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) ; mixin template cToD(string code)
`log` and `wait` are straightforward. Just write a function:
import std.stdio;
void log(T)(T x) { writeln(x); }
void wait() { readln(); }
However, you can't do things like `#define end }`. The D language
intentionally disallows doing stuff like this. If you *really*
want to do this, you can sort of emulate it with mixins:
mixin template cToD(string code)
{
import std.array: replace;
mixin(code.replace("end", "}"));
}
mixin cToD!`
int main() {
log("Trying to avoid the visual clutter aused by closing
curly braces") ;
string myStr = "Now, code looks more elegant" ;
log(myStr) ;
wait ;
return 0;
end
`;
But I would strongly recommend against it.
