simplegen is a simple code generator library.
It is a text buffer that preserves indentation level on calls to println().
The contents of the buffer can be retrieved with to_string().
rust
fn main() {
let mut w = simplegen::IndentedPrinter::new(4);
w.println("long factorial(long n) {");
w.println_right("long acc = n;");
w.println("for (int i = 1; i < n; i++) {");
w.println_right("acc *= i;");
w.println_left("}");
w.println("return acc;");
w.println_left("});
println("{}", w.to_string());
}
C
long factorial(long n) {
long acc = n;
for (int i = 1; i < n; i++) {
acc *= i;
}
return acc;
}
