Bug#840099: libparse-debianchangelog-perl: Don't trim file name in error messages

[Christoph Biedl]

Package: libparse-debianchangelog-perl
Version: 1.2.0-10
Severity: wishlist

Dear Maintainer,

at the moment, Parse::DebianChangelog left-trims the file name in
error messages. This caused some trouble when processing a major set
of packages where one had a zero-size debian/changelog.

As a demonstation:

=====================================================================
#!/usr/bin/perl

use 5.010;
use strict;
use warnings;

use File::Temp qw(tempfile);
use Parse::DebianChangelog;

my ($fh, $temp_file) = tempfile (
    "Parse::DebianChangelog.$$.XXXXX",
    'TMPDIR' => 1,
    'UNLINK' => 1,
);

print "Changelog file is $temp_file\n";
my $chglog = Parse::DebianChangelog->init();
$chglog->parse( { infile => $temp_file } );
=====================================================================

| Changelog file is /tmp/Parse::DebianChangelog.607990.0zl6f
| WARN: /tmp/Parse::DebianCh(l0): found eof where expected first heading

Identifying the culprit took more time for me than it should,
especially since the actual trimming wasn't marked as such, i.e. even
"/tmp/Parse::DebianCh(...)(l0)" would have been of help. The current
output however left me somewhat lost.

Suggestions:

- Don't trim at all
- Trim the file name on the left side, and to at least 30 characters.
  Rationale: A path name as in "project-name/debian/changelog" should
  still be fully visible.

And if you trim the name, mark it accordingly.

Regards,

    Christoph
