The old code of IRB still uses this method. The warning is noisy on
rails console.
In principle, Ruby 3.1 deprecates nothing, so let's avoid the
deprecation for the while.
I think It is not so hard to continue to maintain it as it is a trivial
shim.

Alias `#inspect` as `#to_s` also in the new `Ripper::Lexer::Elem`
class, so that `puts Ripper::Lexer.new(code).scan` shows the
attributes.

|
Discussed in https://github.com/ruby/ruby/pull/5093#issuecomment-964426481.
> it would be enough to mimic only [] for almost all cases
This adds back the `Lexer::Elem#[]` and `Lexer::State#[]` and adds deprecation warnings for them.
|
|
The last element in the `@buf` may be either an array or an `Elem`. In the case it is an `Elem` we iterate over every element, when we do not need to. This check guards that case by ensuring that we only iterate over an array of elements.

## Concept
I am proposing we replace the Struct implementation of data structures inside of ripper with real classes.
This will improve performance and the implementation is not meaningfully more complicated.
## Example
Struct versus class comparison:
```ruby
Elem = Struct.new(:pos, :event, :tok, :state, :message) do
def initialize(pos, event, tok, state, message = nil)
super(pos, event, tok, State.new(state), message)
end
# ...
def to_a
a = super
a.pop unless a.empty?
a
end
end
class ElemClass
attr_accessor :pos, :event, :tok, :state, :message
def initialize(pos, event, tok, state, message = nil)
@pos = pos
@event = event
@tok = tok
@state = State.new(state)
@message = message
end
def to_a
if @message
[@pos, @event, @tok, @state, @message]
else
[@pos, @event, @tok, @state]
end
end
end
# stub state class creation for now
class State; def initialize(val); end; end
```
## MicroBenchmark creation
```ruby
require 'benchmark/ips'
require 'ripper'
pos = [1, 2]
event = :on_nl
tok = "\n".freeze
state = Ripper::EXPR_BEG
Benchmark.ips do |x|
x.report("struct") { Elem.new(pos, event, tok, state) }
x.report("class ") { ElemClass.new(pos, event, tok, state) }
x.compare!
end; nil
```
Gives ~1.2x faster creation:
```
Warming up --------------------------------------
struct 263.983k i/100ms
class 303.367k i/100ms
Calculating -------------------------------------
struct 2.638M (± 5.9%) i/s - 13.199M in 5.023460s
class 3.171M (± 4.6%) i/s - 16.078M in 5.082369s
Comparison:
class : 3170690.2 i/s
struct: 2638493.5 i/s - 1.20x (± 0.00) slower
```
## MicroBenchmark `to_a` (Called by Ripper.lex for every element)
```ruby
require 'benchmark/ips'
require 'ripper'
pos = [1, 2]
event = :on_nl
tok = "\n".freeze
state = Ripper::EXPR_BEG
struct = Elem.new(pos, event, tok, state)
from_class = ElemClass.new(pos, event, tok, state)
Benchmark.ips do |x|
x.report("struct") { struct.to_a }
x.report("class ") { from_class.to_a }
x.compare!
end; nil
```
Gives 1.46x faster `to_a`:
```
Warming up --------------------------------------
struct 612.094k i/100ms
class 893.233k i/100ms
Calculating -------------------------------------
struct 6.121M (± 5.4%) i/s - 30.605M in 5.015851s
class 8.931M (± 7.9%) i/s - 44.662M in 5.039733s
Comparison:
class : 8930619.0 i/s
struct: 6121358.9 i/s - 1.46x (± 0.00) slower
```
## MicroBenchmark data access
```ruby
require 'benchmark/ips'
require 'ripper'
pos = [1, 2]
event = :on_nl
tok = "\n".freeze
state = Ripper::EXPR_BEG
struct = Elem.new(pos, event, tok, state)
from_class = ElemClass.new(pos, event, tok, state)
Benchmark.ips do |x|
x.report("struct") { struct.pos[1] }
x.report("class ") { from_class.pos[1] }
x.compare!
end; nil
```
Gives ~1.17x faster data access:
```
Warming up --------------------------------------
struct 1.694M i/100ms
class 1.868M i/100ms
Calculating -------------------------------------
struct 16.149M (± 6.8%) i/s - 81.318M in 5.060633s
class 18.886M (± 2.9%) i/s - 95.262M in 5.048359s
Comparison:
class : 18885669.6 i/s
struct: 16149255.8 i/s - 1.17x (± 0.00) slower
```
## Full benchmark integration of this inside of Ripper.lex
Inside of this repo with this commit
```
$ cd ext/ripper
$ make
$ cat test.rb
file = File.join(__dir__, "../../array.rb")
source = File.read(file)
bench = Benchmark.measure do
10_000.times.each do
Ripper.lex(source)
end
end
puts bench
```
Then execute with and without this change 50 times:
```
rm new.txt
rm old.txt
for i in {0..50}
do
`ruby -Ilib -rripper -rbenchmark ./test.rb >> new.txt`
`ruby -rripper -rbenchmark ./test.rb >> old.txt`
done
```
I used derailed benchmarks internals to compare the results:
```
dir = Pathname(".")
branch_info = {}
branch_info["old"] = { desc: "Struct lex", time: Time.now, file: dir.join("old.txt"), name: "old" }
branch_info["new"] = { desc: "Class lex", time: Time.now, file: dir.join("new.txt"), name: "new" }
stats = DerailedBenchmarks::StatsFromDir.new(branch_info)
stats.call.banner
```
Which gave us:
```

To sum this up, the "new" version of this code (using real classes instead of structs) is 10% faster across 50 runs with a statistical significance confidence level of 99%. Histograms are for visual checksum.

To make some kind of Ractor related extensions, some functions
should be exposed.
* include/ruby/thread_native.h
* rb_native_mutex_*
* rb_native_cond_*
* include/ruby/ractor.h
* RB_OBJ_SHAREABLE_P(obj)
* rb_ractor_shareable_p(obj)
* rb_ractor_std*()
* rb_cRactor
and rm ractor_pub.h
and rename srcdir/ractor.h to srcdir/ractor_core.h
(to avoid conflict with include/ruby/ractor.h)

This commit introduces Ractor mechanism to run Ruby program in
parallel. See doc/ractor.md for more details about Ractor.
See ticket [Feature #17100] to see the implementation details
and discussions.
[Feature #17100]
This commit does not complete the implementation. You can find
many bugs on using Ractor. Also the specification will be changed
so that this feature is experimental. You will see a warning when
you make the first Ractor with `Ractor.new`.
I hope this feature can help programmers from thread-safety issues.

I noticed that some files in rubygems were executable, and I could think
of no reason why they should be.
In general, I think ruby files should never have the executable bit set
unless they include a shebang, so I run the following command over the
whole repo:
```bash
find . -name '*.rb' -type f -executable -exec bash -c 'grep -L "^#!" $1 || chmod -x $1' _ {} \;
```
