“tail -f”-like generator

Question

I had this convenient function in Python:

def follow(path):
    with open(self.path) as lines:
        lines.seek(0, 2)  # seek to EOF

        while True:
          


        

Answer 1

Check out this Go package for reading from continuously updated files (tail -f): https://github.com/hpcloud/tail

t, err := tail.TailFile("filename", tail.Config{Follow: true})
for line := range t.Lines {
    fmt.Println(line.Text)
}
