Feature Proposal:

Motivation

Description and Documentation

Following changes to lib/TWiki/attach.pm allows time/date processing:

Add after

use strict; 
use Assert; 


use TWiki::Time; 

and add before

    # I18N: Site specified %ATTACHEDIMAGEFORMAT% or %ATTACHEDFILELINKFORMAT%,
    # ensure that filename is URL encoded - first $name must be URL.
    $fileLink =~ s/\$name/$fileURL/;
    $fileLink =~ s/\$name/$attName/;


    my $fileext = $attName;
    $fileext =~ s/(.*\.)*([^.]*)/$2/;
    $fileLink =~ s/\$fileext/$fileext/;

    if (defined $att->{date})
    {
      my $date = $att->{date};
      use Time::localtime;
      my ($seconds,$minutes,$hours,$day,$mo,$ye,$wday,$ydat,$isdst) = gmtime($date);
      #require TWiki::time;
      $fileLink =~ s/\$date/TWiki::Time::formatTime( $date || 0)/gei;
      $fileLink =~ s/\$seconds/TWiki::Time::formatTime( $date || 0, "\$seconds")/gei;
      $fileLink =~ s/\$minutes/TWiki::Time::formatTime( $date || 0, "\$minutes")/gei;
      $fileLink =~ s/\$hours/TWiki::Time::formatTime( $date || 0, "\$hours")/gei;
      $fileLink =~ s/\$wday/TWiki::Time::formatTime( $date || 0, "\$wday")/gei;
      $fileLink =~ s/\$day/TWiki::Time::formatTime( $date || 0, "\$day")/gei;
      $fileLink =~ s/\$month/TWiki::Time::formatTime( $date || 0, "\$month")/gei;
      $fileLink =~ s/\$mo/TWiki::Time::formatTime( $date || 0, "\$mo")/gei;
      $fileLink =~ s/\$year/TWiki::Time::formatTime( $date || 0, "\$year")/gei;
      $fileLink =~ s/\$ye/TWiki::Time::formatTime( $date || 0, "\$ye")/gei;
    }

After this change, following attachment example is possible:
On TWIki Site:

   * Local ATTACHEDFILELINKFORMAT = |$year-$mo-$day|Effort        |[[%ATTACHURL%/$name][%ICON{$fileext}% $name]]| received from company xy |

Simple enhancement with nice effects, good enough to add to the next twiki version?

Discussion

sounds interesting - I guess what we need is documentation to go into the released topics, and unit tests.

This does look simple. It's gone nowhere on (tm)wiki. I'll commit to adding the feature and some tests for 1.2 if still interested. Should it also expand the common Formatting tokens? ( Foswiki::Func::decodeFormatTokens / Foswiki::expandStandardEscapes - $n, $nop, $quot, $comma, $percnt, $lt, $gt, $amp, $dollar) for consistency?
