开发VSCode扩展时获取当前活动文件的目录

const vscode = require('vscode');

function activate(context) {
    let disposable = vscode.commands.registerCommand('extension.getCurrentFileDirectory', function () {
        let activeEditor = vscode.window.activeTextEditor;
        if (activeEditor) {
            let currentFileUri = activeEditor.document.uri;
            let currentFileDir = vscode.workspace.getWorkspaceFolder(currentFileUri);
            vscode.window.showInformationMessage(`Current file directory: ${currentFileDir.uri.fsPath}`);
        } else {
            vscode.window.showInformationMessage('No active file.');
        }
    });

    context.subscriptions.push(disposable);
}
exports.activate = activate;
