==============================================================================

**Y**\ et **A**\ nother Terminal **Spin**\ ner for Python.

**Yaspin** provides a full-featured terminal spinner to show the progress during long-hanging operations.

.. image:: https://raw.githubusercontent.com/pavdmyt/yaspin/master/gifs/demo.gif

It is easy to integrate into existing codebase by using it as a `context manager`_
or as a function `decorator`_:

.. code:: python

    import time
    from yaspin import yaspin

    # Context manager:
    with yaspin():
        time.sleep(3)  # time consuming code

    # Function decorator:
    @yaspin(text="Loading...")
    def some_operations():
        time.sleep(3)  # time consuming code

    some_operations()


Features
--------

- No external dependencies
- Runs at all major **CPython** versions (*2.6*, *2.7*, *3.3*, *3.4*, *3.5*, *3.6*), **PyPy** and **PyPy3**
- Supports all (60+) spinners from `cli-spinners`_
- Supports all *colors*, *highlights*, *attributes* and their mixes from `termcolor`_ library
- Flexible API, easy to integrate with existing code
- Safe **pipes** and **redirects**:

.. code-block:: bash

    $ python script_that_uses_yaspin.py > script.log
    $ python script_that_uses_yaspin.py | grep ERROR


Installation
------------

From `PyPI`_ using ``pip`` package manager:

.. code-block:: bash

    pip install --upgrade yaspin


Or install the latest sources from GitHub:

.. code-block:: bash

    pip install https://github.com/pavdmyt/yaspin/archive/master.zip


Usage
-----

Basic Example
/////////////

.. image:: https://raw.githubusercontent.com/pavdmyt/yaspin/master/gifs/basic_example.gif

.. code:: python

    # -*- coding: utf-8 -*-
    import time
    from random import randint
    from yaspin import yaspin

    with yaspin(text="Loading", color="yellow") as spinner:
        time.sleep(2)  # time consuming code

        success = randint(0, 1)
        if success:
            spinner.ok("✅ ")
        else:
            spinner.fail("💥 ")


It is also possible to control spinner manually:

.. code:: python

    # -*- coding: utf-8 -*-
    import time
    from yaspin import yaspin

    spinner = yaspin()
    spinner.start()

    time.sleep(3)  # time consuming tasks

    spinner.stop()


Run any spinner from `cli-spinners`_
////////////////////////////////////

.. image:: https://raw.githubusercontent.com/pavdmyt/yaspin/master/gifs/cli_spinners.gif

.. code:: python

    # -*- coding: utf-8 -*-
    import time
    from yaspin import yaspin
    from yaspin.spinners import Spinners

    with yaspin(Spinners.earth, text="Earth") as sp:
        time.sleep(2)                # time consuming code

        # change spinner
        sp.spinner = Spinners.moon
        sp.text = "Moon"

        time.sleep(2)                # time consuming code


Any Colour You Like `🌈`_
/////////////////////////

.. image:: https://raw.githubusercontent.com/pavdmyt/yaspin/master/gifs/basic_colors.gif

.. code:: python

    # -*- coding: utf-8 -*-
    import time
    from yaspin import yaspin

    with yaspin(text="Colors!") as sp:
        # Support all basic termcolor text colors
        colors = ("red", "green", "yellow", "blue", "magenta", "cyan", "white")

        for color in colors:
            sp.color, sp.text = color, color
            time.sleep(1)


Advanced colors usage
/////////////////////

.. image:: https://raw.githubusercontent.com/pavdmyt/yaspin/master/gifs/advanced_colors.gif

.. code:: python

    # -*- coding: utf-8 -*-
    import time
    from yaspin import yaspin
    from yaspin.spinners import Spinners
    from yaspin.termcolor import colored

    text = "Bold blink magenta spinner on cyan color"
    # Support all termcolor features via simple closure
    color_fn = lambda frame: colored(frame, "magenta", "on_cyan", attrs=["bold", "blink"])

    with yaspin(Spinners.bouncingBall, text=text, color=color_fn):
        time.sleep(3)


Run any spinner you want
////////////////////////

.. image:: https://raw.githubusercontent.com/pavdmyt/yaspin/master/gifs/custom_spinners.gif

.. code:: python

    # -*- coding: utf-8 -*-
    import time
    from yaspin import yaspin, Spinner

    # Compose new spinners with custom frame sequence and interval value
    sp = Spinner(["😸", "😹", "😺", "😻", "😼", "😽", "😾", "😿", "🙀"], 200)

    with yaspin(sp, text="Cat!"):
        time.sleep(3)  # cat consuming code :)


Change spinner properties on the fly
////////////////////////////////////

.. image:: https://raw.githubusercontent.com/pavdmyt/yaspin/master/gifs/sp_properties.gif

.. code:: python

    # -*- coding: utf-8 -*-
    import time
    from yaspin import yaspin
    from yaspin.spinners import Spinners

    with yaspin(Spinners.noise, text="Noise spinner") as sp:
        time.sleep(2)

        sp.spinner = Spinners.arc  # spinner type
        sp.text = "Arc spinner"    # text along with spinner
        sp.color = "green"         # spinner color
        sp.right = True            # put spinner to the right
        sp.reverse = True          # reverse spin direction

        time.sleep(2)


Writing messages
////////////////

.. image:: https://raw.githubusercontent.com/pavdmyt/yaspin/master/gifs/write_text.gif

You should not write any message in the terminal using ``print`` while spinner is open.
To write messages in the terminal without any collision with ``yaspin`` spinner, a ``.write()`` method is provided:

.. code:: python

    # -*- coding: utf-8 -*-
    import time
    from yaspin import yaspin

    with yaspin(text="Downloading images", color="cyan") as sp:
        # task 1
        time.sleep(1)
        sp.write("> image 1 download complete")

        # task 2
        time.sleep(2)
        sp.write("> image 2 download complete")

        # finalize
        sp.ok("✔")
