OK, the problem is now fixed. So either you recompile from the github repo, or you wait for the next release.

I am using the Gambit-C Interpreter on Windows 7.

The terminal window comes up with grey text on a black background. When I change the colours in the window title bar options they revert back to the white on black for all entered text and responses. This is different from the behaviour of the standard windows terminal.

I cannot see any options to change this behaviour so any help will be appreciated. The current choices do not project well even with large fonts and bold text.

thanks

There’s a function to change the attributes of the console's input text (entered by the user) and the output text:

(tty-text-attributes-set! (repl-output-port) #x088 #x088)

Where the two numbers encode the color of the input and output respecively. Here’s the encoding:

   (define style-normal    0)
   (define style-bold      1)
   (define style-underline 2)
   (define style-reverse   4)

   (define color-black   0)
   (define color-red     1)
   (define color-green   2)
   (define color-yellow  3)
   (define color-blue    4)
   (define color-magenta 5)
   (define color-cyan    6)
   (define color-white   7)
   (define default-color 8)

   (define (make-text-attr style fg bg)
     (+ (* style 256) fg (* bg 16)))

Unfortunately I think this functionality is broken on Windows. I’ll push a fix soon.
