Question

I have a file full of C++ code which is a bunch of small functions that return a number. I am trying to replace each number with the number plus one if the number is greater than 2. So,

int blah() { return 5; }

would become

int blah() { return 6; }

but

int blah() { return 1; }

would remain the same.

How is this done?

Answer 1

A bit ugly, but should work:

s/\{\s*return\s+(\d+)\s*;\s*\}/$1 > 2 ? "{ return " . ($1 + 1) . "; }" : $&/ge;
