Returns the execution stack for the target thread—an array containing backtrace location objects.
See Thread::Backtrace::Location for more information.
This method behaves similarly to Kernel#caller_locations except it applies to a specific thread.
Value from exception raised on the :raise event
Compiled instruction sequence represented by a RubyVM::InstructionSequence instance on the :script_compiled event.
Note that this method is MRI specific.
Controls tracing of assignments to global variables. The parameter symbol identifies the variable (as either a string name or a symbol identifier). cmd (which may be a string or a Proc object) or block is executed whenever the variable is assigned. The block or Proc object receives the variable’s new value as a parameter. Also see Kernel::untrace_var.
trace_var :$_, proc {|v| puts "$_ is now '#{v}'" } $_ = "hello" $_ = ' there'
produces:
$_ is now 'hello' $_ is now ' there'
Removes tracing for the specified command on the given global variable and returns nil. If no command is specified, removes all tracing for that variable and returns an array containing the commands actually removed.
Initializes the MonitorMixin after being included in a class or when an object has been extended with the MonitorMixin
Returns the source file origin from the given object.
See ::trace_object_allocations for more information and examples.
Adds aProc as a finalizer, to be called after obj was destroyed. The object ID of the obj will be passed as an argument to aProc. If aProc is a lambda or method, make sure it can be called with a single argument.
Removes all finalizers for obj.
Returns the version of libyaml being used
Returns the full line that is being edited. This is useful from within the complete_proc for determining the context of the completion request.
The length of Readline.line_buffer and GNU Readline’s rl_end are same.
Raises NotImplementedError if the using readline library does not support.
Clear the current input line.
Returns the string which represents the version of zlib library.
Returns the Base64-encoded version of bin. This method complies with RFC 4648. No line feeds are added.
Returns the Base64-decoded version of str. This method complies with RFC 4648. ArgumentError is raised if str is incorrectly padded or contains non-alphabet characters. Note that CR or LF are also rejected.
Adds a post-installs hook that will be passed a Gem::DependencyInstaller and a list of installed specifications when Gem::DependencyInstaller#install is complete
An Array of the default sources that come with RubyGems
Hard links a file system entry src to dest. If src is a directory, this method links its contents recursively.
Both of src and dest must be a path name. src must exist, dest must not exist.
If dereference_root is true, this method dereferences the tree root.
If remove_destination is true, this method removes each destination file before copy.

If remove_destination is true, this method removes each destination file before copy.
Takes a hash as its argument. The key is a symbol or an array of symbols. These symbols correspond to method names, instance variable names, or constant names (see def_delegator). The value is the accessor to which the methods will be delegated.
Returns whether or not the given entry point func can be found within lib. If func is nil, the main() entry point is used by default. If found, it adds the library to list of libraries to be used when linking your extension.
If headers are provided, it will include those header files as the header files it looks in when searching for func.
The real name of the library to be linked can be altered by --with-FOOlib configuration option.
Returns whether or not the entry point func can be found within the library lib in one of the paths specified, where paths is an array of strings. If func is nil , then the main() function is used as the entry point.
If lib is found, then the path it was found on is added to the list of library paths searched and linked against.
