Configuration Files

Configuration files use JSON format. Each component <name> (for example vision) has its configuration in root["<name>"]. Other names than <name> are not used for that component.

Using multiple configuration files is supported. If two (or more) configuration files have same keys, last loaded file sets the final values (Q: Are both objects and arrays merged?). Configuration files are included in following order, later files replace values set earlier:

1. /local/share/ftl/config.json
2. ~/.config/ftl/config.json
3. ./config.json
4. config.json files found in path(s) in argument(s)
5. Config file path provided in --config argument

Configuration values set in command line parameters override configuration file values.

Configuration structure is not fixed (yet). For reference, see common/config/config.json.
