[3.5.0-rc1] daemon.g keeps running after renaming

[nikscha]

Hi all,

my daemon.g looks like this:

while true          
    G4 P2000
    echo "test"

when remaning it to daemon1.g it keeps running:

changing daemon1.g to

while true             
    G4 P2000
    echo "test2"

yields

@nikscha yes it will keep running until the file terminates. In your case it never will because of the "while true" loop.

The usual solution is to use a global variable to control it:

if !exists(global.runDaemon)
  global runDaemon=true
while global.runDaemon
  ...

Then you can send set global.runDaemon=false from the console to stop the daemon.

@dc42 I see, I expected the file to be "reloaded" after saving and then not being found afterwards because of the renaming. Thank you for the solution!
