[Reddit][Ask] Specifying output format for Reddit extractor

[TheGlassEyedVillian]

Trying to figure out how I can configure "filename" for Reddit extractor in the config file
I've tried to use the --list-keywords option
But it doesn't return Filename options which in this case should be under Keywords for filename
Tried the same with Pixiv and Imgur which seem to work

Is there any way to set the same for Reddit?
In this case i'd like to extract the posts in the following manner
{id}_{title}.{extension}

I've tried this for Reddit based on the output

gallery-dl --list-keywords https://www.reddit.com/r/sadcats/comments/e6ua3c/_/

But this results in the filename being
None_None.jpg

How can i configure it so that my output file is named as
e6ua3c_ :(.jpg

Please ignore the illegal filename in this case its just for example

Thanks for reading through

as far as i know metadata for reddit is broken

[mikf]

… maybe not outright broken, just not implemented.

Reddit extractors are more or less only "URL fetchers" for submissions and comments. These URLs will get handled by other extractors according to their configuration, but there is currently no good way of using the Reddit metadata itself to build filenames.

You could use something like gallery-dl -d SUBREDDIT reddit.com/r/SUBREDDIT to put all media files from one subreddit into its own directory, but that's about it.

You could use something like gallery-dl -d SUBREDDIT reddit.com/r/SUBREDDIT to put all media files from one subreddit into its own directory, but that's about it.

That's what I've been doing with Reddit as well, whenever used so far.
And now that I think about it, something like this would probably be a good default setting here.
Or maybe use something like {base-dir}/reddit/SUBREDDIT, basically.
I don't know about you, but I think that would be the most likely expected behaviour here in this case. Feel free to disagree and give counterpoints, obviously.

I don't know about proper implementation, like always running something along the lines of -d SUBREDDIT implicitly, but I don't know what @mikf 's plans are with regard to any changes with the reddit extractor, or any other "architectural" changes in general.

[mikf]

I'm thinking of

1. Handling Reddit-hosted files "natively" (i.redd.it, v.redd.it) so it becomes possible to use the "reddit" section in your config file to define proper directory- and filenames for those, and
2. Implicitly changing the base-directory for spawned child extractors so any files downloaded by those will be included in the parent directory. Something like

reddit
└── lavaporn
    ├── e6bt0n Was told you guys would enjoy this..jpg
    ├── gfycat
    │   ├── gfycat_DazzlingAgitatedDromaeosaur_Wonder of Science …
    │   └── gfycat_SoggyRepulsiveAustraliancurlew_Close up of magma strands splitting apart.mp4
    └── imgur
    │   └── imgur_aosmMbD_Lava flow from the Pacaya volcano, with Agua, Acat…
…

Does this sound OK?

[Hrxn]

Yes, even better, in my opinion. I'd vote in favor of it.

[kattjevfel]

as long as it can be opted out from, I quite like the way it is now tbh.

[Hrxn]

@kattus , if I may ask, how do you sort stuff coming from a specific subreddit then?

@kattus , if I may ask, how do you sort stuff coming from a specific subreddit then?

I don't, my primary use for the reddit feature is downloading "saved" content.

Though I must add my main problem with the above suggestion is forcing filenames. I may have spoken a bit hastily, I suppose in the end it means I'll just have to force even more custom filenames, lovely.

[mikf]

Filenames for images and videos hosted on Reddit ([iv].redd.it) now use their submission's metadata and can be customized with extractor.reddit.filename.

Putting results from child extractors into their parent's directory can be enabled by enabling parent-directory for the parent extractor, e.g. reddit.

@kattus you can restore the old behavior by setting

• filename to "{filename}.{extension}" and
• directory to ["{category}"]
