## Quick Start
#### RichTextState
Use `RichTextEditor` composable to create a rich text editor.
The `RichTextEditor` composable requires a `RichTextState` to manage the editor's state.
To create a `RichTextState`, use the `rememberRichTextState` function:
```kotlin
val state = rememberRichTextState()
RichTextEditor(
state = state,
)
```
#### Styling Spans
To style spans, `RichTextState` provides `toggleSpanStyle` method:
```kotlin
// Toggle a span style.
richTextState.toggleSpanStyle(SpanStyle(fontWeight = FontWeight.Bold))
```
To get the current span style of the selection, use `RichTextState.currentSpanStyle`:
```kotlin
// Get the current span style.
val currentSpanStyle = richTextState.currentSpanStyle
val isBold = currentSpanStyle.fontWeight = FontWeight.Bold
```
#### Styling Paragraphs
To style paragraphs, `RichTextState` provides `toggleParagraphStyle` method:
```kotlin
// Toggle a paragraph style.
richTextState.toggleParagraphStyle(ParagraphStyle(textAlign = TextAlign.Center))
```
To get the current paragraph style of the selection, use `RichTextState.currentParagraphStyle`:
```kotlin
// Get the current paragraph style.
val currentParagraphStyle = richTextState.currentParagraphStyle
val isCentered = currentParagraphStyle.textAlign = TextAlign.Center
```
#### Add links
To add links, `RichTextState` provides `addLink` method:
```kotlin
// Add link after selection.
richTextState.addLink(
text = "Compose Rich Editor",
url = "https://github.com/MohamedRejeb/Compose-Rich-Editor"
)
```
To get if the current selection is a link, use `RichTextState.isLink`:
```kotlin
// Get if the current selection is a link.
val isLink = richTextState.isLink
```
By default, links will be opened by your platform's `UriHandler`, if however you want to
handle the links on your own, you can override the composition local as such:
```kotlin
val myUriHandler by remember {
mutableStateOf(object : UriHandler {
override fun openUri(uri: String) {
// Handle the clicked link however you want
}
})
}
CompositionLocalProvider(LocalUriHandler provides myUriHandler) {
RichText( ... )
}
```
#### Add Code Blocks
To add code blocks, `RichTextState` provides `toggleCodeSpan` method:
```kotlin
// Toggle code span.
richTextState.toggleCodeSpan()
```
To get if the current selection is a code block, use `RichTextState.isCodeSpan`:
```kotlin
// Get if the current selection is a code span.
val isCodeSpan = richTextState.isCodeSpan
```
#### Ordered and Unordered Lists
You can add ordered and unordered lists using `RichTextState`:
```kotlin
// Toggle ordered list.
richTextState.toggleOrderedList()
// Toggle unordered list.
richTextState.toggleUnorderedList()
```
You can get if the current selection is an ordered or unordered list, using `RichTextState`:
```kotlin
// Get if the current selection is an ordered list.
val isOrderedList = richTextState.isOrderedList
// Get if the current selection is an unordered list.
val isUnorderedList = richTextState.isUnorderedList
```
#### Customizing the rich text configuration
Some of the rich text editor's features can be customized, such as the color of the links and the code blocks.
```kotlin
richTextState.config.linkColor = Color.Blue
richTextState.config.linkTextDecoration = TextDecoration.Underline
richTextState.config.codeSpanColor = Color.Yellow
richTextState.config.codeSpanBackgroundColor = Color.Transparent
richTextState.config.codeSpanStrokeColor = Color.LightGray
```
#### HTML import and export
To convert HTML to `RichTextState`, use `RichTextState.setHtml` method:
```kotlin
val html = "
Compose Rich Editor
"
richTextState.setHtml(html)
```
To convert `RichTextState` to HTML, use `RichTextState.toHtml` method:
```kotlin
val html = richTextState.toHtml()
```
#### Markdown import and export
To convert Markdown to `RichTextState`, use `RichTextState.setMarkdown` method:
```kotlin
val markdown = "**Compose** *Rich* Editor"
richTextState.setMarkdown(markdown)
```
To convert `RichTextState` to Markdown, use `RichTextState.toMarkdown` method:
```kotlin
val markdown = richTextState.toMarkdown()
```
