Launch app from Elixir then exit BEAM. (Personal task scheduler)

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.

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

I need to do some things like:

• if Slack was not open by the script today already, and if we are in Monday..Friday, then open Slack.
• If some Gitlab project API returns a non-empty list of issues, then open a tab in Firefox to a certain URL calculated from the issues list.

I know it could be done with unix commands but yeah, I would like to learn how to fork and “unlink” from the parent.
