vim-surround: mapping for {<cr>

[hieulmhe176232]

I want to create a mapping that wrap selection with {<cr>, so that:

selection

will become:

{
selection
}

Attempt: visual selection, then pressS{ to become this:

{ selection }

Visual again by vi{, then press S<cr>.

It works, but need too many strokes. So that i create a mapping:

xmap gS{ S{vi{S<cr>

But it only become:

{ selection }

sorry for my bad english.

I found a solution by using macro:

let @s="gvS\<CR>w"
xmap gSb Sbvib<esc>@s
xmap gSB SBviB<esc>@s
xmap gS) S)vi)<esc>@s
xmap gS( S(vi(<esc>@s
xmap gS{ S{vi{<esc>@s
xmap gS} S}vi}<esc>@s

But then have new problem, gSt will not work because it need to type tag
