FWIW, when updating the amb egg I added helper macros/functions used by examples as exports from a new module, “amb-extras”, You may need to edit the color examples for generality but very much suggest the product is useful. > > -- > Erik Falor > Registered Linux User #445632 http://unnovative.net > _______________________________________________ > Chicken-users mailing list > Chicken-users@nongnu.org > https://lists.nongnu.org/mailman/listinfo/chicken-users _______________________________________________ Chicken-users mailing list Chicken-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/chicken-users
