As @peterzhu2118 and @duerst have pointed out, putting string method's RDoc into doc/ (which allows non-ASCII in examples) makes the "click to toggle source" feature not work for that method. This PR moves the primary method doc back into string.c, then includes RDoc from doc/string/*.rdoc, and also removes doc/string.rdoc. The affected methods are: ::new #bytes #each_byte #each_line #split The call-seq is in string.c because it works there; it did not work when the call-seq is in doc/string/*.rdoc. This PR also updates the relevant guidance in doc/documentation_guide.rdoc.

Returns a new \String that is a copy of +string+.
|
|
|
|
With no arguments, returns the empty string with the Encoding <tt>ASCII-8BIT</tt>:
|
|
s = String.new
|
|
s # => ""
|
|
s.encoding # => #<Encoding:ASCII-8BIT>
|
|
|
|
With the single \String argument +string+, returns a copy of +string+
|
|
with the same encoding as +string+:
|
|
s = String.new('Que veut dire ça?')
|
|
s # => "Que veut dire ça?"
|
|
s.encoding # => #<Encoding:UTF-8>
|
|
|
|
Literal strings like <tt>""</tt> or here-documents always use
|
|
Encoding@Script+encoding, unlike String.new.
|
|
|
|
With keyword +encoding+, returns a copy of +str+
|
|
with the specified encoding:
|
|
s = String.new(encoding: 'ASCII')
|
|
s.encoding # => #<Encoding:US-ASCII>
|
|
s = String.new('foo', encoding: 'ASCII')
|
|
s.encoding # => #<Encoding:US-ASCII>
|
|
|
|
Note that these are equivalent:
|
|
s0 = String.new('foo', encoding: 'ASCII')
|
|
s1 = 'foo'.force_encoding('ASCII')
|
|
s0.encoding == s1.encoding # => true
|
|
|
|
With keyword +capacity+, returns a copy of +str+;
|
|
the given +capacity+ may set the size of the internal buffer,
|
|
which may affect performance:
|
|
String.new(capacity: 1) # => ""
|
|
String.new(capacity: 4096) # => ""
|
|
|
|
The +string+, +encoding+, and +capacity+ arguments may all be used together:
|
|
|
|
String.new('hello', encoding: 'UTF-8', capacity: 25)
