Takes a hash as its argument. The key is a symbol or an array of symbols. These symbols correspond to method names, instance variable names, or constant names (see def_delegator). The value is the accessor to which the methods will be delegated.

Basically a wrapper for Process.spawn that:
Creates a child process for each of the given cmds by calling Process.spawn.
Does not wait for child processes to exit.
With no block given, returns an array of the wait threads for all of the child processes.
Example:
wait_threads = Open3.pipeline_start('ls', 'grep R') # => [#<Process::Waiter:0x000055e8de9d2bb0 run>, #<Process::Waiter:0x000055e8de9d2890 run>] wait_threads.each do |wait_thread| wait_thread.join end
Output:
Rakefile README.md
With a block given, calls the block with an array of the wait processes:
Open3.pipeline_start('ls', 'grep R') do |wait_threads| wait_threads.each do |wait_thread| wait_thread.join end end
Output:
Rakefile README.md
Like Process.spawn, this method has potential security vulnerabilities if called with untrusted input; see Command Injection.
If the first argument is a hash, it becomes leading argument env in each call to Process.spawn; see Execution Environment.
If the last argument is a hash, it becomes trailing argument options in each call to Process.spawn; see Execution Options.
Each remaining argument in cmds is one of:
A command_line: a string that begins with a shell reserved word or special built-in, or contains one or more metacharacters.
An exe_path: the string path to an executable to be called.
An array containing a command_line or an exe_path, along with zero or more string arguments for the command.

Mirror the Prism.parse_stream API by using the serialization API.
Returns a Process::Status object representing the most recently exited child process in the current thread, or nil if none:
Process.spawn('ruby', '-e', 'exit 13') Process.wait Process.last_status # => #<Process::Status: pid 14396 exit 13> Process.spawn('ruby', '-e', 'exit 14') Process.wait Process.last_status # => #<Process::Status: pid 4692 exit 14> Process.spawn('ruby', '-e', 'exit 15') # 'exit 15' has not been reaped by #wait. Process.last_status # => #<Process::Status: pid 4692 exit 14> Process.wait Process.last_status # => #<Process::Status: pid 1380 exit 15>
If the ordering field is missing, or if the ordering field is present and set to false, then the genTime field only indicates the time at which the time-stamp token has been created by the TSA. In such a case, the ordering of time-stamp tokens issued by the same TSA or different TSAs is only possible when the difference between the genTime of the first time-stamp token and the genTime of the second time-stamp token is greater than the sum of the accuracies of the genTime for each time-stamp token.
If the ordering field is present and set to true, every time-stamp token from the same TSA can always be ordered based on the genTime field, regardless of the genTime accuracy.
Enables or disables padding. By default encryption operations are padded using standard block padding and the padding is checked and removed when decrypting. If the pad parameter is zero then no padding is performed, the total amount of data encrypted or decrypted must then be a multiple of the block size or an error will occur.
See EVP_CIPHER_CTX_set_padding for further information.
Returns an array of currently loaded engines.
Creates a new Socket::Option object for SOL_SOCKET/SO_LINGER.
onoff should be an integer or a boolean.
secs should be the number of seconds.
p Socket::Option.linger(true, 10) #=> #<Socket::Option: UNSPEC SOCKET LINGER on 10sec>
Returns the linger data in sockopt as a pair of boolean and integer.
sockopt = Socket::Option.linger(true, 10) p sockopt.linger => [true, 10]

Returns the origin for an HTTP uri, as defined in www.rfc-editor.org/rfc/rfc6454.
Example:
URI::HTTP.build(host: 'www.example.com', path: '/foo/bar').origin #=> "http://www.example.com" URI::HTTP.build(host: 'www.example.com', port: 8000, path: '/foo/bar').origin #=> "http://www.example.com:8000" URI::HTTP.build(host: 'www.example.com', port: 80, path: '/foo/bar').origin #=> "http://www.example.com" URI::HTTPS.build(host: 'www.example.com', path: '/foo/bar').origin #=> "https://www.example.com"
Returns the encoding of the source code, which is set by parameters to the parser or by the encoding magic comment.
Returns the encoding of the source code that was parsed.
Return the authoritative instance of the command manager.
Returns self. Allows a CommandManager instance to stand in for the class itself.
