Results for: "Array"

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.
}

The mode needed to read a file as straight binary.

Reset the dir and path values. The next time dir or path is requested, the values will be calculated from scratch. This is mainly used by the unit tests to provide test isolation.

The version of the Marshal format for your Ruby.

Safely read a file in binary mode on all platforms.

Safely write a file in binary mode on all platforms.

Is this platform Solaris?

Interpolate substition vars in the arg (i.e. $(DEFFILE))

Parses the current JSON text source and returns the complete data structure as a result.

Creates a new DH instance from scratch by generating random parameters and a key pair.

See also OpenSSL::PKey.generate_parameters and OpenSSL::PKey.generate_key.

size

The desired key size in bits.

generator

The generator.

Creates a new DSA instance by generating a private/public key pair from scratch.

See also OpenSSL::PKey.generate_parameters and OpenSSL::PKey.generate_key.

size

The desired key size in bits.

Creates a new EC instance with a new random private and public key.

Generates an RSA keypair.

See also OpenSSL::PKey.generate_key.

size

The desired key size in bits.

exponent

An odd Integer, normally 3, 17, or 65537.

Returns the error code of stctx. This is typically called after verify is done, or from the verification callback set to OpenSSL::X509::Store#verify_callback=.

See also the man page X509_STORE_CTX_get_error(3).

Sets the error code of stctx. This is used by the verification callback set to OpenSSL::X509::Store#verify_callback=.

See also the man page X509_STORE_CTX_set_error(3).

Used primarily to check if an OpenSSL::X509::Certificate#public_key compares to its private key.

Example

x509 = OpenSSL::X509::Certificate.new(pem_encoded_certificate)
rsa_key = OpenSSL::PKey::RSA.new(pem_encoded_private_key)

rsa_key.compare?(x509.public_key) => true | false
