make-c-array
====== make-c-array ====== This script prints binary data as an C array. This is useful for inserting binary blobs into source code. The script takes binary data in via stdin, and prints it out via stdout, so that it can work in a pipe. <code> #!/bin/bash FILE=$1 NAME=$2 echo "const unsigned char $NAME[] = {" od -v -w8 -tx1 $FILE | cut -c8- | \ sed \ -e"s/ / 0x/g" \ -e"s/ 0x/, 0x/g" \ -e"s/^, \(.*\)/ \1/" \ -e"$ d" | sed -e"$ !s/.*/&,/" echo "};" </code> ===Usage=== ==File Input== To print a file: <code> $ make-c-array in.bin Test > out.c </code> Where in.bin is the binary input file, Test is the name of the array, and out is the name of the C file to output to: <code c> const unsigned char Test[] = { 0xff, 0xd8, 0xff, 0xe0, 0x00, 0x10, 0x4a, 0x46, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x03, 0xff, 0xc4, 0x00, 0x14, 0x00, 0x00, 0xff, 0xda, 0x00, 0x08, 0x01, 0x01, 0x00, 0x00, 0x3f, 0x00, 0x37, 0xff, 0xd9 }; </code> ==Pipe Input== make-c-array can also take an input from stdin: <code> $ echo "Binary Test Data" | make-c-array - Hello > out.c </code> Result: <code c> const unsigned char Test[] = { 0x42, 0x69, 0x6e, 0x61, 0x72, 0x79, 0x20, 0x54, 0x65, 0x73, 0x74, 0x20, 0x44, 0x61, 0x74, 0x61, 0x0a }; </code>
