Now, I want to split this file into namespace, class, and function files. For instance, in our case, there should be 1 file for the namespace, 1 file for the class, and 3 files for class functions.
One way to do this is to use .. include:: directive. However, this raises the following unresolvable warnings:
src/class_shapes__Square.rst:5: WARNING: duplicate label class_shapes__square, other instance in C:\Users\pc\Desktop\src\class_shapes__Square.rst
src/class_shapes__Square.rst:27: WARNING: duplicate label function__double_shapes__square__area, other instance in C:\Users\pc\Desktop\src\class_shapes__Square.rst
src/class_shapes__Square.rst:38: WARNING: duplicate label function__double_shapes__square__width, other instance in C:\Users\pc\Desktop\src\class_shapes__Square.rst
src/class_shapes__Square.rst:49: WARNING: duplicate label function__shapes__square__square, other instance in C:\Users\pc\Desktop\src\class_shapes__Square.rst
In the case of large projects, a large number of warnings cause failure to output HTML documentation.
I tried the following solutions:
Get rid of "duplicate label" warning in Sphinx
Sphinx's .. include:: directive and "duplicate label" warnings
I failed to become successful by following these solutions.
So, how can I do this?
Move the label and its section heading out of the included file and up into the file that does the inclusion.
For example:
namespace_shapes.rst
.. _function__double_shapes__Square__width:
double width() const
====================
.. include:: double-width.rst
double-width.rst
double shapes::Square::width () const
-------------------------------------
Returns width of this square.
You would need to change the label for each instance to make it unique. It's not a great solution, but at least the duplicate label warning will not occur.
Alternatively remove labels so that they do not generate warnings. Of course that means you would lose an arbitrary reference, so not the best option.
Maybe the problem appears, because the included file extension are also called .rst. Try with .rest or any other file extension...
Found this solution here: https://stackoverflow.com/a/69474038/20176022
TL,DR: From a Sphinx extension, how do I tell sphinx-build to treat an additional file as a dependency? In my immediate use case, this is the extension's source code, but the question could equally apply to some auxiliary file used by the extension.
I'm generating documentation with Sphinx using a custom extension. I'm using sphinx-build to build the documentation. For example, I use this command to generate the HTML (this is the command in the makefile generated by sphinx-quickstart):
sphinx-build -b html -d _build/doctrees . _build/html
Since my custom extension is maintained together with the source of the documentation, I want sphinx-build to treat it as a dependency of the generated HTML (and LaTeX, etc.). So whenever I change my extension's source code, I want sphinx-build to regenerate the output.
How do I tell sphinx-build to treat an additional file as a dependency? That is not mentioned in the toctree, since it isn't part of the source. Logically, this should be something I do from my extension's setup function.
Sample extension (my_extension.py):
from docutils import nodes
from docutils.parsers.rst import Directive
class Foo(Directive):
def run(self):
node = nodes.paragraph(text='Hello world\n')
return [node]
def setup(app):
app.add_directive('foo', Foo)
Sample source (index.rst):
.. toctree::
:maxdepth: 2
.. foo::
Sample conf.py (basically the output of sphinx-quickstart plus my extension):
import sys
import os
sys.path.insert(0, os.path.abspath('.'))
extensions = ['my_extension']
templates_path = ['_templates']
source_suffix = '.rst'
master_doc = 'index'
project = 'Hello directive'
copyright = '2019, Gilles'
author = 'Gilles'
version = '1'
release = '1'
language = None
exclude_patterns = ['_build']
pygments_style = 'sphinx'
todo_include_todos = False
html_theme = 'alabaster'
html_static_path = ['_static']
htmlhelp_basename = 'Hellodirectivedoc'
latex_elements = {
}
latex_documents = [
(master_doc, 'Hellodirective.tex', 'Hello directive Documentation',
'Gilles', 'manual'),
]
man_pages = [
(master_doc, 'hellodirective', 'Hello directive Documentation',
[author], 1)
]
texinfo_documents = [
(master_doc, 'Hellodirective', 'Hello directive Documentation',
author, 'Hellodirective', 'One line description of project.',
'Miscellaneous'),
]
Validation of a solution:
Run make html (or sphinx-build as above).
Modify my_extension.py to replace Hello world by Hello again.
Run make html again.
The generated HTML (_build/html/index.html) must now contain Hello again instead of Hello world.
It looks like the note_dependency method in the build environment API should do what I want. But when should I call it? I tried various events but none seemed to hit the environment object in the right state. What did work was to call it from a directive.
import os
from docutils import nodes
from docutils.parsers.rst import Directive
import sphinx.application
class Foo(Directive):
def run(self):
self.state.document.settings.env.note_dependency(__file__)
node = nodes.paragraph(text='Hello done\n')
return [node]
def setup(app):
app.add_directive('foo', Foo)
If a document contains at least one foo directive, it'll get marked as stale when the extension that introduces this directive changes. This makes sense, although it could get tedious if an extension adds many directives or makes different changes. I don't know if there's a better way.
Inspired by Luc Van Oostenryck's autodoc-C.
As far as I know app.env.note_dependency can be called within the doctree-read to add any file as a dependency to the document currently being read.
So in your use case, I assume this would work:
from typing import Any, Dict
from sphinx.application import Sphinx
import docutils.nodes as nodes
def doctree-read(app: Sphinx, doctree: nodes.document):
app.env.note_dependency(file)
def setup(app: Sphinx):
app.connect("doctree-read", doctree-read)
Suppose I have two files a.rst and b.rst in the same folder, and a.rst looks like this
.. _foo: http://stackoverflow.com
`foo`_ is a website
It seems using foo in b.rst is not allowed. Is there a way to define hyperlinks and use them in multiple files?
Followup
I used the extlinks extension as Steve Piercy suggested. Its implementation and docstring can be seen here on github.
In my case, I define wikipedia link in my conf.py
extlinks = {'wiki': ('https://en.wikipedia.org/wiki/%s', '')}
and in the .rst files, use them like
:wiki:`Einstein <Albert_Einstein>`
where Einstein will be displayed as a link to https://en.wikipedia.org/wiki/Albert_Einstein
There are at least four possible solutions.
1. repeat yourself
Put your complete reST in each file. You probably don't want that.
2. combined rst_epilog and substitution
This one is clever. Configure the rst_epilog value, in your conf.py along with a substition with the replace directive:
rst_epilog = """
.. |foo| replace:: foo
.. _foo: http://stackoverflow.com
"""
and reST:
|foo|_ is a website
yields:
<a class="reference external" href="http://stackoverflow.com">foo</a>
3. extlinks
For links to external websites where you want to have a base URL and append path segments or arguments, you can use extlinks in your conf.py:
extensions = [
...
'sphinx.ext.extlinks',
...
]
...
extlinks = {'so': ('https://stackoverflow.com/%s', None)}
Then in your reST:
:so:`questions/49016433`
Yields:
<a class="reference external"
href="https://stackoverflow.com/questions/49016433">
https://stackoverflow.com/questions/49016433
</a>
4. intersphinx
For external websites that are documentation generated by Sphinx, then you can use intersphinx, in your conf.py:
extensions = [
...
'sphinx.ext.intersphinx',
...
]
...
intersphinx_mapping = {
'python': ('https://docs.python.org/3', None),
}
Then in your reST:
:py:mod:`doctest`
Yields:
<a class="reference external"
href="https://docs.python.org/3/library/doctest.html#module-doctest"
title="(in Python v3.6)">
<code class="xref py py-mod docutils literal">
<span class="pre">doctest</span>
</code>
</a>
This might come a bit late but I have found a solution that works very neatly for me and it is not among the answers already given.
In my case, I create a file with all the links used in my project, save it as /include/links.rst, and looking something like:
.. _PEP8: https://www.python.org/dev/peps/pep-0008/
.. _numpydoc: https://numpydoc.readthedocs.io/en/latest/format.html
.. _googledoc: https://google.github.io/styleguide/pyguide.html
Then there are the files a.rst and b.rst looking like:
.. include:: /include/links.rst
File A.rst
##########
Click `here <PEP8_>`_ to see the PEP8 coding style
Alternatively, visit either:
- `Numpy Style <numpydoc_>`_
- `Google Style <googledoc_>`_
and
.. include:: /include/links.rst
File B.rst
##########
You can visit `Python's PEP8 Style Guide <PEP8_>`_
For docstrings, you can use either `Numpy's <numpydoc_>`_ or `Google's <googledoc_>`_
respectively.
The produced output for both cases is:
and
respectively.
Moreover, I would like to emphasize the fact of which I was actually really struggling to achieve, to use different names (displayed text) for the same link at different locations and which I have achieved with the double _, one inside the <..._> and another outside.
This is another solution: it is a bit hacky and a little bit different respect to the officially supported way to share external links.
First complete the Setup then:
in conf.py add the commonlinks entry in extensions
in conf.py configure the map of common links:
For example:
extensions = [
...,
'sphinx.ext.commonlinks'
]
commonlinks = {
'issues': 'https://github.com/sphinx-doc/sphinx/issues',
'github': 'https://github.com'
}
Then in .rst files you can do these:
The :github:`_url_` url is aliased to :github:`GitHub` and also to :github:`this`
Setup
All that is needed is to copy into sphinx/ext directory the file commonlinks.py:
# -*- coding: utf-8 -*-
"""
sphinx.ext.commonlinks
~~~~~~~~~~~~~~~~~~~~~~
Extension to save typing and prevent hard-coding of common URLs in the reST
files.
This adds a new config value called ``commonlinks`` that is created like this::
commonlinks = {'exmpl': 'http://example.com/mypage.html', ...}
Now you can use e.g. :exmpl:`foo` in your documents. This will create a
link to ``http://example.com/mypage.html``. The link caption depends on the
role content:
- If it is ``_url_``, the caption will be the full URL.
- If it is a string, the caption will be the role content.

To locate the sphinx installation directory one way is:

then:
% cp commonlinks.py /usr/local/lib/python3.5/dist-packages/sphinx/ext
Sphinx can define themes as well as a pygments style to use.
I couldn't however - find a good way for a Sphinx project to define a custom style (color scheme) for pygments to use.
From the docs:
To make the style usable for Pygments, you must
either register it as a plugin (see the plugin docs)
or drop it into the styles subpackage of your Pygments distribution one style class per style, where the file name is the style name and the class name is StylenameClass.
From what I can tell the first option is what I'm after since it should be possible to extend pygments dynamically. Although from checking the link I'm not sure how this would be done (no examples of how to use the plugin system).
The second example involves copying files into pygments which isn't practical especially since the path may not be writable by the user.
I did manage to hack in a style, although it's not a nice solution:
including for completeness
# Sphinx "conf.py"
# Master toctree document
master_doc = 'contents'
# BEGIN MONKEY-PATCH
from pygments.style import Style
from pygments.token import Text, Other, Comment, Whitespace
class MyFancyStyle(Style):
background_color = "#1e1e27"
default_style = ""
styles = {
Text: "#cfbfad",
Other: "#cfbfad",
Whitespace: "#434357",
Comment: "#cd8b00",
Comment.Preproc: "#409090",
Comment.PreprocFile: "bg:#404040 #ffcd8b",
Comment.Special: "#808bed",
# ... snip (just more colors, you get the idea) ...
}
def pygments_monkeypatch_style(mod_name, cls):
import sys
import pygments.styles
cls_name = cls.__name__
mod = type(__import__("os"))(mod_name)
setattr(mod, cls_name, cls)
setattr(pygments.styles, mod_name, mod)
sys.modules["pygments.styles." + mod_name] = mod
from pygments.styles import STYLE_MAP
STYLE_MAP[mod_name] = mod_name + "::" + cls_name
pygments_monkeypatch_style("my_fancy_style", MyFancyStyle)
pygments_style = "my_fancy_style"
# END MONKEY-PATCH
In your conf.py specify the Pygments style you want to use. From the Sphinx documentation:
pygments_style
The style name to use for Pygments highlighting of source code. If not set, either the theme’s default style or 'sphinx' is selected for HTML output.
Available names can be retrieved by:
>>> from pygments.styles import get_all_styles
>>> styles = list(get_all_styles())
An online preview of some Sphinx theme and Pygments style combinations is available.
If out-of-the-box Pygments styles are not to your liking, then you can create a custom Pygments style.
This is how I set it up:
Folder Structure:
docs
├── source
│ ├── conf.py <--
│ ├── _pygments
│ │ ├── style.py <--
│ ├── _static
│ ├── ...
conf.py
(at the very top)
import sys, os
sys.path.append(os.path.abspath("./_pygments"))
pygments_style = 'style.MonokaiStyle'
...
style.py
from pygments.style import Style
from pygments.token import Keyword, Name, Comment, String, Error, Text, \
Number, Operator, Generic, Whitespace, Punctuation, Other, Literal
class MonokaiStyle(Style):
"""
This style mimics the Monokai color scheme.
"""
background_color = "#272822"
highlight_color = "#49483e"
styles = {
# No corresponding class for the following:
Text: "#f8f8f2", # class: ''
Whitespace: "", # class: 'w'
Error: "#960050 bg:#1e0010", # class: 'err'
Other: "", # class 'x'
...
}
You can choose a predefined style here (as I did) and put the corresponding *.py file from the official pygment repo into the _pygment folder. Or you can define your own style, renaming the class to your liking (don't forget to adapt the import clause in conf.py to the new names)
EDIT: This is an even better resource for style lookup.
I had a similar need, though what I really wanted was to slightly change an existing style (called the base style below). I was able to extent the code in the question for my needs. I post it here for anyone else coming across this problem.
# Sphinx "conf.py"
# Syntax highlighting of code blocks
import pygments.styles, pygments.token
def monkeypatch_pygments(name, base_name='default', attrs={}):
import importlib, sys
base_module = importlib.import_module('.'.join(['pygments', 'styles', base_name]))
def name_to_class_name(name):
return name.capitalize() + 'Style'
base_class = getattr(base_module, name_to_class_name(base_name))
styles = getattr(base_class, 'styles', {}).copy()
styles.update(attrs.pop('styles', {}))
attrs['styles'] = styles
class_name = name_to_class_name(name)
Style = type(class_name, (base_class,), attrs)
module = type(base_module)(name)
setattr(module, class_name, Style)
setattr(pygments.styles, name, module)
pygments.styles.STYLE_MAP[name] = f'{name}::{class_name}'
sys.modules['.'.join(['pygments', 'styles', name])] = module
pygments_style = 'custom' # Arbitrary name of new style
monkeypatch_pygments(
pygments_style,
'friendly', # Name of base style to use
{
# Changes to base style
'background_color': '#f6f6f6',
'styles': {
pygments.token.Comment: 'italic #688F98',
pygments.token.Name.Variable: '#d27a0a',
},
},
)
In the above example, the friendly style is used as the base style. Its 'background_color' and a few items within the 'styles' dictionary are redefined. Note that items not specified in 'styles' will be taken from the base style. The base style itself is not changed.
The "proper" way to include a pygments style as a plugin is to make a new package and install it via setuptools.
Use the usual process to create a setup.cfg (https://setuptools.readthedocs.io/en/latest/userguide/declarative_config.html)
Add the following section to it:
[options.entry_points]
pygments.styles =
my_fancy_style = mypackage.mystyle:MyFancyStyle
Create your style as class MyFancyStyle in mypackage/mystyle.py
Install the package: pip install -e .
Profit! You can now refer use "my_fancy_style" anywhere a Pygments style is expected. Phew.
I adopt the solution of Glades and it works well, except in the case that the style-python package is installed (style-1.1.0 in my case).
It lead to the ERROR (sorry for the part of french in the ouput) :
Une exception a été levée :
File "/home/bp/.local/lib/python3.8/site-packages/style/styled_string_builder.py", line 44, in __getattr__
raise AttributeError('%r object has no attribute %r' % (self.__class__.__name__, attr))
AttributeError: '_StyledStringBuilder' object has no attribute 'MonokaiStyle'
Only solution I find is just to uninstall this package named style :
$ pip uninstall style

This has now been resolved in rst2pdf via PR 619.
You can install the version of rst2pdf that has this fix by doing this:
$ cd {some directory where you keep 3rd-party projects, e.g. ~/projects}
$ git clone https://github.com/rst2pdf/rst2pdf.git
$ cd rst2pdf
$ python setup.py install
If you are still getting this message in 2021, it likely means rst2pdf can't figure out where one or more of your links is pointed. For example, I had in-page nav links in my .rst code like this that were ok when building HTML but causing the error referred to by the OP during PDF generation:

The most reliable solution seems to be to remove these in-page links.
Alternatively, you could just convert these implicit links to raw html blocks like below, which could be a solution if you can get rst2pdf to render raw html using xhtml2pdf (this isn't working for me, but perhaps someone else can get it).
.. |top| raw:: html
Back to top ↑
|top|
Note that in this alternative solution, the in-page links probably will not work in most PDF viewers, so this is really only a solution to get .rst files to compile to both PDF and HTML (as the OP asked), rather than one that will allow identical behavior.
