Files not satisfying the conditions will not be downloaded. For example, `--length-tol` is set to 3 by default, meaning that files whose duration differs from the supplied duration by more than 3 seconds will not be downloaded (disable it by setting it to 99999).
Files satisfying `pref-` conditions will be preferred. For example, 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.
Configuration files: Create a file named `slsk-batchdl.conf` in the same directory as the executable and write your arguments there, e.g:
#### Name format:
Available tags are: artist, artists, album_artist, album_artists, title, album, year, track, disc, filename, default_foldername. Name format supports subdirectories as well as conditional expressions: `{str1|str2}` – If any tags in str1 are null, choose str2. String literals enclosed in parentheses are ignored in the null check.
```
{artist( - )title|album_artist( - )title|filename}
{album(/)}{track(. )}{artist|(unknown artist)} - {title|(unknown title)}
```
### Configuration files
Create a file named `slsk-batchdl.conf` in the same directory as the executable and write your arguments there, e.g:
```
--username "fakename"
--password "fakepass"
--pref-format "flac"
```
### Notes:
### Notes
- For Mac you can use publish.sh to build the app.
- The CSV file must use `"` as string delimiter and be encoded with UTF8.
- `--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. Adjust `--searches-per-time` and `--searches-time` in case it happens. By default it's 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. You can also use `--random-login` to re-login with a random username and password automatically.

- An issue I've not been able to resolve is audio files not appearing in the search results, even though they exist in the shown folders. This happens in soulseek clients as well; search for "AD PIANO IV Monochrome". You will find a few users whose folders only contain non-audio files. However, when you browse their shares, you can see that they do have audio in those exact folders. If you know why this is happening, please open an issue.
