Question Kill-ring modify last entry.

Question Kill-ring modify last entry.

[Ergus]

Hi:

I have been reading the elisp documentation and it is unclear for me if
there is a "canonical" (lets say formal/supported/provided/save)
function to replace the last entry in the kill-ring with a new one (like
the append option).

I have been playing with `current-kill` or just making (pop kill-ring)
before killing again but maybe there is a better alternative?

Thanks in advance,
Ergus

kill-new with its REPLACE argument non-nil, I think.  Is this what you
are looking for?

kill-new has a 'replace' argument, so:

(kill-new "foo" t)

(unless Iʼve misunderstood what youʼre asking for)

Hi:

I have already seen kill-new. I was just preventing myself to reinvent
the wheel in case there were something else already there.

I was looking for something like `append-next-kill` that I could use for
`copy-region-as-kill` (or similar), but for replace instead of
appending and acting on regions instead of passing the string already
manipulated.

Ideally I thought that the higher level functions (kill-region,
copy-region-as-kill) somehow unified the lower level functions
(kill-append, kill-new). Maybe throw parameters.

But ok, thanks.

I know what to do now :)

append-next-kill just arranges the next kill to call kill-new with the
REPLACE argument non-nil, that's all.  There's no magic there.  the
easiest way to mimic what append-next-kill does in your commands is to
call kill-new with that argument non-nil.

You asked about the "canonical" way of doing this; that way is to call
kill-new.
