One idea we discussed is to "compile" Nasal into Javascript and send it to the browser (together with the canvas as SVG), but we don't know yet if this is possible with a reasonable effort. Also we should ensure that the JavaScript API and Nasal API are identical, such the code can be easily converted/ported. So we need to define a safe subset of Nasal and JavaScript and come up with corresponding classes to wrap identical stuff. And there are a quite a few useful JS features that Nasal will never support, so we need to use factories for those to hide differences between both languages (sounds like something that Philosopher might enjoy), or someone will end up complaining that jQuery breaks Nasal... | One idea we discussed is to "compile" Nasal into Javascript and send it to the browser (together with the canvas as SVG), but we don't know yet if this is possible with a reasonable effort.
