Pygments comes with some builtin 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
    >>> HtmlFormatter(style='colorful').style
    <class 'pygments.styles.colorful.ColorfulStyle'>

Or you can also import your own style (which must be a subclass of
``) and pass it to the formatter:

.. sourcecode:: pycon

    >>> from yourapp.yourmodule import YourStyle
    >>> HtmlFormatter(style=YourStyle).style
    <class 'yourapp.yourmodule.YourStyle'>

Creating Own Styles

So, how to create a style? All you have to do is to subclass `Style` and
define some styles:

.. sourcecode:: python

    from import Style
    from pygments.token import Keyword, Name, Comment, String, Error, \
         Number, Operator, Generic

    class YourStyle(Style):
        default_style = ""
        styles = {
            Comment:                'italic #888',
            Keyword:                'bold #005',
            Name:                   '#f00',
            Name.Function:          '#0f0',
            Name.Class:             'bold #0f0',
            String:                 'bg:#eee #111'

That's it. There are just a few rules. When you define a style for `Name`
the style automatically also affects `Name.Function` and so on. If you
defined ``'bold'`` and you don't want boldface for a subtoken use ``'nobold'``.

(Philosophy: the styles aren't written in CSS syntax since this way
they can be used for a variety of formatters.)

`default_style` is the style inherited by all token types.

To make the style usable for Pygments, you must

* either register it as a plugin (see `the plugin docs <plugins.txt>`_)
* or drop it into the `styles` subpackage of your Pygments distribution one style
  class per style, where the file name is the style name and the class name is
  `StylenameClass`. For example, if your style should be called
  ``"mondrian"``, name the class `MondrianStyle`, put it into the file
  ```` and this file into the ``pygments.styles`` subpackage

Style Rules

Here a small overview of all allowed styles:

    render text as bold
    don't render text as bold (to prevent subtokens behing highlighted bold)
    render text italic
    don't render text as italic
    render text underlined
    don't render text underlined
    transparent background
    background color (black)
    no border
    border color (white)
    text color (red)
    don't inherit styles from supertoken

Note that there may not be a space between ``bg:`` and the color value
since the style definition string is split at whitespace.
Also, using named colors is not allowed since the supported color names
vary for different formatters.

Furthermore, not all lexers might support every style.

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

*New in Pygments 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())
