gpack 0.2.1

GPack is struct analog!

An analogue of Struct for python and even better!!

Installing:

pip install gpack

Example usage:

import gpack 
gpack.setup()
"1234".pack("bi",2)

GPack replaces the python compiler for improved and convenient operation.

b - Big-Endian

l - Little-Endian

i - Int

I - Signed Int

s - String

o - Bool

n - Bytes

> - Big-endian

< - Little-endian

More usage:

test_data = [123, -123, "aboba", b"aboba", 1234, True, False, 321]
import gpack
gpack.setup()
packed = test_data.pack("bilIsniooi", 1, 1, 5, 10, 5, 1, 1, 2)

unpacked = packed.unpack("bi lI s n i o o i", 1, 1, 5, 10, 5, 1, 1, 2)
print(unpacked)

[123, -123, 'aboba', b'aboba\x00\x00\x00\x00\x00', 1234, True, False, 321]

You can use the spaces for ease of use

Format Specifiers with sizes

Numbers after formats specify sizes in bytes:

# Pack string (5 bytes) + int (4 bytes) + bool (1 byte)
packed = ["hello", 123, True].pack("s i o", 5, 4, 1)

# Unpack with same sizes
unpacked = packed.unpack("s i o", 5, 4, 1)

Also you can use without setup:

import gpack
gpack.pack([123],'i',1)
gpack.unpack(b'}','i',1)

You can use size inside arg 1:

import gpack
gpack.setup()
[123].pack("1i") # Pack 123 with unsinged int and size 1
[123].pack("i",1) # Pack 123 with unsinged int and size 1

To use from libs remove "gpack.setup()"
