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 (http://pypi.python.org/pypi/termcolor) + or the fabulous Blessings (https://pypi.python.org/pypi/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 2013. BSD 3-Clause license; see LICENSE file. + + + Dependencies + ============ + + None, other than Python. Tested on Python 2.5.5, 2.6.5, 2.7, 3.1.2, 3.2, 3.3, + 3.4 and 3.5. + + 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[30m') # 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) + + + 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 [ ; ... + + Where ```` is an integer, and ```` is a single letter. Zero or + more params are passed to a ````. 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 [ ; ... `` + 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.
