The advantage of using JRuby is that you would get the ruby language built'in features to deal with complex data structures (like tables, matrix, multidimensional arrays...) without the need to build yet an other interpreter monster that will turn into unmaintainable and thus unmaintained code sooner than you might expect. Whether you can translate the FrAid java functions to JRuby depends on how much time you can invest. But still it might be less than adding a whole ne= w syntax + backend functions to Beanshell which is nice playing with Java syntax only. If you do so I would be very interrested in using such a language (or JRuby addon if you prefer), unfortunately I've no time to contribute those days I'm sorry. If you lack of time, sticking with FrAid might be the faster. Rapha=EBl Valyi On 11/28/06, Rapha=EBl Valyi <[email protected]> wrote: > > Hi, did you look at the FrAid java scripting language?
