如何标记语法，例如在 monaco.editor.tokenize 中用于扩展 [英] How to tokenize grammars, like in monaco.editor.tokenize for use in extension

问题描述

我使用了 tokenizer在摩纳哥，但我没有看到它可以在 vscode 中访问.这对完成/签名帮助提供者很有帮助，我如何标记语法?

I have used the tokenizer in monaco but I do not see that it is accessible in vscode. This would be helpful for completion/signature help providers, how can I tokenize a grammar?

推荐答案

目前似乎没有正式的方法来执行此操作.有一个开放的功能请求，用于在此处的某个位置添加检索 tmLanguage 范围的功能:#580

It doesn't seem like there's an official way of doing this right now. There is an open feature request for adding the ability to retrieve tmLanguage scopes at a position here: #580

有一种可能的解决方法，它需要向 scope- 添加依赖项-信息 扩展名.此扩展公开了其他扩展可以使用的自己的 API.这是一个代码示例作者在链接问题中发布:

There is one potential workaround, which requires adding a dependency to the scope-info extension. This extension exposes an API of its own that other extension can use. Here's a code example posted by the author in the linked issue:

import * as api from 'scope-info'
async function example(doc : vscode.TextDocument, pos: vscode.Position) {
    const siExt = vscode.extensions.getExtension<api.ScopeInfoAPI>('siegebell.scope-info');
    const si = await siExt.activate();
    const t1 : api.Token = si.getScopeAt(doc, pos);
}

更新:不幸的是，范围信息看起来像 不再与当前的 VSCode 版本兼容.

Update: unfortunately, it looks like scope-info is no longer compatible with current VSCode versions.
