I do have a bunch of XHTML files and I need to put an @id for all the p elements inside all those files.

I have tried the following argdo approach in the following way:

:cd d:\testfiles\
:args *.xhtml
:argdo let i = 1 | g/<p/s/<p/\=printf("<p id=\"para%02d\"", i)/ | let i = i + 1

Now, this works fine. Doing it by this way value of i is getting incremented all the time. But, I want it to use unlet i, whenever argdo executes to a new buffer. In short, variable i must be set to 1 for each item in the arg-list.

I also have tried to use |unlet i at the end of the argdo statements or at the beginning of the argdo statements. But both ways have failed.


Is there any workaround? I am very new to vim. Using it only a few months and loving it day by day. Pointing out my error to get job done, is greatly appreciated.

    @muru: thanks a ton! This is so easy...and I was heard of that...but never used it before... – Cylian Feb 6 '16 at 10:22
  • both the ways are failed is incorrect grammatically - it should be either both ways have failed, or just both ways failed. – muru Feb 6 '16 at 10:45

When you use a variable without a scope (i instead of b:i or w:i, etc.) outside of a function, you're using a global variable. From :h internal-variables:

There are several name spaces for variables.  Which one is to be used is
specified by what is prepended:

                (nothing) In a function: local to a function; otherwise: global
buffer-variable    b:   Local to the current buffer.
window-variable    w:   Local to the current window.
tabpage-variable   t:   Local to the current tab page.
global-variable    g:   Global.
local-variable     l:   Local to a function.
script-variable    s:   Local to a :source'ed Vim script.
function-argument  a:   Function argument (only inside a function).
vim-variable       v:   Global, predefined by Vim.

A plain i is a variable common to all buffers. Since you need to reset the variable for each file, and each file will be in a separate buffer, you can use buffer-local variables (b:i instead of i).
