Results for: "Array.new"

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 URI::Parser.make_regexp.

Args

str

String to remove escapes from

escaped

Regexp to apply. Defaults to self.regexp[:ESCAPED]

Description

Removes escapes from str.

Args

uri

String

Description

Parses uri and constructs either matching URI scheme object (File, FTP, HTTP, HTTPS, LDAP, LDAPS, or MailTo) or URI::Generic.

Usage

p = URI::Parser.new
p.parse("ldap://ldap.example.com/dc=example?user=john")
#=> #<URI::LDAP ldap://ldap.example.com/dc=example?user=john>

Description

Removes escapes from str.

Returns true if this lock is currently held by current thread.

Removes all objects from the queue.

Removes all objects from the queue.

Parses the given string into an abstract syntax tree, returning the root node of that tree.

SyntaxError is raised if the given string is invalid syntax.

RubyVM::AbstractSyntaxTree.parse("x = 1 + 2")
# => #<RubyVM::AbstractSyntaxTree::Node:SCOPE@1:0-1:9>

Returns HTML-unescaped string.

Returns URL-escaped string following RFC 3986.

Returns URL-unescaped string (application/x-www-form-urlencoded).

URL-decode an application/x-www-form-urlencoded string with encoding(optional).

string = CGI.unescape("%27Stop%21%27+said+Fred")
   # => "'Stop!' said Fred"

URL-encode a string following RFC 3986 Space characters (+“ ”+) are encoded with (+“%20”+)

url_encoded_string = CGI.escape("'Stop!' said Fred")
   # => "%27Stop%21%27%20said%20Fred"

Unescape a string that has been HTML-escaped

CGI.unescapeHTML("Usage: foo "bar" <baz>")
   # => "Usage: foo \"bar\" <baz>"

Undo escaping such as that done by CGI.escapeElement()

print CGI.unescapeElement(
        CGI.escapeHTML('<BR><A HREF="url"></A>'), "A", "IMG")
  # "&lt;BR&gt;<A HREF="url"></A>"

print CGI.unescapeElement(
        CGI.escapeHTML('<BR><A HREF="url"></A>'), ["A", "IMG"])
  # "&lt;BR&gt;<A HREF="url"></A>"

See IO#readchar.

See IO#readline.

Similar to read, but raises EOFError at end of string instead of returning nil, as well as IO#sysread does.

Reads at most maxlen bytes from the stream. If buf is provided it must reference a string which will receive the data.

See IO#readpartial for full details.

Reads lines from the stream which are separated by eol.

See also gets

Reads a line from the stream which is separated by eol.

Raises EOFError if at end of file.

Reads a one-character string from the stream. Raises an EOFError at end of file.

If a block is given, it prints out each of the elements encountered. Block parameters are (in that order):

• depth: The recursion depth, plus one with each constructed value being encountered (Integer)

• offset: Current byte offset (Integer)

• header length: Combined length in bytes of the Tag and Length headers. (Integer)

• length: The overall remaining length of the entire data (Integer)

• constructed: Whether this value is constructed or not (Boolean)

• tag_class: Current tag class (Symbol)

• tag: The current tag number (Integer)

Example

der = File.binread('asn1data.der')
OpenSSL::ASN1.traverse(der) do | depth, offset, header_len, length, constructed, tag_class, tag|
  puts "Depth: #{depth} Offset: #{offset} Length: #{length}"
  puts "Header length: #{header_len} Tag: #{tag} Tag class: #{tag_class} Constructed: #{constructed}"
end
