REPL for SPIN2?

in Propeller 2
The recent JavaScript discussion, which also mentioned environments like Lua and Python, touched on their REPL capabilities. It occurs to me that this might a good thing for SPIN2 to support. From an educational perspective, I find REPL to be extremely handy for experimentation and learning.

    There already is a mature REPL...it's called Tachyon2!!

    Using Propeller-OSes like Sphinx and Spinix (some others too), you can run a SPIN compiler on the Propeller1.

    That's not really a SPIN REPL but a step into the direction of a self hosted SPIN based system...

    Tachyon2 is SPIN?

    Spin is not REPL but Tachyon is, but more correctly it Reads, Compiles, Executes, Loop, so it is more of a RCEL as that whole EVAL PRINT thing is a bit of an over simplification.

    Here is some simple Tachyon for the P2 (TF2) console "REPL"

    The question definitely was for a SPIN REPL.

    Why do Forthers always jump into non Forth threads advertising Forth?

    That's annoying!

    I want a Forth ad-blocker...

    Why are you being so rude, I simply answered your (first) question in line with the OP's statement " I find REPL to be extremely handy for experimentation and learning. " and the reply by mindrobots.

    Anyway, there is no such thing as a "Forther" as if it is about "us" and "them". Forth is a tool that is available, why would I try to hammer a screw in because I hate "drillers"? Just use the best tool available.

    Peter has also talked about being able to support Spin syntax on top of the Tachyon VM. That would for all practical purposes give you a Spin REPL rather quickly.

    Sorry you got up on the wrong side of the bed today. Forums seem to be a silly thing to get upset about these days with everything else going on.
