Overview

Hex

Picture of Hex being used

A project to create alternate (and more user friendly) versions of existing hex tools.

The project can be installed as a extension to the github-cli.

Installation

To install as a standalone binary, run the following commands:

git clone https://github.com/sohomdatta1/hex.git
cd hex
./script/normal-build.sh

For use with github-cli, run the following commands:

git clone https://github.com/sohomdatta1/hex.git
cd hex
./script/build.sh
gh extension install .

Operations

Currently, the following operations are supported:

  • str - Dumps out readable strings in a particular file
  • dump - Dumps out a particular file in hexdump format

If a pager is not desired, the NOPAGER env variable can be set. If colored output is not desired, the NOCOLOR env variable can be set.

Language

The project is written in Rust, mainly as a way for me to learn the language. I feel like implementing common tools such as these will be a nice way to get familiar with the basics.

    hexyl appears to be marginally faster while computing the hexdump. Investigate why this is the case, and make performance improvements (especially will be benificial for larger files)

    Investigate the idea of adding profiles

    Profiles (being able to color code bytes of a particular format depending on some kind of grouping) -- so like for the binary dump of a http request, the header would be a different color from the body and so on.

  • Add diff

    Add diff

    Diffing for binary files is a bit scattered here and there with the current best solution being hexdump file1 > file1.bin && hexdump file2 > file2.bin && diff file1.bin file2.bin which is inconvinient and sometimes misleading. We should provide that under this tool.

  • Add grep

    Add grep

    Currently my workflow for grepping/searching for a sequence of bytes is effectively to run the following command hexdump filename | grep 'ca fe'. I feel like a better CLI interface for this is necessary.
