I don't understand. I never meant to suggest that you try to
extract some code from that script or understand its internal
workings; I meant that you should use it as-is.

For example, with vis.vim installed and given the line

The quick brown fox jumped over the lazy dogs.

move the cursor to the f in fox and type

v2e:B !rev

and Enter. The result will be the line below, where the string
"fox jumped" was filtered by the external program rev and replaced
by the reversed string "depmuj xof ". (I don't know where the
extra two spaces came from, but that's not the point here.)

The quick brown depmuj xof over the lazy dogs.

That _is_ what vis.vim provides: a way to execute any Vim ex
command, including piping, on a selected region of text.

Am I missing something?
