Wolfram Language

Github repo

When you open an editor and start typing, the following happens

  1. each character is send to a server and updates the cell (autosaving)
  2. editor tries to figure out the language or a cell type
  3. considering (2) it changes the highlighting and autocomplete / other plugins

In this sense your input cell is an ultimate tool.

tip

To specify the type of a cell - use a prefix in the first line of the cell

.md
# Hello

it can be anything **.** the behavior is defined by language processors shipped via packages installed

Think about it if it was an anonymous file

Then whatever you typed, you should press Shift-Enter to make magic happens.

info

Input cell is a universal text-field and cannot be customized. Output cells can be different and customized via plugins / packages.

Wolfram Language cells support code with built-in syntax highlighting, graphics or any other interactive objects, syntax sugar (fractions) and etc.

Syntax highlighting​

Depending on the language you specify at the first line, it will highlight HTML, Markdown or Javascript. Wolfram Language autocomplete and highlighting can be extended using external packages.

Once you define something in Wolfram Kernel session, the corresponding symbol will appear in the autocomplete window.

Syntax sugar​

All equations typed in the editor are compatible with any WL parser, i.e. can be used in wolframscript, since the syntax sugar and the structure is localized inside comments

For example

2π\sqrt{2\pi} becomes

(*SqB[*)Sqrt[2\[Pi]](*]SqB*)

which is safe for copying to anywhere outside the WLJS ecosystem

The following shortcuts are used for equations typing

  • Ctrl-2 - place a square root on the selected text
  • Ctrl-/ - make a fraction
  • Ctrl-- - make a subscript
  • Ctrl-6 - make a superscript (power)

You can also make your own custom representation of your symbol like in Mathematica using MakeBoxes. Please see InterpretationBox, Interpretation and MakeBoxes and ArrangeSummaryBox, ViewBox, BoxBox

Autoupload files​

Drag and drop a file to the editor
