Rubyglow

rubyglow is a ruby version of perl visualization software afterglow

Motivation

I like afterglow and I like security visualization but I don't like perl and I feel I want to mess with afterglow code and can't. So I decided to rewrite everything in ruby.

State and plans

At the moment every script from afterglow has been translated except for the main program in graph/.

At the moment I've tried to make a direct translation in order to understand the scripts and not change too much. The next step is to reshape everything in a more object oriented and flexible way. So much to factorize...

At the moment I'm thinking about what to do with the properties file. In the original afterglow this file can have perl code, so afterglow.rb will no longer be compatible.

That's why i'm left with two options:

• Do the same thing as original afterglow, using eval
• Create a DSL to describe the propierties

I guess the second option is more in the ruby way. That's why I've come up with this idea to configure afterglow:

Afterglow::properties do 
  cluster :event do |fields|
    regex_replace(".*?\\.(.*\\..*)") if (fields[1] !~ /\d+$/
  end
  size :all, 0.2 { |fields| fields[1] =~ /192.*/ }
  color :source, springgreen {|fields| fields[0] =~ /10\./ }
end

Commands will be:

color :all :source :target :event :edge :sourcetarget
size :all :source :target :event
threshold :all :source :event :target
shape :source :target :event
sum :source :target :event
label :source :target :event
url
cluster :source :target :event
maxnodesize
variable
exit
