WLXForm

A standard form used for representing Wolfram expressions on Slides and in WLX cells.

By the default it applies ToString transformation. The use cases are the same as for StandardForm.

Example

Strings

Try the simples example:

Sym /: MakeBoxes[Sym, f: StandardForm] := MakeBoxes["Hooray", f]

Sym /: MakeBoxes[Sym, f: WLXForm] := MakeBoxes["Didly-Didly", f]

Here is how it looks in the wolfram language cell:

Here it is in markdown cell:

Complex

Depending on where an expression is displayed, one can change its visual representation using MakeBoxes tagset, i.e.

SpecialOne /: MakeBoxes[SpecialOne, StandardForm] := With[{
	o = Graphics[{Red, Disk[]}] 
},
	MakeBoxes[o, StandardForm]
]

SpecialOne /: MakeBoxes[SpecialOne, WLXForm] := With[{
	o = Graphics[{Blue, Disk[]}]
},
	MakeBoxes[o, WLXForm]
]

in the normal Wolfram cell an output looks like
