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, or rescued on the :rescue
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.
