Return an array of CodeLines in the document
Example:
combination([:a, :b, :c, :d]) # => [[:a], [:b], [:c], [:d], [:a, :b], [:a, :c], [:a, :d], [:b, :c], [:b, :d], [:c, :d], [:a, :b, :c], [:a, :b, :d], [:a, :c, :d], [:b, :c, :d], [:a, :b, :c, :d]]
v
Public setter for the host component v
(with validation).
See also URI::Generic.check_host
.
require 'uri' uri = URI.parse("http://my.example.com") uri.host = "foo.com" uri.to_s #=> "http://foo.com"
Extract the host part of the URI
and unwrap brackets for IPv6 addresses.
This method is the same as URI::Generic#host
except brackets for IPv6 (and future IP) addresses are removed.
uri = URI("http://[::1]/bar") uri.hostname #=> "::1" uri.host #=> "[::1]"
Sets the host part of the URI
as the argument with brackets for IPv6 addresses.
This method is the same as URI::Generic#host=
except the argument can be a bare IPv6 address.
uri = URI("http://foo/bar") uri.hostname = "::1" uri.to_s #=> "http://[::1]/bar"
If the argument seems to be an IPv6 address, it is wrapped with brackets.
str
String
to search
schemes
Patterns to apply to str
Attempts to parse and merge a set of URIs. If no block
given, then returns the result, else it calls block
for each element in result.
See also URI::Parser.make_regexp.
Deprecated, used YAML::DBM#key
instead.
Note: YAML::DBM#index
makes warning from internal of ::DBM#index. It says ‘DBM#index is deprecated; use DBM#key
’, but DBM#key
behaves not same as DBM#index
.
Returns a Hash
(not a DBM
database) created by using each value in the database as a key, with the corresponding key as its value.
Note that all values in the hash will be Strings, but the keys will be actual objects.
Stores value
in database with key
as the index. value
is converted to YAML
before being stored.
Returns value
Returns a string representation of self
:
system("false") $?.inspect # => "#<Process::Status: pid 1303494 exit 1>"
Returns true
if this process is stopped, and if the corresponding wait call had the Process::WUNTRACED flag set, false
otherwise.
Returns the number of the signal that caused the process to stop, or nil
if the process is not stopped.
Returns the least significant eight bits of the return code of the process if it has exited; nil
otherwise:
`exit 99` $?.exitstatus # => 99
Wakes up all threads waiting for this lock.
