context::preserve
Context::Preserve(3pm) User Contributed Perl Documentation Context::Preserve(3pm)NAME
Context::Preserve - run code after a subroutine call, preserving the context the subroutine would have seen if it were the last statement
in the caller
SYNOPSIS
Have you ever written this?
my ($result, @result);
# run a sub in the correct context
if(!defined wantarray){
some::code();
}
elsif(wantarray){
@result = some::code();
}
else {
$result = some::code();
}
# do something after some::code
$_ += 42 for (@result, $result);
# finally return the correct value
if(!defined wantarray){
return;
}
elsif(wantarray){
return @result;
}
else {
return $result;
}
Now you can just write this instead:
use Context::Preserve;
return preserve_context { some::code() }
after => sub { $_ += 42 for @_ };
DESCRIPTION
Sometimes you need to call a function, get the results, act on the results, then return the result of the function. This is painful
because of contexts; the original function can behave different if it's called in void, scalar, or list context. You can ignore the
various cases and just pick one, but that's fragile. To do things right, you need to see which case you're being called in, and then call
the function in that context. This results in 3 code paths, which is a pain to type in (and maintain).
This module automates the process. You provide a coderef that is the "original function", and another coderef to run after the original
runs. You can modify the return value (aliased to @_) here, and do whatever else you need to do. "wantarray" is correct inside both
coderefs; in "after", though, the return value is ignored and the value "wantarray" returns is related to the context that the original
function was called in.
EXPORT
"preserve_context"
FUNCTIONS
preserve_context { original } [after|replace] => sub { after }
Invokes "original" in the same context as "preserve_context" was called in, save the results, runs "after" in the same context, then
returns the result of "original" (or "after" if "replace" is used).
If the second argument is "after", then you can modify @_ to affect the return value. "after"'s return value is ignored.
If the second argument is "replace", then modifying @_ doesn't do anything. The return value of "after" is returned from
"preserve_context" instead.
Run "preserve_context" like this:
sub whatever {
...
return preserve_context { orginal_function() }
after => sub { modify @_ };
}
or
sub whatever {
...
return preserve_context { orginal_function() }
replace => sub { return @new_return };
}
Note that there's no comma between the first block and the "after =>" part. This is how perl parses functions with the "(&@)" prototype.
The alternative is to say:
preserve_context(sub { original }, after => sub { after });
You can pick the one you like, but I think the first version is much prettier.
