Minor typo in the wiki

evalExpression(str)value :

Evaluate the expression from the context of this OP. Can be used to evaluate arbitrary snippets of code from arbitrary locations.

  • str - The expression to evaluate.

op(‘wave1’).evaluateExpression(‘me.digits’) #returns 1

If the expression already resides in a parameter, use that parameters evalExpression()() method instead.

https://docs.derivative.ca/OP_Class

op(‘wave1’). evaluateExpression (‘me.digits’)

should be

op(‘wave1’). evalExpression (‘me.digits’) #returns 1
