Condition Compilation support in premake

[alokprasad]

Any suggestion how to add or remove functions from C files based what is selected in Build , without the typical use of #ifdef.

Config.cfg

<Feature1>
func1
func2
func3
structA:varB ( Variable B is specific to Feature1)
</Feature1>

<Feature2>
func4
func5
func6
structA:varD ( Variable D is specific to Feature2)
</Feature2>

So if in Build system i want to select Feature2 it should only INclude Func4,5,6 for compilation and remove other variables and Function not selected.

Typical C way #ifdef will be

#ifdef Feature1
func1() {
}
func2() {
}
func3() {
}
#endif

StructA {
#ifdef Feature1
var B
#endif
}

I want to avoid excessive use of Ifdef , is there any better way to do so

How to do that in premake.

If you need the functions in the same file, you're stuck with doing it the "C way". Otherwise, you can put them in different files and then include those files with a filter based on whatever it is that controls your features.
