Returns an incremented value of default
according to arg
.
Terminates option parsing. Optional parameter arg
is a string pushed back to be the first non-option argument.
Puts option summary into to
and returns to
. Yields each line if a block is given.
to
Output destination, which must have method <<. Defaults to [].
width
Width of left side, defaults to @summary_width.
max
Maximum length allowed for left side, defaults to width
- 1.
indent
Indentation, defaults to @summary_indent.

Returns the number of elements in the match array.
m = /(.)(.)(\d+)(\d)/.match("THX1138.") m.length #=> 5 m.size #=> 5
Returns the offset of the start of the nth element of the match array in the string. n can be a string or symbol to reference a named capture.
m = /(.)(.)(\d+)(\d)/.match("THX1138.") m.begin(0) #=> 1 m.begin(2) #=> 2 m = /(?<foo>.)(.)(?<bar>.)/.match("hoge") p m.begin(:foo) #=> 0 p m.begin(:bar) #=> 2
Returns a printable version of mtch.
puts /.$/.match("foo").inspect #=> #<MatchData "o"> puts /(.)(.)(.)/.match("foo").inspect #=> #<MatchData "foo" 1:"f" 2:"o" 3:"o"> puts /(.)(.)?(.)/.match("fo").inspect #=> #<MatchData "fo" 1:"f" 2:nil 3:"o"> puts /(?<foo>.)(?<bar>.)(?<baz>.)/.match("hoge").inspect #=> #<MatchData "hog" foo:"h" bar:"o" baz:"g">
Increases left margin after newline with indent
for line breaks added in the block.
Returns true if value
is a prime number, else returns false.
value
an arbitrary integer to be checked.
generator
optional. A pseudo-prime generator.
Opens a new transaction for the data store. Code executed inside a block passed to this method may read and write data to and from the data store file.
At the end of the block, changes are committed to the data store automatically. You may exit the transaction early with a call to either PStore#commit
or PStore#abort
. See those methods for details about how changes are handled. Raising an uncaught Exception
in the block is equivalent to calling PStore#abort
.
If read_only is set to true
, you will only be allowed to read from the data store during the transaction and any attempts to change the data will raise a PStore::Error
.
Note that PStore
does not support nested transactions.
Returns true if self
is a prime number, else returns false.
Since int
is already an Integer
, this always returns true
.
As int
is already an Integer
, all these methods simply return the receiver.
Returns 1.
Create the tasks defined by this task lib.
Returns true if the set contains the given object.
Note that include?
and member?
do not test member equality using ==
as do other Enumerables.
