beets 1.3.11

In this release, we refactored the logging system to be more flexible and more useful. There are more granular levels of verbosity, the output from plugins should be more consistent, and several kinds of logging bugs should be impossible in the future.

There are also two new plugins: one for filtering the files you import and an evolved plugin for using album art as directory thumbnails in file managers. There's a new source for album art, and the importer now records the source of match data. This is a particularly huge release---there's lots more below.

There's one big change with this release: Python 2.6 is no longer supported. You'll need Python 2.7. Please trust us when we say this let us remove a surprising number of ugly hacks throughout the code.

Major new features and bigger changes:

• There are now multiple levels of output verbosity. On the command line, you can make beets somewhat verbose with -v or very verbose with -vv. For the importer especially, this makes the first verbose mode much more manageable, while still preserving an option for overwhelmingly verbose debug output. #1244
• A new filefilter plugin lets you write regular expressions to automatically avoid importing certain files. Thanks to @mried. #1186
• A new thumbnails plugin generates cover-art thumbnails for album folders for Freedesktop.org-compliant file managers. (This replaces the freedesktop, which only worked with the Dolphin file manager.)
• replaygain: There is a new backend that uses the bs1770gain analysis tool. Thanks to @jmwatte. #1343
• A new filesize field on items indicates the number of bytes in the file. #1291
• A new searchlimit configuration option allows you to specify how many search results you wish to see when looking up releases at MusicBrainz during import. #1245
• The importer now records the data source for a match in a new flexible attribute data_source on items and albums. #1311
• The colors used in the terminal interface are now configurable via the new config option colors, nested under the option ui. (Also, the color config option has been moved from top-level to under ui. Beets will respect the old color setting, but will warn the user with a deprecation message.) #1238
• fetchart: There's a new Wikipedia image source that uses DBpedia to find albums. Thanks to Tom Jaspers. #1194
• In the config command, the output is now redacted by default. Sensitive information like passwords and API keys is not included. The new --clear option disables redaction. #1376

You should probably also know about these core changes to the way beets works:

• As mentioned above, Python 2.6 is no longer supported.
• The tracktotal attribute is now a track-level field instead of an album-level one. This field stores the total number of tracks on the album, or if the per_disc_numbering config option is set, the total number of tracks on a particular medium (i.e., disc). The field was causing problems with that per_disc_numbering mode: different discs on the same album needed different track totals. The field can now work correctly in either mode.
• To replace tracktotal as an album-level field, there is a new albumtotal computed attribute that provides the total number of tracks on the album. (The per_disc_numbering option has no influence on this field.)
• The list_format_album and list_format_item configuration keys now affect (almost) every place where objects are printed and logged. (Previously, they only controlled the list command and a few other scattered pieces.) #1269
• Relatedly, the beet program now accept top-level options --format-item and --format-album before any subcommand to control how items and albums are displayed. #1271
• list_format_album and list_format_album have respectively been renamed format_album and format_item. The old names still work but each triggers a warning message. #1271
• Path queries are automatically triggered only if the
  path targeted by the query exists. Previously, just having a slash somewhere
  in the query was enough, so beet ls AC/DC` wouldn't work to refer to the artist.

There are also lots of medium-sized features in this update:

• duplicates: The command has a new --strict option that will only report duplicates if all attributes are explicitly set. #1000
• smartplaylist: Playlist updating should now be faster: the plugin detects, for each playlist, whether it needs to be regenerated, instead of obliviously regenerating all of them. The splupdate command can now also take additional parameters that indicate the names of the playlists to regenerate.
• play: The command shows the output of the underlying player command and lets you interact with it. #1321
• The summary shown to compare duplicate albums during import now displays the old and new filesizes. #1291
• lastgenre: Add comedy, humor, and stand-up as well as a longer list of classical music genre tags to the built-in whitelist and canonicalization tree. #1206 #1239 #1240
• web: Add support for cross-origin resource sharing for more flexible in-browser clients. Thanks to Andre Miller. #1236 #1237
• plugins/mbsync: A new -f/--format option controls the output format when listing unrecognized items. The output is also now more helpful by default. #1246
• fetchart: A new option, -n, extracts the cover art of all matched albums into their respective directories. Another new flag, -a, associates the extracted files with the albums in the database. #1261
• info: A new option, -i, can display only a specified subset of properties. #1287
• The number of missing/unmatched tracks is shown during import. #1088
• permissions: The plugin now also adjusts the permissions of the directories. (Previously, it only affected files.) #1308 #1324
• ftintitle: You can now configure the format that the plugin uses to add the artist to the title. Thanks to @amishb. #1377

And many little fixes and improvements:

• replaygain: Stop applying replaygain directly to source files when using the mp3gain backend. #1316
• Path queries are case-sensitive on non-Windows OSes. #1165
• lyrics: Silence a warning about insecure requests in the new MusixMatch backend. #1204
• Fix a crash when beet is invoked without arguments. #1205 #1207
• fetchart: Do not attempt to import directories as album art. #1177 #1211
• mpdstats: Avoid double-counting some play events. #773 #1212
• Fix a crash when the importer deals with Unicode metadata in --pretend mode. #1214
• smartplaylist: Fix album_query so that individual files are added to the playlist instead of directories. #1225
• Remove the beatport plugin. Beatport_ has shut off public access to their API and denied our request for an account. We have not heard from the company since 2013, so we are assuming access will not be restored.
• Incremental imports now (once again) show a "skipped N directories" message.
• embedart: Handle errors in ImageMagick's output. #1241
• keyfinder: Parse the underlying tool's output more robustly. #1248
• embedart: We now show a comprehensible error message when beet embedart -f FILE is given a non-existent path. #1252
• Fix a crash when a file has an unrecognized image type tag. Thanks to Matthias Kiefer. #1260
• importfeeds and smartplaylist: Automatically create parent directories for playlist files (instead of crashing when the parent directory does not exist). #1266
• The write-cmd` command no longer tries to "write" non-writable fields, such as the bitrate. #1268
• The error message when MusicBrainz is not reachable on the network is now much clearer. Thanks to Tom Jaspers. #1190 #1272
• Improve error messages when parsing query strings with shlex. #1290
• embedart: Fix a crash that occured when used together with the check plugin. #1241
• scrub: Log an error instead of stopping when the beet scrub command cannot write a file. Also, avoid problems on Windows with Unicode filenames. #1297
• discogs: Handle and log more kinds of communication errors. #1299 #1305
• lastgenre: Bugs in the pylast library can no longer crash beets.
• convert: You can now configure the temporary directory for conversions. Thanks to @autochthe. #1382 #1383
• rewrite: Fix a regression that prevented the plugin's rewriting from applying to album-level fields like $albumartist. #1393
• play: The plugin now sorts items according to the configuration in album mode.
• fetchart: The name for extracted art files is taken from the art_filename configuration option. #1258
• When there's a parse error in a query (for example, when you type a malformed date in a date query), beets now stops with an error instead of silently ignoring the query component.

For developers:

• The database_change event now sends the item or album that is subject to a change.
• The OptionParser is now a CommonOptionsParser that offers facilities for adding usual options (--album, --path and --format). See add_subcommands. #1271
• The logging system in beets has been overhauled. Plugins now each have their own logger, which helps by automatically adjusting the verbosity level in import mode and by prefixing the plugin's name. Logging levels are dynamically set when a plugin is called, depending on how it is called (import stage, event or direct command). Finally, logging calls can (and should!) use modern {}-style string formatting lazily. See plugin-logging in the plugin API docs.
• A new import_task_created event lets you manipulate import tasks immediately after they are initialized. It's also possible to replace the originally created tasks by returning new ones using this event.

beets 1.3.10

This version adds a healthy helping of new features and fixes a critical MPEG-4--related bug. There are more lyrics sources, there new plugins for managing permissions and integrating with Plex, and the importer has a new --pretend flag that shows which music would be imported.

One backwards-compatibility note: the lyrics now requires the requests_ library. If you use this plugin, you will need to install the library by typing pip install requests or the equivalent for your OS.

Also, as an advance warning, this will be one of the last releases to support Python 2.6. If you have a system that cannot run Python 2.7, please consider upgrading soon.

The new features are:

• A new permissions makes it easy to fix permissions on music files as they are imported. Thanks to xsteadfastx. #1098
• A new plexupdate lets you notify a Plex server when the database changes. Thanks again to xsteadfastx. #1120
• The import-cmdcommand now has a--pretend` flag that lists the files that will be imported. Thanks to mried. #1162
• lyrics: Add Musixmatch source and introduce a new sources config option that lets you choose exactly where to look for lyrics and in which order.
• lyrics: Add Brazilian and Spanish sources to Google custom search engine.
• Add a warning when importing a directory that contains no music. #1116 #1127
• zero: Can now remove embedded images. #1129 #1100
• The config command can now be used to edit the configuration even when it has syntax errors. #1123 #1128
• lyrics: Added a new force config option. #1150

As usual, there are loads of little fixes and improvements:

• Fix a new crash with the latest version of Mutagen (1.26).
• lyrics: Avoid fetching truncated lyrics from the Google backed by merging text blocks separated by empty ` tags before scraping.
• We now print a better error message when the database file is corrupted.
• discogs: Only prompt for authentication when running the import command. #1123
• When deleting fields with the modify command, do not crash when the field cannot be removed (i.e., when it does not exist, when it is a built-in field, or when it is a computed field). #1124
• The deprecated echonest_tempo plugin has been removed. Please use the echonest instead.
• echonest: Fingerprint-based lookup has been removed in accordance with API changes. #1121
• echonest: Avoid a crash when the song has no duration information. #896
• lyrics: Avoid a crash when retrieving non-ASCII lyrics from the Google backend. #1135 #1136
• smartplaylist: Sort specifiers are now respected in queries. Thanks to djl. #1138 #1137
• ftintitle and lyrics: Featuring artists can now be detected when they use the Spanish word con. #1060 #1143
• mbcollection: Fix an "HTTP 400" error caused by a change in the MusicBrainz API. #1152
• The % and _ characters in path queries do not invoke their special SQL meaning anymore. #1146

• importadded: Now works with in-place and symlinked imports. #1170
• ftintitle: The plugin is now quiet when it runs as part of the import process. Thanks to Freso. #1176 #1172
• ftintitle: Fix weird behavior when the same artist appears twice in the artist string. Thanks to Marc Addeo. #1179 #1181
• lastgenre: Match songs more robustly when they contain dashes. Thanks to djl. #1156
• The config command can now use $EDITOR variables with arguments.

beets 1.3.9

This release adds two new standard plugins to beets: one for synchronizing Last.fm listening data and one for integrating with Linux desktops. And at long last, imports can now create symbolic links to music files instead of copying or moving them. We also gained the ability to search for album art on the iTunes Store and a new way to compute ReplayGain levels.

The major new features are:

• A new lastimport lets you download your play count data from Last.fm into a flexible attribute. Thanks to Rafael Bodill.
• A new freedesktop creates metadata files for Freedesktop.org-compliant file managers. Thanks to kerobaros. #1056, #707
• A new link option in the import section creates symbolic links during import instead of moving or copying. Thanks to Rovanion Luckey. #710, #114
• fetchart: You can now search for art on the iTunes Store. There's also a new sources config option that lets you choose exactly where to look for images and in which order.
• replaygain: A new Python Audio Tools backend was added. Thanks to Francesco Rubino. #1070
• embedart: You can now automatically check that new art looks similar to existing art---ensuring that you only get a better "version" of the art you already have. See image-similarity-check.
• ftintitle: The plugin now runs automatically on import. To disable this, unset the auto config flag.

There are also core improvements and other substantial additions:

• The media attribute is now a track-level field instead of an album-level one. This field stores the delivery mechanism for the music, so in its album-level incarnation, it could not represent heterogeneous releases---for example, an album consisting of a CD and a DVD. Now, tracks accurately indicate the media they appear on. Thanks to Heinz Wiesinger.
• Re-imports of your existing music now preserve its added date and flexible attributes. Thanks to Stig Inge Lea Bjørnsen.
• Slow queries, such as those over flexible attributes, should now be much faster when used with certain commands---notably, the play.
• bpd: Add a new configuration option for setting the default volume. Thanks to IndiGit.
• embedart: A new ifempty config option lets you only embed album art when no album art is present. Thanks to kerobaros.
• discogs: Authenticate with the Discogs server. The plugin now requires a Discogs account due to new API restrictions. Thanks to multikatt. #1027, #1040

And countless little improvements and fixes:

• Standard cover art in APEv2 metadata is now supported. Thanks to Matthias Kiefer. #1042
• convert: Avoid a crash when embedding cover art fails.
• mpdstats: Fix an error on start (introduced in the previous version). Thanks to Zach Denton.
• convert: The --yes command-line flag no longer expects an argument.
• play: Remove the temporary .m3u file after sending it to the player.
• The importer no longer tries to highlight partial differences in numeric quantities (track numbers and durations), which was often confusing.
• Date-based queries that are malformed (not parse-able) no longer crash beets and instead fail silently.
• duplicates: Emit an error when the checksum config option is set incorrectly.
• The migration from pre-1.1, non-YAML configuration files has been removed. If you need to upgrade an old config file, use an older version of beets temporarily.
• discogs: Recover from HTTP errors when communicating with the Discogs servers. Thanks to Dustin Rodriguez.
• embedart: Do not log "embedding album art into..." messages during the import process.
• Fix a crash in the autotagger when files had only whitespace in their metadata.
• play: Fix a potential crash when the command outputs special characters. #1041
• web: Queries typed into the search field are now treated as separate query components. #1045
• Date tags that use slashes instead of dashes as separators are now interpreted correctly. And WMA (ASF) files now map the comments field to the "Description" tag (in addition to "WM/Comments"). Thanks to Matthias Kiefer. #1043
• embedart: Avoid resizing the image multiple times when embedding into an album. Thanks to kerobaros. #1028, #1036
• discogs: Avoid a situation where a trailing comma could be appended to some artist names. #1049
• The output of the stats command is slightly different: the approximate size is now marked as such, and the total number of seconds only appears in exact mode.
• convert: A new copy_album_art option puts images alongside converted files. Thanks to Ángel Alonso. #1050, #1055
• There is no longer a "conflict" between two plugins that declare the same field with the same type. Thanks to Peter Schnebel. #1059 #1061
• chroma: Limit the number of releases and recordings fetched as the result of an Acoustid match to avoid extremely long processing times for very popular music. #1068
• Fix an issue where modifying an album's field without actually changing it would not update the corresponding tracks to bring differing tracks back in line with the album. #856
• echonest: When communicating with the Echo Nest servers fails repeatedly, log an error instead of exiting. #1096
• lyrics: Avoid an error when the Google source returns a result without a title. Thanks to Alberto Leal. #1097
• Importing an archive will no longer leave temporary files behind in /tmp. Thanks to multikatt. #1067, #1091

beets 1.3.8

This release has two big new chunks of functionality. Queries now support sorting and user-defined fields can now have types.

If you want to see all your songs in reverse chronological order, just type beet list year-. It couldn't be easier.

Flexible field types mean that some functionality that has previously only worked for built-in fields, like range queries, can now work with plugin- and user-defined fields too. For starters, the /plugins/echonest/ and mpdstats now mark the types of the fields they provide---so you can now say, for example, beet ls liveness:0.5..1.5 for the Echo Nest "liveness" attribute. The types makes it easy to specify field types in your config file.

One upgrade note: if you use the discogs, you will need to upgrade the Discogs client library to use this version. Just type pip install -U discogs-client.

Other new features:

• info: Target files can now be specified through library queries (in addition to filenames). The --library option prints library fields instead of tags. Multiple files can be summarized together with the new --summarize option.
• mbcollection: A new option lets you automatically update your collection on import. Thanks to Olin Gay.
• convert: A new never_convert_lossy_files option can prevent lossy transcoding. Thanks to Simon Kohlmeyer.
• convert: A new --yes command-line flag skips the confirmation.

Still more fixes and little improvements:

• Invalid state files don't crash the importer.
• lyrics: Only strip featured artists and parenthesized title suffixes if no lyrics for the original artist and title were found.
• Fix a crash when reading some files with missing tags.
• discogs: Compatibility with the new 2.0 version of the discogs_client Python library. If you were using the old version, you wil need to upgrade to the latest version of the library to use the correspondingly new version of the plugin (e.g., with pip install -U discogs-client). Thanks to Andriy Kohut.
• Fix a crash when writing files that can't be read. Thanks to Jocelyn De La Rosa.
• The stats command now counts album artists. The album count also more accurately reflects the number of albums in the database.
• convert: Avoid crashes when tags cannot be written to newly converted files.
• Formatting templates with item data no longer confusingly shows album-level data when the two are inconsistent.
• Resuming imports and beginning incremental imports should now be much faster when there is a lot of previously-imported music to skip.
• lyrics: Remove <script> tags from scraped lyrics. Thanks to Bombardment.
• play: Add a relative_to config option. Thanks to BrainDamage.
• Fix a crash when a MusicBrainz release has zero tracks.
• The --version flag now works as an alias for the version command.
• lastgenre: Remove some unhelpful genres from the default whitelist. Thanks to gwern.
• importfeeds: A new echo output mode prints files' paths to standard error. Thanks to robotanarchy.
• replaygain: Restore some error handling when mp3gain output cannot be parsed. The verbose log now contains the bad tool output in this case.
• convert: Fix filename extensions when converting automatically.
• The write plugin event allows plugins to change the tags that are written to a media file.
• zero: Do not delete database values; only media file tags are affected.

beets 1.3.7

This release of beets fixes all the bugs, and you can be confident that you will never again find any bugs in beets, ever. It also adds support for plain old AIFF files and adds three more plugins, including a nifty one that lets you measure a song's tempo by tapping out the beat on your keyboard. The importer deals more elegantly with duplicates and you can broaden your cover art search to the entire web with Google Image Search.

The big new features are:

• Support for AIFF files. Tags are stored as ID3 frames in one of the file's IFF chunks. Thanks to Evan Purkhiser for contributing support to Mutagen.
• The new importadded reads files' modification times to set their "added" date. Thanks to Stig Inge Lea Bjørnsen.
• The new bpm lets you manually measure the tempo of a playing song. Thanks to aroquen.
• The new spotify generates playlists for your Spotify account. Thanks to Olin Gay.
• A new required configuration option for the importer skips matches that are missing certain data. Thanks to oprietop.
• When the importer detects duplicates, it now shows you some details about the potentially-replaced music so you can make an informed decision. Thanks to Howard Jones.
• fetchart: You can now optionally search for cover art on Google Image Search. Thanks to Lemutar.
• A new asciify-paths configuration option replaces all non-ASCII characters in paths.

And the multitude of little improvements and fixes:

• Compatibility with the latest version of Mutagen, 1.23.
• web: Lyrics now display readably with correct line breaks. Also, the detail view scrolls to reveal all of the lyrics. Thanks to Meet Udeshi.
• play: The command config option can now contain arguments (rather than just an executable). Thanks to Alessandro Ghedini.
• Fix an error when using the modify command to remove a flexible attribute. Thanks to Pierre Rust.
• info: The command now shows audio properties (e.g., bitrate) in addition to metadata. Thanks Alessandro Ghedini.
• Avoid a crash on Windows when writing to files with special characters in their names.
• play: Playing albums now generates filenames by default (as opposed to directories) for better compatibility. The use_folders option restores the old behavior. Thanks to Lucas Duailibe.
• Fix an error when importing an empty directory with the --flat option.
• mpdstats: The last song in a playlist is now correctly counted as played. Thanks to Johann Klähn.
• zero: Prevent accidental nulling of dangerous fields (IDs and paths). Thanks to brunal.
• The remove command now shows the paths of files that will be deleted. Thanks again to brunal.
• Don't display changes for fields that are not in the restricted field set. This fixes write showing changes for fields that are not written to the file.
• The write command avoids displaying the item name if there are no changes for it.
• When using both the convert and the scrub, avoid scrubbing the source file of conversions. (Fix a regression introduced in the previous release.)
• replaygain: Logging is now quieter during import. Thanks to Yevgeny Bezman.
• fetchart: When loading art from the filesystem, we now prioritize covers with more keywords in them. This means that cover-front.jpg will now be taken before cover-back.jpg because it contains two keywords rather than one. Thanks to Fabrice Laporte.
• lastgenre: Remove duplicates from canonicalized genre lists. Thanks again to Fabrice Laporte.
• The importer now records its progress when skipping albums. This means that incremental imports will no longer try to import albums again after you've chosen to skip them, and erroneous invitations to resume "interrupted" imports should be reduced. Thanks to jcassette.
• bucket: You can now customize the definition of alphanumeric "ranges" using regular expressions. And the heuristic for detecting years has been improved. Thanks to sotho.
• Already-imported singleton tracks are skipped when resuming an import.
• chroma: A new auto configuration option disables fingerprinting on import. Thanks to ddettrittus.
• convert: A new --format option to can select the transcoding preset from the command-line.
• convert: Transcoding presets can now omit their filename extensions (extensions default to the name of the preset).
• convert: A new --pretend option lets you preview the commands the plugin will execute without actually taking any action. Thanks to Dietrich Daroch.
• Fix a crash when a float-valued tag field only contained a + or - character.
• Fixed a regression in the core that caused the scrub not to work in auto mode. Thanks to Harry Khanna.
• The write command now has a --force flag. Thanks again to Harry Khanna.
• mbsync: Track alignment now works with albums that have multiple copies of the same recording. Thanks to Rui Gonçalves.

beets 1.3.6

This is primarily a bugfix release, but it also brings two new plugins: one for playing music in desktop players and another for organizing your directories into "buckets." It also brings huge performance optimizations to queries—your beet ls commands will now go much faster.

New features:

• The new play lets you start your desktop music player with the songs that match a query. Thanks to David Hamp-Gonsalves.
• The new bucket provides a %bucket{} function for path formatting to generate folder names representing ranges of years or initial letter. Thanks to Fabrice Laporte.
• Item and album queries are much faster.
• ftintitle: A new option lets you remove featured artists entirely instead of moving them to the title. Thanks to SUTJael.

And those all-important bug fixes:

• mbsync: Fix a regression in 1.3.5 that broke the plugin entirely.
• Shell completion now searches more common paths for its bash_completion dependency.
• Fix encoding-related logging errors in convert and replaygain.
• replaygain: Suppress a deprecation warning emitted by later versions of PyGI.
• Fix a crash when reading files whose iTunes SoundCheck tags contain non-ASCII characters.
• The %if{} template function now appropriately interprets the condition as false when it contains the string "false". Thanks to Ayberk Yilmaz.
• convert: Fix conversion for files that include a video stream by ignoring it. Thanks to brunal.
• fetchart: Log an error instead of crashing when tag manipulation fails.
• convert: Log an error instead of crashing when embedding album art fails.
• convert: Embed cover art into converted files. Previously they were embedded into the source files.
• New plugin event: before_item_moved. Thanks to Robert Speicher.

beets 1.3.5

This is a short-term release that adds some great new stuff to beets. There's support for tracking and calculating musical keys, the ReplayGain plugin was expanded to work with more music formats via GStreamer, we can now import directly from compressed archives, and the lyrics plugin is more robust.

One note for upgraders and packagers: this version of beets has a new dependency in enum34, which is a backport of the new enum standard library module.

The major new features are:

• Beets can now import zip, tar and rar archives. Just type beet import music.zip to have beets transparently extract the files to import.
• replaygain: Added support for calculating ReplayGain values with GStreamer as well the mp3gain program. This enables ReplayGain calculation for any audio format. Thanks to Yevgeny Bezman.
• lyrics: Lyrics should now be found for more songs. Searching is now sensitive to featured artists and parenthesized title suffixes. When a song has multiple titles, lyrics from all the named songs are now concatenated. Thanks to Fabrice Laporte and Paul Phillips.

In particular, a full complement of features for supporting musical keys are new in this release:

• A new initial_key field is available in the database and files' tags. You can set the field manually using a command like beet modify initial_key=Am.
• The echonest plugin sets the initial_key field if the data is available.
• A new keyfinder runs a command-line tool to get the key from audio data and store it in the initial_key field.

There are also many bug fixes and little enhancements:

• echonest: Truncate files larger than 50MB before uploading for analysis.
• fetchart: Fix a crash when the server does not specify a content type. Thanks to Lee Reinhardt.
• convert: The --keep-new flag now works correctly and the library includes the converted item.
• The importer now logs a message instead of crashing when errors occur while opening the files to be imported.
• embedart: Better error messages in exceptional conditions.
• Silenced some confusing error messages when searching for a non-MusicBrainz ID. Using an invalid ID (of any kind—Discogs IDs can be used there too) at the "Enter ID:" importer prompt now just silently returns no results. More info is in the verbose logs.
• mbsync: Fix application of album-level metadata. Due to a regression a few releases ago, only track-level metadata was being updated.
• On Windows, paths on network shares (UNC paths) no longer cause "invalid filename" errors.
• replaygain: Fix crashes when attempting to log errors.
• The modify-cmd command can now accept query arguments that contain = signs. An argument is considered a query part when a : appears before any =s. Thanks to mook.

beets 1.3.4

This release brings a hodgepodge of medium-sized conveniences to beets. A new config command manages your configuration, we now have bash completion, and the modify command can delete attributes. There are also some significant performance optimizations to the autotagger's matching logic.

One note for upgraders: if you use the fetchart plugin, it has a new dependency, the requests module.

New stuff:

• Added a config command to manage your configuration. It can show you what you currently have in your config file, point you at where the file should be, or launch your text editor to let you modify the file. Thanks to geigerzaehler.
• Beets now ships with a shell command completion script! See completion. Thanks to geigerzaehler.
• The modify command now allows removing flexible attributes. For example, beet modify artist:beatles oldies! deletes the oldies attribute from matching items. Thanks to brilnius.
• Internally, beets has laid the groundwork for supporting multi-valued fields. Thanks to geigerzaehler.
• The importer interface now shows the URL for MusicBrainz matches. Thanks to johtso.
• smartplaylist: Playlists can now be generated from multiple queries (combined with "or" logic). Album-level queries are also now possible and automatic playlist regeneration can now be disabled. Thanks to brilnius.
• echonest: Echo Nest similarity now weights the tempo in better proportion to other metrics. Also, options were added to specify custom thresholds and output formats. Thanks to Adam M.
• Added the after_write plugin event.
• lastgenre: Separator in genre lists can now be configured. Thanks to brilnius.
• We now only use "primary" aliases for artist names from MusicBrainz. This eliminates some strange naming that could occur when the languages config option was set. Thanks to Filipe Fortes.
• The performance of the autotagger's matching mechanism is vastly improved. This should be noticeable when matching against very large releases such as box sets.
• The import command can now accept individual files as arguments even in non-singleton mode. Files are imported as one-track albums.

Fixes:

• Error messages involving paths no longer escape non-ASCII characters (for legibility).
• Fixed a regression that made it impossible to use the modify command to add new flexible fields. Thanks to brilnius.
• echonest: Avoid crashing when the audio analysis fails. Thanks to Pedro Silva.
• duplicates: Fix checksumming command execution for files with quotation marks in their names. Thanks again to Pedro Silva.
• Fix a crash when importing with both of the group_albums and incremental options enabled. Thanks to geigerzaehler.
• Give a sensible error message when BEETSDIR points to a file. Thanks again to geigerzaehler.
• Fix a crash when reading WMA files whose boolean-valued fields contain strings. Thanks to johtso.
• fetchart: The plugin now sends "beets" as the User-Agent when making scraping requests. This helps resolve some blocked requests. The plugin now also depends on the requests Python library.
• The write command now only shows the changes to fields that will actually be written to a file.
• duplicates: Spurious reports are now avoided for tracks with missing values (e.g., no MBIDs). Thanks to Pedro Silva.
• The default replace sanitation options now remove leading whitespace by default. Thanks to brilnius.
• importfeeds: Fix crash when importing albums containing / with the m3u_multi format.
• Avoid crashing on Mutagen bugs while writing files' tags.
• convert: Display a useful error message when the FFmpeg executable can't be found.

beets 1.3.3

Version 1.3.3 brings a bunch changes to how item and album fields work internally. Along with laying the groundwork for some great things in the future, this brings a number of improvements to how you interact with beets. Here's what's new with fields in particular:

• Plugin-provided fields can now be used in queries. For example, if you use the inline plugin to define a field called era, you can now filter your library based on that field by typing something like beet list era:goldenage.
• Album-level flexible attributes and plugin-provided attributes can now be used in path formats (and other item-level templates).
• Date-based queries are now possible. Try getting every track you added in February 2014 with beet ls added:2014-02 or in the whole decade with added:2010... Thanks to Stig Inge Lea Bjørnsen.
• The modify-cmd command is now better at parsing and formatting fields. You can assign to boolean fields like comp, for example, using either the words "true" or "false" or the numerals 1 and 0. Any boolean-esque value is normalized to a real boolean. The update-cmd and write-cmd commands also got smarter at formatting and colorizing changes.

For developers, the short version of the story is that Item and Album objects provide uniform access across fixed, flexible, and computed attributes. You can write item.foo to access the foo field without worrying about where the data comes from.

Unrelated new stuff:

• The importer has a new interactive option (G for "Group albums"), command-line flag (--group-albums), and config option (group_albums) that lets you split apart albums that are mixed together in a single directory. Thanks to geigerzaehler.
• A new --config command-line option lets you specify an additional configuration file. This option combines config settings with your default config file. (As part of this change, the BEETSDIR environment variable no longer combines---it replaces your default config file.) Thanks again to geigerzaehler.
• ihate: The plugin's configuration interface was overhauled. Its configuration is now much simpler---it uses beets queries instead of an ad-hoc per-field configuration. This is backwards-incompatible---if you use this plugin, you will need to update your configuration. Thanks to BrainDamage.

Other little fixes:

• echonest: Tempo (BPM) is now always stored as an integer. Thanks to Heinz Wiesinger.
• Fix Python 2.6 compatibility in some logging statements in chroma and lastgenre.
• Prevent some crashes when things go really wrong when writing file metadata at the end of the import process.
• New plugin events: item_removed (thanks to Romuald Conty) and item_copied (thanks to Stig Inge Lea Bjørnsen).
• The pluginpath config option can now point to the directory containing plugin code. (Previously, it awkwardly needed to point at a directory containing a beetsplug directory, which would then contain your code. This is preserved as an option for backwards compatibility.) This change should also work around a long-standing issue when using pluginpath when beets is installed using pip. Many thanks to geigerzaehler.
• web: The /item/ and /album/ API endpoints now produce full details about albums and items, not just lists of IDs. Thanks to geigerzaehler.
• Fix a potential crash when using image resizing with the fetchart or embedart without ImageMagick installed.
• Also, when invoking convert for image resizing fails, we now log an error instead of crashing.
• fetchart: The beet fetchart command can now associate local images with albums (unless --force is provided). Thanks to brilnius.
• fetchart: Command output is now colorized. Thanks again to brilnius.
• The modify-cmd command avoids writing files and committing to the database when nothing has changed. Thanks once more to brilnius.
• The importer now uses the album artist field when guessing existing metadata for albums (rather than just the track artist field). Thanks to geigerzaehler.
• fromfilename: Fix a crash when a filename contained only a track number (e.g., 02.mp3).
• convert: Transcoding should now work on Windows.
• duplicates: The move and copy destination arguments are now treated as directories. Thanks to Pedro Silva.
• The modify-cmd command now skips confirmation and prints a message if no changes are necessary. Thanks to brilnius.
• fetchart: When using the remote_priority config option, local image files are no longer completely ignored.
• echonest: Fix an issue causing the plugin to appear twice in the output of the beet version command.
• lastgenre: Fix an occasional crash when no tag weight was returned by Last.fm.
• mpdstats: Restore the last_played field. Thanks to Johann Klähn.
• The modify-cmd command's output now clearly shows when a file has been deleted.
• Album art in files with Vorbis Comments is now marked with the "front cover" type. Thanks to Jason Lefley.

beets 1.3.2

This update brings new plugins for fetching acoustic metrics and listening statistics, many more options for the duplicate detection plugin, and flexible options for fetching multiple genres.

The "core" of beets gained a new built-in command: beet write updates the metadata tags for files, bringing them back into sync with your database. Thanks to Heinz Wiesinger.

We added some plugins and overhauled some existing ones:

• The new echonest plugin can fetch a wide range of acoustic attributes from The Echo Nest, including the "speechiness" and "liveness" of each track. The new plugin supersedes an older version (echonest_tempo) that only fetched the BPM field. Thanks to Pedro Silva and Peter Schnebel.
• The duplicates plugin got a number of new features, thanks to Pedro Silva:
  • The keys option lets you specify the fields used detect duplicates.
  • You can now use checksumming (via an external command) to find duplicates instead of metadata via the checksum option.
  • The plugin can perform actions on the duplicates it find. The new copy, move, delete, delete_file, and tag options perform those actions.
• The new mpdstats plugin collects statistics about your listening habits from MPD. Thanks to Peter Schnebel and Johann Klähn.
• lastgenre: The new multiple option has been replaced with the count option, which lets you limit the number of genres added to your music. (No more thousand-character genre fields!) Also, the min_weight field filters out nonsense tags to make your genres more relevant. Thanks to Peter Schnebel and rashley60.
• lyrics: A new --force option optionally re-downloads lyrics even when files already have them. Thanks to Bitdemon.

As usual, there are also innumerable little fixes and improvements:

• When writing ID3 tags for ReplayGain normalization, tags are written with both upper-case and lower-case TXXX frame descriptions. Previous versions of beets used only the upper-case style, which seems to be more standard, but some players (namely, Quod Libet and foobar2000) seem to only use lower-case names.
• missing: Avoid a possible error when an album's tracktotal field is missing.
• ftintitle: Fix an error when the sort artist is missing.
• echonest_tempo: The plugin should now match songs more reliably (i.e., fewer "no tempo found" messages). Thanks to Peter Schnebel.
• convert: Fix an "Item has no library" error when using the auto config option.
• convert: Fix an issue where files of the wrong format would have their transcoding skipped (and files with the right format would be needlessly transcoded). Thanks to Jakob Schnitzer.
• Fix an issue that caused the id3v23 option to work only occasionally.
• Also fix using id3v23 in conjunction with the scrub and embedart plugins. Thanks to Chris Cogburn.
• ihate: Fix an error when importing singletons. Thanks to Mathijs de Bruin.
• The clutter option can now be a whitespace-separated list in addition to a YAML list.
• Values for the replace option can now be empty (i.e., null is equivalent to the empty string).
• lastgenre: Fix a conflict between canonicalization and multiple genres.
• When a match has a year but not a month or day, the autotagger now "zeros out" the month and day fields after applying the year.
• For plugin developers: added an optparse callback utility function for performing actions based on arguments. Thanks to Pedro Silva.
• scrub: Fix scrubbing of MPEG-4 files. Thanks to Yevgeny Bezman.
