Create temporary playground files effortlessly. Find them later without worrying about filenames or locations

  • With other nvim's goodies.
    • with treesitter to have syntax highlighting
    • with lsp and cmp to have auto-cmp, auto-format and other lsp goodies
    • with michaelb/sniprun or metakirby5/codi.vim to run scratch file

Scratch Intro


using your favorate plugin manager, for example lazy.nvim

  event = "VeryLazy",


No need to config at the very begining, just install and explore the commands start with Scratch.

The way to config this plugin is a little difference(simpler) with other nvim plugin.

You can use ScratchEditConfig to edit the config once some new type popup your mind and the config will take effect immediately

Here's default config after you inited the plugin

NOTE: you can't have comment in your config, since only plain json supported right now

  "filetypes": ["xml", "go", "lua", "js", "py", "sh"], // you can simply put filetype here
  "window_cmd": "edit", // 'vsplit' | 'split' | 'edit' | 'tabedit' | 'rightbelow vsplit'. Can use rightbelow or topleft etc. as modifier
  "scratch_file_dir": "/you_home_path/.cache/nvim/scratch.nvim",
  "filetype_details": {
    "go": {
      // or, you can have more control here
      "filename": "main", // the filename of the scratch file in the new directory
      "cursor": {
        "location": [4, 2], // default location of cursor in the scratch file
        "insert_mode": true // default mode
      "requireDir": true, // true, if each scratch file requires a new directory
      "content": ["package main", "", "func main() {", "  ", "}"] // default content in the scratch file
    "yaml": {}, // for same filetype. you can have different postfix
    "k8s.yaml": {
      "subdir": "learn-k8s" // and put this type into a specific subdir
    "json": {}, // empty object is fine
    "": {
      // create `gp.nvim` chat file
      "cursor": {
        "location": [12, 2],
        "insert_mode": true
      "content": [
        "# topic: ?",
        "- model: {\"top_p\":1,\"temperature\":0.7,\"model\":\"gpt-3.5-turbo-16k\"}",
        "- file: placeholder",
        "- role: You are a general AI assistant.",
        "Write your queries after 🗨:. Run :GpChatRespond to generate response.",
  "localKeys": [
    // local keymapping for specific type of file
      "filenameContains": ["gp"],
      "LocalKeys": [
          "cmd": "<CMD>GpChatRespond<CR>",
          "key": "<C-k>k",
          "modes": ["n", "i", "v"]

  • This is triggered automaticlly at the first time you try to use Scrach's commands, and can be manually called to change the configuration file path, and this allows you:
    • Put your configuration anywhere you want and can be tracked along with your other configuration with git
    • Have multiple configuration, and switch the configuration by change the configuration filepath with this command

Check current Configuration
