Standardizing a link using a global variable in Sphinx documentation - python-sphinx

I'm using Sphinx to document a project for work. I want to use the same link that points to a download on multiple pages throughout my documentation.
For example:
home.rst:
Hi
==
I want you to download_ my project.
.. _download: blah.com/download
other_page.rst
Hello Again
===========
You can also download_ it here.
.. _download: blah.com/download
Is there some way to have one variable that each page points to so when the link needs updated only on variable needs to be updated?

The best option is to use a substitution, rst_epilog, and raw-html as described in this answer for mailto links.
In your conf.py:
rst_epilog = """
.. role:: raw-html(raw)
:format: html
.. |download| replace:: :raw-html:`download`
"""
In your *.rst:
Please |download| my file.
The extlink extension is close, but assumes that you will want to use an URL as the base for other links to the site.

Combining replace and include in reStructuredText / Sphinx [duplicate]

I want to use the .. include:: function inline, but I can only get it to actually include the file I want if I separate it with two new lines from the previous text.
Before anyone asks, the file I want to include is a protocol number, so no, it doesn't benefit from a new line, at all. I want to be able to change it easily so I can use it on multiple places of my documentation. I guess that an example would be "We currently use the protocol (proto.txt)." I'm new to Sphinx and rst, so maybe there is a very obvious solution I haven't found.
Inline includes are not possible with Sphinx.
However, you can define global aliases (substitutions) in the rst_epilog variable of your build configuration file.
For example, you can add the following lines to your conf.pyfile:
rst_epilog = """
.. |version| replace:: 4.1
.. |protocol| replace:: httpx
"""
Now, you can access the variables |version| and |protocol| from any .rst file within your project, for example like this:
Version |version| uses the |protocol| protocol.
becomes
Version 4.1 uses the httpx protocol.
If other parts of your software require protocol (or other variables) to be specified in a specific file or format, you can write a script to read it from there as a variable into the Sphinx configuration file.

reStructuredText sphinx link to another document's anchor [duplicate]

How to insert a cross-reference in a reST/Sphinx page to either a sub-header or anchor in another page in the same documentation set?
The expression "reST/Sphinx" makes the scope of the question unclear. Is it about reStructuredText in general and Sphinx, or only about reStructuredText as used in Sphinx (and not reStructuredText in general)? I'm going to cover both since people using RST are likely to run into both cases at some point:
Sphinx
Besides the domain-specific directives that can be used to link to various entities like classes (:class:) there's the general :ref: directive, documented here. They give this example:
.. _my-reference-label:
Section to cross-reference
--------------------------
This is the text of the section.
It refers to the section itself, see :ref:`my-reference-label`.
Although the general hyperlinking mechanism offered by RST does work in Sphinx, the documentation recommends against using it when using Sphinx:
Using ref is advised over standard reStructuredText links to sections (like Section title_) because it works across files, when section headings are changed, and for all builders that support cross-references.
RST, in General
The tools that convert RST files to HTML do not necessarily have a notion of collection. This is the case for instance if you rely on github to convert RST files to HTML or if you use a command line tool like rst2html. Unfortunately, the various methods to use to get the desired result vary depending on which tool you are using. For instance, if you use rst2html and you want file A.rst to link to a section named "Section" in file other.rst and you want the final HTML to work in a browser, then A.rst would contain:
`This <other.html#section>`__ is a reference to a section in another
file, which works with ``rst2html``. Unfortunately, it does not work
when the HTML is generated through github.
You have to link to the final HTML file and you have to know what the id given to the section will be. If you want to do the same for a file served through github:
`This <other.rst#section>`__ is a reference to a section in another
file, which works on github. Unfortunately, it does not work when you
use ``rst2html``.
Here too you need to know the id given to the section. However, you link to the RST file because it is only upon accessing the RST file that the HTML is created. (At the time of writing this answer, accessing the HTML directly is not allowed.)
A complete example is available here.

The autosection extension lets you do this easily.
=============
Some Document
=============
Internal Headline
=================
then, later...
===============
Some Other Doc
===============
A link- :ref:`Internal Headline`
This extension is built-in, so all you need is to edit conf.py
extensions = [
.
. other
. extensions
. already
. listed
.
'sphinx.ext.autosectionlabel',
]
The only thing you have to be careful of is that now you can't duplicate internal headlines across the doc collection. (Worth it.)
Example:
Hey, read the :ref:`Installation:Homebrew` section.
where Homebrew is a section inside a different document named Installation.rst.
This uses the autosection feature, so will need to edit config.py with the following:
extensions = [
'sphinx.ext.autosectionlabel'
]
autosectionlabel_prefix_document = True
In Sphinx 3.0.3 the only solution that worked for me is :any: (see https://www.sphinx-doc.org/en/1.5/markup/inline.html#cross-referencing-anything).
Suppose, one document has such a section:
.. _my-section:
My Section
----------
Lorem ipsum blablabla
Then another document can have the following fragment to create a link:
See :any:`my-section` for the details
I was struggling to make this work and i found out that the actual notation is :ref:'{dir-path}/Installation:Homebrew' where {dir-path} is the relative path to Installation.rst from where config.py exists
Adding description of behavior that was confusing to me.
Section titles must be referenced with the file name (overview here) in front of it:
overview.rst:
************
API Overview
************
index.rst:
:ref:`overview:API Overview`
However, when referencing links, the file name (constants here) must not be there:
constants.rst:
.. _section-constants:
*******************
Enums and Constants
*******************
api.rst:
:ref:`section-constants`
Also, for this to work, one must enable extension 'autosectionlabel':
conf.py:
extensions = [
...
"sphinx.ext.autosectionlabel"
]
