Generic
withTags :: (Tag String -> Tag String) -> String -> String Source #
Map over all tags in the document
withTagList :: ([Tag String] -> [Tag String]) -> String -> String Source #
Map over all tags (as list) in the document
Headers
demoteHeaders :: String -> String Source #
Map every h1 to an h2, h2 to h3, etc.
Url manipulation
withUrls :: (String -> String) -> String -> String Source #
Apply a function to each URL on a webpage
toUrl :: FilePath -> String Source #
Convert a filepath to an URL starting from the site root
Example:
toUrl "foo/bar.html"
Result:
"/foo/bar.html"
This also sanitizes the URL, e.g. converting spaces into '%20'
toSiteRoot :: String -> String Source #
Get the relative url to the site root, for a given (absolute) url
isExternal :: String -> Bool Source #
Check if an URL links to an external HTTP(S) source
Stripping/escaping
stripTags :: String -> String Source #
Strip all HTML tags from a string
Example:
stripTags "<p>foo</p>"
Result:
"foo"
This also works for incomplete tags
Example:
stripTags "<p>foo</p"
Result:
"foo"
escapeHtml :: String -> String Source #
HTML-escape a string
Example:
escapeHtml "Me & Dean"
Result:
"Me & Dean"
