Some helpers for python's argparse.
Currently, this package provides 3 HelpFormatter classes that you can extend and / or use with
python's argparse
module:
Contents
WideHelpFormatter
HelpFormatter which tries to use a given amount of the terminal width.
The maximum line length is determines by the class attribute percentage_of_line_length
.
This defaults to the full width (1.0). Override this class and set your own percentage.
This uses shutil.get_terminal_size()
to determine the line length.
ThreeQuarterWidthHelpFormatter
A WideHelpFormatter
subclass with its percentage_of_line_length
set to three quarters of the terminal line length.
ThreeQuarterWidthDefaultsHelpFormatter
A ThreeQuarterWidthHelpFormatter
subclass which also derives from argparse.ArgumentDefaultsHelpFormatter
. This means that in addition to using 3/4 of the terminal line length, it also prints the argument defaults in the help text.
Usage
Use these classes in the same way as any other argparse.HelpFormatter
subclass while creating your argument parser:
parser = argparse.ArgumentParser(formatter_class=<HelpFormatter>)
parser.add_argument(...)
