Version 2.3.7 🎂

Minor update of client & frontend

Probably this will the last update for the next 3 months. We rebuilt the GUI of a launcher, fixed hundreds of small bugs and wrote 15 more documentation pages 📒 with examples and refined API for keyboard ⌨️ event listeners in Graphics library

Docs page 📚

An examples folder was restructured and moved to Demos. All notebooks are read-only there, the system will not let to overwrite them :)

As usual you have a choice of two versions

• minimal (no offline installation)
• normal 🍍

👍🏼 Pick up a minimal one if you have an internet connection and no firewalls, it will save up some space. Both versions will work normally offline after installation.

Bugs & features

• #161 Kubuntu & Ubuntu launch problem fixes 🐛
• Shortcuts are supported in browser as well 🪄
• Launcher GUI implemented instead of a console 🪄

• GNU/Linux / MacOS sockets now can handler connection breaks better (no freezes) 🐞
• Graphics`Canvas[] feature. See more here
• Added folder argument to the command line to specify the default home folder (see Readme)
• Keyboard listeners. Now you can bind keys to WL's event system 🪄
• Auto install packages from command palette 🪄
• Introduction to symbolic programming chapter was added 📖

Now we Blog section on the documentation page 🍰 Here we will post some nice example on how we use WLJS in practice.

As a side note

We still have issues running WLJS on Windows from time to time (#162 for example 🪲) and it is not quite reproducible. Please, submit an issue if you face similar problems. It will help a lot us in debugging the problem.

Major update 🎓

Since the total bundle size (app + docs + libs) has exceeded 300 MB, we have decided to provide you with two options:

• WLJS Notebook Minimal: Requires an internet connection for installation and accessing documentation.

• WLJS Notebook Full: Includes offline documentation and the latest libraries.

Bug Fixes & Features Implemented

Plotting & Graphics

Minor update 2

Bug fixes & changes

• Full control over a sidebar
  Now it can be hidden on shown by just clicking the button

• Windows 10/11 title bar fix

• Updates channel
  You can specify a Github repo used for updates

• Improved AI
  Now 3500 tokens of our documentation is sent to OpenAI for each chat session, which improves the quality of answers drastically.

• Better support for Image objects
  Before it was quite buggy

• Missing boxes
  Sometimes Boxes.wl was not loaded properly to an evaluation kernel. We changed the way how it loads.

• New examples
  Animation, realtime raster processing is added.

• Scientific tools
  A new section with useful widgets is added to the examples folder

New snippets

• Format text
  A small toolbar to change the font-size, color used in any cell (quite experimental)

• Take a picture
  Captures a photo using your active web-camera and sends to Wolfram Kernel

Minor update

Some fancy features were added

Highlights

AI Assistant 🪄

A deep integration with OpenAI. Now there is a separate chat-window and AI has an read/write access to the cells in the notebook. It can help you to fix errors, print new cells and so on...

We still haven't tried all possible cases.

SummaryBox partial support 🎁

It appears in many Wolfram's expressions. For example

Bugs and dev features

• minor layout fixes
• camera and microphone permissions fix
• NumericArray support on WLJS Interpreter for best performance
• RevealJS slides markdown directives support (change background and etc)
• PointLight works properly
• new events from slides window (Slide, Left, Mount, Destroy)
• ImageSize and Magnification options for Image
• reset dynamic symbols, when the connection to kernel was lost
• an option to disable acrylic material on Windows 11 machines
• an option to enable JIT Tailwind compiler to use any Tailwind classes in notebook cells (slows down the frontend when enabled)

Code signed release

We are officially signed by Apple!
No problems on Mac M1/M2/M3 with installation are expected.

Minor changes

• code formatter

• show options snippet

• Graphics3D scaling fixes

Major update 🍎

Much wider support of 2D and 3D graphics

Updated primitives and transformations Polygon, Disk, Arrow, Cylinder, GraphicsComplex, Rotate, GeometricTransformation and many more. See Reference

Preview

WebGL accelerated GraphicsComplex dynamics

Preview

All vertices are recalculated by WL Kernel in realtime

ManipulatePlot

An easy dynamic version of Plot built on-top of a default dynamics

New features

• AnimationFrameListener triggers events to match refresh rate of a screen
• ZoomAt programmatically zoom into graph
• TransitionType, TransitionDuration allows to control the interpolation between different states of graphics primitives.
• Emissive new material parameter
• MeshMaterial support for different materials (3D graphics)
• ReadClipboard

PlotlyJS full integration

It allows to fully utilize an official Plotly library using WL. It mimics 1:1 an original API and also supports animations, 3D graphics, diagrams and so on

Preview

trace1 = <|
	"x" -> {1, 2, 3, 4}, 
	"y" -> {10, 15, 13, 17}, 
	"type" -> "line" 
|>;

Plotly[trace1]

or some other examples

data = <|
	"z" -> Table[x y, {x,-10,10}, {y,-10,10}],
	"type" -> "heatmap"
|>;

Plotly[data]

or fast realtime animations

Bidirectional export to HTML

• embed external images from Markdown and Slide cells
• unicode support
• auto-convert from HTML back to a normal notebook format (.WLN)
• embed NotebookStore raw data

UI

• Open in browser feature, that reopens a window using a system internet browser
• Offline docs
• icons update

Documentation

• Both offline / online. Click to Misc or locate from the top-menu
• All implemented expressions are finally documented!
• More examples and tutorials

WLJS Notebook 2.0 is out 🚀

It's been a long time, since the last release came out. WLJS Notebook and all supplementary plugins were rewritten from scratch in order to enforce modularity, to make maintainable code-base and more user-friendly UI.

Apple Silicons users

There might be some troubles with installation. Please see the guide if it is the case

There are some breaking changes in some APIs, which will be reflected soon in our documentation.

Major update 🍪

Client app

• Wolfram Kernel troubleshooting assistant
• Automatic authorization and activation using Wolfram ID and password provided

Frontend

• Improved cursor movement between cells (can jump into the hidden input cell).
• More snippets: code formatting, file uploader.
• More examples.
• More features for editable decorations (try Bra[2] or Ket[-2], for example).

Binaries

• added M1 architecture

The immortal edition 🔌 (minor update)

This covers the case, when there is no internet connection possible (see #57 )
The binaries comes with all packages and plugins necessary for functioning properly. However, if there is internet connection to github.com (where all packages are stored), it will anyway download the latest version.

Other changes

Math input

Now it uses a different way of representing syntax sugar for math input and other decorations

is represented as

(*FB[*)((1)(*,*)/(*,*)((*SqB[*)Sqrt[2](*]SqB*)))(*]FB*)

if you remove comments, it will look like

(1)/(Sqrt[2])

which is safe for using it anywhere keeping the actual code unchanged.

Just to remind the shortcuts

• Ctrl+/ on the selection - make a fraction
• Ctrl+2 make a square root
• Ctrl+6 make a superscript
• Ctrl+- make a subscript

CellPrint

This comes handy when making progress bars and other temporal messages. Please see the reference.

Please also see new examples located from the main menu
