;; This package displays emojis in Emacs similar to how Github, Slack etc do. It
|
|||
|
|
;; can display plain ascii like ':)' as well as Github style emojis like ':smile:'
|
|||
|
|
;;
|
|||
|
|
;; It provides a minor mode `emojify-mode' to enable display of emojis in a buffer.
|
|||
|
|
;; To enable emojify mode globally use `global-emojify-mode'

the composition property `prettify-symbol-mode' and `org-bullets' use the

|

This function does two things, first it adds text properties to the completion

|
tooltip to make it display the emojis, secondly it makes company always render
|
|||
|
|
the completion tooltip using `after-string' overlay property rather than
|
|||
|
|
`display' text property.
|
|||
|
|
|
|||
|
|
The second step is needed because emojify displays the emojis using `display'
|
|||
|
|
text property, similarly company-mode in some cases uses `display' overlay
|
|||
|
|
property to render its pop, this results into a `display' property inside
|
|||
|
|
`display' property, however Emacs ignores recursive display text property.
|

Using `after-string' works as well as `display' while allowing the emojis to be

displayed."
