Rflatten.pm
Today I wrote a module that I like to use eventually for sending complex data structures with a simple html POST form. Because POST is only Key/Value a flat hash seems to be the way to go. The module now converts:
$VAR1 = [ 'ccc', 'ddd' ];
into this hash:
$VAR1 = {
':0' => 'ccc',
':1' => 'ddd'
};
The module knows “:” is an Array element. “.” is used as a hash key. This complex structure:
$VAR1 = {
'qqqqqq' => [
'ccc',
{
'vvvvv' => 'ddd'
}
]
};
It will convert to:
$VAR1 = {
'.qqqqqq:0' => 'ccc',
'.qqqqqq:1.vvvvv' => 'ddd'
};
The key “qqqqqq” is written in the second key as well. This enables me to create any structure. OK this works but how do you specify a simple Scalar value? I choose this:
$VAR1 = \'cccc';
converts to:
$VAR1 = {
'SCALAR' => 'cccc'
};
‘SCALAR’ can be any word as long as it does not contain “:” or “.”. I hope to get a http POST example online soon for you all to see and checkout.
