json_config()

`json_config()`#

The json_config function merges multiple JSON configuration sources into a single JSON string, allowing for variable substitution and expansion. It processes fixed, variable, file-based, and parameter-based configurations in a structured order.

C

Prototype

char *json_config(
    BOOL        print_verbose_config,
    BOOL        print_final_config,
    const char  *fixed_config,
    const char  *variable_config,
    const char  *config_json_file,
    const char  *parameter_config,
    pe_flag_t   quit
);

Parameters

Key	Type	Description
`print_verbose_config`	`BOOL`	If `TRUE`, prints the verbose configuration and exits.
`print_final_config`	`BOOL`	If `TRUE`, prints the final merged configuration and exits.
`fixed_config`	`const char *`	A fixed JSON configuration string that cannot be modified.
`variable_config`	`const char *`	A JSON configuration string that can be modified.
`config_json_file`	`const char *`	A file path containing JSON configuration data.
`parameter_config`	`const char *`	A JSON string containing additional configuration parameters.
`quit`	`pe_flag_t`	Determines the behavior on error, such as exiting or continuing execution.

Return Value

Returns a dynamically allocated JSON string containing the merged configuration. The caller must free the returned string using jsonp_free().

Notes

[‘The function processes configurations in the following order: fixed_config, variable_config, config_json_file, and parameter_config.’, ‘If print_verbose_config or print_final_config is TRUE, the function prints the configuration and exits.’, ‘The function supports variable substitution using the __json_config_variables__ key.’, ‘The JSON string can contain one-line comments using ##^.’, ‘If an error occurs in JSON parsing, the function may exit based on the quit parameter.’]
