Hi all,
I can do this in C++.
#include <iostream>
using namespace std ;
#define end };
#define log(x) cout << x << endl
#define wait std::cin.get()
int main() {
log("Trying to avoid the visual clutter aused by closing
curly braces") ;
string myStr = "Now, code looks more elegant" ;
log(myStr) ;
wait ;
end
How can i do this in D ? Especially the " #define end }; ".
I've tried " alias end = } " but didn't worked.
Edit : How can add syntax highlighting and coloring in code
posted on this comment ?
If this is about logging functionality, check
std.experimental.log package, it contains all necessary logging
functionality.
About macros there aren't any similar to preprocessor macros in
c/c++, however you can replace them with three options depending
on your needs:
1. Just a simple function in conjunction eith ctfe:
https://tour.dlang.org/tour/en/gems/compile-time-function-evaluation-ctfe
2. string mixins: https://dlang.org/articles/mixin.html
3. template mixins: https://dlang.org/spec/template-mixin.html
I'd say number 2 should be suitable for your example given you'd
like to inject statements into body of some function.
Best regards,
