[ruby/irb] Improve how command calls' return value is handled

2024-06-18T15:15:23+00:00

(https://github.com/ruby/irb/pull/972)

In #934, we changed command calls to return nil only. This PR improves
the behaviour even further by:

- Not echoing the `nil` returned by command calls
- Not overriding previous return value stored in `_` with the
  `nil` from commands

[ruby/irb] Revamp `help` command

2024-02-18T18:21:08+00:00

(https://github.com/ruby/irb/pull/877)

* Make help command display help for individual commands

Usage: `help [command]`

If the command is not specified, it will display a list of all available commands.

If the command is specified, it will display the banner OR description of the command.

If the command is not found, it will display a message saying that the command is not found.

* Rename test/irb/cmd to test/irb/command

* Add banner to edit and ls commands

* Promote help command in the help message

1. Make `show_cmds` an alias of `help` so it's not displayed in the help message
2. Update description of the help command to reflect `help ` syntax

* Rename banner to help_message

[ruby/irb] Support repeating debugger input by passing empty input

2024-02-16T16:12:54+00:00

to it
(https://github.com/ruby/irb/pull/856)

* Test IRB's behaviour with empty input

* Handle empty input and pass it to debugger

Since `rdbg` accepts empty input to repeat the previous command, IRB
should take empty input in `irb:rdbg` sessions and pass them to the
debugger.

Currently, IRB simply ignores empty input and does nothing. This commit
creates `EmptyInput` to represent empty input so it can fit into the
current IRB's input processing flow in `Irb#eval_input`.
