Returns the last access time for this file as an object of class Time.
File.stat("testfile").atime #=> Wed Dec 31 18:00:00 CST 1969
Returns true if the file is a character device, false if it isn’t or if the operating system doesn’t support this feature.
File.stat("/dev/tty").chardev? #=> true
Iterates over keys and objects in a weakly referenced object
Returns the path of this instruction sequence.
<compiled> if the iseq was evaluated from a string.
For example, using irb:
iseq = RubyVM::InstructionSequence.compile('num = 1 + 2') #=> <RubyVM::InstructionSequence:<compiled>@<compiled>> iseq.path #=> "<compiled>"
Using ::compile_file:
# /tmp/method.rb
def hello
puts "hello, world"
end
# in irb
> iseq = RubyVM::InstructionSequence.compile_file('/tmp/method.rb')
> iseq.path #=> /tmp/method.rb
The platform this gem runs on.
This is usually Gem::Platform::RUBY or Gem::Platform::CURRENT.
Most gems contain pure Ruby code; they should simply leave the default value in place. Some gems contain C (or other) code to be compiled into a Ruby “extension”. The gem should leave the default value in place unless the code will only compile on a certain type of system. Some gems consist of pre-compiled code (“binary gems”). It’s especially important that they set the platform attribute appropriately. A shortcut is to set the platform to Gem::Platform::CURRENT, which will cause the gem builder to set the platform to the appropriate value for the system on which the build is being performed.
If this attribute is set to a non-default value, it will be included in the filename of the gem when it is built such as: nokogiri-1.6.0-x86-mingw32.gem
Usage:
spec.platform = Gem::Platform.local
Enumerate every known spec. See ::dirs= and ::add_spec to set the list of specs.
Return a list of all outdated local gem names. This method is HEAVY as it must go fetch specifications from the server.
Use outdated_and_latest_version if you wish to retrieve the latest remote version as well.
Activate this spec, registering it as a loaded spec and adding it’s lib paths to $LOAD_PATH. Returns true if the spec was activated, false if it was previously activated. Freaks out if there are conflicts upon activation.
Abbreviate the spec for downloading. Abbreviated specs are only used for searching, downloading and related activities and do not need deployment specific information (e.g. list of files). So we abbreviate the spec, making it much smaller for quicker downloads.
The date this gem was created.
If SOURCE_DATE_EPOCH is set as an environment variable, use that to support reproducible builds; otherwise, default to the current UTC date.

The date this gem was created
DO NOT set this, it is set automatically when the gem is packaged.
Normalize the list of files so that:
All file lists have redundancies removed.
Files referenced in the extra_rdoc_files are included in the package file list.
The platform this gem runs on. See Gem::Platform for details.
A short summary of this gem’s description.
Checks that the specification contains all required fields, and does a very basic sanity check.
Raises InvalidSpecificationException if the spec does not pass the checks..
Factory method to create a Gem::Requirement object. Input may be a Version, a String, or nil. Intended to simplify client code.
If the input is “weird”, the default version requirement is returned.
Concatenates the new requirements onto this requirement.
Store session data on the server. For some session storage types, this is a no-op.
Yields each pair of the row as header and field tuples (much like iterating over a Hash). This method returns the row for chaining.
If no block is given, an Enumerator is returned.
Support for Enumerable.
In the default mixed mode or row mode, iteration is the standard row major walking of rows. In column mode, iteration will yield two element tuples containing the column name and an Array of values for that column.
This method returns the table for chaining.
If no block is given, an Enumerator is returned.
