Moodle DragMath README

Package Integration:

In order to make DragMath installation for Moodle users as simple as possible, the DragMath package (see README.html has been integrated with Moodle and a zip created so that the user can simply place the new zip in their Moodle root and unzip (no file shifting necessary). To accomodate this installation method a replacement for the file adminlib.php is not provided, though /lib/adminlib_exampleonly.php has been provided so that you can compare this version to your own version so as to make the quick line change in your own adinlib.php to allow you to hide the dragmath icon (by adding the icon to the adminlib.php icon array for the GUI.

The package include some changes, including but not limited to:

Moving the DragMath directory to /lib/DragMath - it was thought that with changes to the actual DragMath infrastructure, leaving DragMath in its previous location might result in more confusion that start9ing afresh, and /lib/DragMath is the location where DragMath will be found in Moodle 2.
Adding a language variable in dlg_ins_dragmath.php so that DragMath will, to the extent of its own language files, use the same language as set in Moodle.
Change the reference to codebase in the applet in dlg_ins_dragmath.php so that it is relative to Moodle root and can be changed to pass different locations
Employing the new Moodle DragMath icon presently adopted for Moodle 2 (the old icon is still present, and you need only change file names in the /lib/editor/htmlarea/images directory to revert.
And, of course, addressing all the changes made to DragMath bu its authors

Since the zip created will install on unzip, this file is located in the DragMath directory so that /lib is not populated with install READMEs. Once installed, you should be able to update to future version of DragMath simply by replacing the current /lib/DragMath with the DragMath folder available on sourceforge; the integration will not change.

The integration files are located in /lib/editor/htmlarea/ and include a replacement dialog.js, a replacement htmlarea.php, a new popups/dlg_ins_dragmath.php, and three icons in images/. Only dlg_ins_dragmath.php has been altered for this version.

Credit for making the integration possible goes of course to Chris, Alex and the DragMath folks as well as to Mauno Korpelainen

NB: There has been discussion that a line in dialog.js has produced some problems in Moodle version 1.9.5+ (the editor disappears) and that by deleting the line that adds the dragmath icon the problem is resolved. This may be an artifact of the impact of the icon sizing, so if you discover such a situation please post at once to the Math Tools forum on Moodle.org so that the situation can be fully documented and resolved.
