// Gelbooru is inconsistent about WebMs. Some resolve to images. Others are blank. Dunno which is better, but pick one.

// Still, address videos on Gelbooru. E.g. https://gelbooru.com/index.php?page=post&s=view&id=5614716&tags=rosiekawaii#dnr#&dnr

// Totally doable. So how do I check for a file without just embedding videos? Ugh, might be beyond onload / onerror behavior.
// Orrrr I could check tags. Not reliable. Could be wrong. But would allow a <video> with onerror to fall back to images.
// Better idea: indicate that it's probably a video, and link to the page without #dnr&dnr. Use Eza's Image Glutton, folks.
// Obviously that's the Ugoira solution on Pixiv: "don't." So it should be how I handle Ugoiras now that they're broken-ish.
// Embedding videos is undesirable because it implies linking to them for download.
// This script is already rude on bandwidth - videos would make it a DDOS attack.
// Solution: show thumbnail, not linked. (To avoid DownThemAll grabbing the thumbnail.) I guess link it to the page. Big _new target.
// Other Mastodon instances are many in number and few in users. An @include block would get ridiculous.
// I am alarmingly close to forking this for Mastodon, doing @include *, and testing for e.g. h-cite / h-entry.
// I don't want to @include * in general - this is not a general-purpose script.
// Even a fetch-based version would only be as flexible as Image Glutton.
// ... I've accidentally made this @include * friendly, by exclusively using button_delay_function.
// If it defaulted to false I could use this anywhere, and only specific switch-case / match domains would get better values.
// Or I could skip the interval entirely if button_delay_function remains at a default null.
// (Probably better to do so if gather_items remains at a default null.)
// Baraag makes me want to support video.
// HicceArs?
// Youhate.us? Down.
// https://thehentaiworld.com/tag/romulo-mancin/page/2/ ? Images and manga.
// e-Hentai.
// Does this script replace Eza's Comic Viewer? (Not public yet, sorry.)
// It's certainly better-equipped to handle fetching. e-Hentai doesn't even have thumbnails; it has one big fat index image per gallery.
// DeviantArt? Tried it once, didn't really work. Probably needs a fetch. Even that's not consistent. It is a terrible website.
// Lolibooru? Image Glutton already supports it.

// Well then.
// Might move image count to the controls area.
// Its text already implies "image size" and "image order." But mostly I'm bugged that it doesn't line up with other text.
// Thematically, the image-size controls should probably be blue. Meh. They're distinct enough for not being grey.
// Consistent color is difficult. I want my clearly red and green reload / remove arrows. But there's little indication of which buttons affect a submission, a single image, the whole page, or simply your position on the page. I tried several janky attempts and figured it's best if engineers don't design interfaces. Plain grey with function-indicative color on-hover is just fine. The only buttons colored by default are the image controls, which are labeled... sort of.
// Abandon thoughts of up-arrow on bottom submission remover. It'd conflict with... actually it might perfetly fit what remove-and-advance conveys.
// Maybe the issue here is overloading what 'X' means. No idea what else I'd use for 'nuke submission.'
// It is annoyingly easy to get caught clicking remove-and-advance instead of just 'advance.'
// The button snaps into place under your cursor if you're submission-aligned and hit 'next image.'
// It's a problem mostly because the apparent result is the same - we scroll clean past the removed image.
// Out-of-bounds signalling for page count -might- still be useful for Pixiv. That'd let us skip the thumbnail-try stuff.
// Tumblr? Not a -great- alternative to Eza's Tumblr Scrape, but pretty close to what that script originally wanted.
// I could elide parse_search into links_from_page_number, and eliminate 'var page_number,' but... meh?
// User reports nothing works. Page clears, spinners show up, and loading ceases with the word "Size:" in the corner.
// Immediate thought - is it just Paheal? Gallery SMOOTHERNER interfered with this, by changing the direct image links.
// (Alright, immediate thought was, 'did I leave items=[] uncommented?,' and thankfully the answer is no.)
// Then again that should still show controls. (Either one.) Is this user's plugin throwing a fit about add_size_button?
// Installed Chromium + TamperMonkey to test this.
// http://rule34.paheal.net/post/list/Loup/1 as a good test page. (Example screenshot is obviously Paheal green.)
// Shows all controls, so that can't be that user's issue.
// Shows all three images and all elements... but not in the right places.
// I'm'a bet this is because I used item_id instead of getElementById( 'item_id' ). Alas. It was too clean to be reliable.
// Goddammit I'm going to have to modify this script in TamperMonkey instead of my editor. (Nevermind, ctrl+a / ctrl+c / ctrl+v.)
// Changed all those back to document.getElementById - did not fix the problem. Well, fuck.
// Inspector shows "basket unmodified" spans are inserted directly into the body, below the reloader button. Uh... huh.
// undoable_replace creates that span in body. Which seems bizarre, in retrospect, except it's supposed to get MOVED by undoable_replace.
// So I'm betting TamperMonkey and/or Chrome just does not handle Element.replace correctly. Fuck me sideways.
// Durr, check console. "current.className.contains is not a function." Wow. That's far dumber than I thought.
// Chromium straight-up has not implement String.contains. Oookay, back to .match.
// Although - it does support classList.contains. Less RegEx-y, more DOMTokenList... y.
// Alright, that fixed it. Ironically I can probably go back to thing_id if I want.
// So... is there any chance that solved the user's problem? I couldn't recreate the problem.
// GreasyFork has no information about their browser / extension.
// Apparently they might've been on Rule34.xxx, because for some reason in Chromium it's (1) green and (2) broken.
// Exact same issue.
// To do:
// Put alt/title (onhover) text on size / order buttons?
// Following an argument on Reddit, yeah, do some accessibility stuff.
// -ms-transform is surely deprecated.
// Genuine bugs:
// Dead images and possibly thumbnails take up horizontal space and cause slight movements while loading.
// Spinners don't spin on Baraag. (Might be intractable.)
// It'd be a little funny to set .s1, .s2, .s3 etc. to different fixed rotations. But it'd screw up sites where the CSS works.
// Keyboard controls often can't remove the last image. Eh. (Could give it 100vh of runout.)
// Bottom anchor once again does not extend "dark mode" div to the bottom of the... page? window? There's whitespace, is the point.
// Link text (i.e. submission number, #dnr&dnr) isn't vertically centered with buttons. Not looking forward to fixing that.
// Killing a submission no longer stops new images from loading... god dammit.
// Ah, it's gonna be Pixiv-only, because we use ready_element after removal.
// Also applies on TheHentaiWorld, so fuck me, I guess.
// Fixed that, but now I notice: undoing a removed submission doesn't resume loading images.
// Could re-ready in undoable_replace... but then I'd also have to track image number with it. Fuck.
// addElement doesn't work... on rule34.xxx... in Chromium... with TamperMonkey. For some goddamn reason.
// Tried an earlier version, 2.13.50 - rule34.xxx works fucking fine.
// ScrollIntoView doesn't seem to work on Chromium.
// Changes since last version:
// Edited InkBunny -again- because single images sometimes aren't linked. Why? Go fuck yourself, that's why.
// Golfed that too.
// Golfed InkBunny gather_items to typical_item.
// Testing in Chromium led to using a regex to handle any thumbnail size.
// typical_item now accepts <img> elements for thumb. (Tests typeof, uses thumb.src if 'object'.) Golfed accordingly.
// Similarly golfed away .href where possible.
// Golfed Danbooru to use typical_item. If it's just the link and title for a fetch, why not?
// typical_item no longer requires a thumbnail-to-image function, and will substitute t=>null for fetched sites.
// Set item.fetched, to mark pages when fetching, so reloading the submission will set item.image to null and re-fetch.
// enforce_style's test element, style_check_id, is back to a <div>, because apparently Chromium didn't like br.clientHeight. Shrug.
// Golfed e621 with a better querySelectorAll.
// Golfed booru.org with a better querySelectorAll.
// Minor golf for Ayrion.
// Refactored typical_item to take an <a> element containing some <img>. No more separate thumbnail parameter. DRY.
// Un-refactored all instances of addElement, just for one site, on someone else's browser. Saw keyboard controls still don't work. Stopped caring.
// All I needed to do was swap Element to HTMLElement. Fuck this stack.
