Embed resource files into your code via go generate command. This is a very simple solution to add the content of your files on the map[string][]byte. With a minimum of settings. Via bash script.

Quick start

  1. additional special comment in your code
...
//go:generate <path_to_bash_script> <file_name>
  1. run go generate ./
  2. should be created a new file in the same directory of the package (ending in _embeded.go)
