惯用缓冲os.Stdout

Question

os.Stdout.Write() is an unbuffered write. To get a buffered write, one can use the following:

f := bufio.NewWriter(os.Stdout)
f.Write(b)

Question:

Is there a more idiomatic way to get buffered output?

Answer 1

No, that is the most idiomatic way to buffer writes to Stdout. In many cases, you will want to do also add a defer:

f := bufio.NewWriter(os.Stdout)
defer f.Flush()
f.Write(b)

This will ensure that the buffer is flushed when you return from the function.
