Dot repeatable

[tummetott]

It would be nice if commands like :ISwapNodeWithLeft could be made dot repeatable.

I managed to get dot repetition as following:

I created a file called wrapper.lua in my runtimepath

local M = {}

M.swap_left = function()
    require('iswap').iswap_node_with('left')
end

M.swap_right = function()
    require('iswap').iswap_node_with('right')
end

return M

Then i created keymaps in my plugin config:

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

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

The wrapper functions are needed since operatorfunc takes a function pointer and therefore, no arguments are allowed.

@mizlan maybe you can add the following functions for convenience?

require('iswap').iswap_with_left()
require('iswap').iswap_with_right()
require('iswap').iswap_node_with_left()
require('iswap').iswap_node_with_right()

Then users could define keymaps directly and does not have to define wrapers themself

Thank you for studying this issue @tummetott, I can finally repeat this operation.
Any news on the status of this PR ?

[tummetott]

Oh I totally forgot about this tbh. I'm quite busy atm but I'll look into this as soon as I have a little more time. Should not be hard to implement

[qleveque]

Actually it looks like you already implemented it, thank you for your work
@mizlan It would be really nice to merge this PR, would that be possible?

[tummetott]

No I didn't. @mizlan expressed his wish to include all the boilerplate code into the plugin. The PR I suggested needs some polishing
