Python Force Git Hook Server Side Output On Same Line In Realtime

git hooks server side output only transmits on a newline. I want to configure a custom task and print real-time output on the same line. How can I achieve that? I tried sys.stdout.

Solution 1:

The problem comes down to the fact that Git itself does not print accumulated remote: text until the remote sends either a newline or carriage return.

Hence, if we change your inner loop to read:

for i in range(1, 15):
    sys.stdout.write('.' * i + '\r')
    sys.stdout.flush()
    time.sleep(0.5)

you will see the effect you desire.

Note that the \r moves the print position back to just after the word remote:, so we must repeat what we have printed so far (hence the need to print first one ., then two .s, then three, and so on).
