Trillium Notes

github.com/zadam/trilium.

Tree based organization at last. Infinitely deep.

Amazing WYSIWYG, including maths and tables, plus insane plugins like canvas mode, and specific file formats like code/mermaid diagrams/drawing mode.

Version history with automatic snapshots at intervals. TODO how is it implemented? Do they just ZIP multiple versions?

No multiuser features. Except for that, could have been a good starting point of an online multiuser thing such as OurBigBook.com!

With Book Notes it is possible possible to see more than one page at a time on the output, whic his a major feature of OurBigBook. But does it show on HTML export as well?

You can static HTML export any subtree by right clicking on it in the navigation tree.

Is there a CLI to export to HTML? github.com/zadam/trilium/issues/3012

HTML export keeps all data as HTML is their native format. This may be inherited from CKEditor. The files are mostly visible, but there is some CSS missing, it is not 100% like editor, notably math is broken. There is also a hosted way of exposing: github.com/zadam/trilium/wiki/Sharing.

trilium.rocks however has a very good export, it is just a question of how much they had to hacked things, source at: github.com/zerebos/trilium.rocks

The default tHTML export uses frame navigation, with a toc fixed on the left frame. Efficient, but not of this century.

There is no concept of user created unique text IDs: you can have the same headers in the same folders in the UI. It's not even a matter of scopes. On exports they are differentiated as 1_name, 2_name, etc.

Markdown export warns:

Architecture: runs on local SQLite database via better-sqlite3. Data apparently stored in SQLite database at ~/.local/share/trilium-data, no raw files.

Markup is stored as HTML as seen from: sqlite3 document.db 'SELECT * from note_contents'. HTML is their native storage format, quite interesting. But this means it is not source centric, so any source editing would have to go via import/export. It can be done apparently: github.com/zadam/trilium/wiki/Markdown but involves shoving a ZIP around.

WYSIWYG based on ckeditor.com/ which is a dependency. It is kind of cool that the view in which you view the output is exactly the same as the one you edit in, and there is no intermediate format, just the HTML.

Math is KaTeX based.

It also runs on the browser via a server: github.com/zadam/trilium/wiki/Server-installation. And they have a paid service for it at: trilium.cc/. Quite impressive.

They have server to from desktop sync: github.com/zadam/trilium/wiki/synchronization. There is no conflict resolution, one of them wins randomly. But they have revision history, and anything lost will be in the revision history. They have so many features it is mind blowing.

Maintainer announced he would be slowing down development since January 2024: github.com/zadam/trilium/issues/4620?ref=selfh.st
