How can I swap or replace multiple strings in code at the same time?

Question

Given the following code sample:

uint8_t i, in, ni;
i = in = 2; ni = 1;
while (2 == i > ni) in++;

How can I replace i, in, and ni<

Answer 1

In vim you can have multiple commands, separated by |, so you could do your replacement with %s command:

:%s/\/inni/ | %s/\/inin/ | %s/\/nini/

Shortly what it means:

%s/search/replacement/

searches for given search pattern and replaces it with replacement;

symbols "\<" and "\>" are standing here as word boundaries.
