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.

まず、capabilities.textDocument.completion.completionItem.snippetSupport = false の状態で NeoVim の if と for の補完を再現し、次に language server の補完処理を追跡します。完了の条件は、server がその capability を尊重し、無効化されている場合に snippet の送信を停止することです。その際、個別の設定 completion.callSnippet や completion.keywordSnippet に依存してはいけません。
