使用 vscode 扩展 api 解析一个txt文档

Question

I'm trying to write a vscode extension where I can open a txt file, and parse through the contents of that txt file line by line, and be able to search for specific key words from each line. I've been looking at the TextDocument in the vscode api, but I'm a little confused on implementing it.

How can I parse through a txt document line by line?

Thank you!

const { activeTextEditor } = vscode.window;
if (!activeTextEditor) return;
const lines = activeTextEditor.document.getText().split('\n');
for (let i = 0; i < lines.length; i++) {
    const line = lines[i];
    console.log(i, line);
}
