NAME

File::IgnoreReadonly - Temporarily ensure a file is writable, even if it is readonly

SYNOPSIS

  SCOPE: {
      # Make writable, if possible (dies on error)
      my $guard = File::IgnoreReadonly->new( 'readonly.txt' );
      
      # Change the file
      open( FILE, '>readonly.txt' ) or die "open: $!";
      print FILE "New Content";
      close( FILE );
  }
  
  # File is now readonly again

DESCRIPTION

This is a convenience package for use in situations that require you to make modifications to files, even if those files are readonly.

Typical scenarios include tweaking files in software build systems, where some files will have been generated that are readonly, but you need to be able to make small tweaks to them anyways.

While it is certainly possible to simply set a file non-readonly (if it is readonly) and then set it back to readonly again afterwards, doing this in many places can get laborious and looks visually messy.

File::LexWrite allows for the creation of a simple guard object that will ensure a file is NOT set readonly (across multiple different operating systems).

When the object is DESTROY'ed at the end of the current scope, the file will be returned to the original file permissions it had when the guard object was created.

METHODS

new

The new method is a simple constructor that takes a single parameter.

It will set the file to writable if needed, and return a guard object.

When the guard object is DESTROYed, the file will be set back to the original file mode.

Returns a new File::IgnoreReadonly object, or throws an exception (dies) on error.
