The __find_circular_deps() and find_circular_deps() methods now return list[str] instead of bool. On a cycle, the path builds up the dependency chain in __find_circular_deps_recursive(), and __find_circular_deps() appends the closing project to complete the cycle. An empty list means no cycle found.
CmdDep prints the cycle as 'a -> b -> c -> a' instead of a generic message.

Relabel the toplevel command CmdPkg from "pkg" to "packages", because it rolls off the tounge much more nicely. Keep "pkg" as an alias for compatibilty.
Add a property aliases to AbstractCmd in prepeparation for commands to bear multiple names / abbreviations / aliases.
The App.add_cmds_to_parser() function uses parse_known_args() to determine which subcommand was invoked, then conditionally registers nested subcommands. The lookup dictionary (scs) contains only canonical names, not aliases, so add them too, otherwise using the alias instead of the canonical name causes the lookup to fail and nested subcommands to never be registered.
Fix: Register each alias in scs pointing to the same SubCommand object, and deduplicate with id(sc) when iterating in all=True mode to avoid infinite recursion on help output.
Support a --delimiter option to the ldlibpath and exepath commands. Notable use case are the JW_PKG_XXX_PATH variables, which should use spaces instead of colons.
TODO: Merging those two command modules with BaseCmdPkgRelations would have made introducing this redundancy unnecessary, check if that's a possibility.
Some options to the pkg-xxx commands, like flavour, --subsections and --ignore understand a comma as delimiter if multiple option values are specified. The comma character is not very friendly to use in $(call ...) macros, though, so support spaces and pipe characters as well.
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.
- 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.
- 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.
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.
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.
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.
Exceptions raised by the build command are handled and changed, messing up the stack trace. Re-raise the original exception from the exception handler to fix that.
Add a module cmds.secrets.lib.tar. Secrets handling demands treating tar archive members more individually, jw.pkg.lib.TarIo is not a good fit for that, so try with a different module. To be merged eventually.
Enclose ExecContext._run() in an open() / close() - pair. This is convenient for the caller in that it doesn't need to take care of opening and closing for one call only, and inconvenient in that it forces the caller to conciously add an open() / close() - pair around multiple run() calls where it wants the context to stay open in between. Or use the ExecContext as a context manager.
There are a couple of assert statements in the codebase which can make jw-pkg fail without any detail whatsoever if --backtrace is not specified, fix that.
Add DistroContext.install(). It takes a tar file containing secrets, decrypts it, and installs all secrets needed on target and present in that file. For every file that should be extracted, it logs if it acutally did something or didn't.
It also features an only_missing argument, which is just a stub for "allow to define somy extraction policy with respect to replacing all / some / not replace / whatever. Not thought through.
