Colorama makes this work on +Windows, too, by wrapping ``stdout``, stripping ANSI sequences it finds (which +would appear as gobbledygook in the output), and converting them into the +appropriate win32 calls to modify the state of the terminal. On other platforms, +Colorama does nothing. + +This has the upshot of providing a simple cross-platform API for printing +colored terminal text from Python, and has the happy side-effect that existing +applications or libraries which use ANSI sequences to produce colored output on +Linux or Macs can now also work on Windows, simply by calling +``colorama.just_fix_windows_console()`` (since v0.4.6) or ``colorama.init()`` +(all versions, but may have other side-effects – see below). + +An alternative approach is to install ``ansi.sys`` on Windows machines, which +provides the same behaviour for all applications running in terminals. Colorama +is intended for situations where that isn't easy (e.g., maybe your app doesn't +have an installer.) + +Demo scripts in the source code repository print some colored text using +ANSI sequences. Compare their output under Gnome-terminal's built in ANSI +handling, versus on Windows Command-Prompt using Colorama: + +.. image:: https://github.com/tartley/colorama/raw/master/screenshots/ubuntu-demo.png + :width: 661 + :height: 357 + :alt: ANSI sequences on Ubuntu under gnome-terminal. + +.. image:: https://github.com/tartley/colorama/raw/master/screenshots/windows-demo.png + :width: 668 + :height: 325 + :alt: Same ANSI sequences on Windows, using Colorama. + +These screenshots show that, on Windows, Colorama does not support ANSI 'dim +text'; it looks the same as 'normal text'. + +Usage +----- + +Initialisation +.............. + +If the only thing you want from Colorama is to get ANSI escapes to work on +Windows, then run: + +.. code-block:: python + + from colorama import just_fix_windows_console + just_fix_windows_console() + +If you're on a recent version of Windows 10 or better, and your stdout/stderr +are pointing to a Windows console, then this will flip the magic configuration +switch to enable Windows' built-in ANSI support. + +If you're on an older version of Windows, and your stdout/stderr are pointing to +a Windows console, then this will wrap ``sys.stdout`` and/or ``sys.stderr`` in a +magic file object that intercepts ANSI escape sequences and issues the +appropriate Win32 calls to emulate them. + +In all other circumstances, it does nothing whatsoever. Basically the idea is +that this makes Windows act like Unix with respect to ANSI escape handling. + +It's safe to call this function multiple times. It's safe to call this function +on non-Windows platforms, but it won't do anything. It's safe to call this +function when one or both of your stdout/stderr are redirected to a file – it +won't do anything to those streams. + +Alternatively, you can use the older interface with more features (but also more +potential footguns): + +.. code-block:: python + + from colorama import init + init() + +This does the same thing as ``just_fix_windows_console``, except for the +following differences: + +- It's not safe to call ``init`` multiple times; you can end up with multiple + layers of wrapping and broken ANSI support. + +- Colorama will apply a heuristic to guess whether stdout/stderr support ANSI, + and if it thinks they don't, then it will wrap ``sys.stdout`` and + ``sys.stderr`` in a magic file object that strips out ANSI escape sequences + before printing them. This happens on all platforms, and can be convenient if + you want to write your code to emit ANSI escape sequences unconditionally, and + let Colorama decide whether they should actually be output. But note that + Colorama's heuristic is not particularly clever. + +- ``init`` also accepts explicit keyword args to enable/disable various + functionality – see below. + +To stop using Colorama before your program exits, simply call ``deinit()``. +This will restore ``stdout`` and ``stderr`` to their original values, so that +Colorama is disabled. To resume using Colorama again, call ``reinit()``; it is +cheaper than calling ``init()`` again (but does the same thing). + +Most users should depend on ``colorama >= 0.4.6``, and use +``just_fix_windows_console``. The old ``init`` interface will be supported +indefinitely for backwards compatibility, but we don't plan to fix any issues +with it, also for backwards compatibility. + +Colored Output +.............. + +Cross-platform printing of colored text can then be done using Colorama's +constant shorthand for ANSI escape sequences.

The default behaviour is to wrap if ``autoreset`` or + ``strip`` or ``convert`` are True. + + When wrapping is disabled, colored printing on non-Windows platforms will + continue to work as normal.

Zero or +more params are passed to a ````. If no params are passed, it is +generally synonymous with passing a single zero.

It is passed the name of the module or package of the + application. Once it is created it will act as a central registry for + the view functions, the URL rules, template configuration and much more. + + The name of the package is used to resolve resources from inside the + package or the folder the module is contained in depending on if the + package parameter resolves to an actual python package (a folder with + an :file:`__init__.py` file inside) or a standard module (just a ``.py`` file). + + For more information about resource loading, see :func:`open_resource`. + + Usually you create a :class:`Flask` instance in your main module or + in the :file:`__init__.py` file of your package like this:: + + from flask import Flask + app = Flask(__name__) + + .. admonition:: About the First Parameter + + The idea of the first parameter is to give Flask an idea of what + belongs to your application.

The application will work even with `__name__`, thanks + to how resources are looked up. However it will make debugging more + painful. Certain extensions can make assumptions based on the + import name of your application. For example the Flask-SQLAlchemy + extension will look for the code in your application that triggered + an SQL query in debug mode.
