Log:
BIG CHANGES (this commit is 3000 lines longer than the code is :) )
This code has been tested and I believe it produces identical results to
the lonspreadsheet.pm in 0.6.1.
The spreadsheet is now an object, accessed via methods and all that nifty
stuff.
&mask, being a pure function, now memoizes its results.
The HASH and related subroutines have temporarily been removed from the
safe space. I would like to remove them permenantly but this is unlikely
to be feasable.
&expandnamed and &sett have been moved outside the safe space.
logging and accessor/setter functions have been added. In
more than a few cases the previous code did
foreach my $cell (keys(%formulas)) {
next if ($cell !~ /^A(\d+)/);
..
methods have been written to return just the needed cells for the 'A' column
and the template row.
A few debugging routines have been added ($sheet->dump_formulas_to_log() and
$sheet->dump_values_to_log() );
The code has been re-arranged and will be re-arranged further.
