The rendering of this post is all broken. It would be nice, if you could make it readable again.

Love it Larry – extremely useful and informative :) Nice to see this on the Cucumber docs wiki now too.

For more dry fun with cucumber models take a look at Ian White's pickle plugin, which lets you write steps like

Given a user exists with name: "Frank"
And I go to the user's page
Then I should see "name: Frank"

without writing any steps: it fits in with machinist, factorygirl, or just active record.

It's an ongoing project, but it works, and I find it very useful in speeding up feature writing.

Cucumber might not have your situation built in, but Transform's are very flexible! I think I understand what you need better now, check out this implementation of your TokenTransform: http://gist.github.com/191691

Is there a way to transform table data coming in. I'm working on some practice features for Conway's Game of Life (http://github.com/coreyhaines/practice_game_of_li... and I'd like to be able to use a transform to capture the tables.

It looks like pickle has the same idea with #{capture_model} and #{capture_fields}, but it doesn't seem to allow us to write our own "token transforms" either.

Yup, the Transform regex just has to match a capture group, not have identical text. That means groups in step defs that don't match anything get checked against every Transform, and a group that matches short circuits checking the rest.

Ok, so from from you're saying, it seems that the regular expression defined for a Transform does not have to appear verbatim in the regular expression of the Given/Then/When. That was not clear from reading the original description. So, that means that every single captured group (anything in parens) is potentially checked against every defined Transform. Is that right?
