Velocity is a template language developed by Java, primarily for dynamic web content. Although it has been depreciated since 2021, documentation and source code is available at the time of this writing (November 2023).
The language itself is similiar in some respects to BASIC but also has some similiarities to it's parent, Java.
This guide focuses on how Velocity applies towards writing Newlife content and assumes that you have a general working knowledge of programming (You understand what conditionals are, you understand what a loop is, and so forth). It does not assume that you know Velocity or Java.
// overview of Velocity, touching on macros, derectives, data types, conditionals, loops... the basics // this is primarily in case Apache's reference goes dark at some future point
// data types should also show the internal class names (that you can check against using the .class property) // the concept of casting should probably be touched upon.
// This section will go over tricks and tips and also how to deal with some of Velocity's many idiosyncrasies
// code examples
