Returns a new closure wrapper for the name function.
ctype is the return type of the function
argtype is an Array of arguments, passed to the callback function
call_type is the abi of the closure
block is passed to the callback
See Fiddle::Closure
Parse uri into a [uri, option] pair.
The DRbProtocol module asks each registered protocol in turn to try to parse the URI. Each protocol signals that it does not handle that URI by raising a DRbBadScheme error. If no protocol recognises the URI, then a DRbBadURI error is raised.

Terminates the RubyGems process with the given exit_code
Stop tracing object allocations.
Note that if ::trace_object_allocations_start is called n-times, then tracing will stop after calling ::trace_object_allocations_stop n-times.
Returns the birth time for stat.
If the platform doesn’t have birthtime, raises NotImplementedError.
File.write("testfile", "foo") sleep 10 File.write("testfile", "bar") sleep 10 File.chmod(0644, "testfile") sleep 10 File.read("testfile") File.stat("testfile").birthtime #=> 2014-02-24 11:19:17 +0900 File.stat("testfile").mtime #=> 2014-02-24 11:19:27 +0900 File.stat("testfile").ctime #=> 2014-02-24 11:19:37 +0900 File.stat("testfile").atime #=> 2014-02-24 11:19:47 +0900
Creates a new package that will read or write to the file gem.
Sanitize the descriptive fields in the spec. Sometimes non-ASCII characters will garble the site index. Non-ASCII characters will be replaced by their XML entity equivalent.
Returns a new Array that is the union of self and all given Arrays other_arrays; duplicates are removed; order is preserved; items are compared using eql?:
[0, 1, 2, 3].union([4, 5], [6, 7]) # => [0, 1, 2, 3, 4, 5, 6, 7] [0, 1, 1].union([2, 1], [3, 1]) # => [0, 1, 2, 3] [0, 1, 2, 3].union([3, 2], [1, 0]) # => [0, 1, 2, 3]
Returns a copy of self if no arguments given.
Related: Array#|.
Calls the given block self times with each integer in (0..self-1):
a = [] 5.times {|i| a.push(i) } # => 5 a # => [0, 1, 2, 3, 4]
With no block given, returns an Enumerator.
Returns true if self is less than 0, false otherwise.
Returns true if float is less than 0.
Returns the last access time for the named file as a Time object.
file_name can be an IO object.
File.atime("testfile") #=> Wed Apr 09 08:51:48 CDT 2003
Returns the modification time for the named file as a Time object.
file_name can be an IO object.
File.mtime("testfile") #=> Tue Apr 08 12:58:04 CDT 2003
Returns the change time for the named file (the time at which directory information about the file was changed, not the file itself).
file_name can be an IO object.
Note that on Windows (NTFS), returns creation time (birth time).
File.ctime("testfile") #=> Wed Apr 09 08:53:13 CDT 2003
Sets the access and modification times of each named file to the first two arguments. If a file is a symlink, this method acts upon its referent rather than the link itself; for the inverse behavior see File.lutime. Returns the number of file names in the argument list.
Sets the access and modification times of each named file to the first two arguments. If a file is a symlink, this method acts upon the link itself as opposed to its referent; for the inverse behavior, see File.utime. Returns the number of file names in the argument list.
Returns the last access time (a Time object) for file, or epoch if file has not been accessed.
File.new("testfile").atime #=> Wed Dec 31 18:00:00 CST 1969
Returns the modification time for file.
File.new("testfile").mtime #=> Wed Apr 09 08:53:14 CDT 2003
Returns the change time for file (that is, the time directory information about the file was changed, not the file itself).
Note that on Windows (NTFS), returns creation time (birth time).
File.new("testfile").ctime #=> Wed Apr 09 08:53:14 CDT 2003
