## Install

```shell
$ pip install halo
```

## Usage

```py
from halo import Halo

spinner = Halo(text='Loading', spinner='dots')
spinner.start()

# Run time consuming work here
# You can also change properties for spinner as and when you want

spinner.stop()
```

Alternatively, you can use halo with Python's `with` statement:

```py
from halo import Halo

with Halo(text='Loading', spinner='dots'):
    # Run time consuming work here
```

Finally, you can use halo as a decorator:

```py
from halo import Halo

@Halo(text='Loading', spinner='dots')
def long_running_function():
    # Run time consuming work here
    pass

long_running_function()
```

## API

#### `Halo([text|text_color|spinner|animation|placement|color|interval|stream|enabled])`

##### `text`
*Type*: `str`

Text shown along with spinner.

##### `text_color`
*Type*: `str`
*Values*: `grey`, `red`, `green`, `yellow`, `blue`, `magenta`, `cyan`, `white`

Color of the spinner text. Defaults to `None`.

##### `spinner`
*Type*: `str|dict`

If string, it should be one of the spinners listed in the given [json](https://github.com/sindresorhus/cli-spinners/blob/dac4fc6571059bb9e9bc204711e9dfe8f72e5c6f/spinners.json) file. If a dict is passed, it should define `interval` and `frames`. Something like:

```py
{
    'interval': 100,
    'frames': ['-', '+', '*', '+', '-']
}
```

Defaults to `dots` spinner. For Windows users, it defaults to `line` spinner.

##### `animation`
*Type*: `str`
*Values*: `bounce`, `marquee`

Animation to apply to the text if it's too large and doesn't fit in the terminal. If no animation is defined, the text will be ellipsed.

##### `placement`
*Type*: `str`
*Values*: `left`, `right`

Which side of the text the spinner should be displayed. Defaults to `left`

##### `color`
*Type*: `str`
*Values*: `grey`, `red`, `green`, `yellow`, `blue`, `magenta`, `cyan`, `white`

Color of the spinner. Defaults to `cyan`.

##### `interval`
*Type*: `float`

Interval between each frame. Defaults to spinner interval (recommended).

##### `stream`
*Type*: `file`

Stream to write the output. Defaults to `sys.stdout`.

##### `enabled`
*Type*: `bool`

Enable or disable the spinner. Defaults to `True`.

### Methods

#### `spinner.stop()`

#### `spinner.clear()`

Clears the spinner. Returns the instance.

#### `spinner.render()`

Manually renders a new frame. Returns the instance.

#### `spinner.frame()`

Returns next frame to be rendered.

#### `spinner.succeed([text])`
