Sends a MOVE request to the server; returns an instance of a subclass of Net::HTTPResponse.
The request is based on the Net::HTTP::Move object created from string path and initial headers hash initheader.
http = Net::HTTP.new(hostname) http.move('/todos/1')

What does this dependency require?
Lists the external (to RubyGems) requirements that must be met for this gem to work. It’s simply information for the user.
Usage:
spec.requirements << 'libmagick, v6.0' spec.requirements << 'A good graphics card'
Set requirements to req, ensuring it is an array.
Is remote fetching enabled?
Returns an File instance opened console.
If sym is given, it will be sent to the opened console with args and the result will be returned instead of the console IO itself.
You must require ‘io/console’ to use this method.
Returns system configuration variable using confstr().
name should be a constant under Etc which begins with CS_.
The return value is a string or nil. nil means no configuration-defined value. (confstr() returns 0 but errno is not set.)
Etc.confstr(Etc::CS_PATH) #=> "/bin:/usr/bin" # GNU/Linux Etc.confstr(Etc::CS_GNU_LIBC_VERSION) #=> "glibc 2.18" Etc.confstr(Etc::CS_GNU_LIBPTHREAD_VERSION) #=> "NPTL 2.18"
The standard configuration object for gems.
Use the given configuration object (which implements the ConfigFile protocol) as the standard configuration object.
Iterates over strongly connected component in the subgraph reachable from node.
Return value is unspecified.
each_strongly_connected_component_from doesn’t call tsort_each_node.
class G include TSort def initialize(g) @g = g end def tsort_each_child(n, &b) @g[n].each(&b) end def tsort_each_node(&b) @g.each_key(&b) end end graph = G.new({1=>[2, 3], 2=>[4], 3=>[2, 4], 4=>[]}) graph.each_strongly_connected_component_from(2) {|scc| p scc } #=> [4] # [2] graph = G.new({1=>[2], 2=>[3, 4], 3=>[2], 4=>[]}) graph.each_strongly_connected_component_from(2) {|scc| p scc } #=> [4] # [2, 3]
Iterates over strongly connected components in a graph. The graph is represented by node and each_child.
node is the first node. each_child should have call method which takes a node argument and yields for each child node.
Return value is unspecified.
TSort.each_strongly_connected_component_from is a class method and it doesn’t need a class to represent a graph which includes TSort.
graph = {1=>[2], 2=>[3, 4], 3=>[2], 4=>[]} each_child = lambda {|n, &b| graph[n].each(&b) } TSort.each_strongly_connected_component_from(1, each_child) {|scc| p scc } #=> [4] # [2, 3] # [1]
Returns a new array containing the elements of self in reverse order:
[0, 1, 2].reverse # => [2, 1, 0]
Related: see Methods for Combining.
Reverses the order of the elements of self; returns self:
a = [0, 1, 2] a.reverse! # => [2, 1, 0] a # => [2, 1, 0]
Related: see Methods for Assigning.
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 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 a new string with the characters from self in reverse order.
'stressed'.reverse # => "desserts"
Returns self with its characters reversed:
s = 'stressed' s.reverse! # => "desserts" s # => "desserts"
