| config.write Writes a data field to a config file | 
| Usage | 
| config.write <id> <key> <value> | 
| Description | 
| Writes the <key>=<value> pair to the config file identifier by <id>. <id> must be a valid config file ID returned by $config.open(). <key> and <value> can be any strings. The <key>=<value> pair is written in the current section of the config file. If <key> already exists in the current section of the config, the corresponding value is replaced with <value>. If <value> is an empty string, the <key> is simply removed from the current section. If a section remains empty (with no keys) at file write time, that section will be removed. The changes are not written to disk: you must call config.flush or (better) config.close for the changes to be effectively written. |
