Results for: "uri"

Opens the file, optionally seeks to the given offset, writes string, then returns the length written. write ensures the file is closed before returning. If offset is not given in write mode, the file is truncated. Otherwise, it is not truncated.

If the last argument is a hash, it specifies option for internal open(). The key would be the following. open_args: is exclusive to others.

encoding: string or encoding

 specifies encoding of the read string.  encoding will be ignored
 if length is specified.

mode: string

 specifies mode argument for open().  it should start with "w" or "a" or "r+"
 otherwise it would cause error.

perm: fixnum

 specifies perm argument for open().

open_args: array

 specifies arguments for open() as an array.

  IO.write("testfile", "0123456789", 20) # => 10
  # File could contain:  "This is line one\nThi0123456789two\nThis is line three\nAnd so on...\n"
  IO.write("testfile", "0123456789")      #=> 10
  # File would now read: "0123456789"

Same as IO.write except opening the file in binary mode and ASCII-8BIT encoding (“wb:ASCII-8BIT”).

Writes the given object(s) to ios. Returns nil.

The stream must be opened for writing. Each given object that isn’t a string will be converted by calling its to_s method. When called without arguments, prints the contents of $_.

If the output field separator ($,) is not nil, it is inserted between objects. If the output record separator ($\) is not nil, it is appended to the output.

$stdout.print("This is ", 100, " percent.\n")

produces:

This is 100 percent.

Formats and writes to ios, converting parameters under control of the format string. See Kernel#sprintf for details.

Writes the given string to ios using a low-level write. Returns the number of bytes written. Do not mix with other methods that write to ios or you may get unpredictable results. Raises SystemCallError on error.

f = File.new("out", "w")
f.syswrite("ABCDEF")   #=> 6

Writes the given string to ios. The stream must be opened for writing. If the argument is not a string, it will be converted to a string using to_s. Returns the number of bytes written.

count = $stdout.write("This is a test\n")
puts "That was #{count} bytes of data"

produces:

This is a test
That was 15 bytes of data

Returns the original string of the pattern.

/ab+c/ix.source #=> "ab+c"

Note that escape sequences are retained as is.

/\x20\+/.source  #=> "\\x20\\+"

Callback invoked whenever a subclass of the current class is created.

Example:

class Foo
  def self.inherited(subclass)
    puts "New subclass: #{subclass}"
  end
end

class Bar < Foo
end

class Baz < Bar
end

produces:

New subclass: Bar
New subclass: Baz

Writes contents to the file.

See IO.write.

Writes contents to the file, opening it in binary mode.

See IO.binwrite.

See FileTest.writable?.

Return the entries (files and subdirectories) in the directory, each as a Pathname object.

The results contains just the names in the directory, without any trailing slashes or recursive look-up.

pp Pathname.new('/usr/local').entries
#=> [#<Pathname:share>,
#    #<Pathname:lib>,
#    #<Pathname:..>,
#    #<Pathname:include>,
#    #<Pathname:etc>,
#    #<Pathname:bin>,
#    #<Pathname:man>,
#    #<Pathname:games>,
#    #<Pathname:.>,
#    #<Pathname:sbin>,
#    #<Pathname:src>]

The result may contain the current directory #<Pathname:.> and the parent directory #<Pathname:..>.

If you don’t want . and .. and want directories, consider Pathname#children.

Obtains address information for nodename:servname.

family should be an address family such as: :INET, :INET6, etc.

socktype should be a socket type such as: :STREAM, :DGRAM, :RAW, etc.

protocol should be a protocol defined in the family, and defaults to 0 for the family.

flags should be bitwise OR of Socket::AI_* constants.

Socket.getaddrinfo("www.ruby-lang.org", "http", nil, :STREAM)
#=> [["AF_INET", 80, "carbon.ruby-lang.org", "221.186.184.68", 2, 1, 6]] # PF_INET/SOCK_STREAM/IPPROTO_TCP

Socket.getaddrinfo("localhost", nil)
#=> [["AF_INET", 0, "localhost", "127.0.0.1", 2, 1, 6],  # PF_INET/SOCK_STREAM/IPPROTO_TCP
#    ["AF_INET", 0, "localhost", "127.0.0.1", 2, 2, 17], # PF_INET/SOCK_DGRAM/IPPROTO_UDP
#    ["AF_INET", 0, "localhost", "127.0.0.1", 2, 3, 0]]  # PF_INET/SOCK_RAW/IPPROTO_IP

reverse_lookup directs the form of the third element, and has to be one of below. If reverse_lookup is omitted, the default value is nil.

+true+, +:hostname+:  hostname is obtained from numeric address using reverse lookup, which may take a time.
+false+, +:numeric+:  hostname is same as numeric address.
+nil+:              obey to the current +do_not_reverse_lookup+ flag.

If Addrinfo object is preferred, use Addrinfo.getaddrinfo.

returns a list of addrinfo objects as an array.

This method converts nodename (hostname) and service (port) to addrinfo. Since the conversion is not unique, the result is a list of addrinfo objects.

nodename or service can be nil if no conversion intended.

family, socktype and protocol are hint for preferred protocol. If the result will be used for a socket with SOCK_STREAM, SOCK_STREAM should be specified as socktype. If so, Addrinfo.getaddrinfo returns addrinfo list appropriate for SOCK_STREAM. If they are omitted or nil is given, the result is not restricted.

Similarly, PF_INET6 as family restricts for IPv6.

flags should be bitwise OR of Socket::AI_??? constants such as follows. Note that the exact list of the constants depends on OS.

AI_PASSIVE      Get address to use with bind()
AI_CANONNAME    Fill in the canonical name
AI_NUMERICHOST  Prevent host name resolution
AI_NUMERICSERV  Prevent service name resolution
AI_V4MAPPED     Accept IPv4-mapped IPv6 addresses
AI_ALL          Allow all addresses
AI_ADDRCONFIG   Accept only if any address is assigned

Note that socktype should be specified whenever application knows the usage of the address. Some platform causes an error when socktype is omitted and servname is specified as an integer because some port numbers, 512 for example, are ambiguous without socktype.

Addrinfo.getaddrinfo("www.kame.net", 80, nil, :STREAM)
#=> [#<Addrinfo: 203.178.141.194:80 TCP (www.kame.net)>,
#    #<Addrinfo: [2001:200:dff:fff1:216:3eff:feb1:44d7]:80 TCP (www.kame.net)>]

Returns underlying String object, the subject of IO.

Changes underlying String object, the subject of IO.

Appends the given string to the underlying buffer string of strio. The stream must be opened for writing. If the argument is not a string, it will be converted to a string using to_s. Returns the number of bytes written. See IO#write.

Returns the string being scanned.

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

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

Returns array of WIN32OLE_VARIABLE objects which represent variables defined in OLE class.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'XlSheetType')
vars = tobj.variables
vars.each do |v|
  puts "#{v.name} = #{v.value}"
end

The result of above sample script is follows:
  xlChart = -4109
  xlDialogSheet = -4116
  xlExcel4IntlMacroSheet = 4
  xlExcel4MacroSheet = 3
  xlWorksheet = -4167

Print an argument or list of arguments to the default output stream

cgi = CGI.new
cgi.print    # default:  cgi.print == $DEFAULT_OUTPUT.print

Set the handling of the ordering of options and arguments. A RuntimeError is raised if option processing has already started.

The supplied value must be a member of GetoptLong::ORDERINGS. It alters the processing of options as follows:

REQUIRE_ORDER :

Options are required to occur before non-options.

Processing of options ends as soon as a word is encountered that has not been preceded by an appropriate option flag.

For example, if -a and -b are options which do not take arguments, parsing command line arguments of ‘-a one -b two’ would result in ‘one’, ‘-b’, ‘two’ being left in ARGV, and only (‘-a’, ”) being processed as an option/arg pair.

This is the default ordering, if the environment variable POSIXLY_CORRECT is set. (This is for compatibility with GNU getopt_long.)

PERMUTE :

Options can occur anywhere in the command line parsed. This is the default behavior.

Every sequence of words which can be interpreted as an option (with or without argument) is treated as an option; non-option words are skipped.

For example, if -a does not require an argument and -b optionally takes an argument, parsing ‘-a one -b two three’ would result in (‘-a’,”) and (‘-b’, ‘two’) being processed as option/arg pairs, and ‘one’,‘three’ being left in ARGV.

If the ordering is set to PERMUTE but the environment variable POSIXLY_CORRECT is set, REQUIRE_ORDER is used instead. This is for compatibility with GNU getopt_long.

RETURN_IN_ORDER :

All words on the command line are processed as options. Words not preceded by a short or long option flag are passed as arguments with an option of ” (empty string).

For example, if -a requires an argument but -b does not, a command line of ‘-a one -b two three’ would result in option/arg pairs of (‘-a’, ‘one’) (‘-b’, ”), (”, ‘two’), (”, ‘three’) being processed.

Returns true if this is a symmetric matrix. Raises an error if matrix is not square.
