emoji plugin

Support for conveniently working with Unicode emoji in Zsh.


This plugin provides support for working with Unicode emoji characters in zsh using human-readable identifiers. It provides global variables which map emoji names to the actual characters, country names to their flags, and some named groupings of emoji. It also provides associated functions for displaying them.


Variable Description
$emoji Maps emoji names to characters
$emoji_flags Maps country names to flag characters (using region indicators)
$emoji_groups Named groups of emoji. Keys are group names; values are whitespace-separated lists of character names

You may define new emoji groups at run time by modifying $emoji_groups. The special group name all is reserved for use by the plugin. You should not modify $emoji or $emoji_flags.


Function Description
random_emoji Prints a random emoji character
display_emoji Displays emoji, along with their names

Usage and Examples

To output a specific emoji, use:

$> echo $emoji[<name>]


$> echo $emoji[mouse_face]

To output a random emoji, use:

$> random_emoji

To output a random emoji from a particular group, use:

$> random_emoji <group>


$> random_emoji fruits
$> random_emoji animals
$> random_emoji vehicles
$> random_emoji faces

The defined group names can be found with echo ${(k)emoji_groups}.

To list all available emoji with their names, use:

$> display_emoji
$> display_emoji fruits
$> display_emoji animals
$> display_emoji vehicles
$> display_emoji faces

To use emoji in a prompt:

PROMPT="$emoji[penguin]  > ""
PROMPT='$(random_emoji fruits)  > '
PROMPT="$surfer  > "

Technical Details

The emoji names and codes are sourced from Unicode Technical Report #51, which provides information on emoji support in Unicode. It can be found at

The group definitions are added by this OMZ plugin. They are not based on external definitions. (As far as I can tell. -apjanke)

The values in the $emoji* maps are the emoji characters themselves, not escape sequences or other forms that require interpretation. They can be used in any context and do not require escape sequence support from commands like echo or print.

The emoji in the main $emoji map are standalone character sequences which can all be output on their own, without worrying about combining characters. The values may actually be multi-code-point sequences, instead of a single code point, and may include combining characters in those sequences. But they're arranged so their effects do not extend beyond that sequence.

The exception to this is the skin tone variation selectors. These are included in the main $emoji map because they can be displayed on their own, as well as used as combining characters. (If they follow a character that is not one of the emoji characters they combine with, they are displayed as color swatches.)

Experimental Features

This defines some additional variables and functions, but these are experimental and subject to change at any time. You shouldn't rely on them being available. They're mostly for the use of emoji plugin developers to help decide what to include in future revisions.


Variable Description
$emoji2 Auxiliary and combining characters
$emoji_skintone Skin tone modifiers (from Unicode 8.0)

Skin Tone Variation Selection

This includes experimental support for the skin tone Variation Selectors introduced with Unicode 8.0, which let you select different skin tones for emoji involving humans.

NOTE: This really is experimental. The skin tone selectors are a relatively new feature and may not be supported by all systems. And the support in this plugin is a work in progress. It may not work in all places. In fact, I haven't gotten it to work anywhere yet. -apjanke

The "variation selectors" are combining characters which change the appearance of the preceding character. A variation selector character can be output immediately following a human emoji to change its skin tone color. You can also output a variation selector on its own to display a color swatch of that skin tone.

The $emoji_skintone associative array maps skin tone IDs to the variation selector characters. To use one, output it immediately following a smiley or other human emoji.

echo "$emoji[smiling_face_with_open_mouth]$emoji_skintone[4]"

Note that $emoji_skintone is an associative array, and its keys are the names of "Fitzpatrick Skin Type" groups, not linear indexes into a normal array. The names are 1_2, 3, 4, 5, and 6. (Types 1 and 2 are combined into a single color.) See the Diversity section in Unicode TR 51 for details.


These are things that could be enhanced in future revisions of the plugin.

  • Incorporate CLDR data for ordering and groupings
  • Short :bracket: style names (from gemoji)
  • Incorporate gemoji data
  • Country codes for flags
  • ZWJ combining function?

Gemoji support

The gemoji project seems to be the de facto main source for short names and other emoji-related metadata that isn't included in the official Unicode reports. (I'm saying this just from looking at the google results for "emoji short names" and related searches. -apjanke)

If this plugin is updated to provide short names, CLDR sorting data, and similar stuff, it should probably be changed to use the Gemoji project, and the script be rewritten in Ruby so it can use the Gemoji library directly instead of parsing its data files.

This does not mean that it should use Gemoji at run time. None of the zsh plugin stuff should call Gemoji or Ruby code. Rather, the "build time" script should be rewritten to use Gemoji to generate a pure-native-zsh character definition file which would be checked in to the repo and can be called by OMZ users without having Gemoji installed.

ZWJ combining function

One of the newer features of Unicode emoji is the ability to use the "Zero-Width Joiner" character to compose multiple emoji characters in to a single "emoji ligature" glyph. For example, this is how Apple supports "family" emoji with various genders and skin tones.

These are a pain to write out (and probably worse to read), and it might be convenient to have a couple functions for concisely composing them, if wider support for them appears.

You can’t perform that action at this time.
