Metadata-Version: 1.2 Name: colorama Version: 0.4.3 Summary: Cross-platform colored terminal text. Home-page: https://github.com/tartley/colorama Author: Jonathan Hartley Author-email: tartley@tartley.com Maintainer: Arnon Yaari License: BSD Description: .. image:: https://img.shields.io/pypi/v/colorama.svg :target: https://pypi.org/project/colorama/ :alt: Latest Version .. image:: https://img.shields.io/pypi/pyversions/colorama.svg :target: https://pypi.org/project/colorama/ :alt: Supported Python versions .. image:: https://travis-ci.org/tartley/colorama.svg?branch=master :target: https://travis-ci.org/tartley/colorama :alt: Build Status Download and docs: https://pypi.org/project/colorama/ Source code & Development: https://github.com/tartley/colorama Colorama for Enterprise: https://github.com/tartley/colorama/blob/master/ENTERPRISE.md Description =========== Makes ANSI escape character sequences (for producing colored terminal text and cursor positioning) work under MS Windows. ANSI escape character sequences have long been used to produce colored terminal text and cursor positioning on Unix and Macs. 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. Colorama also provides some shortcuts to help generate ANSI sequences but works fine in conjunction with any other ANSI sequence generation library, such as the venerable Termcolor (https://pypi.org/project/termcolor/) or the fabulous Blessings (https://pypi.org/project/blessings/). 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.init()``. 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 screengrabs show that, on Windows, Colorama does not support ANSI 'dim text'; it looks the same as 'normal text'. License ======= Copyright Jonathan Hartley & Arnon Yaari, 2013. BSD 3-Clause license; see LICENSE file. Dependencies ============ None, other than Python. Tested on Python 2.7, 3.5, 3.6, 3.7 and 3.8. Usage ===== Initialisation -------------- Applications should initialise Colorama using: .. code-block:: python from colorama import init init() On Windows, calling ``init()`` will filter ANSI escape sequences out of any text sent to ``stdout`` or ``stderr``, and replace them with equivalent Win32 calls. On other platforms, calling ``init()`` has no effect (unless you request other optional functionality; see "Init Keyword Args", below). By design, this permits applications to call ``init()`` unconditionally on all platforms, after which ANSI output should just work. 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 to calling ``init()`` again (but does the same thing). Colored Output -------------- Cross-platform printing of colored text can then be done using Colorama's constant shorthand for ANSI escape sequences: .. code-block:: python from colorama import Fore, Back, Style print(Fore.RED + 'some red text') print(Back.GREEN + 'and with a green background') print(Style.DIM + 'and in dim text') print(Style.RESET_ALL) print('back to normal now') ...or simply by manually printing ANSI sequences from your own code: .. code-block:: python print('\033[31m' + 'some red text') print('\033[39m') # and reset to default color ...or, Colorama can be used happily in conjunction with existing ANSI libraries such as Termcolor: .. code-block:: python from colorama import init from termcolor import colored # use Colorama to make Termcolor work on Windows too init() # then use Termcolor for all colored text output print(colored('Hello, World!', 'green', 'on_red')) Available formatting constants are:: Fore: BLACK, RED, GREEN, YELLOW, BLUE, MAGENTA, CYAN, WHITE, RESET. Back: BLACK, RED, GREEN, YELLOW, BLUE, MAGENTA, CYAN, WHITE, RESET. Style: DIM, NORMAL, BRIGHT, RESET_ALL ``Style.RESET_ALL`` resets foreground, background, and brightness. Colorama will perform this reset automatically on program exit. Cursor Positioning ------------------ ANSI codes to reposition the cursor are supported. See ``demos/demo06.py`` for an example of how to generate them. Init Keyword Args ----------------- ``init()`` accepts some ``**kwargs`` to override default behaviour. init(autoreset=False): If you find yourself repeatedly sending reset sequences to turn off color changes at the end of every print, then ``init(autoreset=True)`` will automate that: .. code-block:: python from colorama import init init(autoreset=True) print(Fore.RED + 'some red text') print('automatically back to default color again') init(strip=None): Pass ``True`` or ``False`` to override whether ansi codes should be stripped from the output. The default behaviour is to strip if on Windows or if output is redirected (not a tty). init(convert=None): Pass ``True`` or ``False`` to override whether to convert ANSI codes in the output into win32 calls. The default behaviour is to convert if on Windows and output is to a tty (terminal). init(wrap=True): On Windows, colorama works by replacing ``sys.stdout`` and ``sys.stderr`` with proxy objects, which override the ``.write()`` method to do their work. If this wrapping causes you problems, then this can be disabled by passing ``init(wrap=False)``. 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. To do cross-platform colored output, you can use Colorama's ``AnsiToWin32`` proxy directly: .. code-block:: python import sys from colorama import init, AnsiToWin32 init(wrap=False) stream = AnsiToWin32(sys.stderr).stream # Python 2 print >>stream, Fore.BLUE + 'blue text on stderr' # Python 3 print(Fore.BLUE + 'blue text on stderr', file=stream) Installation ======================= colorama is currently installable from PyPI: pip install colorama colorama also can be installed by the conda package manager: conda install -c anaconda colorama Status & Known Problems ======================= I've personally only tested it on Windows XP (CMD, Console2), Ubuntu (gnome-terminal, xterm), and OS X. Some presumably valid ANSI sequences aren't recognised (see details below), but to my knowledge nobody has yet complained about this. Puzzling. See outstanding issues and wishlist: https://github.com/tartley/colorama/issues If anything doesn't work for you, or doesn't do what you expected or hoped for, I'd love to hear about it on that issues list, would be delighted by patches, and would be happy to grant commit access to anyone who submits a working patch or two. Recognised ANSI Sequences ========================= ANSI sequences generally take the form: ESC [ <param> ; <param> ... <command> Where ``<param>`` is an integer, and ``<command>`` is a single letter. Zero or more params are passed to a ``<command>``. If no params are passed, it is generally synonymous with passing a single zero. No spaces exist in the sequence; they have been inserted here simply to read more easily. The only ANSI sequences that colorama converts into win32 calls are:: ESC [ 0 m # reset all (colors and brightness) ESC [ 1 m # bright ESC [ 2 m # dim (looks same as normal brightness) ESC [ 22 m # normal brightness # FOREGROUND: ESC [ 30 m # black ESC [ 31 m # red ESC [ 32 m # green ESC [ 33 m # yellow ESC [ 34 m # blue ESC [ 35 m # magenta ESC [ 36 m # cyan ESC [ 37 m # white ESC [ 39 m # reset # BACKGROUND ESC [ 40 m # black ESC [ 41 m # red ESC [ 42 m # green ESC [ 43 m # yellow ESC [ 44 m # blue ESC [ 45 m # magenta ESC [ 46 m # cyan ESC [ 47 m # white ESC [ 49 m # reset # cursor positioning ESC [ y;x H # position cursor at x across, y down ESC [ y;x f # position cursor at x across, y down ESC [ n A # move cursor n lines up ESC [ n B # move cursor n lines down ESC [ n C # move cursor n characters forward ESC [ n D # move cursor n characters backward # clear the screen ESC [ mode J # clear the screen # clear the line ESC [ mode K # clear the line Multiple numeric params to the ``'m'`` command can be combined into a single sequence:: ESC [ 36 ; 45 ; 1 m # bright cyan text on magenta background All other ANSI sequences of the form ``ESC [ <param> ; <param> ... <command>`` are silently stripped from the output on Windows. Any other form of ANSI sequence, such as single-character codes or alternative initial characters, are not recognised or stripped. It would be cool to add them though. Let me know if it would be useful for you, via the Issues on GitHub. Development =========== Help and fixes welcome! Running tests requires: - Michael Foord's ``mock`` module to be installed. - Tests are written using 2010-era updates to ``unittest`` To run tests:: python -m unittest discover -p *_test.py This, like a few other handy commands, is captured in a ``Makefile``. If you use nose to run the tests, you must pass the ``-s`` flag; otherwise, ``nosetests`` applies its own proxy to ``stdout``, which confuses the unit tests.
