* Transform ls's --grep/-G option to keyword args
* Make --grep less flexible
* Support -g instead of --grep
* Suppress warnings from symbol aliases
* Use local_variables for colorize, code_block_open check, nesting_level and assignment_expression check
* Check if expression is an assignment BEFORE evaluating it. evaluate might define new localvars and change result of assignment_expression?

* pend local variable dependent test on truffleruby
code_block_open is not working on truffleruby
* Always pass context to RubyLex#lex
* Rename local_variable_assign_code generator method name
* Add assignment expression truncate test
* Add Context#local_variables and make generate_local_variables_assign_code more simple
* Update lib/irb/input-method.rb

* Use colorable: argument as the only coloring control
* Centalize color controling logic at Color.colorable?
There are 2 requirements for coloring output:
1. It's supported on the platform
2. The user wants it: `IRB.conf[:USE_COLORIZE] == true`
Right now we check 1 and 2 separately whenever we colorize things.
But it's error-prone because while 1 is the default of `colorable`
parameter, 2 always need to manually checked. When 2 is overlooked, it
causes issues like https://github.com/ruby/irb/pull/362
And there's 0 case where we may want to colorize even when the user
disables it. So I think we should merge 2 into `Color.colorable?` so it
can be automatically picked up.
* Add tests for all inspect modes
* Simplify inspectors' coloring logic
* Replace use_colorize? with Color.colorable?
* Remove Context#use_colorize cause it's redundant

This fixes at least an issue where irb will incorrectly assume
code opens a heredoc when it does not, such as this code:
```ruby
s1 = 'testing'
s2 = 'this'
s2 <<s1
p s1
s1
```
Ruby parses the `s2 <<s1` as `s2.<<(s1)`, not as a heredoc, because
`s2` is a local variable in scope. irb was using ripper without
letting ripper know that `s2` was a local variable, so ripper would
lex it as a heredoc instead of a method call.
Fix the situation by prepending a line at line 0 with all local
variable definitions in scope whenever lexing. This fixes the
heredoc issue, and potentially other issues that depend on whether
an identifier is a local variable or not.

converter not found (UTF-8 to UTF-8) (Encoding::ConverterNotFoundError)
```
First, this patch skips `Encoding::Converter.new` for the same encoding.
170531df19/lib/irb.rb (L601)
Next, this is a talk about the condition for skipping. `IRB.conf[:LC_MESSAGES].encoding`
becomes `"UTF-8"` string when `Reline.encoding_system_needs.name` is set in the below.
170531df19/lib/irb/input-method.rb (L269)
OTOH, `message.encoding` is `Encoding::UTF_8`, so these are compared as a string by this patch.

You can use "measure" command to check performance in IRB like below:
irb(main):001:0> 3
=> 3
irb(main):002:0> measure
TIME is added.
=> nil
irb(main):003:0> 3
processing time: 0.000058s
=> 3
irb(main):004:0> measure :off
=> nil
irb(main):005:0> 3
=> 3
You can set "measure :on" by "IRB.conf[:MEASURE] = true" in .irbrc, and, also,
set custom performance check method:
IRB.conf[:MEASURE_PROC][:CUSTOM] = proc { |context, code, line_no, &block|
time = Time.now
result = block.()
now = Time.now
puts 'custom processing time: %fs' % (Time.now - time) if IRB.conf[:MEASURE]
result
}
https://github.com/ruby/irb/commit/3899eaf2e2
Omit the results evaluated at assignment if they are too long.
The behavior of ECHO_ON_ASSIGNMENT being on by default is hard to understand,
so I change it to off by default. Instead, we turn OMIT_ON_ASSIGNMENT on by
default. The result is displayed on assignment, but it will always be short
and within one line of the screen.
