	'items': ['a', 'list', 'of', 'items'],
	# only allow five items to be picked, defaults to sys.maxsize
	'limit': 5,
	# turn line numbering on

## NOTES

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

- [Unix Style Wildcards](https://docs.python.org/3/library/fnmatch.html).
- [Regular Expressions](https://docs.python.org/3/howto/regex.html).
- 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)`
