lib:SelectSaver

See the current Perl documentation for lib:SelectSaver.

Here is our local, out-dated (pre-5.6) version:


SelectSaver - save and restore selected file handle



    use SelectSaver;

    {
       my $saver = new SelectSaver(FILEHANDLE);
       # FILEHANDLE is selected
    }
    # previous handle is selected

    {
       my $saver = new SelectSaver;
       # new handle may
    

A SelectSaver object contains a reference to the file handle that was selected when it was created. If its new method gets an extra parameter, then that parameter is selected; otherwise, the selected file handle remains unchanged.

When a SelectSaver is destroyed, it re-selects the file handle that was selected when it was created.

[james28909]: yep, i am scraping a websites date/time stamp from an article. none of that is relevant though because the strings i get are as expected. the returned data from the website is the list of @weekdays
[james28909]: i need to convert those @weekdays to an numerical date based off of scalar localtime
[james28909]: i have thught about this and though about it lol
[james28909]: also remember, that if 'Today' is may 1, then Yesterday is not may 31 lol
[james28909]: theoretically speaking ofcourse
