Dynamic Handling for Empirica.On

[Jeffotter]

Is there an existing issue for this?

• I have searched the existing issues

Is your feature request related to a problem?

Not really...More of an inefficiency. The issue is that one of my experimental variables is very dynamic in nature:

For example, each key I am passing could be a different capital letter of the alphabet. The problem is that in order to handle the case, my AttributeName in Empirica.on(model, attributeName, callback) would need to account for every case. (E.g 26 different letters)

Describe the solution you'd like

Ideally, I would like an option to submit one of the following:

A case function to handle multiple possible matches
An array of strings as an acceptable attribute name where each one will be checked
A third functionality where if you instead pass a variable instead of a string to attributeName this catch whatever key is set in stage.

Describe alternatives you've considered

I tried putting a list into the attribute name

I tried doing a chain of OR statements

Teachability, Documentation, Adoption, Migration Strategy

The user would in the Client call:

Stage.set('Today is ${var}', date)

On the server side:
Emprica.on("stage', NonstringVar, (ctx,{stage,NonstringVar}) =>
{ if( NonstringVar.substring(0,8) === 'Today is')

{ 
      //do specific code
} 

});
