Preserve Multiline Formatting for Complex Query Chains

[zbambusek]

I'm finding that ruff currently condenses multiline chained statements, which can negatively impact readability in the following case:

query = select(DocumentsFiles.files_id)
    .where(DocumentsFiles.files_id.isnot(None))
    .order_by(desc(DocumentsFiles.id))

formats to:

query = select(DocumentsFiles.files_id).where(DocumentsFiles.files_id.isnot(None)).order_by(desc(DocumentsFiles.id))

The example that you shared isn't valid but I suspect you meant

query = (
    select(DocumentsFiles.files_id)
    .where(DocumentsFiles.files_id.isnot(None))
    .order_by(desc(DocumentsFiles.id))
)

Ruff does keep the above formatting if putting the entire chain on a single line exceeds the configured line length.

Thanks, this was about having an option to set an exception for the alchemy specific queries.
Reducing line length would indeed resolve the issue, but that would affect the rest of the code.

This is just a suggestion.

The issue with never collapsing is that it makes formatting non-reversible which is a rather important property. Reversability
ensures that a change made by the formatter is "undone" when the code changes. In this specific context:

• The formatter inserts the parentheses if the line gets too long
• The reversability guarantees that the formatter removes the parentheses again if you shorten the call chain.
