Progress!

I finally got the 'else' statement finished and working, so now entire decision structures are working including scopes.  I also implemented built-in functions.  They are fully functioning with return values (or no return value) and multiple arguments.  However, I have not yet tested overloading and there is no user defined function option yet.  Lastly, I implemented while loops.  They are probably the simplest loop structure to implement but it provided a nice a framework for do...while and for loops.  After I implement those last two loops I will implement some engine specific things such as states and events.  After that it will be a fully functioning scripting engine!

Nothing to Report

I didn't work on anything this week so... yeah.  I will hopefully have 'else' statements done and hopefully the beginning of functions by this Sunday though.

Busy Week

I managed to get the start of the 'else' statement done, but other than not much was accomplished.  I fixed a few bugs and did a little optimization, but after Tuesday I got really busy.  Maybe this week will be better.

A Bunch of Progress!

I got a lot done this week!  I have a working intermediate code generator and virtual machine, basically the code can be compiled and ran.  I still have more to implement, specifically functions, but so far I have variables (numbers or strings as data types), assignment statements, and decision structures.  The 'else' statement isn't implemented yet, but I have the framework for code generation done so the rest will be easier.  Here is some example of code that would compile correctly:

num a = 100;
num b = 20;
a = a + 5 * b;
if ( a == 200 )
{
      b = 50;
}

The result would be, a = 200 and b = 50.  I also implemented complex conditional statements such as:

if ( a == 50 & b == 20 | ((c == 56 & d == 23) | e == 10) )

By next week I hope to have full decision structures done and some simple functions working (no return type or parameters)
