axl is a Rust workspace for accessibility linting of JSX/TSX code.

Current v0.2 focus:

• runnable CLI (axl_cli)
• parser/discovery pipeline (axl_parser)
• shared diagnostics/rule engine interfaces (axl_core)
• initial ARIA/name/focus rules (axl_rules, axl_aria)
• early contrast and pattern analysis scaffolding (axl_contrast, axl_patterns)

• axl_cli: command line entry point and output formatting
• axl_parser: TSX/JSX target collection and OXC parse validation
• axl_core: shared lint data model (Diagnostic, Rule, Severity, etc.)
• axl_aria: ARIA role and accessible-name helpers
• axl_rules: active lint rules and rule registry
• axl_config: axl.config.json loading
• axl_contrast: WCAG contrast math and color helpers (scaffold)
• axl_patterns: UI pattern detector API + dialog placeholder (scaffold)

Requirements:

• Rust toolchain (cargo)

Run checks:

cargo test

Detailed docs:

• docs/testing.md
• docs/publishing.md

Lint current directory:

cargo run -p axl_cli -- .

JSON output:

cargo run -p axl_cli -- . --format json

Filter categories:

cargo run -p axl_cli -- . --only roles,naming,focus

Use explicit config path:

cargo run -p axl_cli -- src --config axl.config.json

Apply basic autofix (currently focus/tabindex-positive only):

cargo run -p axl_cli -- . --fix

• roles/abstract-role-usage (error)
• naming/empty-accessible-name (error)
• focus/tabindex-positive (warning)

axl loads axl.config.json by default (or the file from --config).

Supported top-level fields (minimal v0.1 support):

• extends: string array
• components: object map
• rules: object map
• ignore: glob patterns to skip files

Example:

{
  "extends": ["recommended"],
  "components": {
    "Link": "a"
  },
  "rules": {
    "focus/tabindex-positive": "warn"
  },
  "ignore": ["**/*.test.tsx"]
}

• no full AccName 1.2 implementation
• no context-dependent implicit role algorithm
• no CSS parsing/resolution
• no cross-file component tree analysis
• limited autofix scope (currently focus/tabindex-positive only)
