SVG Support & MathJax #351

Closed Abourass closed 2 years ago

Abourass commented 5 years ago

I have been absolutely adoring my time with Trillium, however, when making notes on the math behind coupling (software eng), I found out that Trillium doesn't support SVG! If you've ever been a wiki page that has mathematical functions, they are svg generated using the MathJax Library. If it's possible to integrate SVG support (and maybe one day the ability to generate SVG for mathematical functions), I would be eternally grateful.

Alright, so I just realized that since they are black in font, and I was using the dark theme, they did paste in correctly, so SVG do work, I apologize. I set figures to have their background color be white (by setting them to black since dark mode inverts). Going to keep this open for MathJax support though.

Some kind of math support is definitely high up on priority list, but the problem is right now there's no good way to implement it (at least without a lot of time commitment).

The way I'd like to have this done is to be able to insert math content into a standard text note via something like equation editor where you'd put latex or something - something like this actually: https://ckeditor.com/cke4/addon/mathjax There's no such addon for CKEditor 5 yet and it's not something I can afford doing myself so I'm kind of waiting until somebody will do it ...

I was using ckeditor here at my job for rich-text in our main application until I switched to Summernote (mostly due to not using most of CK's features and it having a large footprint), however, I think I could probably do that in my spare time. I'll take a look at what it would take to create said add on.

zadam commented 5 years ago

That would be great! Actually a long time ago Trilium used Summernote but it had a bunch of problems. I'm now very happy with CKEditor 5 - it seem to be very well engineered. The only issue is that the ecosystem around is still pretty small ...

Abourass commented 5 years ago

Totally understandable. From what I can tell, summernote doesn't seem like it would take to poking around with it's internals too well. We just use it for people writing reports (kinda resume style) so basic is fine. CKeditor 5 was really nice though. I just got off work, so I will start work on the CK addon right now. As a quick aside, any thoughts on QuillJS? https://quilljs.com/

zadam commented 5 years ago

I consider QuillJS and similar ProseMirror to be quality projects based on similar ideas (e.g. all of them have data model independent from DOM) as CKEditor 5 and actually implementing them sooner. The reason I chose CKEditor is because there's a company dedicated to that product with good track record and there's better chance of a rich ecosystem while the other two seem to be significantly smaller.

There is https://github.com/isaul32/ckeditor5-math which supports both KaTeX and MathJax as typesetting engines.

zadam commented 4 years ago

@hannesfrank wow, that looks very good!

I will take a closer look.

Any updates about the math support? I am not familiar with node.js and javascript, but I managed to add math support using https://github.com/isaul32/ckeditor5-math & katex and it seems to work. image https://github.com/jdw1023/trilium/commit/eb50f137cfa7956bfb6b7aeae7c25043b079526a https://github.com/jdw1023/ckeditor5-balloon-block-editor-math/commit/090c54bd8624818705686ec568bfc878490c2805

Hi, I'm keeping an eye on this plugin - it seems really promising. The only (smallish) concern is that it's an unofficial plugin and it's a question for the future how it will be maintained.

But otherwise yeah, I do plan to integrate it ...

Hi there I am a new user to trilium. I was interested in maths notes. I found a work around with https://jsbin.com/fegeferile/edit?html,output You can just put the html in a code note and reder note mix, and then include it in any note. As you can see I am no hacker so I was wondering if this could be made from the server side (https://www.mathjax.org/#gettingstarted) so I would not have to work so much :-) About add-ons for ckeditor there is wiris, mathtype, that produces mathml and latex (I think) but it works on a rather expensive subscription system, I think. I hope this is not too stupid o vanal for as I said, I know nothing about programming.

zadam commented 2 years ago

math support has been added a while ago.
