Description

Extraction and consolidation of JavaScript code in an HTML page.

Synopsis

Simple API

consolidate :: String -> Maybe URI -> IO String Source

Takes an HTML page source as a string and an optional base URI (for resolving relative URI's) and produces an HTML page with all the scripts consolidated in one inline script element.

extract :: String -> Maybe URI -> IO (JavaScript ()) Source

Extacts all JavaScript code in the given HTML page source as a single program. Takes an optional base URI for resolving relative URI's.

extractPretty :: String -> Maybe URI -> IO String Source

Extacts and pretty-prints all JavaScript code in the given HTML page source as a single program. Takes an optional base URI for resolving relative URI's.

extractPretty s muri = liftM (show . prettyPrint) $ extract s muri

Advanced arrow-based API

type TArr a b = IOStateArrow ConsState a b Source

Our XML transformation arrow type

consolidateArr :: TArr XmlTree XmlTree Source

The consolidation function with an arrow interface.

consolidateArr = extractJSArr >>> insertJSArr

extractJSArr :: TArr XmlTree (XmlTree, JavaScript ()) Source

Extracts all JavaScript from HTML. There shouldn't be any JavaScript in the resulting XmlTree

initialConsState Source

Arguments

:: Bool

Whether to ignore errors (parse errors, resource not found etc.)

-> Maybe URI

base URI

-> [Cookie]

Cookies

-> ConsState 

A constructor function for making an initial consolidation state (needed for running the arrows in the advanced API). Example usage:

runXIOState (initialState $ initialConsState ignoreErrors muri []) $ someArrow

insertJSArr :: TArr (XmlTree, JavaScript a) XmlTree Source

Inserts JavaScript at the end of the HTML body.

parseHTML :: String -> Maybe URI -> TArr a XmlTree Source

A wrapper around the hxt parser with commonly used arguments

renderHTML :: ConsState -> TArr XmlTree XmlTree -> IO String Source

A wrapper around hxt to pretty print html out of the arrow

data ConsState Source

Consolidation state
