Add pre-push hook.

[alexcouper]

I want to play "push it" by salt n pepa on every push.

I'm having difficulty forking the process into the background so that the push doesn't wait for the end of the song before exiting.

#!/bin/bash

#mplayer -really-quiet /Users/alex/pushit_small.mp3 >&- 2>&- &
mplayer -really-quiet /Users/alex/pushit_small.mp3 >&- 2>&- & disown
#nohup mplayer -really-quiet -cache 8192 -vo null - /Users/alex/pushit_small.mp3 > /dev/null 2>&1 &
#mplayer -really-quiet /Users/alex/pushit_small.mp3 <&- >&- 2>&- & disown
#mplayer -really-quiet /Users/alex/pushit_small.mp3 & disown
#mplayer -really-quiet /Users/alex/pushit_small.mp3 >/dev/null 2>&1 &
echo "done"
exit 0

None of the above exit before the mp3 (a 10 second sample) has finished. Although they do echo "done"

Largely courtesy of @oddbloke:

Generating the awesome push it clip:

curl -s "$(youtube-dl -g http://www.youtube.com/watch\?v\=vCadcBR95oU -k)" > pushit
ffmpeg -i pushit pushit.wav
sox pushit.wav pushit_small.mp3 trim 1:56 10 fade 0:1 0 0:4

[koddsson]

I changed the curl/ffmpeg commands into this: youtube-dl http://www.youtube.com/watch\?v\=vCadcBR95oU -qckx --audio-format wav -o pushit.wav

[koddsson]

Sorry that actually doesn't extract the audio from the video

[alexcouper]

Another one I want, probably on nosetests not returning an error:

curl -s "$(youtube-dl -g https://www.youtube.com/watch\?v\=fm660vIn8Tg -k)" > vid
ffmpeg -i vid vid.wav
sox vid.wav vid.mp3 trim 0:11 19 fade 0:1 0 0:2

[koddsson]

I messed around with a bunch of methods to achieve background music playing in the terminal and nothing seemed to work on my machine. My only thought now is doing all these operations in python (import youtube-dl as a library, slicing up the audio using some other library and then playing it) and forking that python script to the background.

[alexcouper]

I have this script:

$ cat .git/hooks/pre-push
#!/bin/bash

mplayer -really-quiet /Users/alex/pushit_small.mp3 >&- 2>&- & disown
echo "done"
exit 0

If I run .git/hooks/pre-push directly from the command line it works. As in, the music starts and I am given the console before the music finishes.

It's just that from the hook it fails. As in when run with git push

[koddsson]

Does it fail in the sense that it hangs or in the sense that it doesn't play the clip?

[alexcouper]

Yes, sorry - it fails in the sense that it hangs whilst playing the clip - and only returns to the console after that.

[ikornaselur]

Have you tried running a python script that spawns a subprocess?

For example

from subprocess import Popen

Popen(["mplayer", "-really-quiet", "vid.mp3"])

I have no idea if this works as a git hook, but this runs in a few milliseconds for me and returns to my shell with the audio playing in the background. I can even kill the shell that ran the python process.

[koddsson]

I can confirm that @Ikornaselur's solution works

[alexcouper]

@koddsson I beg to differ.

$ cat .git/hooks/pre-push
#!/usr/bin/env python

import sys
from subprocess import Popen

Popen(["mplayer", "-really-quiet", "/Users/alex/pushit_small.mp3"])
sys.exit(0)

When I run: git push

I have to wait for the tune to play before getting terminal access again.

[koddsson]

Huh, that's weird. Works on my ubuntu 14.04. Maybe you need to upgrade to a better OS.

[koddsson]

All jokes aside maybe we can compare how it works on our different machines tomorrow at work.

[OddBloke]

Yeah, I haven't had any problems with backgrounding the hook on my Debian machine.

[OddBloke]

One potential solution to try: daemonising the process that calls mplayer.

[alexcouper]

Closing on account of impossibility on mac.

For reasons that are beyond me.

[jeremykenedy]

Hi,

You can use quicktime to snip your mp3 and the native mac command line player to play it from command line.

Please see below.

#!/bin/bash

## ADD VARIABLES HERE ##
_yourSoundFileAndPath="/Users/jeremykenedy/Desktop/pushit-jk-master/pushit8s.m4a"

## ADD ALIAS'S HERE ##
alias pushitmaster="git push origin master;afplay "$_yourSoundFileAndPath

I also created a repo @ https://github.com/jeremykenedy/pushit

Yay !

Jeremy :)

[alexcouper]

Nice @jeremykenedy - I'll see if afplay suffers from the same behaviour as mplayer when combined with a git hook.

[alexcouper]

yeah unfortunately it looks like alias-ing is the only way to get this to work on mac.

Somehow (I have no idea how) the git push waits for the script to play despite the process being forked.
