Improved Export to PDF​

We have reworked our exporter once more to make it possible to print large notebooks or render expressions within a bulky notebook. Now, our renderer won't try to rasterize hidden elements and waste resources on them.

Improved GUI of Manipulate​

We have improved the layout, as well as added Copy Expression and Copy Parameters options to assist

Minor formatting improvements​

AlgebraicNumber​

ToNumberField[(*SqB[*)Sqrt[2](*]SqB*), (*SpB[*)Power[2(*|*),(*|*)1/4](*]SpB*)]
(*VB[*)(AlgebraicNumber[Root[-2 + #1^4 & , 2, 0], {0, 0, 1, 0}])(*,*)(*"1:eJxTTMoPSmNkYGAoZgESHvk5KWlMIB4vkAjLTC13SU3OL0osyS8KBskH5eeXFJ2xrk+bt+CbPQCNIhCc"*)(*]VB*)

New command palette tools!​

including Code Beautifier and String Escaper

(* try to apply on this one *)
(* place your cursor here and run Beautify from the command palette *)

f[ω_, eps_, list_List] := eps + Total @ Table[((Power[i[[2]],2])/(Power[i[[1]],2] - Power[ω,2] + I i[[3]] ω)), {i, list}]

n[ω_, params__] := Sqrt[f[ω, params]] 

r[ω_, L_, params__] :=With[{np = n[ω, params]},Power[Abs[((np - 1)/(np + 1))],2]]

Try Bull Running btw 😉

Tabular support​

  • is one of new features in Wolfram in a long time, that significantly improves dataset workflow.

We added the corresponding representation to WLJS Notebook with lazy loading and progressive rendering:

Tabular[{{1, 2, 3}, {4, 5, 6}}]
(*VB[*)(tabular158)(*,*)(*"1:eJxTTMoPSmNkYGAoZgESHvk5KRCeEJBwK8rPK3HNS3GtSE0uLUlMykkNVgEKJycbGaQapKboJianpOiaGBuk6lomp1rqGiYlJZqYW6QZWxqaAQCbIRZd"*)(*]VB*)

Here is another example

Tabular[{{1, x, Today}, {4, y, Tomorrow}}, {"col1", "col2", "col3"}]
(*VB[*)(tabular164)(*,*)(*"1:eJxTTMoPSmNkYGAoZgESHvk5KRCeEJBwK8rPK3HNS3GtSE0uLUlMykkNVgEKp5qYJRknmyXrGiVamumapKUk61qYWRroJhomGSYnWpqYpxgZAgCLaxXR"*)(*]VB*)
EntityValue[
 EntityClass["Book", "DuneBooks"], {"FirstPublished", "Author", 
  "Image"}, "Tabular"]
(*VB[*)(tabular33)(*,*)(*"1:eJxTTMoPSmNkYGAoZgESHvk5KRCeEJBwK8rPK3HNS3GtSE0uLUlMykkNVgEKJ5kbmqUmJhnomhslJumaGBlY6CYZmyXpmpkZWBibm1taWqSZAACBthUb"*)(*]VB*)

InputTerminal​

We added a new I/O element to our GUI building blocks

t = InputTerminal[]
(*VB[*)(EventObject[<|"StandardInput" -> OutputStream["/private/var/folders/fs/ch7ddlhn7jz5vyg5k8bbrxyh0000gn/T/m000050493621", 7], "StandardError" -> OutputStream["/private/var/folders/fs/ch7ddlhn7jz5vyg5k8bbrxyh0000gn/T/m000051493621", 8], "Id" -> "08892486-275c-4c18-9dbf-3af499c66145", "View" -> "35618a69-6e0e-48b2-9e96-39a440007831"|>])(*,*)(*"1:eJxTTMoPSmNkYGAoZgESHvk5KRCeEJBwK8rPK3HNS3GtSE0uLUlMykkNVgEKG5uaGVokmlnqmqUapOqaWCQZ6VqmWprpGlsmmpgYGBiYWxgbAgB0mhSP"*)(*]VB*)

It uses the same EventObject interface as most GUI element, but allows to interact with default streams

WriteString[t["StandardOutput"], "Hi There!"];
WriteString[t["StandardError"], Sqrt[1/2]];

Here is a basic echo handler you can make using events interface:

EventHandler[t, {"Command" -> Function[c, c]}];

"Evaluate All Cells" Button​

A highly requested feature now is available from the top menu

Better implementation of Information[]​

We reimplemented the output form of Information, try it out:

??Plot

or for multiple symbols

?Log*

OpenerView​

We implemented OpenerView aka spoiler element:

OpenerView[{"Show me a plot", Plot[x, {x,0,1}]}, False]
