RFC: Repeat multiple actions, compatible with Meow

[ideasman42]

There is a project I've been developing to support repeat for modal-editing systems (not specifically meow).
See URL: https://codeberg.org/ideasman42/emacs-repeat-fu

Motivation

When I first tried meow, I found the lack of an equivalent to VIM's repeat hard to get used to, despite the ability to record/replay macros, I often found myself wanting to repeat an insertion or a "change" to a selected symbol.

Since then I've written my own modal editing system (Bray) but I still wanted an equivalent to VIM's repeat - which could group commands.

The package I'm working on now is called repeat-fu which can have different back-ends. I've written one for Meow as well as my own system.

The grouping can be tweaked which quite a lot of flexibility currently it works as follows:

• Numeric prefix (if any)
• Commands that create the selection (if any)
• Command that edits OR All commands in insert mode.
• Exit insert mode.

This means you can (for example).

• Select a word.
• Extend numeric (N times).
• Change.
• Insert new text.
• Escape.

You can them move the cursor to a new location and repeat the commands.
Furthermore, repeating is context sensitive.

• If you already have a selection, the selection action is skipped (the existing selection is used instead).
• If you're already in insert mode, only the insert mode actions are repeated.

Other details could change though, I have this working for Bray too and find it very convenient and use it many times a day.

From my initial testing it works really well, so I'm adding this to my config, thanks a lot!
