The first three lines are dedicated to collecting the inputs needed to make that fourth line successful. strftime(format) end We don’t always go to the trouble of distinguishing the “input collection” phase of a method from the “work” phase. But whether we separate it out into a distinct stanza or not, taking a little time to think about what inputs a method relies on can have a disproportionately large impact on the style, clarity, and robustness of the code that follows. From Roles to Objects To explain why this is, we need to go back to what we discussed in the previous chapter.
To_str # ... end Listing 27: Conditionally calling #to_path Of all the strategies for checking and converting inputs we’ve looked at, this one is the most flexible. We can pass String, Pathname, or any other object which defines a conversion to a path-type String with the #to_path method. But other objects passed in by mistake, such as nil or a Hash, will be rejected early. This use of #respond_to? is different from most type-checking in a subtle but important way. ”. ” as such, it strikes a useful balance.
You may reasonably wonder if this level of paranoia is really called for in most methods; and the answer is “no”. Programming defensively in every method is redundant, wasteful of programmer resources, and the resulting code induces maintenance headaches. Most of the techniques found in this section are best suited to the borders of your code. Like customs checkpoints at national boundaries, they serve to ensure that objects passing into code you control have the right “paperwork”—the interfaces needed to play the roles expected of them.
