Add option to list kill ring entries

[paulmiu]

I couldn't find any command to obtain (or variable that holds) the entries of the killring feature (except the two bind input functions yank and yank-pop which don't list all entries).

Or is there another option to get all entries from the kill ring?

There currently is not.

See also #4028, which could use it.

The obvious question is what this should look like:

• A command that prints the entries?
• A variable that contains them, like $history?

There seems to be $fish_killring

Yup, forgot to close this one (never really sure when exactly Github does that for you).

While at it: Is it somehow possible to remove an entry from the killring? yank-pop does not seem to do anything for me (also no rotating which is mentioned in the docs) and set --erase does not work for that read-only variable

not yet, probably we should support set --erase

yank-pop does not seem to do anything for me (also no rotating which is mentioned in the docs)

it only rotates what is inserted to the commandline after C-y (the GNU Emacs tutorial explains how this kind of killring works)

I would also be fine with an extra function. My use case is a push-line like functionality with a stack (such that multiple commands can be stored and popped one after another) for which I wanted to use the built in killring. For now I will try to implement it using a normal list.

Oh that makes a lot more sense now. I did not knew the concept was based on Emacs - that also explains the terminology which was rather confusing to me as I normally associate yanking with copy/cut.

Should I create an issue for that (i.e. some way to remove entries from the killring)?
