How to allow graceful control+c?

[IdanDavidi]

Hey guys,
Is it possible to allow graceful control+c instead of getting this message?

I came up with this solution but it exits the console:

prompt = TTY::Prompt.new(interrupt: ->() { puts "\nAborted.".yellow; exit(0) })

So I guess I should replace the exit(0) with something else?
Thanks.

Hi Idan 👋

Is it possible to allow graceful control+c instead of getting this message?

It would be helpful if you could be more specific by what you mean by 'graceful control+c'. What do you want your CLI to do when a user presses Ctrl+C? You have full control over what happens when Ctrl+C is pressed and it's up to you to decide.

For example, it is quite common for programs to stop running when Ctrl+C is pressed. Often the script returns a non-zero code, in this case, code 130. You may consider using tty-exit for this like so:

prompt  = TTY::Prompt.new(interrupt: -> { TTY::Exit.exit_with(:interrupt) })

Then applications that rely on the standard exit code can respond appropriately.

Another option, if you do not wish to exit from your script is to, for example, capture the TTY::Reader::InputInterrupt error and do whatever you wish when the input gets interrupted.

@piotrmurach sorry for not being specific enough.
By default, when a user presses Ctrl + C, an error is thrown and printed to the console:

What I wish to achieve is not to show this error in the console.
I know that I can rescue this specific error, but is it possible to achieve that using the interrupt option?

I added a rescue clause on #execute in command file

rescue TTY::Reader::InputInterrupt
  puts pastel.red('Cancelled input. Data not saved')
end
