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() ``` Check out Compose Rich Editor's [full documentation](https://mohamedrejeb.github.io/Compose-Rich-Editor/) for more details. ## Web live demo You can try out the web demo [here](https://compose-richeditor.netlify.app/). ## Contribution If you've found an error in this sample, please file an issue.Feel free to help out by sending a pull request :heart:.
