* wheel versions now replace `+` with `.post` to match spec at https://packaging.python.org/en/latest/specifications/version-specifiers/
* CI updates:
* Bump action versions
* Disabled Windows for now and documented why
* Added a new job to upload all wheels
* Added new variable, `PYPI_INDEX`: fallback 'https://pypi.org/' if unset
* Added new secret, `PYPI_TOKEN`
* .editorconfig now uses 2 spaces for YML (it kept setting mine to tabs
and GitHub Actions doesn't like that)
* Update manylinux images
* FFI now built as a per-platform static library
* Explicitly set minimum macOS deployment target, use clang on macOS
* Try enabling Windows (as an experiment)
* Disable aarch64-linux, aarch64-windows
* Created `setup.py`: Python package manifest to build `pyosys` wheels with a custom extension to build and include `libyosys.so` using Make
* `.gitignore`: Added byproducts of the Python wheel build process
* `Makefile`: Added `-undefined dynamic_lookup` to `libyosys.so` so missing symbols can be resolved by importing into a Python interpreter
* `kernel/yosys.cc`: Gated `PyImport_AppendInittab` with `!Py_IsInitialized`; as of Python 3.12, the interpreter is already initialized and `PyImport_AppendInittab` would cause an exception to be raised
* Created `wheels.yml`: CI workflow for building wheels for CPython on:
* Linux (glibc, musl) and Darwin
* x86-64 and arm64
Add `$(TARGETS)` for gen_examples and gen_images since they need the `yosys` executable.
Add guidelines source files as a prerequisite to docs/source/generated while we're at it.
- remove the tidy target from the main target.
* aux/log file are already excluded in a .gititgnore file
* allow parallel generation as the tidy target imposes sequential build
* Less brittle method of adding script dirname to sys.path
* Check if scriptfp successfully opens before using it
* Move `log_error` to after `PyErr_Print()` is called
This matches the behavior of running a Python interpreter, where the
first element of sys.path is the dirname of the script being run.
This allows importing of files and modules in the same directory without
messing with PYTHONPATH or similar.
This adds a Python equivalent to the `-c` option, where scripts importing `libyosys` can be imported and used.
Most of the work for this was already done to enable Python passes a couple years back, so this is a relatively small changeset.
