Bug#921080: lintian: warn about non-regenerated Parse::Yapp parsers

[Andrius Merkys <andrius.merkys@gmail.com>]

Package: lintian
Severity: wishlist

Hello,

packages sometimes ship pre-generated Parse::Yapp parsers while in principle they have to be generated from their source (this has already been discussed in debian-perl@ [1]). A simple check would be to look though the package source for Parse::Yapp-added headers. Example detection code in Perl:

if( $file_contents =~ /^#\s+This file was generated using Parse::Yapp version [\d.]+/ ) {
    warn "Parse::Yapp-generated parser";
}

I assume this could fall under the same 'source-is-missing' lintian tag.

Best,
Andrius
