I've been toying with this idea of a,

sclang: structurred-concurency (ascii-character) language

with the purpose of visually describing, via a succinct operator-symbol-set,
various SC-supervision adhering operations that might exist in a SC system.

The high level concept is the following "axioms":

• a concurrent computing can be represented as 3 orthogonal "domains"

  • the execution domain with primitives like tasks, threads,
    processes, underpinned by CPU/GPUs..

  • the storage domain, with primitives like memory, disk-stores,
    dbs, program allocated data-structures, IPC channels/mediums,

  • a scope or context domain which combines the prior 2 in some
    way to enable a program to exist and operate with primitives
    like, cancel-scopes, nurseries, functions, namespaces..

The current and very naive WIP idea* is loosely marked up in a new
.devx.pformat.nest_from_op() helper-fn which I'd like to start using
throughout the core for various Actor.pformat()/.__repr__()
formatting which is often emitted to console via internal logging.

Detail the current ops-set with explanations?

Not sure if this something to get opinions on yet but it might be
worth scratching out in public to at least see if any lurkers think
the entire concept is a bit.. redic?

XD

TODO: some pretty-formatting to try throughout?

I figure (and since i've already started, lel) might as well try this
idea in various primitives and see how it goes, who does[n't] like
it.

• make all the .__repr__()s for various runtime primitives look real nice (and correct)
  even when we use our little "sclang" (see the strange long
  comment i put in ._child.nest_from_op() XD) ascii-syntax for
  conveying various states!
  • Actor
    • the |_state: runtime-state field section needs work..
  • Channel
  • MsgTransport
  • IPCServer
    • needs a nest_from_op() to mk it pretty inside Actor.pformat()
  • IPCEndpoint
    • fix the indentation and field deats on
      IPCServer.pformat() (namely adopting the
      .devx.pformat.nest_from_op() and similar other primitives
      fmt/styling).
