Disable snippets via `capabilities`?

How are you using the lua-language-server?

NeoVim

Which OS are you using?

MacOS

What is the issue affecting?

Completion

Expected Behaviour

According to the LSP spec, clients should be able to disable support for snippets by setting capabilities.textDocument.completion.completionItem.snippetSupport = false. However, lua-language-server seems to ignore this setting in favor of its own (non-standard?) settings (completion.callSnippet = "Disable" and completion.keywordSnippet = "Disable".

Actual Behaviour

Even if a user sets capabilities.textDocument.completion.completionItem.snippetSupport = false, snippets continue to be sent by the language server.

Reproduction steps

1. Set capabilities.textDocument.completion.completionItem.snippetSupport = false
2. Start typing i... or fo..
3. Snippets will be shown for if and for.

Additional Notes

Since it seems standard to disable snippets using the capabilities setting, I'm hoping that lua-language-server can support that.

No response

首先，在 capabilities.textDocument.completion.completionItem.snippetSupport = false 的情况下，在 NeoVim 中复现 if 和 for 的补全，然后跟踪语言服务器的补全处理流程。完成的标准是服务器遵守该 capability，在它被禁用时停止发送 snippets，且不依赖单独的 completion.callSnippet 或 completion.keywordSnippet 设置。
