When you run the script, it will show a textarea with the markdown code for crediting sources. I use it to save time when posting to Lemmy.

Usual disclaimer: I’ve tested it but only to a certain point (with my environment). If you find any issue you don’t know how to fix, let me know.

EDIT: Here are the scripts in pastebin raw text (lemmy currently replaces the ampersand signs with & and it breaks the scripts:

• one liner
• pretty print

Tip (for firefox users): you can set a keyword for a bookmarklet that you can run form the navbar. Once you get used to “Control+L (focus navbar) > keyword” it becomes really frictionless.

For generic pages, the output is:

Source: [Page title](page_url)

For Tumblr posts the outuput is:

Source: [Page title](page_url)

Tumblr archive: https://site_url/archive

RSS Feed: https://site_url/rss

For ArtStation pages the outuput is:

Source: [Page title](page_url)

> Description (if there is any)

ArtStation profile: https://profile_url

RSS Feed: https://profile_url.rss
