By overriding Object#methods, WIN32OLE might work well with did_you_mean gem. This is experimental.

require 'win32ole'
dict = WIN32OLE.new('Scripting.Dictionary')
dict.Ade('a', 1)
#=> Did you mean?  Add

Returns current codepage.

WIN32OLE.codepage # => WIN32OLE::CP_ACP

Sets current codepage. The WIN32OLE.codepage is initialized according to Encoding.default_internal. If Encoding.default_internal is nil then WIN32OLE.codepage is initialized according to Encoding.default_external.

WIN32OLE.codepage = WIN32OLE::CP_UTF8
WIN32OLE.codepage = 65001

Returns current locale id (lcid). The default locale is WIN32OLE::LOCALE_SYSTEM_DEFAULT.

lcid = WIN32OLE.locale

Sets current locale id (lcid).

WIN32OLE.locale = 1033 # set locale English(U.S)
obj = WIN32OLE_VARIANT.new("$100,000", WIN32OLE::VARIANT::VT_CY)

Returns the default value for the given key. The returned value will be determined either by the default proc or by the default value. See Default Values.

With no argument, returns the current default value:

h = {}
h.default # => nil

If key is given, returns the default value for key, regardless of whether that key exists:

h = Hash.new { |hash, key| hash[key] = "No key #{key}"}
h[:foo] = "Hello"
h.default(:foo) # => "No key foo"

Sets the default value to value; returns value:

h = {}
h.default # => nil
h.default = false # => false
h.default # => false

See Default Values.

Returns the count of entries in self:

{foo: 0, bar: 1, baz: 2}.length # => 3

Deletes the entry for the given key and returns its associated value.

If no block is given and key is found, deletes the entry and returns the associated value:

h = {foo: 0, bar: 1, baz: 2}
h.delete(:bar) # => 1
h # => {:foo=>0, :baz=>2}

If no block given and key is not found, returns nil.

If a block is given and key is found, ignores the block, deletes the entry, and returns the associated value:

h = {foo: 0, bar: 1, baz: 2}
h.delete(:baz) { |key| raise 'Will never happen'} # => 2
h # => {:foo=>0, :bar=>1}

If a block is given and key is not found, calls the block and returns the block’s return value:

h = {foo: 0, bar: 1, baz: 2}
h.delete(:nosuch) { |key| "Key #{key} not found" } # => "Key nosuch not found"
h # => {:foo=>0, :bar=>1, :baz=>2}

Removes all hash entries; returns self.

Deletes the environment variable with name if it exists and returns its value:

ENV['foo'] = '0'
ENV.delete('foo') # => '0'

If a block is not given and the named environment variable does not exist, returns nil.

If a block given and the environment variable does not exist, yields name to the block and returns the value of the block:

ENV.delete('foo') { |name| name * 2 } # => "foofoo"

If a block given and the environment variable exists, deletes the environment variable and returns its value (ignoring the block):

ENV['foo'] = '0'
ENV.delete('foo') { |name| raise 'ignored' } # => "0"

Raises an exception if name is invalid. See Invalid Names and Values.

Removes every environment variable; returns ENV:

ENV.replace('foo' => '0', 'bar' => '1')
ENV.size # => 2
ENV.clear # => ENV
ENV.size # => 0

Returns the count of environment variables:

ENV.replace('foo' => '0', 'bar' => '1')
ENV.length # => 2
ENV.size # => 2

Raises TypeError, because ENV is a singleton object. Use to_h to get a copy of ENV data as a hash.

Returns an integer representing the numeric file descriptor for the current file. Raises an ArgumentError if there isn’t a current file.

ARGF.fileno    #=> 3

Returns the current filename. “-” is returned when the current file is STDIN.

For example:

$ echo "foo" > foo
$ echo "bar" > bar
$ echo "glark" > glark

$ ruby argf.rb foo bar glark

ARGF.filename  #=> "foo"
ARGF.read(5)   #=> "foo\nb"
ARGF.filename  #=> "bar"
ARGF.skip
ARGF.filename  #=> "glark"

Returns the current file as an IO or File object. $stdin is returned when the current file is STDIN.

For example:

$ echo "foo" > foo
$ echo "bar" > bar

$ ruby argf.rb foo bar

ARGF.file      #=> #<File:foo>
ARGF.read(5)   #=> "foo\nb"
ARGF.file      #=> #<File:bar>

Calls CSV.read with source, options, and certain default options:

• headers: true

• converters: :numeric

• header_converters: :symbol

Returns a CSV::Table object.

Example:

string = "Name,Value\nfoo,0\nbar,1\nbaz,2\n"
path = 't.csv'
File.write(path, string)
CSV.table(path) # => #<CSV::Table mode:col_or_row row_count:4>

Returns the methods available to this delegate object as the union of this object’s and _getobj_ methods.

Executes the generated ERB code to produce a completed template, returning the results of that code. (See ERB::new for details on how this process can be affected by safe_level.)

b accepts a Binding object which is used to set the context of code evaluation.

Logging severity threshold (e.g. Logger::INFO).

Sets the log level; returns severity. See Log Level.

Argument severity may be an integer, a string, or a symbol:

logger.level = Logger::ERROR # => 3
logger.level = 3             # => 3
logger.level = 'error'       # => "error"
logger.level = :error        # => :error

Logger#sev_threshold= is an alias for Logger#level=.

Release code

Removes the last List.

Returns size of the match array:

m = /(.)(.)(\d+)(\d)/.match("THX1138.")
# => #<MatchData "HX1138" 1:"H" 2:"X" 3:"113" 4:"8">
m.size # => 5
