Returns a Process::Status
object representing the most recently exited child process in the current thread, or nil
if none:
Process.spawn('ruby', '-e', 'exit 13') Process.wait Process.last_status # => #<Process::Status: pid 14396 exit 13> Process.spawn('ruby', '-e', 'exit 14') Process.wait Process.last_status # => #<Process::Status: pid 4692 exit 14> Process.spawn('ruby', '-e', 'exit 15') # 'exit 15' has not been reaped by #wait. Process.last_status # => #<Process::Status: pid 4692 exit 14> Process.wait Process.last_status # => #<Process::Status: pid 1380 exit 15>
If the ordering field is missing, or if the ordering field is present and set to false, then the genTime field only indicates the time at which the time-stamp token has been created by the TSA. In such a case, the ordering of time-stamp tokens issued by the same TSA or different TSAs is only possible when the difference between the genTime of the first time-stamp token and the genTime of the second time-stamp token is greater than the sum of the accuracies of the genTime for each time-stamp token.
If the ordering field is present and set to true, every time-stamp token from the same TSA can always be ordered based on the genTime field, regardless of the genTime accuracy.
Enables or disables padding. By default encryption operations are padded using standard block padding and the padding is checked and removed when decrypting. If the pad parameter is zero then no padding is performed, the total amount of data encrypted or decrypted must then be a multiple of the block size or an error will occur.
See EVP_CIPHER_CTX_set_padding for further information.
Returns an array of currently loaded engines.
Creates a new Socket::Option
object for SOL_SOCKET/SO_LINGER.
onoff should be an integer or a boolean.
secs should be the number of seconds.
p Socket::Option.linger(true, 10) #=> #<Socket::Option: UNSPEC SOCKET LINGER on 10sec>
Returns the linger data in sockopt as a pair of boolean and integer.
sockopt = Socket::Option.linger(true, 10) p sockopt.linger => [true, 10]

Returns the origin for an HTTP
uri, as defined in www.rfc-editor.org/rfc/rfc6454.
Example:
URI::HTTP.build(host: 'www.example.com', path: '/foo/bar').origin #=> "http://www.example.com" URI::HTTP.build(host: 'www.example.com', port: 8000, path: '/foo/bar').origin #=> "http://www.example.com:8000" URI::HTTP.build(host: 'www.example.com', port: 80, path: '/foo/bar').origin #=> "http://www.example.com" URI::HTTPS.build(host: 'www.example.com', path: '/foo/bar').origin #=> "https://www.example.com"
Returns the encoding of the source code, which is set by parameters to the parser or by the encoding magic comment.
Returns the encoding of the source code that was parsed.
Return the authoritative instance of the command manager.
Returns self. Allows a CommandManager
instance to stand in for the class itself.
Installs the gem dep_or_name
and all its dependencies. Returns an Array
of installed gem specifications.
If the :prerelease
option is set and there is a prerelease for dep_or_name
the prerelease version will be installed.
Unless explicitly specified as a prerelease dependency, prerelease gems that dep_or_name
depend on will not be installed.
If c-1.a depends on b-1 and a-1.a and there is a gem b-1.a available then c-1.a, b-1 and a-1.a will be installed. b-1.a will need to be installed separately.
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.
Installs the gem and returns a loaded Gem::Specification
for the installed gem.
The gem will be installed with the following structure:
@gem_home/ cache/<gem-version>.gem #=> a cached copy of the installed gem gems/<gem-version>/... #=> extracted files specifications/<gem-version>.gemspec #=> the Gem::Specification
Installs gems for this RequestSet
using the Gem::Installer
options
.
If a block
is given an activation request
and installer
are yielded. The installer
will be nil
if a gem matching the request was already installed.
Performs the uninstall of the gem. This removes the spec, the Gem
directory, and the cached .gem file.
Returns an array of missing elements
For example this:
ExplainSyntax.new(code_lines: lines).missing # => ["}"]
Would indicate that the source is missing a ‘}` character in the source code
Returns an array of missing syntax characters or ‘“end”` or `“keyword”`
left_right.missing # => ["}"]
Sets userinfo, argument is string like ‘name:pass’.
