How I normally do #async external programs in my #commonLisp image #embeddableCommonLisp and #uiop (in the notes).

Originally I was writing Kittenette (Closette but for kittens) today, but I ended up wanting to individually treat external processes, especially from #ecl on its own first.

My example is particularly using #cat(1) as an external-process in-memory echo server.

Hope it helps someone. #programming #example

Yes "multi-processing" in the url is ~erroneous.

I could not even find my own previous articles and #demos of this online!

I used #uiop run-program to handle one specific case like

(gnuplot "bad title" '((1 2) (3 4)) '((5 6) (7 8)))
or equivalently,
(apply 'gnuplot "bad title" '(((1 2) (3 4)) ((5 6) (7 8))))

Do you personally have an example? I remember it being hard to dredge up gnuplot examples but this is beyond silly.
