This screenshot has no word wrapping.

You can wrap words by using scope.sh ("man ranger" and search for "scope").
A command like

    fmt -s -w "$width"

does word wrapping, so you can simply pipe the text through it.  If you
got the program "highlight", for example, then just replace the line

  highlight --out-format=ansi "$path" | head -n $maxln

with

  highlight --out-format=ansi "$path" | head -n $maxln | fmt -s -w "$width"
