= devnull
http://github.com/maraigue/devnull
Ruby implementation of null file (like /dev/null on Un*x, NUL on Windows)
== DESCRIPTION:
DevNull behaves a null file, and works like an IO object. For example:
dn = DevNull.new
dn.puts "foo" # => nil (do nothing)
dn.gets # => nil
dn.read # => ""
The library may be a good solution if you would like to switch whether an input/output file is needed. For example:
def some_process(arg, logfile = nil)
# You may set an IO object as 'logfile', and logs are written to the file.
result = process1(arg)
logfile.puts result if logfile
result = process2(arg)
logfile.puts result if logfile
result = process3(arg)
logfile.puts result if logfile
end
can be rewritten as follows:
def some_process(arg, logfile = DevNull.new)
logfile.puts process1(arg)
logfile.puts process2(arg)
logfile.puts process3(arg)
end
== INSTALL:
gem install devnull
== DEVELOPERS:
After checking out the source, run:
$ rake newb
This task will install any missing dependencies, run the tests/specs,
and generate the RDoc.
