jsondec: JSON Decode

In secretbase: Cryptographic Hash, Extendable-Output and Binary/Text Encoding Functions

JSON Decode

Description

Minimal JSON parser. Converts JSON to R objects with proper type handling.

Usage

jsondec(x)

Arguments

x	Character string or raw vector containing JSON data.

Details

This is a minimal implementation designed for parsing HTTP API responses.

Value

The corresponding R object, or an empty list for invalid input.

Type Mappings

• Object {} -> named list

• Array ⁠[]⁠ -> unnamed list

• String -> character

• Number -> numeric

• true/false -> logical

• null -> NULL

RFC 8259 Non-conformance

• Invalid JSON returns an empty list instead of erroring.

• Duplicate keys are preserved; R accessors ($, [[) return first match.

• Non-standard number forms may be accepted (e.g., leading zeros, hexadecimal).

• Invalid escape sequences are output literally (e.g., ⁠\\uZZZZ⁠ becomes "uZZZZ").

• Incomplete Unicode escape sequences for emoji are tolerated.

• Nesting depth is limited to 512 levels.
