on_cr fully in insert mode!

[Sam-programs]

after carefully reading most of indent.txt

i found a way to make Return expansion work fully in insert mode with keys,
using cinkeys and indentkeys

={motion}   Filter {motion} lines through the external program
			given with the 'equalprg' option.  When the 'equalprg'
			option is empty (this is the default), use the
			internal formatting function |C-indenting| and
			|'lisp'|.  But when 'indentexpr' is not empty, it will
			be used instead |indent-expression|.

i replicated in insert everything except for equalprg as am not sure how it can be helpful, since we are only indenting 1 line

i also changed the way pairs are placed

     {

|} format

     {
| format to set the cursor position
     }

how should i go about undo blocks ?
old me made it have no undo blocks for endwise pairs
and have undo blocks around none-endwise pairs
i feel like i should have undo-blocks around in both cases
because expanding a pair is it's own operation

the indenting is a bit unstable with ctrl-f when a pair is under the cursor i am gonna close this

nvm the flickering issues are related to neovim and lualine.
