Support for multi-line tables in `pyproject.toml`

[patrick91]

I do have a few per-file ignores in my project[1]. Do you think it is possible to add support for multi-line tables?

This works:

[tool.ruff]
line-length = 89
per-file-ignores = {"tests/federation/printer/*" = ["E501"], "tests/test_printer/test_basic.py" = ["E501"], "tests/pyright/test_federation.py" = ["E501"], "tests/test_printer/test_schema_directives.py" = ["E501"]}

This does not:

[tool.ruff]
line-length = 89
per-file-ignores = {
  "tests/federation/printer/*" = ["E501"], 
  "tests/test_printer/test_basic.py" = ["E501"], 
  "tests/pyright/test_federation.py" = ["E501"], 
  "tests/test_printer/test_schema_directives.py" = ["E501"]
}

Error:

error expected a table key, found a newline at line 196 column 21

I get the same error in VS Code:

My understanding is that multi-line tables are supported by TOML: toml-lang/toml#904

but it's a relatively new feature :)

Anyway, I'm fine with having the ignores on one line, it's not a big deal, I opened the issue just in case it is easy to implement and for others that might stumble on the same problem :)

I'm not an expert in TOML and how tables work, but I ran into this problem in a project too. You can use the following syntax for this at the moment:

[tool.ruff.per-file-ignores]
"tests/federation/printer/*" = ["E501"]
"tests/test_printer/test_basic.py" = ["E501"]
"tests/pyright/test_federation.py" = ["E501"]
"tests/test_printer/test_schema_directives.py" = ["E501"]

It doesn't look to me like the PR your linked has been published under a new TOML version, so for now the spec doesn't allow these kinds of tables.

ah! great suggestion!

didn't notice that! thanks for checking 😊

I'll close the issue for now then!

It ain't pretty, but I like one section per tool. The following works, which is good enough for me.

[tool.ruff]
per-file-ignores = {"btrack/models.py" = [
    "UP006",
    "UP007",
], "btrack/config.py" = [
    "UP006",
    "UP007",
]}
