Dancer2 start/stop hooks

morgon has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

is there any hook or callback that would allow one to trigger some action whenever dancer starts and stops?

I have a very simple app that runs on my tablet and that I start whenever I need it and stop when I am finished.

It does not write any logs but I want to track the time I use it, so I would use these hooks to write timestamps to a file.

Many thanks!

I don't know about hooks, but your app could perhaps utilize a `BEGIN{}` and `END{}` block to log such times. The former will log during compile (ie. startup), and the latter will log after the program has finished and just before exit.	[reply] [d/l] [select]

Yes, I've been thinking about that and it would probably work for my case, but in the general case (I think) a dancer app may fork several workers and that would result in serval END-blocks being fired for one run of dancer.	[reply]

You could get the PID in the script before you `dance;` and use it as a conditional in the END block. The way forward always starts with a minimal test.	[reply] [d/l]
