Results for: "strip"

Try to convert obj into a hash, using to_hash method. Returns converted hash or nil if obj cannot be converted for any reason.

Hash.try_convert({1=>2})   # => {1=>2}
Hash.try_convert("1=>2")   # => nil

Returns true if headers are written in output. See CSV::new for details.

Returns true blank lines are skipped by the parser. See CSV::new for details.

Returns true if the ipaddr is an IPv4-mapped IPv6 address.

Returns true if the ipaddr is an IPv4-compatible IPv6 address.

Returns a new ipaddr built by converting the native IPv4 address into an IPv4-mapped IPv6 address.

Returns a new ipaddr built by converting the native IPv4 address into an IPv4-compatible IPv6 address.

Returns a string for DNS reverse lookup compatible with RFC3172.

Returns a string for DNS reverse lookup compatible with RFC1886.

Returns the submatrix obtained by deleting the specified row and column.

Matrix.diagonal(9, 5, -3, 4).first_minor(1, 2)
  => 9 0 0
     0 0 0
     0 0 4

Returns the portion of the original string after the current match. Equivalent to the special variable $'.

m = /(.)(.)(\d+)(\d)/.match("THX1138: The Movie")
m.post_match   #=> ": The Movie"

Returns the factorization of value.

Parameters

value

An arbitrary integer.

generator

Optional. A pseudo-prime generator. generator.succ must return the next pseudo-prime number in the ascending order. It must generate all prime numbers, but may also generate non prime numbers too.

Exceptions

ZeroDivisionError

when value is zero.

Example

For an arbitrary integer:

n = p_1**e_1 * p_2**e_2 * .... * p_n**e_n,

prime_division(n) returns:

[[p_1, e_1], [p_2, e_2], ...., [p_n, e_n]].

Prime.prime_division(12) #=> [[2,2], [3,1]]

Raises PStore::Error if the calling code is not in a PStore#transaction.

Returns the factorization of self.

See Prime#prime_division for more details.

Iterates the given block over all prime numbers.

See Prime#each for more details.

List of options that will be supplied to RDoc

Sets the system path (the Shell instance’s PATH environment variable).

path should be an array of directory name strings.

Returns an array of the names of the thread-local variables (as Symbols).

thr = Thread.new do
  Thread.current.thread_variable_set(:cat, 'meow')
  Thread.current.thread_variable_set("dog", 'woof')
end
thr.join               #=> #<Thread:0x401b3f10 dead>
thr.thread_variables   #=> [:dog, :cat]

Note that these are not fiber local variables. Please see Thread#[] and Thread#thread_variable_get for more details.
