feat: toggle intergrations

[sand4rt]

Describe the problem

Would it be possible for NNP to automatically close an integration when another one is opened on the same left/right position?

Describe the solution

1. Enable NNP
2. Open Neotree (or another any other integration)
3. Open Undotree (or another any other integration)
4. Neotree should be closed en Undotree should take the space of Neotree

Hey, I guess it could but that's a bit out of scope of the plugin, I assume a simple autocmd would be enough to do it, yet nnp should still behave correctly

I thought it didn't make much sense to have two integrations open on the same side.

Thanks for the pointer! I'll give it a try with an autocmd. Feel free to close if this does not belong in NNP.

Its quite a bit of code to implement in user land, but this is what i have now. If anyone has suggestions for improvements, please let me know:

vim.api.nvim_create_autocmd("FileType", {
    pattern = {
        "neo-tree",
        "undotree",
        "neotest-summary",
        "dbui",
        -- "dapui_*" TODO: turn when this is resolved: https://github.com/rcarriga/nvim-dap-ui/issues/329
        "dapui_scopes",
    },
    callback = function()
         if vim.bo.filetype == "neo-tree" then
            pcall(vim.cmd.UndotreeHide)
            pcall(vim.cmd.DBUIClose)
        elseif vim.bo.filetype == "undotree" then
            vim.cmd("Neotree close")
            pcall(vim.cmd.DBUIClose)
            -- fixes undotree width: https://github.com/mbbill/undotree/issues/143
            vim.api.nvim_win_set_width(vim.api.nvim_get_current_win(), vim.g.undotree_SplitWidth)
        elseif vim.bo.filetype == "dbui" then
            vim.cmd("Neotree close")
            pcall(vim.cmd.UndotreeHide)
            -- fixes dap ui width
            vim.api.nvim_win_set_width(vim.api.nvim_get_current_win(), vim.g.db_ui_winwidth)
        elseif string.find(vim.bo.filetype, "^dapui") then
            pcall(function()
                vim.cmd("Neotest summary close")
            end)
        elseif vim.bo.filetype == "neotest-summary" then
            -- TODO: this only works once because of https://github.com/rcarriga/nvim-dap-ui/issues/397
            require("dapui").close()
        end
    end,
})
