Git and Sessions

Git Integration

Gitsigns (Signs in the Gutter)

{
  "lewis6991/gitsigns.nvim",
  config = function()
    require("gitsigns").setup({
      signs = {
        add          = { text = "│" },
        change       = { text = "│" },
        delete       = { text = "_" },
        topdelete    = { text = "‾" },
        changedelete = { text = "~" },
      },
      on_attach = function(bufnr)
        local gs = package.loaded.gitsigns
        local opts = { buffer = bufnr }

        vim.keymap.set("n", "]h", gs.next_hunk, opts)
        vim.keymap.set("n", "[h", gs.prev_hunk, opts)
        vim.keymap.set("n", "<leader>hp", gs.preview_hunk, opts)
        vim.keymap.set("n", "<leader>hb", gs.blame_line, opts)
        vim.keymap.set("n", "<leader>hs", gs.stage_hunk, opts)
        vim.keymap.set("n", "<leader>hr", gs.reset_hunk, opts)
      end,
    })
  end,
}

Fugitive (Full Git Interface)

{
  "tpope/vim-fugitive",
  keys = {
    { "<leader>gs", "<cmd>Git<cr>", desc = "Git status" },
  },
}

Fugitive provides :Git (or :G), which opens a git status window. From there you can:

Stage files with - (in the status window)
Commit with cc
Diff with dd
Push with :Git push

Sessions and Persistence

Vim Sessions

Sessions save your entire editing state: open files, window layout, cursor positions.

:mksession ~/mysession.vim    " Save session
:source ~/mysession.vim       " Restore session
nvim -S ~/mysession.vim       " Restore session on startup

Persisted.nvim (Automatic Sessions)

{
  "olimorris/persisted.nvim",
  config = function()
    require("persisted").setup({
      save_dir = vim.fn.expand(vim.fn.stdpath("data") .. "/sessions/"),
      autoload = true,  -- Auto-load session on startup
    })
  end,
}

Undo Persistence

vim.opt.undofile = true  -- in init.lua

This saves your undo history across sessions. You can undo changes even after closing and reopening a file.
