HexFile

Parses Intel HEX files and gives metadata about the file and records.

See http://en.wikipedia.org/wiki/Intel_HEX for information on the file format

Installation

Add this line to your application's Gemfile:

gem 'hex_file'

And then execute:

$ bundle

Or install it yourself as:

$ gem install hex_file

Usage

info = HexFile::Info.new(File.open('myfile.hex', 'r'))

info.format
# I8HEX

info.binary_size
# 12134

info.records.each do |record|
  puts record.data_size
  puts record.byte_count
  puts record.address
  puts record.type
  puts record.data
  puts record.checksum
  puts record.ok? # true if checksum correct
end

Also there is a bin script that gives a summary

$ hex_file_info myfile.hex
Format: I32HEX
Records: 7133
Binary Size (bytes): 113918

Note if you're an rbenv user, don't forget to rbenv rehash after installing the gem to make the hex_file_info script available.
