title: Sphinx: List of supported languages for highlighting?
body: <p>I'm using Sphinx for code documentation and use several languages within the code, I would like to setup highlighting for all of that code. Sphinx briefly mentions a few of the languages it supports (<a href="http://sphinx.pocoo.org/markup/code.html" rel="noreferrer">on this page</a>), and then mentions that it uses <a href="http://pygments.org/" rel="noreferrer">Pygments</a> for lexical analysis and highlighting. Sifting through the documentation for both Sphinx and Pygments yielded me no clue on how to do something like highlight objective-c code.</p>
  
  <p>Pygments does mention the list of languages it supports, <a href="http://pygments.org/languages/" rel="noreferrer">here</a>, however that doesn't tell me the exact syntax that I must use within Sphinx (.rst files) to tell the code block to highlight for a specific language. For example, to highlight c++ code you simply use this before your code block:</p>
  
  <p><code>.. highlight:: c++</code></p>
  
  <p>However after trying these I cannot seem to highlight Objective-C code:</p>
  
  <pre><code>.. highlight:: Objective-C
  .. highlight:: objective-c
  .. highlight:: Obj-C
  .. highlight:: obj-c
  </code></pre>
  
  <p>Can anyone supply me with the list of languages (as you would refer to them within documentation)?</p>
