162 r"""Parse a given section into a JSON object.
163
164 Parse arbitrary key/value pairs from 'section' of the current
165 configuration into a nested JSON object.
166
167 The following rules need to be considered:
168
169 * An option's key may be declared as a series of nested dictionary keys,
170 seperated by '.'.
171 * An option's key must end with '[]', to mark this option as an array
172 * When an option is marked as an array, no other nested objects may
173 follow
174 * An array is expandable by the ConfigParser's '+=' token.
175 * Values may be marked as `number` or `bool` by prefixing them
176 accordingly:
177 * bool:<value>
178 * number:<value>
179
180 Example:
181
182 {
183 "good": false,
184 "bar": {
185 "baz": ["bar", "bazinga"]
186 foo = foo },

189 baz.z[] = b bool:true "float": 1.4
190 bar.baz[] += bazinga ==> },
191 bad = bool:true "baz": {
192 good = bool:false "foo": "a",
193 is.integer = number:1 "z": ["b", true]
194 is.float = number:1.4 },
195 "bad": true
