     [ https://issues.apache.org/jira/browse/CASSANDRA-4634?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Tyler Hobbs updated CASSANDRA-4634:
-----------------------------------

    Attachment: 4634-color-option.txt

Attached patch changes the color option to accept a choice of {{always}}, {{never}}, or {{auto}}, defaulting to {{auto}}, which uses colors if not reading from a file and stdout is connected to a terminal (at least as well as we can detect that).  I based the options off of {{ls}} and {{grep}}, which use the same format.

> There's no way to disable colors with cqlsh, despite it having a {{--color}} option, because that option can only enable color if present, not disable it, and the default is that color is enabled.
> (Incidentally, if the {{--file}} option is used, it will disable color.)
