## Styles

« Back To Index

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:

    >>> 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:

    >>> 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 pygments.style.Style) and pass it to the formatter:

    >>> 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:

    from pygments.style 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)
- 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 `mondrian.py` and this file into the `pygments.styles` subpackage directory.

### Style Rules

Here a small overview of all allowed styles:

`bold`
  render text as bold
`nobold`
  don't render text as bold (to prevent subtokens behing highlighted bold)
`italic`
  render text italic
`noitalic`
  don't render text as italic
`underline`
  render text underlined
`nounderline`
  don't render text underlined
`bg:`
  transparent background
`bg:#000000`
  background color (black)
`border:`
  no border
`border:#ffffff`
  border color (white)
`#ff0000`
  text color (red)
`noinherit`
  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:

    >>> 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:

    >>> from pygments.styles import get_all_styles
    >>> styles = list(get_all_styles())
