------------------------------------------

             Summary: Cloudmonkey should not forced coloured output when not interactive
                 Key: CLOUDSTACK-7670
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-7670
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Cloudmonkey
         Environment: # cloudmonkey --version
cloudmonkey 5.2.0

            Reporter: Shalom Bhooshi


Consider the output here from cloudmonkey here

{code}
cloudmonkey list zones 
404 Client Error: Not Found
{code}

One would expect to be able to pipe this output to another util to parse it
{code}
# cloudmonkey list zones | grep 'Client Error'; echo $?                                                                      
1
{code}

However, that does not match due to there being the non-printable ANSI codes to colour the output around the word ''Error''

{code}
# cloudmonkey list zones | cat -et
^[[34;01m404^[[39;49;00m^[[39;49;00m ^[[39;49;00m^[[39;49;00mClient^[[39;49;00m^[[39;49;00m ^[[39;49;00m^[[31;01mError^[[39;49;00m^[[39;49;00m:^[[39;49;00m^[[39;49;00m ^[[39;49;00m^[[39;49;00mNot^[[39;49;00m^[[39;49;00m ^[[39;49;00m^[[39;49;00mFound^[[39;49;00m$

# cloudmonkey list zones | grep 'Client.*Error'; echo $?                                                                     
404 Client Error: Not Found
0
{code}

Cloudmonkey ought to test if the output is interactive and only display in colour if it is through something like so

{code}
if sys.flags.interactive:
    #interactive, colours are ok
else:
    #not interactive, colours are not ok.
{code}
