dls for backup!

gistfile1.rb

#
# Backup of mysql, files, whatever...
#

# example 1
backup.start do
  new :mysql => {:host => '0.0.0.0', :user => 'root', :password => 'mypass'}
  new :mysql => {:host => '0.0.0.0', :user => 'root', :password => 'mypass'}
  new :archive => {:host => '0.0.0.0', :user => 'root', :password => 'mypass', :remote_file => ''}
end

# example 2
backup do

  mysql do

    server "my server name" do
      user "user_server"
      password "password"
      tables [:table01, :table02, :table03]
    end

  end

  files do

    server "my server name" do
      host "0.0.0.0"
      user "user_server"
      password "password"
      remote_path "/remote/path/file/to/backup"
      local_path "/local/path"
    end

  end

end

# example 3

backup :of => :mysql do

  server :linode,
    :host => '0.0.0.0',
    :user => 'root',
    :password => 'my_pass'

  server :locaweb,
    :host => '0.0.0.0',

Nice DSL. What's your idea?

Just thought of something:

backup :of => :mysql do

from :linode,
:host...
:user...

to :locaweb,
:host...
:user...

You could use multiple from() and to() too.

My idea is to create a new DLS for backup.

There are alternatives, but no watch 100% of what I need. So I thought of making my own =)

Thanks!

Keep it up. When you start the project (if it's opensource), pass on the repo address ;)

I would discard example 1 since it uses new which is a reserved word. Even if there was a way to override it, it would become too confuse for my tastes.

I think the example 2 is better. I like the idea of using methods instead of a hash (looks like the Rails 3 routing API).

It looks great, congrats Jésus!

Thanks Lucas!

Cássio,
I agree with you, the example 1 is a pretty ugly :( The idea of using methods makes the code more beautiful!

Hey, congrats for the idea! :]
I personally think that example 3 is the easiest read, and seems the least verbose.
Oh, and example 2 is really RSpec-like! Which is a good thing considering how many people are used to it's sintax.
Great work! I'm looking forward into watching your repo
