# Documentation

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

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' Source #

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 Source #

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 Source #

Retrieve a field value from a template context.

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

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 Source #

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 Source #

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 Source #

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

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

Produce an HTML tag with the given pandoc attributes.

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

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

htmlAlignmentToString :: Alignment -> Maybe Text Source #

Get the html representation of an alignment key

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

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

isDisplayMath :: Inline -> Bool Source #

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

fixDisplayMath :: Block -> Block Source #

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

unsmartify :: WriterOptions -> Text -> Text Source #

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

gridTable Source #

Arguments

:: Monad m |
=> WriterOptions |
-> (WriterOptions -> [Block] -> m (Doc Text)) | format Doc writer
-> [ColSpec] |
-> TableHead |
-> [TableBody] |
-> TableFoot |
-> m (Doc Text) |

Writes a grid table.

lookupMetaBool :: Text -> Meta -> Bool Source #

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

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

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

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

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

lookupMetaString :: Text -> Meta -> Text Source #

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

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

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

toSubscript :: Char -> Maybe Char Source #

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

toSuperscript :: Char -> Maybe Char Source #

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

toSubscriptInline :: Inline -> Maybe Inline Source #

toSuperscriptInline :: Inline -> Maybe Inline Source #

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

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

endsWithPlain :: [Block] -> Bool Source #

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]]]) Source #

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 Source #

ensureValidXmlIdentifiers :: Pandoc -> Pandoc Source #

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 () Source #

Set translations based on the `lang` in metadata.

isOrderedListMarker :: Text -> Bool Source #

toTaskListItem :: MonadPlus m => [Block] -> m (Bool, [Block]) Source #

delimited :: Doc Text -> Doc Text -> Doc Text -> Doc Text Source #

Add an opener and closer to a Doc. If the Doc begins or ends with whitespace, export this outside the opener or closer. This is used for formats, like Markdown, which don't allow spaces after opening or before closing delimiters.
