Compile time versioning

Part of VersioningCategory

Description

Shows how to do versioning in files at compile time.

Example

// By Joey Peters

// pass -version=free to dmd
version(Free) {
 version = FeatureA;
} else {
 version = FeatureA;
 version = FeatureB;
}


void main() {
 // every version has this.
 version(FeatureA) {
   printf("Hello world!");
 }
 // only the non free has this
 version(FeatureB) {
   printf("Deluxe!");
 }
}


/*
The equivalent of #define CONTRACT would be:
version = CONTRACT
Though, I must add you should not use capitals like you're used to ;)
The equivalent of #ifdef ... #endif is:
version(...) {

}
The equivalent of #ifdef ... #else #endif is:
version(...) {

} else {

}
