Returns true if stat is readable by the real user id of this process.
File.stat("testfile").readable_real? #=> true
If stat is readable by others, returns an integer representing the file permission bits of stat. Returns nil otherwise. The meaning of the bits is platform dependent; on Unix systems, see stat(2).
m = File.stat("/etc/passwd").world_readable? #=> 420 sprintf("%o", m) #=> "644"
Returns true if stat is writable by the real user id of this process.
File.stat("testfile").writable_real? #=> true
If stat is writable by others, returns an integer representing the file permission bits of stat. Returns nil otherwise. The meaning of the bits is platform dependent; on Unix systems, see stat(2).
m = File.stat("/tmp").world_writable? #=> 511 sprintf("%o", m) #=> "777"
Same as executable?, but tests using the real owner of the process.
Returns a Gem::StubSpecification for default gems
Loads the default specifications. It should be called only once.
Returns the full path to an executable named name in this gem.
Returns the full path to the cached gem for this spec.
The default value for specification attribute name
The default (generated) file name of the gem. See also spec_name.
spec.file_name # => "example-1.0.gem"

Return a NameTuple that represents this Specification
Return a string containing a Ruby code representation of the given object.
Returns the full path to this spec’s gemspec file. eg: /usr/local/lib/ruby/gems/1.8/specifications/mygem-1.0.gemspec
The provided block is passed a header and field for each pair in the row and expected to return true or false, depending on whether the pair should be deleted.
This method returns the row for chaining.
If no block is given, an Enumerator is returned.
Removes any column or row for which the block returns true. 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.
