// Grab all images and image links - create simple html list of links - insert list at top of page.
// My apologies to anyone reading this; it is a hot mess. But published beats perfect.
// Aha: there IS multi-splitting, using regexes as the delimiter. E.g. "Hello awesome, world!".split(/[\s,]+/); for splittong on spaces and commas.
// Stop scraping. Use document object model.
// Try to find videos, too, like http://www.pornhub.com/view_video.php?viewkey=1098897412 - the mp4's in the source, but not linked except for subscribers
// Imgur does some stupid crap with fake loading / unloading. That'd be fine for memory's sake - but the links also disappear. DownThemAll breaks and this only lists presently-onscreen images.
// Images are still under "content" inside <meta property="og:image"> tags.
// Tempted to just split(http) and filter for URLs with image-filetype extensions.
// List Pixiv links because 'select -> open all in tabs' doesn't work anymore. (Eventually fix in Smoothener.)
// Consider setting custom colors, at least for visited links. (Done.)
// Added NewGrounds because their gallery view is sort of terrible.
// For text files: document.body.innerHTML = document.body.innerHTML.split( /[\n ]/ ).filter( s => s.match( '//' ) ).map( s => '<a href=' + s + '>' + s + '</a><br>' )
// Support MP4s.
// I'm considering getting rid of the link whitelist. Linking all image still goes first, and has purpose - but why not support all ordered links in gallery-like sites?
// This thought leads back to old considerations of scraping all my various subscription pages on multiple websites. With text links, it's tractable.
// The main obstacle, then as now, is domain origin policy. It -should- help that a script for this could run on each of those domains.
// Hide visited links? display:none does not work. Neither does visibility:hidden. Uh... huh.
// https://stackoverflow.com/questions/20074015/a-visited-img-display-none - fuck's sake. "For privacy reasons," it's broken on purpose.
// So there's probably no workaround like unlinking those links. Anything that could tell the site which other sites you've visited is a vulnerability. Shoot.
// 'Open unvisited links' would serve the same purpose.
// booru.org
// Highlight MP4s. Give them a special class or some shit.
// This occasionally gets 'script running too long' errors... and on weird sites. Like DuckDuckGo. Which is bizarre, since I don't think it runs anything at all until triggered. Even then there's no live HTML collection left spinning away. They get Array.from'd in a hurry.
// Menuless access a la Gallery Swallower: insert a DOM element in the upper-left corner, thin enough it won't interfere with sensible website design. When clicked it changes classes. Put an interval in this script to check the length of a live HTML collection containing that class. When it's nonzero, clear the interval and show_links().
// Ideally this is a button that slides out or has on-hover text indicating what the hell it does. It'll be useless on a touchscreen, but come on.
// I commented on HFand "Link all images" appeared in my comment text. The button appeared in the comment iframe and I shrugged it off. This is cause to add //@noframes, obviously, but more importantly it makes me wonder what the fuck HF's comment code is doing and whether that's a vulnerability.
// Given the appearance, consider releasing as "Eza's Scraping Notch." But then Universal Scraper is more descriptive.

. direct image links from 'eza's universal scraper' are so great on sites like Mastodon. no lag. no endless loading. I want that to work on pixiv, which is all lag and loading, because they use lazy js for fucking everything.
