<ol class="arabic simple">
<li>Focus on either the client or server code. This focuses the development process down to the precise pieces of code that matter for the task at hand.<ul>
<li>If you are developing a client driver, then write up a small configuration specification that includes the needed characteristics.</li>
<li>If you are working on the server, run <tt class="docutils literal"><span class="pre">bcfg2-info</span></tt> and use to assess the code.</li>
</ul>
</li>
<li>Use the python interpreter. One of python’s most appealing features is interactive use of the interpreter.<ul>
<li>If you are developing for the client-side, run <tt class="docutils literal"><span class="pre">python</span> <span class="pre">-i</span> <span class="pre">/usr/sbin/bcfg2</span></tt> with the appropriate bcfg2 options. This will cause the python interpreter to continue running, leaving all variables intact. This can be used to examine data state in a convenient fashion.</li>
<li>If you are developing for the server side, use <tt class="docutils literal"><span class="pre">bcfg2-info</span></tt> and the “debug” option. This will leave you at a python interpreter prompt, with the server core loaded in the variable “bcore”.</li>
</ul>
</li>
<li>Use <tt class="docutils literal"><span class="pre">pylint</span></tt> obsessively. It raises a lot of style-related warnings which can be ignored, but most all of the errors are legitimate.</li>
<li>If you are doing anything with Regular Expressions, <a class="reference external" href="http://kodos.sourceforge.net">Kodos</a> and <a class="reference external" href="http://re-try.appspot.com">re-try</a> are your friends.</li>
