Default value for ArgGroup

[b1rger]

Is it possible to provide a default value for an ArgGroup? In carl I would like to have an ArgGroup containing multiple "actions" (--agenda, --calendar, --year-progress, ...multiple(true)) and if no action is given, it should fall back to --calendar

At this time, no.

#2621 will allow the derive to specify these as an enum. You could wrap that in a Option and then unwrap_or_default.
