kiwix-tools VS libzim

You're saying the fix is merged in https://github.com/kiwix/kiwix-tools? I looked at the commit history after 3.4.0 and didn't see anything relevant to this. Did I miss it, or is there somewhere else I should be looking?

Not 7Zip, but there are Kiwix Tools that allow you to explore the ZIIM, and of course various readers for different Operating Systems that render article HTML

u/RedditNoobie777, the library is served by a piece of software called Kiwix Serve, and issues with it (which might include what it displays, what it should display) are on this GitHub: https://github.com/kiwix/kiwix-tools/issues . I think before you could help categorize, it would be necessary for the software to be updated to display information like whether an archive is mini or maxi, and the date of the archive. There is an issue for the date: https://github.com/kiwix/kiwix-tools/issues/551 . Displaying the filename on the tile would be a quick solution, as it currently has all the information.

Have you checked https://github.com/kiwix/kiwix-tools/issues ?

thanks for the link. I didn't find this yet but some kiwix-serve repository which I can't find now anymore. Found some related issues there I.e. https://github.com/kiwix/kiwix-tools/issues/518 They mention an option allowing to set the url-path, I left a question there if it was possible to do so with the docker image as well.

Kiwix is an offline reader that allows users to browse entire copies of Wikipedia (ca. 83Gb for the whole thing, incl. images), StackExchange (new release coming up soon), the Gutenberg project, etc. stored locally. The project is fully FOSS (here's the git repo) and the subreddit is r/Kiwix.

I rummaged a bit and found a super old feature request on Sourceforge specifically asking for compatibility with non-JS browsers, including lynx. That would be for Kiwix-serve (which you can find here)

I setup an offline version using Kiwix-serve Tools. Essentially you: Get up to speed here: https://wiki.kiwix.org/wiki/Kiwix-serve Download for example 'wikipedia_en_all_maxi_2021-03.zim' from Here: https://download.kiwix.org/zim/wikipedia/ en = English - all_maxi = all content. Setup a web server using the kiwix-tools for example 'kiwix-tools_win-i686-3.1.2.zip' from here: https://download.kiwix.org/release/kiwix-tools/

I meant the Kiwix dump (https://download.kiwix.org/zim/wikipedia_en_all_nopic.zim – careful, 60GB!).

At a first glance, the Wikimedia XML dump does not look substantially different from what Kiwix/ZIM does with compressed HTML: They're both compressed (bz2 for the Wikimedia dump, zstd or LZMA for Kiwix/ZIM), and both compress multiple files at once, so inter-file redundancy should hopefully be significantly reduced.

HTML seems a bit more verbose than the Mediawiki syntax (plus the XML header for each article), but I'd be surprised if that actually accounted for a 3x difference in size.

Then again, Kiwix seems to have experimented with shared dictionary brotli compression, which supposedly yields an >2x improvement: https://github.com/openzim/libzim/issues/144

I wonder if their current zstd implementation also uses shared dictionaries. If not, that might just be the reason: If ZIM compression chunks are much smaller than the bz2 streams of the Wikimedia dumps, there would still be a lot of redundancy between chunks.

This is low-level stuff, but the new release of the backend that powers Kiwix clients, libzim 8.1.0 (changelog), now targets WebAssembly (a.k.a. WASM). This is big because it potentially brings the full powers of the Kiwix backend to Web apps such as Kiwix JS and Kiwix JS PWA/Electron. Up till now, these apps have relied on a custom JS port of parts of libzim, but it lacked full features, such as Full Text search. So, you will begin to see us integrating new features into the Web versions soon!

I'm doing my part o7

It's seriously a very interesting and useful dataset that you can do a lot of fun stuff with, if you grab one of the zims without pictures it's of very manageable size too of just a few dozen gigabytes compressed, and there are reasonably good library support in many languages.

Last point doesn't go for Java. Only one I could find for that was this <https://github.com/openzim/libzim>, it's antique and extremely poorly optimized and lacks support for newer compression schemes. I have fixed the performance and added support for zstd compression, but not published the code as it's extremely not finished and major features in the original codebase are very broken. I'll get around to sharing the code some day but right now it's basically permanently mid surgery as I've only patched so far as to get it to extract all or specific files. If anyone wants a copy of this code regardless of state, give me a holler.
