nlsp-settings.nvim

A plugin to configure Neovim LSP using json/yaml files like coc-settings.json.

_{Using nlsp-settings.nvim and lspconfig and jsonls and nvim-compe and vim-vsnip}

Using nlsp-settings.nvim, you can write some of the settings to be passed to lspconfig.xxx.setup() in a json file. You can also use it with jsonls to complete the configuration values.

Requirements

• Neovim
• neovim/nvim-lspconfig

Installation

Plug 'neovim/nvim-lspconfig'
Plug 'tamago324/nlsp-settings.nvim'

" Recommend
Plug 'williamboman/mason.nvim'
Plug 'williamboman/mason-lspconfig.nvim'

" Optional
Plug 'rcarriga/nvim-notify'

Getting Started

Step1. Install jsonls with mason.nvim

:MasonInstall json-lsp

Step2. Setup LSP servers

Example: Completion using omnifunc

local mason = require("mason")
local mason_lspconfig = require("mason-lspconfig")
local lspconfig = require("lspconfig")
local nlspsettings = require("nlspsettings")

nlspsettings.setup({
  config_home = vim.fn.stdpath('config') .. '/nlsp-settings',
  local_settings_dir = ".nlsp-settings",
  local_settings_root_markers_fallback = { '.git' },
  append_default_schemas = true,
  loader = 'json'
})

function on_attach(client, bufnr)
  local function buf_set_option(...) vim.api.nvim_buf_set_option(bufnr, ...) end
  buf_set_option('omnifunc', 'v:lua.vim.lsp.omnifunc')
end

local global_capabilities = vim.lsp.protocol.make_client_capabilities()
global_capabilities.textDocument.completion.completionItem.snippetSupport = true

lspconfig.util.default_config = vim.tbl_extend("force", lspconfig.util.default_config, {
  capabilities = global_capabilities,
})

mason.setup()
mason_lspconfig.setup()
mason_lspconfig.setup_handlers({
  function (server_name)
    lspconfig[server_name].setup({
      on_attach = on_attach
    })
  end
})

Step3. Write settings

Execute :LspSettings sumneko_lua.
sumneko_lua.json will be created under the directory set in config_home. Type <C-x><C-o>. You should now have jsonls completion enabled.

Usage

LspSettings command

• :LspSettings [server_name]: Open the global settings file for the specified {server_name}.
• :LspSettings buffer: Open the global settings file that matches the current buffer.
• :LspSettings local [server_name]: Open the local settings file of the specified {server_name} corresponding to the cwd.
• :LspSettings local buffer or LspSettings buffer local: Open the local settings file of the server corresponding to the current buffer.
• :LspSettings update [server_name]: Update the setting values for the specified {server_name}.

For a list of language servers that have JSON Schema, see here.

Settings files for each project

You can create a settings file for each project with the following command.

• :LspSettings local [server_name].
• :LspSettings update [server_name]

The settings file will be created in {project_path}/.nlsp-settings/{server_name}.json.

Combine with Lua configuration

It is still possible to write settings in lua. However, if you have the same key, the value in the JSON file will take precedence.

Example) Write sumneko_lua settings in Lua

local mason = require("mason")
local mason_lspconfig = require("mason-lspconfig")
local lspconfig = require("lspconfig")

local server_opts = {}

-- lua
server_opts.sumneko_lua = {
  settings = {
    Lua = {
      workspace = {
        library = {
          [vim.fn.expand("$VIMRUNTIME/lua")] = true,
          [vim.fn.stdpath("config") .. '/lua'] = true,
        }
      }
    }
  }
}

local common_setup_opts = {
  -- on_attach = on_attach,
  -- capabilities = require('cmp_nvim_lsp').update_capabilities(
  --   vim.lsp.protocol.make_client_capabilities()
  -- )
}

mason.setup()
mason_lspconfig.setup()
mason_lspconfig.setup_handlers({
  function (server_name)
    local opts = vim.deepcopy(common_setup_opts)
    if server_opts[server_name] then
      opts = vim.tbl_deep_extend('force', opts, server_opts[server_name])
    end
    lspconfig[server_name].setup(opts)
  end
})
