Byte Blade

A binary data analyzer with numpy array like syntax.

Have a data file and you don't want to open a python shell and use numpy? Not to worry, byte_blade is here!

Installing the latest release

$ wget https://github.com/lincketheo/byte_blade/releases/download/v0.0.1/bb-v0.0.1-linux-x86_64.tar.gz
$ tar xvf bb-v0.0.1-linux-x86_64.tar.gz

Building:

$ make clean
$ make
$ ./bb --help

Usage:

By default byte blade assumes uint8_t data in dec mode. So if you just run:

$ ./bb <filename>

It will print out all the bytes of the file.

You can specify the data type with various flags. For example, let's suppose your data is a string of complex floats, then run

$ ./bb <filename> CF64

You can see a list of all supported data types by running ./bb --help

If you want to see your data in hex format, you can run with the --hex flag (there's --hex, --bin and --dec):

$ ./bb <filename> --hex CF64

You can also specify the endianess of your output. By default, it's your system's endianess:

$ ./bb <filename> --hex --big CF64

Too much data? Not to worry, byte_blade supports indexing. You can add numpy-like indexing (with negative numbers included). Here are some examples:

Prints element 5

$ ./bb <filename> --hex --big CF64 5

Prints elements 5->size-10

$ ./bb <filename> --hex --big CF64 5:-10

Prints elements 5->end

$ ./bb <filename> --hex --big CF64 5:

Prints elements 0->size-1

$ ./bb <filename> --hex --big CF64 :-1

Prints elements 0->10

$ ./bb <filename> --hex --big CF64 :10

Prints elements size-5->10

$ ./bb <filename> --hex --big CF64 -5:10

Prints all elements

$ ./bb <filename> --hex --big CF64 :

Also Prints all elements

$ ./bb <filename> --hex --big CF64
