Unusually slow indexing of lsp bridge` under clangd wrapper header file

[harisonkhlil]

emacs -Q: 下表现：

;;; debug.el --- Debugging -*- lexical-binding: t; -*-

(add-to-list 'load-path "~/.config/emacs/.local/straight/repos/lsp-bridge")

(add-to-list 'load-path "~/.config/emacs/.local/straight/repos/yasnippet")
(add-to-list 'load-path "~/.config/emacs/.local/straight/repos/markdown-mode")

(require 'yasnippet)
(yas-global-mode 1)

(require 'lsp-bridge)
(global-lsp-bridge-mode)

Index:
  StandardLibrary: Yes
CompileFlags:
  Add:
    - -std=c++2b
    - -I/opt/homebrew/opt/fmt/include
  Compiler: clang++

在没有 compile_commands.json 的情况下每一个空文件索引补全都非常缓慢，比如视频演示的 <fmt/core.h> 内容是：

// This file is only provided for compatibility and may be removed in future
// versions. Use fmt/base.h if you don't need fmt::format and fmt/format.h
// otherwise.

#include "format.h"

通过使用 lsp mode 和 eglot 都没有这个问题，能够迅速反应，按照常理来说应该不是性能问题，应该是 lsp bridge 与 clangd 的交互有关。

lsp log 如下 lsp.log

一直有报错

你应该提供 compile_commands.json， 并在你的项目中执行 git init 命令， 要不是 lsp-bridge 是针对 test.cpp 这个文件提供补全， 而不是 smalltools 这个目录
