I'm a French software engineer, living in the city of Rennes. I'm the founder of SEO4Ajax (seo4ajax.com), and I'm the author of SingleFile and zip.js (github.com/gildas-lormeau).

You can even make the file compatible with ZIP (and PDF) on top of that, see https://github.com/gildas-lormeau/Polyglot-HTML-ZIP-PNG/raw/... (and https://github.com/gildas-lormeau/Polyglot-HTML-ZIP-PNG)
There is a third option:
- Save the page as a self-extracting ZIP file, see https://github.com/gildas-lormeau/Polyglot-HTML-ZIP-PNG
I have an example of a side-project [1] where I think I naturally applied the best practices described in this article. My goal was to see if it's possible to code an entire project using a single agent (Claude).
To do this, I "simply" asked the agent, every time it encountered an issue, how to resolve it, using a validation tool or script. I also asked it to code these tools during audits. As a result, I now have over 30+ rules [2] for validating their commits. It's working pretty well now.

I just ran a test on a 10GB HTML page and called window.stop() via a 100ms setTimeout, which, in my opinion, simulates what would happen in a better-implemented case in SingleFile if the call to window.stop() were made as soon as the HTTP headers of the fetch request are received (i.e. easy fix). And it actually works. It interrupts the loading at approx. 15MB of data, the rendering of the page, and it's partially and smoothly displayed (no freeze). So it's not totally useless but it deserves to be optimized at a minimum in SingleFile, as I indicated. In the end, the MDN documentation is not very clear...
Edit: I've just implemented the "good enough of my machine fix" aka the "easy fix", https://github.com/gildas-lormeau/single-file-core/commit/a0....
Edit #2: I've just understood that "parent" in "this method cannot interrupt its *parent* document's loading" from the MDN doc probably means the "parent" of the frame (when the script is running into it).
The call to window.stop() stops HTML parsing/rendering, which is unnecessary since the script has downloaded the page via HTTP and will decompress it as-is as a binary file (zip.js supports concatenated payloads before and after the zip data). However, in my case, the call to window.stop() is executed asynchronously once the binary has been downloaded, and therefore may be too late. This is probably less effective than in your case with gtwar.
I implemented this in the simplest way possible because if the zip file is read from the filesystem, window.stop() must not be called immediately because the file must be parsed entirely. In my case, it would require slightly more complex logic to call window.stop() as early as possible.
Edit: Maybe it's totally useless though, as documented here [1]: "Because of how scripts are executed, this method cannot interrupt its parent document's loading, but it will stop its images, new windows, and other still-loading objects." (you mentioned it in the article)
[1] https://developer.mozilla.org/en-US/docs/Web/API/Window/stop
Edit #2: Since I didn't know that window.call() was most likely useless in my case, I understand your approach much better now. Thank you very much for clarifying that with your question!
The reason I did not implement the innovative mechanism you describe is because, in my case, all the technical effort was/is focused on reading the archive from the filesystem. No one has suggested it either.
Edit: Actually, SingleFile already calls window.stop() when displaying a zip/html file from HTTP, see https://github.com/gildas-lormeau/single-file-core/blob/22fc...
I haven't looked closely, but I get the impression that this is an implementation detail which is not really related to the format. In this case, a polyglot zip/html file could also interrupt page loading via a window.stop() call and rely on range requests (zip.js supports them) to unzip and display the page. This could also be transparent for the user, depending on whether the file is served via HTTP or not. However, I admit that I haven't implemented this mechanism yet.
I would like to know why ZIP/HTML polyglot format produced by SingleFile [1] and mentioned in the article "achieve static, single, but not efficiency". What's not efficient compared to the gwtar format?
If we were to compare this to the JS world, it seems Python’s async is closer to Babel-style generator-based coroutines [1] than to JavaScript’s async/await execution model.

You haven't got it wrong, the first example in the article behaves the same in JS, see https://jsfiddle.net/L5w2q1p7/.
Thank you also for the kind words! Regardoing support, you can choose whichever method you prefer; it makes no difference to me actually.
Author of SingleFile here. Sorry, this is obviously not normal. Please feel free to report any bugs here https://github.com/gildas-lormeau/SingleFile/issues.
Great idea, some people have already implemented it for the same type of need, it would seem (see the list of user agents in the source code). Implementation seems simple.

FYI, zip.js has no issues with 1 (it can be fixed with standard extra fields), 3 (zip64 support), and 5 (you cannot have more than 64K of comment data at the end of the file).
Unfortunately, I will have difficulty answering your question because my knowledge is limited to the zip format. In the use case presented in the article, I find that the zip format meets the need well. Generally speaking, in the context of long-term archiving, its big advantage is also that there are thousands of implementations for reading/writing zip files.
For implementation in a library, you can use HttpRangeReader [1][2] in zip.js [3] (disclaimer: I am the author). It's a solid feature that has been in the library for about 10 years.

The warning message you mentioned simply means that the extension can inject "content scripts" into the web pages you visit. This feature is necessary, for example, to remove ads that cannot be blocked via HTTP.
Bonus point for clients that don't support the HTTP “Accept-Encoding” header [1] and consume all your bandwidth.

Thank you for explaining your point of view on the interest of this conversation. Here's mine, I consider an offense to be something quite subjective sometimes. In some cases, it's possible to offend someone without meaning to. The solution to this problem is to apologize and offer to talk about it. If that doesn't work, and the offense is in some way "forbidden", then the offended person can simply defend themselves by going to the “authorities”.
I'm sorry. I'm open to discussion if you can explain what is offending to you
I'm sorry if you feel offended. My comments will be removed by HN moderators if they think it's necessary. You can flag and downvote them meanwhile. You can also contact the moderators or your local police if you think it is necessary.
EDIT: It might not be possible to flag or downvote comments. So, I recommend you to contact the moderators or your local police. You can find my name and address on my GitHub profile.
I sincerely apologize again if you found my response offensive. You can contact your local police to make a complaint, I suppose.
Yes, but in this case, there's nothing to stop you from apologizing and possibly discuss the offending point so that it doesn't happen again.
I sincerely apologize if you found my response offensive. It was not my intention and I try to respect the moderation rules on HN. I just wanted to give my point of view, as a person living in the EU.
I'm sorry but it's normal. You don't have the right to offend people online or not.
The UK left EU some years ago.
One doesn't preclude the other, but I have serious doubts about free speech concerns. There are moderate and extreme movements in Europe. They all express themselves freely within the law.
I must admit I'm a little disappointed that the bot isn't able to do this. It would be much more efficient.
No T-spins [1], impressive!
