Arguments

:: SyntaxMap

-> (FormatOptions -> [SourceLine] -> a)

Formatter

-> Attr

Attributes of the CodeBlock

-> Text

Raw contents of the CodeBlock

-> Either Text a

formatLaTeXInline :: FormatOptions -> [SourceLine] -> Text

Formats tokens as LaTeX using custom commands inside | characters. Assumes that | is defined as a short verbatim command by the macros produced by styleToLaTeX. A KeywordTok is rendered using \KeywordTok{..}, and so on.

formatLaTeXBlock :: FormatOptions -> [SourceLine] -> Text

Format tokens as a LaTeX Highlighting environment inside a Shaded environment. Highlighting and Shaded are defined by the macros produced by styleToLaTeX. Highlighting is a verbatim environment using fancyvrb; \, {, and } have their normal meanings inside this environment, so that formatting commands work. Shaded is either nothing (if the style's background color is default) or a snugshade environment from framed, providing a background color for the whole code block, even if it spans multiple pages.

styleToLaTeX :: Style -> Text

Converts a Style to a set of LaTeX macro definitions, which should be placed in the document's preamble. Note: default LaTeX setup doesn't allow boldface typewriter font. To make boldface work in styles, you need to use a different typewriter font. This will work for computer modern:

\DeclareFontShape{OT1}{cmtt}{bx}{n}{<5><6><7><8><9><10><10.95><12><14.4><17.28><20.74><24.88>cmttb10}{}

Or, with xelatex:

\usepackage{fontspec}
\setmainfont[SmallCapsFont={* Caps}]{Latin Modern Roman}
\setsansfont{Latin Modern Sans}
\setmonofont[SmallCapsFont={Latin Modern Mono Caps}]{Latin Modern Mono Light}

formatHtmlInline :: FormatOptions -> [SourceLine] -> Html

Format tokens using HTML spans inside code tags. For example, A KeywordTok is rendered as a span with class kw. Short class names correspond to TokenTypes as follows: KeywordTok = kw, DataTypeTok = dt, DecValTok = dv, BaseNTok = bn, FloatTok = fl, CharTok = ch, StringTok = st, CommentTok = co, OtherTok = ot, AlertTok = al, FunctionTok = fu, RegionMarkerTok = re, ErrorTok = er, ConstantTok = cn, SpecialCharTok = sc, VerbatimStringTok = vs, SpecialStringTok = ss, ImportTok = im, DocumentationTok = do, AnnotationTok = an, CommentVarTok = cv, VariableTok = va, ControlFlowTok = cf, OperatorTok = op, BuiltInTok = bu, ExtensionTok = ex, PreprocessorTok = pp, AttributeTok = at, InformationTok = in, WarningTok = wa. A NormalTok is not marked up at all.

formatHtmlBlock :: FormatOptions -> [SourceLine] -> Html

Format tokens as an HTML pre block. Each line is wrapped in an a element with the class ‘source-line’. If line numbering is selected, the surrounding pre is given the class ‘numberSource’, and the resulting html will display line numbers thanks to the included CSS. See the documentation for formatHtmlInline for information about how tokens are encoded.

styleToCss :: Style -> String

Returns CSS for styling highlighted code according to the given style.

pygments :: Style

Style based on pygments's default colors.

espresso :: Style

Style based on ultraviolet's espresso_libre.css (dark background).

zenburn :: Style

Style based on the popular zenburn vim color scheme

tango :: Style

Style based on pygments's tango colors.

kate :: Style

Style based on kate's default colors.

monochrome :: Style

Style with no colors.

breezeDark :: Style

Style from the breeze-dark KDE syntax highlighting theme.

haddock :: Style

Style based on haddock's source highlighting.

data Style

A rendering style. This determines how each kind of token is to be rendered, and sets a default color and background color for normal tokens. Line numbers can have a different color and background color.
