Validate Model Configuration Against Schema — validate

Validates a configuration object against a JSON Schema. Returns detailed error messages if validation fails.

Usage

validate_config(config, schema, error = FALSE)

Arguments

config: Configuration to validate (list from YAML or JSON)
schema: JSON Schema to validate against (from create_config_schema())
error: If TRUE, throws an error on validation failure instead of returning a result object (default: FALSE)

Value

A list with:

valid: Logical indicating if configuration is valid
errors: Character vector of error messages (empty if valid)

If error = TRUE and validation fails, throws an error instead.

Examples

# Create a schema
schema <- create_config_schema(
  properties = list(
    n_samples = schema_integer(minimum = 1L),
    method = schema_enum(values = c("a", "b", "c"))
  ),
  required = c("n_samples")
)

# Valid configuration
config <- list(n_samples = 100L, method = "a")
result <- validate_config(config, schema)
result$valid
#> [1] TRUE
# TRUE

# Invalid configuration (missing required field)
config <- list(method = "a")
result <- validate_config(config, schema)
result$valid
#> [1] FALSE
# FALSE
result$errors
#> [1] "(root): must have required property 'n_samples'"
# Error message about missing n_samples

# Throw error on invalid config
if (FALSE) { # \dontrun{
validate_config(list(), schema, error = TRUE)
# Error: Configuration validation failed: ...
} # }
