47<h1>Python XPCOM Package</h1>
48
49<p>Mozilla CVS Version - Last updated May 2002</p>
50<p>This is the readme for the Python interface to <b>XPCOM</b>.</p>
51<p><b>XPCOM </b>is an acronym for &quot;Cross Platform COM&quot;.&nbsp; It has
52come out of the <a href="http://www.mozilla.org">Mozilla</a> project, which
53maintains the <a href="http://www.mozilla.org/projects/xpcom/">main XPCOM
54project pages.</a>&nbsp; The Python XPCOM package is a set of Python bindings to
55XPCOM, allowing a Python programmer to both use and implement XPCOM
56interfaces.&nbsp; If you don't know what <a href="http://www.python.org">Python</a>
57is, then none of this probably interests you at all!</p>
58<p>This readme has links to the following information:</p>
59<ul>
60 <li><a href="doc/configure.html">Building, Configuring and
61 Testing the Python
62 XPCOM Package</a></li>
63 <li><a href="doc/tutorial.html">A tutorial for the Python XPCOM package</a></li>
64 <li>Some <a href="doc/advanced.html">advanced
65 topics and other miscellaneous information</a></li>
66 <li><a href="doc/architecture.html">Information on the architecture</a></li>
67 <li>A list of the <a href="#KnownBugs">known issues and bugs</a>, the <a href="#ReleaseHistory">release
68 history</a> and the <a href="doc/credits.html">PyXPCOM acknowledgements</a></li>
69</ul>
70<p>Note: <b>This package requires Python 1.6 or later</b>; we recommend using
71the latest
72official Python version.&nbsp; This package works
73very well with the latest <a href="http://www.ActiveState.com/Products/ActivePython">ActivePython</a>,
74and does not require any external modules or packages beyond what is provided in
75the core Python release for each platform.</p>
76<h2>About the Python XPCOM Package</h2>
77<p>The Python XPCOM Package was developed by <a href="http://www.ActiveState.com">ActiveState
78Tool Corporation</a>, and came out of their <a href="http://www.ActiveState.com/Products/Komodo">Komodo
79project</a>.&nbsp; The Python XPCOM package is released under the <a href="http://www.mozilla.org/MPL/">Mozilla
80Public License (MPL)</a></p>
81<p>Please see the <a href="doc/credits.html">credits file</a> for a list of
82contributors. </p>
83<h2><a name="KnownBugs">Known Bugs</a>/Issues</h2>
84<ul>
85 <li>No attempt is made to recurse sub-directories of the main
86&quot;components&quot; directory.&nbsp; This is because we may decide on some
87smart scheme for recursion (similar to Python packages), and don't want people
88to rely on simple recursive searches.</li>
89 <li>No unregistration support at all.&nbsp;The main Python Component Loader supports
90 unregistration, but the actual Python objects themselves do not support unregistration.&nbsp;It is unclear if the Component Loader
91 unregistration process needs to manually remove each component it is responsible
92for.</li>
93 <li>All Python-implemented components unconditionally support
94weak-references.&nbsp; There is no way to disable this feature for any or all
95components.&nbsp; It is unclear if there is a need to prevent this, but it is
96documented here just in case!</li>
97</ul>
98<h2><a name="ReleaseHistory">Release History</a></h2>

107</ul>
108
109<h3>Version 0.92 - May 2001</h3>
110<p>Implement interface flattening.&nbsp; You should (almost) never need to use <i>QueryInterface()</i>!&nbsp;
111We are still 100% backwards compatible, so usage of QI still works - just is
112generally not necessary.</p>
113
114<h3>Version 0.93 - May 2002</h3>
115
116<p>Implement <i>nsIVariant</i> and all new string types.&nbsp; Complete move to
