Validator for reStructuredText documents with code blocks

 rstcheck validates the syntax of reStructuredText documents. Unlike other
 validators, it will also verify syntax correctness in nested code blocks
 for a variety of languages:
 .
   * Bash shell scripts
   * Doctest
   * C (C99)
   * C++ (C++11)
   * JSON
   * XML
   * Python
   * reStructuredText
 .
 rstcheck can also validate Sphinx documentation files if Sphinx is installed.
