Example using all available arguments

import cpick

# keyword argument dictionary
kwargs = {
	# list to feed into the picker
	'items': ['a', 'list', 'of', 'items'],
	# only allow five items to be picked, defaults to sys.maxsize
	'limit': 5,
	# turn line numbering on
	'numbers': True,
	# defaults to 'PICK ITEMS FROM THIS LIST'
	'header': 'My Awesome Custom Header',
	# defaults to 'Press [?] to view keybindings'
	'footer': 'My Awesome Custom Footer',
}

# splat args using ** to unpack kwargs dictionary
picked = cpick.pick(**kwargs)

# print picked list
print(*picked, sep=", ")
# output if all items picked: a, list, of, items

Example using only a list

# pass in only mandatory arg - a list.
picked = cpick.pick(items=['just', 'a', 'list'])
print(*picked, sep=", ")
# output if all items picked: just, a, list

KEYBINDINGS

NOTES

Picking[;], toggling [:], and searching[/] is supported via the following methods:

• Unix Style Wildcards.

• Regular Expressions.

• Matching a complete string (ie. not substrings - use wildcards for this.)

• Specifying the line number of an item.

• Specifying a range of line numbers in the following forms:

  PROMPT	ACTION
  x..y	Match line numbers between x and y
  x-y	Match line numbers between x and y
  x..	Match line numbers from x until the end of the list
  ..y	Match line numbers from beginning of list until y
  x-	Match line numbers from x until the end of the list
  -y	Match line numbers from beginning of list until y

These can also be combined. You can enter multiple patterns, ranges and strings at one Pick:, Toggle: or Find: prompt.

However, be aware, that when toggling - if patterns, ranges or strings are entered that match the same items, they will cancel each other out.

For example, if you entered 1..10 ^[A-Z][a-z]+$ on a list where the first 10 items were capitalised words, nothing would be picked.

The 1..10 would pick the first ten items, and then the ^[A-Z][a-z]+$ would unpick them, since they call the toggle method consecutively.

If you do not want this (you probably don't..) - use the Pick: prompt instead.

EXAMPLES

Pick a number from 1 to 100, using custom header/footer and limiting picks to 5.

cpick --header "My header" --footer "My footer" --limit 5 {1..100}

Pick 5 random words from the dictionary, using the default header/footer.

cpick --limit 5 $(shuf -n 100 /usr/share/dict/words)

Pick an unlimited number of paths from the current directory.

cpick $(ls)
