##Aims The aim of this project is to provide tools to display and edit mathematical expressions in canvas objects that work in modern browsers (IE 9+, Chrome, Safari, Firefox). Update: now works in IE8 (with font problems)

WYSIWYG editor with non-obtrusive interface. full support for cut/copy/paste within an expression and between expressions. include a parser for natural textual representation of expression very easy to include in HTML page: 3x^2 - sin theta to make an expression editable by the viewer: to allow a viewer to copy/paste (parts of) an expression: (2 sqrt x)/(1+x^2+ ln x) ##Examples Try the interactive CanvasMath playground (works in modern browsers). create, edit, copy, paste and serialize mathematical expressions.

CanvasMath can also be used to display math in a web page a bit like jsMath, except that it doesn't require latex syntax and uses canvas objects rather than html trees to display math. All that is needed is to include a javascript file in the header and to surround all math in the tag. See an example. Don't forget the view the HTML source to see how simple it is!

It will also be able to render MathML within html pages. See this MathML rendering test page. Only a small subset of Content MathML works now but it is planned that both Content and Presentation MathML will be supported.

There is also a test suite showing the input syntax and testing that it parses, renders, serializes to MathML and parses and renders MathML properly here.

##Plans It is planned that there will be a number of possible syntaxes for inputing expressions, just like there are several serializers.

##Libraries Canvasmath uses:

• jQuery for normalising events between browsers
• ExplorerCanvas to bring the canvas object to older versions of Internet Explorer
• collections.js to bring the modern iteration methods to arrays in older versions of Internet Explorer
