Designing a scripting lanaguage

Ironica · 2003-06-16T09:20:38

Hey guys, hehe.I wanna design a very basic scripting language (in C++) for a game. Now I started reading lines from a file, then used strstr to seperate arguements etc. I''m just kinda having problems implementing if... else, and stuff. I did get off to a pretty good start, could call a function with arguements and so far worked well. But then I got kinda confused over writing an if statement. I wanna keep it simple, so I''d want it look something like: @if boolean_function_1 5 7 // 5 and 7 being the arguements boolean_function_2 @then void_function_1 @else void_function_2 @endif Anyone point me in the right direction? To be honest, I''m pretty clueless, and am not even sure if reading the file line by line is a good way to do it. Since my if statement is on multiple lines, I''m not really sure how to go about doing this.

Trust me, after going through all of my college compiler and interpreter courses, break and continue arent all that simple

I designed a complete script language with its interpreter last winter. I highly suggest to you the book "Modern Compiler Design", dont get scared by the name, plenty of good things on interpreters. Read the section on top-down recursive parsers, its probably the most basic form of interpreter.
