C++ macros inside mta.

1. include "scriptName" - load specified file with macro support
2. ignore [n] - ignore next line, or N next lines, ignore 10 will ignore next 10 lines
3. define name value - set value under name.
4. precompile name value - same as above but value become executed and result is stores under name.
5. undef name - remove variable.
6. ifdef name - check if variables is in use.
7. ifndef name - check if variables isn't used yet.
8. if condition - skip chunk of code if result of condition equal false.
9. else - if condition was false.
10. endif - end of if.

I recommend to set uppercase name.

Macros starting with # char at start.

#define A 1
#define B 1
#precompile C A+B
print(C)

final code will be: print(2)

#define ADD1(A,B) A+B
#precompile ADD2(A,B) A+B

print(ADD1(1,2)) -- print(1+2)
print(ADD2(1,2)) -- print(3)

Simply add one line to your code:

loadstring(exports.prepocessor:install())()

where prepocessor is resource name. Then you can use dofile function that accept filename argument, example dofile("test.lua") will load test.lua with macro support
