class CompressedGenerator(SimpleGenerator)
      Adds Zlib compression and decompression to generator
 
   Methods defined here:
getData(self, source, package=None)
Get the data to be encoded in the package
getDataRepr(self, source, destination, package=None)
data as Python code assigning a value to variable "data"
getHeader(self, source, destination, package=None)
Get the header, written before the data variable
Data and non-method functions defined here:
__doc__ = 'Adds Zlib compression and decompression to generator'
__module__ = 'resourcepackage.defaultgenerators'
Methods inherited from SimpleGenerator:
__call__(self, source, destination, package=None)
Encode source in destination for package
__repr__(self)
getFooter(self, source, destination, package=None)
Get the footer, written after the data variable

Functions
            
crunch_data(source, chunkSize=60, charMap={'\x00': r'\000', '\x01': r'\001', '\x02': r'\002', '\x03': r'\003', '\x04': r'\004', '\x05': r'\005', '\x06': r'\006', '\x07': r'\007', '\x08': r'\010', '\t': r'\011', ...})
Try to get a minimal representation of a binary as Python code
 
This is a re-implementation that tries to
minimise the size of the data by embedding extended
characters in the source code.
