## Why Compose Rich Editor? | ||
Compose Rich Editor is a rich text editor library for both Jetpack Compose and Compose Multiplatform, fully customizable and supports the common rich text editor features. It's built on top of `TextField` and it's going to help you to create a rich text editor easily. <br> | ||
|
||
## Including in your project | ||
[![Maven Central](https://img.shields.io/maven-central/v/com.mohamedrejeb.richeditor/richeditor-compose)](https://search.maven.org/search?q=g:%22com.mohamedrejeb.richeditor%22%20AND%20a:%22richeditor-compose%22) | ||
|
||
### Gradle | ||
Add the dependency below to your **module**'s `build.gradle.kts` or `build.gradle` file: | ||
|
||
```gradle | ||
dependencies { | ||
implementation("com.mohamedrejeb.richeditor:richeditor-compose:$version") | ||
} | ||
``` | ||
|
||
## How to Use | ||
Compose Rich Editor supports both Jetpack Compose and Compose Multiplatform projects,. | ||
|
||
### Create Rich Text Editor with Compose UI | ||
We can easily use Compose Rich Editor by calling the `RichTextEditor` Composable and pass a `RichTextValue`. | ||
|
||
```kotlin | ||
var richTextValue by remember { mutableStateOf(RichTextValue()) } | ||
|
||
RichTextEditor( | ||
value = richTextValue, | ||
onValueChange = { | ||
richTextValue = it | ||
}, | ||
) | ||
``` | ||
> **Note**: You may notice that it's similar to `TextField`, it's because `RichTextEditor`is built on top of `TextField` and it's available with 5 composables: | ||
> - `BasicRichTextEditor` | ||
> - `RichTextEditor` (material2) | ||
> - `OutlinedRichTextEditor` (material2) | ||
> - `RichTextEditor` (material3) | ||
> - `OutlinedRichTextEditor` (material3) | ||
> All `RichTextEditor` composables are fully customisable with same parameters that are available for a normal `TextField`` | ||
> - `TextFieldColors` | ||
> - `Shape` | ||
> - `enabled` | ||
> - `keyboardOptions` | ||
> - `keyboardActions` | ||
> - ... | ||
### Update Rich Text Styles | ||
We have some available methods under `RichTextValue` to update styles. If we use `addStyle` method, we add a style. If we use `removeStyle` method, we remove a style. Also, we can toggle a style using `toggleStyle` methond and all of these methods accepts a `RichTextStyle`as a parameter. <br> | ||
|
||
```kotlin | ||
var richTextValue by remember { mutableStateOf(RichTextValue()) } | ||
|
||
IconButton( | ||
onClick = { | ||
richTextValue = richTextValue.toggleStyle(RichTextStyle.Bold) | ||
} | ||
) { | ||
Icon( | ||
imageVector = Icons.Outlined.FormatBold, | ||
contentDescription = "Bold" | ||
) | ||
} | ||
``` | ||
|
||
The added styles are going to be applied to the written text in the `RichTextEditor`. Also you can get the current styles using `richTextValue.currentStyles`, you may need it to check if a certain style is added. <br> | ||
|
||
```kotlin | ||
var richTextValue by remember { mutableStateOf(RichTextValue()) } | ||
|
||
IconButton( | ||
onClick = { | ||
richTextValue = richTextValue.toggleStyle(RichTextStyle.Bold) | ||
} | ||
) { | ||
Icon( | ||
imageVector = Icons.Outlined.FormatBold, | ||
contentDescription = "Bold", | ||
modifier = Modifier | ||
// Mark the icon with a background color is the style is selected | ||
.background( | ||
color = if (richTextValue.currentStyles.contains(RichTextStyle.Bold)) { | ||
Color.Blue | ||
} else { | ||
Color.Transparent | ||
} | ||
) | ||
) | ||
} | ||
``` | ||
|
||
> **Note**: You can add and remove the styles easily, so you can build your own custom styles panel. Take a look on the sample to know more about creating your own styles panel. | ||
### Available Rich Text Styles | ||
There are some available styles that you can use with `RichTextEditor` and you can create your own custom styles: <br> | ||
|
||
#### Bold | ||
We can add bold style to the text using `RichTextStyle.Bold` style. | ||
|
||
```kotlin | ||
richTextValue = richTextValue.addStyle(RichTextStyle.Bold) | ||
``` | ||
|
||
#### Italic | ||
We can add italic style to the text using `RichTextStyle.Italic` style. | ||
|
||
```kotlin | ||
richTextValue = richTextValue.addStyle(RichTextStyle.Italic) | ||
``` | ||
|
||
#### Underline | ||
We can add underline style to the text using `RichTextStyle.Underline` style. | ||
|
||
```kotlin | ||
richTextValue = richTextValue.addStyle(RichTextStyle.Underline) | ||
``` | ||
|
||
#### Strikethrough | ||
We can add strikethrough style to the text using `RichTextStyle.Strikethrough` style. | ||
|
||
```kotlin | ||
richTextValue = richTextValue.addStyle(RichTextStyle.Strikethrough) | ||
``` | ||
|
||
#### TextColor | ||
We can add text color style to the text using `RichTextStyle.TextColor` style. | ||
|
||
```kotlin | ||
richTextValue = richTextValue.addStyle(RichTextStyle.TextColor(Color.Red)) | ||
``` | ||
|
||
#### BackgroundColor | ||
We can add background color style to the text using `RichTextStyle.BackgroundColor` style. | ||
|
||
```kotlin | ||
richTextValue = richTextValue.addStyle(RichTextStyle.BackgroundColor(Color.Red)) | ||
``` | ||
|
||
#### FontSize | ||
We can add font size style to the text using `RichTextStyle.FontSize` style. | ||
|
||
```kotlin | ||
richTextValue = richTextValue.addStyle(RichTextStyle.FontSize(20.sp)) | ||
``` | ||
|
||
#### Create a custom style | ||
We can create a custom style with implementing `RichTextStyle` interface. | ||
|
||
```kotlin | ||
data class FirstCustomStyle( | ||
val color: Color, | ||
val background: Color | ||
) : RichTextStyle { | ||
override fun toSpan(): Any { | ||
return SpanStyle( | ||
color = color, | ||
background = background | ||
) | ||
} | ||
} | ||
|
||
richTextValue = richTextValue.addStyle(FirstCustomStyle(Color.Red, Color.Blue)) | ||
|
||
object SecondCustomStyle : RichTextStyle { | ||
override fun toSpan(): Any { | ||
return SpanStyle( | ||
color = Color.White, | ||
background = Color.Blue, | ||
fontSize = 20.sp, | ||
fontWeight = FontWeight.Bold, | ||
textDecoration = TextDecoration.Underline | ||
) | ||
} | ||
} | ||
|
||
richTextValue = richTextValue.addStyle(SecondCustomStyle) | ||
``` | ||
|
||
