It's a protocol that helps editors -- and language tooling communicate in a standardized fashion. -- -- In general, you have a "server" which is some tool built to understand a particular -- language (such as `gopls`, `lua_ls`, `rust_analyzer`, etc). These Language Servers -- (sometimes called LSP servers, but that's kind of like ATM Machine) are standalone -- processes that communicate with some "client" - in this case, Neovim! -- -- LSP provides Neovim with features like: -- - Go to definition -- - Find references -- - Autocompletion -- - Symbol Search -- - and more! -- -- Thus, Language Servers are external tools that must be installed separately from -- Neovim. This is where `mason` and related plugins come into play. -- -- If you're wondering about lsp vs treesitter, you can check out the wonderfully -- and elegantly composed help section, :help lsp-vs-treesitter -- This function gets run when an LSP attaches to a particular buffer. -- That is to say, every time a new file is opened that is associated with -- an lsp (for example, opening `main.rs` is associated with `rust_analyzer`) this -- function will be executed to configure the current buffer vim.api.nvim_create_autocmd('LspAttach', { group = vim.api.nvim_create_augroup('kickstart-lsp-attach', { clear = true }), callback = function(event) -- NOTE: Remember that lua is a real programming language, and as such it is possible -- to define small helper and utility functions so you don't have to repeat yourself -- many times. -- -- In this case, we create a function that lets us more easily define mappings specific -- for LSP related items.
