meditor Jolly (2025) is a text-based editor interface to the Java symbolic computing engine/library (JSCL). It operates as a magic board: expressions are evaluated in-place and rendered, either in text or MathML. Communication with the engine is made through the JSR-223 Scripting API, which makes it interchangeable. MathML results are integrated in the document as MathML islands. It is also possible to include graphs as SVG islands. With this technique, the file format is restricted to text/plain, for improved interoperability. There is however the option to export documents in XHTML and PDF. MathML fragments are translated to script using XSLT transformations, to be interpreted again by the engine. The symbolic engine can be either specialized for symbolic computation, or a general purpose scripting language, following the "libraries and scripting" approach Jolly and Kredel (2008), which will be showcased using the Beanshell scripting language Niemeyer (1997).
Raphaël Jolly (Mon,) studied this question.
