quickscript

What it is

quickscript is a easy way to "scriptify" a certain set of functions. This can be useful for configuration files or for writing command consoles in games or other applications that have a need for fast iteration times.

Todo

• Automatic Hotloading of source files
• Can only handle static or module level functions right now
• Improve error handling, it shouldn't crash when given faulty input
• Basic arithmetic
• Optimizations

How to use

You will need:

• dmd
• dub

Clone this repository and run "dub test" to see if it works as it should. Compile times can be a bit long because this project uses pegged as a dependency.

import quickscript.machine, std.stdio;


int square(int x){
  auto value = x*x;
  writeln("Squared: ", value);
  return value; 
}

//  Register the functions you wanna use in your script with a comma-separated argument list
registerFunctions!(square);


/*  
    Give the runtime a string containing your script.
    Basic syntax: FunctionIdentifier Arguments
    Functions are executed from left-to-right taking the previous output as input if available.
    After the execution a Variant is returned containing the value at the top of the stack
*/    
auto value = run("square 32 square");

//  To extract the value from this Variant
int myInt = value.get!int;

// Just to be sure
assert(myInt == square(square(32)));
