Synopsis¶ ↑
Bundler::URI::Parser.new([opts])
Args¶ ↑
The constructor accepts a hash as options for parser. Keys of options are pattern names of Bundler::URI
components and values of options are pattern strings. The constructor generates set of regexps for parsing URIs.
You can use the following keys:
* :ESCAPED (Bundler::URI::PATTERN::ESCAPED in default) * :UNRESERVED (Bundler::URI::PATTERN::UNRESERVED in default) * :DOMLABEL (Bundler::URI::PATTERN::DOMLABEL in default) * :TOPLABEL (Bundler::URI::PATTERN::TOPLABEL in default) * :HOSTNAME (Bundler::URI::PATTERN::HOSTNAME in default)
Examples¶ ↑
p = Bundler::URI::Parser.new(:ESCAPED => "(?:%[a-fA-F0-9]{2}|%u[a-fA-F0-9]{4})") u = p.parse("http://example.jp/%uABCD") #=> #<Bundler::URI::HTTP http://example.jp/%uABCD> Bundler::URI.parse(u.to_s) #=> raises Bundler::URI::InvalidURIError s = "http://example.com/ABCD" u1 = p.parse(s) #=> #<Bundler::URI::HTTP http://example.com/ABCD> u2 = Bundler::URI.parse(s) #=> #<Bundler::URI::HTTP http://example.com/ABCD> u1 == u2 #=> true u1.eql?(u2) #=> false

Public Instance Methods
Args¶ ↑
str
-
String to make safe
unsafe
-
Regexp to apply. Defaults to
self.regexp[:UNSAFE]
Description¶ ↑
Constructs a safe String from str
, removing unsafe characters, replacing them with codes.
# File bundler/vendor/uri/lib/uri/rfc2396_parser.rb, line 287 def escape(str, unsafe = @regexp[:UNSAFE]) unless unsafe.kind_of?(Regexp) # perhaps unsafe is String object unsafe = Regexp.new("[#{Regexp.quote(unsafe)}]", false) end str.gsub(unsafe) do us = $& tmp = '' us.each_byte do |uc| tmp << sprintf('%%%02X', uc) end tmp end.force_encoding(Encoding::US_ASCII) end
Args¶ ↑
str
-
String to search
schemes
-
Patterns to apply to
str
Description¶ ↑
Attempts to parse and merge a set of URIs. If no block
given, then returns the result, else it calls block
for each element in result.
See also Bundler::URI::Parser.make_regexp
.
# File bundler/vendor/uri/lib/uri/rfc2396_parser.rb, line 249 def extract(str, schemes = nil) if block_given? str.scan(make_regexp(schemes)) { yield $& } nil else result = [] str.scan(make_regexp(schemes)) { result.push $& } result end end
# File bundler/vendor/uri/lib/uri/rfc2396_parser.rb, line 326 def inspect @@to_s.bind_call(self) end
Returns Regexp that is default self.regexp[:ABS_URI_REF]
, unless schemes
is provided. Then it is a Regexp.union with self.pattern[:X_ABS_URI]
.
# File bundler/vendor/uri/lib/uri/rfc2396_parser.rb, line 262 def make_regexp(schemes = nil) unless schemes @regexp[:ABS_URI_REF] else /(?=#{Regexp.union(*schemes)}:)#{@pattern[:X_ABS_URI]}/x end end
Args¶ ↑
uri
-
String
Description¶ ↑
Parses uri
and constructs either matching Bundler::URI
scheme object (File
, FTP
, HTTP
, HTTPS
, LDAP
, LDAPS
, or MailTo
) or Bundler::URI::Generic
.
Usage¶ ↑
p = Bundler::URI::Parser.new p.parse("ldap://ldap.example.com/dc=example?user=john") #=> #<Bundler::URI::LDAP ldap://ldap.example.com/dc=example?user=john>
# File bundler/vendor/uri/lib/uri/rfc2396_parser.rb, line 209 def parse(uri) Bundler::URI.for(*self.split(uri), self) end
Returns a split Bundler::URI
against regexp[:ABS_URI]
.

Args¶ ↑
str
-
String to remove escapes from
escaped
-
Regexp to apply. Defaults to
self.regexp[:ESCAPED]
Description¶ ↑
Removes escapes from str
.
# File bundler/vendor/uri/lib/uri/rfc2396_parser.rb, line 318 def unescape(str, escaped = @regexp[:ESCAPED]) enc = str.encoding enc = Encoding::UTF_8 if enc == Encoding::US_ASCII str.gsub(escaped) { [$&[1, 2]].pack('H2').force_encoding(enc) } end
