Gates - Quality Validation (v2.37)

Comprehensive quality validation across 9 programming languages with **TLDR-assisted analysis**.

Quick Start

```bash

/gates # Run all quality gates

ralph gates # Via CLI

ralph gates src/ # Specific directory

```

Pre-Gates: TLDR Language Detection (v2.37)

**AUTOMATIC** - Detect project languages efficiently:

```bash

Get codebase structure to detect languages (95% token savings)

tldr structure . > /tmp/project-structure.md

From structure, identify:

- Primary language(s)

- Config files present

- Test frameworks used

```

Supported Languages

| Language | Linter | Formatter | Types |

|----------|--------|-----------|-------|

| TypeScript | ESLint | Prettier | tsc |

| JavaScript | ESLint | Prettier | - |

| Python | Ruff | Black | mypy |

| Rust | Clippy | rustfmt | cargo check |

| Go | golint | gofmt | go vet |

| Java | Checkstyle | google-java-format | - |

| Ruby | RuboCop | - | Sorbet |

| PHP | PHP_CodeSniffer | php-cs-fixer | PHPStan |

| Solidity | Solhint | prettier-solidity | - |

Workflow

1. Detect Languages

```bash

Auto-detect based on file extensions and config files

```

2. Run Linters

```bash

Per-language linting

npx eslint src/ # TypeScript/JavaScript

ruff check . # Python

cargo clippy # Rust

golangci-lint run # Go

```

3. Check Formatting

```bash

npx prettier --check . # JS/TS

black --check . # Python

rustfmt --check src/ # Rust

gofmt -l . # Go

```

4. Type Checking

```bash

npx tsc --noEmit # TypeScript

mypy . # Python

cargo check # Rust

go vet ./... # Go

```

5. Run Tests

```bash

npm test # Node projects

pytest # Python

cargo test # Rust

go test ./... # Go

```

Exit Codes

| Code | Meaning |

|------|---------|

| 0 | All gates passed |

| 1 | Lint errors |

| 2 | Format errors |

| 3 | Type errors |

| 4 | Test failures |

Gate Configuration

Minimal (fast)

```bash

ralph gates --minimal # Lint only

```

Standard (default)

```bash

ralph gates # Lint + Format + Types

```

Full (CI)

```bash

ralph gates --full # Lint + Format + Types + Tests

```

Integration

TLDR Integration (v2.37)

| Phase | TLDR Command | Purpose |

|-------|--------------|---------|

| Language detection | `tldr structure .` | Identify languages |

| Error context | `tldr context $FILE .` | Understand failing code |

| Impact analysis | `tldr deps $FILE .` | Find related tests |
