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.

This lexes with the Ripper lex. It drops any space events but otherwise returns the same tokens. Raises SyntaxError if the syntax in source is invalid.
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>

Returns the human readable error string corresponding to the error code retrieved by error.

This method is provided by the Ripper C extension. It is called when a string needs to be dedented because of a tilde heredoc. It is expected that it will modify the string in place and return the number of bytes that were removed.
