Description

An extended JavaFX TextFlow with custom emoji images which helps you to achieve consistency in your JavaFX cross-platform UI applications displaying emojis along text.

It helps you to parse a plane text with emoji aliases with : around the alias (ex. :smile: ) or unicode emoji symbols to custom emoji images with text
and wraps it in custom EmojiTextFlow that is based on JavaFX TextFlow

See demo GIFs with examples under doc/img

How to use

Example code is in: src/main/java/ExampleJavaFXEmojiTextFlow.java

Dependency gradle local downloaded .jar files:

First you need to get .jar file with EmojiTextFlow from releases, here on github (NOTE: following configuration is from build.gradle of emoji-text-flow-demos/list-emoji-text-flow-local-libs-demo demo project )

1. put your .jar in root libs directory of your javafx project.
2. add/change your build.gradle to have these lines:

repositories {
    mavenCentral()
    flatDir {
        dirs 'libs'
    }
}

dependencies {
    //// MUST INCLUDE THESE DEPENDENCIES START
//    implementation name: 'JavaFXEmojiTextFlow_emojitwo-1.0'
//    implementation name: 'JavaFXEmojiTextFlow_openmoji-1.0'
    implementation name: 'JavaFXEmojiTextFlow_twemoji-1.0'

    // https://mvnrepository.com/artifact/org.sharegov/mjson
    compile group: 'org.sharegov', name: 'mjson', version: '1.3'
    // https://mvnrepository.com/artifact/org.slf4j/slf4j-api
    compile group: 'org.slf4j', name: 'slf4j-api', version: '1.7.25'
    // https://mvnrepository.com/artifact/org.slf4j/slf4j-simple
    compile group: 'org.slf4j', name: 'slf4j-simple', version: '1.7.25'
    //// MUST INCLUDE THESE DEPENDENCIES END
    // ... your other dependencies
}

run this example with:

./gradlew exampleEmojiTextFlowWithListView

How to run example codes

Example of using EmojiTextFlow:

./gradlew exampleEmojiTextFlowWithListView

running example with emojitwo images:

Example real time typing and converting to emoji

./gradlew exampleTypingTextConversion

running example with openmoji images:

Example search emoji by their :name: (ex. :smile:)

WARNING:

There is an old example code from https://github.com/UltimateZero/EmojiOneJava In this example EmojiTextFlow is NOT used.

./gradlew oldExampleEmojiSearch

running example with twemoji images:

Free emoji packs used in this project:

OpenMoji: https://github.com/hfg-gmuend/openmoji

Twemoji: https://github.com/twitter/twemoji

EmojiTwo: https://github.com/EmojiTwo/emojitwo/

you can add your own ...

How to add my own emoji pack and use it instead of default ones?

NOTE: you need to make sure you follow same naming of your emoji .png files as in this project. (See in emoji_images there are all lowercase unicode emoji names for each emoji image file; emoji.json is used to search your files by names.)

1. put your my_awesome_emoji_pack in ./emoji_images next to other packs

2. in settings.gradle give a value to emojiImagesPath variable like this:

WARNING! the name of variable should be the save as your custom emoji pack directory name! In this example both are: my_awesome_emoji_pack

gradle.ext.emojiImagesPath = 'my_awesome_emoji_pack'

3. in terminal run:

./gradlew buildJar

4. grab your custom emoji pack jar of EmojiTextFlow from build/libs and place it to your other project as a dependency

HINT: It is not necessary to have all emoji images in .jar

You can create your own emoji pack with only few of emoji .png images and recompile it by yourself. It will dramatically reduce .jar file size.
