TL;DR

More on Romeo’s slicing support.

In Romeo - slice we took a look at Romeo’s slicing capabilities, i.e. to extract some selected pieces out of a lot.

We saw that it has two capabilities:

• loading slice definitions from a file, to be used over and over, and
• an interactive mode to choose data directly from the first record of a series (or the only one present, if the input data is a hash).

It was just too natural to use the same interactive mode that we already saw to generate the definitions that we can reuse over and over, right?

Enter romeo slice-build. It has pretty much the same interface, but instead of printing out slices out the input data, it provides us with the definitions that can then be reused later.

Let’s see it in action:

I hope this can be helpful, stay safe!
