Hash::Case::Preserve(3) User Contributed Perl Documentation Hash::Case::Preserve(3)

Hash::Case::Preserve - hash with enforced lower cased keys

   is a Hash::Case
   is a Tie::StdHash

 use Hash::Case::Preserve;
 tie my(%cphash), 'Hash::Case::Preserve';
 $cphash{StraNGeKeY} = 3;
 print keys %cphash;         # StraNGeKeY
 print $cphash{strangekey};  # 3
 print $cphash{STRANGEKEY};  # 3

Hash::Case::Preserve extends Hash::Case, which lets you play various trics with hash keys. This extension implements a fake hash which is case-insentive. The keys are administered in the casing as they were used: case-insensitive but case-preserving.

tie(HASH, 'Hash::Case::Preserve', [VALUES,] OPTIONS)
Define HASH to be case insensitive, but case preserving. The hash is initialized with the VALUES, specified as ref-array (passing a list of key-value pairs) or ref-hash.
OPTIONS is a list of key/value pairs, which specify how the hash must handle preservation. Current options:
  keep    'LAST'
keep => 'FIRST' | 'LAST'
Which casing is the preferred casing? The FIRST appearance or the LAST. Only stores will affect the casing, deletes will undo the definition. Defaults to LAST, which is slightly faster.

This module is part of Hash-Case distribution version 1.03, built on January 22, 2018. Website:
