| - | 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. | ||

| + | Current work: I currently have code to evaluate arithmetic expressions, involving integers only (variable substitution is done before it is called). The usual C operators are supported (no variables, so no assignment), with their usual precedence and associativity. | ||
| + | |||
| + | June 8: Finalize syntax issues: dealing with string variables, use ${} for arithmetic expressions as well or define another delimiter, syntax for if, and loops. | ||
