* Allow `show_source` for private methods
Fix https://github.com/ruby/irb/pull/577
* Pend tests on TruffleRuby
It seems `eval(..., __LINE__ + 1)` does not work.
Other similar tests are also pended on TruffleRuby, so I think it
is acceptable.
* Use `private_method_defined?` instead of `defined?`
(https://github.com/ruby/irb/pull/576)
* Simplify each_top_level_statement, reduce instance vars
* Update lib/irb/ruby-lex.rb

1. Make `RubyLex#set_input` simply assign the input block. This matches
the behavior of `RubyLex#set_prompt`.
2. Merge `RubyLex#set_input`'s IO configuration logic with `#set_auto_indent`
into `#configure_io`.

`MagicFile` was introduced around v0.9.6, which was like 14~15 years ago.
It was needed because back then we needed to read a file's magic comment
to determine the encoding of it, and read it with that encoding.
Commit: 3ee79e89
But now we expect files to be encoded in UTF-8 and don't specify encoding
through magic comments anymore, `MagicFile` can be retired.
(https://github.com/ruby/irb/pull/571)
* Simplify Locale#load
Instead of loading file content with `MagicFile` and then evaluting it,
we can just use `Kernel.load` to load the file.
* Remove unused optional argument
* Remove unused Locale#require and #toplevel_load

It was needed because back then we needed to read a file's magic comment
to determine the encoding of it, and read it with that encoding.
Commit: 3ee79e89ad
But now both EN and JA's help-message file are UTF-8 and have removed the
encoding comment, we don't need to open them with `MagicFile` anymore.
(https://github.com/ruby/irb/pull/569)
We don't have to load another file to define the legacy encoding aliases
map because there's only one definition of it. We can define it in
locale.rb directly.
(https://github.com/ruby/irb/pull/568)
In 3ee79e89ad,
`encoding_aliases.rb` was introduced to return the correct encoding object for
`ujis` and `euc` encodings.
However, the return value of `@@legacy_encoding_alias_map[@encoding_name]`
is always overridden by a second look up with `Encoding.find(@encoding_name)`.
So the logic didn't work as expected.
This commit fixes the problem.
(https://github.com/ruby/irb/pull/564)
The current method-redefining approach brings little benefit, makes it
harder to understand the code, and causes warnings like:
> warning: method redefined; discarding old execute
This patch simplifies it while displaying more helpful message when rdoc
couldn't be loaded.
<Class/Module>`
(https://github.com/ruby/irb/pull/562)
Instead of always printing methods inherited from Class or Module, IRB by
default should filter them out unless `<Class/Module>` is specified to be
either of those.
(https://github.com/ruby/irb/pull/559)
* Remove unnecessary command argument generation code
Now that all the supported Ruby versions handle splat args and splat kwargs,
we don't need that args generation code anymore.
* Remove unused command definition code
If we look at `@EXTEND_COMMANDS`, all commands are defined in a file, which
means the `if load_file` branch is always executed. Therefore we can drop
the else branch of that condition.
* Avoid defining unnecessary command methods
There's no need to define another command method just to call `Command.execute`.
Ruby implementations like JRuby and TruffleRuby already indicate their
compatibility target with RUBY_VERSION. We don't need to exclude
them from accepting keyword arguments as long as they target 2.7+.

Consider completion for this example: `foo.bar.b`
Without type information, it is hard to know the return value of the `bar`
method, so the current implementation interates through `ObjectSpace` to
get all possible candidates for the second method.
In small projects, the performance and accuracy are acceptable. But in
bigger projects, the performance is unacceptable and the accuracy is mostly
poor.
So this commit drops the support for chained methods' completion.
`IRB::Inspector#inspect_value` errors
(https://github.com/ruby/irb/pull/511)
**Before**
```
irb(main):001:0> c = Cat.new "foo"
(Object doesn't support #inspect)
=>
```
**After**
```
irb(main):001:0> c = Cat.new "foo"
An error occurred when inspecting the object: #<NoMethodError: undefined method `is_a?' for foo:Cat
if obj.is_a?(String)
^^^^^^>
Result of Kernel#inspect: #<Cat:0x0000000109090d80 @name="foo">
=>
```
Some background for this refactor:
1. Through a RubyLex instance's lifetime, the context passed to its methods
should be the same.
Given that `Context` is only initialised in `Irb#initialize`,
this should be true.
2. When `RubyLex` is initialised, the context object should be accessible.
This is also true in all 3 of `RubyLex.new`'s invocations.
With the above observations, we should be able to store the context in `RubyLex`
as an instance variable. And doing so will make `RubyLex`'s instance methods
easier to use and maintain.

When the main object is frozen, `IRB` wraps a `SimpleDelegator` around it.
But because `SimpleDelegator` doesn't delegate private methods, methods like
`require_relative` or `const_get` would cause error, which are needed for
lazily loading commands.
This commit works around this limitation by avoiding those private method calls
when setting up command execution.
methods
(https://github.com/ruby/irb/pull/502)
* Remove unnecessary parameter defaults
These methods are always called with tokens specified. So their default
`@tokens` value is never used and is misleading.
* Remove unnecessary context default
* Require tokens for `RubyLex#check_state`
(https://github.com/ruby/irb/pull/504)
* Simplify `RubyLex#set_prompt`
It's optional argument is never used by any caller.
* Remove the optional `p` argument from `RubyLex#set_input`
The argument is only used in a test case, which can be easily replaced by
a block argument.
(https://github.com/ruby/irb/pull/489)
* Remove unnecessary Binding#source_location check
`Binding#source_location` was added in 2.6, which is the minimum supported
version now. So this check is no longer necessary.
* Remove unused IRB.delete_caller
This method was added in the earliest version of IRB:
f47808999d
But it's not currently referenced by anything. We can verify this with a
org-wide search result:
https://github.com/search?q=org%3Aruby+delete_caller&type=code
(https://github.com/ruby/irb/pull/350)
Simplify part of regex ``[_a-zA-Z0-9]`` with equivalent shorthand ``\w``.
Replace case-when with match ``$1`` or default value ``?"``, making intention more clear.
(https://github.com/ruby/irb/pull/478)
Given that `show_doc` already supports syntax like `String#gsub`, it
should be able to take it in non-string form too, like `edit` and
`show_source` do. This ensures users can have a consistent syntax on
argument between different commands.
