This update contains some significant changes, and I recommend creating a backup of your HDoujin Downloader folder before updating, just in case. If you have any problems, let me know, and you can always downgrade to an earlier release here.

Site updates

The bulk of this update is site fixes and support for some new sites, which I’m going to continue working on expanding over the coming days. There are a lot of requests to get through, and I tried to get through as many as possible before releasing this update, but I know that some of you are still waiting.

This release updates cf-tool to version 1.1.0.0, which should hopefully address a lot of the problems that have recently started cropping up in regard to Cloudflare’s browser verification page. This should get a lot of affected sites working again, but if you continue to have problems with any of them, let me know.

Formatting string improvements

I spent a lot of time working on a new parser for formatting strings, allowing you to do some more interesting things with your naming. For example:

• The %IF% token can now be nested, if you feel like dealing with that mess.
• The idea behind the %ARTIST||AUTHOR% token and its counterpart has been expanded upon, and this syntax can now be used with all and with an arbitrary number of tokens (e.g. %ARTIST||AUTHOR||TRANSLATOR||SCANLATOR%).
• Any token that evaluates to a comma-delimited set of values can be limited by providing a limiting argument. For example, %ARTIST(3)% evaluates to at most three artists. This can be combined with the above syntax (e.g. %ARTIST(3)||AUTHOR(3)%).
• An %ID% token has finally been added, which can be used for manga, chapters, and pages, corresponding to the numeric ID that represents the entity (for example, gallery IDs, or image IDs from sites like Pixiv).
• Chapter formatting strings now allow subfolders, so you’re free to use things like %VOLUME#%\%CHAPTER#% to organize chapters by volume.
• The %SUBTITLE% token for chapters has been made more useful, and can do a good job of extracting the subtitle in the majority of cases. This gives you more control over chapter names.
• Tokens are now officially case-insensitive.

There are a couple of other little things I’ll go over when I get to work on the much-needed thorough documentation for this feature. In the meantime, if you have questions, you’re welcome to ask.

When editing your formatting strings, you can now see a little preview about the text box giving you an idea of how it will be evaluated, which should make putting complex strings together a lot easier.

Antivirus false-positives

If you’ve been around for a while, you know this is an ongoing problem that occurs sometimes after releasing major updates (antivirus software really doesn’t like cf-tool). If your antivirus starts harassing you after this update, let me know, so I can submit the corresponding false-positive reports.

This update contains some significant changes, and I recommend creating a backup of your HDoujin Downloader folder before updating, just in case. If you have any problems, let me know, and you can always downgrade to an earlier release here.

New external module system

What makes it significant is that I have (finally) laid the groundwork for an external module system. While the old DIY scripting system was an attempt at this, it was, frankly, a user-unfriendly mess. The new system uses lua, and offers what I believe is a far more comfortable API. You can see an example module here. It shows most of what’s available right now (in addition to a “Log” function for writing things to debug log during testing). In the spirit of getting this update out sooner rather than later, it’s the only example available right now, but I plan to do the majority of work through this system rather than program updates. I am wide-open to suggestions for this feature to help it meet the needs of those wishing to create their own modules.

New repository system

Accompanying this change is a new repository system. Repositories are comprised of a local folder where modules are stored and optionally an online source used for downloading new updates.  The “official” repository is here, and this update comes with it already configured for use. Any updates made here will be transparently synced to HDoujin Downloader, allowing fixes and new modules to be provided in the background without having to update manually. Full program updates are still required to be done through the updater, but having modules separate will make this situation less frequent.

You can access the repositories list under “Tools > Modules”. From here you can disable specific modules and change the priorities of your repositories to prefer certain ones over others (in the case that they both provide modules for a given site). You can also add new ones. Right now, only GitHub folders can by synced, but I’m open to adding more options if anyone has interest in hosting their own repositories elsewhere.

The “Scripts” tab is now obsolete and has been removed. If you’re one of the few people that was actually using that feature, it will be automatically replaced by a repository named “Scripts” that you can access under “Tools > Modules”. Old scripts will continue to work, but it’s not the recommended choice for new development.

Lastly, basic sideways-compatibility for lua modules from other programs has been implemented. Many will not work yet, but some do. This will be improved in future releases. If you use another downloading program that provides modules you’d like to import into HDoujin Downloader, let me know, and I’ll see what I can do.

Site updates

Site updates included in this release are summarized in the changelog. Most notably, sites protected by Cloudflare show now be working again. The fix is provided by “cf-tool” in the “bin” folder, which wraps a Python script for bypassing the verification page. It’s not the ideal solution, but it works, especially in the absence of suitable alternatives for .NET. Let me know if you have any problems with Cloudflare going forward.

Antivirus false-positives

This has been an ongoing issue for the past couple of releases, especially with Windows Defender. Whitelisting sometimes takes a while, making things really inconvenient for early adopters. I’ve done my best to try to avoid this problem with this release as much as possible. If you run into problems in this area, let me know so I can submit the program for whitelisting to the respective AV vendor.

What’s next?

Integrating the repository and external module system was no small feat, and I have done extensive testing to make sure that everything works. I did not expect it to take as long as it did, but now that that hurdle is gone, I can hopefully resume the regular weekly update schedule. There will likely be more updates to address limitations with the current module system’s API as I start moving more sites into it and the requirements become clearer. That’s the plan for now.

As promised, here’s this week’s update. It is primarily a maintenance release, with updates for a bunch of sites, and support for some new ones that have been recently requested.

You might see an error message from the updater after it downloads this update. I noticed a bug in the new updater that slipped through during Release 1 that will cause the message to be shown at the end of the update process, even if nothing actually goes wrong. It can be ignored without a problem, and the updater has been fixed so that it won’t show up next time.

It’s been a while since the last update. For the people still hanging on to Windows XP, you might need to update manually for this one. Update files are now hosted on GitHub, which enforces the use of TLS protocols that .NET Framework 4.0 doesn’t support. You won’t have to worry about this going forward, though, as the improved updater is able to deal with this for future updates.

On the surface, there’s not a whole lot going on with this release. There are a few site fixes (particularly for some higher-profile sites), and support added for sites that quite a few people have asked me about. Little bugs have been fixed here and there (such as being able to save WebP images into PDFs).

The majority of my time with this update was spent on internal rewrites, cleaning things up to make the software easier to maintain going forward. It’s been over 5 years since HDoujin Downloader was first released, and the layers upon layers of patches and updates has started taking its toll on the software’s maintainability. Fortunately, my work on this release has started putting a dent into it. This will allow me to add some new features I’ve been sitting on for a long time that this problem has been holding me back from.

Aside from that, I’ve rewritten the updater, particularly in response to the issues that occurred a while ago. It’s hard to find a reliable file host, and with the way the updater was built, if certain files became inaccessible it would stop working properly and require updates to be carried out manually. It’s now a lot more robust in that regard, capable of pulling updates from a variety of sources in the event one of them stops working.

If you’re one of the many people waiting on a particular request or bug fix, the goal is to get back into regular weekly releases, which will most likely be available every Sunday (this update was scheduled for Sunday as well, but ended up taking a little bit longer). More updates will be available soon as I work through the backlog of requests.

The next big goal is moving site support modules outside of the application, into external scripts where they can be updated and modified more easily. This will allow for faster module updates, especially since it won’t require the entire application to be recompiled just to get a few sites working again. The old scripting system was a step in the right direction, but its execution was too flawed to be truly useful. The next iteration of this feature will be far more usable.

If you have any problems with this release, please report them. If you need to downgrade to the previous release, it will remain available here.

As anticipated in the previous release post, the update to the updater (“updater.exe”) caused the new version to get incorrectly flagged by several antivirus vendors. It’s since been white-listed by all major antivirus vendors, as can be verified by the VirusTotal report. Unfortunately it’s still flagged by several heuristic engines, but there’s little I can do about that.

Of course, the updater is clean– Its behavior just tends to upset heuristic engines (“hey, this can download files!”). As a small-time software developer, this is unfortunately something I have to deal with on the regular, and I thank all of you users of HDoujin Downloader for your understanding!

Unfortunately, Google Drive and Dropbox have temporarily disabled the download links (I’m still waiting for a response from support to get them enabled again). As a result, the updater won’t work properly for the time being, but I expect it to be working normally again within the next couple of days (this is not the first time this has happened).

In the meantime, those that still need to update will need to do so manually (detailed instructions are here). Until this issue is sorted out, the latest release can be downloaded from Mega:

• The updater has been updated

Firstly, this update contains an update to the updater (that’s a mouthful). The update is meant to address an issue some users reported where the update would “finish” partway through and then leave them with a corrupt executable.

The bad news is the updater (“updater.exe”) frequently gets flagged by antivirus software every time I make changes to it, and this time is likely not going to be any exception. If your antivirus software is complaining about the updater, let me know so I can submit a false-positive report.

If you end up having problems and need to downgrade for the time being, Release 309 continues to be accessible here.

• Other things have been updated

As usual, you can check out the changelog to see what’s been done. One of the biggest fixes is related to Cloudflare, which rendered quite a few sites not-working when they updated their browser verification challenge. This release includes a fix for that, and some other Cloudflare-related bugs I came across in the process. It should hopefully be working great for everyone, but if you have any problems, you know the drill: Let me know!

Other than that, there are some fixes for a few sites a lot of users contacted me about, and some other changes that aren’t user-facing (a good deal of refactoring, which this code base has desperately needed).

• Hey! What about my request?

I hear you! Some people have been waiting quite some time to have their requests added to the program, and I get more every day. As many users have probably noticed, I’ve fallen behind with managing to reply to everyone in a timely manner due to some personal circumstances. Rest assured that if you’ve left me a comment, or sent an email I’ve seen it, and I’m wading through them. That said, if you feel like you’ve been waiting for too long, don’t hesitate to check in or send a reminder. I welcome it.

All things considered, this is a relatively minor update. The plan is to kick it into overdrive, get through all the requests, and pump these out on a weekly basis, starting today. Look forward to it!

As is tradition, Release 274 is being flagged by Windows Defender as “Win32/Fuerboos.A!cl”. This is a generic heuristic detection, which means it’s being flagged because it “looks like” something that could potentially be malicious. This is of course a false-positive, and it will hopefully be cleared soon in one of the next definition updates. I’ve already submitted a report to Microsoft, so all we can do now is play the waiting game.

In the meantime, if you’re having trouble running the program, you can add HDoujin Downloader’s folder to your exclusions list. You can find instructions explaining how to do this here. If you had better luck with Release 273 and want to downgrade until Release 274 is whitelisted, you can also download the previous release here.

Since this happens every couple of releases and I’m always flooded with messages asking about it, I’ve made a FAQ page you can also check out with more information about why this happens and how to fix it.

Hello everyone! As some of you are already aware, November has been an especially busy month for me, and early December will follow the same trend.

I have not been able to respond to messages as quickly as usual, but I still read them regularly (so if anything urgent comes up, I can offer a quick fix). If you have been waiting a while for a response, hold out for a little bit longer and I’ll definitely get back to you. Don’t forget you can always use the support forum if you have a question; there are kind users there that know what they’re doing!

On that note, things will start getting back up to speed in about two weeks. You can of course still expect regular site updates (usually each weekend at the latest), but new feature requests are going to be on the back burner for a bit.

This is definitely a stressful time of year; the approaching holiday season is more than welcome. I hope you all get to spend some quality time with your waifus. ♥

With the recent release of Release 261, Avast has started flagging HDoujin Downloader as malicious. This happens every once in a while when the program changes enough that it’s no longer picked up by the whitelist (this is a recurring problem with Avast in particular).

The last update has been submitted for whitelisting. As the developer, I can confirm that this is a false-positive, but if you’d rather wait until it’s cleared, usually they whitelist it within 3 days. Otherwise, you may add the program folder to your exceptions list to prevent it from being deleted.

Overenthusiastic “anti-virus” scanners are the bane of small-time developers.

Update: It has now been whitelisted in Avast’s latest definition update!

Release 247 was uploaded today! You can check out the changelog here.

In addition to adding support for a few new sites and improving/fixing support for others, there have been some heavy changes “under the hood”, specifically involving how the download filter works. On that note, a few annoyances should be solved, and it will work progressively more smoothly in coming updates. If you have any problems with it in this release, let me know.

The updater has been updated as well, and it will now display more information when downloading updates.

However, because of these changes, the signatures of HDoujin and its updater have changed enough to break the white-listing by various antivirus vendors (VirusTotal report here). This has been solved for the most part, but there are still two who have yet to clear it (Baidu, and TrendMicro). If you use either of these programs and find HDoujin has been flagged, don’t worry! it’s a false-positive, and it should be cleared soon.
