Hexhelper

This gem simply makes it easy to dump a binary string as nicely formatted hex.

I found myself copying and pasting this code/project to a million different projects, so I thought it'd make sense to create a gem out of it.

Installation

Add this line to your application's Gemfile:

gem 'hexhelper'

And then execute:

$ bundle

Or install it yourself as:

$ gem install hexhelper

Usage

Using it is simple!

require 'hexhelper'

str = "This is a test string\x00\x01\x02"
puts HexHelper::to_s(str)

Which generates:

irb(main):001:0> require 'hexhelper'
=> true
irb(main):002:0> str = "This is a test string \x00\x01\x02"
=> "This is a test string \u0000\u0001\u0002"
irb(main):003:0> puts HexHelper::to_s(str)
00000000  54 68 69 73 20 69 73 20 61 20 74 65 73 74 20 73   This.is.a.test.s
00000010  74 72 69 6e 67 20 00 01 02                        tring....

It's also possible to indent with the indent parameter, and to highlight a particular offset with the offset parameter:

irb(main):004:0> puts HexHelper::to_s(str, indent: 4, offset: 0x10)
    00000000  54 68 69 73 20 69 73 20 61 20 74 65 73 74 20 73   This.is.a.test.s
    00000010 <74>72 69 6e 67 20 00 01 02                        tring....
