Runtime binding options

[andrewfstratton]

Parameters can be bound at 3 different points:

1. Generation parameters are in the script - produce by javascript (generator.js) substitutions from go defined block definition of widgets
2. Early runtime - this is run once only when setting up the api call. e.g. a constant text to be shown or filename
3. Late runtime - this may be updated every invocation, e.g. val/txt parameters

Late runtime:

• must be only a variable, with =[a..Z][a..Z_.]*
• widget type is defined already - so variable type lookup is implicit?!

Simple option:

• separate the late runtime parameters into an overriding list of parameter=source mappings
  • i.e. mappings are split into early and late binding, e.g. media.say({early},{late})
    • e.g. media.say(speed#100,voice"female",interrupt!false,txt=txt,pitch=val)
• Note:
  -pitch widget would have a class to allow variables with number type to be dragged in.
  • txt widget would allow string variable to be dragged in

Callbacks is by using boxinput widget

A more complex example, picking at random a response, would also be a group reference, e.g.

1 pick.random(Reorder!true,Box:2)

2 media.say(Txt"Hi")
3 media.say(Txt"Hello")
4 media.say(Txt"G'day")

N.B. pick.random (Go) will reference a group array of [2,3,4] and pick randomly in that array at runtime
