Why do many and at_least_one return void while consume, subrule, or, and option return values?

Shouldn't they return arrays?

I'll note the example embedded actions parser manipulates a captured result value in the body of the function passed to MANY, instead of using a value returned from MANY. Plus it is impossible to pass arguments to the function called by MANY. Together, this makes it impossible to construct the rule bottom-up, as I'm trying to do.

Hello @thejohnfreeman

History for that decision can be found here:

• Remove automatic collection of return values for iterations #784

I think you may be able implement this yourself:

class MyParser extends EmbeddedActionsParser {
   
   // you could decide to always pass a subRule rather than a general grammar action and that would guarantee 
   // something would be returned on each iteration
    myMany(idx, iterationAction) {
         const resultArr = []
         this.many(idx, () => {
             const iterItem = iterationAction() // may need to bind to the parser's `this` when invoking...
             resultArr.push(iterItem)
         })
         return resultArr
    }
}
