Example

Stray non-Rust files under src

The rule fires on this repository:

src/
src/a.rs
src/b.rs
src/notes.txt
src/stray.py

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])

Summary (2 violations):

The src directory holds only Rust files

This repository is compliant:

src/
src/a.rs
src/b.rs
src/mod.rs

With this .alint.yml:

version: 1
rules:
  - id: src-only-rs
    kind: dir_only_contains
