Sanitize dates in podcast title with groovy + jid3lib

When I sort the podcasts I download by their ID3 titles, I want to see an older episode sorted after a newer episode.

Here is a groovy script that modifies the MP3 title of an MP3 file passed as first parameter of the script, and replaces any dd.mm.20yy date by a 20yy.mm.dd date. It also moves the date at the beginning of the title.

You need the Java ID3 Tag Library (jid3lib) and an embeddable Groovy (groovy-all.jar)

Now in order to run the script after each download, your podcast receiver must be able to run a custom command after each download. You can use Juice.

So here is a quick and dirty script sanitize_dates.groovy :

<br />import org.farng.mp3.*<br /><br />TagOptionSingleton.getInstance().setOriginalSavedAfterAdjustingID3v2Padding(false)<br /><br />def readMp3Title(filepath) {<br /> def mp3file = new MP3File(filepath) <br /> mp3file.getID3v2Tag().getSongTitle()<br />}<br /><br />def writeMp3Title(filepath,title) {<br /> def mp3file = new MP3File(filepath) <br /> mp3file.getID3v2Tag().setSongTitle(title)<br /> mp3file.save()<br />}<br /><br />def sanitizeTitle(title,action) {<br /> def m = (title =~ /^(.*)([0-9][0-9])\.([0-9][0-9])\.(20[0-9][0-9])(.*)$/)<br /> if(m){<br /> def g = m[0]<br /> action("" + g[4] + "." + g[3] + "." + g[2] + " " + g[1] + g[5])<br /> }<br />}<br /><br /><br />def filepath = args[0]<br />def title = readMp3Title(filepath)<br /><br />println "Original title:${title}"<br />sanitizeTitle(title) { sanitizedTitle -><br /> writeMp3Title(filepath,sanitizedTitle)<br /> println "Title after sanitization:${readMp3Title(filepath)}"<br />}<br /><br /><br />

In the preferences of Juice you can use Run this command after each download with for exemple :

<br />/usr/bin/java -cp /home/me/javalibs/groovy-all.jar:/home/me/javalibs/jid3lib.jar groovy.lang.GroovyShell /home/me/bin/sanitize_dates.groovy "%f"<br />

MTP Mp3 players and Asus eee

Works like a charm :

Open a console : CTRL+ALT+T then
sudo apt-get install libmtp libnjb gnomad2
./gnomad2

Does not work with Amarok though, as the MTP support does not seem to be compiled in the version provided with the eee.

MTP devices, udev and permissions in Ubuntu Dapper

I had to install Gnomad2 in Ubuntu Dapper in order to upload files to my MTP Mp3 player.

I followed this great How To

However Gnomad2 could not open the device unless I was root (same thing for mtp-detect)

It looked like a permission problem in /dev/bus/usb

This worked for me :

In /etc/udev/rules.d/40-permissions.rules I changed

# USB devices (usbfs replacement)
SUBSYSTEM=="usb_device", MODE="0664"
to

# USB devices (usbfs replacement)
SUBSYSTEM=="usb_device", MODE="0664", GROUP="plugdev"

Then

sudo /etc/init.d/udev restart
