Re^3: Turning a hash into a line of links

I think at that point, it would be better to just maintain a real order, via a list, and associating values as part of an array ref.

my @sections = (
    [DMA  => 'dma'],
    [FST  => 'dma/fst'],
    [MRA  => 'dma/mra'],
    [BKS  => 'bks'],
    [MSU  => 'dma/msu'],
    [FMA  => 'dma/fma'],
    [FOMC => 'dma/FOMC'],
);

my @la = map
            { a( {-href => "/$_->[1]"}, "$_->[0] HOME" ) }
            @sections;
print join "\n|", @la;

In fact that's probably better than the key-mangling for this number of keys too.

The problem with that is you lose the ability to do look-ups so you have to iterate over the array to find the 'FMA' key/value pair. You could keep the hash but make it a HoH with the sort order held inside, like `my %sections = ( DMA = {attrib => q{dma}, sortOrder => 1}; ...` [download] but that strikes me as more complicated when most keys don't need it, just those with an odd ordering requirement.
