You're having a case of wrong functional scope here.. :-) Let me explain:
{true} is a shortcut for the simply function fun () -> true, i.e. a
function that takes no argument and always returns true.
Now, in the code above, the body of your function is only executed
once, at startup, and returns either {true} or {false}.
This means that your switching function will be fixed and one of
{true} or {false} during the execution of the script, which is not
what you want to..
Instead, you just need to change the scope of your function as follows:
def stop_after_current() =
raw_output = get_process_lines("./stop_after_current.py")
stop = list.hd(raw_output)
if stop == "true" then
false
else
true
end
end
Do you see the difference?
Hope this helps!
