Yesod Markdown

A small wrapper over Pandoc’s powerful Markdown -> Html support, with usage tailored for Yesod.

Usage

getPageR :: FilePath -> Handler RepHtml
getPageR fp = do
    content <- liftIO
        $ fmap markdownToHtml
        $ markdownFromFile fp

    defaultLayout $ do
        [shamlet|
            <div class="content">
                #{content}
            |]

The default extensions are minimal, you can specify you’re preferred extensions with markdownToHtmlWithExtensions:

import Text.Pandoc.Extensions (githubMarkdownExtensions)

getPageR :: FilePath -> Handler RepHtml
getPageR fp = do
    content <- liftIO
        $ fmap (markdownToHtmlWithExtensions githubMarkdownExtensions)
        $ markdownFromFile fp

    defaultLayout $ do
        [shamlet|
            <div class="content">
                #{content}
            |]
