CSV::Row#[]=

Looks up the field by the semantics described in CSV::Row.field() and assigns the value.

Assigning past the end of the row with an index will set all pairs between to [nil, nil]. Assigning to an unused header appends the new pair.

CSV::Table#[]=

In the default mixed mode, this method assigns rows for index access and columns for header access. You can force the index association by first calling by_col!() or by_row!().

Rows may be set to an Array of values (which will inherit the table’s headers()) or a CSV::Row.

Columns may be set to a single value, which is copied to each row of the column, or an Array of values. Arrays of values are assigned to rows top to bottom in row major order. Excess values are ignored and if the Array does not have a value for each row the extra rows will receive a nil.

Assigning to an existing column or row clobbers the data. Assigning to new columns creates them at the right end of the table.

DRb::GW#[]=

Stores value v at key in the GW

Racc::ISet#[]=

No documentation available

REXML::Elements#[]=

Sets an element, replacing any previous matching element. If no existing element is found ,the element is added.

index: Used to find a matching element to replace. See []().
element: The element to replace the existing element with the previous element
Returns: nil if no previous element was found.

doc = Document.new '<a/>'
doc.root.elements[10] = Element.new('b')    #-> <a><b/></a>
doc.root.elements[1]                        #-> <b/>
doc.root.elements[1] = Element.new('c')     #-> <a><c/></a>
doc.root.elements['c'] = Element.new('d')   #-> <a><d/></a>

REXML::Attributes#[]=

Sets an attribute, overwriting any existing attribute value by the same name. Namespace is significant.

name: the name of the attribute
value: (optional) If supplied, the value of the attribute. If nil, any existing matching attribute is deleted.
Returns: Owning element

doc = Document.new "<a x:foo='1' foo='3'/>"
doc.root.attributes['y:foo'] = '2'
doc.root.attributes['foo'] = '4'
doc.root.attributes['x:foo'] = nil

REXML::Parent#[]=

Set an index entry. See Array.[]= @param index the index of the element to set @param opt either the object to set, or an Integer length @param child if opt is an Integer, this is the child to set @return the parent (self)

REXML::XPathParser#[]=

No documentation available

Gem::ConfigFile#[]=

Set configuration option key to value.

WEBrick::HTTPResponse#[]=

Sets the response header field to value

YAML::DBM#[]=

Set key to value in database.

value will be converted to YAML before storage.

See store for more information.

Net::HTTPHeader#[]=

Sets the header field corresponding to the case-insensitive key.

Gem::done_installing

Adds a post-installs hook that will be passed a Gem::DependencyInstaller and a list of installed specifications when Gem::DependencyInstaller#install is complete

Module::nesting

Returns the list of Modules nested at the point of call.

module M1
  module M2
    $a = Module.nesting
  end
end
$a           #=> [M1::M2, M1]
$a[0].name   #=> "M1::M2"

GetoptLong#ordering=

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.

Proc#binding

Returns the binding associated with prc.

def fred(param)
  proc {}
end

b = fred(99)
eval("param", b.binding)   #=> 99

TracePoint#binding

Return the generated binding object from event

Kernel#binding

Returns a Binding object, describing the variable and method bindings at the point of call. This object can be used when calling eval to execute the evaluated command in this environment. See also the description of class Binding.

def get_binding(param)
  binding
end
b = get_binding("hello")
eval("param", b)   #=> "hello"
