Program basics

Let’s have a look at how an OPENRNDR program is structured. Most programs will share a structure like the one below.

fun main() = application {
    configure {
    // set Configuration options here
    }
    
    program {
        // -- what is here is executed once
        extend {
        // -- what is here is executed 'as often as possible'
        }
    }
}

application

The application block is used to setup the run-time environment of the software we are writing. This block houses two other blocks: configure and program. Think of it as an OPENRNDR application.
