module IN
contains ARPA Internet specific RRs.
This is similar to PrettyPrint::format
but the result has no breaks.
maxwidth
, newline
and genspace
are ignored.
The invocation of breakable
in the block doesn’t break a line and is treated as just an invocation of text
.
Closes the incoming port and returns its previous state. All further attempts to Ractor.receive
in the ractor, and send
to the ractor will fail with Ractor::ClosedError
.
r = Ractor.new {sleep(500)} r.close_incoming #=> false r.close_incoming #=> true r.send('test') # Ractor::ClosedError (The incoming-port is already closed)
Returns one of the following:
The maximum-valued element from self
.
A new Array of maximum-valued elements selected from self
.
When no block is given, each element in self
must respond to method <=>
with an Integer.
With no argument and no block, returns the element in self
having the maximum value per method <=>
:
[0, 1, 2].max # => 2
With an argument Integer n
and no block, returns a new Array with at most n
elements, in descending order per method <=>
:
[0, 1, 2, 3].max(3) # => [3, 2, 1] [0, 1, 2, 3].max(6) # => [3, 2, 1, 0]
When a block is given, the block must return an Integer.
With a block and no argument, calls the block self.size-1
times to compare elements; returns the element having the maximum value per the block:
['0', '00', '000'].max {|a, b| a.size <=> b.size } # => "000"
With an argument n
and a block, returns a new Array with at most n
elements, in descending order per the block:
['0', '00', '000'].max(2) {|a, b| a.size <=> b.size } # => ["000", "00"]
Returns one of the following:
The minimum-valued element from self
.
A new Array of minimum-valued elements selected from self
.
When no block is given, each element in self
must respond to method <=>
with an Integer.
With no argument and no block, returns the element in self
having the minimum value per method <=>
:
[0, 1, 2].min # => 0
With Integer argument n
and no block, returns a new Array with at most n
elements, in ascending order per method <=>
:
[0, 1, 2, 3].min(3) # => [0, 1, 2] [0, 1, 2, 3].min(6) # => [0, 1, 2, 3]
When a block is given, the block must return an Integer
.
With a block and no argument, calls the block self.size-1
times to compare elements; returns the element having the minimum value per the block:
['0', '00', '000'].min { |a, b| a.size <=> b.size } # => "0"
With an argument n
and a block, returns a new Array with at most n
elements, in ascending order per the block:
['0', '00', '000'].min(2) {|a, b| a.size <=> b.size } # => ["0", "00"]
Returns the remainder after dividing self
by other
.
Examples:
11.remainder(4) # => 3 11.remainder(-4) # => 3 -11.remainder(4) # => -3 -11.remainder(-4) # => -3 12.remainder(4) # => 0 12.remainder(-4) # => 0 -12.remainder(4) # => 0 -12.remainder(-4) # => 0 13.remainder(4.0) # => 1.0 13.remainder(Rational(4, 1)) # => (1/1)
Returns 1.
Returns the imaginary part.
Complex(7).imaginary #=> 0 Complex(9, -4).imaginary #=> -4
Returns the denominator (lcm of both denominator - real and imag).
See numerator.
Returns 1
if cmp
‘s real or imaginary part is an infinite number, otherwise returns nil
.
For example: (1+1i).infinite? #=> nil (Float::INFINITY + 1i).infinite? #=> 1
Returns zero.
Returns the remainder after dividing self
by other
.
Of the Core and Standard Library classes, only Float
and Rational
use this implementation.
Examples:
11.0.remainder(4) # => 3.0 11.0.remainder(-4) # => 3.0 -11.0.remainder(4) # => -3.0 -11.0.remainder(-4) # => -3.0 12.0.remainder(4) # => 0.0 12.0.remainder(-4) # => 0.0 -12.0.remainder(4) # => -0.0 -12.0.remainder(-4) # => -0.0 13.0.remainder(4.0) # => 1.0 13.0.remainder(Rational(4, 1)) # => 1.0 Rational(13, 1).remainder(4) # => (1/1) Rational(13, 1).remainder(-4) # => (1/1) Rational(-13, 1).remainder(4) # => (-1/1) Rational(-13, 1).remainder(-4) # => (-1/1)
Returns nil
, -1, or 1 depending on whether the value is finite, -Infinity
, or +Infinity
.
Returns the denominator (always positive).
Returns:
1, if self
is Infinity
.
-1 if self
is -Infinity
.
nil
, otherwise.
Examples:
f = 1.0/0.0 # => Infinity f.infinite? # => 1 f = -1.0/0.0 # => -Infinity f.infinite? # => -1 f = 1.0 # => 1.0 f.infinite? # => nil f = 0.0/0.0 # => NaN f.infinite? # => nil
Returns the denominator (always positive). The result is machine dependent.

.
Returns true if path
matches against pattern
. The pattern is not a regular expression; instead it follows rules similar to shell filename globbing. It may contain the following metacharacters:
*
Matches any file. Can be restricted by other values in the glob. Equivalent to /.*/x
in regexp.
*
Matches all regular files
c*
Matches all files beginning with c
*c
Matches all files ending with c
*c*
Matches all files that have c
in them (including at the beginning or end).
To match hidden files (that start with a .
) set the File::FNM_DOTMATCH flag.
**
Matches directories recursively or files expansively.
?
Matches any one character. Equivalent to /.{1}/
in regexp.
[set]
Matches any one character in set
. Behaves exactly like character sets in Regexp
, including set negation ([^a-z]
).
\
Escapes the next metacharacter.
{a,b}
Matches pattern a and pattern b if File::FNM_EXTGLOB flag is enabled. Behaves like a Regexp
union ((?:a|b)
).
flags
is a bitwise OR of the FNM_XXX
constants. The same glob pattern and flags are used by Dir::glob
.
Examples:
File.fnmatch('cat', 'cat') #=> true # match entire string File.fnmatch('cat', 'category') #=> false # only match partial string File.fnmatch('c{at,ub}s', 'cats') #=> false # { } isn't supported by default File.fnmatch('c{at,ub}s', 'cats', File::FNM_EXTGLOB) #=> true # { } is supported on FNM_EXTGLOB File.fnmatch('c?t', 'cat') #=> true # '?' match only 1 character File.fnmatch('c??t', 'cat') #=> false # ditto File.fnmatch('c*', 'cats') #=> true # '*' match 0 or more characters File.fnmatch('c*t', 'c/a/b/t') #=> true # ditto File.fnmatch('ca[a-z]', 'cat') #=> true # inclusive bracket expression File.fnmatch('ca[^t]', 'cat') #=> false # exclusive bracket expression ('^' or '!')
