filename_regex

Basename matches a regex. Use stem: true to match the stem only.

Options

Option	Type	Required	Default	Description
`pattern`	string	yes		Rust regex, automatically anchored with ^…$ by the engine.
`stem`	boolean		`false`	Match the file stem (no extension) instead of the full basename.

Plus the common paths, level, id, and when fields. This table is generated from the JSON Schema; option types and defaults are authoritative.

Example

A test file whose name ignores the required `test_` prefix

The rule fires on this repository:

tests/
tests/BadNamingHere.rs
tests/test_lexer.rs
tests/test_parser.rs

With this .alint.yml:

version: 1
rules:
  - id: tests-named-test-prefix
    kind: filename_regex
    paths: "tests/**/*.rs"
    pattern: "^test_[a-z0-9_]+$"
    stem: true
    level: error

alint check reports:

--- tests/BadNamingHere.rs -----------------------------------------------------
  x  error    tests-named-test-prefix
              filename stem "BadNamingHere" does not match /^test_[a-z0-9_]+$/

Summary (1 violation):
  x 1 error
  0 passing * 1 failing

Every test file name matches the required `test_` prefix

This repository is compliant:

tests/
tests/test_eval_123.rs
tests/test_lexer.rs
tests/test_parser.rs
