</a> (<a href="/recipes/tags/conversion/">conversion</a>, <a href="/recipes/tags/files/">files</a>, <a href="/recipes/tags/globbing/">globbing</a>, <a href="/recipes/tags/patterns/">patterns</a>, <a href="/recipes/tags/pdf/">pdf</a>, <a href="/recipes/tags/pdfwriter/">pdfwriter</a>, <a href="/recipes/tags/pdf_generation/">pdf_generation</a>, <a href="/recipes/tags/text_processing/">text_processing</a>, <a href="/recipes/tags/wildcard/">wildcard</a>, <a href="/recipes/tags/xtopdf/">xtopdf</a>). </p> <p>This recipe shows how to convert all text files matching a filename wildcard to PDF, using the xtopdf PDF creation toolkit. For example, if you specify report<em>.txt as the wildcard, all files in the current directory that match report</em>.txt, will be converted to PDF, each in a separate PDF file. The original text files are not changed.</p> <p>Here is a guide to installing and using xtopdf:</p> <p><a href="http://jugad2.blogspot.in/2012/07/guide-to-installing-and-using-xtopdf.html" rel="nofollow">http://jugad2.blogspot.in/2012/07/guide-to-installing-and-using-xtopdf.html</a></p> <p>More details on running the program, and sample output, are available here:</p> <p><a href="http://jugad2.blogspot.in/2016/12/xtopdf-wildcard-text-files-to-pdf-with.html" rel="nofollow">http://jugad2.blogspot.in/2016/12/xtopdf-wildcard-text-files-to-pdf-with.html</a></p>

NOTE: does not work with plain old non-instance-method functions. The cache is stored on the instance to prevent memory leaks caused by long-term caching beyond the life of the instance (almost all other recipes I found suffer from this problem when used with instance methods).</p>

Revision 2. </p> <p>In some applications, it's advantageous to be able to define a fixed length list.</p> <p>The class provides all features as python internal type: list</p> <p>The main focus of <strong>fixed length</strong> list is only keep certain number of items. "overflow" items will be discarded.</p>

Revision 2. </p> <p>An easily extensible class, inheriting from Canvas, which can be used to define geometry in a more mathematical way. So rather than specify a circle from 2 points you give a radius and a centre. These could have colour as a keyword argument but personally I always want to specify the colour.</p>

Revision 5. </p> <p>A class decorator that ensures that only one instance of the class exists for each distinct set of constructor arguments.</p> <p>Note that if a decorated class is subclassed, each subclass is cached separately. (This is because each cached subclass is a different <code>cls</code> argument to the <code>__new__</code> method.)</p>

Revision 2. </p> <p>A tiny script to display the entire contents of a medium sized git repository. It will display tags, branches and commits with different shapes and colours and the commits messages in a dimmed colour. </p> <p>It relies on graphviz to do the plotting. Use it like so </p> <pre class="prettyprint"><code> ruby plotrepo.rb /path/to/repository | dot -Tpng | display -antialias </code></pre>

<p style="color: grey"> Python recipe 577496 by <a href="/recipes/users/2035254/">Nick Coghlan</a> (<a href="/recipes/tags/logging/">logging</a>). </p> <p>Creation of log message handler for the logging module is often a multi-step process, involving creation of the handler object, configuration of the message levels and formats, installation of any filters and then actual connection of the handler to the relevant logger object.</p> <p>This helper function allows all of these things to be specified up front in a single function call, which then takes care of configuring the handler object appropriately.</p>

Unfortunately I found that it was easy to get Komodo to crash on shutdown. Meanwhile I wanted to build a framework to make it easier to build these.</p> <p>This recipe accomplishes both. It looks like putting a listener on a view object can trigger this crash, but so can storing a method on a view object, even with a unique name. So while I wanted to use the "view.view_closing" event, I can't, and I notice no other core Komodo code is. The template instead uses a global hash, ko.extensions.togglers, to store the code objects. And now I'm not getting a crash.</p>
