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} 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: `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'``). .. versionadded:: 2.0 �LaTeX�latex�texz*.texc K s� t j| fi |�� |�dd�| _|�dd�| _t|dd�| _tt|dd��| _ tt|d d��| _ |�d d�| _ t|d d�| _ |�d d �| _ t|dd�| _t|dd�| _|�dd�| _t| j�dkrn| jd | _| jd | _nd| _|�dd�| _| �� d S )N�docclass�article�preambler# �linenosF� linenostart� � linenostep� verboptions� nobackgroundr �PY� texcomments� mathescape� escapeinside� r �envname�Verbatim)r �__init__r% r. r0 r r1 �absr r2 r4 r5 r6 r r8 r9 r: �len�left�rightr< �_create_stylesheet)�self�optionsr r r! r> � s$ zLatexFormatter.__init__c C s. t di }| _i }| _| j}dd� }| jD ]~\}}t|�}d}|d r(|d7 }|d r0|d7 }|d r8|d 7 }|d r@|d 7 }|d rH|d 7 }|d rP|d 7 }|d r^|d||d � 7 }|d rs|d||d �||d �f 7 }n|d r�|d||d � 7 }|dkr�q|�d|�}|||< |||< qd S )Nr# c s � rd� � fdd�dD ��S dS )N�,c s. g | ]}d t � | � |d d�d �qS )z%.2fr3 � g �o@)�int)�.0�i��colr r! � <listcomp> s &�zGLatexFormatter._create_stylesheet.<locals>.rgbcolor.<locals>.<listcomp>)r r; � z1,1,1)�joinrK r rK r! �rgbcolor s �z3LatexFormatter._create_stylesheet.<locals>.rgbcolor�boldz\let\$$@bf=\textbf�italicz\let\$$@it=\textit� underlinez\let\$$@ul=\underline�romanz\let\$$@ff=\textrm�sansz\let\$$@ff=\textsf�mono�colorz'\def\$$@tc##1{\textcolor[rgb]{%s}{##1}}�borderz\\def\$$@bc##1{{\setlength{\fboxsep}{\string -\fboxrule}\fcolorbox[rgb]{%s}{%s}{\strut ##1}}}�bgcolorzH\def\$$@bc##1{{\setlength{\fboxsep}{0pt}\colorbox[rgb]{%s}{\strut ##1}}}z$$)r � ttype2name�cmd2defr �styler* r ) rD �t2n�c2d�cprP r' �ndef�name�cmndefr r r! rC sN � �� � �z!LatexFormatter._create_stylesheetr# c C sH | j }g }| j�� D ]\}}|�d|||f � q t| j d�|�d� S )z� Return the command sequences needed to define the commands used to format text in the verbatim environment. ``arg`` is ignored. z\@namedef{%s@tok@%s}{%s}� )r_ �styles)r r[ �items�append�STYLE_TEMPLATErO )rD �argr_ rd ra � definitionr r r! �get_style_defs< s �z LatexFormatter.get_style_defsc C sj | j }| j}| jr|}t� }|�d| j d � | jr7| j| j}}|�d|r+d| p,d |r3d| p4d � | j s@| j s@| j rE|�d� | j rP|�d| j � |�d � |D �] \}} |t jv �r| j r�| d d � }td t| ��D ]} |d | | kr~ n|| | 7 }qr| t|�d � } t||�}|| } nu| j r�| �d �} d } t| �D ]\} } | s�t| |�| | < | } q�d �| �} nP| j r�| }d} |r�|�| j�\}}}|r�|�| j�\}}}|r�| t||�| 7 } n| t|| | |�7 } n| t||�7 } |s�nt| |�} n |t jv�r t| |�} g }|t u�r6z |�|| � W n t�y- |�t|�� Y nw |j }|t u�sd�t |��}|�rs| �d�}|d d� D ]}|�rZ|�d|||f � |�d� �qK|d �rr|�d|||d f � qW|�| � qW|�d| j d � | j�r�| j �p�d}dddd�� |� dd�|�}|�t!t"| j#| j$| j%|| �&� |�'� d� � d S d S )Nz\begin{z}[commandchars=\\\{\}z ,numbers=leftz,firstnumber=%dr# z,stepnumber=%dz6,codes={\catcode`\$=3\catcode`\^=7\catcode`\_=8\relax}rF z] r r3 r F�+rc r$ z \%s{%s}{%s}z\end{z} �utf8�latin1)�utf_8�latin_1� iso_8859_1r r )r. r0 �title�encoding� styledefs�code)(rZ r �fullr �writer< r1 r2 r4 r9 r8 r: r5 r �Comment�ranger@ r" �split� enumeraterO � partitionrA rB �Escaperf �KeyErrorr* r& �reversedrr r% r � DOC_TEMPLATE�dictr. r0 rq rj �getvalue)rD � tokensource�outfiler] r_ � realoutfile�start�stepr' �valuerJ �parts�in_math�partr �a�sep1�b�sep2rd �styleval�spl�linerr r r r! �format_unencodedH s� �� �� � � � ��� ��z LatexFormatter.format_unencodedN)r# ) �__name__� __module__� __qualname__�__doc__ra �aliases� filenamesr> rC rj r� r r r r! r � s a - c @ s8 e Zd ZdZdd� Zdd� Zdd� Zdd � Zd d � Zd S ) �LatexEmbeddedLexera� This lexer takes one lexer as argument, the lexer for the language being formatted, and the left and right delimiters for escaped text.
