CLIArgs: Absolutely Trivial Command-line Arguments ================================================== Doesn't parsing command line arguments suck? At best, you use ``optparse``, and then if that doesn't work you hand-code it. Or, you use ``getargs``, which requires writing your own loops. Don't you wish for something a little bit... smarter? CLIArgs makes argument parsing a piece of cake. Basics ------ Define a few functions, change your ``if __name__ == "__main__"`` block, and CLIArgs does the rest:: import cliargs __help__ = "clone source [destinations] [-v]" __version__ = "1.0" def __main__(source, *dest, verbose=False): ... if __name__ == "__main__": cliargs.main() If you run this file (``clone``), the following command lines will all do the obvious:: clone a b c d e clone --source=a b c d e clone a b -v clone --help clone -? clone --version In general, all arguments to the function ``__main__`` are examined, based on which the command line will be intelligently parsed. If necessary, the help and version info will be displayed. Finally, most errors in parsing command-lines are caught and a summary prepared for the user. Argument types -------------- The basic algorithm will examine the arguments of the function (that is, of ``__main__``) and assign, for each arguments, a short and long argument, and a type. The long argument is always the name of argument; the short argument is, in order, the short name is the first letter of this short argument, or (if that is unavailable) the swapcase'd version of that letter, or one of a built-in list of exceptions. These are assigned left-to-right. The type of any argument is by default assumed to be a string. However, if the argument is given a default value (as is ``verbose`` in the example above), the type of the default argument is used. If the type is a string, the command-line argument is simply passed to the function. However, integers and floats are converted into true integers and floats, booleans make their corresponding arguments into flags (such as ``verbose`` above), lists are created by splitting a single comma-delimited argument (that means that there cannot be spaces between the arguments; use ``--list=1,2,3,4`` or similar constructions) and dictionaries by splitting by commas, then equal signs (e.g. ``--dict=a=1,b=2,c=3``). Of course, list and dictionary arguments are usually better handled by the ``*args`` and ``**kwargs`` parameters. Help & Version -------------- The help information is taken from a function called ``__help__``, a string named ``__help__``, or the module documentation. If ``__help`` is a function, it is called, with all of the arguments after the first ``-?`` (or ``-h`` or `--help``) passed as arguments; thus, it it best that ``__help__`` take a variable number of arguments. Otherwise, ``__help__`` is assumed to be a string and is printed. ``__version__`` can likewise be either a string or a function; as a function, it is called without arguments. Use Beyond Argument Parsing --------------------------- Sometimes, we want to parse arguments other than those in ``sys.argv``, such as for a built-in shell. One can use CLIArgs to provide a similarly-shiny tool for this purpose as well. Simply use the function ``cliargs.run(function, arguments, help=None, version=None)``.
