something I have found vaguely useful that I just uploaded to CPAN for people to play with Mojo::Promise::Role::Repeat,
adds a *repeat()* method to the promise class/objects. The essential idea is that $promise->repeat(sub{...}) is equivalent to $promise->then(sub{...})->then(sub{...})->then(sub{...})->then(sub{...}) # .... forever except that repeat() also returns a "final" promise, which is - rejected, if any iteration dies with a value or returns a promise that gets rejected - resolved with @values, if any iteration calls $_->(@values) and if any run of the handler sub{...} returns normally or with a promise that gets resolved, those values get fed to the next run, $_ being bound, at the start of each run, to an escape function that doesn't return -- the moral equivalent of a break statement -- *but *you can also use this function to break out of nested loops/handlers as well (though you'll need to stash it in a lexical if you're going to do that). The pattern that seems to be coming up a lot for me is $ua->get_p($first_url)->repeat(sub { # ... parse page ... $_->() if (victory); # ... $ua->get_p($next_url); }) (I may eventually want to petition for some form of this to be added to Mojo::Promise, but one thing at a time...) -- You received this message because you are subscribed to the Google Groups "Mojolicious" group.
