What's it for? (Score:1)

by jplindstrom (594)

I've seen the command in the manual but have never really used it. It sounds clever, but it's not something I ever felt I whish I could use.

Can you give a few real-life (as in "actual") scenarios when it's useful to use narrow?

  I think I typically use narrow for restricting the range of a search-and-replace.
  Example: I'm working on an HTML document and I want to paste in some Perl code or something. I type <pre>, paste the code, and </pre>, and then I realize I need to turn the &'s in the Perl code into &'s. So I select the Perl code that I just pasted in, hit Narrow, use replace-string to change &'s to &, and then hit Widen.

    Yup, that's the most common use I have for it as well. In fact if you're feeling really inspired a replace-regexp-narrowed (or maybe replace-regexp-region) that did just that (narrowed, replace-regexp, widened) could be useful.
