MathDox formula editor
The MathDox formula editor is a web-based editor for mathematical formulas. It is currently being developed at the Technische Universiteit Eindhoven as a means for students to enter formulas in an e-learning environment. Its main features are listed below.
- It has a two-dimensional WYSIWYG interface.
- It can produce a semantic representation of the formula.
- No plugins need to be installed in the browser to use the editor.
- It can be easily integrated into existing HTML pages.
- It is available under an open source license.
Any questions or comments about the editor are welcome and can be directed at firstname.lastname@example.org.
The following formulas can be edited using your keyboard. Feel free to experiment. Supported are among others: integers, floating point numbers, variables, some keywords (like sin and pi), multiplication (*), division (/), addition (+), subtraction (-) and exponents (^).
It is possible to show zero, one or multiple palettes that can be used to insert something at the cursor position of the formulaeditor with focus. With this palette it is also possible to enter matrices and (square) roots.
To see an OpenMath representation of the first formula above click here. This demonstrates that a semantic tree of the formula is stored, and not just a presentation tree. To see a MathML representation of the first formula above click here. Note that the conversion to MathML has not been tested exhaustively and might still contain errors.
In addition you also need to add a textarea of class 'mathdoxformula' at the place where you want the formula editing field to appear:
Developers that are interested in changing the formulaeditor itself, can checkout the source from the subversion repository at:
Currently this editor is mostly tested in Mozilla Firefox (v3). It should however also work in other browsers: Microsoft Internet Explorer (v7), Safari, Opera, Konqueror.
Better documentation is needed on how to add new functions (like sin) or keywords (like pi). Furthermore it would be nice to have labels for the tabs of the palette.
