Sets the system_path
that new instances of Shell
should have as their initial system_path.
path
should be an array of directory name strings.
Returns the value of a thread local variable that has been set. Note that these are different than fiber local values. For fiber local values, please see Thread#[]
and Thread#[]=
.
Thread
local values are carried along with threads, and do not respect fibers. For example:
Thread.new { Thread.current.thread_variable_set("foo", "bar") # set a thread local Thread.current["foo"] = "bar" # set a fiber local Fiber.new { Fiber.yield [ Thread.current.thread_variable_get("foo"), # get the thread local Thread.current["foo"], # get the fiber local ] }.resume }.join.value # => ['bar', nil]
The value “bar” is returned for the thread local, where nil is returned for the fiber local. The fiber is executed in the same thread, so the thread local values are available.
Sets a thread local with key
to value
. Note that these are local to threads, and not to fibers. Please see Thread#thread_variable_get
and Thread#[]
for more information.
Calls block with two arguments, the item and its index, for each item in enum. Given arguments are passed through to each().
If no block is given, an enumerator is returned instead.
hash = Hash.new %w(cat dog wombat).each_with_index { |item, index| hash[item] = index } hash #=> {"cat"=>0, "dog"=>1, "wombat"=>2}
Iterates the given block for each element with an arbitrary object given, and returns the initially given object.
If no block is given, returns an enumerator.
evens = (1..10).each_with_object([]) { |i, a| a << i*2 } #=> [2, 4, 6, 8, 10, 12, 14, 16, 18, 20]
Sets a list of quote characters which can cause a word break.
Raises NotImplementedError
if the using readline library does not support.
Gets a list of quote characters which can cause a word break.
Raises NotImplementedError
if the using readline library does not support.
Sets a list of characters which can be used to quote a substring of the line. Completion occurs on the entire substring, and within the substring Readline.completer_word_break_characters
are treated as any other character, unless they also appear within this list.
Raises NotImplementedError
if the using readline library does not support.
Gets a list of characters which can be used to quote a substring of the line.
Raises NotImplementedError
if the using readline library does not support.
Sets a list of characters that cause a filename to be quoted by the completer when they appear in a completed filename. The default is nil.
Raises NotImplementedError
if the using readline library does not support.
Gets a list of characters that cause a filename to be quoted by the completer when they appear in a completed filename.
Raises NotImplementedError
if the using readline library does not support.
Verify internal consistency.
This method is implementation specific. Now this method checks generational consistency if RGenGC is supported.
Set
the default id conversion object.
This is expected to be an instance such as DRb::DRbIdConv
that responds to to_id
and to_obj
that can convert objects to and from DRb
references.
See DRbServer#default_id_conv.

Returns the security level for the context.
See also OpenSSL::SSL::SSLContext#security_level=
.
Sets the security level for the context. OpenSSL
limits parameters according to the level. The “parameters” include: ciphersuites, curves, key sizes, certificate signature algorithms, protocol version and so on. For example, level 1 rejects parameters offering below 80 bits of security, such as ciphersuites using MD5 for the MAC or RSA keys shorter than 1024 bits.
Note that attempts to set such parameters with insufficient security are also blocked. You need to lower the level first.
This feature is not supported in OpenSSL
< 1.1.0, and setting the level to other than 0 will raise NotImplementedError
. Level 0 means everything is permitted, the same behavior as previous versions of OpenSSL
.
See the manpage of SSL_CTX_set_security_level(3) for details.
Initiates the SSL/TLS handshake as a server in non-blocking manner.
# emulates blocking accept begin ssl.accept_nonblock rescue IO::WaitReadable IO.select([s2]) retry rescue IO::WaitWritable IO.select(nil, [s2]) retry end
By specifying a keyword argument exception to false
, you can indicate that accept_nonblock
should not raise an IO::WaitReadable
or IO::WaitWritable
exception, but return the symbol :wait_readable
or :wait_writable
instead.
A non-blocking version of sysread
. Raises an SSLError
if reading would block. If “exception: false” is passed, this method returns a symbol of :wait_readable, :wait_writable, or nil, rather than raising an exception.
Reads length bytes from the SSL
connection. If a pre-allocated buffer is provided the data will be written into it.
