Example 1 with INodeModelFormatter

use of org.eclipse.xtext.formatting.INodeModelFormatter in project xtext-core by eclipse.

the class AnotherFormatterTest method loadModel.

@Test

    INodeModelFormatter formatter = getInjector().getInstance(INodeModelFormatter.class);

    Root root = parseHelper.parse(Joiner.on(System.lineSeparator()).join(lines));
    Assert.assertNotNull(root);
    EList<Resource.Diagnostic> errors = root.eResource().getErrors();
    Assert.assertTrue("Unexpected errors: " + Joiner.on(", ").join(errors), errors.isEmpty());
    ICompositeNode rootNode = ((XtextResource) root.eResource()).getParseResult().getRootNode();
    ArrayList<String> expectedLines = Lists.newArrayList("test sample {", "", "// just a comment", "}");
    String expected = Joiner.on(System.lineSeparator()).join(expectedLines);
    INodeModelFormatter.IFormattedRegion formattedRegion = formatter.format(rootNode, rootNode.getTotalOffset(), rootNode.getTotalLength());
    Assert.assertEquals(expected, formattedRegion.getFormattedText());
    formattedRegion = formatter.format(rootNode, rootNode.getTotalOffset(), rootNode.getTotalLength());
