Splitting flac and ape files in Debian / Ubuntu
Post by Nico Brailovsky @ 2008-10-28 | Permalink | Leave a comment
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
Source: BROKENLINK
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.
Back online!

Ruby: Method chaining
Post by Nico Brailovsky @ 2008-10-16 | Permalink | Leave a comment
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:

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.
