// <nowiki>
// Wiki user script to help maintain {{family *tree}},{{chart}} or {{tree chart}}
// boxes-and-lines diagrams, by allowing you to edit the diagram
// in a simpler and more standard ASCII art format.
// Greg Ubben, 1 Dec 2008
// User:PBS , 31 Jan 2020 added code to parse "family tree" and "tree chart"
//
// To install, add: importScript("User:Daduxing/familytree.js");
// to your common.js page. This adds an option [Templates → Art]
// to the toolbox menu when editing familytrees.
//
// It is a two pass operation.
// 1. Press [Templates → Art] -- the template code is changed into an intermediate
// format and the menu option changes to [Art → Templates]
// 2. Press Art → Templates] -- converts the "Art" back in to cleaned up temlate code
//
//
// IE may work better than Firefox since it supports typeover mode.
//
// TODO:
// - Anything we can do to improve [[WP:ACCESSIBILITY]]
// - Some smarts with border/boxstyle
//
// Advanced ideas:
// - Draw line between start and end of selection
// - Cut/copy/paste rectangular selections (no existing library??)
// - include overwrite/typeover mode emulation for Firefox
// - Java GUI version where you drag boxes and lines on a grid
