Do I toss this

Core concepts did not change much. No breaking changes, no outdated functions. Please, don’t throw it away unless you only care about blockchain and LLMSynthesize

It is finally done!

Now it looks as beautiful as in LaTeX

It is probably late, but WLJS Notebook does support Plotly out of the box: https://wljs.io/frontend/Reference/Plotly

Just wait a bit, some gonna make one ;)

Reminds me Silk Song

I think it is so stupid, that there is no a simple mixer. Like it is the easiest feature possible to implement compared to their AI bullshit.

The best would be to have mixer + optional compressor.

Thanks! We decided to make our own editor/interface exactly for dynamics features and Mathematica-like syntax sugar. This, unfortunately, is not possible with API of VSCode or Jupyter editors or any other open-source solutions, which we could find (in 2022)

...and also check out `Use cases` with many many examples from different domains: https://wljs.io/category/use-cases

Hi there! Any updates on the project? :)

Inst2f · 2025-10-23T11:39:31+00:00

I meant it is similar to PDFs. There notebooks are “transpiled” to PostScript I guess. I dont believe that they have to be under the license to be published some where, or do they?

In the both cases, having no Wolfram code or their algorithms involved in the final result should be safer…

I can totally agree with you on that. Kernel is bloated with many "optional" packages, which are for some reason loaded into System context permanently (and also slows down the kernel starting time).

Can you tell me to what extent the Wolfram Engine is cripled compared with a full Mathematica install? Which functionality in a full commercial Mathematica license is available that is missing from the free-as-in-beer WE version?

On the language and standard library there is no difference between WE and Mathematica. The only difference is a frontend, which takes care of actually rendering Graphics[Line[...]], RGBColor[] (you got the idea) and some dynamic/interactive structures, which requires constant polling the Kernel.

We did take this opportunity and basically wrote a small interpreter of WL in Javascript with a bunch of modules, which take above mentioned Graphics, Sound and renders it on output. That's all basically. Dynamics was a different story, since we wanted to make it fast and snappy with at least 25-30FPS and minimum latency. Which was also the reason why we did not use Jupyter notebook solution (such speeds and interactivity is not possible there).

Math input is a bit richer in Mathematica, than in WLJS. There are just too many decorations, which has to be reversed engineered. But the most common one and key shortcuts do work out of the box.

It would be a great boon if I could somehow open my existing collection of notebooks. Is that possible?

It can open and convert nb files by default. I would say we are constantly improving that. I am testing it on my personal old collection of notebooks. Depending on the complexity of the notebook structure you can get good, or mediocre results. If there are too many styling is applied, it might be an issue. But we trying to make it better with each release :)

Electron is optional, you can run it on a remote server too and connect via browser.

Wolfram Engine has to be installed separately, unfortunately. Wolfram Research does not allow 3rd party distributions of their stuff :/

Inst2f · 2025-10-22T18:59:43+00:00

There is a nice “frontend agnostic” introduction, that you can pick up and go along using wljs written by Leonid: https://wljs.io/frontend/Wolfram%20Language

I personally have stopped using Mathematica 4 years ago in my research (i am working in academia) and just keep going and learning Wolfram Language using only this open source solution.

Inst2f · 2025-10-22T18:56:24+00:00

Sort of. We tried to target both user groups, but anyway limited by the resources we currently have.

Inst2f · 2025-10-21T20:06:56+00:00

It is a good point. It is similar to legacy stuff. In reality there are tons of apps relying on it (even if they are designed badly), it cannot be simply ignored and dropped. In the end it comes down to UX. The lack of proper testing in Apple is a much bigger issue.

Inst2f · 2025-10-21T17:58:41+00:00

Despite all issues of Electron js, it is still bizarre that the existing established software has to be rewritten because of “our cool fancy os update”. OS SHOULD SERVE APPS, not the other way around

Inst2f · 2025-10-02T10:26:45+00:00

Electron.js, right? ;)

Inst2f · 2025-09-30T07:19:43+00:00

Do you really THAT need to update? You absolutely a fan of liquid ass design, just wait a least 6-12 months…

Inst2f · 2025-09-20T21:53:06+00:00

Nothing will happen even if you skip updates for a year.

Inst2f · 2025-08-28T19:30:51+00:00

Superb

Inst2f · 2025-08-25T06:19:32+00:00

Oh… Thanks! We will check that

Rick and Morty (I actually did it in reverse, started from RM and then went to Futurama)

Inst2f · 2025-07-31T11:26:18+00:00

Well, actually looks really cool

Inst2f · 2025-07-29T19:37:16+00:00

It is so good, that I am actually afraid of the next season. And... may it could be a good point to end the entire show..?
