BookStack VS TiddlyWiki

Depending on what you're attempting to do, there might be possibilities in using the logical theme system or maybe the visual theme system but it would probably take some real hackery.

I use BookStack in my organisation. It meets your requirements (a), (b) and partially (c). It supports LDAP but no Nextcloud integration.

After that, get an instance of bookstack going, set it up to authenticate against your domain, set it up right the FIRST time. And then start documenting everything as you go. Set up a GOOD structure for your documentation FIRST, do NOT do this after the fact, as you are likely to kick it like a can down the road constantly.

If you haven't already, take a look at BookStack.

BookStack - Long term note storage

For context on PDF export I referenced this github issue a few times: https://github.com/BookStackApp/BookStack/issues/3087

https://tiddlywiki.com/ has a search too and more options for saves.

I'd like to recommend Tiddlywiki. Happy to help you long-term with your goals too.

Thank you. I work hard on it. Each member of the house has their own, and it helps us understand each other. My [[Root Users]], [[chameleon]] [https://wiki.waifu.hause/] and [[Sphygmus]] [https://sphygm.us] have gorgeous Tiddlywikis. One HTML file, self-hosted, private unless you choose to share from your machine. If you ever have an interest in making one, you let me know. I'll do my best to help.

I do. I have a Pi I run as a server where it runs PiHole, PiVPN (Wireguard), and a personal Node environment. My main use case is to have a system I can SSH into and develop personal projects. This works well because I have a few machines that I can’t develop locally. A work machine that I can mix personal work. An iPad that has no local shell (I use https://blink.sh for this). It works fantastically!

I’ve made a home “Are you in a meeting” website that everyone on my WiFi can point their browsers to. I have https://tiddlywiki.com instances running there. It manages my VPN when I’m out of the house. And I block a huge portion of ads when I use it as a DNS server.

Tiddlywiki seems (from a technical perspective) a little bit closer to what you're imagining:

https://tiddlywiki.com/

Sadly it doesn't let you edit WYSIWYG, ie when you click "Edit" it still transforms the page back into monospaced markup script.

Theoretically it should be possible to change that, but I have not looked at the codebase.

If you were to do this from the ground up you would probably:

* Enable .contentEditable on the whole page (or at least sections like )

* Add a floating toolbar for formatting controls (and a save button)

* Do the submit in javascript, so the page doesn't have to fully reload.

* Possibly add a toggle edit button? Or would people be comfy being able to accidentally edit pages whilst reading (as long as they realise they have to hit "save" to make a change). This might ruin some people's navigation key shortcuts in their browser (eg users of Vimium).

For personal or small-team use I could see this being good. For larger teams it would be a nightmare, as accidental edits would be common. The formal 3/4 step editing process has its problems, but it's a useful barrier against the tides.

There are a couple of "single file" solutions in existence, but they have incredibly specific use cases...Like the EPUB format, and the TiddlyWiki project. At the end of the day, it likely just boils down to "There's no demand nor foreseeable need for such a format." Sure, use cases could be contrived and built towards, but it's a solution looking for a problem at the moment.
