[PATCH] ver_linux: add comparison with required version and colour to output
Posted by Manuel Ebner an hour ago 
Add the required version from changes.rst.
Add code for comparison and print in colour (blue, green, red) depending
on the result of the comparison.

I had this patch on my mind for more than half a year. I was convinced I
couldn't do it because awk is such a special language. Took me less than
an hour without AI - WTF

Somehow I messed up the formating of the output. I guess it's this lines
+		ofmt = "%-20s\t%s\n"
but I couldn't figure it out :(

Honestly, I don't think this is going to go very far.

- You don't know that the output of the script is a terminal accepting
  ANSI escapes.

- You don't know if the user is running in light or dark mode

- Color blindness must be taken into account

If you really want to add this feature, you need to make it selectable
and configurable.  I honestly don't see that it would be worth it.

Thanks,

jon

None of the above reset the color (using "\033[37m", or the shorter
"\033[0m").
