[X] My Assistant

I asked Mayriad to make a script for me some time ago, so I thought about sharing it.

By her own words "It gives the count after the "Showing X - X of X images" message if there is at least one GIF".
It also highlights which thumbnails are GIFs.

Description: Highlight GIF thumbnails by border and mention a count.
[gist.github.com] EH Gallery GIF Indicator

I will eventually add it to my master script, but I will add it to the index for now.

Is there a script for double page viewing in mpv? I just want to read manga like they were printed and no more double page splits.

This is impossible since the site cannot determine what pages should be next to each other to look like a correct book. Even if you don't care about the correct pairing of pages, the MPV is complicated and there is no good solution; my master script has an experimental feature for this, but it is random and I made it for fun.

Are there any script that gives you a "random" gallery button on your favorites?? Nhentai have this and its one of the few features I wish we also had here.

A nice random button is impossible if you are talking about favourites, because the gid search Cipher-kun mentioned is not supported there. Only a very dumb solution that saves all links in advance is doable.

How about 1 button to go directly to read-mode without having to go in the gallery and click the first image? I'm asking because some works I'd rather not spoil myself with the first 5 images on the frontpage of the gallery view.

This is also impossible if you want to go straight to the standard single page viewer instead of MPV, because you cannot know the URL of the first page before entering the gallery. However, if you want to go straight to the MPV, my script already has a feature for this.

Does the Tagging Checker script still work?? I installed the newest version posted by that other guy in the thread but It dosen't seem to do anything and the thread is locked

Jump to a random gallery

Didn't want to create a separate thread since this has an external dependency, and it's a pretty hacky implementation.

Requires Meldo-Megimi/EH-Page-Scrobbler (search on github. Can't include links) installed and running (this script fetches a variable set by that one)

This is mostly coded by ChatGPT and held together by hopes and dreams. If there's a better and more efficient script doing something similar, point me toward that

Will not work for the watched page most of the time because there's an upper limit to how far back you can go. if someone knows what that upper limit is, lmk and I can update the script accordingly

I have not tested all edge cases, so this script might do something unexpected. You have been warned

Spamming the button might trigger bot protection

Will not work for the watched page most of the time because there's an upper limit to how far back you can go. if someone knows what that upper limit is, lmk and I can update the script accordingly

Unless I missed a change with some of the recent updates, it should be:
Cut off after ~7 days for most users
No cutoff for gold star donators

Unless I missed a change with some of the recent updates, it should be:
Cut off after ~7 days for most users
No cutoff for gold star donators

Any idea roughly how many galleries are uploaded here per day? That way I can set a max gid range for the watched page to 7 days worth of gids
And is there any way to detect gold star donators? Then I can disable that range limitations for those accounts

Best way would probably just be a checkbox that someone with a gold star can tick?
Else the only way I'm aware of, would be their profile page shows they are in the gold star group (or catgirl which also counts), though that misses at least 2 users.

Re average amount of uploads, that'll vary wildly, esp. around events like comiket, but even just, someone figuring out how to use something like pixivutils, so I dunno if any reliable number could be got. There are date selectors (click Jump/Seek to get those options), you might be able to work out some averages by just entering a date, pressing the < Prev button (which takes you to the start of the date), then doing it again for the same date and pressing the > Next button (which takes you to the end of the date), and just calculating the difference between the gid's, though it'll not be perfectly accurate due to private galleries and updated galleries.

Here's the updated script:

The watched page can now select from up to 52 days in the past. From my testing, if no tags are searched for in the watched history, the entire watch history is available, which is restricted to ~52 days if even one tag is searched. Gold start donators can tick the checkbox to bypass this 52-day restriction in the script

Edit: The limit looks much more complicated. I'm seeing different GID limits for different search terms and profiles

A Script Request:

Some way to mark galleries as read/complete so it's easily visible in search results.
(EDIT: You can mark galleries with ratings (the stars), they change the star colors visible in search. This post contains some CSS for a style extension to make the change more visible.)

I tried [sleazyfork.org] EhxVisited and Mayriads master script but EhxVisited doesn't work in Incognito (doesn't remember/store which was visited) and favorites are needed for the latter to hide galleries.

This script is an example of what I want: [sleazyfork.org] NHentai Improved "Mark as read Feature" which works as intended, in incognito, regardless of account, with no limit.

The goal being to just know what I read, since tagging and rating don't have any visible changes in search and favorite just puts some black bars around date.

Unrelated Request:
A way to quick search for hentai versions of gallery, like all works from search to google (title + "hentai") or to AniDB/MAL.

Thanks for reading and If I missed something let me know.

Re: Site Changelog 2024-10-15

- A test build that adds support for upcoming changes to image and thumbnail handling is now running on the onion site. The changes are mostly internal, but there are some thumbnail-related DOM changes in case people want to check for script compatibility. This will be pushed to the main site in a few days.

If anyone's too lazy to check the onion site (and solve the damn captcha lmao), here's a sample of the old and new thumbnail DOM:

They're also now styled with grids over float

Any chance someone could update the "eze" downloader script for the new website changes? Seems to have finally broken.
I've been using it to download galleries in their compressed formats for years because of the useful info.json it adds to the zip.
The github was last updated it 2019 so I'm not counting on the original dev to update it at this point.
Thanks

You can make these changes and it seems to work. Don't know if other functionality is broken.

Change this line
nodes = n.querySelectorAll(".gdtm");
to this
nodes = n.querySelectorAll("a");


Then look for this block.
Add the n2 = n; line
and add the // to all the lines missing it.

```
else {
// Elements
n2 = n;

// if (
// (n = n.querySelector("div")) !== null &&
// (n2 = n.querySelector("a")) !== null
// ) {
image.url = n2.getAttribute("href") || "";

if ((n2 = n2.querySelector("img")) !== null) {
image.filename = n2.getAttribute("title") || "";
image.index = (parseInt(n2.getAttribute("alt") || "", 10) || 1) - 1;
}

if ((m = re_image_url.exec(n.getAttribute("style") || ""))) {
// Setup image
image.thumbnail = m[3];
image.width = parseInt(m[1], 10);
image.height = parseInt(m[2], 10);
image.x_offset = parseInt(m[4], 10);
}
// }
}
```

Amazing! Works perfectly, thank you so much. I was able to hack together another solution but this is much more convenient.
As far as other features go, I haven't noticed any other problems, yet.

Thanks again!

Made a new version for "Auto fjord changer for Vigs", since the original is not available anymore
I didn't get to see it before it was removed but I assume it's what it was doing, if not, feel free to remove my post.

 auto_fjord_changer_1.1.user.js.txt ( 451bytes ) Number of downloads: 32

Just updated it to make it works on links to a specific page as well.

A Script Request:

Some way to mark galleries as read/complete so it's easily visible in search results.
(EDIT: You can mark galleries with ratings (the stars), they change the star colors visible in search. This post contains some CSS for a style extension to make the change more visible.)

I tried [sleazyfork.org] EhxVisited and Mayriads master script but EhxVisited doesn't work in Incognito (doesn't remember/store which was visited) and favorites are needed for the latter to hide galleries.

This script is an example of what I want: [sleazyfork.org] NHentai Improved "Mark as read Feature" which works as intended, in incognito, regardless of account, with no limit.

The goal being to just know what I read, since tagging and rating don't have any visible changes in search and favorite just puts some black bars around date.

Unrelated Request:
A way to quick search for hentai versions of gallery, like all works from search to google (title + "hentai") or to AniDB/MAL.

Thanks for reading and If I missed something let me know.

Sorry but what do you mean with "... EhxVisited doesn't work in Incognito (doesn't remember/store which was visited) and favorites are needed for the latter to hide galleries"

I tried EhxVisited and it remembers which gallery i have opened during a session, highlighting them on the search page with the color that can be set in the settings.
Even the funtion for hide galleries work, you only need to press the red X in the search page for hide a gallery.

If you want a buttons inside a gallery for toggle "Mark as read"<->"Mark as unread" or a rectagle over the gallery with written "READ" as the scripts "NHentai Improved" should be simple, but that has nothing to do with the incognito mode.
On the other hand the script will not remember, and will not have to remember, the visited or hidden between two separate Incognito sessions.
(N.B. When you close all incognito tabs ad open a new incognito tab it's a new Incognito session).

So I don't quite understand what do you mean. Can you elaborate?

I've created a user script for MPV to try to switch the display mode from vertical to horizontal.
It might still have some issues, but I think it works quite well.
