Visual Select Range of Lines and Sort IP Adresses

Question

I have a mapleader macro to sort IP addresses and delete leading 0 in IP addresses

let mapleader='ip'
map <leader>ips :%s/0\+\([0-9a-f]\)/\1/ | %sort n /.*\./ | %sort n /\.\d\+\./ | %sort n /\./ | %sort n u

This works but it always selects the whole text.

I am searching for a solution where I can visually select with V lines and then call a map that only this lines get sorted.

How can I do this?

Answer 1

A simple version just reuses the range provided in visual mode:

xnoremap <leader>ips :s/0\+\([0-9a-f]\)/\1/ | *sort n /.*\./ | *sort n /\.\d\+\./ | *sort n /\./ | *sort n u

• x for visual but not select mode
• noremap for a non-recursive mapping
• * for the equivalent range as '<,'>, which is a pain to type. It gets filled in automatically when you press : in visual mode though.
