Returns the Ruby source filename and line number of the binding object.
List of options that will be supplied to RDoc
Value from exception raised on the :raise event
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 original line from source for from the given object.
See ::trace_object_allocations for more information and examples.
Returns the number of malloc() allocations.
Only available if ruby was built with CALC_EXACT_MALLOC_SIZE.
def_exception(n, m, s)
n: exception_name
m: message_form
s: superclass(default: StandardError)
define exception named ``c'' with message m.
Returns true if the method mid have an option opt.
p FileUtils.have_option?(:cp, :noop) #=> true p FileUtils.have_option?(:rm, :force) #=> true p FileUtils.have_option?(:rm, :preserve) #=> false
Returns an Array of option names of the method mid.
p FileUtils.options_of(:rm) #=> ["noop", "verbose", "force"]
Returns whether or not the function func can be found in the common header files, or within any headers that you provide. If found, a macro is passed as a preprocessor constant to the compiler using the function name, in uppercase, prepended with HAVE_.
To check functions in an additional library, you need to check that library first using have_library(). The func shall be either mere function name or function name with arguments.
For example, if have_func('foo') returned true, then the HAVE_FOO preprocessor macro would be passed to the compiler.
True if the gems in the system satisfy dependency.
Add the –version option to the option parser.
Sets the preset dictionary and returns string. This method is available just only after Zlib::Deflate.new or Zlib::ZStream#reset method was called. See zlib.h for details.
Can raise errors of Z_STREAM_ERROR if a parameter is invalid (such as NULL dictionary) or the stream state is inconsistent, Z_DATA_ERROR if the given dictionary doesn’t match the expected one (incorrect adler32 value)
Provide the inflate stream with a dictionary that may be required in the future. Multiple dictionaries may be provided. The inflate stream will automatically choose the correct user-provided dictionary based on the stream’s required dictionary.
