Special Type Options

Configuration settings with special behavior or details.

AdditiveArgs

Special type for some settings that accept multiple values as input (lists or sets). When passing values as CLI arguments, if the first value is +, any value after it will be added to the values specified in the config file instead of overriding it. Similarly, if the first value is -, any value after it will be removed from the values specified in the config

Examples

If you have the following skip_hosts setting in you config file:

skip_hosts:
  - drive.google.com
  - youtube.com
  - facebook.com

You will get the following results:

Value you used	Value CDL interpreted	Details
--skip-host instagram.com	[instagram.com]	config values were overridden by CLI values
--skip-host "+" instagram.com	[drive.google.com, youtube.com, facebook.com, instagram.com]	config values and CLI values were merged
--skip-host "-" drive.google.com youtube.com	[facebook.com]	CLI values were removed from the config values

Always use quotes for "+" and "-" to make sure your shell does not try to parse them as additional flags

BoolFlag

A special kind of bool. Within a config file, it can have a true or false value. However, when used via CLI, the value is assumed from the flag name. The normal name is true, and prefixing the name with --no means false.

Examples

Value you used	Value CDL interpreted
--auto-dedupe	auto-dedupe: true
--no-auto-dedupe	auto-dedupe: false

ByteSize

A special kind of int that accepts suffixes like GB, MiB and KB

In conformance with IEC 80000-13 Standard, 1KB means 1000 bytes, and 1KiB means 1024 bytes. In general, including a middle 'i' will cause the unit to be interpreted as a power of 2, rather than a power of 10.

Examples

Value you used	Value CDL interpreted
1GB	1.000.000.000 bytes
512	512 bytes
1MiB	1.048.576 bytes

ByteSize is also used for some settings to specify speed and it's interpreted as <value> / second. ex: 8MB means 8MB/s
