|

Converts a token stream to text.

Options accepted:
|
|
|
|
``style``
|
|
The style to use, can be a string or a Style subclass
|
|
(default: "default"). Not used by e.g. the
|
|
TerminalFormatter.
|
|
``full``
|
|
Tells the formatter to output a "full" document, i.e.
|
|
a complete self-contained document. This doesn't have
|
|
any effect for some formatters (default: false).
|
|
``title``
|
|
If ``full`` is true, the title that should be used to
|
|
caption the document (default: '').
|
|
``encoding``
|
|
If given, must be an encoding name. This will be used to
|
|
convert the Unicode token strings to byte strings in the
|
|
output. If it is "" or None, Unicode strings will be written
|
|
to the output file, which most file-like objects do not
|
|
support (default: None).
|
|
``outencoding``
|
|
Overrides ``encoding`` if given.
