Results for: "max_by"

Formats the errors in a human-readable way and return them as a string.

Returns true if the given node is a command node.

Verifies if the arguments match with this key event. Nil arguments are ignored, but at least one must be passed as non-nil. To verify that no control keys were pressed, pass an empty array: ‘control_keys: []`.

Does this dependency request match spec?

NOTE: match? only matches prerelease versions when dependency is a prerelease dependency.

Returns a new lazy enumerator with the concatenated results of running block once for every element in the lazy enumerator.

["foo", "bar"].lazy.flat_map {|i| i.each_char.lazy}.force
#=> ["f", "o", "o", "b", "a", "r"]

A value x returned by block is decomposed if either of the following conditions is true:

• x responds to both each and force, which means that x is a lazy enumerator.

• x is an array or responds to to_ary.

Otherwise, x is contained as-is in the return value.

[{a:1}, {b:2}].lazy.flat_map {|i| i}.force
#=> [{:a=>1}, {:b=>2}]

Like Enumerable#filter_map, but chains operation to be lazy-evaluated.

(1..).lazy.filter_map { |i| i * 2 if i.even? }.first(5)
#=> [4, 8, 12, 16, 20]

Like Enumerable#map, but chains operation to be lazy-evaluated.

(1..Float::INFINITY).lazy.map {|i| i**2 }
#=> #<Enumerator::Lazy: #<Enumerator::Lazy: 1..Infinity>:map>
(1..Float::INFINITY).lazy.map {|i| i**2 }.first(3)
#=> [1, 4, 9]

Emit a sequence with map and tag

Called when a map starts.

anchor is the anchor associated with the map or nil. tag is the tag associated with the map or nil. implicit is a boolean indicating whether or not the map was implicitly started. style is an integer indicating the mapping style.

See the constants in Psych::Nodes::Mapping for the possible values of style.

Example

Here is a YAML document that exercises most of the possible ways this method can be called:

---
k: !!map { hello: world }
v: &pewpew
  hello: world

The above YAML document consists of three maps, an outer map that contains two inner maps. Below is a matrix of the parameters sent in order to represent these three maps:

# anchor    tag                       implicit  style
[nil,       nil,                      true,     1     ]
[nil,       "tag:yaml.org,2002:map",  false,    2     ]
["pewpew",  nil,                      true,     1     ]

Called when a map ends

Start emitting a YAML map with anchor, tag, an implicit start and end, and style.

See Psych::Handler#start_mapping

Emit the end of a mapping.

See Psych::Handler#end_mapping

Returns major version.

tobj = WIN32OLE::Type.new('Microsoft Word 10.0 Object Library', 'Documents')
puts tobj.major_version # => 8

Returns the type library major version.

tlib = WIN32OLE::TypeLib.new('Microsoft Excel 9.0 Object Library')
puts tlib.major_version # -> 1

Returns the major part of File_Stat#dev or nil.

File.stat("/dev/fd1").dev_major   #=> 2
File.stat("/dev/tty").dev_major   #=> 5

Returns the major part of File_Stat#rdev or nil.

File.stat("/dev/fd1").rdev_major   #=> 2
File.stat("/dev/tty").rdev_major   #=> 5
