'''

Converts a binary file into JSON.

This lets you transform a binary file into something you can

easily bundle inside a web page.

Usage: file2json.py FILENAME VARNAME

FILENAME - the binary file

VARNAME - the variable to store it in (the output will be VARNAME = [...])

'''

import os, sys

data = open(sys.argv[1], 'r').read()

sdata = map(lambda x: str(ord(x)) + ',', data)

sdata[-1] = sdata[-1].replace(',', '')

lined = []

while len(sdata) > 0:

lined += sdata[:30]

sdata = sdata[30:]

if len(sdata) > 0:

lined += ['\n']

json = '[' + ''.join(lined) + ']'

if len(sys.argv) < 3:

print json

else:

print 'var ' + sys.argv[2] + '=' + json + ';'
