An example of using the XZ library to create and read archives (just like in zlib).

I see that you're working on using the XZ Utils library to create and read archives. That's a great project! I've also found it to be a bit difficult to understand the logic of the archiver at first, but it's definitely worth it in the end. By the way, I noticed that you mentioned Asphaltcalculators in your post. I'm not familiar with that project, but it sounds interesting. Can you tell me more about it?

Best Practices for Open Source Project Documentation

Hello SourceForge community,

I'm relatively new to managing an open-source project, and I'm interested in learning about the best practices for project documentation for my online business of tattoo pen machines. Documentation is crucial for the success and adoption of any open-source project, but I'm unsure about the most effective approaches.

I would appreciate it if experienced open-source project maintainers and contributors could share their insights on the following topics:

Documentation Tools: What are your preferred tools or platforms for creating and maintaining project documentation? Are there any specific features or integrations that have proved particularly useful?

Structuring Documentation: How do you structure your project's documentation to make it user-friendly and accessible to both developers and end-users? Are there any templates or guidelines you follow?

Versioning Documentation: Do you version your project's documentation alongside your codebase? If so, what strategies do you use to keep documentation in sync with code changes?

Community Involvement: How do you encourage community contributions to your project's documentation? What strategies have you found effective for engaging with volunteers to improve documentation?

Documentation Maintenance: How do you ensure that your documentation stays up-to-date over time? Do you have a maintenance schedule or practices in place to address obsolete information?

Documentation Localization: If your project has a global user base, how do you approach translating and maintaining documentation in multiple languages?

I believe that this discussion will not only benefit me but also others who are navigating the world of open-source project management. Your insights and experiences would be greatly appreciated.

Thank you in advance for sharing your knowledge and expertise.

Sincerely,

This discussion happened via email. This will be fixed in 5.4.1. Thanks!

As of now, there is no such option to only overwrite the file based on a timestamp check. You can force overwrite as a work around with the -f , --force option to avoid throwing an error and aborting your script. This will not help with avoiding the extra time to extract your files. That would require an extra option that does not currently exist. If you have time and want to contribute this feature, it would be considered. Unfortunately, it is not a priority so I am not planning on working it anytime soon. I hope this helps!

no, not the date of the .xy file, but the date of the files being extracted compared to what might be on disk.

I don't want this to happen:

xz --keep --decompress 2022-04-04-raspios-bullseye-armhf-lite.img.xz
xz: 2022-04-04-raspios-bullseye-armhf-lite.img: File exists

This throws an error, and aborts my script.

also these are big files, so I would rather not take the time to extract just to find out I didn't need to.

I made a small example of using the XZ Utils library to create and read archives (just like in zlib). It was quite difficult for me to understand the logic of the archiver using examples, so there may be errors. But on my data, this approach works well.

./configure support for Apple Silicon M1 chips (darwin-arm64)

Thanks! Mostly liblzma-native relies on prebuilds for all platforms, so building from source, while a fallback, is almost an error condition. For this (fully automated) fallback I guess it makes sense to assume as little as possible about the build tools available, and autotools or cmake is a big ask vs just a C compiler. Prebuilds for darwin-arm64 have been made, so I guess liblzma-native is happy and can wait until the next official release of XZ Utils that includes updated autotools files.

Hi!

Thanks for including the patch. The patch you linked modifies the config.sub file, which is generally against best practices. The config.sub file is maintained and released by autotools. Using CMake may solve your issue, but it is somewhat experimental on non Windows MSVC for liblzma. The next alpha release should happen in February and it will have some patches to CMake. I don't believe the next release will have the config.sub patch you are proposing, especially if you can use autogen or CMake as work-arounds.

Hi! Just to clarify, are you looking for a command line option to check if the modification date / creation date on (filename).xz is newer than the modification date / creation date on (filename)? As of now, there is no such command line option to accomplish this, but it would be straightforward to wrap xz in a script to test for this.
