"""
|

|
|
Format tokens with BBcodes. These formatting codes are used by many
|
||
|
|
bulletin boards, so you can highlight your sourcecode with pygments before
|
||
|
|
posting it there.
|
||
|
|
|
||
|
|
This formatter has no support for background colors and borders, as there
|
||
|
|
are no common BBcode tags for that.
|
||
|
|
|
||
|
|
Some board systems (e.g. phpBB) don't support colors in their [code] tag,
|
||
|
|
so you can't use the highlighting together with that tag.
|
||
|
|
Text in a [code] tag usually is shown with a monospace font (which this
|
||
|
|
formatter can do with the ``monofont`` option) and no spaces (which you
|
||
|
|
need for indentation) are removed.
|
||
|
|
|
||
|
|
Additional options accepted:
|
||
|
|
|
||
|
|
`style`
|
||
|
|
The style to use, can be a string or a Style subclass (default:
|
||
|
|
``'default'``).
|
||
|
|
|
||
|
|
`codetag`
|
||
|
|
If set to true, put the output into ``[code]`` tags (default:
|
||
|
|
``false``)
|
||
|
|
|
||
|
|
`monofont`
|
||
|
|
If set to true, add a tag to show the code with a monospace font
|
||
|
|
(default: ``false``).
