Uhhh... This is extremely invasive IMO.

@pradyunsg I thought so. But atm I'm just doing what I was asked to do. It's easier to reason about stuff when there's a preview :)

I've colored it a bit. I'll let @nlhkabu / @jdittrich / @georgiamoon decide how to deal with the invasiveness.

FWIW it's a good start and can be tweaked.

I'll let @nlhkabu / @jdittrich / @georgiamoon decide how to deal with the invasiveness.

Imho it is too invasive on such a short page, but totally OK on a longer page. We could hide one in case of short pages (don't know how hard this is). We could also make the box less big in general:

The rendered list seems to be over-indented, probably because triple-quotes preserve whitespace. I can't view the reST output (after this extension is applied) due to the theme (it's just not trivially possible), but I think generally it'd be safer to declare all these literals as module level constants to avoid accidentally messing up indentation.

I hear you but because it's also augmented with another line with context-specific var, I'm not sure if moving it on the module level is a good idea. After all, we need to keep some sort of common indentation level here and 3 lines below.

I guess I'll just experiment with dedenting both.

I'd say: check if it's creating a blockquote in the final HTML. If it is, then you know that things are indented too far.

It is, and I was also concern about other texts provided as indented triple quoted literals, e.g. Did this article help? (relative to .. important). Sphinx is pretty relaxed and still renders the content even if it doesn't align with important, but I think it'd be easier to notice whitespace issues if the reST is provided as something close to unindented literals, which we can then str.format on.

I agree with @pradyunsg - this is too intrusive. Top or bottom is fine, but I'm not keen on both.

(Also, I think having the banner on the changelog page is probably a bit much, although I understand that it's an all-or-nothing thing because of the way it's implemented).

It's not an all-or-nothing proposition since we have the document name in the code that's adding the $thing. We can have conditionals to "opt out" for certain pages, if we want.

Exactly, we can change this once there's a general consensus on what exactly is needed.

We could hide one in case of short pages (don't know how hard this is).

The easiest way of doing this is to maintain a list of exclusions I think.

We could also make the box less big in general

Feel free to send a CSS patch with a specific suggestion. "less big" is too broad and is not very well actionable...

@jdittrich oh, I just looked at the picture again. Are you suggesting to drop the list?

Yes, that would be one way to make it smaller (which could be particularly important for the top box)

webknjaz commented Sep 7, 2020

Alright, so just to clarify the action items now:

  1. drop the list from the top box, but not the bottom one
  2. dedent the list
  3. implement page exclusions (not sure if everybody agrees on this one)

Anything I'm missing?

So I think I've made it a bit better:

  1. Now the list is only present in the bottom box but not the top one (as requested by @jdittrich) -- see https://pip--8848.org.readthedocs.build/en/8848/development/
  2. It is possible to exclude documents and I've added the news document to the exclude list (:wave: @pfmoore) -- see https://pip--8848.org.readthedocs.build/en/8848/news/
  3. Adjusted the indentation (@McSinyx ✌️)
  4. The top box is hidden if the document RST source has over 50 LOC (@jdittrich 🎉) -- see https://pip--8848.org.readthedocs.build/en/8848/
  5. I've added a number of external toggles so that it's possible to adjust the following w/o the need to look into the monstrous extension implementation:
    • box (admonition) type
    • the "big doc" threshold
    • the target email
    • the excluded documents set
    • the questions list

   ### 20.3b1
   ```
   ===================

Deprecations and Removals
-------------------------

- ``pip freeze`` will stop filtering the ``pip``, ``setuptools``, ``distribute`` and ``wheel`` packages from ``pip freeze`` output in a future version.
  To keep the previous behavior, users should use the new ``--exclude`` option. (`4256 &lt;https://github.com/pypa/pip/issues/4256&gt;`_)
- Deprecate support for Python 3.5 (`8181 &lt;https://github.com/pypa/pip/issues/8181&gt;`_)
- Document that certain removals can be fast tracked. (`8417 &lt;https://github.com/pypa/pip/issues/8417&gt;`_)
- Document that Python versions are generally supported until PyPI usage falls below 5%. (`8927 &lt;https://github.com/pypa/pip/issues/8927&gt;`_)
- Deprecate ``--find-links`` option in ``pip freeze`` (`9069 &lt;https://github.com/pypa/pip/issues/9069&gt;`_)

Features
--------

- Add ``--exclude`` option to ``pip freeze`` and ``pip list`` commands to explicitly exclude packages from the output. (`4256 &lt;https://github.com/pypa/pip/issues/4256&gt;`_)
- Allow multiple values for --abi and --platform. (`6121 &lt;https://github.com/pypa/pip/issues/6121&gt;`_)
- Add option ``--format`` to subcommand ``list`` of ``pip  cache``, with ``abspath`` choice to output the full path of a wheel file. (`8355 &lt;https://github.com/pypa/pip/issues/8355&gt;`_)
- Improve error message friendliness when an environment has packages with
  corrupted metadata. (`8676 &lt;https://github.com/pypa/pip/issues/8676&gt;`_)
- Make the ``setup.py install`` deprecation warning less noisy. We warn only
  when ``setup.py install`` succeeded and ``setup.py bdist_wheel`` failed, as
  situations where both fails are most probably irrelevant to this deprecation. (`8752 &lt;https://github.com/pypa/pip/issues/8752&gt;`_)
- Check the download directory for existing wheels to possibly avoid
  fetching metadata when the ``fast-deps`` feature is used with
  ``pip wheel`` and ``pip download``. (`8804 &lt;https://github.com/pypa/pip/issues/8804&gt;`_)
- When installing a git URL that refers to a commit that is not available locally
  after git clone, attempt to fetch it from the remote. (`8815 &lt;https://github.com/pypa/pip/issues/8815&gt;`_)
- Include http subdirectory in ``pip cache info`` and ``pip cache purge`` commands. (`8892 &lt;https://github.com/pypa/pip/issues/8892&gt;`_)
- Cache package listings on index packages so they are guarenteed to stay stable
  during a pip command session. This also improves performance when a index page
  is accessed multiple times during the command session. (`8905 &lt;https://github.com/pypa/pip/issues/8905&gt;`_)
- New resolver: Tweak resolution logic to improve user experience when
  user-supplied requirements conflict. (`8924 &lt;https://github.com/pypa/pip/issues/8924&gt;`_)
- Support Python 3.9. (`8971 &lt;https://github.com/pypa/pip/issues/8971&gt;`_)
- Log an informational message when backtracking takes multiple rounds on a specific package. (`8975 &lt;https://github.com/pypa/pip/issues/8975&gt;`_)
- Switch to the new dependency resolver by default. (`9019 &lt;https://github.com/pypa/pip/issues/9019&gt;`_)
- Remove the ``--build-dir`` option, as per the deprecation. (`9049 &lt;https://github.com/pypa/pip/issues/9049&gt;`_)

Bug Fixes
---------

- Propagate ``--extra-index-url`` from requirements file properly to session auth,
  so that keyring auth will work as expected. (`8103 &lt;https://github.com/pypa/pip/issues/8103&gt;`_)
- Allow specifying verbosity and quiet level via configuration files
  and environment variables. Previously these options were treated as
  boolean values when read from there while through CLI the level can be
  specified. (`8578 &lt;https://github.com/pypa/pip/issues/8578&gt;`_)
- Only converts Windows path to unicode on Python 2 to avoid regressions when a
  POSIX environment does not configure the file system encoding correctly. (`8658 &lt;https://github.com/pypa/pip/issues/8658&gt;`_)
- List downloaded distributions before exiting ``pip download``
  when using the new resolver to make the behavior the same as
  that on the legacy resolver. (`8696 &lt;https://github.com/pypa/pip/issues/8696&gt;`_)
- New resolver: Pick up hash declarations in constraints files and use them to
  filter available distributions. (`8792 &lt;https://github.com/pypa/pip/issues/8792&gt;`_)
- Avoid polluting the destination directory by resolution artifacts
  when the new resolver is used for ``pip download`` or ``pip wheel``. (`8827 &lt;https://github.com/pypa/pip/issues/8827&gt;`_)
- New resolver: If a package appears multiple times in user specification with
  different ``--hash`` options, only hashes that present in all specifications
  should be allowed. (`8839 &lt;https://github.com/pypa/pip/issues/8839&gt;`_)
- Tweak the output during dependency resolution in the new resolver. (`8861 &lt;https://github.com/pypa/pip/issues/8861&gt;`_)
- Correctly search for installed distributions in new resolver logic in order
  to not miss packages (virtualenv packages from system-wide-packages for example) (`8963 &lt;https://github.com/pypa/pip/issues/8963&gt;`_)
- Do not fail in pip freeze when encountering a ``direct_url.json`` metadata file
  with editable=True. Render it as a non-editable ``file://`` URL until modern
  editable installs are standardized and supported. (`8996 &lt;https://github.com/pypa/pip/issues/8996&gt;`_)

Vendored Libraries
------------------

- Fix devendoring instructions to explicitly state that ``vendor.txt`` should not be removed.
  It is mandatory for ``pip debug`` command.

Improved Documentation
----------------------

- Add documentation for &#39;.netrc&#39; support. (`7231 &lt;https://github.com/pypa/pip/issues/7231&gt;`_)
- Add OS tabs for OS-specific commands. (`7311 &lt;https://github.com/pypa/pip/issues/7311&gt;`_)
- Add note and example on keyring support for index basic-auth (`8636 &lt;https://github.com/pypa/pip/issues/8636&gt;`_)
- Added initial UX feedback widgets to docs. (`8783 &lt;https://github.com/pypa/pip/issues/8783&gt;`_, `8848 &lt;https://github.com/pypa/pip/issues/8848&gt;`_)
- Add ux documentation (`8807 &lt;https://github.com/pypa/pip/issues/8807&gt;`_)
- Update user docs to reflect new resolver as default in 20.3. (`9044 &lt;https://github.com/pypa/pip/issues/9044&gt;`_)
- Improve migration guide to reflect changes in new resolver behavior. (`9056 &lt;https://github.com/pypa/pip/issues/9056&gt;`_)

   ### 20.3b1
   ```
   ===================

Deprecations and Removals
-------------------------

- ``pip freeze`` will stop filtering the ``pip``, ``setuptools``, ``distribute`` and ``wheel`` packages from ``pip freeze`` output in a future version.
  To keep the previous behavior, users should use the new ``--exclude`` option. (`4256 &lt;https://github.com/pypa/pip/issues/4256&gt;`_)
- Deprecate support for Python 3.5 (`8181 &lt;https://github.com/pypa/pip/issues/8181&gt;`_)
- Document that certain removals can be fast tracked. (`8417 &lt;https://github.com/pypa/pip/issues/8417&gt;`_)
- Document that Python versions are generally supported until PyPI usage falls below 5%. (`8927 &lt;https://github.com/pypa/pip/issues/8927&gt;`_)
- Deprecate ``--find-links`` option in ``pip freeze`` (`9069 &lt;https://github.com/pypa/pip/issues/9069&gt;`_)

Features
--------

- Add ``--exclude`` option to ``pip freeze`` and ``pip list`` commands to explicitly exclude packages from the output. (`4256 &lt;https://github.com/pypa/pip/issues/4256&gt;`_)
- Allow multiple values for --abi and --platform. (`6121 &lt;https://github.com/pypa/pip/issues/6121&gt;`_)
- Add option ``--format`` to subcommand ``list`` of ``pip  cache``, with ``abspath`` choice to output the full path of a wheel file. (`8355 &lt;https://github.com/pypa/pip/issues/8355&gt;`_)
- Improve error message friendliness when an environment has packages with
  corrupted metadata. (`8676 &lt;https://github.com/pypa/pip/issues/8676&gt;`_)
- Make the ``setup.py install`` deprecation warning less noisy. We warn only
  when ``setup.py install`` succeeded and ``setup.py bdist_wheel`` failed, as
  situations where both fails are most probably irrelevant to this deprecation. (`8752 &lt;https://github.com/pypa/pip/issues/8752&gt;`_)
- Check the download directory for existing wheels to possibly avoid
  fetching metadata when the ``fast-deps`` feature is used with
  ``pip wheel`` and ``pip download``. (`8804 &lt;https://github.com/pypa/pip/issues/8804&gt;`_)
- When installing a git URL that refers to a commit that is not available locally
  after git clone, attempt to fetch it from the remote. (`8815 &lt;https://github.com/pypa/pip/issues/8815&gt;`_)
- Include http subdirectory in ``pip cache info`` and ``pip cache purge`` commands. (`8892 &lt;https://github.com/pypa/pip/issues/8892&gt;`_)
- Cache package listings on index packages so they are guarenteed to stay stable
  during a pip command session. This also improves performance when a index page
  is accessed multiple times during the command session. (`8905 &lt;https://github.com/pypa/pip/issues/8905&gt;`_)
- New resolver: Tweak resolution logic to improve user experience when
  user-supplied requirements conflict. (`8924 &lt;https://github.com/pypa/pip/issues/8924&gt;`_)
- Support Python 3.9. (`8971 &lt;https://github.com/pypa/pip/issues/8971&gt;`_)
- Log an informational message when backtracking takes multiple rounds on a specific package. (`8975 &lt;https://github.com/pypa/pip/issues/8975&gt;`_)
- Switch to the new dependency resolver by default. (`9019 &lt;https://github.com/pypa/pip/issues/9019&gt;`_)
- Remove the ``--build-dir`` option, as per the deprecation. (`9049 &lt;https://github.com/pypa/pip/issues/9049&gt;`_)

Bug Fixes
---------

- Propagate ``--extra-index-url`` from requirements file properly to session auth,
  so that keyring auth will work as expected. (`8103 &lt;https://github.com/pypa/pip/issues/8103&gt;`_)
- Allow specifying verbosity and quiet level via configuration files
  and environment variables. Previously these options were treated as
  boolean values when read from there while through CLI the level can be
  specified. (`8578 &lt;https://github.com/pypa/pip/issues/8578&gt;`_)
- Only converts Windows path to unicode on Python 2 to avoid regressions when a
  POSIX environment does not configure the file system encoding correctly. (`8658 &lt;https://github.com/pypa/pip/issues/8658&gt;`_)
- List downloaded distributions before exiting ``pip download``
  when using the new resolver to make the behavior the same as
  that on the legacy resolver. (`8696 &lt;https://github.com/pypa/pip/issues/8696&gt;`_)
- New resolver: Pick up hash declarations in constraints files and use them to
  filter available distributions. (`8792 &lt;https://github.com/pypa/pip/issues/8792&gt;`_)
- Avoid polluting the destination directory by resolution artifacts
  when the new resolver is used for ``pip download`` or ``pip wheel``. (`8827 &lt;https://github.com/pypa/pip/issues/8827&gt;`_)
- New resolver: If a package appears multiple times in user specification with
  different ``--hash`` options, only hashes that present in all specifications
  should be allowed. (`8839 &lt;https://github.com/pypa/pip/issues/8839&gt;`_)
- Tweak the output during dependency resolution in the new resolver. (`8861 &lt;https://github.com/pypa/pip/issues/8861&gt;`_)
- Correctly search for installed distributions in new resolver logic in order
  to not miss packages (virtualenv packages from system-wide-packages for example) (`8963 &lt;https://github.com/pypa/pip/issues/8963&gt;`_)
- Do not fail in pip freeze when encountering a ``direct_url.json`` metadata file
  with editable=True. Render it as a non-editable ``file://`` URL until modern
  editable installs are standardized and supported. (`8996 &lt;https://github.com/pypa/pip/issues/8996&gt;`_)

Vendored Libraries
------------------

- Fix devendoring instructions to explicitly state that ``vendor.txt`` should not be removed.
  It is mandatory for ``pip debug`` command.

Improved Documentation
----------------------

- Add documentation for &#39;.netrc&#39; support. (`7231 &lt;https://github.com/pypa/pip/issues/7231&gt;`_)
- Add OS tabs for OS-specific commands. (`7311 &lt;https://github.com/pypa/pip/issues/7311&gt;`_)
- Add note and example on keyring support for index basic-auth (`8636 &lt;https://github.com/pypa/pip/issues/8636&gt;`_)
- Added initial UX feedback widgets to docs. (`8783 &lt;https://github.com/pypa/pip/issues/8783&gt;`_, `8848 &lt;https://github.com/pypa/pip/issues/8848&gt;`_)
- Add ux documentation (`8807 &lt;https://github.com/pypa/pip/issues/8807&gt;`_)
- Update user docs to reflect new resolver as default in 20.3. (`9044 &lt;https://github.com/pypa/pip/issues/9044&gt;`_)
- Improve migration guide to reflect changes in new resolver behavior. (`9056 &lt;https://github.com/pypa/pip/issues/9056&gt;`_)

   ```
   ===================

Deprecations and Removals
-------------------------

- ``pip freeze`` will stop filtering the ``pip``, ``setuptools``, ``distribute`` and ``wheel`` packages from ``pip freeze`` output in a future version.
  To keep the previous behavior, users should use the new ``--exclude`` option. (`4256 &lt;https://github.com/pypa/pip/issues/4256&gt;`_)
- Deprecate support for Python 3.5 (`8181 &lt;https://github.com/pypa/pip/issues/8181&gt;`_)
- Document that certain removals can be fast tracked. (`8417 &lt;https://github.com/pypa/pip/issues/8417&gt;`_)
- Document that Python versions are generally supported until PyPI usage falls below 5%. (`8927 &lt;https://github.com/pypa/pip/issues/8927&gt;`_)
- Deprecate ``--find-links`` option in ``pip freeze`` (`9069 &lt;https://github.com/pypa/pip/issues/9069&gt;`_)

Features
--------

- Add ``--exclude`` option to ``pip freeze`` and ``pip list`` commands to explicitly exclude packages from the output. (`4256 &lt;https://github.com/pypa/pip/issues/4256&gt;`_)
- Allow multiple values for --abi and --platform. (`6121 &lt;https://github.com/pypa/pip/issues/6121&gt;`_)
- Add option ``--format`` to subcommand ``list`` of ``pip  cache``, with ``abspath`` choice to output the full path of a wheel file. (`8355 &lt;https://github.com/pypa/pip/issues/8355&gt;`_)
- Improve error message friendliness when an environment has packages with
  corrupted metadata. (`8676 &lt;https://github.com/pypa/pip/issues/8676&gt;`_)
- Make the ``setup.py install`` deprecation warning less noisy. We warn only
  when ``setup.py install`` succeeded and ``setup.py bdist_wheel`` failed, as
  situations where both fails are most probably irrelevant to this deprecation. (`8752 &lt;https://github.com/pypa/pip/issues/8752&gt;`_)
- Check the download directory for existing wheels to possibly avoid
  fetching metadata when the ``fast-deps`` feature is used with
  ``pip wheel`` and ``pip download``. (`8804 &lt;https://github.com/pypa/pip/issues/8804&gt;`_)
- When installing a git URL that refers to a commit that is not available locally
  after git clone, attempt to fetch it from the remote. (`8815 &lt;https://github.com/pypa/pip/issues/8815&gt;`_)
- Include http subdirectory in ``pip cache info`` and ``pip cache purge`` commands. (`8892 &lt;https://github.com/pypa/pip/issues/8892&gt;`_)
- Cache package listings on index packages so they are guarenteed to stay stable
  during a pip command session. This also improves performance when a index page
  is accessed multiple times during the command session. (`8905 &lt;https://github.com/pypa/pip/issues/8905&gt;`_)
- New resolver: Tweak resolution logic to improve user experience when
  user-supplied requirements conflict. (`8924 &lt;https://github.com/pypa/pip/issues/8924&gt;`_)
- Support Python 3.9. (`8971 &lt;https://github.com/pypa/pip/issues/8971&gt;`_)
- Log an informational message when backtracking takes multiple rounds on a specific package. (`8975 &lt;https://github.com/pypa/pip/issues/8975&gt;`_)
- Switch to the new dependency resolver by default. (`9019 &lt;https://github.com/pypa/pip/issues/9019&gt;`_)
- Remove the ``--build-dir`` option, as per the deprecation. (`9049 &lt;https://github.com/pypa/pip/issues/9049&gt;`_)

Bug Fixes
---------

- Propagate ``--extra-index-url`` from requirements file properly to session auth,
  so that keyring auth will work as expected. (`8103 &lt;https://github.com/pypa/pip/issues/8103&gt;`_)
- Allow specifying verbosity and quiet level via configuration files
  and environment variables. Previously these options were treated as
  boolean values when read from there while through CLI the level can be
  specified. (`8578 &lt;https://github.com/pypa/pip/issues/8578&gt;`_)
- Only converts Windows path to unicode on Python 2 to avoid regressions when a
  POSIX environment does not configure the file system encoding correctly. (`8658 &lt;https://github.com/pypa/pip/issues/8658&gt;`_)
- List downloaded distributions before exiting ``pip download``
  when using the new resolver to make the behavior the same as
  that on the legacy resolver. (`8696 &lt;https://github.com/pypa/pip/issues/8696&gt;`_)
- New resolver: Pick up hash declarations in constraints files and use them to
  filter available distributions. (`8792 &lt;https://github.com/pypa/pip/issues/8792&gt;`_)
- Avoid polluting the destination directory by resolution artifacts
  when the new resolver is used for ``pip download`` or ``pip wheel``. (`8827 &lt;https://github.com/pypa/pip/issues/8827&gt;`_)
- New resolver: If a package appears multiple times in user specification with
  different ``--hash`` options, only hashes that present in all specifications
  should be allowed. (`8839 &lt;https://github.com/pypa/pip/issues/8839&gt;`_)
- Tweak the output during dependency resolution in the new resolver. (`8861 &lt;https://github.com/pypa/pip/issues/8861&gt;`_)
- Correctly search for installed distributions in new resolver logic in order
  to not miss packages (virtualenv packages from system-wide-packages for example) (`8963 &lt;https://github.com/pypa/pip/issues/8963&gt;`_)
- Do not fail in pip freeze when encountering a ``direct_url.json`` metadata file
  with editable=True. Render it as a non-editable ``file://`` URL until modern
  editable installs are standardized and supported. (`8996 &lt;https://github.com/pypa/pip/issues/8996&gt;`_)

Vendored Libraries
------------------

- Fix devendoring instructions to explicitly state that ``vendor.txt`` should not be removed.
  It is mandatory for ``pip debug`` command.

Improved Documentation
----------------------

- Add documentation for &#39;.netrc&#39; support. (`7231 &lt;https://github.com/pypa/pip/issues/7231&gt;`_)
- Add OS tabs for OS-specific commands. (`7311 &lt;https://github.com/pypa/pip/issues/7311&gt;`_)
- Add note and example on keyring support for index basic-auth (`8636 &lt;https://github.com/pypa/pip/issues/8636&gt;`_)
- Added initial UX feedback widgets to docs. (`8783 &lt;https://github.com/pypa/pip/issues/8783&gt;`_, `8848 &lt;https://github.com/pypa/pip/issues/8848&gt;`_)
- Add ux documentation (`8807 &lt;https://github.com/pypa/pip/issues/8807&gt;`_)
- Update user docs to reflect new resolver as default in 20.3. (`9044 &lt;https://github.com/pypa/pip/issues/9044&gt;`_)
- Improve migration guide to reflect changes in new resolver behavior. (`9056 &lt;https://github.com/pypa/pip/issues/9056&gt;`_)
