Singularity Message (Python) colors, Runtime

by vs 7 years ago

GNU/Linux ◆ xterm-256color ◆ bash 1302 views

This demonstrates the Singularity Python message bot’s usage of colors during runtime. You will notice that the progress bar, and info statements are not changed to be any different color. The default is to add color to the ERROR, ABORT, DEBUG, LOG, and WARNING prefixes (not the entire message). And colors can be completely disabled at any time with:

SINGULARITY_COLORIZE=false
export SINGULARITY_COLORIZE

For the complete gamut and an interactive example, see here
