What do you mean by "command"? Many (most?) of BBEdit's actions
require user input before they can be completed.
One possible answer is: what happens when you type "." in Vim, which
I believe really does mean "repeat last command," so you can play
around with it for a minute or two to see the effects. If the last
thing was to delete the word the cursor is on, it does that. If it was
to delete a line, it does that. If it was to insert the phrase "lorem
ipsum blah blah blah," it does that. If it was to append the phrase
"lorem ipsum blah blah blah" to the end of the current line, it does
that.
This makes sense in vi where it has two different modes.
What’s the last thing I did? Type this word? This line? This
paragraph? This entire reply? where is the break between the current
thing I did and the last thing I did? In an editor without a specific
insert state and a specific command state it is impossible to
delineate what the ‘last’ thing was and the programmers would have to
make some capricious decisions as to where to stop one ‘thing’ and
start the next ‘thing’.
Maybe when I stop typing for more than 5 seconds, that’s the ‘end’ of
something. Maybe it’s when I move the insertion point. How about if I
type something and then backspace and type over it. Is that a new
command to repeat, or not?
Or is it just a “whatever I last did from the menu, do that exact
thing again”? While that might be useful in some limited cases, I bet
what each person means by ‘do the last command again’ is pretty
different form the next person.
The breakup into 'blocks of actions' has already been defined for the
undo command. For menu-actions this is clear, for typing it seems to me
that it mostly works. That doesn't mean that a repeater is needed or a
good idea, the problem does not exist in the breakup of actions.
