Scripts

I can code, but mostly I write quick scripts for various purposes. I’ve become pretty infamous at work for the horrendous one-off one-line pipelines I create! I try and make actual scripts a little more readable…

denon_demon
My Denon receiver has a serial port. This serial port can be used to control and report on what the receiver is doing. So if I send it "PW?" then it will report on the power state. This daemon (written for MacOS) will listen for commands on a pipe and communicate with the receiver and write out status entries so it is easy for a program to see what is going on. It also writes out a log file.
```
Wed Feb 22 21:21:27 2012 status.Volume = 47 -33.0dB
Wed Feb 22 21:21:30 2012 status.Volume = 465 -33.5dB
Wed Feb 22 21:21:59 2012 status.MainSurround = STEREO
Wed Feb 22 21:22:00 2012 status.MainSurround = STEREO
Wed Feb 22 21:23:58 2012 status.MainSurround = STEREO
Wed Feb 22 21:24:02 2012 status.Power = STANDBY
Wed Feb 22 21:24:02 2012 status.MainZone = OFF
```

denon
A simple command client to talk to the pipe above, and report on the status of the receiver

% denon volume -25
          Input: TIVO
   MainSurround: DOLBY PL2 C
       MainZone: ON
           Mute: OFF
          Power: ON
         Volume: 55 -25.0dB
         Z2Mute: OFF
       Z2Volume: 99 ---.-dB
          Zone2: OFF
     Zone2Input: SOURCE

phone
Pulling data from Google contacts using LWP::Simple and XML::XPath rather than WWW::Google::Contacts, which has a horrendous dependency path. Since we're only reading data here we can do things more easily.
phone_droid3
I had a Droid 3 phone. This script will scp the contacts.db and then use DBD::Sqlite to read the data and present it in text format. Why am I doing this? 'Cos I'm stupid :-)
movemouse.c
OK, this is a C program and not a script, but it's small enough so... Basically moves the OS-X mouse cursor to a given co-ordinate. This is because my Mac Mini will reset the cursor to top-left frequently and when I play DVDs then this stops the application menu bar going away, so I use this to move the mouse first.
dvdplay
This is a a bash script that creates applescript to start DVD Player playing a VIDEO_TS directory.
dvd
A script that generates various small applescripts to report/control on DVD Player. Uses dvdplay to start a new DVD. So I can do "dvd pause" to pause playback.
play (iTunes 10 version)
Shell script to create applescript to create an iTunes play list to play the mp3s listed on the command line
itunes (iTunes 10 version)
A script that generates various small applescripts to report/control on iTunes. So I can do "itunes dj" to play the "iTunes DJ" playlist. Unfortunately the latest version of iTunes has broken a lot of functionality; the applescript calls don't work properly any more and a number of controls no longer have directly accessible function calls.
itunes
play
A version of the "play" and "itunes" scripts that work with Itunes 12. This includes some kludge workarounds for manipulating the shuffle and repeat settings.
airplay
A craptastic script that tries to turn on/off airplay on iTunes so that I can listen to the music on a secondary receiver. Apple don't seem to expose the AirPlay interface so this pretends to click buttons and stuff. Ugh.
virt_build
A BUILD script for KVM `virsh` to create VMs. It's a wrapper around `virt-install` to create a disk image or LVM, define the machine, kickstart boot it. Additional disks can be added to images using virt_add_disk. The CentOS 6 and CentOS 7 kickstart files.
