<span class="sd">"""Command-line parsing library</span>
|
||
|
|
|
||
|
|
<span class="sd">This module is an optparse-inspired command-line parsing library that:</span>
|
||
|
|
|
||
|
|
<span class="sd"> - handles both optional and positional arguments</span>
|
||
|
|
<span class="sd"> - produces highly informative usage messages</span>
|
||
|
|
<span class="sd"> - supports parsers that dispatch to sub-parsers</span>
|
||
|
|
|
||
|
|
<span class="sd">The following is a simple usage example that sums integers from the</span>
|
||
|
|
<span class="sd">command-line and writes the result to a file::</span>
|
||
|
|
|
||
|
|
<span class="sd"> parser = argparse.ArgumentParser(</span>
|
||
|
|
<span class="sd"> description='sum the integers at the command line')</span>
|
||
|
|
<span class="sd"> parser.add_argument(</span>
|
||
|
|
<span class="sd"> 'integers', metavar='int', nargs='+', type=int,</span>
|
||
|
|
<span class="sd"> help='an integer to be summed')</span>
|
||
|
|
<span class="sd"> parser.add_argument(</span>
|
||
|
|
<span class="sd"> '--log', default=sys.stdout, type=argparse.FileType('w'),</span>
|
||
|
|
<span class="sd"> help='the file where the sum should be written')</span>
|
||
|
|
<span class="sd"> args = parser.parse_args()</span>
|
||
|
|
<span class="sd"> args.log.write('%s' % sum(args.integers))</span>
|
||
|
|
<span class="sd"> args.log.close()</span>
|
||
|
|
|
||
|
|
<span class="sd">The module contains the following public classes:</span>
|
||
|
|
|
||
|
|
<span class="sd"> - ArgumentParser -- The main entry point for command-line parsing. As the</span>
|
||
|
|
<span class="sd"> example above shows, the add_argument() method is used to populate</span>
|
||
|
|
<span class="sd"> the parser with actions for optional and positional arguments. Then</span>
|
||
|
|
<span class="sd"> the parse_args() method is invoked to convert the args at the</span>
|
||
|
|
<span class="sd"> command-line into an object with attributes.</span>
|
||
|
|
|
||
|
|
<span class="sd"> - ArgumentError -- The exception raised by ArgumentParser objects when</span>
|
||
|
|
<span class="sd"> there are errors with the parser's actions. Errors raised while</span>
|
||
|
|
<span class="sd"> parsing the command-line are caught by ArgumentParser and emitted</span>
|
||
|
|
<span class="sd"> as command-line messages.</span>
|
||
|
|
|
||
|
|
<span class="sd"> - FileType -- A factory for defining types of files to be created. As the</span>
|
||
|
|
<span class="sd"> example above shows, instances of FileType are typically passed as</span>
|
||
|
|
<span class="sd"> the type= argument of add_argument() calls.</span>
|
||
|
|
|
||
|
|
<span class="sd"> - Action -- The base class for parser actions. Typically actions are</span>
|
||
|
|
<span class="sd"> selected by passing strings like 'store_true' or 'append_const' to</span>
|
||
|
|
<span class="sd"> the action= argument of add_argument(). However, for greater</span>
|
||
|
|
<span class="sd"> customization of ArgumentParser actions, subclasses of Action may</span>
|
||
|
|
<span class="sd"> be defined and passed as the action= argument.</span>
|
||
|
|
|
||
|
|
<span class="sd"> - HelpFormatter, RawDescriptionHelpFormatter, RawTextHelpFormatter,</span>
|
||
|
|
<span class="sd"> ArgumentDefaultsHelpFormatter -- Formatter classes which</span>
|
||
|
|
<span class="sd"> may be passed as the formatter_class= argument to the</span>
|
||
|
|
<span class="sd"> ArgumentParser constructor. HelpFormatter is the default,</span>
|
||
|
|
<span class="sd"> RawDescriptionHelpFormatter and RawTextHelpFormatter tell the parser</span>
|
||
|
|
<span class="sd"> not to change the formatting for help text, and</span>
|
||
|
|
<span class="sd"> ArgumentDefaultsHelpFormatter adds information about argument defaults</span>
|
||
|
|
<span class="sd"> to the help.</span>
|
||
|
|
|
||
|
|
<span class="sd">All other classes in this module are considered implementation details.</span>
|
||
|
|
<span class="sd">(Also note that HelpFormatter and RawDescriptionHelpFormatter are only</span>
|
||
|
|
<span class="sd">considered public as object names -- the API of the formatter objects is</span>
|
||
|
|
<span class="sd">still considered an implementation detail.)</span>
