feat: Make it toggle to the last used repo on nvim open

[InfiniteRain]

Is there a way to make it open in the last repo use on opening nvim? Currently it defaults to root when I open nvim. If there's no way to change that then I can offer to implement it myself and make a PR.

Hey! Unfortunately this doesn't exist yet but I'm open to PRs :)

You can make this work with vim-prosession. This automatically tracks starts and opens your sessions.

However, this doesn't work out of the box. The SessionLoadPost autocmd will set the monorepo to the subfolder/subproject you're opening.

For me the following works. I've modified the change_monorepo method so that when it is called with a directory, it will find the git repository ancestor. This will probably not a one-size-fits-all solution, but it might help :-) This will also make sure when you open vim in one of the subproject folders, you will still get the proper monorepo.

I think it would be nice to have this mono_dir function configurable, just like with lspconfig.root_dir.

-- Modify change_monorepo so that it will always pick a git directory.
M.change_monorepo = function(path)
    local git_repo = vim.fn.finddir(".git/..", vim.fn.fnamemodify(path, ":p:h") .. ";")
    M.currentMonorepo = git_repo
    utils.load()
end

I've overridden the method like so, using Lazy as package manager (warning, hacky solution ;-)):

return {
  {
        "imNel/monorepo.nvim",
        config = function()
            local monorepo = require("monorepo")
            local utils = require("monorepo.utils")
            -- Modify change_monorepo so that it will always pick a git directory.
            monorepo.change_monorepo = function(path)
                local git_repo = vim.fn.finddir(".git/..", vim.fn.fnamemodify(path, ":p:h") .. ";")
                monorepo.currentMonorepo = git_repo
                utils.load()
            end
            monorepo.setup()
        end,
        -- Required to allow the change_monorepo method to be overwritten in time.
        lazy = false,
        dependencies = { "nvim-telescope/telescope.nvim", "nvim-lua/plenary.nvim"},
        keys = {
            { "<leader>m", function() require("telescope").extensions.monorepo.monorepo() end },
            { "<leader>n", function() require("monorepo").toggle_project() end },
        },
    }, {
        -- Open previous session
        "dhruvasagar/vim-prosession",
        lazy = false,
        dependencies = {
            "tpope/vim-obsession",
        }
    }
}

Hope this helps!
