IO::Notification::Recursive - Recursively watch a directory and any subdirectories


code

=begin code :lang<raku>

use IO::Notification::Recursive;

use IO::Notification::Recursive;

my $supply = watch-recursive(".");

# mention any changes on any files in the current directory and any subdirectories.
$supply.tap({ .say; });

# Also watch for changes in any newly created subdirectories
my $supply = watch-recursive(".", :update);

=end code


Raku comes with a way to watch a file or directory for changes called
C<IO::Notification.watch-path> (or C<IO::Path.watch>).  As files are
changed or created or removed from a directory you are watching, these
changes are registered on the C<Supply> created by C<.watch-path> (or
C<.watch>.


However, if any files are changed or created or removed from any
subdirectories, those do not generate changes on the Supply.  This
module provides a C<watch-recursive()> subroutine that will generate
changes for a directory and any subdirectories.


By default, if the directory you are watching has subdirectories created
while you are watching it, these new directories are B<not> added to the
list of watched directories.  If you pass the C<:update> parameter, newly
created subdirectories within any directories you are currently watching
will also be watched for changes.
