<h1 class="title">Regression Testing for epydoc.docparser</h1>
<p>The <cite>epydoc.docparser</cite> module is used to extract API documentation by
parsing the source code of Python files. Its primary interface is
<cite>docparser.parse_docs()</cite>, which takes a module's filename, and returns a
ModuleDoc describing that module and its contents.</p>
<div class="section" id="test-function">
<h1>Test Function</h1>
<p>This test function takes a string containing the contents of a module,
and writes it to a file, uses <cite>docparser.parse_docs()</cite> to parse it, and pretty
prints the resulting ModuleDoc object. The <tt class="docutils literal"><span class="pre">attribs</span></tt> argument
specifies which attributes of the <cite>APIDoc`s should be displayed. The
``show`</cite> argument, if specifies, gives the name of the object in the
module that should be displayed (but the whole module will always be
inspected; this just selects what to display).</p>

<h1>Module Variables from Assignment Statements</h1>
<p>Variables are extracted from any assignment statements in the module,
including statements contained inside of top-level if statements, for
loops, while loops, and try/except/finally blocks. Tuple assignments
are unpacked, when possible.</p>
<p>For simple variable assignments, DocParser creates <cite>VariableDoc</cite> objects
containing the name; a valuedoc with the value (as both an abstract
syntax tree and a string representation); and information about
whether we think the value was imported; is an alias; and is an
instance variable. (For variables generated from module variable
assignments, is_imported and is_instvar will always be False.)</p>

<p>DocParser can also parse 'multi-assignment' statements, containing
more than one assignment. Note that the ValueDoc object is shared;
and all but the rightmost variable are marked as aliases. (As a
result, the value's canonical name will use the name of the rightmost
variable.)</p>
