I've discovered of a few variants on my second solution (the
one using ^V) since last night. Below, I will show the characters as
one types them rather than as they eventually appear. First variant:
:unab yes^V!<CR>
Explanation: the unab command will take as its argument either the
abbreviation or its expansion. (Side comment: Suppose you do
:ab a x|ab b x|ab c x. Then any of the commands unab a, unab b, unab c,
will be "transformed" into unab x, and this will only undo the last of
these 3 abbreviations. You can undo all 3 with unab x|unab x|unab x.
If you want to specifically unabbreviate b, you can do :unab ^Vb.)
Second variant
:ab yes^V! oui
:unab yes!<CR>
Explanation: If you do two "chained" abbreviations, such as
ab x y and then ab y z, the second cancels the first. I can't
imagine why. If you really want to have both, you can do them
in reverse order: ab y z then ab x y^V|
Third variant:
:ab yes^V oui
:unab yes|unab yes
I leave you to discover why you have to unab yes twice. You could
equally well use "oui" in its place, for the reason mentioned under
the first variant.
Further comment: the setting :se noremap doesn't seem to have
any effect on this nonsense.
Do these solutions work for other people as they do for me?
Any other comments?
