Styles
======
Pygments comes with :doc:`some builtin styles </styles/>` that work for both the
HTML and LaTeX formatter.
The builtin styles can be looked up with the `get_style_by_name` function:
.. sourcecode:: pycon
>>> from pygments.styles import get_style_by_name
>>> get_style_by_name('colorful')
<class 'pygments.styles.colorful.ColorfulStyle'>
You can pass a instance of a `Style` class to a formatter as the `style`
option in form of a string:
.. sourcecode:: pycon
>>> from pygments.styles import get_style_by_name
>>> from pygments.formatters import HtmlFormatter
>>> HtmlFormatter(style='colorful').style
<class 'pygments.styles.colorful.ColorfulStyle'>
Or you can also import your own style (which must be a subclass of
`pygments.style.Style`) and pass it to the formatter:
.. sourcecode:: pycon
>>> from yourapp.yourmodule import YourStyle
>>> from pygments.formatters import HtmlFormatter
>>> HtmlFormatter(style=YourStyle).style
<class 'yourapp.yourmodule.YourStyle'>
Creating Own Styles
===================
See :ref:`creating-own-styles`.
Builtin Styles
==============
Pygments ships some builtin styles which are maintained by the Pygments team.
To get a list of known styles you can use this snippet:
.. sourcecode:: pycon
>>> from pygments.styles import STYLE_MAP
>>> STYLE_MAP.keys()
['default', 'emacs', 'friendly', 'colorful']
Getting a list of available styles
==================================
.. versionadded:: 0.6
Because it could be that a plugin registered a style, there is
a way to iterate over all styles:
.. sourcecode:: pycon
>>> from pygments.styles import get_all_styles
>>> styles = list(get_all_styles())
.. _AnsiTerminalStyle:
Terminal Styles
===============
.. versionadded:: 2.2
Custom styles used with the 256-color terminal formatter can also map colors to
use the 8 default ANSI colors. To do so, use ``ansigreen``, ``ansibrightred`` or
any other colors defined in :attr:`pygments.style.ansicolors`. Foreground ANSI
colors will be mapped to the corresponding `escape codes 30 to 37
<https://en.wikipedia.org/wiki/ANSI_escape_code#Colors>`_ thus respecting any
custom color mapping and themes provided by many terminal emulators. Light
variants are treated as foreground color with and an added bold flag.
``bg:ansi<color>`` will also be respected, except the light variant will be the
same shade as their dark variant.
See the following example where the color of the string ``"hello world"`` is
governed by the escape sequence ``\x1b[34;01m`` (Ansi bright blue, Bold, 41 being red
background) instead of an extended foreground & background color.
.. sourcecode:: pycon
>>> from pygments import highlight
>>> from pygments.style import Style
>>> from pygments.token import Token
>>> from pygments.lexers import Python3Lexer
>>> from pygments.formatters import Terminal256Formatter
>>> class MyStyle(Style):
styles = {
Token.String: 'ansibrightblue bg:ansibrightred',
}
>>> code = 'print("Hello World")'
>>> result = highlight(code, Python3Lexer(), Terminal256Formatter(style=MyStyle))
>>> print(result.encode())
b'\x1b[34;41;01m"\x1b[39;49;00m\x1b[34;41;01mHello World\x1b[39;49;00m\x1b b'\x1b[34;41;01m"\x1b[39;49;00m\x1b[34;41;01mHello World\x1b[39;49;00m\x1b[34;41;01m"\x1b[39;49;00m'
Colors specified using ``ansi*`` are converted to a default set of RGB colors
when used with formatters other than the terminal-256 formatter.
By definition of ANSI, the following colors are considered "light" colors, and
will be rendered by most terminals as bold:
- "brightblack" (darkgrey), "brightred", "brightgreen", "brightyellow", "brightblue",
"brightmagenta", "brightcyan", "white"
The following are considered "dark" colors and will be rendered as non-bold:
- "black", "red", "green", "yellow", "blue", "magenta", "cyan",
"gray"
Exact behavior might depends on the terminal emulator you are using, and its
settings.
.. _new-ansi-color-names:
.. versionchanged:: 2.4
The definition of the ANSI color names has changed.
New names are easier to understand and align to the colors used in other projects.
===================== ====================
New names Pygments up to 2.3
===================== ====================
``ansiblack`` ``#ansiblack``
``ansired`` ``#ansidarkred``
``ansigreen`` ``#ansidarkgreen``
``ansiyellow`` ``#ansibrown``
``ansiblue`` ``#ansidarkblue``
``ansimagenta`` ``#ansipurple``
``ansicyan`` ``#ansiteal``
``ansigray`` ``#ansilightgray``
``ansibrightblack`` ``#ansidarkgray``
``ansibrightred`` ``#ansired``
``ansibrightgreen`` ``#ansigreen``
``ansibrightyellow`` ``#ansiyellow``
``ansibrightblue`` ``#ansiblue``
``ansibrightmagenta`` ``#ansifuchsia``
``ansibrightcyan`` ``#ansiturquoise``
``ansiwhite`` ``#ansiwhite``
===================== ====================
Old ANSI color names are deprecated but will still work.
