Conditional Compilation

Conditional Compilation through chemical.mod

This is the preferred way of conditional compilation as it saves compilation time

in chemical.mod file, you can use source statements

source "src"

We can also use a if condition with this source statement like this

// include win directory only when compiling for windows
source "win" if windows

// include pos directory only when compiling for posix
source "pos" if posix

currently support for conditionals is limited, You should use a build.lab file for proper support

Conditional Compilation inside source files (experimental)

You can also just do conditional compilation in source files like this

if(def.windows) {
    // code will only run on windows
}

Please note this syntax may change to something like this in future

$if(def.windows) {}

or

if comptime(def.windows) {}

Conditional Compilation inside build.lab

since chemical code is written inside build.lab, You should just use if(def.windows) to include source files

We'll go over this in the future, build.lab features are experimental
