These look really good. I started down the same track a while ago but ended but being to busy doing other things as usual. I managed 4 video's which can be found here. Hope you can keep it going for longer than I did! Glen

Jordan, I definitely am not a Ruby master and Im doing the tips in about 10 minutes or less with no planning. So, definitely there is a good chance the ruby syntax will be wrong. FWIW i think your assessment of the code is correct.

My main argument is why are you programming from the console? It should be in frequent enough that your editor habits shouldn’t be too cumbersome. Though I admit when I am in console I swear a lot more.

I learned the Control-L shortcut to type a hashrocket (=>), then switched back to the manual way when I found myself trying (and failing) to type Control-L in the Console. Choose your habituations wisely.

I’m really thrown by your last Hash example. What exactly is:

Hash.new {|format.xml, xml| format.xml[xml] = @post}

doing?

From what I understand, Hash.new {|hash, key| …} allows you to create a Hash with a custom default value. But then having format.xml as a block parameter results in format.xml getting set to the hash you created..? It seems to be equivalent to:

h = Hash.new do |hash, key|
format.xml = h
format.xml[key] = @post
end

Is that right? What does that end up doing exactly?

Great quick tutorial. I’ve been using TextMate for long time now but I haven’t taken the time to learn all the magic it can do. Keep it coming!

Here is a shortcut that saves me a lot time:

Patrick,

I plan to do all the tips as screencasts. The goal is to keep them under 2 minutes. Bite size. I also plan on doing BASH (shell) tips of the day as well. As always I have even a bigger master plan than that, but figured we would start here.
