make nodes in large data structures align on 16-byte bounderies, you can fill a cache line with one read, plus use the segment registers to point to the one you want, then optimise by hardcoding the offsets for each field

can't you just pass a block to the iterator instead of doing scrub poo poo like writing your own loops?

code:

i = (1..5).each #=> #<Enumerator: 1..5:each>
i.each {|n| puts n }
# prints:

Some things just require a lot of code

yeah but not a million lines

the examples are always poo poo like controllers for physical processes (automotive ECUs, rocketry controllers, etc) but behind the "million lines of C" is a few thousand lines of matlab or something that actually compiles to the million lines

facebook compiles to 1.5gb of binary but you can bet it's not anywhere near 1.5gb of php source or even 1.5gb of C++ intermediate code

what you have to do is design a language that makes solving your problem succinct and straightforward, and it turns out java and xml are not that language

eh assuming that reads "print all members of this set" that seems like good syntax to me

it implicitly calls to_a (to array) on the range 1..5, expands it out into multiple arguments, and calls puts with them

code:

(1..5).map(&:even?) #=> [false, true, false, true, false]

casts the symbol :even? to a proc {|x| x.even? }, calls it with each entry in the range 1..5, and returns an array of the results

Mr Dog posted:

also if you really wanted to abuse iterators for I/O (let's make these completely different things look exactly the same) then you'd probably make next() block or something and only make has_next() return false on EOF.

these are kind of the same thing though and it enables some cool stuff!

the "rack" http server protocol for ruby only requires that the response body respond to "each" and yield only String values to the block passed in to each

this means that regardless if your app is going to respond with "butts" or if it's going to stream a thing over a network you don't have to have the upstream app server know what's coming out (in the first case, the array of one string ["butts"]; in the second case, some kind of TCPSocket) or necessarily have your app buffer things

think of it as a duck-typed http://docs.oracle.com/javase/6/docs/api/java/io/Reader.html

rotor posted:

finding the end of an array is an exceptional condition

so what you're saying is that it works best if the enumeration loop knows what it's enumerating over, so you can have one version for arrays and other bounded collections and one for IO that reads until exhausted, but both present the same API to higher-level code so you don't have to care?

this is how python works, fyi

the api they're complaining about is the one for IO

nah they're at a lower level if they have to worry about exceptions from the array ending

or does python have some kind of __~^each^~__(array, lambda{but only one expression}) function with a terrible name and tenuous object-orientedness?

# ¿ May 18, 2012 17:09

Cocoa Crispies: Jul 20, 2001; Vehicular Manslaughter!; Pillbug

Janin posted:

And why would you ever want a lambda with more than one expression? If you really need to use statements in a loop for some horrible reason, just define a local procedure.

Because using lambdas/blocks/anonymous functions as a building block for control structures is convenient

code:

class CalculatorTest < Test::Unit::TestCase
  context "a calculator" do
    setup do
      @calculator = Calculator.new
    end

    should "add two numbers for the sum" do
      assert_equal 4, @calculator.sum(2, 2)
    end

    should "multiply two numbers for the product" do
      assert_equal 10, @calculator.product(2, 5)
    end
  end
end

In Python, it's more idiomatic to use existing control structures like 'if' or 'with', rather than inventing your own ad-hoc.

Oh yeah, Ruby doesn't have "with" built-in; implementing it is an exercise for the reader https://github.com/meh/ruby-with/blob/master/lib/with.rb

What book/resource would you recommend for learning the details of ruby? It seems like a really cool language and I only know the basics atm

i never really used a book or a blog post about "metaprogramming"

work with some libraries that use ruby cleverly and read their source

if in doubt read the C source or the rubinius (ruby in ruby) source
