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 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.
Remove JW_PKG_EXTRA_SSH_OPTS before git pull in the context of get-pub / git-get-pub because it contains -l username, which collides with Forge-style git@<forge> remote URIs.
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.
Add a new target git-show-ahead-of-master, which does what git-show-pushable did up to now: List all repos where the currently checked-out branch is ahead of origin/master.
git-show-pushable now shows repos that have their checked-out branch ahead of their respective upstream branches. Which is truer to what the target's name suggests.
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.
