RSyntaxTextArea is a customizable syntax highlighting text editor component for Java Swing applications, supporting 50+ languages, code folding, and search/replace. It is a drop-in JTextComponent subclass with add-on libraries for code completion and spell checking.

Use cases

• add syntax highlighting to a Java Swing text editor
• build a code editor in Java with code folding
• embed a code editing component in a desktop Java application
• highlight 50+ programming languages in a Swing UI
• add search and replace to a Swing text component
• extend syntax highlighting to custom languages with JFlex

When to choose

• you are building a Java Swing desktop application that needs code editing
• you want a mature, BSD-licensed syntax highlighting component on Maven Central
• you need code folding, completion, or spell checking add-ons in Swing

When to avoid

• you are building a web-based editor (use CodeMirror or Monaco)
• your application is not Java/Swing
• you need a full standalone IDE rather than an embeddable component
