Ruby does , persistant storage is made available through the PStore class in
the base library.
Example:
require "pstore"
class T
def initialize(val, left=nil, right=nil)
@val, @left, @right = val, left, right
end
def to_a
[ @val, @left.to_a, @right.to_a ]
end
end
store = PStore.new("/tmp/store")
# store some data
store.transaction do
store['names'] = [ 'Douglas', 'Barenberg', 'Meyer' ]
store['tree'] = T.new('top',
T.new('A', T.new('B')),
T.new('C', T.new('D', nil, T.new('E'))))
end
# now read it back in
store.transaction do
puts "Roots: #{store.roots.join(', ')}"
puts store['names'].join(', ')
puts store['tree'].to_a.inspect
end
I'm not sure about python, but the newest version of ruby (1.8) has an
intergrated http server library with it makes it easy to write servlet type
apps. Here's a simple servlet:
#!/usr/local/bin/ruby
require 'webrick'
include WEBrick
s = HTTPServer.new( :Port => 2000 )
s.mount_proc("/hello"){|req, res|
res.body = "<HTML>hello world</HTML>"
res['Content-Type'] = "text/html"
}trap("INT"){ s.shutdown }
s.start
This way you could eliminate apache as a dependancy.
