Chef

Chef is a stack-based language where programs look like cooking recipes. Chef was designed by David Morgan-Mar in 2002.

Design principles

According to the Chef Home Page, the design principles for Chef are:

• Program recipes should not only generate valid output, but be easy to prepare and delicious.
• Recipes may appeal to cooks with different budgets.
• Recipes will be metric, but may use traditional cooking measures such as cups and tablespoons.

Hello, world! in Chef

David Morgan-Mar wrote the example program Hello World Souffle; it does generate valid output, however falls short of the design goals of being "easy to prepare and delicious". Later, Mike Worth wrote a hello world program that can be followed as a functional (if slightly odd) recipe for a chocolate cake:

Hello World Cake with Chocolate sauce.

This prints hello world, while being tastier than Hello World Souffle. The main
chef makes a " world!" cake, which he puts in the baking dish. When he gets the
sous chef to make the "Hello" chocolate sauce, it gets put into the baking dish
and then the whole thing is printed when he refrigerates the sauce. When
actually cooking, I'm interpreting the chocolate sauce baking dish to be
separate from the cake one and Liquify to mean either melt or blend depending on
context.
