Multiline paste with relative columns alignment

Question

When I have some text indented as follows (like a and b variables assignment):

if(condition)
    a = 1;
    b = 2;
end

and I want to paste a and b block somewhere outside of the if block, i.e just after it, vim adds the indentation starting from the second line of visual selection, resulting:

a = 1;
    b = 1;

Does exist such an option that don't expand the indentation (better said that maintains relative column alignment for each line) when text is pasted, without using a custom function ?

EDIT: I mainly use gvim.

EDIT2: I have already tried set paste and set nopaste without success.

AFAIK, there is no direct way to do that in Vim.

Here is a workaround:

First of all I have the following mapping in my vimrc (From Vim Tips Wiki, Tip 759):

nnoremap <expr> gp '`[' . strpart(getregtype(), 0, 1) . '`]'

With this you can visually select the text you have just pasted (or changed).

Note that gp is already used by Vim for

Just like "p", but leave the cursor just after the new text.

So the mapping shadows the default functionality of gp. Maybe you want to change the mapping.

Then I do

1. Copy the text
2. Paste it with p (or P)
3. Reselect the pasted text with gp (the mapping above)
4. Reformat with = (or un-indent it with <)

Or short: pgp=
