Aptana Studio 3 Snippet Around Selection - ruby-on-rails

Question

So I have recently switched from Dreamweaver to Aptana Studio 3 and I have been playing around with the whole custom snippet feature. For the life of me though I cannot figure out how to take a selection/highlighted text and wrap it with my own custom code and/or text. I have looked around the internet for three days now and cannot find anything regarding snippets. I have found some things using commands and key combinations, but I am wanting to create and use a snippet and trying to modify what I have found is not producing good fruit.
I have been able to create my own category and some basic snippets that insert straight text, but nothing that uses a selection.
I have absolutely NO experience with Ruby so forgive me if what follows is completely atrocious. I have more experience with PHP, HTML, Javascript, Java, etc. Here is what I have so far.
snippet "Selection Test" do |snip|
snip.trigger = "my_code"
snip.input = :selection
selection = ENV['TM_SELECTED_TEXT'] || ''
snip.expansion = "<test>$selection</test>\n"
snip.category = "My Snippets"
end

Answer 1

I haven't done much with custom Snippets, but if it helps, there is an example in the HTML bundle of a snippet that surrounds the selected text with <p></p> tags when you do Ctrl + Shift + W. You can see the code for it in snippets.rb in the HTML bundle:
with_defaults :scope => 'text.html - source', :input => :none, :output => :insert_as_snippet do |bundle|
command t(:wrap_selection_in_tag_pair) do |cmd|
cmd.key_binding = "CONTROL+SHIFT+W"
cmd.input = :selection
cmd.invoke do |context|
selection = ENV['TM_SELECTED_TEXT'] || ''
if selection.length > 0
"<${1:p}>${2:#{selection.gsub('/', '\/')}}</${1:p}>"
else
"<${1:p}>$0</${1:p}>"
end
end
end
end
I fiddled around with putting it into the PHP bundle for a few minutes under CTRL + Shift + P and got it working in HTML files, which was not my goal... but was progress. I may play around with it some more later, but in the meantime, maybe you know enough after all of your research to get something put together. I would be interested to see your results if you get this figured out.
