builder
A class (inheriting from :class:`~sphinx.builders.Builder`) that takes
parsed documents and performs an action on them. Normally, builders
translate the documents to an output format, but it is also possible to
use the builder builders that e.g. check for broken links in the
documentation, or build coverage information.
See :ref:`builders` for an overview over Sphinx's built-in builders.
configuration directory
The directory containing :file:`conf.py`. By default, this is the same as
the :term:`source directory`, but can be set differently with the **-c**
command-line option.
directive
A reStructuredText markup element that allows marking a block of content
with special meaning. Directives are supplied not only by docutils, but
Sphinx and custom extensions can add their own. The basic directive
syntax looks like this:
.. sourcecode:: rst
.. directivename:: argument ...
:option: value
Content of the directive.
See :ref:`directives` for more information.
document name
Since reST source files can have different extensions (some people like
``.txt``, some like ``.rst`` -- the extension can be configured with
:confval:`source_suffix`) and different OSes have different path
separators, Sphinx abstracts them: :dfn:`document names` are always
relative to the :term:`source directory`, the extension is stripped, and
path separators are converted to slashes. All values, parameters and such
referring to "documents" expect such document names.
Examples for document names are ``index``, ``library/zipfile``, or
``reference/datamodel/types``. Note that there is no leading or trailing
slash.
domain
A domain is a collection of markup (reStructuredText :term:`directive`\ s
and :term:`role`\ s) to describe and link to :term:`object`\ s belonging
together, e.g. elements of a programming language. Directive and role
names in a domain have names like ``domain:name``, e.g. ``py:function``.
Having domains means that there are no naming problems when one set of
documentation wants to refer to e.g. C++ and Python classes. It also
means that extensions that support the documentation of whole new
languages are much easier to write. For more information about domains,
see the chapter :ref:`domains`.
environment
A structure where information about all documents under the root is saved,
and used for cross-referencing. The environment is pickled after the
parsing stage, so that successive runs only need to read and parse new and
changed documents.
master document
The document that contains the root :rst:dir:`toctree` directive.
object
The basic building block of Sphinx documentation. Every "object
directive" (e.g. :rst:dir:`function` or :rst:dir:`object`) creates such a
block; and most objects can be cross-referenced to.
role
A reStructuredText markup element that allows marking a piece of text.
Like directives, roles are extensible. The basic syntax looks like this:
``:rolename:`content```. See :ref:`inlinemarkup` for details.
source directory
The directory which, including its subdirectories, contains all source
files for one Sphinx project.
