## What it is
sora-editor is a multifunctional Android code editor library (also known as CodeEditor) providing incremental syntax highlighting, auto-completion, and many editor features. It is distributed via Maven Central and supports TextMate and TreeSitter grammars.

## Use cases
- embed a code editor in an Android app
- add syntax highlighting to a mobile text editor
- build an Android IDE or code editor app
- implement autocomplete and code snippets on Android
- support TextMate or TreeSitter grammars in an Android editor
- add search, replace, and undo/redo to an Android text view

## When to choose
- you need a feature-rich code editor component inside an Android application
- you want incremental syntax highlighting with TextMate/TreeSitter support
- you need editor features like auto-indent, wordwrap, and diagnostic markers out of the box

## When to avoid
- you need a code editor for desktop, iOS, or web platforms
- you only need plain text editing without code-specific features
- your project cannot use LGPL-2.1 licensed libraries
