在LSP中徘徊时，如何在光标下方获取单词？

我正在为编程语言制作VSCODE扩展。起初，我使用扩展API进行了所有工作。现在我想切换LSP。我实施的功能是显示了悬停在内置功能的定义。

这是代码：

vscode.languages.registerHoverProvider("lc", {
        provideHover(document, position) {
            const word = document.getText(
                document.getWordRangeAtPosition(position, /\b\w+(?=\(.*\))/)
            );
            if (builtin_funcs[word] != undefined) {
                return new vscode.Hover(
                    new vscode.MarkdownString(`${builtin_funcs[word]}`)
                );
            } else {
                return null;
            }
        },
    });

我使用getWordRangeAtposition使用Regex /\ b \ w+（？= \（。*\））/来匹配函数。获取功能名称后，我在indentin_funcs数组中搜索了它，然后返回了定义。

，我想将其移植到LSP，但是我找不到getWordRangeatPosition函数等效。

I am making a vscode extension for a programming language. At first i was doing all of the work using the extension api. Now i want to switch LSP. The feature I had implemented was that show the definition of builtin functions on hover.

This was the code:

vscode.languages.registerHoverProvider("lc", {
        provideHover(document, position) {
            const word = document.getText(
                document.getWordRangeAtPosition(position, /\b\w+(?=\(.*\))/)
            );
            if (builtin_funcs[word] != undefined) {
                return new vscode.Hover(
                    new vscode.MarkdownString(`${builtin_funcs[word]}`)
                );
            } else {
                return null;
            }
        },
    });

i was using the getWordRangeAtPosition function with the regex /\b\w+(?=\(.*\))/ to match functions. After getting the function name i searched it in the builtin_funcs array and returned the definition.
