Files
Important
Fastfetch's config language uses JSONC, not JSON! Make sure the file extension is .jsonc.

General module options:
--<module>-format <format> Set the format string to use for each specific module
To see how a format string works, use "fastfetch -h format".
To see help about a specific format string, use "fastfetch -h <module>-format"
--<module>-key <key> Set the key to use for each specific module.
For modules which print multiple lines, the string is parsed
as a format string with the index as first character
--<module>-key-color <color> Override the global "--color-keys" option for each specific module
--<module>-key-width <num> Override the global "--key-width" option for each specific module
Parsing is not case sensitive. E.g. "--lib-PCI" is equal to "--Lib-Pci"
If a value starts with a ?, it is optional. An optional boolean value defaults to true if not specified.
More detailed help messages for each options can be printed with "-h <option_without_dash_prefix>"
All options can be made permanent with command "fastfetch <options> --gen-config"
