Blink on nixos using vim.pack

[rohrsben]

Hey all! Got a rudimentary version of this working. Figuring I'd share and see if anyone had some tips or improvements. Edit: this is in nvim/plugin/blink.cmp

local function start_blink()
    require('blink.cmp').setup {
        -- snip
    }
end

vim.api.nvim_create_autocmd('PackChanged', {
    once = true,
    callback = function (info)
        if info.data.spec.name == 'blink.cmp' then
            local result
            if info.data.kind ~= 'deleted' then
                vim.notify('Building Blink')

                result = vim.system(
                    {'nix', 'run', '.#build-plugin'},
                    { cwd = info.data.path }
                ):wait()
            end

            if info.data.kind == 'installed' then
                if result.code == 0 then
                    vim.api.nvim_create_autocmd('UIEnter', {
                        once = true,
                        callback = function ()
                            vim.notify('Blink build successful. Starting')
                            start_blink()
                        end
                    })
                else
                    vim.api.nvim_create_autocmd('UIEnter', {
                        once = true,
                        callback = function ()
                            vim.notify('Blink build failed. Code: ' .. result.code)
                        end
                    })
                end
            elseif info.data.kind == 'updated' then
                if result.code == 0 then
                    vim.notify('Blink build successful. Starting')
                    start_blink()
                else
                    vim.notify('Blink build failed. Code: ' .. result.code)
                end
            end

            vim.g.dont_start_blink = true
        end
    end
})

vim.pack.add({'https://github.com/Saghen/blink.cmp'})

if vim.g.dont_start_blink == nil then start_blink() end

The result autocmd's are on UIEnter so that mini.notify properly picks them up. I threw once onto all of them since they were running twice for some reason, and couldn't be bothered to figure out why. Currently this hard blocks the UI until blink is done building, but it was basically like that in lazy anyways, and it's not like I'll be writing much code without it. Could be improved, though. I'm not actually sure how useful providing the result.code is, as I haven't had to see that branch yet.
