Usage

From source file:com.google.devtools.build.lib.packages.util.SubincludePreprocessor.java

@Override
public Preprocessor.Result preprocess(Path buildFilePath, byte[] buildFileBytes, String packageName,
        Globber globber, Set<String> ruleNames) throws IOException, InterruptedException {
    StoredEventHandler eventHandler = new StoredEventHandler();
    char content[] = FileSystemUtils.convertFromLatin1(buildFileBytes);
    while (true) {
        Matcher matcher = SUBINCLUDE_REGEX.matcher(CharBuffer.wrap(content));
        if (!matcher.find()) {
            break;
        }//ww  w. j  a  v a 2s  . c o  m
        String name = matcher.group(1);
        String path = resolveSubinclude(name);

        char subContent[];
        if (path.isEmpty()) {
            // This location is not correct, but will do for testing purposes.
            eventHandler.handle(Event.error(Location.fromFile(buildFilePath),
                    "Cannot find subincluded file \'" + name + "\'"));
            // Emit a mocksubinclude(), so we know to preprocess again if the file becomes
            // visible. We cannot fail the preprocess here, as it would drop the content.
            subContent = new char[0];
        } else {
            // TODO(bazel-team): figure out the correct behavior for a non-existent file from an
            // existent package.
            subContent = FileSystemUtils.readContentAsLatin1(fileSystem.getPath(path));
        }

        String mock = "\nmocksubinclude('" + name + "', '" + path + "')\n";

        content = Chars.concat(Arrays.copyOf(content, matcher.start()), mock.toCharArray(), subContent,
                Arrays.copyOfRange(content, matcher.end(), content.length));
    }

    if (Chars.indexOf(content, TRANSIENT_ERROR.toCharArray()) >= 0) {
        throw new IOException("transient error requested in " + buildFilePath.asFragment());
    }

    return Preprocessor.Result.success(ParserInputSource.create(content, buildFilePath.asFragment()),
            eventHandler.hasErrors(), eventHandler.getEvents());
}
