Format tokens as a raw representation for storing token streams.
|

|
|
||
|
The format is ``tokentype<TAB>repr(tokenstring)\n``. The output can later
|
||
|
be converted to a token stream with the `RawTokenLexer`, described in the
|
||
|
:doc:`lexer list <lexers>`.

|
Only two options are accepted:
|
||

`compress`
|

|
If set to ``'gz'`` or ``'bz2'``, compress the output with the given
|
||
|
compression algorithm after encoding (default: ``''``).
|
||
|
`error_color`
|
||
|
If set to a color name, highlight error tokens using that color. If
|
||
|
set but with no value, defaults to ``'red'``.
