It is working with the exact (very simple) example that I've written previously.
But it is not working at all with a slightly more complicated real example like that :

	@articles = @article.category_id.present? ? Article.where('category_id = ?', @article.category_id) : []

I'd like to obtain this :

	variable = Article.where('category_id = ?', @article.category_id)
	@articles = @article.category_id.present? ? variable : []



I guess your solution doesn't work in this example because of the whitespaces, …


In Vim, it seems that it can be done with a prompt of the desired variable name, then replacing the selected text with it, and finally inserting the assignment on a new line above.

Does this seems feasible in TextMate?

I should have stated that I'm using TextMate Version 1.5.11 (1634)

I'm not a big fan of alpha software for my day to day use ;-)



Thank you so much for your help, it's really appreciated.
