====== Lynus Vaz: Enhanced scripting language ====== ===== Project Plan ===== gPXE currently features a limited capability command language. A more powerful scripting language would be useful to users: they can specify boot policies or other customizations as a script, without having to understand gPXE completely, or having to edit the code. Features: Evaluating arithmetic/boolean expressions If-then-else branches Quoting ==== Summary ==== ==== Outline ==== * These changes need an arithmetic evaluator, to accept expressions. * Define if, then, else commands. I am thinking of something like: if [ expr ] statements else statements fi I think this would be the simplest to deal with. * Define a goto command, or alternatively for, and while commands * A simple syntax to handle expression expansion: something like the current ${} for variables. * Also, handling variables in these expressions, especially string variables * I also think we need to have some operators like: check if interface exists (maybe (--i net1)?) ==== Milestones and Timeline ====
