Built-in LSP workflows

Use Neovim’s built-in LSP features for semantic code navigation.

Go to definition

Jump to the definition of the symbol under cursor.

↗#

luaANYneovimlspnavigation

lua

vim.keymap.set("n", "gd", vim.lsp.buf.definition)

A core LSP navigation mapping.

Find references

List all references to a symbol.

↗#

luaANYneovimlspreferences

lua

vim.keymap.set("n", "gr", vim.lsp.buf.references)

Helpful for refactors and impact analysis.

Show hover docs

Display hover information from the language server.

↗#

luaANYneovimlspdocs

lua

vim.keymap.set("n", "K", vim.lsp.buf.hover)

Commonly used for signatures, docs, and type details.

Rename a symbol

Perform a semantic rename through LSP.

↗#

luaANYneovimlsprefactor

lua

vim.keymap.set("n", "<leader>rn", vim.lsp.buf.rename)

Safer and broader than plain text replacement.

Treesitter

Enable structural parsing for better highlighting and editing.

Configure nvim-treesitter

Install parsers and enable syntax-aware modules.

↗#

luaANYneovimtreesittersyntax

lua

require("nvim-treesitter.configs").setup({
  ensure_installed = { "lua", "vim", "javascript", "typescript" },
  highlight = { enable = true },
  indent = { enable = true },
})

Treesitter improves syntax-aware highlighting and related editor features.

Use Treesitter textobjects

Select functions and classes structurally.

↗#

luaANYneovimtreesittertextobjects

lua

-- usually configured via nvim-treesitter-textobjects

Treesitter textobjects can make editing much more semantic.

Plugins and health checks

Install and organize plugins cleanly in modern Neovim.

Bootstrap lazy.nvim

Clone lazy.nvim automatically if missing.

↗#

luaANYneovimpluginslazy-nvim

lua

local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({ "git", "clone", "--filter=blob:none", "https://github.com/folke/lazy.nvim.git", lazypath })
end
vim.opt.rtp:prepend(lazypath)

A common modern bootstrap pattern for plugin management.

Declare plugins with lazy.nvim

↗#

luaANYneovimpluginslazy-nvim

lua

require("lazy").setup({
  { "nvim-treesitter/nvim-treesitter" },
  { "neovim/nvim-lspconfig" },
  { "nvim-telescope/telescope.nvim", dependencies = { "nvim-lua/plenary.nvim" } },
})
