Example 1 with Diff

use of gumtree.spoon.diff.Diff in project dspot by STAMP-project.

the class SelectorOnDiff method pathToModifiedJavaFile.

private static Set<String> pathToModifiedJavaFile(String baseSha, String pathToChangedVersion) {
    Process p;
    try {
        p = Runtime.getRuntime().exec("git diff " + baseSha, new String[] {}, new File(pathToChangedVersion));
    } catch (IOException e) {
        throw new RuntimeException(e);
    }
    final Set<String> modifiedJavaFiles = new BufferedReader(new InputStreamReader(p.getInputStream())).lines().filter(line -> line.startsWith("diff") && line.endsWith(".java")).map(line -> line.split(" ")[2]).collect(Collectors.toSet());
    try {
        p.waitFor();
    } catch (InterruptedException e) {
        throw new RuntimeException(e);
    }
    if (Main.verbose) {
        LOGGER.info("Modified files:{}{}", AmplificationHelper.LINE_SEPARATOR, modifiedJavaFiles.stream().collect(Collectors.joining(AmplificationHelper.LINE_SEPARATOR)));
    }
    return modifiedJavaFiles;
}

    try {
        final File file1 = new File(pathFile1);
        final File file2 = new File(pathFile2);
        if (!file1.exists() || !file2.exists()) {
            return Collections.emptySet();
        }
        Diff result = (new AstComparator()).compare(file1, file2);
        return result.getRootOperations().stream().map(operation -> operation.getSrcNode().getParent(CtMethod.class)).collect(Collectors.toSet());
    } catch (Exception ignored) {
        // if something bad happen, we do not care, we go for next file
        return Collections.emptySet();
