Installation & Configuration
Pebble is hosted in the Maven Central Repository. Simply add the following dependency into your
<dependency> <groupId>io.pebbletemplates</groupId> <artifactId>pebble</artifactId> <version>3.1.0</version> </dependency>
Also, snapshots of the master branch are deployed automatically with each successful commit. Instead of Maven Central, use the Sonatype snapshots repository at:
You can add the repository in your pom.xml
<repositories> <repository> <id>sonatype-public</id> <name>Sonatype Public</name> <url>https://oss.sonatype.org/content/groups/public</url> <snapshots> <enabled>true</enabled> </snapshots> </repository> </repositories>
If you are integrating Pebble with Spring MVC, read this guide.
You will want to begin by creating a
PebbleEngine which is responsible for coordinating the retrieval and
compilation of your templates:
PebbleEngine engine = new PebbleEngine.Builder().build();
And now, with your new
PebbleEngine instance you can start compiling templates:
PebbleTemplate compiledTemplate = engine.getTemplate("templateName");
Finally, simply provide your compiled template with a
Writer object and a Map of variables to get your output!
Writer writer = new StringWriter(); Map<String, Object> context = new HashMap<>(); context.put("name", "Mitchell"); compiledTemplate.evaluate(writer, context); String output = writer.toString();
PebbleEngineBuilder will also accept a
Loader implementation as an argument. A loader is responsible for
finding your templates.
Pebble ships with the following loader implementations:
ClasspathLoader: Uses a classloader to search the current classpath.
FileLoader: Finds templates using a filesystem path.
ServletLoader: Uses a servlet context to find the template. This is the recommended loader for use within an application server but is not enabled by default.
StringLoader: Considers the name of the template to be the contents of the template.
DelegatingLoader: Delegates responsibility to a collection of children loaders.
If you do not provide a custom Loader, Pebble will use an instance of the
DelegatingLoader by default.
This delegating loader will use a
ClasspathLoader and a
FileLoader behind the scenes to find your templates.
