use_color()

bool celeritas::use_color

(

)

Whether colors are enabled by the environment.

The NO_COLOR environment variable, if set to a non-empty value, disables color output. If either of the CELER_COLOR or GTEST_COLOR variables is set, that value will be used. Failing that, the default is true if stderr is a tty. The result of this value is used by ansi_color .
