Text.Pandoc.Builder

Contents

Description

Convenience functions for building pandoc documents programmatically.

Example of use (with OverloadedStrings pragma):

import Text.Pandoc.Builder

myDoc :: Pandoc
myDoc = setTitle "My title" $ doc $
  para "This is the first paragraph" <>
  para ("And " <> emph "another" <> ".") <>
  bulletList [ para "item one" <> para "continuation"
             , plain ("item two and a " <>
                 link "/url" "go to url" "link")
             ]

Isn't that nicer than writing the following?

import Text.Pandoc.Definition
import Data.Map (fromList)

myDoc :: Pandoc
myDoc = Pandoc (Meta {unMeta = fromList [("title",
          MetaInlines [Str "My",Space,Str "title"])]})
        [Para [Str "This",Space,Str "is",Space,Str "the",Space,Str "first",
         Space,Str "paragraph"],Para [Str "And",Space,Emph [Str "another"],
         Str "."]
        ,BulletList [
          [Para [Str "item",Space,Str "one"]
          ,Para [Str "continuation"]]
         ,[Plain [Str "item",Space,Str "two",Space,Str "and",Space,
                  Str "a",Space,Link [Str "link"] ("/url","go to url")]]]]

And of course, you can use Haskell to define your own builders:

import Text.Pandoc.Builder
import Text.JSON
import Control.Arrow ((***))
import Data.Monoid (mempty)

-- | Converts a JSON document into 'Blocks'.
json :: String -> Blocks
json x =
  case decode x of
       Ok y    -> jsValueToBlocks y
       Error y -> error y
   where jsValueToBlocks x =
          case x of
           JSNull         -> mempty
           JSBool x       -> plain $ text $ show x
           JSRational _ x -> plain $ text $ show x
           JSString x     -> plain $ text $ fromJSString x
           JSArray xs     -> bulletList $ map jsValueToBlocks xs
           JSObject x     -> definitionList $
                              map (text *** (:[]) . jsValueToBlocks) $
                              fromJSObject x
