Subject: [PATCH 1/3] direnv.nvim: complete plugin overhaul

I should have worked more with atomic commits and less with whatever the
hell this is supposed to be, but hindsight is 20/20. tl;dr is that this
refactor improves the plugin with better UX, slightly better
performance, and better compatibility with Neovim 0.10, which I have
overlooked last time. Changes are, from memory, as follows:

- Caching system to prevent excessive direnv status checks
- Statusline integration to show direnv status in real-time
- Proper async handling for all operations
- Added (subpar) .envrc file editor with creation prompt
- Added autocmd hooks for other plugins (User `DirenvLoaded`, fixes #5)
- Better, comprehensive notification system with proper scheduling
- Intuitive handling of allowed/pending/blocked states
- Added command to check direnv status
- Improved contextual commands and keyboard mappings (despite "best"
  practices)

For those who have direnv.nvim already set up (despite the repo being
archived for months), I tried to retain full backwards compat. New
functionality and error fixes were built on top.

 # direnv.nvim
 
 Dead simple Neovim plugin to add automatic Direnv loading, inspired by
-`direnv.vim` and written in Lua.
+`direnv.vim` and written in Lua for better performance and maintainability.
+
+## ✨ Features
+
+- Seamless integration with direnv for managing project environment variables
+  - Automatic detection of `.envrc` files in your workspace
+  - Proper handling of allowed, pending, and denied states
+- Built-in `.envrc` editor with file creation wizard
+- Statusline component showing real-time direnv status
+- Event hooks for integration with other plugins
+- Comprehensive API for extending functionality
+
+### 📓 TODO
+
+There are things direnv.nvim can _not_ yet do. Mainly, we would like to
+integrate Treesitter for **syntax highlighting** similar to direnv.vim.
+Unfortunately there isn't a TS grammar for Direnv, but we can port syntax.vim
+from direnv.vim.
+
+Additionally, it might be worth adding an option to allow direnv on, e.g.,
+VimEnter if the user has configured to do so.
 
 ## 📦 Installation
 
 Install `direnv.nvim` with your favorite plugin manager, or clone it manually.
 You will need to call the setup function to load the plugin.
 
+### Prerequisites
+
+- Neovim 0.8.0 or higher
+- [direnv](https://direnv.net/) installed and available in your PATH
+
+### Using lazy.nvim
+
+```lua
+{
+  "NotAShelf/direnv.nvim",
+  config = function()
+    require("direnv").setup({})
+  end,
+}
+```
+
 ## 🚀 Usage
 
-direnv.nvim will automatically call `direnv allow` in your current directory if
-`direnv` is available in your PATH, and you have auto-loading enabled.
+direnv.nvim will manage your .envrc files in Neovim by providing commands to
+allow, deny, reload and edit them. When auto-loading is enabled, the plugin will
+automatically detect and prompt for allowing `.envrc` files in your current
+directory.
 
-## 🔧 Configuration
+### Commands
+
+- `:Direnv allow` - Allow the current directory's .envrc file
+- `:Direnv deny` - Deny the current directory's .envrc file
+- `:Direnv reload` - Reload direnv for the current directory
+- `:Direnv edit` - Edit the `.envrc` file (creates one if it doesn't exist)
+- `:Direnv status` - Show the current direnv status
+
+### Configuration
 
 You can pass your config table into the `setup()` function or `opts` if you use
 `lazy.nvim`.
 
 ### Options
 
-- `bin` (optional, type: string): the path to the Direnv binary. May be an
-  absolute path, or just `direnv` if it's available in your PATH. - Default:
-  `direnv`
-- `autoload_direnv` (optional, type: boolean): whether to call `direnv allow`
-  when you enter a directory that contains an `.envrc`. - Default: `false`
-- `keybindings` (optional, type: table of strings): the table of keybindings to
-  use.
-  - Default:
-    `{allow = "<Leader>da", deny = "<Leader>dd", reload = "<Leader>dr"}`
-
-#### Example:
-
 ```lua
 require("direnv").setup({
-   autoload_direnv = true,
+  -- Path to the direnv executable
+  bin = "direnv",
+
+  -- Whether to automatically load direnv when entering a directory with .envrc
+  autoload_direnv = false,
+
+  -- Statusline integration
+  statusline = {
+    -- Enable statusline component
+    enabled = false,
+    -- Icon to display in statusline
+    icon = "󱚟",
+  },
+
+  -- Keyboard mappings
+  keybindings = {
+    allow = "<Leader>da",
+    deny = "<Leader>dd",
+    reload = "<Leader>dr",
+    edit = "<Leader>de",
+  },
+
+  -- Notification settings
+  notifications = {
+    -- Log level (vim.log.levels.INFO, ERROR, etc.)
+    level = vim.log.levels.INFO,
+    -- Don't show notifications during autoload
+    silent_autoload = true,
+  },
 })
 ```
+
+### Statusline Integration
+
+You can add direnv status to your statusline by using the provided function:
+
+```lua
+-- For lualine
+require('lualine').setup({
+  sections = {
+    lualine_x = {
+      function()
+        return require('direnv').statusline()
+      end,
+      'encoding',
+      'fileformat',
+      'filetype',
+    }
+  }
+})
+
+-- For a Neovim-native statusline without plugins
+vim.o.statusline = '%{%v:lua.require("direnv").statusline()%} ...'
+```
+
+The statusline function will show:
+
+- Nothing when disabled or no .envrc is found
+- "active" when the .envrc is allowed
+- "pending" when the .envrc needs approval
+- "blocked" when the .envrc is explicitly denied
+
+## 🔍 API Reference
+
+**Public Functions**
+
+- `direnv.setup(config)` - Initialize the plugin with optional configuration
+- `direnv.allow_direnv()` - Allow the current directory's `.envrc` file
+- `direnv.deny_direnv()` - Deny the current directory's `.envrc` file
+- `direnv.check_direnv()` - Check and reload direnv for the current directory
+- `direnv.edit_envrc()` - Edit the `.envrc` file
+- `direnv.statusline()` - Get a string for statusline integration
+
+### Example
+
+```lua
+local direnv = require("direnv")
+
+direnv.setup({
+  autoload_direnv = true,
+  statusline = {
+    enabled = true,
+  },
+  keybindings = {
+    allow = "<Leader>ea", -- Custom keybinding example
+  },
+})
+
+-- You can also call functions directly
+vim.keymap.set('n', '<Leader>er', function()
+  direnv.check_direnv()
+end, { desc = "Reload direnv" })
+```
+
+### Events
+
+The plugin triggers a User autocmd event that you can hook into:
+
+```lua
+vim.api.nvim_create_autocmd("User", {
+  pattern = "DirenvLoaded",
+  callback = function()
+    -- Code to run after direnv environment is loaded
+    print("Direnv environment loaded!")
+  end,
+})
+```
