The 'k' was fixing downward movement of $ command. After replacing with
normal! $, it works without that fix.
`$' does not move downward on its own. I don't see why it should move downward
(unless you kill that condition: in this case it will move because 0-1==-1 and
`-' moves, but upward).
It does move downward. 3$ moves 2 lines downward, etc.
2. :h map-<expr>:
nnoremap $ "<Bar>$".((v:count>1)?(((v:count-1).'h'):(''))
That doesn't work for me, using vim 7.3 (even after adding the ')').
However, I prefer the function version because it's more readable.
Oops, I forgot to pull fixes to the message after testing:
nnoremap<expr> $ "<Bar>$".((v:count>1)?((v:count-1).'h'):(''))
Thanks, that works and good to know. I think I still prefer function
version for readability.
I see, but<c-u> seems like a pretty bad kludge. I remember using it at
least a couple of times before, and I still did not remember it because
it's pretty counter-intuitive. I think it would be better if there was
an arg to *map to turn it off, like<no-prepend-range>, because users
would look into *map arguments help for explanation of this behaviour.
It is not related to :*map at all, it is property of `:'. By the way, you saw
`<Bar>' above? It is for the same job here: drop count. Another possibility is
<C-\><C-n>: in this case {count} is ignored.
Ok, I see.. but why does map or function have to do anything with that,
they already get v:count and v:linenumber1 etc (IIRC), why isn't it up
to them to choose how to use or not use them?
Because v:count is reset each time normal-mode command is executed. Guess
why in
> exe "normal \<End>"
command is called *normal*?
That doesn't seem reasonable, why should Vim assume the count applies to
the first (of possibly dozens) normal command in a function?
I don't said it is *applied*. I said it is *reset* when normal-mode command is
executed. `normal' does execute the normal-mode command as clearly stated by its
name.
Either reset or applied, I don't see the logic in having that happen
with the first normal command in a function.
Anyway, thanks a ton for your help and here's what I ended up with if
anyone wants to use this too:
func! EndOfLine()
" Go to Nth char before end of line
normal! $
if v:count | exe "normal ".v:count."h" | endif
endfu
nnoremap $ :<c-u>call EndOfLine()<cr>
This won't work for {count}$, see above.
?? It does work for me in Vim 7.3. For both $ and {count}$ .
