Maintainer(s)' notes

If you are reporting a bug in Spreadsheet::ParseExcel here are some pointers

1) State the issues as clearly and as concisely as possible. A simple program or Excel test file (see below) will often explain the issue better than a lot of text.

2) Provide information on your system, version of perl and module versions. The following program will generate everything that is required. Put this information in your bug report.

    #!/usr/bin/perl -w

    print "\n    Perl version   : $]";
    print "\n    OS name        : $^O";
    print "\n    Module versions: (not all are required)\n";

    my @modules = qw(
                      Spreadsheet::ParseExcel
                      Scalar::Util
                      Unicode::Map
                      Spreadsheet::WriteExcel
                      Parse::RecDescent
                      File::Temp
                      OLE::Storage_Lite
                      IO::Stringy
                    );

    for my $module (@modules) {
        my $version;
        eval "require $module";

        if (not $@) {
            $version = $module->VERSION;
            $version = '(unknown)' if not defined $version;
        }
        else {
            $version = '(not installed)';
        }

        printf "%21s%-24s\t%s\n", "", $module, $version;
    }

    __END__

3) Upgrade to the latest version of Spreadsheet::ParseExcel (or at least test on a system with an upgraded version). The issue you are reporting may already have been fixed.

4) Create a small example program that demonstrates your problem. The program should be as small as possible. A few lines of codes are worth tens of lines of text when trying to describe a bug.

5) Supply an Excel file that demonstrates the problem. This is very important. If the file is big, or contains confidential information, try to reduce it down to the smallest Excel file that represents the issue. If you don't wish to post a file here then send it to me directly: jmcnamara@cpan.org

6) Say if the test file was created by Excel, OpenOffice, Gnumeric or something else. Say which version of that application you used.

7) If you are submitting a patch you should check with the maintainer whether the issue has already been patched or if a fix is in the works. Patches should be accompanied by test cases.

Subject: Undesirable use of $& variable within Spreadsheet::ParseExcel
Download (untitled) / with headers
text/plain 456b
Spreadsheet/ParseExcel/Utility.pm internally uses the $& (aka $MATCH) variable, which introduces a known performance hit to all regular expression matches in any application that has loaded Spreadsheet::ParseExcel. This applies even to regular expressions outside of the Spreadsheet::ParseExcel libraries. Attached is a proposed patch to Utility.pm that eliminates the use of $&. Regretably, there are no regression tests for the modified lines of code.

Ouch. Thanks for that. I've only just begun to work my way through the cruft. Show quoted text

Not to worry. The existing Utility.pm code wouldn't pass a regression test either. John. --
Hi, Fixed in version 0.46. Thanks, John. --
