v0.5.0

What's Changed

Features

LSP

• Add language server setup with inlay hints, code lenses and toggle keymaps by @nmfirdausw in #5

Highlights

• Language servers. A new lsp option enables servers through Neovim's native vim.lsp.config() and vim.lsp.enable().
• Bring your own configs. Use nvim-lspconfig, which Batu can install for you, or write your own in lsp/<name>.lua.
• Inlay hints and code lenses. Each turns on in buffers whose server supports it.
• Toggle keymaps. grh and grl toggle inlay hints and code lenses per buffer.
• Native. Batu installs no servers and adds no dependencies beyond the optional nvim-lspconfig.

Usage

require("batu").setup({
  lsp = {
    lspconfig = true,
    servers = {
      lua_ls = true,                                             -- use the config Neovim finds
      gopls = { settings = { gopls = { staticcheck = true } } }, -- merge on top of it
      pyright = false,                                           -- skip
    },
    inlay_hints = true,
    codelens = true,
  },
})

Option	Value	Effect
lsp	false (default)	Do nothing
	a table	Set up language servers with the options below
lsp.lspconfig	false (default)	Leave server configs to you, in lsp/<name>.lua
	true	Install and load nvim-lspconfig with vim.pack
lsp.servers	a table	Servers to enable, by name. true uses the config Neovim finds, a table is merged on top of it, false skips the server
lsp.inlay_hints	false (default)	Don't enable inlay hints
	true	Enable them where the server supports it
lsp.codelens	false (default)	Don't enable code lenses
	true	Enable them where the server supports it
lsp.keymaps	true (default)	Set the toggle keymaps below
	false	Set none

Keymaps

Mode	Key	Action
n	grh	Toggle inlay hints in the buffer
n	grl	Toggle code lenses in the buffer

Both are set only in buffers whose server supports the feature. Neither clashes with Neovim's own gr* maps, and grx still runs the code lens on the current line.

How it works

Batu enables a feature when the server attaches, after checking that the server supports it. A server table such as lua_ls = require("lsp.lua_ls") is passed to vim.lsp.config() and then enabled.

Batu sets no diagnostic config, which is left for a later release.

Upgrading

Nothing changes for existing configs. lsp is off by default, so setup() does not enable any server or set any keymap until you pass an lsp table.
