Introduction to Snippets

Snippets are powerful tools that allow you to quickly insert pre-defined code templates into your editor. NyxVim uses the LuaSnip plugin for handling snippets, providing a flexible and efficient snippet management system.
By default, NyxVim includes the friendly-snippets plugin, which offers a wide range of snippets for many programming languages.

​
LuaSnip Overview

LuaSnip is a snippet engine for Neovim written in Lua. It offers advanced features like:
  • Dynamic snippets
  • Conditional expansion
  • Nested snippets
  • And more!
To get the most out of LuaSnip, we recommend reading the official LuaSnip documentation.

​
Configuring Snippet Paths

NyxVim provides global variables to specify the paths for your custom snippets. You can set these in your configuration: 
-- For VSCode-style snippets (JSON files)
vim.g.vscode_snippets_path = "your/snippets/path"
vim.fn.stdpath("config") returns the path to your Neovim configuration folder.

​
Creating Custom Snippets

To create your own snippets, you can use any of the supported formats (VSCode, SnipMate, or Lua). Here’s an example of a Lua snippet: 
local ls = require("luasnip")
local s = ls.snippet
local t = ls.text_node
local i = ls.insert_node

ls.add_snippets("all", {
  s("ternary", {
    -- equivalent to "${1:cond} ? ${2:then} : ${3:else}"
    i(1, "cond"), t(" ? "), i(2, "then"), t(" : "), i(3, "else")
  })
})
This snippet creates a ternary operator template that can be used in any file type.

​
Using Snippets

To use a snippet:
  1. Enter insert mode
  2. Type the snippet trigger
  3. Press the expansion key (usually <Tab>)
You can use the :LuaSnipListAvailable command to see all available snippets for the current file type.

​
Best Practices

  1. Organize snippets: Keep your snippets organized by language or purpose.
  2. Use descriptive names: Choose clear, descriptive names for your snippets.
  3. Leverage dynamic snippets: Use Lua’s power to create dynamic, context-aware snippets.
  4. Keep snippets DRY: Avoid duplicating code in your snippets.

​
Troubleshooting

If you’re having issues with snippets:
  1. Check that the snippet path is correctly set
  2. Ensure the snippet file is in the correct format
  3. Verify that the snippet trigger is correct
  4. Use :LuaSnipListAvailable to check if the snippet is recognized
