Need to be able to set the sources without calling Gem.sources.replace since that would cause an infinite loop.

DOC: This comment is not documentation about the method itself, it’s more of a code comment about the implementation.

Open3.capture3 captures the standard output and the standard error of a command.

stdout_str, stderr_str, status = Open3.capture3([env,] cmd... [, opts])

The arguments env, cmd and opts are passed to Open3.popen3 except opts[:stdin_data] and opts[:binmode]. See Process.spawn.

If opts[:stdin_data] is specified, it is sent to the command’s standard input.

If opts[:binmode] is true, internal pipes are set to binary mode.

Examples:

# dot is a command of graphviz.
graph = <<'End'
  digraph g {
    a -> b
  }
End
drawn_graph, dot_log = Open3.capture3("dot -v", :stdin_data=>graph)

o, e, s = Open3.capture3("echo abc; sort >&2", :stdin_data=>"foo\nbar\nbaz\n")
p o #=> "abc\n"
p e #=> "bar\nbaz\nfoo\n"
p s #=> #<Process::Status: pid 32682 exit 0>

# generate a thumbnail image using the convert command of ImageMagick.
# However, if the image is really stored in a file,
# system("convert", "-thumbnail", "80", "png:#{filename}", "png:-") is better
# because of reduced memory consumption.
# But if the image is stored in a DB or generated by the gnuplot Open3.capture2 example,
# Open3.capture3 should be considered.
#
image = File.read("/usr/share/openclipart/png/animals/mammals/sheep-md-v0.1.png", :binmode=>true)
thumbnail, err, s = Open3.capture3("convert -thumbnail 80 png:- png:-", :stdin_data=>image, :binmode=>true)
if s.success?
  STDOUT.binmode; print thumbnail
end

Open3.capture2 captures the standard output of a command.

The arguments env, cmd and opts are passed to Open3.popen3 except opts[:stdin_data] and opts[:binmode]. See Process.spawn.

If opts[:binmode] is true, internal pipes are set to binary mode.

Example:

# factor is a command for integer factorization.
o, s = Open3.capture2("factor", :stdin_data=>"42")
p o #=> "42: 2 3 7\n"

# generate x**2 graph in png using gnuplot.
gnuplot_commands = <<"End"
  set terminal png
  plot x**2, "-" with lines
  1 14
  2 1
  3 8
  4 5
  e
End
image, s = Open3.capture2("gnuplot", :stdin_data=>gnuplot_commands, :binmode=>true)

Open3.capture2e captures the standard output and the standard error of a command.

stdout_and_stderr_str, status = Open3.capture2e([env,] cmd... [, opts])

The arguments env, cmd and opts are passed to Open3.popen3 except opts[:stdin_data] and opts[:binmode]. See Process.spawn.

If opts[:stdin_data] is specified, it is sent to the command’s standard input.

If opts[:binmode] is true, internal pipes are set to binary mode.

Example:

# capture make log
make_log, s = Open3.capture2e("make")

If opts[:binmode] is true, internal pipes are set to binary mode.

Example:

# capture make log
make_log, s = Open3.capture2e("make")

Performs a Miller-Rabin probabilistic primality test with checks iterations. If checks is not specified, a number of iterations is used that yields a false positive rate of at most 2^-80 for random input.

Parameters

• checks - integer

Same as IO.

Same as IO.

Same as IO.

Returns true if stat is writable by the effective user id of this process.

File.stat("testfile").writable?   #=> true

Set whether the Cookie is a secure cookie or not.

val must be a boolean.

Symmetric Householder reduction to tridiagonal form.

Sends a SUBSCRIBE command to add the specified mailbox name to the server’s set of “active” or “subscribed” mailboxes as returned by lsub().

A Net::IMAP::NoResponseError is raised if mailbox cannot be subscribed to; for instance, because it does not exist.

Sends a UNSUBSCRIBE command to remove the specified mailbox name from the server’s set of “active” or “subscribed” mailboxes.

A Net::IMAP::NoResponseError is raised if mailbox cannot be unsubscribed from; for instance, because the client is not currently subscribed to it.

returns whether verify_mode is enable from POP3.ssl_params
