pub struct ConvertPrintfs;

convert_printfs Command

Usage: convert_printfs

Marks: none

Converts each call to printf(...) and fprintf(stderr, ...) into equivalent print!, println!, eprint! or eprintln! calls.

This command checks that the callees are foreign functions imported using extern "C" and marked #[no_mangle], to make sure the caller is actually calling the libc functions.

Example:

printf("Number: %d\n", 123);

gets converted to:

print!("Number: {}\n", 123);
