hoh - print in the inserted order

perlthirst has asked for the wisdom of the Perl Monks concerning the following question:

I have hash of hash.

I will insert the data (key and value) in a hash whenever required.

At last while printing, it has to print the hash key and values, in the same order that i have inserted.

If any module is available to achieve this kindly advice.

Push the keys onto an array, and use it to drive the print loop. sas	[reply]

There is one caveat when using Tie::IxHash: although order is preserved when adding new key - value pairs, the keys must be unique. If you add a duplicate key, the value is changed, but the order of the original key is retained. This may or may not be what you want.

There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James	[reply]
