/**
|
|
|
|
* EmojiInput - augmented inputs for emoji and autocomplete support in inputs
|
|
|
|
* without having to give up the comfort of <input/> and <textarea/> elements
|
|
|
|
*
|
|
|
|
* Intended usage is:
|
2019-06-18 19:13:03 +00:00
|
|
|
* <EmojiInput v-model="something">
|
2019-06-10 15:57:53 +00:00
|
|
|
* <input v-model="something"/>
|
2019-06-18 18:30:35 +00:00
|
|
|
* </EmojiInput>
|
2019-06-10 15:57:53 +00:00
|
|
|
*
|
|
|
|
* Works only with <input> and <textarea>. Intended to use with only one nested
|
|
|
|
* input. It will find first input or textarea and work with that, multiple
|
|
|
|
* nested children not tested. You HAVE TO duplicate v-model for both
|
|
|
|
* <emoji-input> and <input>/<textarea> otherwise it will not work.
|
|
|
|
*
|
|
|
|
* Be prepared for CSS troubles though because it still wraps component in a div
|
|
|
|
* while TRYING to make it look like nothing happened, but it could break stuff.

/* Using a bit more smart approach to padding emojis with spaces:
|
|
|
|
* - put a space before cursor if there isn't one already, unless we
|
|
|
|
* are at the beginning of post or in spam mode
|
|
|
|
* - put a space after emoji if there isn't one already unless we are
|
|
|
|
* in spam mode
|
|
|
|
*
|
|
|
|
* The idea is that when you put a cursor somewhere in between sentence
|
|
|
|
* inserting just ' :emoji: ' will add more spaces to post which might
|
|
|
|
* break the flow/spacing, as well as the case where user ends sentence
|
|
|
|
* with a space before adding emoji.
|
|
|
|
*
|
|
|
|
* Spam mode is intended for creating multi-part emojis and overall spamming
|
|
|
