Class for reading entries out of a tar file

Like String#strip, except that any modifications are made in self; returns self if any modification are made, nil otherwise.

Related: String#lstrip!, String#strip!.

Returns a copy of self with leading whitespace removed; see Whitespace in Strings:

whitespace = "\x00\t\n\v\f\r "
s = whitespace + 'abc' + whitespace
s        # => "\u0000\t\n\v\f\r abc\u0000\t\n\v\f\r "
s.lstrip # => "abc\u0000\t\n\v\f\r "

Returns a copy of the receiver with trailing whitespace removed; see Whitespace in Strings:

whitespace = "\x00\t\n\v\f\r "
s = whitespace + 'abc' + whitespace
s        # => "\u0000\t\n\v\f\r abc\u0000\t\n\v\f\r "
s.rstrip # => "\u0000\t\n\v\f\r abc"

Returns underlying string:

StringIO.open('foo') do |strio|
  p strio.string
  strio.string = 'bar'
  p strio.string
end

Output:

"foo"
"bar"

Related: StringIO#string= (assigns the underlying string).

Assigns the underlying string as other_string, and sets position to zero; returns other_string:

StringIO.open('foo') do |strio|
  p strio.string
  strio.string = 'bar'
  p strio.string
end

Output:

"foo"
"bar"

Related: StringIO#string (returns the underlying string).

Returns the string being scanned.

Changes the string being scanned to str and resets the scanner. Returns str.

Returns the target string if it was frozen; otherwise, returns a frozen copy of the target string:

m = /(.)(.)(\d+)(\d)/.match("THX1138.")
# => #<MatchData "HX1138" 1:"H" 2:"X" 3:"113" 4:"8">
m.string # => "THX1138."

Returns a string converted from object.

Tries to convert object to a string using to_str first and to_s second:

String([0, 1, 2])        # => "[0, 1, 2]"
String(0..5)             # => "0..5"
String({foo: 0, bar: 1}) # => "{:foo=>0, :bar=>1}"

Raises TypeError if object cannot be converted to a string.

Returns a string containing the IP address representation in canonical form.

Returns a string containing the RFC-2045-compliant Base64-encoding of bin.

Per RFC 2045, the returned string may contain the URL-unsafe characters + or /; see Encoding Character Set above:

Base64.strict_encode64("\xFB\xEF\xBE") # => "++++\n"
Base64.strict_encode64("\xFF\xFF\xFF") # => "////\n"

The returned string may include padding; see Padding above.

Base64.strict_encode64('*') # => "Kg==\n"

The returned string will have no newline characters, regardless of its length; see Newlines above:

Base64.strict_encode64('*') # => "Kg=="
Base64.strict_encode64('*' * 46)
# => "KioqKioqKioqKioqKioqKioqKioqKioqKioqKioqKioqKioqKioqKioqKioqKg=="

The string to be encoded may itself contain newlines, which will be encoded as ordinary Base64:

Base64.strict_encode64("\n\n\n") # => "CgoK"
s = "This is line 1\nThis is line 2\n"
Base64.strict_encode64(s) # => "VGhpcyBpcyBsaW5lIDEKVGhpcyBpcyBsaW5lIDIK"

Returns a string containing the decoding of an RFC-2045-compliant Base64-encoded string str:

s = "VGhpcyBpcyBsaW5lIDEKVGhpcyBpcyBsaW5lIDIK"
Base64.strict_decode64(s) # => "This is line 1\nThis is line 2\n"

Non-Base64 characters in str not allowed; see Encoding Character Set above: these include newline characters and characters - and /:

Base64.strict_decode64("\n") # Raises ArgumentError
Base64.strict_decode64('-')  # Raises ArgumentError
Base64.strict_decode64('_')  # Raises ArgumentError

Padding in str, if present, must be correct:

Base64.strict_decode64("MDEyMzQ1Njc")   # Raises ArgumentError
Base64.strict_decode64("MDEyMzQ1Njc=")  # => "01234567"
Base64.strict_decode64("MDEyMzQ1Njc==") # Raises ArgumentError

Format and print out counters as a String. This returns a non-empty content only when --yjit-stats is enabled.

Returns help string of OLE method. If the help string is not found, then the method returns nil.

tobj = WIN32OLE_TYPE.new('Microsoft Internet Controls', 'IWebBrowser')
method = WIN32OLE_METHOD.new(tobj, 'Navigate')
puts method.helpstring # => Navigates to a URL or file.

Returns help string.

tobj = WIN32OLE_TYPE.new('Microsoft Internet Controls', 'IWebBrowser')
puts tobj.helpstring # => Web Browser interface

Creates a new string of the given length and yields a zero-copy IO::Buffer instance to the block which uses the string as a source. The block is expected to write to the buffer and the string will be returned.

IO::Buffer.string(4) do |buffer|
  buffer.set_string("Ruby")
end
# => "Ruby"
