Currently the output of sudo -l is not parseable out of the box, and contains 3 different sections:
- defaults for the host
- defaults for the user
- command that the user may run on the host

Example of sudo -l output is:
"""
Matching Defaults entries for root on localhost:
    env_reset, mail_badpass, secure_path=/usr/local/sbin\:/usr/local/bin\:/usr/sbin\:/usr/bin\:/sbin\:/bin, log_output, maxseq=150,
    iolog_dir=/var/log/sudo-io/%{user}, !requiretty

Runas and Command-specific defaults for root:
    Defaults!/usr/bin/sudoreplay !log_output

User root may run the following commands on localhost:
    (ALL : ALL) ALL
"""

It would be very useful to have the following flags as optional to "-l":
--host-defaults
--user-defaults
--commands

It should be also possible to combinate the options (ie: sudo -l --host-defaults --user-defaults)

Example of the expected output:

sudo -l --host-defaults
"""
Matching Defaults entries for root on localhost:
    env_reset, mail_badpass, secure_path=/usr/local/sbin\:/usr/local/bin\:/usr/sbin\:/usr/bin\:/sbin\:/bin, log_output, maxseq=150,
    iolog_dir=/var/log/sudo-io/%{user}, !requiretty
"""


sudo -l --user-defaults
"""
Runas and Command-specific defaults for root:
    Defaults!/usr/bin/sudoreplay !log_output
"""

sudo -l --commands
"""
User root may run the following commands on localhost:
    (ALL : ALL) ALL
"""

sudo -l --host-defaults --user-defaults
