ENH: `--no-color` CLI argument option to remove color for better automation/pipeline output

[davidjeddy]

What would you like to be added: --no-color CLI argument option

Why is this needed: Automation/Pipeline/Terminals with no color support display garbage string \033[0m

Additional context:

[noqcks]

Is this just the install script displaying the garbage color strings? Or does it happen with usage of xeol cli as well?

we do check if the terminal supports colors in the install script here, but it seems like it's failing in this case.

can you tell me what these two commands return in your shell

• tput colors
• echo $TERM

Looks to be the installer is printing the color characters.

bash-5.2$ tput colors
256
bash-5.2$ echo $TERM
xterm-256color
