+While reading [Spring AI in Action](https://www.manning.com/books/spring-ai-in-action), I discovered [StringTemplate](https://www.stringtemplate.org).
+
+> StringTemplate is a Java template engine for generating source code, web pages, emails, or any other formatted text output. 
+> StringTemplate is particularly good at code generators, multiple site skins, and internationalization / localization. StringTemplate also powers ANTLR.

+I am thinking of adding support for StringTemplate in [Micronaut Views](https://micronaut-projects.github.io/micronaut-views/latest/guide/). 
+
+```java
+String template = """
+        You are a helpful assistant, answering questions about tabletop games.
+        If you don't know anything about the game or don't know the answer,
+        say "I don't know".
+        
+        The game is {game}.
+        
+        The question is: {question}.""";
+String prompt = new ST(template, '{', '}')
+        .add("game", question.gameTitle())
+        .add("question", question.question())
+        .render();
+```
