Expose TesterOptions / getTestOptions to programmatically set options about chiseltest HOT 5 CLOSED

I need it for not use sbt and need command line options exposed some other way and layer on top of testers2 that propagates the vcd dump switch from higher [up in a flow].

I'm willing to accept breakage and it's totally cool if it's not the final API. I'd rather help test testers2 than go back to testers1 especially for a new project...

@edwardcwang in what way is TesterOptions private? It should be easy to read and/or write them as necessary

@edwardcwang can you give me an example use case? My thoughts are that things done in code are more permanent, while command-line operations are for temporary debugging flags like VCD dump.

If there is a reasonable use case I can open it up as an experimental API. Exposing options in a stable form is probably going to be very tricky.

TesterOptions is declared private[tester] case class TesterOptions so I can't use it directly from user code.

I want to be able to do something like

class MyTestSpec extends FlatSpec with ChiselScalatestTester with Matchers {
  override def getTestOptions: TesterOptions = {
    val test = scalaTestContext.value.get
    TesterOptions(test.name, writeVcd=<programmatically set VCD dumping>)
  }
  // rest of tests...
}

or even as an optional parameter to test() is fine as well, just some way I can set the settings

Yes, I understand that, but why doesn't command line options meet your use case? Do you want to dump VCDs for all runs (instead of only temporarily during debugging - and is this for all tests, or just a few)? Do you not use sbt and need command line options exposed some other way? Do you have a layer on top of testers2 that propagates the vcd dump switch from higher?

You're asking for a mechanism - and a really general / powerful one that is likely to be unstable. I want to be a bit more confident that this is the right mechanism, not just the one that appears most convenient right now.
