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.
Unpacks sockaddr into port and ip_address.
sockaddr should be a string or an addrinfo for AF_INET/AF_INET6.
sockaddr = Socket.sockaddr_in(80, "127.0.0.1") p sockaddr #=> "\x02\x00\x00P\x7F\x00\x00\x01\x00\x00\x00\x00\x00\x00\x00\x00" p Socket.unpack_sockaddr_in(sockaddr) #=> [80, "127.0.0.1"]
Unpacks sockaddr into path.
sockaddr should be a string or an addrinfo for AF_UNIX.
sockaddr = Socket.sockaddr_un("/tmp/sock") p Socket.unpack_sockaddr_un(sockaddr) #=> "/tmp/sock"
Initialize WIN32OLE
object(ActiveX Control) by calling IPersistMemory::InitNew.
Before calling OLE method, some kind of the ActiveX controls created with MFC should be initialized by calling IPersistXXX::InitNew.
If and only if you received the exception “HRESULT error code: 0x8000ffff catastrophic failure”, try this method before invoking any ole_method.
obj = WIN32OLE.new("ProgID_or_GUID_of_ActiveX_Control") obj.ole_activex_initialize obj.method(...)
Returns WIN32OLE
object for a specific dispatch or dual interface specified by iid.
ie = WIN32OLE.new('InternetExplorer.Application') ie_web_app = ie.ole_query_interface('{0002DF05-0000-0000-C000-000000000046}') # => WIN32OLE object for dispinterface IWebBrowserApp
This method injects an instance variable unconverted_fields
into row
and an accessor method for row
called unconverted_fields(). The variable is set to the contents of fields
.
Re-composes a prime factorization and returns the product.
See Prime#int_from_prime_division
for more details.
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.
Set
local variable named symbol
as obj
.
def foo a = 1 bind = binding bind.local_variable_set(:a, 2) # set existing local variable `a' bind.local_variable_set(:b, 3) # create new local variable `b' # `b' exists only in binding p bind.local_variable_get(:a) #=> 2 p bind.local_variable_get(:b) #=> 3 p a #=> 2 p b #=> NameError end
This method behaves similarly to the following code:
binding.eval("#{symbol} = #{obj}")
if obj
can be dumped in Ruby code.
obj can be an instance of InternalObjectWrapper
.
Note that you should not use this method in your application.
Attempts to enter exclusive section. Returns false
if lock fails.

Emit a scalar with value
and tag
Emit a sequence with list
and tag
Called when a sequence is started.
anchor
is the anchor associated with the sequence or nil. tag
is the tag associated with the sequence or nil. implicit
a boolean indicating whether or not the sequence was implicitly started. style
is an integer indicating the list style.
See the constants in Psych::Nodes::Sequence
for the possible values of style
.
Here is a YAML document that exercises most of the possible ways this method can be called:
--- - !!seq [ a ] - &pewpew - b
The above YAML document consists of three lists, an outer list that contains two inner lists. Here is a matrix of the parameters sent to represent these lists:
# anchor tag implicit style [nil, nil, true, 1 ] [nil, "tag:yaml.org,2002:seq", false, 2 ] ["pewpew", nil, true, 1 ]
This method is called when a parse error is found.
ERROR_TOKEN_ID is an internal ID of token which caused error. You can get string representation of this ID by calling token_to_str
.
ERROR_VALUE is a value of error token.
value_stack is a stack of symbol values. DO NOT MODIFY this object.
This method raises ParseError
by default.
If this method returns, parsers enter “error recovering mode”.
Duplicates the deflate stream.
Sends a GET request to the target and returns the HTTP
response as a Net::HTTPResponse
object. The target can either be specified as (uri
), or as (host
, path
, port
= 80); so:
res = Net::HTTP.get_response(URI('http://www.example.com/index.html')) print res.body
or:
res = Net::HTTP.get_response('www.example.com', '/index.html') print res.body
Returns the X.509 certificates the server presented.
