Splitting flac and ape files in Debian / Ubuntu

I keep forgetting this one, so I'll keep it here.

What to do when you get a cue file with a single huge flac file, or even worse, an ape file? With the right packages it's an easy task (getting the packages right may be hard tough).

There are three parts to this problem: getting the ape file to a more user friendly format (flac), splitting it and then renaming the splitted files.

Needed packages

wget http://members.iinet.net.au/~aidanjm/mac-3.99-u4_b3-1_i386.deb && 
   sudo dpkg -i mac-3.99-u4_b3-1_i386.deb && 
   rm -f mac-3.99-u4_b3-1_i386.deb

Now install cuetools:

  sudo apt-get install cuetools

Splitting the file

  cuebreakpoints *.cue|shnsplit *.ape -o flac

Renaming the splitted parts

In the cue file there should be a list of the original file names. I hacked a script to parse & rename the files from the previous step, you can get it here: cue-rename

For this script to run you'll need php-cli package. Just run it in the same folder the cue file is, as any other bash script. There's a flag to get a preview instead of a complete rename; it's somewhere in the file and I don't have much plans to clean it up anytime soon. Drop me a line if you do.

Ruby: Method chaining

Interesante :)

#!/usr/bin/ruby1.8

module MethodDecorator
# Create a chain between methods:
#   Rename org_mthd to org_alias and then point it to new_mthd
# The next time org_mthd is called new_methd will be executed
def add_chain org_mthd, new_mthd, org_alias
    self.class.class_eval do
      (alias_method org_alias, org_mthd) unless method_defined? org_alias
      alias_method org_mthd, new_mthd
    end
  end

  # Extremly evil code ahead!
  def decorate method, decorator
    # Create a chain counter if it doesn't exist
    @chain_counter ||= 0
    # Use the chain counter as a method id
    i = (@chain_counter += 1)

    # Create a new method which will dispatch the call to both                                                                                                    # the original and the decorator method
    self.class.class_eval
      def chain_dispatcher#{i} *params
        #{decorator} *params
        chain_original#{i} *params                                                                                                                                  end
    EOM

    # Once the method was created, add chain
    eval "add_chain method, :chain_dispatcher#{i}, :chain_original#{i}"
  end
end

class Foo
  include MethodDecorator
  def foo; print "Hello "; end
  def bar; print "worldn"; end
  def initialize; decorate :bar, :foo; end
end

Foo.new.bar

Ahora si, tengo que buscar ya un plugin para código.

Edit: Agregado el plugin para código!

Lyx

Continuando el post sobre aplicaciones necesarias para un nuevo sistema, un review que escribí hace tiempo sobre Lyx, un frontend para LaTeX:

(Tip: hay una versión para Windows)

// TODO

Add a CODE tag

apt-get new computer

Siempre me olvido cuales son los paquetes copados para instalar en un nuevo sistema así que voy a copiarlo acá. Después pongo links a cada aplicación.

self.start

Superado el primer post casi obligatorio, ¿de que se trata todo esto?

Planeo volcar acá todo tipo de locuras que se me ocurran, muchas de las cuales estarán dedicadas a la informática. Prometo mantener al mínimo los meta-posts.

El contenido estará mayormente en español pero como las estadísticas muestran hits de otros lados (yo tampoco me explico cómo) algunas cosas irán traducidas.

With obliged frist post out of the way, what's all this about?

I'm planning to dump here all kind of crazy ideas I can think of, many of which will be about computing. I promise to keep meta-posts to a bare minimum.

The content will be mainly in Spanish but as the statistics show hits from some other places (I have no idea why neither) some things will be translated.

Bonus points para quien adivine de donde saqué la imagen.
