    Delphi Cross-Platform Application Help

    Delphi Cross-Platform Application Help

    Ziphelp is a HTML-based cross-platform application help system

    On the surface, Ziphelp is basically HTML in a compressed zip archive, hence the name. Pack any folder with HTML files into a zip archive and you are good to go. But Ziphelp is more than that, it is a protocol based on the standard sitemap protocol, designed to give a help viewer (here: the Delphi implementation) extended information about the content of the help system. That is help context numbers, help keywords, associative keywords, page titles. This information is missing in a standard sitemap.xml. Ziphelp extends the sitemap protocol and enables direct communication of an app with the help system. The Ziphelp protocol is not just for zip archives. It works inside an archive, with uncompressed folders or with HTML content loaded directly from a website. A Delphi desktop app may be deployed with local application help, uncompressed, zipped or embedded. A mobile or web application might not ship with local HTML content, but refer to an online version instead.
