`json.config`

Structs

struct ParserConfig

Configuration options for JSON parsing.

Example: var config = ParserConfig(max_depth=10, allow_comments=True) var data = loads(json_str, config).

Implements Movable

Fields: max_depth: Int: Maximum nesting depth allowed. 0 = unlimited (default).; allow_comments: Bool: Allow JavaScript-style comments (// and /* */). Default: False.; allow_trailing_comma: Bool: Allow trailing commas in arrays and objects. Default: False.; ijson: Bool: Enforce I-JSON (RFC 7493). Default: False.

def __init__(out self, max_depth: Int = Int(0), allow_comments: Bool = False, allow_trailing_comma: Bool = False, ijson: Bool = False)

Create parser configuration.

Args: max_depth: Maximum nesting depth (0 = unlimited).; allow_comments: Allow // and /* */ comments.; allow_trailing_comma: Allow trailing commas.; ijson: Enforce the checkable rules of RFC 7493.

def default() -> Self

Create default (strict) parser configuration.

def lenient() -> Self

Create lenient parser configuration allowing common extensions.

def interoperable() -> Self

Create an I-JSON (RFC 7493) parser configuration.

Stricter than the default: the extensions stay off and the two checkable I-JSON rules are enforced.

struct SerializerConfig

Configuration options for JSON serialization.

Example: var config = SerializerConfig(sort_keys=True, indent=" ") var json = dumps(value, config).

Implements Movable

Fields: indent: String: Indentation string. Empty = compact output (default).; sort_keys: Bool: Sort object keys alphabetically. Default: False.; escape_unicode: Bool: Escape non-ASCII characters as \uXXXX. Default: False.; escape_forward_slash: Bool: Escape forward slashes as /. Default: False (for HTML safety).

def __init__(out self, indent: String = "", sort_keys: Bool = False, escape_unicode: Bool = False, escape_forward_slash: Bool = False)

Create serializer configuration.

Args: indent: Indentation string (empty = compact).; sort_keys: Sort object keys alphabetically.; escape_unicode: Escape non-ASCII as \uXXXX.; escape_forward_slash: Escape / as / (for HTML embedding).

def default() -> Self

Create default serializer configuration (compact output).

def pretty(indent: String = "  ") -> Self

Create pretty-print configuration with given indent.

def preprocess_json(json: String, config: ParserConfig) -> String

Preprocess JSON according to config options.

This handles:
