4.1 IUSE structs
struct
(struct piuse (default flag) #:extra-constructor-name make-piuse #:transparent) default : piuse-default? flag : string?
Example:
> (piuse 'enabled "wayland") (piuse 'enabled "wayland")
struct
(struct piuses (iuses) #:extra-constructor-name make-piuses #:transparent) iuses : (listof iuse?)
4.2 IUSE helper functions
procedure
(piuse-default? v) → boolean?
v : any
Examples:
> (piuse-default? 'disabled) #t
> (piuse-default? 'enabled) #t
> (piuse-default? #false) #t
> (piuse-default? "asd") #f
4.3 IUSE conversion
procedure
(piuse-default->string a-piuse-default) → string?
a-piuse-default : piuse-default?
Example:
> (piuse-default->string 'enabled) "+"
procedure
(piuse->string a-piuse) → string?
a-piuse : piuse?
Example:
> (piuse->string (piuse 'enabled "wayland")) "+wayland"
procedure
(piuses->string a-piuses) → string?
a-piuses : piuses?
Example:
> (piuses->string (piuses (list (piuse 'enabled "wayland")))) "+wayland"
procedure
(string->piuse a-string) → piuse?
a-string : string?
Example:
> (string->piuse "+wayland") (piuse 'enabled "wayland")
procedure
(string->piuses a-string) → piuses?
a-string : string?
Example:
> (string->piuses "+wayland") (piuses (list (piuse 'enabled "wayland")))
