        JavaFileObject file = source.getFile();
        if (file instanceof CeylonFileObject && diagnostic.getType() == DiagnosticType.ERROR) {
            ((CeylonFileObject) file).addError(diagnostic);
        }
    }
    super.report(diagnostic);
}

Example 2 with DiagnosticSource

use of com.sun.tools.javac.util.DiagnosticSource in project error-prone by google.

the class ErrorProneError method formatMessage.

private static String formatMessage(String checkName, JavaFileObject file, DiagnosticPosition pos, Throwable cause) {
    DiagnosticSource source = new DiagnosticSource(file, /*log=*/
    null);
    int column = source.getColumnNumber(pos.getStartPosition(), /*expandTabs=*/
    true);
    int line = source.getLineNumber(pos.getStartPosition());
    String snippet = source.getLine(pos.getStartPosition());
    StringBuilder sb = new StringBuilder();
    sb.append(String.format("\n%s:%d: %s: An exception was thrown by Error Prone: %s\n", source.getFile().getName(), line, checkName, cause.getMessage()));
    sb.append(snippet).append('\n');
    if (column > 0) {
        sb.append(Strings.repeat(" ", column - 1));
    }
    sb.append("^\n");
    return sb.toString();
}

Example 3 with DiagnosticSource

use of com.sun.tools.javac.util.DiagnosticSource in project ceylon-compiler by ceylon.

the class StatementTransformer method getSourceCode.

/**
     * Gets the source code corresponding to the given node
     */
private String getSourceCode(Node node) {
    StringBuilder sb = new StringBuilder();
    DiagnosticSource source = new DiagnosticSource(gen().getFileObject(), Log.instance(gen().getContext()));
    int startLine = node.getToken().getLine();
    int endLine = node.getEndToken().getLine();
    for (int lineNumber = startLine; lineNumber <= endLine; lineNumber++) {
        int startPos = gen().getMap().getPosition(lineNumber, 1);
        String line = source.getLine(startPos);
        if (lineNumber == endLine) {
            line = line.substring(0, node.getEndToken().getCharPositionInLine() + node.getEndToken().getText().length());
        }
        if (lineNumber == startLine) {
            line = line.substring(node.getToken().getCharPositionInLine());
