ELF::Extract::Sections - Extract Raw Chunks of data from identifiable ELF Sections


version 1.001000


    use ELF::Extract::Sections;

    # Create an extractor object for
    my $extractor = ELF::Extract::Sections->new( file => '/path/to/' );

    # Scan file for section data, returns a hash
    my %sections  = ${ $extractor->sections };

    # Retreive the section object for the comment section
    my $data      = $sections{.comment};

    # Print the stringified explanation of the section
    print "$data";

    # Get the raw bytes out of the section.
    print $data->contents  # returns bytes



  my $object = ELF::Extract::Sections->new( file => FILENAME );

Creates A new Section Extractor object with the default scanner

  my $object = ELF::Extract::Sections->new( file => FILENAME , scanner => 'Objdump' )

Creates A new Section Extractor object with the specified scanner


  my $sections = $object->sorted_sections( field => SORT_BY )

Returns an ArrayRef sorted by the SORT_BY field, in the default order.

  my $sections = $object->sorted_sections( field => SORT_BY, descending => DESCENDING );

Returns an ArrayRef sorted by the SORT_BY field. May be Ascending or Descending depending on requirements.


Optional parameters. True for descending, False or absent for ascending.


A String of the field to sort by. Valid options at present are

1. Beta Software

This code is relatively new. It exists only as a best attempt at present until further notice. It has proved as practical for at least one application, and this is why the module exists. However, it can't be guaranteed it will work for whatever you want it to in all cases. Please report any bugs you find.

2. Feature Incomplete

This only presently has a very bare-bones functionality, which should however prove practical for most purposes. If you have any suggestions, please tell me via "report bugs". If you never seek, you'll never find.

3. Humans

This code is written by a human, and like all human code, it sucks. There will be bugs. Please report them.


This library uses Log::Log4perl. To see more verbose processing notices, do this:

    use Log::Log4perl qw( :easy );

For convenience to make sure you don't happen to miss this fact, we never initialize Log4perl ourselves, so it will spit the following message if you have not set it up:

    Log4perl: Seems like no initialization happened. Forgot to call init()?

To suppress this, just do

    use Log::Log4perl qw( :easy );

I request however you don't do that for modules intended to be consumed by others without good cause.
