How to subtract from numbers following a string in VIM?
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I am trying to subtract from numbers following a string in VIM, for example this (searched) input:
CustomModelData: 1
And my preferred (replaced) output:
CustomModelData: -2147483647
The number that I am trying to subtract from the numbers is 2147483648. I tried using this in VIM, but it doesn't work since there is a string in the expression, I want to keep the string while also subtracting from the number that follows:
:%s/CustomModelData: d+/=/CustomModelData: submatch(0)-2147483648/g
vim

Do you have to use vim for this problem? Tools such as awk can do a much better job:awk -F ': ' 'BEGIN { OFS=": "} {print $1, $2 - 2147483648}' data-file

No, I never considered using awk, I will try it out.

I tried entering the command and I got this error: awk: cmd. line:1: BEGIN { OFS=: awk: cmd. line:1: ^ syntax error errcount: 1

Nov 17 '18 at 5:23
Can you tryawk -F ': ' 'BEGIN {OFS=FS} {print $1, $2 - 2147483648}' data-file

It seems to work, but it doesn't seem to go throughout the file (it only does the first one), and also, I had to add the "CustomModelData" before the first colon to make it work.

You can use following minor adjustment to have the match start at the number so the replacement only sees the number to adjust
%s/vCustomModelData: zsd+/=submatch(0)-2147483648/g
- zs anything, sets start of match

If each number is on a separate line of the file, then you can match relevant lines and use the Ctrl+X subtraction operator on them:
:g/CustomModelData:/ norm 2147483648^X
(For the ^X, type Ctrl+X.)
