Get a single optional argument from the command line. If more than one argument is given, return only the first. Return nil if none are given.
Search through all unresolved deps and sub-dependencies and return specs that contain the file matching path
.
Extract platform given on the command line
Returns a relative path from the given base_directory
to the receiver.
If self
is absolute, then base_directory
must be absolute too.
If self
is relative, then base_directory
must be relative too.
This method doesn’t access the filesystem. It assumes no symlinks.
ArgumentError
is raised when it cannot find a relative path.
Note that this method does not handle situations where the case sensitivity of the filesystem in use differs from the operating system default.
Receive UDP/IP packets from the given sockets. For each packet received, the block is called.
The block receives msg and msg_src. msg is a string which is the payload of the received packet. msg_src is a Socket::UDPSource
object which is used for reply.
Socket.udp_server_loop
can be implemented using this method as follows.
udp_server_sockets(host, port) {|sockets| loop { readable, _, _ = IO.select(sockets) udp_server_recv(readable) {|msg, msg_src| ... } } }
Return the native thread ID which is used by the Ruby
thread.
The ID depends on the OS. (not POSIX thread ID returned by pthread_self(3))
On Linux it is TID returned by gettid(2).
On macOS it is the system-wide unique integral ID of thread returned by pthread_threadid_np(3).
On FreeBSD it is the unique integral ID of the thread returned by pthread_getthreadid_np(3).
On Windows it is the thread identifier returned by GetThreadId().
On other platforms, it raises NotImplementedError
.
NOTE: If the thread is not associated yet or already deassociated with a native thread, it returns nil. If the Ruby
implementation uses M:N thread model, the ID may change depending on the timing.
Returns a Hash
containing the following keys:
Number of started SSL/TLS handshakes in server mode
Number of established SSL/TLS sessions in server mode
Number of start renegotiations in server mode
Number of sessions that were removed due to cache overflow
Number of successfully reused connections
Number of sessions proposed by clients that were not found in the cache
Number of sessions in the internal session cache
Number of sessions retrieved from the external cache in server mode
Number of started SSL/TLS handshakes in client mode
Number of established SSL/TLS sessions in client mode
Number of start renegotiations in client mode
Number of sessions proposed by clients that were found in the cache but had expired due to timeouts
Fetch the start character column of the value.
Looks up the latest specification for dependency
and adds it to the always_install list.
Emit a scalar with value
and tag
Emit a sequence with list
and tag
Emit a sequence with map
and tag
Emit an arbitrary object obj
and tag
Returns true
if stat is readable by the real user id of this process.
File.stat("testfile").readable_real? #=> true
Paths in the gem to add to $LOAD_PATH
when this gem is activated.
See also require_paths=
If you have an extension you do not need to add "ext"
to the require path, the extension build process will copy the extension files into “lib” for you.
The default value is "lib"
Usage:
# If all library files are in the root directory... spec.require_path = '.'
Really verbose mode gives you extra output.
