Static ifs

static ifs are like normal ifs, except that a) the condition must contain only constant booleans, the and operator and the not operator and b) They are evaluated during compile time. Which means that the code that is not matched to its condition is simply ignored.

library OptionalCode requires optional UnitKiller

    globals
        constant boolean DO_KILL_LIB = true
    endglobals

    function fun takes nothing returns nothing
        local unit u = GetTriggerUnit()
        //the following code may need to kill the unit
        //but is alternatively able to use the external
        //'UnitKiller' library to do the library.
        // ONLY when DO_KILL_LIB is true AND the
        // library UnitKiller is in the map.
        static if DO_KILL_LIB and LIBRARY_UnitKiller then
            //static if because if the UnitKiller
            // library was not in the map, using a normal
            // if would not remove this line of code and
            // therefore it would cause a syntax error.
            // (unable to find function UnitKiller)
            call UnitKiller(u)
        else
            call KillUnit(u)
        endif
    endfunction

endlibrary

library UnitKiller

    function UnitKiller(unit u)
        call BJDebugMsg("Unit kill!")
        call KillUnit(u)
    endfunction

endfunction
