typescript - 在 Visual Studio Code 文档中设置选择范围

Question

我在扩展中有一个命令，在运行命令之前，我想更改选择范围以获取整行...

const sel = textEditor.selection;
const firstLine = textEditor.document.lineAt(sel.start.line);
const lastLine = textEditor.document.lineAt(sel.end.line);

const range = new vscode.Range(firstLine.lineNumber, firstLine.range.start.character, lastLine.lineNumber, lastLine.range.end.character);

我创建了一个新范围，但我不知道如何将文档的选择设置为新范围...

Answer 1

new Selection()有 2 个重载(2 或 4 个参数):

Selection(anchor: vscode.Position, active: vscode.Position)

Selection(anchorLine: number, anchorCharacter: number, activeLine: number, activeCharacter: number)

示例，使用 4 个参数:

textEditor.selection = new vscode.Selection(firstLine.lineNumber, firstLine.range.start.character, 
lastLine.lineNumber, lastLine.range.end.character)

要制作多个光标，您需要设置 textEditor.selections

textEditor.selections = [
    new vscode.Selection(0, 0, 0, 10),
    new vscode.Selection(1, 0, 1, 10),
];
