## Small explanation of the mess below :)
#
# The previous version of the LaTeX formatter just assigned a command to
# each token type defined in the current style.  That obviously is
# problematic if the highlighted code is produced for a different style
# than the style commands themselves.
#
# This version works much like the HTML formatter which assigns multiple
# CSS classes to each <span> tag, from the most specific to the least
# specific token type, thus falling back to the parent token type if one
# is not defined.  Here, the classes are there too and use the same short
# forms given in token.STANDARD_TYPES.
#
# Highlighted code now only uses one custom command, which by default is
# \PY and selectable by the commandprefix option (and in addition the
# escapes \PYZat, \PYZlb and \PYZrb which haven't been renamed for
# backwards compatibility purposes).
#
# \PY has two arguments: the classes, separated by +, and the text to
# render in that style.  The classes are resolved into the respective
# style commands by magic, which serves to ignore unknown classes.
#
# The magic macros are:
# * \PY@it, \PY@bf, etc. are unconditionally wrapped around the text
#   to render in \PY@do.  Their definition determines the style.
# * \PY@reset resets \PY@it etc. to do nothing.
# * \PY@toks parses the list of classes, using magic inspired by the
#   keyval package (but modified to use plusses instead of commas
#   because fancyvrb redefines commas inside its environments).
# * \PY@tok processes one class, calling the \PY@tok@classname command
#   if it exists.
# * \PY@tok@classname sets the \PY@it etc. to reflect the chosen style
#   for its class.
# * \PY resets the style, parses the classnames and then calls \PY@do.
#
# Tip: to read this code, print it out in substituted form using e.g.
# >>> print STYLE_TEMPLATE % {'cp': 'PY'}

class LatexFormatter(Formatter):
    r"""
    Format tokens as LaTeX code. This needs the `fancyvrb` and `color`
    standard packages.

Without the `full` option, code is formatted as one ``Verbatim``
    environment, like this:

.. sourcecode:: latex

\begin{Verbatim}[commandchars=\\\{\}]
        \PY{k}{def }\PY{n+nf}{foo}(\PY{n}{bar}):
            \PY{k}{pass}
        \end{Verbatim}

Wrapping can be disabled using the `nowrap` option.

The special command used here (``\PY``) and all the other macros it needs
    are output by the `get_style_defs` method.

With the `full` option, a complete LaTeX document is output, including
    the command definitions in the preamble.

The `get_style_defs()` method of a `LatexFormatter` returns a string
    containing ``\def`` commands defining the macros needed inside the
    ``Verbatim`` environments.

Additional options accepted:

`nowrap`
        If set to ``True``, don't wrap the tokens at all, not even inside a
        ``\begin{Verbatim}`` environment. This disables most other options
        (default: ``False``).

`style`
        The style to use, can be a string or a Style subclass (default:
        ``'default'``).

`full`
        Tells the formatter to output a "full" document, i.e. a complete
        self-contained document (default: ``False``).

`title`
        If `full` is true, the title that should be used to caption the
        document (default: ``''``).

`docclass`
        If the `full` option is enabled, this is the document class to use
        (default: ``'article'``).

`preamble`
        If the `full` option is enabled, this can be further preamble commands,
        e.g. ``\usepackage`` (default: ``''``).

`linenos`
        If set to ``True``, output line numbers (default: ``False``).

`linenostart`
        The line number for the first line (default: ``1``).

`linenostep`
        If set to a number n > 1, only every nth line number is printed.

`verboptions`
        Additional options given to the Verbatim environment (see the *fancyvrb*
        docs for possible values) (default: ``''``).

`commandprefix`
        The LaTeX commands used to produce colored output are constructed
        using this prefix and some letters (default: ``'PY'``).

.. versionadded:: 0.7
        .. versionchanged:: 0.10
           The default is now ``'PY'`` instead of ``'C'``.

`texcomments`
        If set to ``True``, enables LaTeX comment lines.  That is, LaTex markup
        in comment tokens is not escaped so that LaTeX can render it (default:
        ``False``).

.. versionadded:: 1.2

`mathescape`
        If set to ``True``, enables LaTeX math mode escape in comments. That
        is, ``'$...$'`` inside a comment will trigger math mode (default:
        ``False``).

.. versionadded:: 1.2

`escapeinside`
        If set to a string of length 2, enables escaping to LaTeX. Text
        delimited by these 2 characters is read as LaTeX code and
        typeset accordingly. It has no effect in string literals. It has
        no effect in comments if `texcomments` or `mathescape` is
        set. (default: ``''``).

.. versionadded:: 2.0

`envname`
        Allows you to pick an alternative environment name replacing Verbatim.
        The alternate environment still has to support Verbatim's option syntax.
        (default: ``'Verbatim'``).
