Hi,

I have an expression like the following:

var boolStr: String = "not ((p and q) or not r)";

Here, p, q, and r are boolean variables.
Is there a method or feature like,

var bool: Boolean = parse(boolStr);

in EOL library to parse the string boolStr? How can I setup this situation?

Best regards,
Alireza

Hi Alireza,

There's no built-in support for this I'm afraid. If the strings you're interested in parsing are valid EOL expressions, I'd suggest creating a Java "tool" [1] that makes use of EolModule to parse/evaluate them.

Cheers,
Dimitris
