In IO::Spec::Cygwin§
See primary documentation in context for method join
method join(|c)
Same as IO::Spec::Win32.join
, except replaces backslashes with slashes in the final result.
In List§
See primary documentation in context for routine join
sub join(, *)method join(List: = "")
Treats the elements of the list as strings by calling .Str
on each of them, interleaves them with $separator
and concatenates everything into a single string.
Example:
say join ', ', <a b c>; # OUTPUT: «a, b, c»
The method form also allows you to omit the separator:
say <a b c>.join; # OUTPUT: «abc»
Note that the method form does not flatten sublists:
say (1, <a b c>).join('|'); # OUTPUT: «1|a b c»
The subroutine form behaves slurpily, flattening all arguments after the first into a single list:
say join '|', 1, <a b c>; # OUTPUT: «1|a|b|c»
In this case, the list <a b c>
is slurped and flattened, unlike what happens when join
is invoked as a method.
If one of the elements of the list happens to be a Junction
, then join
will also return a Junction
with concatenation done as much as possible:
say ("a"|"b","c","d").join; # OUTPUT: «any(acd,bcd)»
In Thread§
See primary documentation in context for method join
method join(Thread:)
Waits for the thread to finish.
In IO::Spec::Win32§
See primary documentation in context for method join
method join (Str , Str , Str --> Str)
Similar to catpath
, takes two path fragments and concatenates them, adding or removing a path separator, if necessary, except it will return just $file
if both $dir
and $file
are string '/'
or if $dir
is the string '.'
. The first argument is ignored (it exists to maintain consistent interface with other IO::Spec
types for systems that have volumes).
IO::Spec::Win32.join('C:', '/some/dir', 'foo.txt').say;# OUTPUT: «C:/some/dir\and/more»IO::Spec::Win32.join('C:', '.', 'foo.txt').say;# OUTPUT: «C:foo.txt»IO::Spec::Win32.join('C:', 「\」, '/').say;# OUTPUT: «C:\»IO::Spec::Win32.join('//server/share', 「\」, '/').say;# OUTPUT: «//server/share»IO::Spec::Win32.join('E:', '', 'foo.txt').say;# OUTPUT: «E:foo.txt»
In IO::Spec::Unix§
See primary documentation in context for method join
method join ($, Str , Str --> Str)
Similar to catpath
, takes two path fragments and concatenates them, adding or removing a path separator, if necessary, except it will return just $file
if both $dir
and $file
are string '/'
or if $dir
is the string '.'
. The first argument is ignored (it exists to maintain consistent interface with other IO::Spec
types for systems that have volumes).
IO::Spec::Unix.join($, 'foo', 'bar').say; # OUTPUT: «foo/bar»IO::Spec::Unix.join($, '/', '/').say; # OUTPUT: «/»IO::Spec::Unix.join($, '.', 'foo').say; # OUTPUT: «foo»say .join(True,".","/foo"); # OUTPUT: «/foo»
In Any§
See primary documentation in context for method join
method join( = '') is nodal
Converts the object to a list by calling self.list
, and calls .join
on the list. Can take a separator, which is an empty string by default.
(1..3).join.say; # OUTPUT: «123»<a b c>.join("❧").put; # OUTPUT: «a❧b❧c»
