Hello, My wife has been busy with a LMS (Claroline) and for writing down maths, there is this tool called MimeTex. http://www.forkosh.com/mimetex.html It generates images that are loaded into a page based on the Latex formula. As the whole code is a single file, this would be interesting as an equation rendering plugin for Pharo (putting that into a form or whatever). There is no need for any dependency. The easy way is to do some OSProcess magic but it has value as a plugin I think. I am working on a app on the iPad (using iOS Pharo VM + image) that has to do with formulas, so I am looking into this seriously. Question: is there anyone having done this already? No need to reinvent the wheel. Also, this coupled with a WebView could be very cool Phil
