NAME
PerlX::AsyncAwait - async/await keywords in pure perl
EXPERIMENTAL
This is batshit crazy, even for mst. No warranty, express or implied.
SYNOPSIS
First recommendation:
use Future::AsyncAwait; # instead
because it's XS and does suspend/resume properly and will perform
better.
This module, on the other hand, is an attempt to make it all work in
pure perl, by rewriting your code into a .pmc file that contains extra
code to handle suspend/resume at the pure perl level. Which is great if
you want fatpacking or support for older perls, but not the best
solution otherwise.
That said:
use PerlX::Generator::Runtime;
use PerlX::Generator::Compiler;
my $f = async_do {
...
await some_future_returning_function();
...
return ...;
};
my $result = $loop->await($f);
my $sub = async_sub {
...
await some_future_returning_function($_[0]);
...
return ...;
};
my $result = $loop->await($sub->(...));
This will result in a .pmc file that depends only on
PerlX::AsyncAwait::Runtime. See the examples/ directory for what the
results end up looking like. Note that the order is important, you
*must* use the runtime *before* the compiler or weirdness will ensue.
Note that since the .pmc does not require the compiler, on the author
side you will need to depend on Module::Compile directly.
DESCRIPTION
There should be details here but I'm shipping this now so the YAPC::EU
crowd can play with it.
LIMITATIONS
We rewrite "foreach" into a 3-arg "for" so you *can* await inside a
foreach loop.
We do not handle 'local' in any way shape or form that. I'll add that
later.
