Replaces existing options with those given by arguments
, which have the same form as the arguments to ::new
; returns self
.
Raises an exception if option processing has begun.
Returns the Ruby source filename and line number of the binding object.
Returns additional info.
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.
Value from exception raised on the :raise
event
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
.
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 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.
Sets the preset dictionary and returns string
. This method is available just only after a Zlib::NeedDict
exception was raised. See zlib.h for details.
