Single-file or env-only packages not allowed?

[con-f-use]

Don't actually know if it's a bug, nothing at all (because already implemented) or a feature; request.

Assuming my project to be packaged is a single file next to pyproject.toml in the file system hierarchy (i.e. in the same directory as pyproject.toml).

tree ./
./
├── myproject.py
└── pyproject.toml

can I get poetry to accept that? I.e. what does the package attribute have to look like?

[tool.poetry]
name = "myproject"
version = "0.1.0"
description = "Single file project"
authors = ["confus"]
packages = [{include = "myproject", from = "."}]   # and similar don't work

[tool.poetry.dependencies]
python = "^3.10"

[build-system]
requires = ["poetry-core"]
build-backend = "poetry.core.masonry.api"

Related: what if I just wanted to use poetry for the dependency pinning functionality, i.e. just to distribute a reliably reproducible virtual environment? Does that work? If not, consider this a issue a feature request.

You don't need to put anything special in the packages section of pyproject.toml, this Just Works.

Please close.

Can you give an example of it just working, because it doesn't for me.

Just remove packages = [{include = "myproject", from = "."}] from the pyproject.toml. Poetry will then look for a myproject and src/myproject folder. If it cannot find one, Poetry will not install the project itself in editable mode, but otherwise it's fine with this.

My apologies, seems like it's indeed looking for all three of ./myproject.py, ./myproject/ and ./src/myproject. I have no idea, why it initially didn't (I did try omitting packages in pyproject.toml before creating the issue). Maybe I typoed the filename. Thanks for your patience.

That being said, a way to omitt the project name and version (without poetry defaulting to anything) would sure be nice. Just to prevent accidentally packaging/pypi-uploading something that is not intended to be shared in that way.
