Hevelius Sky Culture lacks json file

[diegorodriguezperegrin]

This wonderful sky culture used to be present in previous versions of Stellarium. Now it disappearead. So I downloaded the popular version by Mark Crossley from (https://stellarium.org/lv/skycultures-list.html) and unzip it into user's directory sky cultures. But it doesn't show up in Stellarium afterwards. Inspecting the log file, I discovered:

2.738][CRIT] Failed to find /index.json file in sky culture directory "hevelius"

So, it seems that this "hevelius" folder may be sort of outdated since it doesn't come with any json file that seems necessary from most recent versions.

Now, creating one from scratch does not seem easy. Is there any updated version?

Please read the introduction of chapter 9 of the User Guide, and then section 9.3.

Thank you! Now I have run the skyculture - converter tool on hevelius folder and found many issues. Luckily, not a single showstopper though, since the original culture is only containing constellation art, so most warnings were just ignored or corrected (constellation abbreviations with constellation names, special characters). All in all, Hevelius now works again in Stellarium, with 74 illustrations, just as in the original folder.

The only missing point is that, when all the cultures are listed in Stellarium Sky Culture, this folder appears as "# Hevelius". Why is that? How can I make it listed just as the other cultures, no "#" in front of its name?

For convenience, I have included the conversion log, and the new convertered Hevelius folder, including the json file hevelius.zip.

Many thanks for your hard and excellent work!

I mean that Stellarium doesn't seem to like jumps in levels. It doesn't like going directly to ##, and neither going from # to ###.

Right. It doesn't like breaking of the structure where there's level-1 SC name, level-2 fixed section name (see User Guide section 9.1), and then any level subsections.

The problem appears more related to jumps not the structure itself. Anyway, according to User Guide section 9.1, I also upgraded Constellations and Author from level 3 to 2. Maybe a refined conversion tool may reduce any manual intervention on old "official" sky cultures, but at the end of the day is not that big deal. Many thanks for all the insights!

The extra downloads are just "not the official ones" which are part of the installation. No converter can foresee all possible hickups that were tolerated in the old format. Fortunately, after conversion, any manual fixup usually takes just minutes.

[diegorodriguezperegrin]

Yes, fortunately. But at least, the ones listed in https://stellarium.org/lv/skycultures-list.html should be good to be ready to install.
