method Str
Documentation for method Str assembled from the following types:
class StrDistance
From StrDistance
(StrDistance) method Str
Defined as:
multi method Str(StrDistance: --> Str)
Returns an after string value.
my = ( ~~ tr/old/new/);say .Str; # OUTPUT: «fnew»say ~; # OUTPUT: «fnew»
class IO::CatHandle
From IO::CatHandle
(IO::CatHandle) method Str
Defined as:
method Str(IO::CatHandle: --> Str)
Calls .Str on the currently active source handle and returns the result. If the source handle queue has been exhausted, returns an implementation-defined string ('<closed IO::CatHandle>' in Rakudo).
class IO::Handle
From IO::Handle
(IO::Handle) method Str
Returns the value of .path, coerced to Str.
say "foo".IO.open.Str; # OUTPUT: «foo»
class IO::Path
From IO::Path
(IO::Path) method Str
Defined as:
method Str(IO::Path: --> Str)
Alias for IO::Path.path. In particular, note that default stringification of an IO::Path does NOT use the value of $.CWD attribute. To stringify while retaining full path information use .absolute or .relative methods.
class IO::Special
From IO::Special
(IO::Special) method Str
method Str(IO::Special:)
This returns '<STDIN>', '<STDOUT>', or '<STDERR>' as appropriate.
class Junction
From Junction
(Junction) method Str
Defined as:
multi method Str(Junction:)
Autothreads the .Str method over its elements and returns results as a Junction. Output methods that use .Str method (print and put) are special-cased to autothread junctions, despite being able to accept a Mu type.
class Num
From Num
(Num) method Str
method Str(Int)
Returns a string representation of the number.
say π.Str; # OUTPUT: «3.141592653589793»
Cool being a parent class of Num, an explicit call to the Num.Str method is seldom needed.
say π.Str.comb == π.comb; # OUTPUT: «True»
class List
From List
(List) method Str
Defined as:
method Str(List: --> Str)
Stringifies the elements of the list and joins them with spaces (same as .join(' ')).
say (1,2,3,4,5).Str; # OUTPUT: «1 2 3 4 5»
class Code
From Code
(Code) method Str
Defined as:
multi method Str(Code: --> Str)
Will output the method name, but also produce a warning. Use .raku or .gist instead.
sub marine()say ~;# OUTPUT: «Sub object coerced to string (please use .gist or .raku to do that)marine»say .Str;# OUTPUT: «Sub object coerced to string (please use .gist or .raku to do that)marine»say .raku; # OUTPUT: «sub marine { #`(Sub|94280758332168) ... }»
role Systemic
From Systemic
(Systemic) method Str
method Str
Instance method returning the name of the object.
say .Str; # OUTPUT: «Raku»
class Match
From Match
(Match) method Str
Defined as:
method Str(Match: --> Str)
Returns the matched text.
"abc123def" ~~ /\d+/;say $/.Str; # OUTPUT: «123»
role Real
From Real
(Real) method Str
multi method Str(Real:)
Calls the Bridge method on the invocant and then the Str method on its return value.
class Thread
From Thread
(Thread) method Str
method Str(Thread: --> Str)
Returns a string which contains the invocants thread id and name.
my = Thread.new(code => , name => 'calc thread');say .Str; # OUTPUT: «Thread<3>(calc thread)»
class Nil
From Nil
(Nil) method Str
method Str()
Warns the user that they tried to stringify a Nil.
class Label
From Label
(Label) method Str
Converts to a string including the name, file and line it's been defined in.
class Mu
From Mu
(Mu) method Str
multi method Str(--> Str)
Returns a string representation of the invocant, intended to be machine readable. Method Str warns on type objects, and produces the empty string.
say Mu.Str; # Use of uninitialized value of type Mu in string context.my = [2,3,1];say .Str # OUTPUT: «2 3 1»
role Blob
From Blob
(Blob) method Str
Defined as:
multi method Str(Blob:)
Throws X::Buf::AsStr with Str as payload. In order to convert to a Str you need to use .decode.
class ForeignCode

method Str( ForeignCode: )
Returns the name of the code by calling name.
class Date
From Date
(Date) method Str
Defined as:
multi method Str(Date: --> Str)

class Version
From Version

my = v1.0.1;my = Version.new('1.0.1');say .Str; # OUTPUT: «1.0.1»say .Str; # OUTPUT: «1.0.1»
class Allomorph
From Allomorph

method Str(Allomorph:)
Returns the Str value of the invocant.
role Sequence
From Sequence
(Sequence) method Str
multi method Str(::?CLASS:)
Stringifies the cached sequence.
class Backtrace
From Backtrace
(Backtrace) method Str
Defined as:
multi method Str(Backtrace:)

my = Backtrace.new;say .Str;
class Pair
From Pair

my = eggs => 3;say .Str; # OUTPUT: «eggs 3»
class DateTime
From DateTime
