We have an application that allows users to enter conditionals in the form bound op x op bound2, we store this as a string, and then parse it at runtime to evaluate it.It is a decent amount of work, for a very limited conditional statement.We are looking for a way to serialize and then evaluate complex conditions, with at least a switch statement level of complexity.I saw in this question How to serialize and deserialize lambda expression in F#? that in f# you can just serialize a lambda (and I assume that there is some way to get a lambda from a text string), but:We need to do this in JavaI know that we can compile java code on the fly, and make it safe by stripping out keywords, and disallowing things like System. but even if its not a security nightmare, it is prohibitively computationally expensive to do thousands of times.Does anyone know of a small language out there whose interpreter can do just the basics (conditionals, loops, variable assignment) and be run in/as java, or any way to run those types of expression as they are defined at runtime and need to be persisted.Update: To be clear, the minimum functionality I need is an if else chain. I don't just need to evaluate one condition. The one condition is what I have now already.
