binario

Simple work with binary data in Python.

What is the binario?

binario is the Python package that lets an application read/write primitive data types from an underlying input/output stream as binary data.

And which primitive data types it can process?

It can work with booleans, integers, shorts, long integers, floats, doubles, strings and any byte buffers.

How to write data?

It's simple. Just create instance of Writer and then do your work:

>>> import binario
>>> w = binario.Writer("file.dat")
>>> w.write_short(2014)
>>> w.write_bool(True)
>>> w.write_float(3.1415)
>>> w.write_string("Hello, world!")
>>> w.write(bytes([128, 20, 10, 255, 0]))

And how to read data?

It's simple too. Like outputting, create Reader and then do your work:

>>> import binario
>>> r = binario.Reader("file.dat")
>>> r.read_short()
2014
>>> r.read_bool()
True
>>> r.read_float()
3.1415
>>> r.read_string()
"Hello, world!"
>>> r.read(5)
b'\x80\x14\n\xff\x00'

Which byte order specified by default?

By default it is network order (or big-endian).

Okay, it is good, but if I want to change byte order for Reader or Writer?

Not a problem! Just specify it:

>>> import binario
>>> r = binario.Reader("file.dat", binario.LITTLE_ENDIAN)
>>> w = binario.Writer("another_file.dat", binario.BIG_ENDIAN)

What about append new data to existing file?

Yeah, it is also very simple:

>>> import binario
>>> w = binario.Writer("incomplete_file.dat", append=True)

How to install(upgrade) this package?

Just type in your terminal:

$ pip install binario
$ pip install binario --upgrade
