<p>The <a class="reference internal" href="#cmd.Cmd" title="cmd.Cmd"><code class="xref py py-class docutils literal"><span class="pre">Cmd</span></code></a> class provides a simple framework for writing line-oriented
82
command interpreters. These are often useful for test harnesses, administrative
83
tools, and prototypes that will later be wrapped in a more sophisticated

<dd><p>A <a class="reference internal" href="#cmd.Cmd" title="cmd.Cmd"><code class="xref py py-class docutils literal"><span class="pre">Cmd</span></code></a> instance or subclass instance is a line-oriented interpreter
89
framework. There is no good reason to instantiate <a class="reference internal" href="#cmd.Cmd" title="cmd.Cmd"><code class="xref py py-class docutils literal"><span class="pre">Cmd</span></code></a> itself; rather,
90
it’s useful as a superclass of an interpreter class you define yourself in order
91
to inherit <a class="reference internal" href="#cmd.Cmd" title="cmd.Cmd"><code class="xref py py-class docutils literal"><span class="pre">Cmd</span></code></a>‘s methods and encapsulate action methods.</p>
92
<p>The optional argument <em>completekey</em> is the <a class="reference internal" href="readline.html#module-readline" title="readline: GNU readline support for Python. (Unix)"><code class="xref py py-mod docutils literal"><span class="pre">readline</span></code></a> name of a completion
93
key; it defaults to <code class="kbd docutils literal"><span class="pre">Tab</span></code>. If <em>completekey</em> is not <a class="reference internal" href="constants.html#None" title="None"><code class="xref py py-const docutils literal"><span class="pre">None</span></code></a> and
94
<a class="reference internal" href="readline.html#module-readline" title="readline: GNU readline support for Python. (Unix)"><code class="xref py py-mod docutils literal"><span class="pre">readline</span></code></a> is available, command completion is done automatically.</p>
95
<p>The optional arguments <em>stdin</em> and <em>stdout</em> specify the input and output file
96
objects that the Cmd instance or subclass instance will use for input and
97
output. If not specified, they will default to <a class="reference internal" href="sys.html#sys.stdin" title="sys.stdin"><code class="xref py py-data docutils literal"><span class="pre">sys.stdin</span></code></a> and
98
<a class="reference internal" href="sys.html#sys.stdout" title="sys.stdout"><code class="xref py py-data docutils literal"><span class="pre">sys.stdout</span></code></a>.</p>
99
<p>If you want a given <em>stdin</em> to be used, make sure to set the instance’s

<p>A <a class="reference internal" href="#cmd.Cmd" title="cmd.Cmd"><code class="xref py py-class docutils literal"><span class="pre">Cmd</span></code></a> instance has the following methods:</p>

113
<dd><p>Repeatedly issue a prompt, accept input, parse an initial prefix off the
114
received input, and dispatch to action methods, passing them the remainder of
115
the line as argument.</p>
116
<p>The optional argument is a banner or intro string to be issued before the first
117
prompt (this overrides the <a class="reference internal" href="#cmd.Cmd.intro" title="cmd.Cmd.intro"><code class="xref py py-attr docutils literal"><span class="pre">intro</span></code></a> class attribute).</p>
118
<p>If the <a class="reference internal" href="readline.html#module-readline" title="readline: GNU readline support for Python. (Unix)"><code class="xref py py-mod docutils literal"><span class="pre">readline</span></code></a> module is loaded, input will automatically inherit
119
<strong class="program">bash</strong>-like history-list editing (e.g. <code class="kbd docutils literal"><span class="pre">Control-P</span></code> scrolls back
120
to the last command, <code class="kbd docutils literal"><span class="pre">Control-N</span></code> forward to the next one, <code class="kbd docutils literal"><span class="pre">Control-F</span></code>
121
moves the cursor to the right non-destructively, <code class="kbd docutils literal"><span class="pre">Control-B</span></code> moves the
122
cursor to the left non-destructively, etc.).</p>
123
<p>An end-of-file on input is passed back as the string <code class="docutils literal"><span class="pre">'EOF'</span></code>.</p>
124
<p>An interpreter instance will recognize a command name <code class="docutils literal"><span class="pre">foo</span></code> if and only if it
125
has a method <code class="xref py py-meth docutils literal"><span class="pre">do_foo()</span></code>. As a special case, a line beginning with the
126
character <code class="docutils literal"><span class="pre">'?'</span></code> is dispatched to the method <code class="xref py py-meth docutils literal"><span class="pre">do_help()</span></code>. As another
127
special case, a line beginning with the character <code class="docutils literal"><span class="pre">'!'</span></code> is dispatched to the
128
method <code class="xref py py-meth docutils literal"><span class="pre">do_shell()</span></code> (if such a method is defined).</p>
129
<p>This method will return when the <a class="reference internal" href="#cmd.Cmd.postcmd" title="cmd.Cmd.postcmd"><code class="xref py py-meth docutils literal"><span class="pre">postcmd()</span></code></a> method returns a true value.
130
The <em>stop</em> argument to <a class="reference internal" href="#cmd.Cmd.postcmd" title="cmd.Cmd.postcmd"><code class="xref py py-meth docutils literal"><span class="pre">postcmd()</span></code></a> is the return value from the command’s
131
corresponding <code class="xref py py-meth docutils literal"><span class="pre">do_*()</span></code> method.</p>
132
<p>If completion is enabled, completing commands will be done automatically, and
133
completing of commands args is done by calling <code class="xref py py-meth docutils literal"><span class="pre">complete_foo()</span></code> with
134
arguments <em>text</em>, <em>line</em>, <em>begidx</em>, and <em>endidx</em>. <em>text</em> is the string prefix
135
we are attempting to match: all returned matches must begin with it. <em>line</em> is
136
the current input line with leading whitespace removed, <em>begidx</em> and <em>endidx</em>
137
are the beginning and ending indexes of the prefix text, which could be used to
138
provide different completion depending upon which position the argument is in.</p>
139
<p>All subclasses of <a class="reference internal" href="#cmd.Cmd" title="cmd.Cmd"><code class="xref py py-class docutils literal"><span class="pre">Cmd</span></code></a> inherit a predefined <code class="xref py py-meth docutils literal"><span class="pre">do_help()</span></code>. This
140
method, called with an argument <code class="docutils literal"><span class="pre">'bar'</span></code>, invokes the corresponding method
141
<code class="xref py py-meth docutils literal"><span class="pre">help_bar()</span></code>, and if that is not present, prints the docstring of
142
<code class="xref py py-meth docutils literal"><span class="pre">do_bar()</span></code>, if available. With no argument, <code class="xref py py-meth docutils literal"><span class="pre">do_help()</span></code> lists all
143
available help topics (that is, all commands with corresponding
144
<code class="xref py py-meth docutils literal"><span class="pre">help_*()</span></code> methods or commands that have docstrings), and also lists any
145
undocumented commands.</p>
