Clojure command-line library designed to make it easy to manipulate/cleanup bad mp3 tag with UTF-8 support

clj-audiotagger

Clojure library designed to make it easy to manipulate/cleanup bad mp3 tag with UTF-8 support.

Design with simplicity in mind so out of the box it can do the following:

• Set the file name as title of the mp3 track
• Set the track index to current position in the list e.g. track/track-total based on the current position
• Set common tags shared by all the files (e.g. same artist, album, genre, etc)

Built on top of the two useful library

• claudio (Clojure)
• jaudiotagger (Java)

Basic Usage

Will be provided the easy way to run this later for now please see below.

Development

Available via clojars.org/clj-audiotagger

• Leiningen

[clj-audiotagger "0.2.0"]

• Gradle

compile "clj-audiotagger:clj-audiotagger:0.2.0"

• Maven

<dependency>
  <groupId>clj-audiotagger</groupId>
  <artifactId>clj-audiotagger</artifactId>
  <version>0.2.0</version>
</dependency>

Pre-requisite

• Java SDK
• Clojure
• Leiningen

Installation

• Clone the repository

# clone the repository
mkdir -p ~/projects

# clone the repository
git clone [email protected]:agilecreativity/clj-audiotagger.git ~/projects

# Generate the standalone binary (to be installed to `~/bin`)
mkdir -p ~/bin

# Now build the standalone executable using [lein-bin]
lein bin

You should get output like the following:

$lein bin
Created /home/bchoomnuan/codes/others/clj-audiotagger/target/clj-audiotagger-0.2.0.jar
Created /home/bchoomnuan/codes/others/clj-audiotagger/target/clj-audiotagger-0.2.0-standalone.jar
Creating standalone executable: /home/bchoomnuan/codes/others/clj-audiotagger/target/clj-audiotagger
Copying binary to #object[java.io.File 0x3cc79c02 /home/bchoomnuan/bin]

Note that the executable is called clj-audiotagger and is automatically copied to ~/bin/clj-audiotagger

Basic Usage

Assume that the ~/bin is in your $PATH

# Run the command without any options will print default usage

~/bin/clj-audiotagger`

# Or if ~/bin is your executable path you could just type
clj-audiotagger

Which should produce something like:

Update mp3 id3 tag using simple rules.

Usage: clj_audiotagger [options]
  -b, --base-dir DIR             .  The staring directory
  -f, --file-name-as-title          Use file name as title
  -t, --position-as-track-order     Use position as track order
  -u, --set-shared-tags             Update shared tags
  -c, --cover COVER_FILE            The shared cover file that will be updated to
  -h, --help

Options:

--base-dir DIR starting directory
--cover COVER_FILE the shared cover file if any
--filename-as-title
--position-as-track-order
--set-shared-tags tags
  title   TITLE
  album   ALBUM
  artist  ARTIST
  genre   GENRE
  year    YEAR
  comment COMMENT

Please refer to the manual page for more information.

Sample Usage

• To rename all the mp3 files to the filename try

clj-audiotagger --base-dir ~/media/mp3s --file-name-as-title

• To update the play index try

# long version
clj-audiotagger --base-dir ~/media/mp3s --position-as-track-order

# Or short version
clj-audiotagger -b ~/media/mp3s -t

• To update the common attributes of a given list of files

e.g. Good use-case if have the media sharing the same type of attribute (artist, album, year)

# Using short version of the command
clj-audiotagger -b ~/media/mp3s -u album "Metallica Greatest Hits" artist "Metallica" comment "My fav band"

for list of the attribute please see claudio for attribute you can set.

The common values are:

title   TITLE
album   ALBUM
artist  ARTIST
genre   GENRE
year    YEAR
comment COMMENT

• To update the cover image for all files in a given directory (both jpg and png are supported)

# If you have the png file
clj-audiotagger -b ~/media/mp3s \
                -u album "Metallica Greatest Hits" artist "Metallica" comment "My fav band" \
                -c music/metallica-cover.png

# If you have the jpg file
clj-audiotagger -b ~/media/mp3s \
                -u album "Continuum" artist "John Mayer" \
                -c music/john-mayer.jpg

Roadmaps/Todos

• Add documentation on how to run it with lein-bin
• Add the ability to update of cover image for a file
