Building

Pom-first and manifest-first projects cannot be mixed in the same reactor build (source), so we need to separately build org.metaborg.spg.sentence and org.metaborg.spg.sentence.eclipse*:

mvn clean install -f org.metaborg.spg.sentence.shared/pom.xml
mvn clean install -f org.metaborg.spg.sentence/pom.xml
mvn clean install -f org.metaborg.spg.sentence.antlr/pom.xml
mvn clean install -f org.metaborg.spg.sentence.eclipse.externaldeps/pom.xml
mvn clean install -f pom.xml

Testing

Only the org.metaborg.spg.sentence project contains tests. To run the tests:

mvn test -f org.metaborg.spg.sentence/pom.xml
mvn test -f org.metaborg.spg.sentence.antlr/pom.xml

Usage

Make sure you are using the Java parse table generator. This is the case when metaborg.yaml contains the following:

language:
  sdf:
    sdf2table: java

Using org.metaborg.spg.sentence.(sdf|antlr)

The Main class expects as its first and second argument the path to a Spoofax language artifact and the path to a Spoofax project, respectively.

Using org.metaborg.spg.sentence.eclipse*

An update site is generated at org.metaborg.spg.sentence.antlr.eclipse.site/target/site/. This Eclipse plugin contains both the SDF-generator (ambiguity testing) and ANTLR-generator (difference testing). To install the plugin in Eclipse:

1. Help > Install New Software...
2. Work with: the built update site.
3. Check the Spoofax Generator Eclipse Plugin
4. Follow the installation process.

After installing the Eclipse plugin:

1. Select the project in the Package Explorer.
2. Click Spoofax (meta) > SPG > Generate sentences.
3. Choose a maximum term size and maximum number of terms.
4. The generated sentences appear in the Console.

Warning: If you rebuild this project, uninstall the Eclipse plugin, and reinstall the Eclipse plugin, then Eclipse still uses the old (now uninstalled) version. The only solution I have found is to download a fresh Spoofax Eclipse from spoofax.org.

Using org.metaborg.spg.sentence.evaluation

The Main class runs the generator on a predefined list of languages. These projects can be found here. Use download.sh to download these languages. To run the main class:

mvn clean package exec:java
