line-mode ex is scriptable. The TUI that can be started using
':visual' (hence its commonly known name 'vi') isn't. ex's ancestor
ed is scriptable as well. I sometimes use the latter for shell script
controlled in-place editing of files to avoid unnecessary security
issues resulting from the creation and deletion of temporary files
(that is one of the largest source of harmful security holes known to
authors of shell scripts). It is a pity that many people only know
sed (wich is nothing but a stripped-down version of ed only being
capable to handle streams) because they are doomed to introduce such
problems.
