Dnuos: Make a list!

Dnuos is a console program that creates lists of music collections, based on directory structure.

For example, a list might look like this:

Ambient | | |
Alva Noto | | |
2001 - Transform | 70.9M | MP3 | -V2 2004 - Transrapid | 30.2M | MP3 | -aps 2005 - Transspray | 31.7M | MP3 | -aps 2005 - Transvision | 32.3M | MP3 | -aps
Alva Noto and Ryuichi Sakamoto | | |
2002 - Vrioon | 72.6M | MP3 | -aps 2005 - Insen | 99.1M | MP3 | 320 C 2006 - Revep | 27.9M | MP3 | -V2n

The list format is completely customizable and can be plain text or HTML.

Dnuos supports MP3, AAC, Musepack, Ogg Vorbis, and FLAC audio files. Quality profile detection is also supported, including [LAME quality preset][] information.

Audio file information is saved to disk after a list is made for the first time, making subsequent lists much faster to generate. Only audio files and directories that have been changed since the last list was made are analyzed.

Dnuos is based on code from [Oidua][]. Oidua makes similar lists, but is much older, has fewer features, and is no longer maintained.

Releases can be found in <http://bitheap.org/dnuos/files/>.


Run dnuos --help for a full rundown of the available options.

### Linux, Mac OS X, Unix

Extract the archive and run setup.py to install it:

tar zxvf dnuos-1.0.11.tar.gz cd dnuos-1.0.11 sudo python setup.py install

This will install a console script named dnuos into /usr/local/bin. (On Mac OS X 10.4 and earlier, it may get installed into /Library/Frameworks/Python.framework/Versions/Current/bin.)

Once installed, open up your favorite terminal emulator and run dnuos. On Mac OS X, Terminal might be a good choice (located in /Applications/Utilities/).

### Windows

There's no installation. Just extract the zip file where you want to install it. You can run the program in the command prompt with dnuos.exe.

After extracting Dnuos, press the Windows key and R to bring up the Run dialog. Type cmd and press enter to start the command prompt. Then type the drive letter the .exe is on, and cd to the directory with the .exe file. From here, simply run dnuos.exe.

### Graphical Front-ends

If terminals and command prompts aren't to your liking, you can try one of the following graphical front-ends instead:

  • [dnuOSX][] - A native front-end for Mac OS X.
  • [Guidua][] - A graphical front-end for Windows.
  • [QtOIDUA][] - A graphical front-end for Linux and Mac OS X. (Note: Versions 0.08 and older have a bug which prevents QtOIDUA from working with Dnuos 1.0.)

### Version 1.0.11 (Jul. 18, 2010)

  • Fixed Unicode error crashes caused by non-Unicode file system paths.
  • Fixed MPC files not storing year tag data.
  • Improved ID3v2 tag handling performance.

### Version 1.0.10 (Feb. 13, 2009)

  • Fixed installation not working when a previous egg-based installation is present.
  • Fixed individual files not being sorted in output.
  • Fixed unfriendly traceback being presented for non-existent files and directories.
  • Added natural sorting (i.e. 9.mp3 comes before 10.mp3).
  • Added support for specifying individual files as arguments.
  • Added default format string resizing based on the terminal width. The name column will be resized so the output better fits the width of the terminal. (Unix only)
  • Added SQLite-based caching, available with Python 2.5. When used, loading the cache is much faster, and culling the cache reduces its total size.
  • More Python 2.6 compatibility improvements.
  • French translation corrections (contributed by Jean-Denis Vauguet).

### Version 1.0.9 (Sep. 20, 2008)

  • Fixed a crash when using HTML output.
  • Fixed a crash with FLAC/Ogg Vorbis tags containing equal signs.
  • Fixed --delete-cache not always deleting the cache directory.
  • Fixed directories with both LAME and non-LAME MP3s being listed with only the LAME preset quality, instead of being listed as mixed.
  • Added shorthand switch -C for --disable-cache.
  • Added the [Y] year output tag.
  • Added the [D] depth output tag back.
  • Improved Python 2.6 compatibility.
  • Added support for using the preferred encoding when outputting to the terminal. (Characters that can't be encoded are replaced with question marks.)
  • Updated French translation with corrections.
  • Fixed French translation not being installed when using easy_install.

### Version 1.0.8 (Jun. 16, 2008)

  • Fixed crashes on Unix platforms with directory names that have characters that aren't valid for the file system's character encoding.

### Version 1.0.7 (Jun. 3, 2008)

  • Added consistency improvements from the Makefile to setup.py. make isn't always available, so setup.py is now the recommended way of installing Dnuos.

### Version 1.0.6 (May 31, 2008)

  • Moved cache location on Linux from ~/.dnuos to ~/.cache/dnuos ($XDG_CACHE_HOME/dnuos).
  • Made the Makefile more consistent across platforms. This is now the recommended way to install Dnuos.
  • Fixed album and artist information not being populated for FLAC files. (Cached directories with FLAC files will be rescanned.)
  • Fixed potential Unicode error crashes with file names that aren't properly encoded with the file system's character encoding.

### Version 1.0.5 (May 5, 2008)

  • Fixed potential Unicode error crashes due to UTF-8 cache format transition.

### Version 1.0.4 (May 4, 2008)

  • Greatly improved support for file and directory names with Unicode characters on Windows. Dnuos should now be able to scan folders and open audio files with Unicode characters in their paths, and Unicode characters can now be used in command line arguments.
  • Improved cache format support between Python versions.

### Version 1.0.3 (Apr. 27, 2008)

  • Fixed a crash with malformed locale environment variables (e.g. LANG, LC_ALL, etc.)
  • Fixed incorrect output when scanning root drive folders on Windows (e.g. `C:`).

### Version 1.0.2 (Mar. 29, 2008)

  • Fixed -V/--version not working in regular output.

### Version 1.0.1 (Mar. 24, 2008)

  • Improved printing of ID3 tags with null bytes.
  • Fixed Python 2.3 compatibility.
  • Fixed possible cache-related crash on certain Mac OS X environments.

### Version 1.0 (Mar. 20, 2008)

  • Added audio metadata caching.
  • Added French translation and support for localized number formatting.
  • Added -L/--list-files for listing individual files in directories. Information about individual files isn't cached, however.
  • Added -u/--unknown-types for listing directories with unsupported audio types.
  • Implemented AAC bit rate calculation.
  • Added [V] output flag that prints encoder information.
  • Fixed handling of MP3s with VBRI headers (e.g. made by Fraunhofer).
  • Cleaned up help messages.
  • Dropped support for Python 2.2.
