How to automatically insert braces after starting a code block in vim? -

it's easy insert closing brace after typing opening one:

inoremap { {<cr>}<esc>ko 

this way

if (true) {

converts to

if (true) {     | } 

but i'd save time , type 1 character less:

if (true)<cr>

so i'd create following rule: if return pressed , line starts if/for/while, execute {<cr>}<esc>ko

is doable?

thanks

building on previous mapping, should want:

inoremap )<cr> ) {<cr>}<esc>ko 

however, should try snippet expansion plugin snipmate or ultisnips. both plugins allow define snippets placeholders , miroring (lots of them included default) expanded when <tab> pressed after trigger.

for example, have snippet associated trigger if expands into:

if ([condition]) {  } 

condition selected, ready type, and, once done, can hit <tab> again jump cursor between curly braces, ready type:

if (myvar == 5) {   | } 

this incredibly handy.
