Core validation engine for Lintel. Validates JSON, YAML, TOML, JSON5, and JSONC files against JSON Schema.

Features

  • Multi-format parsing — JSON, YAML, TOML, JSON5, JSONC with format-specific $schema extraction (inline properties, YAML modelines, TOML header comments)
  • SchemaStore catalog — auto-matches files to schemas using SchemaStore fileMatch patterns
  • Schema caching — disk-backed cache for remote schemas with configurable cache directory
  • Project configuration — lintel.toml with exclude patterns, schema URI rewrites, //-relative paths, and per-file overrides
  • Rich diagnostics — miette-powered error reporting with source spans

Usage

use lintel_check::validate::ValidateArgs;

let args = ValidateArgs {
    globs: vec!["**/*.json".to_string()],
    exclude: vec![],
    cache_dir: None,
    force_schema_fetch: false,
    force_validation: false,
    no_catalog: false,
    config_dir: None,
    schema_cache_ttl: None,
};
// Pass args and an HttpClient implementation to validate::run()

Configuration (lintel.toml)

root = true
exclude = ["vendor/**", "node_modules/**"]

[rewrite]
"https://json.schemastore.org/" = "//schemas/"

[[override]]
files = ["**/vector.json"]
schemas = ["**/vector.json"]
validate_formats = false
  • root — stop walking up the directory tree for parent configs
  • exclude — glob patterns to skip during validation
  • rewrite — URI prefix replacement rules (longest prefix wins)
  • // paths — resolve relative to the directory containing lintel.toml
  • [[override]] — per-file/per-schema settings (e.g. disable format validation)
