Settings from client and .luarc.json not getting merged

How are you using the lua-language-server?

Expected Behaviour

Global settings from the client and local settings from the .luarc.json file should get merged. In my case I have the following .luarc.json:

{
	"$schema": "https://raw.githubusercontent.com/LuaLS/vscode-lua/master/setting/schema.json",
  	"workspace.ignoreDir": ["test/xdg"]
}

There is no workspace.ignoreDir setting in my client config.

Actual Behaviour

The settings from .luarc.json are not applied. I have to add the ignoreDir setting to my client configuration for it to do something.

Additional Notes

I am testing a Neovim plugin (HiPhish/rainbow-delimiters.nvim), and the test setup requires me to place a symlink to the plugin root directory inside on of its sub-directories (rainbow-delimiters). When the language server starts scanning the plugin directory it ends up running in circles. Adding this directory to the ingoreDir list stops the infinite loop and the language server can scan all files normally.

I cannot place all my settings inside the local .luarc.json because the settings for Neovim configuration and plugin development cannot be known ahead of time, they must be generated. I can place the workspace.ignoreDir setting in my own client configuration, but this won't help people who want to contribute to my plugin.

What I need is for the language server to merge both configurations into one. The order should be from least to most significant:

1. client configuration
2. local configuration
3. custom configuration file (maybe?)

首先跟踪 language server 如何加载并合并客户端设置与 .luarc.json，重点关注 workspace.ignoreDir。使用附加的 logs 确认应用了哪个配置，以及合并在哪里停止。当客户端设置和本地设置遵循所要求的优先级，并且有一个 regression test 覆盖来自两个来源的 workspace.ignoreDir 时，即视为完成。
