Launch app from Elixir then exit BEAM. (Personal task scheduler)
Hi,
I need to launch certain apps on work days, I need to run some checks via HTTP APIs and then maybe launch some other apps, etc.
I am not very good with bash, and some complex scenarios will be much simpler to handle with Elixir (call HTTP, parse response, parse a config file, etc).
But is it possible to start an app from an Elixir script (think Slack, Thunderbird, …) and then shutdown the BEAM while the app is still running?

I vote for the normal release and eval/rpc afterward mix release — Mix v1.20.2

It could be, but why not wrap the two together instead?
#!/bin/sh
elixir -S "script.exs" && exec open "http://example.com"
Now all you need to ensure, is that script.exs will exit with non-0 code on error.
However with a little of *NIX magic you could fork the process into the background and leave it running when the parent dies, however I think, than in your case, there are some tools that would handle all of that for you, if you would be so keen to extend about what you need exactly.
