The previous commits have put rules for linting and formatting via
ruff, yapf, mypy and pyright into place. They are checked with the
make check target, and this commit adds the fixes for the target to
succeed.
It does some refactoring where type checking dug up dirty bits, and
also adds lots of churn in the Python code. To a good deal, that's
owed to mere formatting changes. It would have been better to
seperate those from syntax and refactoring fixes into multiple
commits, so that the interesting changes don't drown in the
formatting nose. However, that would have been a lot of additional
work only to be thrown away by later commits, hence this commit has a
big diff in one piece. The size of the diff is regrettable but
hopefully a one-off: What it buys is automatic format checking for CI
and predictble formats for smaller diffs in the future.
Rules that "make check" enforces are, in the following order
- Syntax checkers:
- ruff check .
- mypy .
- pyright
- Format check:
- yapf --diff --recursive .
The refactoring includes:
- Turn the Result class into a more elaborate object, capable of
doing more heavy lifting around stderr and stdout decoding,
summarizing outcome, and matching error strings.
Aside from fixing broken type checks, this also removes lots of
boilerplate calling code which is currently used for handling
possible call outcome scenarios. Trying to access an inexistent,
decoded string should raise a meaningful exception by itself now,
which removes lots of code with case distinctions.
- Fix Cmd type hierarchy:
- Add the AbstractCmd class above Cmd. This is necessary because
the checker rightfully complains it can't instantiate a Cmd
instance where constructor arguments were needed. They never
were, but the type used at the instantiating code's location in
jw.pkg.App so claims.
- Lots of sub- and sub-subcommands are derived from the base
class of the invoking command. That provides some properties
shared across the ancestor hierarchy of a command, but is
semantically unsound. Fix that by introducing jw.pkg.BaseCmd
class as a place to provide basic helpers shared across all
commands used in a jw.pkg.App's context, and derive all command
classes from that afresh. The parent command is still reachable
via a common parent property.
Formatting changes are conforming to PEP-8, mostly, with minor
tweaks. All in all they include the following changes.
- Remove # -*- coding: utf-8 -*-
The line was needed by Python 2 which is not supported anylonger.
For Python 3, the default encoding is UTF-8, anyway.
- Allow to run "make py-format" without having it produce any
changes. It's basically "yapf --in-place --recursive ." with some
code style settings, see conf/topdir/pyproject.toml. The settings
may be debatable. I've had custom tweaks in place on that target,
too, but then again, IDEs would have more hassle to integrate
that.
- Introduce a 88 character line length limit
- One import per line, reshuffle them semantically, see
[tool.isort] in pyproject.toml.
- Hide imports needed for type-checking only behind
if TYPE_CHECKING
- Spaces around assignments accounts for much churn. Having having
no spaces in inline parameter list assignments and default
parameter values would arguably be more compact where it's
useful. On the other hand, I have not found a code formatter
which allows spaces around assignments in parameter lists broken
into one per line and that's often better than a wall of text.
- Add two spaces before # export, as this seems to be mandated by
PEP-8
- Use single quotes by default

Add a file to be included from every toplevel Makefile of every repo
that owns Python code. It defines the following targets:
py-check: py-check-syntax py-check-format
py-check-syntax:
py-check-format:
py-format:
Currently, only mypy is run from py-check-syntax, but the targets are
meant as entry point for further linter jobs in the future.
There's also
py-format-assignments:
which is meant to add spaces around "=" in multi-line assignment
blocks, but, pending future experiments, I thing that target is going
to be removed again. Left in for now.

Add py-ns-dir.mk. It's first intended use is inside the
$(TOPDIR)/src/python/jw directories of each package. These are to be
treated specially, because they contribute to the same namespace: jw.
This is true when installed, which means that no __init__.py should
be packaged from that directory, see the guide linked below.
And it's also true when not installed, in which case there has to be
a path-extending __init__.py in the directory. Normally, it should
work without __init__.py in that case, as well, and it does for
running Python code with PYTHONPATH pointing to the respective
package roots. However, pyright doesn't seem to pull in code
scattered over multiple locations without an old-style namespace
path-extender, so we're likely going to add (but not install) an
__init__.py there.
Not sure if it's going to be auto-generated py py-ns-dir.mk or
committed to version control, we'll see with more testing.
Here's where I have my info from, aside from experiments.

If $(wildcard py.typed) is found in a python module directory,

installed to <site-dir>/jw/jw-pkg/py.typed.

Add generic machinery to dynamically create files in $(TOPDIR). The
need arises because version controlled configuration files for
linters are going to be introduced.
For that, this commit introduces a variable $(TD_GENERATE_FILES),
which target all depends on, and which topdir.clean removes.
It defaults to another variable also introduced by this commit,
$(TD_COPY_FILES), which in turn defaults to $(TOPDIR)/conf/topdir.
This commit also adds support for JW_PKG_TOPDIR_COPY_PATH. It
supports a PATH-style syntax, which allows pointing to multiple
directories to be checked for source files. If they exist, they will
be appended to the files found in $(TOPDIR)/conf/topdir after
copying. Defining arbitray files to copy is not supported before
security implications during CI runs are better understood.
Having the copy prerequisites work comes at the cost of having to add
.SECONDEXPANSION. Since it's limited to the toplevel Makefile, I
suppose that's acceptable.

Add tmpl_render(), a function to provide a primitive template
renderer. It takes a dictionary for values to replace variables
shaped {some-variable} in templates found by their name. For now, the
templates are defined in the templates module instead of being read
from a template directory. The values may be lists, in which case
they are rendered with a delimiter, defaulting to ",".
Using an existing template engine like jinja2 is tempting but would
introduce additional dependencies jw-pkg is trying hard to avoid.

Add a sub-module for code that's too specific to jw.pkg.cmds.projects
to go into jw.pkg.lib but too generic to go into a command module.
Long-term, it might be a good idea to create a place for code which
jw-pkg doesn't exclusively use for its own purposes. jw.lib, for
example. Then, liberated from the burden to be generally useful also
externally, jw.pkg.lib might be a better fit for code currently in
jw.pkg.cmds.xxx.lib, and a more natural place usable across
subcommands.

Not all __init__.py modules are generated by python-tools.sh, some
are needed early to make jw-pkg useful without generation, notably in
jw.pkg.cmds.
Add detect_modules() to unify that detection, and place it into a
minimal module lib.init to not increase startup time cost.
Signed-off-by: Jan Lindemann <jan@janware.com>
The __init__.py files as gnerated by python-tools.sh contain multiple
issues, fix them:
- Make the machinery fail if the same type name is imported from
different modules
- Support relative imports from .Module import Module instead of
having to use the entire module path as import source
- Import types explicitly re-exported with "as":
from .Module import Module as Module
Otherwise ruff will regard the type as "imported but not used"
- Add "# ruff: noqa: E501" near the top. The import lines can get
long and are beyond manual control (except for renaming the
modules themselves, that is). This can cause ruff to fail, so get
it to accept long lines in __init__.py. The style violation
doesn't make much of a difference in generated code, anyway,
because nobody reads that. Plus what's happening in the code
isn't rocket science, so good style wouldn't help much with
understanding, either.
This promptly digs up two symbol name conflicts lib.pm.dpkg and
lib.pm.rpm. Fix them along with this commit to keep it from breaking the build.

Add get-pub for top directory / projects directory level. This is a
janware specific target needed for CI. It integrates the current
master branch from the new Forgejo-based Git repos.
That said, this will likely need to go along with other release
machinery. Packaging is good, but releasing over a bunch of
directories is an intricate process, as-is only usable by janware
itself, and doesn't need to be part of jw-pkg.

If a project is not initialized via make pkg-init-%, it doesn't
contain a VERSION file. When CI tries to build and package such a
project, it auto-creates a VERSION file, but a broken one: The
revision isn't properly seperated by a dash but by a dot, which makes
CI give up while parsing it.

Currently, completing a release works with a plain git push. It may
push to several repos, depending on how the client repo's origin's
pushurl is configured. Those repos may have different user names, and
if the ssh wrapper added -l via JW_PKG_SSH_EXTRA_OPTS, the push would
fail. Hence, disable JW_PKG_SSH_EXTRA_OPTS for that case.
