## What it is
StringTemplate 4 (ST) is a Java template engine for generating source code, web pages, emails, or any other formatted text output, with ports for other languages. It strictly enforces model-view separation and is particularly well suited to multi-targeted code generators, site skins, and internationalization/localization.

## Use cases
- generate source code from templates in a code generator
- render web pages or emails from templates
- build multi-site skins with shared templates
- internationalize and localize formatted text output
- power the output layer of an ANTLR-based tool

## When to choose
- you need strict enforcement of model-view separation in templates
- you are building a multi-target code generator
- you want a mature, battle-tested Java template engine

## When to avoid
- you need a full-featured web templating layer with rich logic and helpers
- you want a template engine outside the JVM ecosystem without a port
- you need actively evolving features; development is slow and maintenance-focused

## Facets
- artifact type: library
- maturity: stable
- function: templating
- domain: web-development, developer-tools, documentation
- platform: jvm, cross-platform
- tags: template-engine, model-view-separation, code-generator, internationalization, antlr, code-generation
