Let's say I have the following:
(let ([x (foo bar)] ... )
In the regular drracket editor, when I move the cursor between the ) and ]
it highlights (foo bar). In the vim emulator, the cursor has been replaced
by a block that highlights a character, rather than a line just before it.
So the same cursor position would display a box over the ] rather than a
line between ) and ], and therefore backward-sexp needs to match the [
rather than the (.
There is the following code in the vim editor to handle explicitly hitting
%:
;; implements the behavior of "%" and friends in vim
(define/private (do-matching-paren action)
(define pos-box (box 0))
(get-position pos-box)
(define pos (unbox pos-box))
(define char (get-character pos))
(match char
[(or #\) #\] #\})
(action 'backward (get-backward-sexp (add1 pos))
(add1 pos))]
and I was trying to do the same for highlighting the sexp when the cursor
is over the closing ), but I can't figure it out.
