Your first program

As of version 0.1.0 of the compiler, not many feature are available. We recommend to wait at least for version 0.2.0 or better first stable version 1.0.0 to have a better set of feature.

Let's do some computation

Fil code is written in .fil file.

In this first program we'll write a little script which compute the result of operation 3 * 2 + 4 in a variable and then return the result as exit code.

// main.fil
val result = 3 * 2 + 4

This line declare a constant in which we store the result of our operation. As the declaration is an expression it returns a value, the constant's one. The compiler will then use this value as the exit code. If your program has multiple expression, the value of the last expression is used as exit code.

To compile your program run this command

filc main.fil

The result is an object file. You need to use ld or a compiler like gcc to transform it to an executable. You then execute it and the exit code of it should be 10.
