From type/Str
See primary documentation in context for method pred
method pred(Str: --> Str)
Returns the string decremented by one.
String decrementing is "magical" just like string increment (see succ). It fails on underflow
'b0'.pred; # OUTPUT: «a9»'a0'.pred; # OUTPUT: Failure'img002.png'.pred; # OUTPUT: «img001.png»
From type/Enumeration
See primary documentation in context for method pred
method pred(::?CLASS:)
say Freija.pred; # OUTPUT: «Oðin»
From type/Bool
See primary documentation in context for routine pred
method pred(--> Bool)
Returns False.
say True.pred; # OUTPUT: «False»say False.pred; # OUTPUT: «False»
pred is short for "predecessor"; it returns the previous enum value. Bool is a special enum with only two values, False and True. When sorted, False comes first, so False is the predecessor to True. And since False is the "lowest" Bool enum value, its own predecessor is also False.
From type/Date
See primary documentation in context for method pred
method pred(Date: --> Date)
Returns a Date of the previous day. "pred" is short for "predecessor".
say Date.new("2016-01-01").pred; # OUTPUT: «2015-12-31»
From type/Allomorph
See primary documentation in context for method pred
method pred(Allomorph:)
Calls Numeric.pred on the invocant's numeric value.
From type/IO/Path
See primary documentation in context for method pred
method pred(IO::Path: --> IO::Path)
Returns a new IO::Path constructed from the invocant, with basename changed by calling Str.pred on it.
"foo/file02.txt".IO.pred.say; # OUTPUT: «"foo/file01.txt".IO»
From type/Numeric
See primary documentation in context for method pred
method pred(Numeric:)
Returns the number decremented by one (predecessor).
