# Documentation

metaToContext :: (Monad m, TemplateTarget a) => WriterOptions -> ([Block] -> m (Doc a)) -> ([Inline] -> m (Doc a)) -> Meta -> m (Context a) #

Create template Context from a `Meta` and an association list of variables, specified at the command line or in the writer. Variables overwrite metadata fields with the same names. If multiple variables are set with the same name, a list is assigned. Does nothing if `writerTemplate` is Nothing.

metaToContext' #

Arguments

:: (Monad m, TemplateTarget a) |
=> ([Block] -> m (Doc a)) | block writer
-> ([Inline] -> m (Doc a)) | inline writer
-> Meta |
-> m (Context a) |

Like 'metaToContext, but does not include variables and is not sensitive to `writerTemplate`.

addVariablesToContext :: TemplateTarget a => WriterOptions -> Context a -> Context a #

Add variables to a template Context, using monoidal append. Also add `meta-json`. Note that metadata values are used in template contexts only when like-named variables aren't set.

getField :: FromContext a b => Text -> Context a -> Maybe b #

Retrieve a field value from a template context.

setField :: ToContext a b => Text -> b -> Context a -> Context a #

Set a field of a template context. If the field already has a value, convert it into a list with the new value appended to the old value(s). This is a utility function to be used in preparing template contexts.

resetField :: ToContext a b => Text -> b -> Context a -> Context a #

Reset a field of a template context. If the field already has a value, the new value replaces it. This is a utility function to be used in preparing template contexts.

defField :: ToContext a b => Text -> b -> Context a -> Context a #

Set a field of a template context if it currently has no value. If it has a value, do nothing. This is a utility function to be used in preparing template contexts.

getLang :: WriterOptions -> Meta -> Maybe Text #

Get the contents of the `lang` metadata field or variable.

tagWithAttrs :: HasChars a => a -> Attr -> Doc a #

Produce an HTML tag with the given pandoc attributes.

htmlAddStyle :: (Text, Text) -> [(Text, Text)] -> [(Text, Text)] #

Adds a key-value pair to the `style` attribute.

htmlAlignmentToString :: Alignment -> Maybe Text #

Get the html representation of an alignment key

htmlAttrs :: HasChars a => Attr -> Doc a #

Produce HTML for the given pandoc attributes, to be used in HTML tags

isDisplayMath :: Inline -> Bool #

Returns `True` iff the argument is an inline `Math` element of type `DisplayMath`.

fixDisplayMath :: Block -> Block #

Put display math in its own block (for ODT/DOCX).

unsmartify :: WriterOptions -> Text -> Text #

Converts a Unicode character into the ASCII sequence used to represent the character in "smart" Markdown.

gridTable #

Arguments

:: (Monad m, HasChars a) |
=> WriterOptions |
-> (WriterOptions -> [Block] -> m (Doc a)) | format Doc writer
-> Bool | headless
-> [Alignment] | column alignments
-> [Double] | column widths
-> [[Block]] | table header row
-> [[[Block]]] | table body rows
-> m (Doc a) |

Writes a grid table.

lookupMetaBool :: Text -> Meta -> Bool #

Retrieve the metadata value for a given `key` and convert to Bool.

lookupMetaBlocks :: Text -> Meta -> [Block] #

Retrieve the metadata value for a given `key` and extract blocks.

lookupMetaInlines :: Text -> Meta -> [Inline] #

Retrieve the metadata value for a given `key` and extract inlines.

lookupMetaString :: Text -> Meta -> Text #

Retrieve the metadata value for a given `key` and convert to String.

stripLeadingTrailingSpace :: [Inline] -> [Inline] #

Remove leading and trailing `Space` and `SoftBreak` elements.

toSubscript :: Char -> Maybe Char #

Tries to convert a character into a unicode subscript version of the character.

toSuperscript :: Char -> Maybe Char #

Tries to convert a character into a unicode superscript version of the character.

toTableOfContents :: WriterOptions -> [Block] -> Block #

Construct table of contents (as a bullet list) from document body.

endsWithPlain :: [Block] -> Bool #

Returns `True` iff the list of blocks has a ``Plain`` as its last element.

toLegacyTable :: Caption -> [ColSpec] -> TableHead -> [TableBody] -> TableFoot -> ([Inline], [Alignment], [Double], [[Block]], [[[Block]]]) #

Convert the relevant components of a new-style table (with block caption, row headers, row and column spans, and so on) to those of an old-style table (inline caption, table head with one row, no foot, and so on). Cells with a `RowSpan` and `ColSpan` of `(h, w)` will be cut up into `h * w` cells of dimension `(1, 1)`, with the content placed in the upper-left corner.

splitSentences :: Doc Text -> Doc Text #

ensureValidXmlIdentifiers :: Pandoc -> Pandoc #

Ensure that all identifiers start with a letter, and modify internal links accordingly. (Yes, XML allows an underscore, but HTML 4 doesn't, so we are more conservative.)

setupTranslations :: PandocMonad m => Meta -> m () #

Set translations based on the `lang` in metadata.

isOrderedListMarker :: Text -> Bool #
