Open3.pipeline_start starts a list of commands as a pipeline. No pipes are created for stdin of the first command and stdout of the last command.

Open3.pipeline_start(cmd1, cmd2, ... [, opts]) {|wait_threads|
  ...
}

wait_threads = Open3.pipeline_start(cmd1, cmd2, ... [, opts])
...

Each cmd is a string or an array. If it is an array, the elements are passed to Process.spawn.

cmd:
  commandline                              command line string which is passed to a shell
  [env, commandline, opts]                 command line string which is passed to a shell
  [env, cmdname, arg1, ..., opts]          command name and one or more arguments (no shell)
  [env, [cmdname, argv0], arg1, ..., opts] command name and arguments including argv[0] (no shell)

Note that env and opts are optional, as for Process.spawn.

Example:

# Run xeyes in 10 seconds.
Open3.pipeline_start("xeyes") {|ts|
  sleep 10
  t = ts[0]
  Process.kill("TERM", t.pid)
  p t.value #=> #<Process::Status: pid 911 SIGTERM (signal 15)>
}

# Convert pdf to ps and send it to a printer.
# Collect error message of pdftops and lpr.
pdf_file = "paper.pdf"
printer = "printer-name"
err_r, err_w = IO.pipe
Open3.pipeline_start(["pdftops", pdf_file, "-"],
                     ["lpr", "-P#{printer}"],
                     :err=>err_w) {|ts|
  err_w.close
  p err_r.read # error messages of pdftops and lpr.

Starts the profiler.

Adds a post-build hook that will be passed an Gem::Installer instance when Gem::Installer#install is called. The hook is called after the gem has been extracted and extensions have been built but before the executables or gemspec has been written. If the hook returns false then the gem’s files will be removed and the install will be aborted.

Find the ‘rubygems_plugin’ files in the latest installed gems and load them

Redirects to a path ending in /

Full paths in the gem to add to $LOAD_PATH when this gem is activated.

Make directories for index generation

Creates a Resolver that queries only against the already installed gems for the needed dependencies.

Return currently unresolved specs that contain the file matching path.

Expire memoized instance variables that can incorrectly generate, replace or miss files due changes in certain attributes used to compute them.

Given the path to a gem file, validates against its own MD5 checksum

gem_path

String

Path to gem file

Creates a self-signed certificate with an issuer and subject from email, a subject alternative name of email and the given extensions for the key.
