# Use it when you want to symbolicate a crash log like this:
# 5   MyApp                   0x0044e89a 0x29000 + 4348058

def symbolicate(app_file, architecture, log_line)
	cmd_get_slide = "otool -arch #{architecture} -l #{app_file} | grep -B 3 -A 8 -m 2 \"__TEXT\""	
	result = %x[#{cmd_get_slide}]

	vmaddr_position = result.index("vmaddr")	
	slide = result[vmaddr_position + 7, 10].hex

	items = log_line.split(' ');
	load_address  = items[3]
	stack_address = items[2]
	
	symbol_address = slide.to_i + stack_address.hex - load_address.hex	
	cmd = "/Applications/Xcode.app/Contents/Developer/usr/bin/atos -arch #{architecture} -o #{app_file} #{symbol_address.to_s(16)}"
	
	symbolicate_result = %x[#{cmd}]
	puts "\nSymbolicated result:\n#{symbolicate_result}\n"
end

# Usage
app_file = "~/Downloads/build/MyApp.app/MyApp"
architecture = "armv7"
log_line = "11 MyApp 0x003c527b 0x56000 + 3601019"
