xklb 2.2.112

xk library

library (media toolkit)

A wise philosopher once told me: "the future is autotainment".

Manage and curate large media libraries. An index for your archive. Primary usage is local filesystem but also supports some virtual constructs like tracking online video playlists (eg. YouTube subscriptions) and scheduling browser tabs.

Install

Linux recommended but Windows setup instructions available.

pip install xklb

Should also work on Mac OS.

External dependencies

Required: ffmpeg

Some features work better with: mpv, firefox, fish

Getting started

Local media

1. Extract Metadata

For thirty terabytes of video the initial scan takes about four hours to complete. After that, subsequent scans of the path (or any subpaths) are much quicker--only new files will be read by ffprobe.

library fsadd tv.db ./video/folder/

2. Watch / Listen from local files

library watch tv.db                           # the default post-action is to do nothing
library watch tv.db --post-action delete      # delete file after playing
library listen finalists.db -k ask_keep       # ask whether to keep file after playing

To stop playing press Ctrl+C in either the terminal or mpv

Online media

1. Download Metadata

Download playlist and channel metadata. Break free of the YouTube algo~

library tubeadd educational.db https://www.youtube.com/c/BranchEducation/videos

And you can always add more later--even from different websites.

library tubeadd maker.db https://vimeo.com/terburg

To prevent mistakes the default configuration is to download metadata for only the most recent 20,000 videos per playlist/channel.

library tubeadd maker.db --extractor-config playlistend=1000

Be aware that there are some YouTube Channels which have many items--for example the TEDx channel has about 180,000 videos. Some channels even have upwards of two million videos. More than you could likely watch in one sitting--maybe even one lifetime. On a high-speed connection (>500 Mbps), it can take up to five hours to download the metadata for 180,000 videos.

TIP! If you often copy and paste many URLs you can paste line-delimited text as arguments via a subshell. For example, in fish shell with cb:

library tubeadd my.db (cb)

Or in BASH:

library tubeadd my.db $(xclip -selection c)

1a. Get new videos for saved playlists

Tubeupdate will go through the list of added playlists and fetch metadata for any videos not previously seen.

library tubeupdate tube.db

2. Watch / Listen from websites

library watch maker.db

To stop playing press Ctrl+C in either the terminal or mpv

Tabs

Visit websites on a schedule

tabs is a way to organize your visits to URLs that you want to remember every once in a while.

The main benefit of tabs is that you can have a large amount of tabs saved (say 500 monthly tabs) and only the smallest amount of tabs to satisfy that goal (500/30) tabs will open each day. 17 tabs per day seems manageable--500 all at once does not.

The use-case of tabs are websites that you know are going to change: subreddits, games, or tools that you want to use for a few minutes daily, weekly, monthly, quarterly, or yearly.

1. Add your websites

library tabsadd tabs.db --frequency monthly --category fun \
    https://old.reddit.com/r/Showerthoughts/top/?sort=top&t=month \
    https://old.reddit.com/r/RedditDayOf/top/?sort=top&t=month

2. Add library tabs to cron

library tabs is meant to run once per day. Here is how you would configure it with crontab:

45 9 * * * DISPLAY=:0 library tabs /home/my/tabs.db

Or with systemd:

tee ~/.config/systemd/user/tabs.service
[Unit]
Description=xklb daily browser tabs

[Service]
Type=simple
RemainAfterExit=no
Environment="DISPLAY=:0"
ExecStart="/usr/bin/fish" "-c" "lb tabs /home/xk/lb/tabs.db"

tee ~/.config/systemd/user/tabs.timer
[Unit]
Description=xklb daily browser tabs timer

[Timer]
Persistent=yes
OnCalendar=*-*-* 9:58

[Install]
WantedBy=timers.target

systemctl --user daemon-reload
systemctl --user enable --now tabs.service

You can also invoke tabs manually:

library tabs tabs.db -L 1  # open one tab

Incremental surfing. 📈🏄 totally rad!

Find large folders

Curate with library bigdirs

If you are looking for candidate folders for curation (ie. you need space but don't want to buy another hard drive). The bigdirs subcommand was written for that purpose:

$ library bigdirs fs/d.db

You may filter by folder depth (similar to QDirStat or WizTree)

$ library bigdirs --depth=3 audio.db

There is also an flag to prioritize folders which have many files which have been deleted (for example you delete songs you don't like--now you can see who wrote those songs and delete all their other songs...)

$ library bigdirs --sort-by deleted audio.db

Recently, this functionality has also been integrated into watch/listen subcommands so you could just do this:

$ library watch --big-dirs ./my.db
$ lb wt -B  # shorthand equivalent

Pipe to mnamer

Rename poorly named files

pip install mnamer
mnamer --movie-directory ~/d/70_Now_Watching/ --episode-directory ~/d/70_Now_Watching/ \
    --no-overwrite -b (library watch -p fd -s 'path : McCloud')
library fsadd ~/d/70_Now_Watching/

Music alarm clock

via termux crontab

Wake up to your own music

30 7 * * * library listen ./audio.db

Wake up to your own music only when you are not home (computer on local IP)

30 7 * * * timeout 0.4 nc -z 192.168.1.12 22 || library listen --random

Wake up to your own music on your Chromecast speaker group only when you are home

30 7 * * * ssh 192.168.1.12 library listen --cast --cast-to "Bedroom pair"

Pipe to lowcharts

$ library watch -p f -col time_created | lowcharts timehist -w 80

BTW, for some cols like time_deleted you'll need to specify a where clause so they aren't filtered out:

$ library watch -p f -col time_deleted -w time_deleted'>'0 | lowcharts timehist -w 80

Pipe to rsync

Move files to your phone via syncthing

I used to use rsync to move files because I want deletions to stick. I now use library relmv. But this is still a good rsync example:

function mrmusic
    rsync -a --remove-source-files --files-from=(
        library lt ~/lb/audio.db -s /mnt/d/80_Now_Listening/ -p f \
        --moved /mnt/d/80_Now_Listening/ /mnt/d/ | psub
    ) /mnt/d/80_Now_Listening/ /mnt/d/

    rsync -a --remove-source-files --files-from=(
        library lt ~/lb/audio.db -w play_count=0 -u random -L 1200 -p f \
        --moved /mnt/d/ /mnt/d/80_Now_Listening/ | psub
    ) /mnt/d/ /mnt/d/80_Now_Listening/
end

Backfill

Backfill reddit databases with pushshift data

https://github.com/chapmanjacobd/reddit_mining/

for reddit_db in ~/lb/reddit/*.db
    set subreddits (sqlite-utils $reddit_db 'select path from playlists' --tsv --no-headers | grep old.reddit.com | sed 's|https://old.reddit.com/r/\(.*\)/|\1|' | sed 's|https://old.reddit.com/user/\(.*\)/|u_\1|' | tr -d "\r")

    ~/github/xk/reddit_mining/links/
    for subreddit in $subreddits
        if not test -e "$subreddit.csv"
            echo "octosql -o csv \"select path,score,'https://old.reddit.com/r/$subreddit/' as playlist_path from `../reddit_links.parquet` where lower(playlist_path) = '$subreddit' order by score desc \" > $subreddit.csv"
        end
    end | parallel -j8

    for subreddit in $subreddits
        sqlite-utils upsert --pk path --alter --csv --detect-types $reddit_db media $subreddit.csv
    end

    library tubeadd --safe --ignore-errors --force $reddit_db (sqlite-utils --raw-lines $reddit_db 'select path from media')
end

Datasette

pip install datasette
datasette tv.db

Usage

Add local media (fsadd)

$ library fsadd -h
usage: library fsadd [(--video) | --audio | --image |  --text | --filesystem] DATABASE PATHS ...

The default database type is video:
    library fsadd tv.db ./tv/
    library fsadd --video tv.db ./tv/  # equivalent

You can also create audio databases. Both audio and video use ffmpeg to read metadata:
    library fsadd --audio audio.db ./music/

Image uses ExifTool:
    library fsadd --image image.db ./photos/

Text will try to read files and save the contents into a searchable database:
    library fsadd --text text.db ./documents_and_books/

Create a text database and scan with OCR and speech-recognition:
    library fsadd --text --ocr --speech-recognition ocr.db ./receipts_and_messages/

Create a video database and read internal/external subtitle files into a searchable database:
    library fsadd --scan-subtitles tv.search.db ./tv/ ./movies/

Decode media to check for corruption (slow):
    library fsadd --check-corrupt 100 tv.db ./tv/  # scan through 100 percent of each file to evaluate how corrupt it is (very slow)
    library fsadd --check-corrupt   1 tv.db ./tv/  # scan through 1 percent of each file to evaluate how corrupt it is (takes about one second per file)
    library fsadd --check-corrupt   5 tv.db ./tv/  # scan through 5 percent of each file to evaluate how corrupt it is (takes about ten seconds per file)

    library fsadd --check-corrupt   5 --delete-corrupt 30 tv.db ./tv/  # scan 5 percent of each file to evaluate how corrupt it is, if 30 percent or more of those checks fail then the file is deleted

    nb: the behavior of delete-corrupt changes between full and partial scan
    library fsadd --check-corrupt  99 --delete-corrupt  1 tv.db ./tv/  # partial scan 99 percent of each file to evaluate how corrupt it is, if 1 percent or more of those checks fail then the file is deleted
    library fsadd --check-corrupt 100 --delete-corrupt  1 tv.db ./tv/  # full scan each file to evaluate how corrupt it is, if there is _any_ corruption then the file is deleted

Normally only relevant filetypes are included. You can scan all files with this flag:
    library fsadd --scan-all-files mixed.db ./tv-and-maybe-audio-only-files/
    # I use that with this to keep my folders organized:
    library watch -w 'video_count=0 and audio_count>=1' -pf mixed.db | parallel mv {} ~/d/82_Audiobooks/

Remove path roots with --force
    library fsadd audio.db /mnt/d/Youtube/
    [/mnt/d/Youtube] Path does not exist

    library fsadd --force audio.db /mnt/d/Youtube/
    [/mnt/d/Youtube] Path does not exist
    [/mnt/d/Youtube] Building file list...
    [/mnt/d/Youtube] Marking 28932 orphaned metadata records as deleted

Add online media (tubeadd)

$ library tubeadd -h
usage: library tubeadd [--safe] [--extra] [--subs] [--auto-subs] DATABASE URLS ...

Create a dl database / add links to an existing database

    library tubeadd dl.db https://www.youdl.com/c/BranchEducation/videos

Add links from a line-delimited file

    cat ./my_yt_subscriptions.txt | library tubeadd reddit.db -

Add metadata to links already in a database table

    library tubeadd --force reddit.db (sqlite-utils --raw-lines reddit.db 'select path from media')

Files will be saved to <download prefix>/<extractor>/

    For example:
    library tubeadd -c Cool ...
    library download D:\'My Documents'\ ...
    Media will be downloaded to 'D:\My Documents\Cool\'

Fetch extra metadata:

    By default tubeadd will quickly add media at the expense of less metadata.
    If you plan on using `library download` then it doesn't make sense to use `--extra`.
    Downloading will add the extra metadata automatically to the database.
    You can always fetch more metadata later via tubeupdate:
    library tubeupdate tw.db --extra

Add reddit media (redditadd)

$ library redditadd -h
usage: library redditadd [--lookback N_DAYS] [--praw-site bot1] DATABASE URLS ...

Fetch data for redditors and reddits:

    library redditadd interesting.db https://old.reddit.com/r/coolgithubprojects/ https://old.reddit.com/user/Diastro

If you have a file with a list of subreddits you can do this:

    library redditadd 96_Weird_History.db --subreddits (cat ~/mc/96_Weird_History-reddit.txt)

Likewise for redditors:

    library redditadd shadow_banned.db --redditors (cat ~/mc/shadow_banned.txt)

Note that reddit's API is limited to 1000 posts and it usually doesn't go back very far historically.
Also, it may be the case that reddit's API (praw) will stop working in the near future. For both of these problems
my suggestion is to use pushshift data.
You can find more info here: https://github.com/chapmanjacobd/reddit_mining#how-was-this-made

Backup tildes comments and topics

$ library tildes -h
usage: library tildes DATABASE USER

Backup tildes.net user comments and topics

    library tildes tildes.net.db xk3

Without cookies you are limited to the first page. You can use cookies like this:
    https://github.com/rotemdan/ExportCookies
    library tildes tildes.net.db xk3 --cookies ~/Downloads/cookies-tildes-net.txt

Backup substack articles

$ library substack -h
usage: library substack DATABASE PATH ...

Backup substack articles

Create / Update a Hacker News database (hnadd)

$ library hnadd -h
usage: library hnadd [--oldest] DATABASE

Fetch latest stories first:

    library hnadd hn.db -v
    Fetching 154873 items (33212696 to 33367569)
    Saving comment 33367568
    Saving comment 33367543
    Saving comment 33367564
    ...

Fetch oldest stories first:

    library hnadd --oldest hn.db

Add tabs (tabsadd)

$ library tabsadd -h
usage: library tabsadd [--frequency daily weekly (monthly) quarterly yearly] [--no-sanitize] DATABASE URLS ...

Adding one URL:

    library tabsadd -f daily tabs.db https://wiby.me/surprise/

    Depending on your shell you may need to escape the URL (add quotes)

    If you use Fish shell know that you can enable features to make pasting easier:
        set -U fish_features stderr-nocaret qmark-noglob regex-easyesc ampersand-nobg-in-token

    Also I recommend turning Ctrl+Backspace into a super-backspace for repeating similar commands with long args:
        echo 'bind \b backward-kill-bigword' >> ~/.config/fish/config.fish

Importing from a line-delimitated file:

    library tabsadd -f yearly -c reddit tabs.db (cat ~/mc/yearly-subreddit.cron)

Watch / Listen

$ library watch -h
usage: library watch DATABASE [optional args]

Control playback:
    To stop playback press Ctrl-C in either the terminal or mpv

    Create global shortcuts in your desktop environment by sending commands to mpv_socket:
    echo 'playlist-next force' | socat - /tmp/mpv_socket

Override the default player (mpv):
    library does a lot of things to try to automatically use your preferred media player
    but if it doesn't guess right you can make it explicit:
    library watch --player "vlc --vlc-opts"

Cast to chromecast groups:
    library watch --cast --cast-to "Office pair"
    library watch -ct "Office pair"  # equivalent
    If you don't know the exact name of your chromecast group run `catt scan`

Play media in order (similarly named episodes):
    library watch --play-in-order
    There are multiple strictness levels of --play-in-order:
    library watch -O    # equivalent
    library watch -OO   # above, plus ignores most filters
    library watch -OOO  # above, plus ignores fts and (include/exclude) filter during ordinal search
    library watch -OOOO # above, plus starts search with parent folder

    If searching by a specific subpath it may be preferable to just sort by path instead
    library watch d/planet.earth.2024/ -u path

    library watch --related  # Similar to -O but uses fts to find similar content
    library watch -R         # equivalent
    library watch -RR        # above, plus ignores most filters

    library watch --cluster  # cluster-sort to put similar-named paths closer together
    library watch -C         # equivalent

    library watch --big-dirs # Recommended to use with --duration or --depth filters; see `lb big-dirs -h` for more info
    library watch -B         # equivalent

    All of these options can be used together but it will be a bit slow and the results might be mid-tier
    as multiple different algorithms create a muddied signal (too many cooks in the kitchen):
    library watch -RRCOO

Filter media by file siblings of parent directory:
    library watch --sibling   # only include files which have more than or equal to one sibling
    library watch --solo      # only include files which are alone by themselves

    `--sibling` is just a shortcut for `--lower 2`; `--solo` is `--upper 1`
    library watch --sibling --solo      # you will always get zero records here
    library watch --lower 2 --upper 1   # equivalent

    You can be more specific via the `--upper` and `--lower` flags
    library watch --lower 3   # only include files which have three or more siblings
    library watch --upper 3   # only include files which have fewer than three siblings
    library watch --lower 3 --upper 3   # only include files which are three siblings inclusive
    library watch --lower 12 --upper 25 -OOO  # on my machine this launches My Mister 2018

Play recent partially-watched videos (requires mpv history):
    library watch --partial       # play newest first

    library watch --partial old   # play oldest first
    library watch -P o            # equivalent

    library watch -P p            # sort by percent remaining
    library watch -P t            # sort by time remaining
    library watch -P s            # skip partially watched (only show unseen)

    The default time used is "last-viewed" (ie. the most recent time you closed the video)
    If you want to use the "first-viewed" time (ie. the very first time you opened the video)
    library watch -P f            # use watch_later file creation time instead of modified time

    You can combine most of these options, though some will be overridden by others.
    library watch -P fo           # this means "show the oldest videos using the time I first opened them"
    library watch -P pt           # weighted remaining (percent * time remaining)

Print instead of play:
    library watch --print --limit 10  # print the next 10 files
    library watch -p -L 10  # print the next 10 files
    library watch -p  # this will print _all_ the media. be cautious about `-p` on an unfiltered set

    Printing modes
    library watch -p    # print as a table
    library watch -p a  # print an aggregate report
    library watch -p b  # print a bigdirs report (see library bigdirs -h for more info)
    library watch -p f  # print fields (defaults to path; use --cols to change)
                           # -- useful for piping paths to utilities like xargs or GNU Parallel

    library watch -p d  # mark deleted
    library watch -p w  # mark watched

    Some printing modes can be combined
    library watch -p df  # print files for piping into another program and mark them as deleted within the db
    library watch -p bf  # print fields from bigdirs report

    Check if you have downloaded something before
    library watch -u duration -p -s 'title'

Set the play queue size:
    By default the play queue is 120--long enough that you likely have not noticed
    but short enough that the program is snappy.

    If you want everything in your play queue you can use the aid of infinity.
    Pick your poison (these all do effectively the same thing):
    library watch -L inf
    library watch -l inf
    library watch --queue inf
    library watch -L 99999999999999999999999

    You may also want to restrict the play queue.
    For example, when you only want 1000 random files:
    library watch -u random -L 1000

Offset the play queue:
    You can also offset the queue. For example if you want to skip one or ten media:
    library watch --skip 10        # offset ten from the top of an ordered query

Repeat
    library watch                  # listen to 120 random songs (DEFAULT_PLAY_QUEUE)
    library watch --limit 5        # listen to FIVE songs
    library watch -l inf -u random # listen to random songs indefinitely
    library watch -s infinite      # listen to songs from the band infinite

Constrain media by search:
    Audio files have many tags to readily search through so metadata like artist,
    album, and even mood are included in search.
    Video files have less consistent metadata and so only paths are included in search.
    library watch --include happy  # only matches will be included
    library watch -s happy         # equivalent
    library watch --exclude sad    # matches will be excluded
    library watch -E sad           # equivalent

    Search only the path column
    library watch -O -s 'path : mad max'
    library watch -O -s 'path : "mad max"' # add "quotes" to be more strict

    Double spaces are parsed as one space
    library watch -s '  ost'        # will match OST and not ghost
    library watch -s toy story      # will match '/folder/toy/something/story.mp3'
    library watch -s 'toy  story'   # will match more strictly '/folder/toy story.mp3'

    You can search without -s but it must directly follow the database due to how argparse works
    library watch my.db searching for something

Constrain media by arbitrary SQL expressions:
    library watch --where audio_count = 2  # media which have two audio tracks
    library watch -w "language = 'eng'"    # media which have an English language tag
                                                (this could be audio _or_ subtitle)
    library watch -w subtitle_count=0      # media that doesn't have subtitles

Constrain media to duration (in minutes):
    library watch --duration 20
    library watch -d 6  # 6 mins ±10 percent (ie. between 5 and 7 mins)
    library watch -d-6  # less than 6 mins
    library watch -d+6  # more than 6 mins

    Duration can be specified multiple times:
    library watch -d+5 -d-7  # should be similar to -d 6

    If you want exact time use `where`
    library watch --where 'duration=6*60'

Constrain media to file size (in megabytes):
    library watch --size 20
    library watch -S 6  # 6 MB ±10 percent (ie. between 5 and 7 MB)
    library watch -S-6  # less than 6 MB
    library watch -S+6  # more than 6 MB

Constrain media by time_created / time_last_played / time_deleted / time_modified:
    library watch --created-within '3 days'
    library watch --created-before '3 years'

Constrain media by throughput:
    Bitrate information is not explicitly saved.
    You can use file size and duration as a proxy for throughput:
    library watch -w 'size/duration<50000'

Constrain media to portrait orientation video:
    library watch --portrait
    library watch -w 'width<height' # equivalent

Constrain media to duration of videos which match any size constraints:
    library watch --duration-from-size +700 -u 'duration desc, size desc'

Constrain media to online-media or local-media:
    Not to be confused with only local-media which is not "offline" (ie. one HDD disconnected)
    library watch --online-media-only
    library watch --online-media-only -i  # and ignore playback errors (ie. YouTube video deleted)
    library watch --local-media-only

Specify media play order:
    library watch --sort duration   # play shortest media first
    library watch -u duration desc  # play longest media first

    You can use multiple SQL ORDER BY expressions
    library watch -u 'subtitle_count > 0 desc' # play media that has at least one subtitle first

    Prioritize large-sized media
    library watch --sort 'ntile(10000) over (order by size/duration) desc'
    library watch -u 'ntile(100) over (order by size) desc'

    Sort by count of media with the same-X column (default DESC: most common to least common value)
    library watch -u same-duration
    library watch -u same-title
    library watch -u same-size
    library watch -u same-width, same-height ASC, same-fps
    library watch -u same-time_uploaded same-view_count same-upvote_ratio

    No media found when using --random
    In addition to -u/--sort random, there is also the -r/--random flag.
    If you have a large database it should be faster than -u random but it comes with a caveat:
    This flag randomizes via rowid at an earlier stage to boost performance.
    It is possible that you see "No media found" or a smaller amount of media than correct.
    You can bypass this by setting --limit. For example:
    library watch -B --folder-size=+12GiB --folder-size=-100GiB -r -pa
    path         count      size  duration                        avg_duration      avg_size

    path         count     size  duration                                 avg_duration      avg_size

Post-actions -- choose what to do after playing:
    library watch --post-action keep    # do nothing after playing (default)
    library watch -k delete             # delete file after playing
    library watch -k softdelete         # mark deleted after playing

    library watch -k ask_keep           # ask whether to keep after playing
    library watch -k ask_delete         # ask whether to delete after playing

    library watch -k move               # move to "keep" dir after playing
    library watch -k ask_move           # ask whether to move to "keep" folder
    The default location of the keep folder is ./keep/ (relative to the played media file)
    You can change this by explicitly setting an *absolute* `keep-dir` path:
    library watch -k ask_move --keep-dir /home/my/music/keep/

    library watch -k ask_move_or_delete # ask after each whether to move to "keep" folder or delete

Experimental options:
    Duration to play (in seconds) while changing the channel
    library watch --interdimensional-cable 40
    library watch -4dtv 40

    Playback multiple files at once
    library watch --multiple-playback    # one per display; or two if only one display detected
    library watch --multiple-playback 4  # play four media at once, divide by available screens
    library watch -m 4 --screen-name eDP # play four media at once on specific screen
    library watch -m 4 --loop --crop     # play four cropped videos on a loop
    library watch -m 4 --hstack          # use hstack style

Open tabs

$ library tabs -h
usage: library tabs DATABASE

Tabs is meant to run **once per day**. Here is how you would configure it with `crontab`:

    45 9 * * * DISPLAY=:0 library tabs /home/my/tabs.db

If things aren't working you can use `at` to simulate a similar environment as `cron`

    echo 'fish -c "export DISPLAY=:0 && library tabs /full/path/to/tabs.db"' | at NOW

You can also invoke tabs manually:

    library tabs -L 1  # open one tab

    $ library redownload city.db 2023-01-26T19:54:42 2023-01-26T20:45:24

Merge online and local data (merge-online-local)

$ library merge-online-local -h
usage: library merge-online-local DATABASE

If you have previously downloaded YouTube or other online media, you can dedupe
your database and combine the online and local media records as long as your
files have the youtube-dl / yt-dlp id in the filename.

Convert selftext links to media table (reddit-selftext)

$ library reddit-selftext -h
usage: library reddit-selftext DATABASE

Extract URLs from reddit selftext from the reddit_posts table to the media table

Search a SQLITE database (search-db)

$ library search-db -h
usage: library search-db DATABASE TABLE SEARCH ... [--delete]

Search all columns in a SQLITE table. If the table does not exist, uses the table which startswith (if only one match)

Merge SQLITE databases (merge-dbs)

$ library merge-dbs -h
usage: library merge-dbs DEST_DB SOURCE_DB ... [--only-target-columns] [--only-new-rows] [--upsert] [--pk PK ...] [--table TABLE ...]

Merge-DBs will insert new rows from source dbs to target db, table by table. If primary key(s) are provided,
and there is an existing row with the same PK, the default action is to delete the existing row and insert the new row
replacing all existing fields.

Upsert mode will update each matching PK row such that if a source row has a NULL field and
the destination row has a value then the value will be preserved instead of changed to the source row's NULL value.

Ignore mode (--only-new-rows) will insert only rows which don't already exist in the destination db

Test first by using temp databases as the destination db.
Try out different modes / flags until you are satisfied with the behavior of the program

    library merge-dbs --pk path (mktemp --suffix .db) tv.db movies.db

Merge database data and tables

    library merge-dbs --upsert --pk path video.db tv.db movies.db
    library merge-dbs --only-target-columns --only-new-rows --table media,playlists --pk path --skip-column id audio-fts.db audio.db

    library merge-dbs --pk id --only-tables subreddits reddit/81_New_Music.db audio.db
    library merge-dbs --only-new-rows --pk subreddit,path --only-tables reddit_posts reddit/81_New_Music.db audio.db -v

Dedupe SQLITE tables (dedupe-db)

$ library dedupe-db -h
usage: library dedupe-dbs DATABASE TABLE --bk BUSINESS_KEYS [--pk PRIMARY_KEYS] [--only-columns COLUMNS]

Dedupe your database (not to be confused with the dedupe subcommand)

It should not need to be said but *backup* your database before trying this tool!

Dedupe-DB will help remove duplicate rows based on non-primary-key business keys

    library dedupe-db ./video.db media --bk path

If --primary-keys is not provided table metadata primary keys will be used
If --only-columns is not provided all non-primary and non-business key columns will be upserted
If your duplicate rows contain exactly the same data in all the columns you can run with --skip-upsert to save a lot of time

Show large folders (bigdirs)

$ library bigdirs -h
usage: library bigdirs DATABASE [--limit (4000)] [--depth (0)] [--sort-by deleted | played] [--size=+5MB]

See what folders take up space

    library bigdirs video.db
    library bigdirs audio.db
    library bigdirs fs.db

lb bigdirs video.db --folder-size=+10G --lower 400 --upper 14000

lb bigdirs video.db --depth 5
lb bigdirs video.db --depth 7

Disk Usage (disk-usage)

$ library disk-usage -h
usage: library disk-usage DATABASE [--sort-by size | count] [--depth DEPTH] [PATH / SUBSTRING SEARCH]

Only include files smaller than 1kib

    library disk-usage du.db --size=-1Ki
    lb du du.db -S-1Ki

Import mpv watchlater files (mpv-watchlater)

$ library mpv-watchlater -h
usage: library mpv-watchlater DATABASE [--watch-later-directory ~/.config/mpv/watch_later/]

Extract timestamps from MPV to the history table

Sort data by similarity (cluster-sort)

$ library cluster-sort -h
usage: library cluster-sort [input_path | stdin] [output_path | stdout]

Group lines of text into sorted output

Scatter files between folders or disks

$ library scatter -h
usage: library scatter [--limit LIMIT] [--policy POLICY] [--sort SORT] --targets TARGETS DATABASE RELATIVE_PATHS ...

Balance files across filesystem folder trees or multiple devices (mostly useful for mergerfs)

Scatter filesystem folder trees (without mountpoints; limited functionality; good for balancing fs inodes)

    # move last week music back to their source folders
    library relmv /mnt/d/80_Now_Listening/ /mnt/d/

    # move new music for this week
    library relmv (
        library listen audio.db --local-media-only --where 'play_count=0' --random -L 600 -p f
    ) /mnt/d/80_Now_Listening/

Clean filenames (christen)

$ library christen -h
usage: library christen DATABASE [--run]

Rename files to be somewhat normalized

Default mode is dry-run

    library christen fs.db

To actually do stuff use the run flag

    library christen audio.db --run

You can optionally replace all the spaces in your filenames with dots

    library christen --dot-space video.db

Dedupe music

$ library dedupe -h
usage: library [--audio | --id | --title | --filesystem] [--only-soft-delete] [--limit LIMIT] DATABASE
