How to put reddit galleries into subfolders?

[Latrolage]

1. Is it possible to make gallery-dl create a folder and place files from the same gallery in this folder? How would i do this?

2. Is it possible to only show the number in front of files only when the number is larger than 0?
   I'm tried

"filename": "{num!r:R^0//} {title} {id} .{extension}"

But it doesn't seem to support regex

3. gallery-dl makes a subfolder called "None" and prepends "None" to the filename of imgur images from reddit?
   How do I make the folder name the same as the reddit post title and have the filename not have "None" prepended to it?

This my current config file i'm using

1. & 2. Yes, this is possible.
   I'll do the same, so I've simply taken a small excerpt from my own config here:

The trick is simply to add an additional element into the "directory" setting string list, if the reddit URL is from a gallery on reddit.

"reddit":
        {
            "submission":
            {
                "archive-format": "s_{subreddit}{filename}",
                "directory": {
                    "locals().get('is_gallery')": ["Reddit", "S", "{subreddit!C}", "{title[:120]!t:?/_/R /_/}{id}"],
                    ""                          : ["Reddit", "S", "{subreddit!C}"]
                },
                "filename": {
                    "locals().get('is_gallery')": "{title[:120]!t:?/_/R /_/}{id}{num:?_//>02}.{extension}",
                    ""                          : "{title[:120]!t:?/_/R /_/}{id}.{extension}"
                },
            },
        }

3. "None" simply means that you tried to access & insert a field into your output string that does not exist.
   You can change this with the "keywords-default" option, by setting it to any other string you like, or to the empty string "", this way nothing will actually show up in your output.

What do you mean with subfolder here? Reddit does not integrate galleries/album pages from Imgur, as far as I know. If you have an example link that shows otherwise, I'd like to see it myself.

If you simply mean single images hosted on Imgur that are directly linked on Reddit: Yes, it is possible to take the title from reddit.

Just two steps:

• Add these two options to your "reddit" section of the config file (like above):

            "parent-directory": true,
            "parent-metadata": "_reddit",

gallery-dl extracts stuff hosted on Imgur but coming in from Reddit by spawning an Imgur child-extractor.

• Then use this in your "imgur" section;

        "imgur":
        {
            "image":
            {
                  "directory": {
                    "'_reddit' in locals()"                                 : [],
                    "extension in ('mp4', 'webm')"                          : ["Imgur", "Anims"],
                    ""                                                      : ["Imgur", "Pics"]
                },
                "filename": {
                    "'_reddit' in locals()"     : "{_reddit[title][:180]!t:?/_/R /_/}{_reddit[id]}.{extension}",
                    "not locals().get('title')" : "{id}.{extension}",
                    ""                          : "{title!t:R /_/}_{description!t:?/_/}{id}.{extension}"
                }

Thanks for the reply, it seems do what i wanted in 1 and 2. I'll go fiddle around with 3 for a bit. Where is _reddit' in locals() documented? I don't understand what it does

Also is it normal that {subreddit!C} uncapitalizes characters in the string?

Foo_Bar became Foo_bar if i had !C, if i did not use !C then it would be Foo_Bar (which is what i wanted)

Edit: I think i got point 3 working with:

        "imgur":
        {
            "mp4": true,
            "image":
            {
                "directory": {
                    "'_reddit' in locals()"                                 : ["{_reddit[subreddit]}"],
                    "extension in ('mp4', 'webm')"                          : ["Imgur", "Anims"],
                    ""                                                      : ["Imgur", "Pics"]
                },
                "filename": {
                    "'_reddit' in locals()"     : "{_reddit[title][:180]!t:?/_/R /_/}{_reddit[id]}.{extension}",
                    "not locals().get('title')" : "{id}.{extension}",
                    ""                          : "{title!t:R /_/}_{description!t:?/_/}{id}.{extension}"
                }
            }
        },
        "reddit":
        {
            "category-transfer": false,
            "parent-directory": false,
            "parent-metadata": "_reddit",

Yeah, I've taken these examples from my own config except for some modifications, but I probably should have removed all other formatting options like !C, which I use to make the capitalization of letters somewhat more consistent.

Simply use {subreddit} to get the name of the subreddit as given by the site.

The _reddit keyword is an example of the "parent-metadata" option, to hand over metadata from a parent extractor to a child extractor, it's documented here

It's also shown in the example config file here: https://github.com/mikf/gallery-dl/blob/master/docs/gallery-dl-example.conf

Where is _reddit' in locals() documented? I don't understand what it does

Nowhere in this repo. locals() is a built-in Python function that returns a list of all local variables. '_reddit' in locals() checks if there is a variable called _reddit to check whether this imgur extractor was spawned by a reddit extractor and got its metadata ("parent-metadata": "_reddit") or not.
