jonquil Module

Public API for Jonquil - JSON parser and serializer for Fortran.

This module provides the main entry point for working with JSON data in Fortran. It re-exports types and procedures from TOML Fortran with JSON-appropriate naming, enabling seamless interoperability between JSON and TOML data structures.

Quick Start

use jonquil
class(json_value), allocatable :: val
type(json_error), allocatable :: error

! Parse JSON from a string
call json_loads(val, '{"key": "value"}', error=error)

! Serialize back to JSON
print '(a)', json_serialize(val)

Main Types

• json_object - JSON object (key-value mapping), see toml_table
• json_array - JSON array, see toml_array
• json_value - Base type for all JSON values, see toml_value
• json_error - Error information from parsing/serialization, see toml_error

Main Procedures

• json_load / json_loads - Parse JSON from files or strings
• json_dump / json_dumps - Serialize to files or strings
• json_serialize - Serialize and return as string
• get_value / set_value - Access and modify values, see get_value and set_value
