Question

In vim how to search for line that contain letter “foo” above the line.

Example file snippet:

class A {
    int a;
}  

class B {
     int a;
}

     // something else with 5 spaces

In this example I want to be able to search for class B since it followed by exactly 5 spaces in next line but do not my search to find Class A or the comment with 5 spaces.

Answer 1

Your question is not very clear but may be this search will work for you in vim:

/^\s*class.*\n^\s\{5}

That will search for keyword class in one line followed by exact 5 spaces in next line.
