My TiddlyWiki math project, which I'm calling Mathcell, has progressed far enough to actually be of some use to people. So I'm unleashing it on the unsuspecting public in hopes of getting some feedback and comments.
A bit of background. About the only software I use more than TiddlyWiki is Microsoft Excel. Inspired by a programming effort that created a Tiny Excel-like app in plain vanilla javascript with no libraries and just 30 lines of code, http://jsfiddle.net/ondras/hYfN3/, I set to work creating my own version. I succeeded and Mathcell (math in a cell) is the result. The essential tiddlers are about 3,000 bytes in total and there are three examples and two datatiddlers that total about another 5,000 bytes. In essence, you can enter a macrocall, <$macrocall $name="eval1" datatiddler="$:/sk/data" cell="a1"/> in any tiddler and create a Mathcell. In that Mathcell, you can enter formulas or javascript math functions and using a button toggle back and forth between the data entry form and the result. The routine can handle complex math operations, string concatenation and has circular reference protection. This routine is no match for Excel or even some of the much bigger add-in spreadsheets, but if you need some very flexible mathematics in your wiki, this may suit your needs.
