dir_only_contains

Every direct-child file of a directory matching select: must match at least one glob in allow:. Catches stray test data in src/.

Options

Option	Type	Required	Default	Description
allow	dir only contains allow list	yes		Basename glob(s) accepted as direct children. Anything else is a violation.
select	string	yes		Glob selecting the directories to enumerate.

Plus the common level, id, and when fields. This rule analyses the whole repository, so it takes no paths or expect_matches. This table is generated from the JSON Schema; option types and defaults are authoritative.

Example

Stray non-Rust files under src

The rule fires on this repository:

• src/
• src/a.rs✓
• src/b.rs✓
• src/notes.txt✗

  ✗ error src-only-rs

  src/notes.txt is not allowed in src (allow: [*.rs])

• src/stray.py✗

  ✗ error src-only-rs

  src/stray.py is not allowed in src (allow: [*.rs])

With this .alint.yml:

version: 1
rules:
  - id: src-only-rs
    kind: dir_only_contains
    select: "src"
    allow: ["*.rs"]
    level: error

alint check reports:

--- src/notes.txt --------------------------------------------------------------
  x  error    src-only-rs
              src/notes.txt is not allowed in src (allow: [*.rs])

--- src/stray.py ---------------------------------------------------------------
  x  error    src-only-rs
              src/stray.py is not allowed in src (allow: [*.rs])
