scripting-go

This package is used to evaluate expressions written in NCScript format. In the current state it is only meant to evaluate simple expressions and not able to parse full NCScripts since it is not necessary for the current application.

Usage

parsing expressions

You can parse expressions by calling

expression,err:=scripts.Parse(<expression as string>)

err then will contain any parsing errors. If err is anything but nil you can assume expression not to contain anything useful. When err is nil however you can then evaluate the expression by calling

result,err:=expression.Execute(<variables>)

Again err will contain any evaluation errors. If everything went well with evaluating the expression, result contains the evaluation result. You can specify if you used any variables in the given expression. If you used variables in the expression and don't specify them here the evaluation automatically results in an error since the variable value can't get resolved.
