(foo, bar), bar = qux ^^^^^^^^^^
foo, bar = baz ^^^^^^^^^^^^^^
A shareable constant.

Returns the set of targets for a MultiTargetNode

bar unless foo ^^^^^^^^^^^^^^
If the stream begins with a BOM (byte order marker), consumes the BOM and sets the external encoding accordingly; returns the result encoding if found, or nil
otherwise:
File.write('t.tmp', "\u{FEFF}abc") io = File.open('t.tmp', 'rb') io.set_encoding_by_bom # => #<Encoding:UTF-8> io.close File.write('t.tmp', 'abc') io = File.open('t.tmp', 'rb') io.set_encoding_by_bom # => nil io.close
Raises an exception if the stream is not binmode or its encoding has already been set.
Sets the encoding according to the BOM (Byte Order Mark) in the string.
Returns self
if the BOM is found, otherwise +nil.
Return all reachable objects from root.
Quietly ensure the Gem
directory dir
contains all the proper subdirectories for handling default gems. If we can’t create a directory due to a permission problem, then we will silently continue.
If mode
is given, missing directories are created with this mode.
World-writable directories will never be created.
Find
an unresolved Gem::Specification
of default gem from path
Returns a string decoded from the given URL-encoded string str
.
The given string is first encoded as Encoding::ASCII-8BIT (using String#b
), then decoded (as below), and finally force-encoded to the given encoding enc
.
The returned string:
Preserves:
Characters '*'
, '.'
, '-'
, and '_'
.
Character in ranges 'a'..'z'
, 'A'..'Z'
, and '0'..'9'
.
Example:
URI.decode_www_form_component('*.-_azAZ09') # => "*.-_azAZ09"
Converts:
Character '+'
to character ' '
.
Each “percent notation” to an ASCII character.
Example:
URI.decode_www_form_component('Here+are+some+punctuation+characters%3A+%2C%3B%3F%3A') # => "Here are some punctuation characters: ,;?:"
Related: URI.decode_uri_component
(preserves '+'
).
