args

Argument Parsing for Humans.

Usage

Here's an example application:

import args

print 'Arguments passed in: ' + str(args.all)
print 'Flags detected: ' + str(args.flags)
print 'Files detected: ' + str(args.files)
print 'NOT files detected: ' + str(args.not_files)
print 'Grouped Arguments: ' + str(args.grouped)
print 'Assignments detected: ' + str(args.assignments)

No arguments:

$ tool
Arguments passed in: []
Flags detected: <args []>
Files detected: []
NOT files detected: <args []>
Grouped Arguments: OrderedDict([('_', <args []>)])
Assignments detected: OrderedDict()

A few arguments:

$ tool -s yes no --number=one --letter a b c --number=two
Arguments passed in: ['-s', 'yes', 'no', '--number=one', '--letter', 'a', 'b', 'c', '--number=two']
Flags detected: <args ['-s', '--number=one', '--letter', '--number=two']>
Files detected: []
NOT files detected: <args ['-s', 'yes', 'no', '--number=one', '--letter', 'a', 'b', 'c', '--number=two']>
Grouped Arguments: OrderedDict([('_', <args []>), ('-s', <args ['yes', 'no']>), ('--number=one', <args []>), ('--letter', <args ['a', 'b', 'c']>), ('--number=two', <args []>)])
Assignments detected: OrderedDict([('--number', <args ['one', 'two']>)])

A few expanded file arguments:

$ tool *.py
Arguments passed in: ['args.py', 'setup.py', 'tests.py']
Flags detected: <args []>
Files detected: ['args.py', 'setup.py', 'tests.py']
NOT files detected: <args []>
Grouped Arguments: OrderedDict([('_', <args ['args.py', 'setup.py', 'tests.py']>)])
Assignments detected: OrderedDict()

A few non-expanded file arguments:

$ tool '*.py'
Arguments passed in: ['*.py']
Flags detected: <args []>
Files detected: ['args.py', 'setup.py', 'tests.py']
NOT files detected: <args []>
Grouped Arguments: OrderedDict([('_', <args ['*.py']>)])
Assignments detected: OrderedDict()

A few mixed files/flags/arguments:

Arguments passed in: ['*.py', '--letter', 'a', 'b', 'c', '-s', '/home/example/.example', '--number=one', '--number=two']
Flags detected: <args ['--letter', '-s', '--number=one', '--number=two']>
Files detected: ['setup.py', 'args.py', 'tool.py', 'tests.py', '/home/example/.example/two', '/home/example/.example/one']
NOT files detected: <args ['--letter', 'a', 'b', 'c', '-s', '--number=one', '--number=two']>
Grouped Arguments: OrderedDict([('_', <args ['*.py']>), ('--letter', <args ['a', 'b', 'c']>), ('-s', <args ['/home/example/.example']>), ('--number=one', <args []>), ('--number=two', <args []>)])
Assignments detected: OrderedDict([('--number', <args ['one', 'two']>)])

Installation

Installation is simple with pip:

$ pip install args
