Like ‘take_while` except when it stops iterating, it also returns the line that caused it to stop

Fetch the leading comments of the value.
Configure the leading comments field for this repository and return self.
The default encoding for Ruby files is UTF-8.
Build a diagnostic from the given prism parse error.

Verifies each certificate in chain has signed the following certificate and is valid for the given time.
Returns the element of self at offset index if index is in range; index must be an integer-convertible object.
With the single argument index and no block, returns the element at offset index:
a = [:foo, 'bar', 2] a.fetch(1) # => "bar" a.fetch(1.1) # => "bar"
If index is negative, counts from the end of the array:
a = [:foo, 'bar', 2] a.fetch(-1) # => 2 a.fetch(-2) # => "bar"
With arguments index and default_value (which may be any object) and no block, returns default_value if index is out-of-range:
a = [:foo, 'bar', 2] a.fetch(1, nil) # => "bar" a.fetch(3, :foo) # => :foo
With argument index and a block, returns the element at offset index if index is in range (and the block is not called); otherwise calls the block with index and returns its return value:
a = [:foo, 'bar', 2] a.fetch(1) {|index| raise 'Cannot happen' } # => "bar" a.fetch(50) {|index| "Value for #{index}" } # => "Value for 50"

With a block given, iterates over the elements of self, passing each element to the block; returns self:
a = [:foo, 'bar', 2] a.each {|element| puts "#{element.class} #{element}" }
Output:
Symbol foo String bar Integer 2
Allows the array to be modified during iteration:
a = [:foo, 'bar', 2] a.each {|element| puts element; a.clear if element.to_s.start_with?('b') }
Output:
foo bar
With no block given, returns a new Enumerator.

Returns the element from self found by a binary search, or nil if the search found no suitable element.

Returns a 1-character string containing the character represented by the value of self, according to the given encoding.
65.chr # => "A" 0.chr # => "\x00" 255.chr # => "\xFF" string = 255.chr(Encoding::UTF_8) string.encoding # => Encoding::UTF_8
Raises an exception if self is negative.
