Gelbooru - Exclude Uploader & Limit Tag

[DiegoACC02]

Hi,
Sorry for so many questions.
I'm downloading images from Gelbooru but many of them I already downloaded from Danbooru.
How can I exclude from the downloads where the uploader is "danbooru" and in the case of the character, limit it only for 2.
Currently I have it like this:

    "gelbooru":
    {
        "tags": true,
        "directory": ["Gelbooru", "{date:%Y-%m}"],
    "filename": "[{id}] [{tags_artist}] [{tags_character}] [{tags_copyright}] [{date:%Y%m%d}].{extension}"
    }

Thanks in advance for the support.

"image-filter": "owner != 'danbooru'",

in the case of the character, limit it only for 2.

That's kind of impossible with plain format strings, given that tags_character is just a plain string separated by spaces and possibly not defined.

You can limit the length of a field with [:50] or :X50/.../, but only by characters and not actual tags.

{tags_character|'':X50/.../}

What do you mean, in the same format that you downloaded? You can use your archive option for that.
IDs should be enough, but of course you can change "archive-format" to whatever you want.

I mean, with Mikf's help, I omit the owner "danbooru" from Gelbooru and modify the filename like this:
"filename": "[{id}] [{tags_artist}] [{tags_character}] [{tags_copyright}] [{owner}] [{date:%Y%m%d}].{extension}"
I did the same for Yandere, Safebooru, Zerochan and Konachan but it seems that in the case of them, "owner" is not the right tag since at the time of downloading the image in the brackets appears in the name of "None".
How could I know the name of the uploader tag for those domains?

An example of this for Gelbooru when I search for his uploader (owner):
Gelbooru
"filename": "[{id}] [{tags_artist}] [{tags_character}] [{tags_copyright}] [{owner}] [{date:%Y%m%d}].{extension}"
[11273135] [None] [yor_briar] [spy_x_family] [darthdaniel96] [20250109]

But for Yandere or Safebooru for example, where I put "owner" I get this:
"filename": "[{id}] [{tags_artist}] [{tags_character}] [{tags_copyright}] [{owner}] [{date:%Y%m%d}].{extension}"
[1212449] [jaduade] [raiden_shogun] [genshin_impact] [None] [20241227]

Well, yeah, different sites -> different tag names.
Content might not be consistently tagged across different sites, or maybe sometimes not even tagged correctly at all.

What are you trying to achieve by just blindly relying on the tags as provided by different sites?
Really relevant here is only if sites provided actual file-specific metadata, as a SHA1, SHA256, or whatever, hashsum for a single, specific image.

Hashsums/checksums provided as metadata are the only way to avoid such duplicates in the first place, before even downloading etc.

Otherwise, best is to deduplicate afterwards on your system.

  -K, --list-keywords         Print a list of available keywords and example
                              values for the given URLs

gallery-dl -j --range 1 URL is also an option.
