WAL

WAL (WinAPILanguage) is a scripting DSL that compiles to C++. It is intended for executing specific actions on given time.

State

Usability: ❌ in development/very unstable.

Currently working code (as of 10.12.2022):

fn get_string() {
    return "Hello, world!";  
}
print(get_string());

TODO

• Imports (partially)
• Functions
• Variables (partially)
• Timed blocks
• Binary and unary expressions
• Conditions (if, while, for)
• STD
• • WinAPI shenanigans (message boxes, window search, ...)
• • SFML(?)
• • Utility (strings, arrays, ...)

Code example (currently does not compile)

import 'windows';
@defaultUnit(ms)

const WELCOME_STRING = "hello, ";
const MESSAGE_BOX_STRING = "hi!";

fn print_hi() {
	subject = "world!";
	print(WELCOME_STRING + subject);
}

init: {
	print_hi(); // hello, world!
}

1000: message_box(MESSAGE_BOX_STRING, MESSAGE_BOX_STRING);
//or 1000ms: ...

Platform support

This language is intended for use with Windows only, as it's STD uses WinAPI quite often. Sorry :(

Building

Currently the only option to use the compiler is to build it from source.

You'll need:

• .NET 7.0
• CMake
• C++ compiler (MSVC, MinGW, clang)

To use the app.

⚠ TODO

STD

This DSL has a STD?

Yes! Currently there's only one file (global.wal):

import 'cpp/iostream';  
  
fn print(obj) {  
    unsafe { cout << obj << endl; }  
}

unsafe represents raw C++ code.
