lintel 0.0.1

Validate JSON and YAML files against JSON Schema
lintel-0.0.1 is not a library.

Lintel

Schema validation for your entire repo.

CI crates.io

Lintel validates JSON, YAML, and TOML files against JSON Schema in a single command. It auto-discovers schemas via SchemaStore, inline $schema properties, and YAML modelines — zero config required.

Lintel is fast. Written in Rust with no async runtime, deterministic schema caching, and pre-compiled SchemaStore catalog matching. Warm runs are pure computation.

Lintel is a drop-in CI check. Machine-parseable output, nonzero exit codes on failure, .gitignore-aware file walking. Add one line to your pipeline and catch config mistakes before they ship.

Installation

cargo install lintel

Usage

# validate with rich terminal output
lintel check

# validate with CI-friendly one-error-per-line output
lintel ci

Documentation

Lintel auto-discovers schemas in priority order: YAML modeline (# yaml-language-server: $schema=...), inline $schema property, then SchemaStore catalog matching by filename. Files without a matching schema are silently skipped.

Lintel respects .gitignore — node_modules, target/, and build artifacts are skipped automatically.

Lintel supports project configuration via lintel.toml for exclude patterns and per-repo customization.

Lintel doesn't require Node.js to function.
