Hi All,
The function node below takes the path of a JavaScript file, starts
"node" (JavaScript evaluator) using "system". The output is
collected in a string.
(define (node path)
(with-output-to-string
(λ ()
(system (string-append "/usr/local/bin/node " " " (path->string
path))))))
The function is used from within DrRacket. If the JavaScript program doesn't
terminate, I use cmd-b to break the process. Control is given back to the
repl, but the node system process keeps running in the background - and
needs to be killed manually.
How can I kill the node system process from within DrRacket?
One of my attempts that didn't work:
(define (node path)
(with-output-to-string
(λ ()
(parameterize ([current-subprocess-custodian-mode 'kill]
[subprocess-group-enabled #t])
(system (string-append "/usr/local/bin/node " " "
(path->string path)))))))
