Configuring c++ on neovim
https://www.youtube.com/watch?v=lsFoZIg-oDs

- Installing clangd(LSP)
  In ensure_installed section then type `:MasonInstallAll`.
  In lspconfig.lua add this 
  ```lua
	lspconfig.clangd.setup{
	  on_attach=on_attach,
	  capabilities=capabilities,
	  init_options={
			preferences={
				disableSuggestions=true,
			}
		}
	}

	```
	Add instead this in `lspconfig.lua` to remove warning
	```lua
		local cmp_nvim_lsp = require "cmp_nvim_lsp"

	require("lspconfig").clangd.setup {
	  on_attach = on_attach,
	  capabilities = cmp_nvim_lsp.default_capabilities(),
	  cmd = {
		"clangd",
		"--offset-encoding=utf-16",
	  },
	}

	```
	
- Autoformatter
  Install clang-format. Add following in `plugins.lua`
  ```lua
	{
    "jose-elias-alvarez/null-ls.nvim",
    event="VeryLazy",
    opts=function ()
      return require "custom.configs.null-ls"
    end,
  },

	```
	Create `~/.config/nvim/lua/custom/configs/null-ls.lua`
	and type this
	```lua
	local null_ls= require("null-ls")

	local opts={
	  sources={
		null_ls.builtins.formatting.clang_format,
	  }
	}

	return opts
	```
	Press space and type `fm` to format it
	To have a custom file formatting we need to have `.clang-format` in out project folder. Generate using this
	`~/.local/share/nvim/mason/bin/clang-format --style GNU --dump-config > .clang-format`
	
- Setup	autoformat on save
  In `null-ls.lua` file
  modify it like this
  ```lua
	local augroup=vim.api.nvim_create_augroup("LspFormatting",{})
	local null_ls= require("null-ls")

	local opts={
	  sources={
		null_ls.builtins.formatting.clang_format,
	  },
	  on_attach=function (client,bufnr)
		if client.supports_method("textDocument/formatting") then
		  vim.api.nvim_clear_autocmds({
			group=augroup,
			buffer=bufnr,
		  })
		  vim.api.nvim_create_autocmd("BufWritePre",{
			group=augroup,
			buffer=bufnr,
			callback=function ()
			  vim.lsp.buf.format({bufnr=bufnr})
			end,
		  })
	  end
	  end,
	}

	return opts
	```
	
- Debugger
  With mason, install `codelldb` plugin too.
  To able to debug them use `--debug` flag after gcc command when compiling like this
  `gcc --debug main.cpp -o main`
  And when running debugger mention name of executable file ie `main` here
  	In `plugins.lua` add this
	```lua
	{
    "mfussenegger/nvim-dap",
    config=function (_, _)
      require("core.utils").load_mappings("dap")
    end
  },
	-- Also add this
	 {
    "jay-babu/mason-nvim-dap.nvim",
    event="VeryLazy",
    dependencies={
      "williamboman/mason.nvim",
      "mfussenegger/nvim-dap",
    },
    opts={
      handlers={}
    },
  },
	-- Add nvim-dap-ui too from javascript debugger too



	```
	
  Also changes in `chadrc.lua` and add `mappings.lua` like with js debugger too
