A simple utility to encode a file (or any other data) into a Go byte slice.
Having set up your Go environment, simply run
go get github.com/cratonica/2goarray
Then use by piping a file into the utility and capturing the output. You must provide a name for the generated slice symbol and package name. For example:
$GOPATH/bin/2goarray MyArray mypackage < myimage.png > myimage.go
This will output something like:
package mypackage
var MyArray []byte = []byte {
0x49, 0x20, 0x63, 0x61, 0x6e, 0x27, 0x74, 0x20, 0x62, 0x65, 0x6c, 0x69,
0x65, 0x76, 0x65, 0x20, 0x79, 0x6f, 0x75, 0x20, 0x61, 0x63, 0x74, 0x75,
0x61, 0x6c, 0x6c, 0x79, 0x20, 0x64, 0x65, 0x63, 0x6f, 0x64, 0x65, 0x64,
0x20, 0x74, 0x68, 0x69, 0x73, 0x2e, 0x20, 0x4b, 0x75, 0x64, 0x6f, 0x73,
0x20, 0x66, 0x6f, 0x72, 0x20, 0x62, 0x65, 0x69, 0x6e, 0x67, 0x20, 0x74,
0x68, 0x6f, 0x72, 0x6f, 0x75, 0x67, 0x68, 0x2e, 0x0a,
