The single backtick in ReST is the "default role". Currently, Sphinx's
default role is called "content". Sphinx suggests you can use the "Any"
role instead to turn any single-backtick enclosed item into a
cross-reference.
Before we do that, though, we'll need to turn all existing usages of the
"content" role to inline verbatim markup by using double backticks
instead.

I'm reworking this patch and dropping the DO-NOT-MERGE and fixing this
reference to read:
:ref:`docker-ref`
This works *without* my other sphinx patches, so it should now stand alone.
I've sent this as a standalone patch to qemu-trivial.
(I'll fix it in this branch too, but it's DO-NOT-MERGE here, so ...
whatever!)

After this I get:
qemu/docs/cpu-hotplug.rst:81: WARNING: 'any' reference target not found: query-cpus-fast
So I missed it during the review of the first patch ("docs: replace
single backtick (`) with double-backtick (``)").
- Cleber.

Not sure why I didn't encounter that. Maybe version troubles again?

What are you invoking to get this to fail?
I am typing "make sphinxdocs".
It doesn't look like this document is actually built as part of the
manual for me.

I did not say "sphinx beautiful", just "sphinx compatible". They will
not throw errors when parsed and interpreted as ReST.

If you're making it compatible, why not take the time to give
backticks to start_if and end_if?
Bonus points for setting the "meth" role, but not lost points for not
doing it, as I understand this is beyond what you're attempting at
this time.

I would argue that this is not a strict sphinx compatibility change,
but a fix to a broken docstring.

I remain unsold on using explicit roles for references in docstrings,
because I'd like to keep the amount of Sphinx-ese syntax down to a
minimum if I can. The double backticks are bad enough ...

Not entirely correct: the syntax of *args breaks document generation.

For whatever reason, when these are stored as functions instead of
strings, it confuses sphinx-autodoc into believing them to be
docstrings, and it chokes on the syntax.
Keeping them as dumb strings instead avoids the problem.

Quoting my review of the patch that added it: "This .format business is
perhaps a bit too clever. But let's move on."
doc.py is about to be replaced, obsoleting this patch. Regardless:

It seems perfectly fine, and I have no real explanation for why it
confuses autodoc.
I think autodoc is using regex that it maybe shouldn't be to identify
some constructs instead of the proper Python AST. I looked extremely
briefly but made the assessment it wasn't going to be quick.

Yes, understood -- until such time as it is actually deleted, I am
keeping it updated with the style I am trying to enforce just to make my
own life simpler.
It's no problem to just trash it when the time comes, but in this case I
wanted to explore what stopped us from using Sphinx autodoc earnestly --
and it just so happened that this was the sticking point.
Thanks for looking!

I actually think it's a more honest approach, and easier to read.

also changing the quote style?

Was just trying to differentiate it from docstrings to see if it helped.
It didn't, but it also didn't hurt, so I left it.
Luckily, this patch won't matter after Peter Maydell's series goes in,
so whatever!

This renders *very* timidly, ending up almost invisible. Also,
there's no useful introduction to what this "qapi" when you enter this
section.
Maybe create a "API reference" section, explaining it first?

Respectfully, "DO NOT MERGE" is written in large capital letters in the
subject of this patch.
You are free to try to format the manual as you please at a later date,
but it's not something that I will be doing right now. The purpose of
this patch is solely to prove that my docstring formatting adheres to
some kind of standard, and the method to prove it is nontrivial, hence
these patches.

This is a minor re-work of the entrypoint script. It isolates a
generate() method from the actual command-line mechanism.
The regex match error checking was modified slightly to check that we
actually got a regex match.

As part of delinting and adding type hints to the QAPI generator, it's
helpful for the entrypoint to be part of the package, only leaving a
very tiny entrypoint shim outside of the module.

All of the QAPI include statements are changed to be package-aware, as
explicit relative imports.
A quirk of Python packages is that the name of the package exists only
*outside* of the package. This means that to a module inside of the qapi
folder, there is inherently no such thing as the "qapi" package. The
reason these imports work is because the "qapi" package exists in the
context of the caller -- the execution shim, where sys.path includes a
directory that has a 'qapi' folder in it.
When we write "from qapi import sibling", we are NOT referencing the folder
'qapi', but rather "any package named qapi in sys.path". If you should
so happen to have a 'qapi' package in your path, it will use *that*
package.
When we write "from .sibling import foo", we always reference explicitly
our sibling module; guaranteeing consistency in *where* we are importing
these modules from.
This can be useful when working with virtual environments and packages
in development mode. In development mode, a package is installed as a
series of symlinks that forwards to your same source files. The problem
arises because code quality checkers will follow "import qapi.x" to the
"installed" version instead of the sibling file and -- even though they
are the same file -- they have different module paths, and this causes
cyclic import problems, false positive type mismatch errors, and more.
It can also be useful when dealing with hierarchical packages, e.g. if
we allow qemu.core.qmp, qemu.qapi.parser, etc.

Wildcard includes become hard to manage when refactoring and dealing
with circular dependencies with strictly typed mypy.
flake8 also flags each one as a warning, as it is not smart enough to
know which names exist in the imported file.
Remove them and include things explicitly by name instead.

While we're mucking around with imports, we might as well formalize the
style we use. Let's use isort to do it for us.
force_sort_within_sections: Intermingles "from x" and "import x" style
statements, such that sorting is always performed strictly on the module
name itself.
force_grid_wrap=4: Four or more imports from a single module will force
the one-per-line style that's more git-friendly. This will generally
happen for 'typing' imports.
multi_line_output=3: Uses the one-per-line indented style for long
imports.
include_trailing_comma: Adds a comma to the last import in a group,
which makes git conflicts nicer to deal with, generally.

Line is rather long for my taste.
So far, we didn't even try to have a consistent Python style in QEMU, so
I've enforced a consistent style I like within QAPI.
Having a consistent Python style in QEMU would be worth letting go of
personal preferences. Do you intend to pursue it?

isort offers to actually edit your files for you, it isn't just a
checker, it actually rewrites.
By default, it leaves one space below imports. You can configure it to
add two. I didn't really have a strong preference, so I left it at the
default.
I'm going to leave it at the default for now, but I can change it if you
have a preference.

78 chars and three names, so it didn't trigger the grid-wrap condition
of isort.
If you have an arbitrarily smaller number you'd like to use, I can feed
that to isort's config file. 72?

Yep, but flake8 does not complain about the first definitions that occur
below imports. Why not? I don't know.
Regardless, I can change it and fold the changes in; they won't affect
much here.

Well, on all of the cases here, it's not function or class definition
that follows, so that aspect of PEP 8 is not being violated.

Petty style guide fixes and line length enforcement. Not a big win, not
a big loss, but flake8 passes 100% on the qapi module, which gives us an
easy baseline to enforce hereafter.
A note on the flake8 exception: flake8 will warn on *any* bare except,
but pylint's is context-aware and will suppress the warning if you
re-raise the exception.

Using `pylint --generate-rcfile > pylintrc`, generate a skeleton
pylintrc file. Sections that are not presently relevant (by the end of
this series) are removed leaving just the empty section as a search
engine / documentation hint to future authors.
I am targeting pylint 2.6.0. In the future (and hopefully before 5.2 is
released), I aim to have gitlab CI running the specific targeted
versions of pylint, mypy, flake8, etc in a job.
2.5.x will work if you additionally pass --disable=bad-whitespace.
This warning was removed from 2.6.x, for lack of consistent support.
Right now, quite a few modules are ignored as they are known to fail as
of this commit. modules will be removed from the known-bad list
throughout this and following series as they are repaired.
Note: Normally, pylintrc would go in the folder above the module, but as
that folder is shared by many things, it is going inside the module
folder (for now). Due to a bug in pylint 2.5+, pylint does not
correctly recognize when it is being run from "inside" a package, and
must be run *outside* of the package.
Therefore, to run it, you must:

Code style tools really dislike the use of global keywords, because it
generally involves re-binding the name at runtime which can have strange
effects depending on when and how that global name is referenced in
other modules.
Make a little indent level manager instead.

At this point, that just means using a consistent strategy for constant names.
constants get UPPER_CASE and names not used externally get a leading underscore.
As a preference, while renaming constants to be UPPERCASE, move them to
the head of the file. Generally, it's nice to be able to audit the code
that runs on import in one central place.

Annotations do not change runtime behavior.
This commit *only* adds annotations.

As docstrings, they'll show up in documentation and IDE help.
The docstring style being targeted is the Sphinx documentation
style. Sphinx uses an extension of ReST with "domains". We use the
(implicit) Python domain, which supports a number of custom "info
fields". Those info fields are documented here:
https://www.sphinx-doc.org/en/master/usage/restructuredtext/domains.html#info-field-lists
Primarily, we use `:param X: descr`, `:return[s]: descr`, and `:raise[s]
Z: when`. Everything else is the Sphinx dialect of ReST.
(No, nothing checks or enforces this style that I am aware of. Sphinx
either chokes or succeeds, but does not enforce a standard of what is
otherwise inside the docstring. Pycharm does highlight when your param
fields are not aligned with the actual fields present. It does not
highlight missing return or exception statements. There is no existing
style guide I am aware of that covers a standard for a minimally
acceptable docstring. I am debating writing one.)

Including it in common.py creates a circular import dependency; schema
relies on common, but common.build_params requires a type annotation
from schema. To type this properly, it needs to be moved outside the
cycle.

Fix two very minor issues, and then establish a mypy type-checking
baseline.
Like pylint, this should be run from the folder above:
> mypy --config-file=qapi/mypy.ini qapi/
This is designed and tested for mypy 0.770 or greater.

The edge case is that if the name is '', this expression returns a
string instead of a bool, which violates our declared type.

Annotations do not change runtime behavior.
This commit *only* adds annotations.

Make the file handling here just a tiny bit more idiomatic.
(I realize this is heavily subjective.)
Use exist_ok=True for os.makedirs and remove the exception,
use fdopen() to wrap the file descriptor in a File-like object,
and use a context manager for managing the file pointer.

'fp' and 'fd' are self-evident in context, add them to the list of OK
names.
_top and _bottom also need to stay standard methods because some users
override the method and need to use `self`. Tell pylint to shush.

From: Eduardo Habkost <ehabkost@redhat.com>
The typing of _make_tree and friends is a bit involved, but it can be
done with some stubbed out types and a bit of elbow grease. The
forthcoming patches attempt to make some simplifications, but having the
type hints in advance can aid in review.

_make_tree might receive a dict or some other type. Adding features
information should arguably be performed by the caller at such a time
when we know the type of the object and don't have to re-interrogate it.

Returning a *something* or a Tuple of *something* is hard to accurately
type. Let's just always return a tuple for structural consistency.
Instances of the 'TreeNode' type can be replaced with the slightly more
specific 'AnnotatedNode' type.

This replaces _make_tree with Node.__init__(), effectively. By creating
it as a generic container, we can more accurately describe the exact
nature of this particular Node.
