Videos for the reactive programming language "Ceu"

Sort-of reminds me of Concurrent-C, except it doesn’t appear to directly associate data with a task, and it doesn’t appear to allow waiting on multiple events at a time (but also the runtime does more work).------------------------

nvm: no watching a later video. Basically Concurrent-C with a different syntax.------------------------

Hello Nathaniel,

  • You can wait on multiple events with a “par/or”:

par/or do
await A;
with
await B;
end

or use the sugar:

await A or B;

Lines of execution are very cheap in C?u.
We have applications with tens of them that use around 1K of RAM and 10K of
ROM (on a 16-bit platform).

  • The 3rd and 4th videos show how data can be associated with a task
    (sorry, the videos are a bit long).

  • About Concurrent-C, AFAIR, it follows a rendez-vouz asynchronous style
    (non-deterministic w/ a very different semantics).
    C?u is actually based on Esterel (a language from the 80’), with many
    differences enumerated in the previous e-mail.–

Yes, execution order was non-deterministic with Concurrent-C.

the await e1 or e2 syntax is very nice.------------------------
