I know almost all terminal emulators support displaying colors, and was wondering if the FRC netconsole also supported them. We’ve tried the standard VT100 escape sequences, and those didn’t work, but I know there are other terminal standards. Does anyone know anything about this?
Thanks in advance for your responses. I know it’s not very important, but I think it would be nice not to have to scroll through lines of text just to find what you’re looking for.
If netconsole does not support color fonts, I would like to make a feature request for next year. In particular, I would like to have support for the following ANSI escape sequences. It’s nice to be able to use different colors for messages such as information, warnings and errors. Since vxWorks as well as WPILib also spew tons of output to netconsole, if we could change color of our messages, it is a lot easier to spot them. It would be great if netconsole even allows filtering the messages by color (e.g. I don’t want to see messages in green color).
