Vim find integers in file

Question

I want to search for all integers in a file inside Vim session only without having to worry about the number of digits in the integers.
Sample file below.

aekv 27bc1 97 print
 uint32 genid;
1hd solo 20941 h1xl
1
lev 87; rex
8h fp0 4U 2

Search should put cursor at start of any of the below integers only:

97
20941
1
87
2

/\<[0-9] helps with words starting with a digit alright. But beyond that I am add mode to search for integers with any number of digits, I have tried with multiple combinations of \w, \d, etc.

Note: This is a precursor action for a substitute operation that adds a suffix U to all integers, so that they are treated as unsigned integers.

Answer 1

You can use this regex to find strings of only digits in your file:

\<\d\+\>

This matches:

• \< : a left word boundary
• \d\+ : one or more digits - note that in vim regex + (one or more) must be preceded by \
• \> : a right word boundary
