unittest ValueError: Empty module name

[mfussenegger]

Are you opening neovim outside of the project directory?

'%:p:~:.:r:gs?/?.?' looks a bit redundandent. :p turns the path into an absolute path, :~ makes it relative to the home directory, :. makes it relative to the current directory. Those are kinda incompatible with each other.

See :help filename-modifiers

Thanks @mfussenegger .

'%:p:~:.:r:gs?/?.?' looks a bit redundandent.

Yes, %:p:~:.:r:gs?/?.? and %:.:r:gs?/?.? are returning the same results.

Are you opening neovim outside of the project directory?

No, I don't think so.

Let me use https://github.com/navdeep-G/samplemod to show the detail.

cd /Users/lds
git clone [email protected]:navdeep-G/samplemod.git
cd samplemod/sample
nvim core.py

Then use :e tests/test_basic.py to switch to the test file, and running the following command get different results:

• :echo expand('%:r:gs?/?.?') get .Users.lds.samplemod.tests.test_basic
• :echo expand('%:.:r:gs?/?.?') get tests.test_basic

If I want to get :lua require('dap-python').test_method() works fine, I think the second one is necessary.

[mfussenegger]

In your example I get tests.test_basic in both cases which is kinda the expected behavior of neovim. (Assuming you opened neovim in samplemod root, not sampelmod/sample, :e tests/test_basic.py would not work from inside the sample folder)

Are you using some kind of rooter plugin as well ?

In any case, I'd accept a PR that adds the :. to force a relative path on the working dir.

[rhinoxi]

ok, I'll try to figure out which plugin or config is causing this behavior.

[rhinoxi]

It seems like this project.nvim plugin is changing the working directory automatically, so that I can use :e tests/test_basic.py to switch when opening nvim in samplemod/sample.

But with nvim + project.nvim, both :echo expand('%:r:gs?/?.?') and :echo expand('%:.:r:gs?/?.?') will get the same result, tests.test_basic.

I got the problem with LunarVim and some custom configuration, still looking into it.

[pyright] Python files are opened using a different path than the one I typed
When customizing root_dir, buffer names end-up being absolute, but only in pyright
it seems to be a behavior of pyright.
I'll close this and send a PR.
