SDL_Clown Script Interpreter
============================
The use of SDL_clown is exhaustively explained in the file "Manual",
however, here is a quick overview:
SDL_clown is a script interpreter experiment by young noob programmer.
It is written in C, has somewhat C-like syntax, and can do the
following:
- Arithmetic
- Assignment
- Built-in functions (sqrt/sin/cos/tan/floor)
- Control flow (if and while)
- Drawing colored rectangles
- Expressions
- Frame rate control
- Floating-point variables
- Floating-point variable arrays
- Floating-point variable input
- Interactive mode
- Mouse coordinates
- On-the-fly variable creation (without declaration)
- Output of text mixed with expression or variable values
- Parentheses
- Program arguments
- Relational operators
- Shebang
SDL_clown *cannot* do the following important things:
- Custom functions / procedures / subroutines
- Operator precedence (proper order of operations)
- String variables and operations
SDL_clown was not written by a programmer with great knowledge of
proper compiler design methods: I wrote much of it in complete
ignorance of stacks, grammars, etc.
In many parts of the source, rather than using existing
efficient algorithms and approaches (which I didn't know),
I tried to "reinvent the wheel" and improvised.
SDL_clown works by compiling scripts to bytecode and by running this
bytecode in a custom-made register-based VM.
