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")

The standard configuration object for gems.
Use the given configuration object (which implements the ConfigFile protocol) as the standard configuration object.
Returns an Array of sources to fetch remote gems from. Uses default_sources if the sources list is empty.
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.
Performs a Miller-Rabin probabilistic primality test with checks iterations. If nchecks is not specified, a number of iterations is used that yields a false positive rate of at most 2^-80 for random input.
checks - integer

Returns true if stat is writable by the effective user id of this process.
File.stat("testfile").writable? #=> true
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
Produces the summary text. Each line of the summary is yielded to the block (without newline).
sdone
Already summarized short style options keyed hash.
ldone
Already summarized long style options keyed hash.
width
Width of left side (option part). In other words, the right side (description part) starts after width columns.
max
Maximum width of left side -> the options are filled within max columns.
indent
Prefix string indents all summarized lines.
Creates the summary table, passing each line to the block (without newline). The arguments args are passed along to the summarize method which is called on every option.
