 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. gPXE currently features a limited capability command language.

 +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.
 +
 +June 14: Implementation of arithmetic parser as decided.
