Generates wikitext to render the a clickable button. Renders the button component from the Codex design system for Wikimedia. Includes helper functions for URL parsing and cleaning, adding tracking categories. Intended for use in templates and other modules. Implements Template:Clickable button and others. Supports legacy parameters.

• Options to include an icon from the list in Template:Clickable button/styles.css
• Create an icon-only or a dummy button (no target link/URL)
• Target a URL or a wikilink
• Set the weight, size and state of the button (enabled or disabled).

---

• It has two CSS files. Template:Clickable button/base.css is required and makes minor tweaks for word-wrapping if the visible label is too long, centering or aligning button left or right, and minimum widths as is needed for icon-only buttons and labels two characters or less.
• The second CSS file, Template:Clickable button/styles.css, is prepended to the button's HTML only if an icon is used.

Usage in wikitext

Input is case-insensitive.

{{#invoke:Clickable button|main
| 1       = <!-- Alias for wikilink -->
| 2       = <!-- Alias for label -->
| label   = <!-- Button label -->
| link    = <!-- Wikilink -->
| url     = <!-- URL -->
<!-- Inputs are case-insensitive -->
| action  = <!-- progressive | destructive | default: default. -->
| weight  = <!-- primary | quiet | default: normal. -->
| size    = <!-- small | large | default: medium. Automatically chooses size based on line-height and device. -->
| icon    = <!-- Per stored icon-list in [[Template:Clickable button/styles.css]] e.g., search  -->
| aria-label = <!-- [[w:ARIA]] label for accessibility DOM tree. -->
| nocat      = <!-- `true` to not auto-categorize. -->
| category   = <!-- Category name e.g., [[Category:Name]] or Category:Name or just Name -->
}}

Usage in other modules

Ensure you know what to expect from the function you are calling.

• function main emits a TemplateStyles call and pre-processes the arguments with Module:Arguments first, e.g. ignore blank values ''.
• function _main Parses the arguments to account for use of legacy parameters and decides whether aria-disabled should be true.
• The module's other functions, such as _renderLinkData and renderLink, are localised and would need to be made global first to be accessible to other modules.

To call main for example, use:

local createButton = require( 'Module:Clickable button/sandbox' )
buttonWikitext = createButton.main( {
    link = 'South Africa',
    label = 'Go to South Africa',
    action = 'progressive'
    weight = 'quiet',
    size = 'medium',
    icon = 'link',
    disabled = true
} )
return buttonWikitext

which generates wikitext such the value of buttonWikitext would be:

<templatestyles src="Template:Clickable button/styles.css" /><templatestyles src="Template:Clickable button/icons.css" /><span class="cdx-button cdx-button--fake-button cdx-button--action-progressive cdx-button--weight-quiet cdx-button--size-medium  cdx-button--fake-button--disabled" role="button" aria-disabled="true"><span class="cdx-button__icon cdx-demo-css-icon--link" aria-hidden="true"></span>Go to South Africa</span> [[Category:Pages using disabled dummy button]]

Function _main would output:

<span class="cdx-button cdx-button--fake-button cdx-button--action-progressive cdx-button--weight-quiet cdx-button--size-medium  cdx-button--fake-button--disabled" role="button" aria-disabled="true"><span class="cdx-button__icon cdx-demo-css-icon--link" aria-hidden="true"></span>Go to South Africa</span> [[Category:Pages using disabled dummy button]]

And as a result, unless a templatestyle is added to give the class an icon, the icon would not render.
