displays squiggly using the specified color.

Details and Options

Examples

open all close all

Basic Examples  (3)

Display text with a red squiggly underline:

Wolfram Language code: Squiggled["text"]

Use a green squiggly underline:

Wolfram Language code: Squiggled["text", Green]

Squiggle text in a list:

Wolfram Language code: Squiggled[{x, y, z}]

Squiggle a single element of a list:

Wolfram Language code: {x, y, Squiggled[z]}

Scope  (4)

Squiggle text in any expression:

Wolfram Language code: Squiggled[Integrate[1 / (x ^ 3 + 1), {x, 0, 1}], Orange]

By default, the typeset form of Squiggled[expr] evaluates to itself:

Wolfram Language code: Squiggled["four"]
Wolfram Language code: "four"//InputForm

This can be changed using the option StripOnInput:

Wolfram Language code: Squiggled["four", StripOnInput -> True]
Wolfram Language code: "four"//InputForm

Squiggle text within graphics:

Wolfram Language code: Graphics[{Disk[], Text[Squiggled["bob", Green], {1, 1}]}]

Squiggle text within Graphics3D:

Wolfram Language code: Graphics3D[{Sphere[], Text[Squiggled[x ^ 2 + y ^ 2 + z ^ 2 < 1, Black], {0, 0, 0}]}]

Options  (9)

Background  (1)

Specify a background color to use:

Wolfram Language code: Squiggled["text", Background -> StandardGray]

FontColor  (2)

Specify a font color to use:

Wolfram Language code: Squiggled["text", FontColor -> Brown]

Combine emphasis with custom background and font color specifications:

Wolfram Language code: Squiggled[x ^ 2 + 1 + "bob", Cyan, Background -> StandardGray, FontColor -> White]

FontFamily  (1)

Specify a font family to use:

Wolfram Language code: Squiggled["text", FontFamily -> "Helvetica"]

FontSize  (1)

Specify a font size to use:

Wolfram Language code: Squiggled["text", FontSize -> 20]

FontSlant  (1)

Use italics within the squiggled expression:

Wolfram Language code: Squiggled["text", FontSlant -> Italic]

FontWeight  (1)

Specify a font weight to use:

Wolfram Language code: Squiggled["text", FontWeight -> Bold]

StripOnInput  (2)

Create a squiggled output that evaluates to the first argument of Squiggled:

Wolfram Language code: Squiggled[Defer[1 + 2], StripOnInput -> True]

When the output is used as input, the Squiggled wrapper disappears:

Wolfram Language code: Hold[1 + 2]

When the hold is released, evaluation proceeds normally:

Wolfram Language code: ReleaseHold[%]

An explicit setting StripOnInput False is preserved when the output is used as input:

Wolfram Language code: Squiggled[x + y, StripOnInput -> False]
Wolfram Language code: x + y//InputForm

Applications  (3)

Squiggle words that do not appear in the spelling dictionaries:

Wolfram Language code: If[!DictionaryWordQ[#], Squiggled[#], #]& /@ TextWords[ExampleData[{"Text", "TheRaven"}]][[ ;; 150]]

Squiggle snowfall totals from Buffalo that fall outside one standard deviation of the mean snowfall:

Wolfram Language code: {mean, sd} = Through[{Mean, StandardDeviation}[ExampleData[{"Statistics", "BuffaloSnow"}]]]
Wolfram Language code: If[!Between[#, {mean - sd, mean + sd}], Squiggled[#, Orange], #]& /@ ExampleData[{"Statistics", "BuffaloSnow"}]

Create an integral in which the integrand is squiggled:

Wolfram Language code: Integrate[Squiggled[Cos[x], StripOnInput -> True], x]

The output can be used as input to evaluate the integral:

Wolfram Language code: ∫Cos[x]ⅆx

Properties & Relations  (1)

Highlighted provides an alternative highlighting idiom:

Wolfram Language code: {Squiggled[x], Highlighted[x]}

Possible Issues  (2)

Invalid color specifications will typeset without a squiggle:

Wolfram Language code: Squiggled[foo, bar]

Squiggled may not propagate to text nested within other typeset expressions, such as Graphics:

Wolfram Language code: Squiggled[Graphics[Text["foo"]]]

Wrap Squiggled tightly around the expression to format to avoid this:

Wolfram Language code: Graphics[Text[Squiggled["foo"]]]
