Returns the Ruby source filename and line number of the binding object.
Raises PStore::Error if the calling code is not in a PStore#transaction.
Returns the Ruby source filename and line number containing this proc or nil if this proc was not defined in Ruby (i.e. native).
Returns the Ruby source filename and line number containing this method or nil if this method was not defined in Ruby (i.e. native).
Returns the Ruby source filename and line number containing this method or nil if this method was not defined in Ruby (i.e. native).
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.
Returns the exception raised on the :raise event or rescued on the :rescue event.
Returns the compiled instruction sequence represented by a RubyVM::InstructionSequence instance on the :script_compiled event.
Note that this method is CRuby-specific.
Returns the current execution stack—an array containing backtrace location objects.
See Thread::Backtrace::Location for more information.
The optional start parameter determines the number of initial stack entries to omit from the top of the stack.
A second optional length parameter can be used to limit how many entries are returned from the stack.
Returns nil if start is greater than the size of current execution stack.
Optionally you can pass a range, which will return an array containing the entries within the specified range.
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.
Returns the original line from source for from the given object.
See ::trace_object_allocations for more information and examples.
Returns true if method mid accepts the given option opt, false otherwise; the arguments may be strings or symbols:
FileUtils.have_option?(:chmod, :noop) # => true FileUtils.have_option?('chmod', 'secure') # => false
Returns an array of the string keyword name for method mid; the argument may be a string or a symbol:
FileUtils.options_of(:rm) # => ["force", "noop", "verbose"] FileUtils.options_of('mv') # => ["force", "noop", "verbose", "secure"]
Returns the convertible integer type of the given type. You may optionally specify additional headers to search in for the type. convertible means actually the same type, or typedef’d from the same type.
If the type is an integer type and the convertible type is found, the following macros are passed as preprocessor constants to the compiler using the type name, in uppercase.
TYPEOF_, followed by the type name, followed by =X where “X” is the found convertible type name.
TYP2NUM and NUM2TYP, where TYP is the type name in uppercase with replacing an _t suffix with “T”, followed by =X where “X” is the macro name to convert type to an Integer object, and vice versa.
For example, if foobar_t is defined as unsigned long, then convertible_int("foobar_t") would return “unsigned long”, and define these macros:
#define TYPEOF_FOOBAR_T unsigned long #define FOOBART2NUM ULONG2NUM #define NUM2FOOBART NUM2ULONG
Convert the given options into a serialized options string.
Returns true if self is greater than 0, false otherwise.
Returns true if self is greater than 0, false otherwise.
Returns the birth time for the named file.
file_name can be an IO object.
File.birthtime("testfile") #=> Wed Apr 09 08:53:13 CDT 2003
If the platform doesn’t have birthtime, raises NotImplementedError.
Returns the birth time for file.
File.new("testfile").birthtime #=> Wed Apr 09 08:53:14 CDT 2003
If the platform doesn’t have birthtime, raises NotImplementedError.
Checks the compatibility of two objects.
If the objects are both strings they are compatible when they are concatenatable. The encoding of the concatenated string will be returned if they are compatible, nil if they are not.
Encoding.compatible?("\xa1".force_encoding("iso-8859-1"), "b") #=> #<Encoding:ISO-8859-1> Encoding.compatible?( "\xa1".force_encoding("iso-8859-1"), "\xa1\xa1".force_encoding("euc-jp")) #=> nil
If the objects are non-strings their encodings are compatible when they have an encoding and:
Either encoding is US-ASCII compatible
One of the encodings is a 7-bit encoding
Returns true if rat is greater than 0.
Returns the birth time for the file. If the platform doesn’t have birthtime, raises NotImplementedError.
See File.birthtime.
Sets the process title that appears on the ps(1) command. Not necessarily effective on all platforms. No exception will be raised regardless of the result, nor will NotImplementedError be raised even if the platform does not support the feature.
Calling this method does not affect the value of $0.
Process.setproctitle('myapp: worker #%d' % worker_id)
This method first appeared in Ruby 2.1 to serve as a global variable free means to change the process title.
