// // Wiki user script to help maintain, or // 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
