wrapper functions which can be used to define count prefixed, dot repeatable keymaps

[tummetott]

The added wrapper functions can be used in keymaps like following:

vim.keymap.set(
    'n',
    '[s',
    function ()
        vim.go.operatorfunc = "v:lua.require'iswap'.iswap_node_with_left"
        return 'g@l'
    end,
    { desc = 'Swap with [count] left node', expr = true }
)

vim.keymap.set(
    'n',
    ']s',
    function ()
        vim.go.operatorfunc = "v:lua.require'iswap'.iswap_node_with_right"
        return 'g@l'
    end,
    { desc = 'Swap with [count] right node', expr = true }
)

The resulting keymaps are dot repeatable and can be prefixed with [count].
Examples: 2[s, ]s

Is there a way to make setting up a dot-repeatable keymap easier than this? It seems like there still is a bit of boilerplate for the user when configuring this way.

I'm only aware of two methods getting dot repetition. One is using operatorfunc as I did, the other is using a third party plugin like vim-repeat. I could never understand the code of vim-repeat since I'm not familiar with vimscript. I've noticed that you added vim-repeat support in your plugin already. However I don't like having an extra plugin for this.

See this link

The implemented version with vim-repeat is a little broken too: When I swap a node with :ISwapWithLeft and then press ., then I get promped to pick a node to swap with. I would expect that the :ISwapWithLeft command is re-executed, but in reality the :ISwapWith command is executed.

understood, thanks! Can I put the operatorfunc bit into my plugin as opposed to the user putting it into their configuration.

[tummetott]

Yes that would be possible. I can make a PR for this next week.

thanks! i would appreciate that a lot. i'm not super familiar with operatorfunc
