### Setup nvim-projectconfig with Lua

Source: https://github.com/windwp/nvim-projectconfig/blob/master/README.md

Basic setup for nvim-projectconfig using Lua in your Neovim configuration.

```lua
require('nvim-projectconfig').setup()
```

--------------------------------

### Get Project Config Path by Extension

Source: https://context7.com/windwp/nvim-projectconfig/llms.txt

The `get_config_by_ext()` function retrieves the full path to the project configuration file based on the specified file extension (e.g., 'lua' or 'vim'). This is useful for scripting purposes or for checking the existence of a configuration file before attempting to load it.

```lua
-- Get the path to the Lua config for current project
local lua_config = require('nvim-projectconfig').get_config_by_ext('lua')
-- Returns: ~/.config/nvim/projects/myproject.lua

-- Get the path to the Vim config
local vim_config = require('nvim-projectconfig').get_config_by_ext('vim')
-- Returns: ~/.config/nvim/projects/myproject.vim

-- Check if a config file exists
local config_path = require('nvim-projectconfig').get_config_by_ext('lua')
if vim.fn.filereadable(config_path) == 1 then
  print('Project config exists at: ' .. config_path)
end
```

--------------------------------

### Install nvim-projectconfig with vim-plug

Source: https://github.com/windwp/nvim-projectconfig/blob/master/README.md

This snippet shows how to install the nvim-projectconfig plugin using the vim-plug package manager.

```vim
Plug 'windwp/nvim-projectconfig'
```

--------------------------------

### Configure Specific Project Paths and Loaders

Source: https://github.com/windwp/nvim-projectconfig/blob/master/README.md

This Lua snippet shows how to define specific project configurations, including custom paths and loading functions, for handling projects with the same name or custom loading logic.

```lua
require('nvim-projectconfig').setup({
  project_dir = "~/.config/projects-config/",
  project_config={
    {
      -- full path of your project or a lua regex string
        path = "projectconfig", 
        -- use a function or a path to config file 
        config = function ()
            print("abcde")
        end
    },
  },
  silent = false -- display message after load config file
})
```

--------------------------------

### Initialize nvim-projectconfig Plugin

Source: https://context7.com/windwp/nvim-projectconfig/llms.txt

Initializes the nvim-projectconfig plugin with optional configuration parameters. It sets the project directory, controls notification visibility, enables or disables auto-reloading on directory changes, and allows for custom project configurations to handle specific matching rules or provide custom config logic.

```lua
-- Basic setup with defaults
require('nvim-projectconfig').setup()

-- Advanced setup with all options
require('nvim-projectconfig').setup({
  -- Directory where project configs are stored (default: ~/.config/nvim/projects/)
  project_dir = "~/.config/nvim/projects/",

  -- Whether to show notification after loading config (default: true = silent)
  silent = false,

  -- Auto-reload config when directory changes (default: true)
  autocmd = true,

  -- Custom project configs for handling name conflicts or special cases
  project_config = {
    {
      -- Match by exact path or Lua pattern
      path = "/home/user/work/awesome-project",
      -- Config can be a file path
      config = "~/.config/nvim/projects/work-awesome.lua"
    },
    {
      -- Use Lua regex pattern for flexible matching
      path = "frontend%-app",
      -- Or config can be a function
      config = function()
        vim.opt.tabstop = 2
        vim.opt.shiftwidth = 2
        vim.g.my_project_type = "frontend"
      end
    },
  },
})
```

--------------------------------

### Customize Project Configuration Directory

Source: https://github.com/windwp/nvim-projectconfig/blob/master/README.md

This Lua snippet demonstrates how to change the default directory where project configurations are stored.

```lua
require('nvim-projectconfig').setup({
  project_dir = "~/.config/projects-config/"
})
```

--------------------------------

### Open Project Configuration File

Source: https://context7.com/windwp/nvim-projectconfig/llms.txt

The :EditProjectConfig command opens the project configuration file for the current directory. It prioritizes `.vim` configuration files if they exist, otherwise, it opens or creates the `.lua` configuration file. This command can be mapped to a keybinding for convenient access.

```lua
-- In Neovim command mode, open the project config for current directory
-- :EditProjectConfig

-- You can also map it to a keybinding in your init.lua
vim.keymap.set('n', '<leader>pc', '<cmd>EditProjectConfig<cr>', { desc = 'Edit project config' })

-- Example: If you're in /home/user/projects/myapp/
-- This will open ~/.config/nvim/projects/myapp.lua for editing
```

--------------------------------

### Enable Autocommand for Project Config Loading

Source: https://github.com/windwp/nvim-projectconfig/blob/master/README.md

This Lua snippet enables an autocommand that automatically loads project configurations when changing directories within Neovim.

```lua
require('nvim-projectconfig').setup({autocmd=true})
```

--------------------------------

### Manually Load Project Configuration

Source: https://context7.com/windwp/nvim-projectconfig/llms.txt

The `load_project_config()` function allows for manual reloading of the project configuration for the current directory. It can also accept an options table to override default settings, such as disabling silent mode to show notifications during the reload process.

```lua
-- Manually reload the current project's config
require('nvim-projectconfig').load_project_config()

-- Reload with temporary option overrides
require('nvim-projectconfig').load_project_config({
  silent = false  -- Show notification this time
})
```

--------------------------------

### Load Project-Specific JSON Data

Source: https://context7.com/windwp/nvim-projectconfig/llms.txt

The `load_json()` function reads and parses a JSON configuration file associated with the current project. It returns a Lua table containing the parsed data if the file exists and is valid JSON; otherwise, it returns `nil`. This allows for easy access to project-specific settings stored in JSON format.

```lua
-- Load project-specific JSON data
local project_data = require('nvim-projectconfig').load_json()

if project_data then
  -- Access your stored project settings
  print('Last opened file: ' .. (project_data.last_file or 'none'))
  print('Project type: ' .. (project_data.type or 'unknown'))

  -- Use settings in your workflow
  if project_data.run_command then
    vim.keymap.set('n', '<leader>r', function()
      vim.cmd('!' .. project_data.run_command)
    end, { desc = 'Run project command' })
  end
else
  print('No JSON config found for this project')
end
```

--------------------------------

### Load and Save JSON Data

Source: https://github.com/windwp/nvim-projectconfig/blob/master/README.md

These Lua snippets provide functions to load and save JSON data using the nvim-projectconfig plugin.

```lua
require('nvim-projectconfig').load_json()
```

```lua
require('nvim-projectconfig').save_json(data)
```

--------------------------------

### Save Project Configuration to JSON (Lua)

Source: https://context7.com/windwp/nvim-projectconfig/llms.txt

The save_json() function persists a Lua table as JSON to the project's configuration file. This function is useful for storing project-specific state or settings that need to persist across Neovim sessions. It takes a Lua table as input and saves it to a JSON file.

```lua
local pc = require('nvim-projectconfig')

-- Save project-specific data
pc.save_json({
  last_file = vim.fn.expand('%:p'),
  cursor_position = vim.api.nvim_win_get_cursor(0),
  type = 'nodejs',
  run_command = 'npm run dev',
  test_command = 'npm test',
  custom_settings = {
    use_prettier = true,
    eslint_fix_on_save = true
  }
})

-- Example: Auto-save last position on exit
vim.api.nvim_create_autocmd('VimLeavePre', {
  callback = function()
    local data = pc.load_json() or {}
    data.last_file = vim.fn.expand('%:p')
    data.last_position = vim.api.nvim_win_get_cursor(0)
    pc.save_json(data)
  end
})
```
