This repository is a Kotlin Multiplatform (KMP) library collection designed for rendering rich text and Markdown within Compose applications on Android and Desktop. It consists of several modular artifacts: `richtext-ui` (core UI composables), `richtext-markdown` (AST-based rendering), `richtext-commonmark` (CommonMark parser integration), and theme-specific wrappers (`richtext-ui-material`, `richtext-ui-material3`). The architecture relies on a custom Abstract Syntax Tree (AST) representation of Markdown content, which is traversed recursively to emit Compose composables. While the codebase demonstrates strong engineering practices, particularly in handling deep nesting and large documents, the README explicitly warns that the project is experimental, lacks tests, and has an unclear roadmap. This makes it suitable for prototyping or internal tools but potentially risky for production-critical applications without significant validation.
