valuedefaultOptions :: SharedOptions

valueisDefault

:: Eq a
=> (SharedOptions -> a)
Option field name.
-> SharedOptions
Options.
-> Bool

Check whether an option is unchanged from the default.

valueprintOptions :: SharedOptions -> String

Print options as input to BNFC.

unwords [ "bnfc", printOptions opts ] should call bnfc with the same options as the current instance.
