我想用我的终端测试clangd，但我无法提出请求。我已经阅读了 LSP 语言的文档，但我仍然不明白如何启动连接等。

以下是开场信息：

clangd is a language server that provides IDE-like features to editors.

It should be used via an editor plugin rather than invoked directly. For more information, see:
        https://clangd.llvm.org/
        https://microsoft.github.io/language-server-protocol/

clangd accepts flags on the commandline, and in the CLANGD_FLAGS environment variable.

I[12:27:23.132] clangd version 13.0.0 (ssh://git@git.jetbrains.team/llvm/llvm-project.git f453b8779f319ecd0e7f6f2fdd5e78ec375aaa47 based on LLVM 1d42ba254fa3203f1ad5916ed414a84312f5bba9 revision)

I[12:27:23.148] Starting LSP over stdin/stdout

之后，我无法发送消息。

您必须阅读https://microsoft.github.io/language-server-protocol/specifications/specification-current/#headerPart并使用 json-rpc 协议向进程的标准输入发送消息。例如：

send() { msg=$(jq -n "$@"); printf "%s\r\n" "Content-Length: ${#msg}" "" "$msg" | tee /dev/stderr; }
send '{ jsonrpc: "2.0", id: 1, method: "exit" }' | clangd
