JavaScript (or Monte) Compiler for RChain

[TrenchFloat]

A compiler from monte to rholang could ease the transition from the community of programmers familiar with python and the like.

I am not really familiar with the Monte language(actually first time touch). I just check it here. So I can understand it like something which compile the Python to Rholang, right?

[dckc]

Yes, that's the idea.

[zsluedem]

That's a nice idea.
As far as I have known, there are always some limits about that kind of compiler.But still it is a good touch for understanding Rholang for Python developers.
I can help with some test once you are done.

I got it working in one case:

"feed"; "water"; "grow"

compiles to

new return in {
  new step2Ch in {
    new step1Ch in {
      step1Ch!("feed") | for(step1 <- step1Ch) {
	step2Ch!("water")
      }
    } | for(step2 <- step2Ch) {
      return!("grow")
    }
  }
}

I just (re-)discoverd section 3. INTERPRETING CAPABILITIES of Policy as Types has an example of translating javascript to a rho-calculus language. So this idea is not unprecedented. :)

I made some notes on the bibliography section of Mobile process calculi for programming the new blockchain.

Propositions as sessions by Wadler confirmed my understanding of C-H for pi calculus too. This linear logic stuff may take a little getting used to, but I'm starting to grok.

Mike Stay chatted about continuations in other languages such as JavaScript.

How would garbage collection work? How would the collector see what the closure closes over?

I just re-discovered shell-monad which reminded me that sunroof might be a good approach to rholang-to-js.
