Directivas especificas de gvsig.org

Note

En construcción

Falta incluir ejemplos y una breve descripción de cada directiva.

En el proyecto gvSIG, se han elaborado algunas directivas que pueden resultar de utilidad en la confección de la documentación. Las más usadas son:

  • include-document.

    Esta directiva permite invocar un documento para que sea incluido en el documento en el que se invoca la directiva.

    La sintaxis de la directiva es

    .. include-document:: ruta-de-la-pagina-a-incluir
       :formato:
    

    El formato es opcional, si no se indica nada se entiende que debe renderizarse como 'rest'.

    Ejemplo

    .. include-document:: ./documentacion-adicional
       :rest:
    

Contenido incluido

Podemos encontrar documentacion adicional sobre ReStructuredText en:

Fin contenido incluido

  • code-block

    Esta directiva permite "colorear" el código fuente que sigue a la directiva. La sintaxis es la siguiente

    .. code-block:: languaje
    
       My code goes here.
    

    Por ejemplo si nuestro código es python:

    .. code-block:: python
    
       class Test:
       
         def TestFunction(self):
           pass
    

Se vería así

class Test:

  def TestFunction(self):
     pass

Esta directiva también permite que se muestren los números de línea del código.

.. code-block:: python
  :linenos:

  """
      The Pygments reStructuredText directive
      ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  
      This fragment is a Docutils_ 0.4 directive that renders source code
      (to HTML only, currently) via Pygments.
  
      To use it, adjust the options below and copy the code into a module
      that you import on initialization.  The code then automatically
      registers the ``code-block`` directive that you can use instead of
      normal code blocks like this::
  
          .. code-block:: python
  
              My code goes here.
  
      If you want to have different code styles, e.g. one with line numbers
      and one without, add formatters with their names in the VARIANTS dict
      below.  You can invoke them instead of the DEFAULT one by using a
      directive option::
  
          .. code-block:: python
              :linenos:
  
              My code goes here.
  
      Look at the `directive documentation`_ to get all the gory details.
