HAPedit features a multi-document interface, functions in text-mode, and uses your browser(s) to preview pages. As you write code, you can call one of the page-checking functions to check for broken links or missing images. You can extract code for images or links, to check them individually; all extractions are made after a 'compilation' for dynamic languages, such PHP or ASP. Editor shows code in text-mode, and uses your browser to preview pages. You can define several browsers, in order to check quickly display compatibilities directly from HAPedit.
