Hi,
I would like to propose adding the "last" statement
to the "grep", which currently doesn't work:
maas34: perl -e 'grep { print and $_ == 3 and last } (1,2,3,4,5)'
123
Can't "last" outside a loop block at -e line 1.
This way it would be possible to use such constructs:
print_header ($query);
if ($but and not check_pass ($pass))
{
print abstract (q{<SPAN CLASS="pink">Wrong password</SPAN> ...
}
elsif ($but eq 'Create' and $proj and $sub and $pack and $prel)
{
insert_update_pack ($dbh, $proj, $sub, $pack, $prel);
}
elsif (grep { /^Delete\s+([\w.-]+)\|([\w.-]+)\|([\w.-]+)\|([\w.-]+)$/ and
$query -> param ($_) eq 'Delete' and last } $query -> param)
{
delete_pack ($dbh, $1, $2, $3, $4);
}
else
{
print abstract (q{Please specify a project and ...
}
Here I am looking for a button with a special name - "Delete ..." -
and there can be only one such button, so I have to interrupt the
"grep" after I find it (otherwise the $1, $2, $3, $4 might be unset).
I have to do it this strange way (using NAME and not the VALUE of
an HTML submit-button), because the VALUE is shown as the label of
the button (and I want it to show just "Delete", not "Delete CAPC|blah...")
Regards
Alex
