Add "text object" support for Vi mode

[gwojan]

It would be really nice if Vi mode supported text objects so things like:

ci{
da{
ci[
ci"
ci'
etc...

were possible.

Indeed - I might have mentioned this to @srdubya a long time ago. I might even switch to vi mode if this was implemented. (I use vim or vim bindings in my editors.)

[gwojan]

Yeah, my workaround when I really want to get nasty is set $env:VISUAL = 'vim.exe' and then edit the whole thing inside vim proper...

I'm even using the wasavi extension for chrome and editing this comment inside a vim-like editor. Yes, I'm sad... 😉

I’m working on this issue.

This will probably need to be broken up into several pull requests. This is how I see tackling this subject in order:

• [x] n diw: deletes inner words. #2059. 🍾

• [ ] n ciw: changes inner words.

• [ ] n diW: deletes inner WORDs.

• [ ] n ciW: changes inner WORDs.

• [x] di [ " | ' ]: deletes inner strings. #3791.

• [ ] ci [ " | ' ]: changes inner strings.

• [ ] di [ ( | { | [ ]: deletes inner parentheses.

• [ ] ci [ ( | { | [ ]: changes inner parentheses.

• [ ] n daw: deletes outer words.

• [ ] n caw: changes outer words.

• [ ] n daW: deletes outer WORDs.

• [ ] n caW: changes outer WORDs.

• [ ] da [ " | ' ]: deletes outer strings.

• [ ] ca [ " | ' ]: changes outer strings.

• [ ] n da [ ( | { | [ ]: deletes outer parentheses.

• [ ] n ca [ ( | { | [ ]: changes outer parentheses.

I don’t see the immediate value for other more arcane text objects 😄.

Hello,

I worked on some custom key handler for ci, ca, di and da as it really make editing more fluent. At the moment I only address ' " ( [ {
