Look up the typeclass DNS resource of name.
name must be a Resolv::DNS::Name or a String.
typeclass should be one of the following:
Resolv::DNS::Resource::IN::ANY
Resolv::DNS::Resource::IN::CNAME
Resolv::DNS::Resource::IN::HINFO
Resolv::DNS::Resource::IN::MINFO
Resolv::DNS::Resource::IN::MX
Resolv::DNS::Resource::IN::NS
Resolv::DNS::Resource::IN::PTR
Resolv::DNS::Resource::IN::SOA
Resolv::DNS::Resource::IN::TXT
Returned resource is represented as a Resolv::DNS::Resource instance, i.e. Resolv::DNS::Resource::IN::A.
Looks up all typeclass DNS resources for name. See getresource for argument details.
Adds tuple to the proxied TupleSpace. See TupleSpace#write.
Returns the first advertised TupleSpace.

Writes out this config file, replacing its source.
Changes in rubygems to lazily loading ‘rubygems/command` (in order to lazily load `optparse` as a side effect) affect bundler’s custom installer which uses ‘Gem::Command` without requiring it (up until bundler 2.2.29). This hook is to compensate for that missing require.
TODO: Remove when rubygems no longer supports running on bundler older than 2.2.29.

Writes s to the stream. If the argument is not a String it will be converted using .to_s method. Returns the number of bytes written.
Formats and writes to the stream converting parameters under control of the format string.
See Kernel#sprintf for format string details.
Generate a random alphanumeric string.
The argument n specifies the length, in characters, of the alphanumeric string to be generated.
If n is not specified or is nil, 16 is assumed. It may be larger in the future.
The result may contain A-Z, a-z and 0-9.
require 'random/formatter' Random.alphanumeric #=> "2BuBuLf3WfSKyQbR" # or prng = Random.new prng.alphanumeric(10) #=> "i6K93NdqiH"
Writes pemmable, which must respond to to_pem to path with the given permissions. If passed cipher and passphrase those arguments will be passed to to_pem.
Returns the Fiber scheduler, that was last set for the current thread with Fiber.set_scheduler if and only if the current fiber is non-blocking.
Returns true if the named file is writable by the real user and group id of this process. See access(3).
Note that some OS-level security features may cause this to return true even though the file is not writable by the real user/group.
