CompPad is an OpenOffice extension to provide live mathematical and engineering calculations within a Writer document, allowing calculations to be documented using all of the resources of OpenOffice.CompPad will have functionality similar to Mathcad, but is not intended to be a Mathcad clone. Rather, I hope it might prove more flexible and extensible, and that it might encourage other open-source alternatives to this engineering \"Killer App.\" Compad currently exists as an \"experimental\" release, with no error handling and minimal features. Compad consists of a few Java classes, with the main method being called as a macro from within an OpenOffice document. The macro searches the document for embedded OOMath objects, translates the text of the Math object into a tokenized postfix format which is then translated into JavaScript function calls and executed in a JavaScript scripting engine. Output is posted back to the document as \"SetExpression\" text fields, which will allow full precision to be returned but display format to be controlled.Requirements:
