Overview

Gwion is a musical programming language, similar to chuck.
It also provides high-level features, like templating and function pointers.
The main difference being an emphasis on performance.
This page is just a quick overview of the language.

Comments

Since block bock comments are a bad idea, only lines comments are enabled.

// this is a one line comment
int i; // this comment comments a int declaration

Debug print

Gwion provides a debug print syntax, quite similar to the one in chuck.

int i; // declare an int veriable named i;
<<<i>>>; // print i's type, then i's value

// debug print can handle multiple variables
int i, j:
<<<i, j>>>; // prints i's type, i's value, then j'type, j's value

Note that it will first print the type of the value if there is only one value.

11 => int i;
// so do this to print '11'
<<<i, "">>>;
