NAME

json_foreach - function for streaming json parsing

SYNOPSIS

json_foreach
json_foreach_handler type value
json_get_last_name retvar
json_get_full_name retvar [separator]

DESCRIPTION

json_foreach

The function consumes standard input to parse JSON and calls `json_foreach_handler` for each simple value (`string`, `number`, `boolean` and `null`).

json_foreach_handler

The function is a callback that is called for each JSON value. The function receives the value type and the JSON value of the variable as arguments. Inside the callback, you can get the field name by calling the `json_get_last_name` or `json_get_full_name`.

json_get_last_name

This is a helper that is meant to be called from the `json_foreach_handler`. It puts into the `retvar` with the name of JSON field.

json_get_full_name

Same as `json_get_last_name` but returns full JSON field name. The name is made up of the parent names of the fields joined with a `separator`.
