Example 1 with HoverHandler

use of org.eclipse.jdt.ls.core.internal.handlers.HoverHandler in project eclipse.jdt.ls by eclipse.

the class InvisibleProjectBuildSupportTest method testDynamicSourceLookups.

@Test

    assertNotNull(remark);
    // construct hover request
    URI standalone = new File(projectRealPath.toFile(), "UsingRemark.java").toURI();
    String payload = HoverHandlerTest.createHoverRequest(standalone, 2, 3);
    TextDocumentPositionParams position = getParams(payload);
    // perform hover
    HoverHandler handler = new HoverHandler(preferenceManager);
    Hover hover = handler.hover(position, monitor);
    if (hover.getContents().getLeft().size() < 2) {
        JobHelpers.waitForDownloadSourcesJobs(60000);
        waitForBackgroundJobs();
        hover = handler.hover(position, monitor);
    }
    // verify library has source attachment
    remark = JavaProjectHelper.findJarEntry(javaProject, "remark.jar");
    assertNotNull(remark.getSourceAttachmentPath());
    assertNotNull(hover);
    String javadoc = hover.getContents().getLeft().get(1).getLeft();
    assertTrue("Unexpected Javadoc:" + javadoc, javadoc.contains("The class that manages converting HTML to Markdown"));
    // add another artifact to lib folder
    File jsoupFile = DependencyUtil.getArtifact("org.jsoup", "jsoup", "1.9.2", null);
    IPath jsoupCopy = projectRealPath.append("lib/jsoup.jar");
    FileUtils.copyFile(jsoupFile, jsoupCopy.toFile());

    hover = handler.hover(position, monitor);
    if (hover.getContents().getLeft().size() < 2) {
        JobHelpers.waitForDownloadSourcesJobs(60000);
        waitForBackgroundJobs();
        hover = handler.hover(position, monitor);
    }
    // verify original library source attachment persists
    assertNotNull(remark.getSourceAttachmentPath());
    assertNotNull(hover);
    javadoc = hover.getContents().getLeft().get(1).getLeft();
    assertTrue("Unexpected Javadoc:" + javadoc, javadoc.contains("The class that manages converting HTML to Markdown"));
}

Example 2 with HoverHandler

use of org.eclipse.jdt.ls.core.internal.handlers.HoverHandler in project eclipse.jdt.ls by eclipse.

the class SyntaxLanguageServer method hover.

@Override

    logInfo(">> document/hover");
    HoverHandler handler = new HoverHandler(this.preferenceManager);
    return computeAsync((monitor) -> handler.hover(position, monitor));
