**pick** is a small python library to help you create curses based interactive selection
list in the terminal. See it in action:

![Demo](example/basic.gif?raw=true)


### Installation

$ pip install pick

### Usage

**pick** comes with a simple api:

>>> from pick import pick

>>> title = 'Please choose your favorite programming language: '
>>> options = ['Java', 'JavaScript', 'Python', 'PHP', 'C++', 'Erlang', 'Haskell']
>>> option, index = pick(options, title)
>>> print option
>>> print index

**outputs**

>>> C++
>>> 4

**pick** multiselect example:

>>> from pick import pick

>>> title = 'Please choose your favorite programming language (press SPACE to mark, ENTER to continue): '
>>> options = ['Java', 'JavaScript', 'Python', 'PHP', 'C++', 'Erlang', 'Haskell']
>>> selected = pick(options, title, multi_select=True)
>>> print selected

**outputs**

>>> [('Java', 0), ('C++', 4)]


#### Options

* `options`: a list of options to choose from
* `title`: (optional) a title above options list
* `multi_select`: (optional), if set to True its possible to select multiple items by hitting SPACE
* `indicator`: (optional) custom the selection indicator, defaults to *
* `default_index`: (optional) set this if the default selected option is not the first one


#### Register custom handlers

sometimes you may need to register custom handlers to specific keys, you can use the `register_custom_handler` API:

>>> from pick import Picker
>>> title, options = 'Title', ['Option1', 'Option2']
>>> picker = Picker(options, title)
>>> def go_back(picker):
... return None, -1
>>> picker.register_custom_handler(ord('h'), go_back)
>>> option, index = picker.start()

* the custom handler will be called with the `picker` instance as it's parameter.
* the custom handler should either return a two element tuple, or None.
* if None is returned, the picker would continue to run, otherwise the picker will stop and return the tuple.
