# This is a simple example program to show how to use PyCdlib to open up an
# existing ISO passed on the command-line, and print out all of the file names
# at the root of the ISO.
# Import standard python modules.
import sys
# Import pycdlib itself.
import pycdlib
# Check that there are enough command-line arguments.
if len(sys.argv) != 2:
print('Usage: %s <iso>' % (sys.argv[0]))

# Create a new PyCdlib object.
iso = pycdlib.PyCdlib()
# Open up a file object. This causes PyCdlib to parse all of the metadata on the
# ISO, which is used for later manipulation.
iso.open(sys.argv[1])
# Now iterate through each of the files on the root of the ISO, printing out
# their names.
for child in iso.list_children(iso_path='/'):
print(child.file_identifier())
# Close the ISO object. After this call, the PyCdlib object has forgotten
# everything about the previous ISO, and can be re-used.
