Pushes character c back onto the stream such that a subsequent buffered character read will return it.
Unlike IO#getc
multiple bytes may be pushed back onto the stream.
Has no effect on unbuffered reads (such as sysread).
Writes s to the stream. If the argument is not a String
it will be converted using .to_s
method. Returns the number of bytes written.
Return true
if the PRNG has been seeded with enough data, false
otherwise.

Returns an array of Range
objects that represent the value of field 'Range'
, or nil
if there is no such field; see Range request header:
req = Net::HTTP::Get.new(uri) req['Range'] = 'bytes=0-99,200-299,400-499' req.range # => [0..99, 200..299, 400..499] req.delete('Range') req.range # # => nil
Adds a separated list. The list is separated by comma with breakable space, by default.
seplist
iterates the list
using iter_method
. It yields each object to the block given for seplist
. The procedure separator_proc
is called between each yields.
If the iteration is zero times, separator_proc
is not called at all.
If separator_proc
is nil or not given, +lambda { comma_breakable
}+ is used. If iter_method
is not given, :each is used.
For example, following 3 code fragments has similar effect.
q.seplist([1,2,3]) {|v| xxx v } q.seplist([1,2,3], lambda { q.comma_breakable }, :each) {|v| xxx v } xxx 1 q.comma_breakable xxx 2 q.comma_breakable xxx 3
Generate a random alphanumeric string.
The argument n specifies the length, in characters, of the alphanumeric string to be generated. The argument chars specifies the character list which the result is consist of.
If n is not specified or is nil, 16 is assumed. It may be larger in the future.
The result may contain A-Z, a-z and 0-9, unless chars is specified.
require 'random/formatter' Random.alphanumeric #=> "2BuBuLf3WfSKyQbR" # or prng = Random.new prng.alphanumeric(10) #=> "i6K93NdqiH" Random.alphanumeric(4, chars: [*"0".."9"]) #=> "2952" # or prng = Random.new prng.alphanumeric(10, chars: [*"!".."/"]) #=> ",.,++%/''."
Writes pemmable
, which must respond to to_pem
to path
with the given permissions
. If passed cipher
and passphrase
those arguments will be passed to to_pem
.

Set
the real group ID of the calling process to group. Not available on all platforms.
Sets the (user) real and/or effective user IDs of the current process to rid and eid, respectively. A value of -1
for either means to leave that ID unchanged. Not available on all platforms.
Sets the (group) real and/or effective group IDs of the current process to rid and eid, respectively. A value of -1
for either means to leave that ID unchanged. Not available on all platforms.
