“no-default-alpn” SvcParam – No support for default protocol
Raised if a value that could potentially be on an entry is missing because it was either not configured on the repository or it has not yet been fetched.
“alpn” SvcParam – Additional supported protocols
Equivalent to Date#new_start with argument Date::ITALY.
Top level install helper method. Allows you to install gems interactively:
% irb >> Gem.install "minitest" Fetching: minitest-5.14.0.gem (100%) => [#<Gem::Specification:0x1013b4528 @name="minitest", ...>]
Copies a file entry. See install(1).
Arguments src (a single path or an array of paths) and dest (a single path) should be interpretable as paths;
If the entry at dest does not exist, copies from src to dest:
File.read('src0.txt') # => "aaa\n" File.exist?('dest0.txt') # => false FileUtils.install('src0.txt', 'dest0.txt') File.read('dest0.txt') # => "aaa\n"
If dest is a file entry, copies from src to dest, overwriting:
File.read('src1.txt') # => "aaa\n" File.read('dest1.txt') # => "bbb\n" FileUtils.install('src1.txt', 'dest1.txt') File.read('dest1.txt') # => "aaa\n"
If dest is a directory entry, copies from src to dest/src, overwriting if necessary:
File.read('src2.txt') # => "aaa\n" File.read('dest2/src2.txt') # => "bbb\n" FileUtils.install('src2.txt', 'dest2') File.read('dest2/src2.txt') # => "aaa\n"
If src is an array of paths and dest points to a directory, copies each path path in src to dest/path:
File.file?('src3.txt') # => true File.file?('src3.dat') # => true FileUtils.mkdir('dest3') FileUtils.install(['src3.txt', 'src3.dat'], 'dest3') File.file?('dest3/src3.txt') # => true File.file?('dest3/src3.dat') # => true
Keyword arguments:
group: group - changes the group if not nil, using File.chown.
mode: permissions - changes the permissions. using File.chmod.
noop: true - does not copy entries; returns nil.
owner: owner - changes the owner if not nil, using File.chown.
preserve: true - preserve timestamps using File.utime.
verbose: true - prints an equivalent command:
FileUtils.install('src0.txt', 'dest0.txt', noop: true, verbose: true) FileUtils.install('src1.txt', 'dest1.txt', noop: true, verbose: true) FileUtils.install('src2.txt', 'dest2', noop: true, verbose: true)
Output:
install -c src0.txt dest0.txt install -c src1.txt dest1.txt install -c src2.txt dest2

Waits for all children, returns an array of 2-element arrays; each subarray contains the integer pid and Process::Status status for one of the reaped child processes:
pid0 = Process.spawn('ruby', '-e', 'exit 13') # => 325470 pid1 = Process.spawn('ruby', '-e', 'exit 14') # => 325495 Process.waitall # => [[325470, #<Process::Status: pid 325470 exit 13>], [325495, #<Process::Status: pid 325495 exit 14>]]
Adds a post-install hook that will be passed an Gem::Installer instance when Gem::Installer#install is called
Adds a post-installs hook that will be passed a Gem::DependencyInstaller and a list of installed specifications when Gem::DependencyInstaller#install is complete
Adds a post-uninstall hook that will be passed a Gem::Uninstaller instance and the spec that was uninstalled when Gem::Uninstaller#uninstall is called
Adds a pre-install hook that will be passed an Gem::Installer instance when Gem::Installer#install is called. If the hook returns false then the install will be aborted.
Adds a pre-uninstall hook that will be passed an Gem::Uninstaller instance and the spec that will be uninstalled when Gem::Uninstaller#uninstall is called
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.
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
