Module:Emoji

Module documentationviewedithistorypurge

Module:Emoji implements two functions:

emocode

Takes one unnamed parameter, the name of the emoji, and returns the hex code for the corresponding emoji. If no name is supplied it uses "smiley" as the default (and returns 1f603).

emoname

Takes one unnamed parameter, the hex code of the emoji, and returns the name for the corresponding emoji. If no name is supplied it uses "1f603" as the default (and returns smiley). Emoji names are taken from the Unicode standard's CLDR Short Name, replacing spaces with underscores.

It stores the mapping from name to code in Module:Emoji/data, which internally generates the reverse lookup table from code to name.

Examples

• {{#invoke:Emoji | emocode | wink}} → 1f609
• {{#invoke:Emoji | emocode | grin}} → 1f601
• {{#invoke:Emoji | emocode | 8ball}} → 1f3b1
• {{#invoke:Emoji | emocode }} → 1f603
• {{#invoke:Emoji | emoname | 1f62b}} → tired_face
• {{#invoke:Emoji | emoname }} → smiley

return the hexadecimal code associated with an emoji's name

	{{#invoke:Emoji|emocode|smiley}} → 1f603

When the specified name does not exist in the data table, returns the unrecognized name

If a name is not provided, returns  'smiley' (1f603)

--[[--------------------------< E M O N A M E >----------------------------------------------------------------

return the emoji's name associated with a particular hexadecimal code

	{{#invoke:Emoji|emoname|1f603}} → smiley

When the specified hexadecimal code does not exist in the data table, returns the unrecognized code

If a hexadecimal code is not provided, returns  '1f603' (smiley)
