rbt now supports colorized logging when writing to a TTY (otherwise,
uncolored logging will be used). The colors can be specified in
.reviewboardrc in the COLORS variable, which maps logging levels
to colors (as plain text names) or None. An invalid color name will
be mapped to no color.

As part of this, the config parsing for nested (dict) variables has
been updated to be more generic and provide defaults where
appropriate.

  • Ran rbt to pipe and to a file: colored logging was not observed.
  • Ran rbt to a terminal: logging was colored appropriately.
