在 go 中逐行读取文件

I'm unable to find file.ReadLine function in Go. I can figure out how to quickly write one, but just wondering if I'm overlooking something here. How does one read a file line by line?

    There is function ReadLine in package bufio.

    Please note that if the line does not fit into the read buffer, the function will return an incomplete line. If you want to always read a whole line in your program by a single call to a function, you will need to encapsulate the ReadLine function into your own function which calls ReadLine in a for-loop.

    bufio.ReadString('\n') isn't fully equivalent to ReadLine because ReadString is unable to handle the case when the last line of a file does not end with the newline character.
