Results for: "String# "

Specifies the handling of signals. The first parameter is a signal name (a string such as “SIGALRM”, “SIGUSR1”, and so on) or a signal number. The characters “SIG” may be omitted from the signal name. The command or block specifies code to be run when the signal is raised. If the command is the string “IGNORE” or “SIG_IGN”, the signal will be ignored. If the command is “DEFAULT” or “SIG_DFL”, the Ruby’s default handler will be invoked. If the command is “EXIT”, the script will be terminated by the signal. If the command is “SYSTEM_DEFAULT”, the operating system’s default handler will be invoked. Otherwise, the given command or block will be run. The special signal name “EXIT” or signal number zero will be invoked just prior to program termination. trap returns the previous handler for the given signal.

Signal.trap(0, proc { puts "Terminating: #{$$}" })
Signal.trap("CLD")  { puts "Child died" }
fork && Process.wait

produces:

Terminating: 27461
Child died
Terminating: 27460

Writes the file containing the arguments for building this gem’s extensions.

Return the best specification that contains the file matching path amongst the specs that are not activated.

Add the install/update options to the option parser.

Find cached filename in Gem.path. Returns nil if the file cannot be found.

Looks up the latest specification for dependency and adds it to the always_install list.

Get the start index in the Instruction Sequence that corresponds to this YJIT::Block

Rewinds the enumerator chain by calling the “rewind” method on each enumerable in reverse order. Each call is performed only if the enumerable responds to the method.

Returns a printable version of the enumerator chain.
