Omitting Sections

This is a relatively new feature in rst2pdf (added late 2012, according to the blog post), and wasn’t present in the version I had from Ubuntu’s default repositories in Saucy Salamander (version 0.16). I grabbed the latest (version 0.93) though, and this feature works delightfully well.

Here’s a snippet of an rst file:

array_filter
------------

.. class:: description

    Filters elements of an array using a callback function

.. class:: prototype

    array array_filter(array $array ,  [callable $callback ] )

.. class:: params

    **array** - The array to iterate over

.. class:: params

    **callback** - The callback function to use

.. class:: return

    Returns: Returns the filtered array.

To generate this document with all the elements present, I use something like this:

rst2pdf -s lj.style ref.rst -o ref.pdf

The section of the document containing the list of parameters can get a bit long-winded, so I can easily leave out those sections using a command that looks like this:

{
   "outputSpeech":{
      "type":"PlainText",
      "text":"Ready? What is 4 plus 5?"
   },
   "directives":[
      {
         "type":"Dialog.ElicitSlot",
         "slotToElicit":"Number"
      }
   ],
   "shouldEndSession":"false"
}

This generates the same document using the same styles, but omits the sections I named. You can pass more of the same switch to omit as many classes as you need to for your purposes. I’m now using this in all kinds of places, so I thought I’d share!
