not defined
(https://github.com/ruby/irb/pull/853)
The issue (https://github.com/ruby/debug/issues/1064) is caused by a
combination of factors:
1. When user starts an IRB session without a history file, the
`@loaded_history_lines` ivar is not defined.
2. If the user then starts the `irb:rdbg` session, the history counter
is not set, because the `@loaded_history_lines` is not defined.
3. Because `irb:rdbg` saves the history before passing Ruby expression
to the debugger, it saves the history with duplicated lines. The number
grows in exponential order.
4. When the user exits the `irb:rdbg` session, the history file could be
bloated with duplicated lines.
This commit fixes the issue by resetting the history counter even when
`@loaded_history_lines` is not defined.

* Remove unnecessary code from the exit command's implementation
1. The parameters of `IRB.irb_exit` were never used. But there are some
libraries seem to call it with arguments + it's declared on the top-level
IRB constant. So I changed the params to anonymous splat instead of removing them.
2. `Context#exit` was completely unnecessary as `IRB.irb_exit` doesn't use
the `@irb` instance it passes. And since it's (or should be treated as)
a private method, I simply removed it.
3. The `exit` command doesn't use the status argument it receives at all.
But to avoid raising errors on usages like `exit 1`, I changed the argument to
anonymous splat instead removing it.
* Make exit an actual command
* Update readme

The candidate list for empty input is all methods + all variables +
all constants + all keywords. It's a long list that is not useful.

* Fix display_document params in noautocomplete mode
* Fix wrong preposing and target order in display_document
The fixed wrong-ordered value is not used in RegexpCompletor, so this change does not affect the test.

1. Because `IRB.rc_file` always generates an rc file name, even if the
file doesn't exist, we should check the file exists before trying to
load it.
2. If any type of errors occur while loading the rc file, we should
warn the user about it.

For apps/libs that test against IRB, it's recommended to set `TERM=dumb`
so they get minimum disruption from Reline's interactive-focus features.
Therefore, we should follow the convention to disable pager when `TERM=dumb`.

* Page evaluation result's output
This will make it easier to work with long output that exceeds the terminal's height.
* Use consistent TERM in rendering tests
This makes sure we get consistent result on all platforms.

* Remove trailing spaces
* Migrate show_source tests to integration tests
Because show_source tests often need to define class and/or methods,
they can easily leak state to other tests. Changing them to integration
tests will ensure that they are run in a clean environment.
* Fix NoMethodError caused by SourceFinder#method_target

If `output_modifier_proc`'s `complete` arg is true, it means the input is
submitted. In that case, debugger hint doesn't provide value to users
and adds noise to the output. So we hide it in such case.

Similar to Pry, it displays user-defined aliases in the help message with
a dedicated section. With the current default aliases, it looks like:
```
...other sections...
Aliases
$ Alias for `show_source`
@ Alias for `whereami`
```

With either `IRB.conf[:USE_PAGER] = false` or `--no-pager` commnad line flag.
I decided use `--no-pager` instead of `--use-pager` because it matches with
Pry and git's command line flags.

When user enters irb:rdbg session, they don't get the same hint that the
`debug` gem provides, like
```
(rdbg) n # next command
```
This means that users may accidentally execute commands when they want to
retrieve the value of a variable.
So this commit adds a Reline output modifier to add a simiar hint:
```
irb:rdbg(main):002> n # debug command
```
It is not exactly the same as `debug`'s because in this case the importance
is to help users distinguish between value evaluation and debugger command
execution.

I propose introducing the capability to set the IRB completion kinds via an environment variable, specifically `IRB_COMPLETOR=type`.
This feature aims to enhance the Rails console experience by allowing Rails users to specify their preferred completion more conveniently.
Currently, when using the Rails console, there's no straightforward way to globally set the type completion across a Rails application repository.
It's possible to configure this setting by placing a `.irbrc` file at the project root. However, using a .irbrc file is not ideal as it allows for broad configurations and can potentially affect the production environment.
My suggestion focuses on allowing users to set the completion to 'type' in a minimal.
This enhancement would be particularly beneficial for teams writing RBS in their Rails applications.
This type completer, integrated with RBS, would enhance completion accuracy, improving the Rails console experience.
