vscode 扩展，设置 window.activeTextEditor [英] Vscode extension, setting window.activeTextEditor

问题描述

如何使用vscode扩展api设置activeTextEditor?

How can I use the vscode extension api to set the activeTextEditor?

我需要这个的原因是因为我的扩展依赖于对扩展 B 的外部调用，而扩展 B 不接受编辑器的参数.它只是查看 vscode.window.activeTextEditor.

The reason I need this is because my extension depends on an external call to extension B, and extension B does not take an argument for editor. It just looks at vscode.window.activeTextEditor.

我的扩展程序是一个 Web 视图，当在 Web 视图上单击某些内容时，它会调用扩展程序 B.那时，活动选项卡"是 webview，它不是我想要的 activeTextEditor.

My extension is a webview which calls Extension B when something is clicked on the webview. At that moment in time, the 'active tab' is the webview, which is not activeTextEditor that I want.

我想做类似的事情

vscode.window.activeTextEditor = editor

在我的点击处理程序开始时，但这不起作用，因为 activeTextEditor 不是一个 setter.

at the start of my click handler, but this doesn't work because activeTextEditor is not a setter.

我尝试对相关编辑器进行虚假

I tried making a fake edit on the editor in question:

function changeFocus(editor: vscode.TextEditor) {
  return editor.edit((editBuilder) => {
    const pos = new vscode.Position(0, 0);
    const nxt = new vscode.Position(0, 1);
    editBuilder.insert(pos, "\\");
    editBuilder.delete(new vscode.Range(pos, nxt));
  });
}

但这不会改变 vscode.window.activeTextEditor 变量(它仍然是 undefined).

but this does not change vscode.window.activeTextEditor variable (it is still undefined).

推荐答案

如果我理解正确，这会打开并聚焦另一个文件:

If I understand correctly, this opens and focuses another file:

const currentWorkSpace = await vscode.workspace.getWorkspaceFolder(vscode.window.activeTextEditor.document.uri);

vscode.window.showTextDocument(vscode.Uri.joinPath(currentWorkSpace.uri, 'search/oldSearch.js'), { preview: false });

它在之前保存的光标位置聚焦和可写.

It is focussed and writable at its previously saved cursor position.

showTextDocument() 有另外两种形式，其中一种形式可以将 TextDocument 作为要打开的文件，而不是 Uri.

showTextDocument() has two other forms, one of which can take a TextDocument as the file to be opened, rather than a Uri.

还有 openTextDocument() 可以根据需要创建一个新的无标题文件.

There is also openTextDocument() which can create a new untitled file if you wish.

如果文件已经打开，此代码仍将用于聚焦它，因此您拥有 activeTextEditor.

If the file is already open, this code will still serve to focus it and thus you have your activeTextEditor.
