Vipe is a Vim command pipe editor which allows you to run a text editor in the middle of a unix pipeline and edit the data that is being piped between programs.
It's something considered to be on topic?
It's a stand-alone program, allows you to run a text editor in the middle of a unix pipeline and as far as I know it's compatible with original vi operations. Vipe is part of moreutils
package.
