Examples with IFacet org.metaborg.core.language.IFacet used on opensource projects

Example 1 with IFacet

use of org.metaborg.core.language.IFacet in project spoofax by metaborg.

the class DialectService method update.

@Override
public Iterable<ILanguageImpl> update(ILanguageImpl base) {
    final Collection<ILanguageImpl> dialects = baseLanguageToDialects.get(base);
    if (dialects.isEmpty()) {
        return dialects;
    }
    logger.debug("Updating base language for {} dialects", dialects.size());
    final Collection<ILanguageImpl> newDialects = Lists.newArrayListWithCapacity(dialects.size());
    for (ILanguageImpl dialect : dialects) {
        final String name = dialect.belongsTo().name();
        final FileObject location = Iterables.get(dialect.components(), 0).location();
        // HACK: assuming single syntax facet
        final IFacet syntaxFacet = dialect.facet(SyntaxFacet.class);
        final ILanguageImpl newDialect;
        try {
            // Add dialect before updating maps, adding can cause an exception; maps should not be updated.
            // Adding reloads the dialect because location is the same, no need to remove old dialect.
            // GTODO: what if id's or version change?
            newDialect = createDialect(name, location, base, syntaxFacet, true, true);
        } catch (IllegalStateException e) {
            final String message = String.format("Error updating dialect %s", name);
            logger.error(message, e);
            continue;

        nameToDialect.put(name, newDialect);

}

Example 2 with IFacet

use of org.metaborg.core.language.IFacet in project spoofax by metaborg.

the class DialectService method createDialect.

private ILanguageImpl createDialect(String name, FileObject location, ILanguageImpl base, IFacet syntaxFacet, boolean replaceIdentification, boolean appendDialectName) {
    final LanguageIdentifier baseId = base.id();
    final String dialectId;
    if (appendDialectName) {
        dialectId = baseId.id + "-Dialect-" + name;
    } else {
        dialectId = baseId.id;
    }
    final LanguageIdentifier id = new LanguageIdentifier(baseId.groupId, dialectId, baseId.version);
    // HACK: use config of first component.
    final ILanguageComponentConfig config = Iterables.get(base.components(), 0).config();
    final ComponentCreationConfig creationConfig = languageService.create(id, location, Iterables2.singleton(new LanguageContributionIdentifier(id, name)), config);
    for (IFacet facet : base.facets()) {
        if (facet instanceof IdentificationFacet && replaceIdentification) {
            creationConfig.addFacet(new IdentificationFacet(new MetaFileIdentifier((IdentificationFacet) facet)));
        } else if (facet instanceof SyntaxFacet || facet instanceof ResourceExtensionFacet) {
        // Ignore
        } else {
            creationConfig.addFacet(facet);
        }
    }
    creationConfig.addFacet(syntaxFacet);
    final ILanguageComponent dialectComponent = languageService.add(creationConfig);
    final ILanguageImpl dialect = Iterables.get(dialectComponent.contributesTo(), 0);
    return dialect;
}
