## RST Code Blocks¶

Code blocks let you display literal text with or with or without syntax highlighting.

There are are several ways to show code examples or preformatted text.

• The :: directive is a generic code of preformatted text. Sphinx tries to guess at the language for syntax highlighted.

• The .. code-block:: language directive adds syntax highlighting and args.

• RST supports many languages! Here is the list:

• Code blocks can contain additional parameters, such as:

• :linenos:

• :lineno-start:

• :emphasize-lines:

• :caption:

• :dedent:

Here are some examples:

Generic block and syntax highlighting
::

This text is in a code block. Sphinx will use generic
text highlighting.

Plain text block
.. code-block:: text
:caption: Plain text block

<p>This text will have no styling. However, you can add
parameters to the block.</p>

Basic code block
.. code-block:: HTML

<span class="bold>sample HTML</span>

Code block with syntax highlighting and line numbers
 1 2 3 4 5 6 7 8 .. code-block:: bash :caption: Code block with syntax highlighting and line numbers :linenos: :emphasize-lines: 9,10,34,39,46 # This code block uses bash syntax highlighting # Also, a code-block has args for line numbers, # highlighting lines, and captions! 

1. Add important and note boxes

2. Add a bash code block for the Sphinx configuration options.

• Add line numbers and highlighting on lines 9,10,34,39,46.

Important: Create and then change to the directory of your Sphinx
code and RST content. The default installation directory is ./,
which is the current directory.

#. Create a project folder, then navigate to that folder

* For example: mkdir -p /opt/sphinx && cd /opt/sphinx

#. Execute command sphinx-quickstart
#. Follow the prompts (from version 1.x)

We've highlighted the lines that we entered a value *other than*
default. Add the extensions that you find useful.

Output of ‘sphinx-quickstart’
  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 > Separate source and build directories (y/n) [n]: Inside the root directory, two more directories will be created; "_templates" for custom HTML templates and "_static" for custom stylesheets and other static files. You can enter another prefix (such as ".") to replace the underscore. > Name prefix for templates and static dir [_]: The project name will occur in several places in the built documentation. > Project name: Conference Demo > Author name(s): BilimEdtech > Project release []: If the documents are to be written in a language other than English, you can select a language here by its language code. Sphinx will then translate text that it generates into that language. For a list of supported codes, see http://sphinx-doc.org/config.html#confval-language. > Project language [en]: The file name suffix for source files. Commonly, this is either ".txt" or ".rst". Only files with this suffix are considered documents. > Source file suffix [.rst]: One document is special in that it is considered the top node of the "contents tree", that is, it is the root of the hierarchical structure of the documents. Normally, this is "index", but if your "index" document is a custom template, you can also set this to another filename. > Name of your master document (without suffix) [index]: Indicate which of the following Sphinx extensions should be enabled: > autodoc: automatically insert docstrings from modules (y/n) [n]: > doctest: automatically test code snippets in doctest blocks (y/n) [n]: > intersphinx: link between Sphinx documentation of different projects (y/n) [n]: > todo: write "todo" entries that can be shown or hidden on build (y/n) [n]: y > coverage: checks for documentation coverage (y/n) [n]: > imgmath: include math, rendered as PNG or SVG images (y/n) [n]: > mathjax: include math, rendered in the browser by MathJax (y/n) [n]: > ifconfig: conditional inclusion of content based on config values (y/n) [n]: > viewcode: include links to the source code of documented Python objects (y/n) [n]: y > githubpages: create .nojekyll file to publish the document on GitHub pages (y/n) [n]: A Makefile and a Windows command file can be generated for you so that you only have to run e.g. make html instead of invoking sphinx-build directly. > Create Makefile? (y/n) [y]: > Create Windows command file? (y/n) [y]: n 
Note:

* The configurations for your Sphinx project are in file conf.py.
* Delete file conf.py to run quickstart again.
