Xciel is a Xcode Extension influenced by "ci" ("di") command in Vim.

This command deletes, selects and comment-out the region (scope) where enclosed in brackets.

Unlike the "ci" command in Vim, the region is defined by the cursor position.

Introduction

Xciel commands are slightly similar to "ci" command in Vim, but these commands search the region by current cursor position.

It automatically searches the parent brackets ("(){}[]") and executes a command.

Delete

Xciel Delete command behave like the following.

(the cursor position is expressed as $)

if x.isEasy {
  do(what: $x)
}

if x.isEasy {
  do($)
}

As you can see, the cursor's scope is inside of the do(what: @x) and it deletes what: x.

By the way, if the cursor is outside of the do(), then

if !(x.isEasy) {
	waitUntilPossible()
  $do(what: x)
}

if !(x.isEasy) {
  $
}

Now, you can imagine the Delete command's behavior.

Select

Select command simply selects the scope.

Comment

Comment out command toggles lines in the scope.

NOTE: Comment out command can toggle comments in the region!

Greedy

These commands are usefull in specific situation.

Delete

This command deletes the region as same as the Select command select.

Comment out

This command comments the region as same sa the Select command select.
