Compatibility with Python 3.14 argparse.ArgumentParser color argument

[dieterd-sentea]

Since Python 3.14, argparse.ArgumentParser has a color argument (default True).

Unfortunately, this does not work well with autoprogram, with ANSI color escape sequences littered in the literal usage textbox, such as:

[1;34musage: [0m[1;35mmy-program

According to the documentation , a clean way out for autoprogram to fix this issue might be to set the NO_COLOR environment variable before loading the module during build.

EDIT: indeed, setting NO_COLOR=1 in the environment of sphinx-build fixes the issue for us, but unfortunately also removes all colors from sphinx build output.
