I've used vi for decades, and am now practicing using vim, expecting
eventually to switch to it entirely.
I have a number of questions, but I'll start with the one that
troubles me most. Something I have long done in vi is to type
a bottom-line command into the file I am editing, yank it to a named buffer
(e.g., using the keystrokes "ayy) and execute that buffer (using
:@a^M). This allows me to edit complicated commands till they
work right, and to keep commands that I will use many times as I
work in a file. (I have
in my .exrc file a mapping that reduces this yank-and-execute to a
single keystroke; but that isn't relevant to my question.)
I find that in vim, I need a lot more ^Vs than in vi. This
means, on the one hand, that when I have some command-line in a file
that I expect to use this way, I now need to keep it in two
versions, one for vi and one for vim. Also, the requirement of the
extra ^Vs seems inelegant: evidently various special characters
that are interpreted once when the named buffer is executed in vi
are interpreted twice when its is executed in vim -- but why?
As an example, a command of the form
map =f :w^V|e foo^M
(mapping the keystroke-sequence =f to write the current file
and go to the file foo) works this way in vi, but has to have the form
map =f :w^V^V|e foo^V^M
in vim. (Here in both commands, ^V is gotten by typing ^V^V,
and ^M is gotten by typing ^V^M; so typing the first version
involves typing three ^Vs, and the second, seven.) To be
exact: the first version does work in vim if one actually
types it into the bottom line (with the indicated extra ^Vs);
but the latter is required in an executed named buffer.
Any explanation? Anything I can set to fix this? ("compatible" doesn't seem to do it.) Any hope that it will be fixed in a future release? (The system I am on uses version 7.0.)
(I should confess that I'm not a programmer; just a user who has become proficient in vi.)
