Make the log delimiter look more consistent: Whether a CallContext was constructed with a title parameter or without, prefix its .log_delimiter property with a "----".
Remove CmdPythonpathOrig. Its only purpose has ever been to document and try out how cmd_pythonpath_orig() had worked in an ancient application version, that purpose is now served.
The global --topdir-format option governs how a project's root directory is represented in paths output by various queries. "absolute" means as absolute path, "unaltered" means verbatim as specified via --topdir, make:xyz means replaced by the string $(xyz), for later expansion in a makefile variable.
This commit adds another variant: "relative" yields the shortest possible output format of the output path in question relative to --topdir, with "shortest possible" in this context meaning canonicalized and leading "./" stripped.
Ignore newline at the end of Result.stdout_str if only one line of output is wanted from an executed shell command. The output of both uname and mktemp are used wrongly in that regard.
- Add an additional, more generic value that --format understands:
"tmpl". If chosen, the template selected by the new option
--template-name is rendered by replacing --field key=value pairs.
- This commit also adds the option --quote, which makes the
renderer enclose the rendered variable values in double quotes.
Add --search-path to the list of CmdCreateFile's supported options. Its value is split by ":" and subsequently passed to the tmpl_render()'s search_path argument.
tmpl_render()'s "values" argument currently understands dict[str,str|list[str]]. Enhance that to understand the broader RenderValues type, which also includes Iterable[tuple[str, str]], as produced by argparse.add_argument(action='append').
This commit also adds proper type-checking for the values argument. Before, its type had gone unchecked entirely.
Add an additional keyword-argument search_path to templates.tmpl_render(). It allows to specifiy a list of directory paths in which a template of a given name can be found. It defaults to [], in which case only the built-in templates are considered. Otherwise file locations are tried first, then the built-in templates.
In order to allow Pyright to check the types provided by dependant repositories without installing them, pyrightconfig.json contains a list of paths to their root directories in "extraPaths". These paths are unusable for Pyright, though: For type checking to work, it needs to be pointed to the "jw" namespace package paths within those repos. This commit achieves that by appending the subdirs src/python and tools/python to them, provided they exist.
TODO: This fix hardcodes the current project directory structure. Better would be a way to customize that via makefiles, where the paths can be more easily customized.
App.get_projects_refs() is a versatile tool, but what it does isn't obvious. Use the simpler method .get_value() instead for get_libname(), and return None if a project doesn't provide a linkable library.
- Rename variable dep and deps to val and vals, respectively,
because that's more what they are values of key-value pairs. In
some cases that can represent dependencies, in some case other
things.
- Make a scope case distinction a little clearer by mentioning all
possible cases in a match / case block
- Remove package_name and package_path from the prototype of
detect_modules(). They can and should be deduced from
namespace['__name__'] and namespace['__path__'], respectively.
- Make prefix default to None, which signifies "Don't filter by
prefix".
- Add an optional extend_namespace parameter, which will make the
function append the module's __name__ to its __path__. This
defaults to True, thereby adding a side effect to the function.
Which is always wanted in the case for all callers of this
function.
Accept if AsyncSSH is missing. The package would be nice to have, i.e. a good candidate for a "recommends" section, but until there's support for that, better be able to do without and fall back to command-line ssh.
Accept if argcomplete is missing. The package would be nice to have, i.e. a good candidate for a "recommends" section, but until there's support for that, better be able to do without.
Fix another regression of commit 6db73873e7: lib.ExecContext.CallContext.__exit__() returns True, which swallows all exceptions thrown in the context of _run() and _sudo(). Fix that.
Allow find_dir() to return None in case it couldn't find a directory, that's a legal outcome. Add a boolean parameter "throw" to support throwing an exception if the existence needs to be asserted.
It would probably be nicer for the type checkers to split this up into a throwing and non-throwing function. Postponed.

Fix a regregression breaking run_curl() / run_curl_into(), introduced by commit 6db73873e7. A missing indentation raises a non-existing Error after successful JSON parsing, fix that.
App.is_excluded_from_build() uses the wrong function entirely to query the [build.exclude] section of project.conf (App.get_project_refs() instead of App.get_value()). This has obviously never worked. It rose to prominence because commit 6db73873 introduced App.__proj_dir(), which now raises an Exception if passed garbage, which in turn surfaces as
Exception: No project path found for module "debian"
Use the correct function for that: App.get_value().
This reverts the changes commit 24928c6f did beyond mere type fixes to pkg_relations(). It looked better, but it had the output collapse to an empty list. Refactoring of that mega-function postponed.
Add an empty __init__.py in jw.pkg to version control because, before a build is through, it's needed for running jw-pkg.py from source.
Without it, with the jw now a namespace container and empty as such, as long as src/python/jw/pkg/__init__.py is not yet created by make all, /usr/lib64/python3.x/site-packages/jw/pkg will take precedence before src/python/jw/pkg. So, if jw-pkg-run is installed regularly, the source tree remains unused.
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
Add CmdCreateFile as a command to generate files from project metadata. It uses the new tmpl_render() engine, might serve as a central location to replace other code generating files, let's see how that evolves.
BaseCmdPkgRelations contains pkg_relations(), a function doing package graph analysis code. The function needs to be made available to code outside BaseCmdPkgRelations, so move it to cmds.projects.lib.pkg_relations.
The commit also applies style fixes to both BaseCmdPkgRelations and pkg_relations which anticipate broader style changes to jw-pkg in general.
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.
Lots of sub- and sub-subcommands are derived from the base class of the invoking command, notably below cmds.projects. That provides some properties shared across the ancestor hierarchy of a command, but is semantically unsound. Introduce jw.pkg.BaseCmd class as a place to provide basic helpers shared across all commands used in a jw.pkg.App's context. Also add cmds.projects.Cmd to be used by other commands in cmds.projects in later commits.
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.
