Revision 3. </p> <p>This hack runs a command sequentially on a list of files using two simultaneous threads. If one of the commands takes more than a set time, it's killed and the program goes for the next file. EDITED to add some exception handling.</p>

<p style="color: grey"> Python recipe 577711 by <a href="/recipes/users/4177816/">Eric Snow</a> (<a href="/recipes/tags/abc/">abc</a>, <a href="/recipes/tags/validation/">validation</a>). Revision 4. </p> <p>Abstract Bases Classes in Python provide great features for describing interfaces programmatically. By default a subclass is validated against all its ABC parents at instantiation time (in object.__new__). This recipe aims to provide for validation against an ABC of:</p> <ul> <li>any class at definition time (including subclasses and registered classes),</li> <li>any object at any time.</li> </ul> <p>I have included an example of the reason I did all this. It allows you to implement an ABC in the instance rather than the class.</p> <p>If the classes argument to validate is None then it tries to build the list of classes from the object's MRO. If the ABCMeta.register method facilitated an __implements__ list on classes, we could also use that to validate against the registered "base" classes.</p> <p>The code I have provided is for Python 3, but it should work in 2.7 with a little modification.</p> <p>This code borrows from Lib/abc.py and objects/typeobject.c</p>

Revision 3. </p> <p>Save this to "nicerest", <code>chmod +x</code>-it, and pipe your REST API <code>curl</code> calls through this for nicer output. It will notice HTTP headers (curl's <code>-i</code> option) and skips those before attempting to pretty-print the following JSON.</p> <p>Note: This is currently using node 0.2. I should update for 0.3 changes (I think <code>process.openStdin</code> changed).</p>
