Creates a new MonitorMixin::ConditionVariable
associated with the Monitor
object.
Returns garbage collector generation for the given object
.
class B include ObjectSpace def foo trace_object_allocations do obj = Object.new p "Generation is #{allocation_generation(obj)}" end end end B.new.foo #=> "Generation is 3"
See ::trace_object_allocations
for more information and examples.
The RbConfig
object for the deployment target platform.
This is usually the same as the running platform, but may be different if you are cross-compiling.
The path to standard location of the user’s configuration directory.
The path to standard location of the user’s .gemrc file.
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"]
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.
Tests for the presence of a --with-
config or --without-
config option. Returns true
if the with option is given, false
if the without option is given, and the default value otherwise.
This can be useful for adding custom definitions, such as debug information.
Example:
if with_config("debug") $defs.push("-DOSSL_DEBUG") unless $defs.include? "-DOSSL_DEBUG" end
Tests for the presence of an --enable-
config or --disable-
config option. Returns true
if the enable option is given, false
if the disable option is given, and the default value otherwise.
This can be useful for adding custom definitions, such as debug information.
Example:
if enable_config("debug") $defs.push("-DOSSL_DEBUG") unless $defs.include? "-DOSSL_DEBUG" end
Sets a target
name that the user can then use to configure various “with” options with on the command line by using that name. For example, if the target is set to “foo”, then the user could use the --with-foo-dir=prefix
, --with-foo-include=dir
and --with-foo-lib=dir
command line options to tell where to search for header/library files.
You may pass along additional parameters to specify default values. If one is given it is taken as default prefix
, and if two are given they are taken as “include” and “lib” defaults in that order.
In any case, the return value will be an array of determined “include” and “lib” directories, either of which can be nil if no corresponding command line option is given when no default value is specified.
Note that dir_config
only adds to the list of places to search for libraries and include files. It does not link the libraries into your application.
Returns compile/link information about an installed library in a tuple of [cflags, ldflags, libs]
, by using the command found first in the following commands:
If --with-{pkg}-config={command}
is given via command line option: {command} {options}
{pkg}-config {options}
pkg-config {options} {pkg}
Where options
is the option name without dashes, for instance "cflags"
for the --cflags
flag.
The values obtained are appended to $INCFLAGS
, $CFLAGS
, $LDFLAGS
and $libs
.
If one or more options
argument is given, the config command is invoked with the options and a stripped output string is returned without modifying any of the global values mentioned above.
Convert the given options into a serialized options string.
Returns a Process::Status
object representing the most recently exited child process in the current thread, or nil
if none:
Process.spawn('ruby', '-e', 'exit 13') Process.wait Process.last_status # => #<Process::Status: pid 14396 exit 13> Process.spawn('ruby', '-e', 'exit 14') Process.wait Process.last_status # => #<Process::Status: pid 4692 exit 14> Process.spawn('ruby', '-e', 'exit 15') # 'exit 15' has not been reaped by #wait. Process.last_status # => #<Process::Status: pid 4692 exit 14> Process.wait Process.last_status # => #<Process::Status: pid 1380 exit 15>

Get the names of all sections in the current configuration.
Returns help context.
