<h1 class="title">Developing twill</h1>
<p>twill is entirely written in Python.  You will need Python 2.3 or later
to develop it.</p>
<div class="section">
<h1><a id="package-tests" name="package-tests">Package tests</a></h1>
<p>twill comes with several unit tests.  They depend on <a class="reference" href="http://somethingaboutorange.com/mrl/projects/nose/">nose</a> and
<a class="reference" href="http://www.mems-exchange.org/software/quixote/">Quixote 2.3</a>.  To run them, type 'python setup.py test'
in the top package directory.</p>
</div>
<div class="section">

<div class="section">
<h1><a id="developer-releases" name="developer-releases">Developer releases</a></h1>
<p>&quot;Developer releases&quot; incorporating all recent significant changes are
made available at <a class="reference" href="http://darcs.idyll.org/~t/projects/twill-latest.tar.gz">http://darcs.idyll.org/~t/projects/twill-latest.tar.gz</a></p>
<p>You can install them with easy_install by typing</p>

<p><a class="reference" href="http://abridgegame.org/darcs/">darcs</a> is a distributed version control system that allows users to
maintain their own versions of various programs.  It's a convenient
way for me to make the latest source code available quickly, and
it also is a dandy way to submit patches.</p>
<p>To obtain twill using darcs, install darcs and then type</p>
<pre class="literal-block">
darcs get http://darcs.idyll.org/~t/projects/twill/
</pre>
<p>To propose a change to the lead developer, make the changes and
then do a 'send':</p>
<pre class="literal-block">
darcs record -am &quot;explanation of change&quot;
darcs send -a
</pre>
<p>To pull in changes made by the lead developer some time later:</p>
<pre class="literal-block">
darcs pull
</pre>
</div>
<div class="section">
<h1><a id="advanced-documentation" name="advanced-documentation">Advanced documentation</a></h1>
<p>twill uses a melange of different packages.  Here are some potentially
useful links:</p>
<blockquote>
<ul class="simple">
<li><a class="reference" href="http://www.voidspace.org.uk/python/articles/urllib2.shtml">urllib2.py: the missing manual</a> -- a detailed discussion of urllib2
functionality that can be directly applied to twill.</li>
</ul>
</blockquote>
<div class="section">
<h2><a id="future-plans" name="future-plans">Future Plans</a></h2>
<p>TODO:</p>
<p>for 9.0 (beta).</p>
<blockquote>
<ol class="arabic simple">
<li>RECORDING.</li>
<li>execute directories/directory trees.</li>
<li>expose 'browser' &amp; document re Grig; regexp esp.; make source docs.</li>
<li>twill-fork: make file writing stuff optional; test massive fork fn.</li>
<li>add config directives for socket timeout.</li>
<li>directory stuff: import from specific place, access script location.</li>
</ol>
</blockquote>
<p>Misc fixes &amp; cleanups:</p>
<blockquote>
<ol class="arabic simple">
<li>Paul McGuire's pyparsing suggestions.</li>
<li>cookie &quot;1&quot; vs 1, in cookielib.</li>
<li>extend_with etc. -- module namespaces, e.g. extmodule.fn?</li>
<li>implement more complex proxy support.  proxies proxies proxies.</li>
<li>'history' to show command history...</li>
<li>record commands to script</li>
<li>command line option for stdout -&gt; file</li>
</ol>
</blockquote>
<p>Random ideas:</p>
<blockquote>
<ol class="arabic">
<li><p class="first">Build twill interfaces for zope.testbrowser and mechanoid and pycurl.</p>
<p>(This shouldn't be too difficult, since both are based on mechanize...)</p>
</li>
<li><p class="first">Develop twill-like languages for <a class="reference" href="http://pamie.sourceforge.net/">PAMIE</a> and <a class="reference" href="http://kb.mozillazine.org/PyXPCOM">PyXPCOM</a>.  Note that the
hard work, at least for PAMIE, is already done; check out the
<a class="reference" href="tutoriala.html">PAMIE examples page</a>.</p>
