downloaded successfully.
```
```
Searching
--fast-search Begin downloading as soon as a file satisfying the preferred
conditions is found. Higher chance to download wrong files.
--remove-ft Remove 'feat.' and everything after before searching
--no-remove-special-chars Do not remove special characters before searching
--remove-brackets Remove square brackets and their contents before searching
--regex <regex> Remove a regexp from all track titles and artist names.
Optionally specify a replacement regex after a semicolon.
Add 'T:', 'A:' or 'L:' at the start to only apply this to
the track title, artist, or album respectively.
--artist-maybe-wrong Performs an additional search without the artist name.
Useful for sources like SoundCloud where the "artist"
could just be an uploader. Note that when downloading a
YouTube playlist via url, this option is set automatically
on a per-track basis, so it is best kept off in that case.
-d, --desperate Tries harder to find the desired track by searching for the
artist/album/title only, then filtering. (slower search)
--fails-to-downrank <num> Number of fails to downrank a user's uploads (default: 1)
--fails-to-ignore <num> Number of fails to ban/ignore a user's uploads (default: 2)
--yt-dlp Use yt-dlp to download tracks that weren't found on
Soulseek. yt-dlp must be available from the command line.
--yt-dlp-argument <str> The command line arguments when running yt-dlp. Default:
"{id}" -f bestaudio/best -cix -o "{savepath}.%(ext)s"
Available vars are: {id}, {savedir}, {savepath} (w/o ext).
Note that with -x, yt-dlp will download webms in case
ffmpeg is unavailable.
--search-timeout <ms> Max search time in ms (default: 6000)
--max-stale-time <ms> Max download time without progress in ms (default: 50000)
--searches-per-time <num> Max searches per time interval. Higher values may cause
30-minute bans, see --help "search". (default: 34)
--searches-renew-time <sec> Controls how often available searches are replenished.
See --help "search". (default: 220)

Notes
Acronyms of two- and --three-word-flags are also accepted, e.g. --twf. If the option
contains the word 'max' then the m should be uppercase. 'bitrate', 'sameplerate' and
'bitdepth' should be all treated as two separate words, e.g --Mbr for --max-bitrate.
Flags can be explicitly disabled by setting them to false, e.g '--interactive false'
```
## Input types
The input type is usually determined automatically. To force a specific input type, set
--input-type [spotify|youtube|csv|string|bandcamp]. The following input types are available:
### CSV file
Path to a local CSV file: Use a csv file containing track info of the songs to download.
The names of the columns should be Artist, Title, Album, Length, although alternative names
are usually detected as well. Only the title or album column is required, but extra info may
improve search results. Every row that does not have a title column text will be treated as an
album download.
### YouTube
A playlist url: Download songs from a youtube playlist.
The default method to retrieve playlists doesn't always return all videos, especially not
the ones which are unavailable. To get all video titles, you can use the official API by
providing a key with --youtube-key. Get it here https://console.cloud.google.com. Create a
new project, click "Enable Api" and search for "youtube data", then follow the prompts.
Tip: For playlists containing music videos, it may be better to remove all text in parentheses
(to remove (Lyrics), (Official), etc) and disable song duration checking:
--regex "[\[\(].*?[\]\)]" --pref-length-tol -1
### Spotify
A playlist/album url or 'spotify-likes': Download a spotify playlist, album, or your
liked songs. --spotify-id and --spotify-secret are required in addition when downloading
a private playlist or liked music.
The id and secret can be obtained at https://developer.spotify.com/dashboard/applications.
Create an app and add http://localhost:48721/callback as a redirect url in its settings.
### Bandcamp
An bandcamp url: Download a single track, and album, or an artist's entire discography.
Extracts the artist name, album name and sets --album-track-count=""n+"", where n is the
number of visible tracks on the bandcamp page.
### Search string
Name of the track, album, or artist to search for: Can either be any typical search string
(like what you would enter into the soulseek search bar), or a comma-separated list of
properties like 'title=Song Name, artist=Artist Name, length=215'.
The following properties are allowed:
```
title
artist
album
length (in seconds)
artist-maybe-wrong
```
Example inputs and their interpretations:
```
Input String | Artist | Title | Album | Length
---------------------------------------------------------------------------------
'Foo Bar' (without any hyphens) | | Foo Bar | |
'Foo - Bar' | Foo | Bar | |
'Foo - Bar' (with --album enabled) | Foo | | Bar |
'Artist - Title, length=42' | Artist | Title | | 42
'artist=AR, title=T, album=AL' | AR | T | AL |
```
## Download modes
### Normal
The program will download a single file for every input entry.
### Album
The program will search for the album and download an entire folder including non-audio
files. Activated when the input is a link to a spotify or bandcamp album, when the input
string or csv row has no track title, or when -a/--album is enabled.
### Aggregate
With -g/--aggregate, the program will first perform an ordinary search for the input, then
attempt to group the results into distinct songs and download one of each kind. A common use
case is finding all remixes of a song or printing all songs by an artist that are not your
music dir.
Two files are considered equal if their inferred track title and artist name are equal
(ignoring case and some special characters), and their lengths are within --length-tol of each
other.
Note that this mode is not 100% reliable, which is why --min-users-aggregate is set to 2 by default,
i.e. any song that is shared by only one peer will be ignored. Enable --relax-filtering to
make the file filtering less aggressive.
### Album Aggregate
Activated when --album and --aggregate are enabled, in this mode sldl searches for the query
and groups results into distinct albums. Two folders are considered same if they have the
same number of audio files, and the durations of the files are within --length-tol of each
other (or within 3 seconds if length-tol is not configured). If both folders have exactly one
audio file with similar lengths, also checks if the inferred title and artist name coincide.
More reliable than normal aggregate due to much simpler grouping logic.
Note that --min-users-aggregate is 2 by default, which means that folders shared by only one
peer are ignored.
## Searching
### Soulseek's rate limits
The server will ban you for 30 minutes if too many searches are performed within a short
timespan. The program has a search limiter which can be adjusted with --searches-per-time
and --searches-renew-time (when the limit is reached, the status of the downloads will be
"Waiting"). By default it is configured to allow up to 34 searches every 220 seconds.
The default values were determined through experimentation, so they may be incorrect.
### Quality vs Speed
The following options will make it go faster, but may decrease search result quality or cause
instability:
- --fast-search skips waiting until the search completes and downloads as soon as a file
matching the preferred conditions is found
- --concurrent-downloads - set it to 4 or more
- --max-stale-time is set to 50 seconds by default, so it will wait a long time before giving
up on a file
- --searches-per-time increase at the risk of bans.
### Quality vs Quantity
The options --strict-title, --strict-artist and --strict-album will filter any file that
does not contain the title/artist/album in the filename (ignoring case, bounded by boundary
chars).
Another way to prevent false downloads is to set --length-tol to 3 or less to make it ignore
any songs that differ from the input by more than 3 seconds. However, all 4 options are already
enabled as 'preferred' conditions by default, meaning that such files will only be downloaded
as a last resort anyways. Hence it is only recommended to enable them if you need to minimize
false downloads as much as possible.
## File conditions
Files not satisfying the required conditions will not be downloaded. Files satisfying pref-
conditions will be preferred; setting --pref-format "flac,wav" will make it download lossless
files if available, and only download lossy files if there's nothing else.
There are no default required conditions. The default preferred conditions are:
```
format = mp3
length-tol = 3
min-bitrate = 200
max-bitrate = 2500
max-samplerate = 48000
strict-title = true
strict-album = true
accept-no-length = false
```
sldl will therefore prefer mp3 files with bitrate between 200 and 2500 kbps, and whose length
differs from the supplied length by no more than 3 seconds. It will also prefer files whose
paths contain the supplied artist and album (ignoring case, and bounded by boundary characters)
and which have a non-null length. Changing the last three preferred conditions is not recommended.
### Important note
Some info may be unavailable depending on the client used by the peer. For example, the standard
Soulseek client does not share the file bitrate. If (e.g) --min-bitrate is set, then sldl will
still accept any file with unknown bitrate. You can configure it to reject all files where one
or more of the checked properties is null (unknown) by enabling --strict-conditions.
As a consequence, if --min-bitrate is also set then any files shared by users with the default
client will be ignored. Also note that the default preferred conditions will already affect
ranking with this option due to the bitrate and samplerate checks.
Conditions can also be supplied as a semicolon-delimited string with --cond and --pref, e.g
--cond "br>=320;f=mp3,ogg;sr<96000"
## Name format
Variables enclosed in {} will be replaced by the corresponding file tag value.
Name format supports subdirectories as well as conditional expressions like {tag1|tag2} - If
tag1 is null, use tag2. String literals enclosed in parentheses are ignored in the null check.
### Examples:
- "{artist} - {title}"
Always name it 'Artist - Title'. Because some files on Soulseek are untagged, the
following is generally preferred:
- "{artist( - )title|filename}"
If artist and title are not null, name it 'Artist - Title', otherwise use the original
filename.
### Available variables:
```
artist First artist (from the file tags)
sartist Source artist (as on CSV/Spotify/YouTube/etc)
artists Artists, joined with '&'
albumartist First album artist
albumartists Album artists, joined with '&'
title Track title
stitle Source track title
album Album name
salbum Source album name
year Track year or date
track Track number
disc Disc number
filename Soulseek filename without extension
foldername Default sldl folder name
extractor Name of the extractor used (CSV/Spotify/YouTube/etc)
```
## Skip existing
sldl can skip files that exist in the download directory or a specified directory configured with
--music-dir.
The following modes are available for --skip-mode:
### m3u
Default when checking in the output directory.
Checks whether the output m3u file contains the track in the '#SLDL' line. Does not check if
the audio file exists or satisfies the file conditions (use m3u-cond for that).
### name
Compares filenames to the track title and artist name to determine if a track already exists.
Specifically, a track will be skipped if there exists a file whose name contains the title
and whose full path contains the artist name.
### tag
Compares file tags to the track title and artist name. A track is skipped if there is a file
whose artist tag contains the track artist and whose title tag equals the track title
(ignoring case and ws). Slower than name mode as it needs to read all file tags.
### m3u-cond, name-cond, tag-cond
Default for checking in --music-dir: name-cond.
Same as the above modes but also checks whether the found file satisfies necessary conditions.
Equivalent to the above modes if no necessary conditions have been specified (except m3u-cond
which always checks if the file exists). May be slower and use a lot of memory for large
libraries.
## Configuration
### Config Location:
sldl will look for a file named sldl.conf in the following locations:
```
~/AppData/Roaming/sldl/sldl.conf
~/.config/sldl/sldl.conf
```
as well as in the directory of the executable.
### Syntax:
Example config file:
```
username = your-username
password = your-password
pref-format = flac
fast-search = true
```
Lines starting with hashtags (#) will be ignored. Tildes in paths are expanded as the user
directory.
### Configuration profiles:
Profiles are supported:
```
[lossless]
pref-format = flac,wav
```
To activate the above profile, run --profile "lossless". To list all available profiles,
run --profile "help".
Profiles can be activated automatically based on a few simple conditions:
```
[no-stale]
profile-cond = interactive && download-mode == "album"
max-stale-time = 999999
# album downloads will never be automatically cancelled in interactive mode
[youtube]
profile-cond = input-type == "youtube"
path = ~/downloads/sldl-youtube
# download to another location for youtube
```
The following operators are supported: &&, ||, ==, !=, ! (negation for bools).
The following variables are available for use in profile-cond:
```
input-type ( = "youtube"|"csv"|"string"|"bandcamp"|"spotify")
download-mode ( = "normal"|"aggregate"|"album"|"album-aggregate")
interactive (bool)
```
## Examples
Download tracks from a csv file:
```
sldl test.csv
```
<details>
<summary>CSV details</summary>
The names of the columns in the csv should be: `Artist`, `Title`, `Album`, `Length`. Some alternatives are also accepted. You can use `--print tracks` before downloading to check if everything has been parsed correctly. Only the title or album column is required, but additional info may improve search results.
</details>
<br>
Download spotify likes while skipping songs that already exist in the output folder:
```
sldl spotify-likes --skip-existing
```
<details>
<summary>Spotify details</summary>
To download private playlists or liked songs you will need to provide a client id and secret, which you can get here https://developer.spotify.com/dashboard/applications. Create an app and add `http://localhost:48721/callback` as a redirect url in its settings.
</details>
<br>
Download from a youtube playlist with fallback to yt-dlp in case it is not found on soulseek, and retrieve deleted video titles from wayback machine:
```
sldl "https://www.youtube.com/playlist?list=PLI_eFW8NAFzYAXZ5DrU6E6mQ_XfhaLBUX" --get-deleted --yt-dlp
```
<details>
<summary>YouTube details</summary>
Playlists are retrieved using the YoutubeExplode library which unfortunately doesn't always return all videos. You can use the official API by providing a key with `--youtube-key`. Get it here https://console.cloud.google.com. Create a new project, click "Enable Api" and search for "youtube data", then follow the prompts.
Also note that due the high number of music videos in the above example playlist, it may be better to remove all text in parentheses and disable song duration checking: `--regex "[\[\(].*?[\]\)]" --pref-length-tol -1`.
</details>
<br>
Search & download a specific song, preferring lossless:
```
sldl "title=MC MENTAL @ HIS BEST,length=242" --pref-format "flac,wav"
```
<details>
<summary>String details</summary>
The shorthand `sldl "Artist - Title"` is equivalent to `sldl "artist=Artist,title=Title"`.
</details>
<br>
Interactive album download:
```
sldl "album=Some Album" --interactive
```
<details>
<summary>Album details</summary>
The shorthand `sldl "Artist - Album" -a` is equivalent to `sldl "artist=Artist,album=Album"`. It's often helpful to restrict to folders which have two or more tracks: `--atc 2+`.
</details>
<br>
Print all songs by an artist which are not in your library:
```
sldl "artist=MC MENTAL" --aggregate --skip-existing --music-dir "path/to/music" --print tracks-full
```
<br>
## Download Modes
Depending on the provided input, the download behaviour changes:
- Normal download: The program will download a single file for every input entry.
- Album download: The program will search for the album and download an entire folder including non-audio files. Activated when the input is a link to a spotify or bandcamp album, when the input string or csv row has no track title, or when `-a`/`--album` is enabled.
- Aggregate download: With `-g`/`--aggregate`, the program will first perform an ordinary search for the input, then attempt to group the results into distinct songs and download one of each kind. This can be used to download an artist's entire discography (or simply printing it, like in the example above), finding remixes of a song, etc. Note that it is not 100% reliable, which is why `--min-users-aggregate` is set to 2 by default, i.e. any song that is shared by only one person will be ignored. Enable `--relax-filtering` to make the file filtering less aggressive.

-g --aggregate Instead of downloading a single track matching the input,
find and download all distinct songs associated with the
provided artist, album, or track title.
--min-users-aggregate <num> Minimum number of users sharing a track before it is
downloaded in aggregate mode. Setting it to higher values
will significantly reduce false positives, but also cause it
to ignore rarer songs. Default: 2
--relax-filtering Slightly relax file filtering in aggregate mode to include
more results
-s --skip-existing Skip if a track matching file conditions is found in the
output folder or your music library (if provided)
--skip-mode <mode> 'name': Use only filenames to check if a track exists
'name-precise' (default): Use filenames and check conditions
'tag': Use file tags (slower)
'tag-precise': Use file tags and check file conditions
'm3u': Skip all tracks that don't have a fail entry in m3u
--music-dir <path> Specify to also skip downloading tracks found in a music
library. Use with --skip-existing
--skip-not-found Skip searching for tracks that weren't found on Soulseek
during the last run. Fails are read from the m3u file.
--no-remove-special-chars Do not remove special characters before searching
--remove-ft Remove 'feat.' and everything after before searching
--remove-brackets Remove square brackets and their contents before searching
--regex <regex> Remove a regexp from all track titles and artist names.
Optionally specify a replacement regex after a semicolon.
Add 'T:', 'A:' or 'L:' at the start to only apply this to
the track title, artist, or album respectively.
--artist-maybe-wrong Performs an additional search without the artist name.
Useful for sources like SoundCloud where the "artist"
could just be an uploader. Note that when downloading a
YouTube playlist via url, this option is set automatically
on a per-track basis, so it is best kept off in that case.
-d --desperate Tries harder to find the desired track by searching for the
artist/album/title only, then filtering. (slower search)
--yt-dlp Use yt-dlp to download tracks that weren't found on
Soulseek. yt-dlp must be available from the command line.
--yt-dlp-argument <str> The command line arguments when running yt-dlp. Default:
"{id}" -f bestaudio/best -cix -o "{savepath}.%(ext)s"
Available vars are: {id}, {savedir}, {savepath} (w/o ext).
Note that with -x, yt-dlp will download webms in case
ffmpeg is unavailable.
-c --config <path> Set config file location
--search-timeout <ms> Max search time in ms (default: 5000)
--max-stale-time <ms> Max download time without progress in ms (default: 50000)
--concurrent-downloads <num> Max concurrent downloads (default: 2)
--searches-per-time <num> Max searches per time interval. Higher values may cause
30-minute bans. (default: 34)
--searches-renew-time <sec> Controls how often available searches are replenished.
Lower values may cause 30-minute bans. (default: 220)
--display-mode <option> Changes how searches and downloads are displayed:
'single' (default): Show transfer state and percentage
'double': Transfer state and a large progress bar
'simple': No download bars or changing percentages
--listen-port <port> Port for incoming connections (default: 50000)
--print <option> Print tracks or search results instead of downloading:
'tracks': Print all tracks to be downloaded
'tracks-full': Print extended information about all tracks
'results': Print search results satisfying file conditions
'results-full': Print search results including full paths
--debug Print extra debug info
sldl "artist=MC MENTAL" --aggregate --album
```
### File conditions
Files not satisfying the conditions will not be downloaded. Files satisfying `pref-` conditions will be preferred; setting `--pref-format "flac,wav"` will make it download high quality files if they exist, and only download low quality files if there's nothing else. Conditions can also be supplied as a semicolon-delimited string to `--cond` and `--pref`, e.g `--cond "br>=320;f=mp3,ogg;sr<96000"`. See the start of `Program.cs` for the default file conditions.
**Important note**: Some info may be unavailable depending on the client used by the peer. For example, the default Soulseek client does not share the file bitrate. By default, if `--min-bitrate` is set, then files with unknown bitrate will still be downloaded. You can configure it to reject all files where one of the checked properties is unavailable by enabling `--strict-conditions`. (As a consequence, if `--min-bitrate` is also set then any files shared by users with the default client will be ignored)
### Name format
Variables enclosed in {} will be replaced by the corresponding file tag value. Available variables are: artist, sartist, artists, albumartist, albumartists, title, stitle, album, salbum, year, track, disc, filename, foldername. The variables sartist, stitle and salbum will be replaced by the source artist, title and album respectively (i.e what is shown in spotify/youtube/csv file) instead of the tag values of the downloaded file. Name format supports subdirectories as well as conditional expressions like `{tag1|tag2}` – If tag1 is null, choose tag2. String literals enclosed in parentheses are ignored in the null check. Examples:
- `{artist} - {title}`: Always name it 'Artist - Title'. Because some files on Soulseek do not have tags, the second example is preferred:
- `{artist( - )title|filename}`: If artist and title is not null, name it 'Artist - Title', otherwise use the original filename.
### Quality vs Speed
The following options will make it go faster, but may decrease search result quality or cause instability:
- `--fast-search` skips waiting until the search completes and downloads as soon as a file matching the preferred conditions is found
- `--concurrent-downloads` - set it to 4 or more
- `--max-stale-time` is set to 50 seconds by default, so it will wait a long time before giving up on a file
- `--searches-per-time` increase at the risk of ban, see the notes section for details.
### Quality vs Quantity
The options `--strict-title`, `--strict-artist` and `--strict-album` will filter any file that does not contain the title/artist/album in the filename (ignoring case, bounded by boundary chars). Another way to prevent false downloads is to set `--length-tol` to 3 or less to make it ignore any songs that differ from the input by more than 3 seconds. However, all 4 options are already enabled as 'preferred' conditions by default, meaning that such files will only be downloaded as a last resort even without enabling these. Hence it is only recommended to enable them if you need to minimize false downloads as much as possible.
## Configuration
Create a file named `sldl.conf` in the same directory as the executable and write your arguments there, e.g:
```
username = fakename
password = fakepass
pref-format = flac
fast-search = true
```
## Notes
- For macOS builds you can use publish.sh to build the app. Download dotnet from https://dotnet.microsoft.com/en-us/download/dotnet/6.0, then run `chmod +x publish.sh && sh publish.sh`. For intel macs, uncomment the x64 and comment the arm64 section in publish.sh.
- `--display single` and especially `double` can cause the printed lines to be duplicated or overwritten on some configurations. Use `simple` if that's an issue.
- The server will ban you for 30 minutes if too many searches are performed within a short timespan. The program has a search limiter which can be adjusted with `--searches-per-time` and `--searches-renew-time` (when limit is reached, the status of the downloads will be "Waiting"). By default it is configured to allow up to 34 searches every 220 seconds. These values were determined through experimentation as unfortunately I couldn't find any information regarding soulseek's rate limits, so they may be incorrect.

the track title, artist, or album respectively.
--artist-maybe-wrong Performs an additional search without the artist name.
Useful for sources like SoundCloud where the ""artist""
could just be an uploader. Note that when downloading a
YouTube playlist via url, this option is set automatically
on a per-track basis, so it is best kept off in that case.
-d, --desperate Tries harder to find the desired track by searching for the
artist/album/title only, then filtering. (slower search)

Notes
Acronyms of two- and --three-word-flags are also accepted, e.g. --twf. If the option
contains the word 'max' then the m should be uppercase. 'bitrate', 'sameplerate' and
'bitdepth' should be all treated as two separate words, e.g --Mbr for --max-bitrate.
Flags can be explicitly disabled by setting them to false, e.g '--interactive false'
";
const string inputHelp = @"
Input types
The input type is usually determined automatically. To force a specific input type, set
--input-type [spotify|youtube|csv|string|bandcamp]. The following input types are available:
CSV file
Path to a local CSV file: Use a csv file containing track info of the songs to download.
The names of the columns should be Artist, Title, Album, Length, although alternative names
are usually detected as well. Only the title or album column is required, but extra info may
improve search results. Every row that does not have a title column text will be treated as an
album download.
YouTube
A playlist url: Download songs from a youtube playlist.
The default method to retrieve playlists doesn't always return all videos, especially not
the ones which are unavailable. To get all video titles, you can use the official API by
providing a key with --youtube-key. Get it here https://console.cloud.google.com. Create a
new project, click ""Enable Api"" and search for ""youtube data"", then follow the prompts.
Tip: For playlists containing music videos, it may be better to remove all text in parentheses
(to remove (Lyrics), (Official), etc) and disable song duration checking:
--regex ""[\[\(].*?[\]\)]"" --pref-length-tol -1
Spotify
A playlist/album url or 'spotify-likes': Download a spotify playlist, album, or your
liked songs. --spotify-id and --spotify-secret are required in addition when downloading
a private playlist or liked music.
The id and secret can be obtained at https://developer.spotify.com/dashboard/applications.
Create an app and add http://localhost:48721/callback as a redirect url in its settings.
Bandcamp
An bandcamp url: Download a single track, and album, or an artist's entire discography.
Extracts the artist name, album name and sets --album-track-count=""n+"", where n is the
number of visible tracks on the bandcamp page.
Search string
Name of the track, album, or artist to search for: Can either be any typical search string
(like what you would enter into the soulseek search bar), or a comma-separated list of
properties like 'title=Song Name, artist=Artist Name, length=215'.
The following properties are allowed:
title
artist
album
length (in seconds)
artist-maybe-wrong
Example inputs and their interpretations:
Input String | Artist | Title | Album | Length
---------------------------------------------------------------------------------
'Foo Bar' (without any hyphens) | | Foo Bar | |
'Foo - Bar' | Foo | Bar | |
'Foo - Bar' (with --album enabled) | Foo | | Bar |
'Artist - Title, length=42' | Artist | Title | | 42
'artist=AR, title=T, album=AL' | AR | T | AL |
";
const string downloadModesHelp = @"
Download modes
Normal
The program will download a single file for every input entry.
Album
The program will search for the album and download an entire folder including non-audio
files. Activated when the input is a link to a spotify or bandcamp album, when the input
string or csv row has no track title, or when -a/--album is enabled.
Aggregate
With -g/--aggregate, the program will first perform an ordinary search for the input, then
attempt to group the results into distinct songs and download one of each kind. A common use
case is finding all remixes of a song or printing all songs by an artist that are not your
music dir.
Two files are considered equal if their inferred track title and artist name are equal
(ignoring case and some special characters), and their lengths are within --length-tol of each
other.
Note that this mode is not 100% reliable, which is why --min-users-aggregate is set to 2 by
default, i.e. any song that is shared by only one peer will be ignored. Enable --relax-filtering
to make the file filtering less aggressive.
Album Aggregate
Activated when --album and --aggregate are enabled, in this mode sldl searches for the query
and groups results into distinct albums. Two folders are considered same if they have the
same number of audio files, and the durations of the files are within --length-tol of each
other (or within 3 seconds if length-tol is not configured). If both folders have exactly one
audio file with similar lengths, also checks if the inferred title and artist name coincide.
More reliable than normal aggregate due to much simpler grouping logic.
Note that --min-users-aggregate is 2 by default, which means that folders shared by only one
peer are ignored.
";
const string searchHelp = @"
Searching
Soulseek's rate limits
The server will ban you for 30 minutes if too many searches are performed within a short
timespan. The program has a search limiter which can be adjusted with --searches-per-time
and --searches-renew-time (when the limit is reached, the status of the downloads will be
""Waiting""). By default it is configured to allow up to 34 searches every 220 seconds.
The default values were determined through experimentation, so they may be incorrect.
Quality vs Speed
The following options will make it go faster, but may decrease search result quality or cause
instability:
--fast-search skips waiting until the search completes and downloads as soon as a file
matching the preferred conditions is found
--concurrent-downloads - set it to 4 or more
--max-stale-time is set to 50 seconds by default, so it will wait a long time before giving
up on a file
--searches-per-time increase at the risk of bans.
Quality vs Quantity
The options --strict-title, --strict-artist and --strict-album will filter any file that
does not contain the title/artist/album in the filename (ignoring case, bounded by boundary
chars).
Another way to prevent false downloads is to set --length-tol to 3 or less to make it ignore
any songs that differ from the input by more than 3 seconds. However, all 4 options are already
enabled as 'preferred' conditions by default, meaning that such files will only be downloaded
as a last resort anyways. Hence it is only recommended to enable them if you need to minimize
false downloads as much as possible.
";
const string fileConditionsHelp = @"
File conditions
Files not satisfying the required conditions will not be downloaded. Files satisfying pref-
conditions will be preferred; setting --pref-format ""flac,wav"" will make it download lossless
files if available, and only download lossy files if there's nothing else.
There are no default required conditions. The default preferred conditions are:
format = mp3
length-tol = 3
min-bitrate = 200
max-bitrate = 2500
max-samplerate = 48000
strict-title = true
strict-album = true
accept-no-length = false
sldl will therefore prefer mp3 files with bitrate between 200 and 2500 kbps, and whose length
differs from the supplied length by no more than 3 seconds. It will also prefer files whose
paths contain the supplied artist and album (ignoring case, and bounded by boundary characters)
and which have a non-null length. Changing the last three preferred conditions is not recommended.
Important note
Some info may be unavailable depending on the client used by the peer. For example, the standard
Soulseek client does not share the file bitrate. If (e.g) --min-bitrate is set, then sldl will
still accept any file with unknown bitrate. You can configure it to reject all files where one
or more of the checked properties is null (unknown) by enabling --strict-conditions.
As a consequence, if --min-bitrate is also set then any files shared by users with the default
client will be ignored. Also note that the default preferred conditions will already affect
ranking with this option due to the bitrate and samplerate checks.
Conditions can also be supplied as a semicolon-delimited string with --cond and --pref, e.g
--cond ""br>=320;f=mp3,ogg;sr<96000""
";
const string nameFormatHelp = @"
Name format
Variables enclosed in {} will be replaced by the corresponding file tag value.
Name format supports subdirectories as well as conditional expressions like {tag1|tag2} - If
tag1 is null, use tag2. String literals enclosed in parentheses are ignored in the null check.
Examples:
""{artist} - {title}""
Always name it 'Artist - Title'. Because some files on Soulseek are untagged, the
following is generally preferred:
""{artist( - )title|filename}""
If artist and title are not null, name it 'Artist - Title', otherwise use the original
filename.
Available variables:
artist First artist (from the file tags)
sartist Source artist (as on CSV/Spotify/YouTube/etc)
artists Artists, joined with '&'
albumartist First album artist
albumartists Album artists, joined with '&'
title Track title
stitle Source track title
album Album name
salbum Source album name
year Track year or date
track Track number
disc Disc number
filename Soulseek filename without extension
foldername Default sldl folder name
extractor Name of the extractor used (CSV/Spotify/YouTube/etc)
";
const string skipExistingHelp = @"
Skip existing
sldl can skip files that exist in the download directory or a specified directory configured with
--music-dir.
The following modes are available for --skip-mode:
m3u
Default when checking in the output directory.
Checks whether the output m3u file contains the track in the '#SLDL' line. Does not check if
the audio file exists or satisfies the file conditions, use m3u-cond for that.
name
Compares filenames to the track title and artist name to determine if a track already exists.
Specifically, a track will be skipped if there exists a file whose name contains the title
and whose full path contains the artist name.
tag
Compares file tags to the track title and artist name. A track is skipped if there is a file
whose artist tag contains the track artist and whose title tag equals the track title
(ignoring case and ws). Slower than name mode as it needs to read all file tags.
m3u-cond, name-cond, tag-cond
Default for checking in --music-dir: name-cond.
Same as the above modes but also checks whether the found file satisfies necessary conditions.
Equivalent to the above modes if no necessary conditions have been specified (except m3u-cond
which always checks if the file exists). May be slower and use a lot of memory for large
libraries.
";
const string configHelp = @"
Configuration
Config Location:
sldl will look for a file named sldl.conf in the following locations:
~/AppData/Roaming/sldl/sldl.conf
~/.config/sldl/sldl.conf
as well as in the directory of the executable.
Syntax:
Example config file:
username = your-username
password = your-password
pref-format = flac
fast-search = true
Lines starting with hashtags (#) will be ignored. Tildes in paths are expanded as the user
directory.
Configuration profiles:
Profiles are supported:
[lossless]
pref-format = flac,wav
To activate the above profile, run --profile ""lossless"". To list all available profiles,
run --profile ""help"".
Profiles can be activated automatically based on a few simple conditions:
[no-stale]
profile-cond = interactive && download-mode == ""album""
max-stale-time = 999999
# album downloads will never be automatically cancelled in interactive mode
[youtube]
profile-cond = input-type == ""youtube""
path = ~/downloads/sldl-youtube
# download to another location for youtube
The following operators are supported: &&, ||, ==, !=, ! (negation for bools).
The following variables are available for use in profile-cond:
input-type ( = ""youtube""|""csv""|""string""|""bandcamp""|""spotify"")
download-mode ( = ""normal""|""aggregate""|""album""|""album-aggregate"")
interactive (bool)
