what is the best way to edit similar strings?

I need to make 开发者_JAVA技巧next task:

file:

string1 data1 data

I need to create more strings with only changes in digits

string2 data2 data
string3 data3 data
string4 data4 data

How can i do it fast ?

select that input line, yank it into buffer a: "ayy.

Then record the following sequence: qq

1. "ap Paste the line below
2. ctrl-a Increment the digit
3. w Move forward one word
4. ctrl-a Increment the digit
5. "ayy Yank this line in as your new baseline

End your macro with q

Then repeat it as many times as you need (let's say 42), with 42@q

Several plugins manage that: visincr.vim, increment.vim.

I use visincr and that is very easy: Visual block, :I.
