Voronovich:
I just had another amusing thought: Use a closure to hold your subroutine call with some of the arguments in place. It's a little more complicated, but if you've got multiple functions and/or sets of common arguments, I think it's a win::
$ cat closure_call.pl
#!/usr/bin/perl
use strict;
use warnings;
#
# Stuff you already have in your program
#
my ($handle, $not_today, $thingie)
= qw($handle $not_today $thingie);
sub printargs {
print "printargs(", join(", ", @_), ")\n";
}
# Get a reference to a function with some of the args already in place
my $simple = simplificate(\&printargs, $handle, $not_today, $thingie);
my $simpl2 = simplificate(\&printargs, "tittle", "tattle");
+
# Function to build a reference with some arguments already in place
sub simplificate {
my ($rFn, @args) = @_;
return sub { &$rFn(@args, @_) };
}
# Now call it as you need it
+
&$simple("Foo!", 234);
&$simple("Frob!",23);
&$simple("Forb!",54);
&$simple("ooF!",11);
&$simple("broF!", 'fakenum');
&$simple("Frap!",458);
&$simpl2("Whackmatic");
&$simpl2("Cybernicus");
&$simpl2("Canem Infernae");
$ perl closure_call.pl
printargs($handle, $not_today, $thingie, Foo!, 234)
printargs($handle, $not_today, $thingie, Frob!, 23)
printargs($handle, $not_today, $thingie, Forb!, 54)
printargs($handle, $not_today, $thingie, ooF!, 11)
printargs($handle, $not_today, $thingie, broF!, fakenum)
printargs($handle, $not_today, $thingie, Frap!, 458)
printargs(tittle, tattle, Whackmatic)
printargs(tittle, tattle, Cybernicus)
printargs(tittle, tattle, Canem Infernae)
Update: Darn! BrowserUk beat me to the punch!
Update: Forgot to update code for simpl2.
