@rdohms yes, I know (I wrote those standards). But not in this case. The :: shorthand indicates a code-block in the indented lines after and replaces :: with :. For instance, if you have a sentence like this:
Look what this code does:
.. code-block:: php
// some php code
You should turn it into:
Look what this code does::
// some php code
Those are rendered the same. But if you have a code block without a sentence you shouldn't use this shorthand.

Hi Rafael! This is an excellent note to add for 2.1 - it wasn't previously documented. And actually, the docs above this are leftover from 2.0, where it was much more work (involving a Thanks so much for this addition! If anyone sees that I've made a mistake in my commits, please let me know! |
