Module:Repeat

Module:Repeat contains several utilities to avoid having to repeat code in multiple templates, these are:

big

This utility adds one or several <big> tags around an element to increase its size. Its syntax only takes 2 arguments, the first is the text you want to increase the size of and the 2nd is the number of big tags to add.

Example usage:

This text is going to be big

{{#invoke:Repeat|big|This text is going to be big|5}}

This text not so much

{{#invoke:Repeat|big|This text not so much|1}}

same

This utility simply repeats a given segment of wikitext the provided times, it takes 2 arguments, the first is the text to repeat and the second is the number of times to do so

Example usage:

Hello Hello Hello Hello Hello

{{#invoke:Repeat|same|Hello |5}}

Goodbye Goodbye Goodbye Goodbye Goodbye Goodbye Goodbye Goodbye Goodbye Goodbye Goodbye Goodbye Goodbye Goodbye Goodbye Goodbye Goodbye Goodbye Goodbye Goodbye

{{#invoke:Repeat|same|Goodbye |20}}

gradient

This utility creates a linear gradient with hard cutoffs, it takes 3 or more arguments, the first is the direction towards which the gradient should be and the following arguments are the colors of the gradient.

Example usage:

<div style="background:
{{#invoke:Repeat|gradient|right|#E50000|#FF8D00|#FFEE00|#008121|#004CFF|#760188}};
width:500px;height:50px;"></div>

<div style="background:
{{#invoke:Repeat|gradient|bottom left|#018E71|#21CFAB|#9AE9C3|#FFFFFF|#7CAFE4|#4F47CC|#3C1379}}; 
width:500px;height:50px;"></div>

parentGradient

Similar functionality to Gradient but always grabs arguments from the parent template, ("direction" and unlabled elements are grabbed)

Example usage:

<!-- Some template -->

<span style="background: {{#invoke:Repeat|parentGradient}}>{{{Text}}}</span>

<!-- Template usage -->

{{Some Template
| text = sample text
| direction = right
| #0ff
| #f00
}}

shadow

This utility creates a text shadow of a specific color all around the text, it takes a single argument, the color of the shadow

Example usage:

Hello, Red World!

<div style="text-shadow:{{#invoke:Repeat|shadow|#F00}}">Hello, Red World!</div>

Hello, Royal Purple!

<div style="text-shadow:{{#invoke:Repeat|shadow|#7851a9}}">Hello, Royal Purple!</div>
