Quick exit command

[st0012]

Currently, all exit/quit/kill commands require an additional confirmation step.

debug/lib/debug/session.rb

Lines 236 to 251 in 4a3046b

	when 'q', 'quit', 'exit'
	if ask 'Really quit?'
	@ui.quit arg.to_i
	@tc << :continue
	else
	return :retry
	end
	# * `kill` or `q[uit]!`
	# * Stop the debuggee process.
	when 'kill', 'quit!', 'q!'
	if ask 'Really kill?'
	exit! (arg || 1).to_i
	else
	return :retry
	end

❯ rdbg foo.rb
[1, 2] in foo.rb
=> 1| a = 1
 2| puts(a)
--> #0 foo.rb:1:in `<main>'

(rdbg) exit
Really quit? [Y/n] Y

❯ rdbg foo.rb
[1, 2] in foo.rb
=> 1| a = 1
 2| puts(a)
--> #0 foo.rb:1:in `<main>'

(rdbg) quit!
Really kill? [Y/n] Y

Without changing any existing commands, I wonder if it's ok to add the exit! command? It'll allow users to quickly exit the current session without hitting Y to confirm it.

❯ exe/rdbg foo.rb
[1, 1] in foo.rb
=> 1| puts(1)
=>#0 <main> at foo.rb:1

(rdbg) exit!

I understand the motivation.

The problem is, Ruby has exit! method which terminates process immediately without care about ensure clauses. It is confusing.

[st0012]

I see. How about changing quit! then? So the command would be

• quit, q - quit with confirmation
• quit!, q! - quit immediately
• kill - kill the process with confirmation
• kill! - kill the process immediately (not exist yet)

I see. It is one idea. No exit(!) is clear (no confusion). Could you make a patch?

Of course 👍
