Basic Usage: >>> code = CodeHilite(src = 'some text') >>> html = code.hilite() * src: Source string or any object with a .readline attribute. * linenums: (Boolean) Set line numbering to 'on' (True), 'off' (False) or 'auto'(None). Set to 'auto' by default. * guess_lang: (Boolean) Turn language auto-detection 'on' or 'off' (on by default). * css_class: Set class name of wrapper div ('codehilite' by default). * hl_lines: (List of integers) Lines to emphasize, 1-indexed.

If the sheband line contains a path (even a single /) then it is assumed to be a real shebang line and left alone. However, if no path is given (e.i.: #!python or :::python) then it is assumed to be a mock shebang for language identifitation of a code fragment and removed from the code block prior to processing for code highlighting. When a mock shebang (e.i: #!python) is found, line numbering is turned on. When colons are found in place of a shebang (e.i.: :::python), line numbering is left in the current state - off by default. Also parses optional list of highlight lines, like: :::python hl_lines="1 3" rNr&a (?:(?:^::+)|(?P^[#]!)) # Shebang or 2 or more colons (?P(?:/\w+)*[/ ])? # Zero or 1 path (?P[\w#.+-]*) # The language \s* # Arbitrary whitespace # Optional highlight lines, single- or double-quote-delimited (hl_lines=(?P"|')(?P.*?)(?P=quot))? rpathZshebangTr")rerrpopcompileVERBOSEsearchgrouplowerr IndexErrorinsertrrr"r6r1)r$r:linesZflcmrrrr2s&       zCodeHilite._parseHeader) NNTrNrFrNT)__name__ __module__ __qualname____doc__r%r8r2rrrrr0s 3rc@s eZdZdZddZddZdS)HiliteTreeprocessorz% Hilight source code in code blocks. cCs(|dd}|dd}|dd}|S)zUnescape code.r)r(r+r*r-r,)r4)r$r'rrr code_unescapes   z!HiliteTreeprocessor.code_unescapec Cs|d}|D]}t|dkr|djdkrt||dj|jd|jd|jd|jd|jd |jj|jd d }|jj | }| d |_||_qd S)z* Find code blocks and store in htmlStash.
